DETAILED DESCRIPTION

[0158] Embodiments showing objects, features, and effects of the present disclosure are described below.

[0159] (1) First Embodiment (Vertical Axis Type Wind Power Generation Mechanism 11)

[0160] A first embodiment of the present disclosure will be described below with reference to the accompanying drawings. Hereinafter, in the specification, a wind power generator 1 of the first embodiment may be referred to as a “vertical axis type”. FIGS. 1 and 2 illustrate a configuration of a vertical axis type wind power generation mechanism 11 according to the first embodiment of the present disclosure.

[0161] (Overall Configuration)

[0162] FIG. 1 is a perspective view illustrating the vertical axis type wind power generation mechanism 11 according to the first embodiment of the present disclosure. In FIG. 1, the vertical axis type wind power generation mechanism 11 has a mount 51, a windmill 30, a wind collector 20 that collects wind and accelerates the wind traveling toward a blade 32, and a generator A40a.

[0163] As illustrated in FIG. 1, the wind power generator of the first embodiment of the present disclosure has a shape in which an entire outer periphery of the cross-flow type windmill 30 which is the vertical axis type wind power generation mechanism 11 is surrounded by the wind collector 20.

[0164] (Windmill 30)

[0165] In FIG. 1, the windmill 30 is rotatably supported on the mount 51 and connected to an input shaft of the generator 40a, and includes a windmill rotation shaft 31 erected in a direction perpendicular to a traveling direction of the wind, and a plurality of blades 32 which are arranged along a circumference of the windmill rotation shaft 31 and give rotational torque to the windmill rotation shaft 31 by receiving wind.

[0166] (Wind Collector 20)

[0167] As illustrated in FIGS. 1 and 2, the entire outer periphery of the wind collector 20 of this example is surrounded by a plurality of wind collecting ducts having a substantially triangular prism shape in appearance. According to this wind collecting duct, winds W flow into the wind collecting duct through intakes of a plurality of wind collecting ducts surrounding an outer periphery of the windmill and flow out to the windmill through outlets of the wind collecting ducts. As illustrated in FIG. 2, a direction of the winds W flowing into the windmill is clockwise when viewed from above, and always hits the blade of the windmill with a favorable wind. An unfavorable wind for the blade of the windmill is blocked by a duct wall of the wind collecting duct so that it does not flow into the windmill.

[0168] Moreover, the wind collecting duct of the example of the present disclosure has a three-dimensional tubular shape in which an intake 22, which is an inlet port of wind, is widened to increase an area for receiving wind and an inner diameter is gradually narrowed toward a tip. Due to this shape, the wind to the windmill 30 is accelerated because the wind collecting duct is formed such that the inner diameter of the wind collecting duct decreases from the intake 22 to the outlet.

[0169] The wind collector 20 of the present example allows wind from about 120 degrees to about 180 degrees forward angle to flow to the blades 32 inside the windmill as favorable winds while blocking head wind.

[0170] As a result, by using the wind collector 20 of the present example, it is possible to increase a windmill rotation speed by enlarging the wind receiving area, blocking the head wind, and increasing the wind force.

[0171] As illustrated in FIGS. 1 and 2, in the wind collector 20 of this example, adjacent wind collecting ducts are partially overlapped and attached so as to cover the entire outer periphery of the windmill 30, making it a three-dimensional shape that maximizes the use of wind. However, adjacent wind collecting ducts may be attached so as to cover the entire outer periphery of the windmill 30 in a state that they are separated from each other without partially overlapping each other.

[0172] (Arm)

[0173] In FIG. 1, an arm that connects the windmill rotation shaft 31 and the blade 32 is a disk-shaped arm 35 that fixes upper and lower portions of the blade 32 with a disk in this example. This is because the vertical axis type wind power generation mechanism 11 solves the problem that the number of rotations changes depending on strength of the wind, and a fatigue load at a base of a blade frame is caused by an inertial force.

[0174] However, for example, other types of arms can be employed besides disk-shaped arms. For example, as illustrated in FIGS. 3A and 3B, when upper and lower tips of a blade 321 are provided with winglets 33, the blade 321 can be supported by a rod-shaped arm 36 instead of the disk-shaped arm 35.

[0175] Further, in another example, the shape of the arm connecting the windmill rotation shaft 31 and the blade may be a rotating blade shape, or, although not illustrated, a rotating blade-shaped spoke blade 38 may be formed on an arm that connects the windmill rotation shaft 31 and the blade.

[0176] (Blade 321)

[0177] In FIG. 1, the blades 32 in this example employ a plurality of vertical blades 32. Although a linear shape is adopted in this example, a curved shape may be used.

[0178] In this example, the interval between the blades of the windmill 30 is relatively large. As a result, the shape is such that high-speed rotation is possible.

[0179] (Winglet 33)

[0180] In the example illustrated in FIGS. 3A and 3B, the upper and lower tips of the blade 321 are the winglets 33. This reduces occurrence of wingtip vortices, achieving efficient rotation and noise prevention. Straight blades of the related art let wind escape from tips, causing wing tip stall. In order to eliminate the wing tip stall, the wing has the winglet 33 with the wing tip bent inward. It has been confirmed by a rotation test that by using the winglet 33 as the blade tip of the cross-flow type windmill 30, the windmill rotation speed is increased by about 25%.

[0181] The reason why the winglet shape improves the windmill rotation speed is thought to be that by attaching an inner blade 54 to the winglet 33 at the tip of the blade and the blade 32, the wind can be received most effectively, and the lift force and the drag force can be utilized, so this reduces generation of a wingtip vortex, which is a negative factor.

[0182] (Inner Blade 54)

[0183] As illustrated in FIGS. 3A and 3B, by attaching the inner blade 54 to a tip of the blade 32 on a rotation direction (advance) side, it is possible to easily receive the wind and utilize the effects of drag and lift, increasing the rotation speed of the blade 32. That is, it has been confirmed that when the inner blades 54 are attached, the windmill rotation speed is improved by about 20%.

[0184] An attachment angle of the inner blades 54 is preferably within a range of 45 degrees to 90 degrees. A rotation test confirmed that the angle in this range was the most effective.

[0185] When the vertical axis type windmill of this embodiment is used alone, the windmills can be vertically connected in two or three stages in a comb shape. Since the windmill used in the vertical axis type wind power generation mechanism 11 of the present disclosure has a wide blade area and a large torque, a plurality of windmills can be vertically connected in a comb shape and connected to one generator. Thereby, the power generation amount can be increased.

[0186] (Generator 40a)

[0187] The generator A40a is directly connected to the windmill rotation shaft 31 by a generator support means (not illustrated) at the bottom of the windmill 30. In this example, although the windmill rotation shaft 31 is formed with the same rotating shaft as a rotation shaft of the generator 40a, the windmill rotation shaft 31 may be joined to the rotation shaft of the generator 40a by a shaft coupling.

[0188] (Support Mechanism)

[0189] In this example, the support mechanism includes the mount 51 and an attitude control means 53. The attitude of the windmill 30 and the wind collector 20 can be horizontally adjusted by a turntable (not illustrated) provided on the mount 51. An attitude control shaft 53 allows an orientation adjustment of the windmill 30 and the wind collector 20 in a vertical direction. In this specification, the attitude control is that the orientation of the altitude of the windmill and the wind collector is adjusted horizontally and vertically.

[0190] (Operation Effect)

[0191] An operation effect of the wind power generator 1 of the first embodiment will be described.

[0192] Focusing on the fact that the amount of power generated by wind power is proportional to the cube of the wind speed, by attaching the three-dimensional wind collectors 20 of approximately triangular prism shape around the windmill, the wind hitting the windmill 30 can be accelerated to achieve a significant increase in power output. Applying this wind collector 20 to the vertical axis type wind power generation mechanism 11 to collect the wind and concentrate a wind energy to accelerate the wind, and thus it is possible to improve start-up characteristics, which is a problem of the vertical axis type wind power generation mechanism 11, and to greatly increase the power generation output.

[0193] (2) Second Embodiment (Horizontal Axis Type Wind Power Generation Mechanism 12)

[0194] Next, referring to FIG. 5, a horizontal axis type wind power generation mechanism 12 as a second embodiment of the present disclosure will be described. In the second embodiment, components similar to those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted. Hereinafter, in the specification, the horizontal axis type wind power generation mechanism 12 of the second embodiment may be referred to as “horizontal axis type”. The second embodiment differs from the first embodiment in that the horizontal axis type wind power generation mechanism 12 is used as the wind power generation mechanism.

[0195] (Overall Shape)

[0196] In FIG. 5, the horizontal axis type wind power generation mechanism 12 of the second embodiment includes the mount 51, the windmill 30, a blade 322, the wind collector 20, and a generator A40b.

[0197] (Wind Collector 20)

[0198] In the second embodiment, the wind collector 20 is not particularly limited as long as it can collect wind and direct it to the windmill. In this example, a bell mouth duct is used which facilitates the collection of air.

[0199] (Spinner 21)

[0200] In this example, a spinner 21 having a conical shape is attached to a central portion of the multi-blade fan 322. As a result, resistance and turbulence can be reduced, and wind can be collected efficiently.

[0201] (Blade 322)

[0202] In this second embodiment, the multi-blade fan 322 is used as the blade 322 inside the bell mouth duct. Generally, a multi-blade fan has a rotation capacity of 6,000 rotations or more, but when used for wind power generation, sufficient power generation is possible even at about 1,000 rotations. The multi-blade fan is usually used for blowing air, but in the case of wind power generation, it is used for receiving wind (reverse pitch), so there is an advantage that noise is small.

[0203] Although there is no particular limitation on the number of blades of the multi-blade fan 322, in the demonstration experiment by the present inventor, regarding the number of blades 322, in the comparative verification test of three blades and nine blades, the number of rotations of nine blades was about twice the number of rotations of three blades. As a result, nine blades were used in this example.

[0204] The most important thing in the high speed rotation of the windmill is to minimize the wind passing through the inside of the windmill and make the best use of the wind. Since the wind energy received by the windmill is the same, it is important to reduce air losses and improve the efficiency of the wind received.

[0205] In this example, the shape of the blade 322 is devised so that the area of the blade 322 that receives the wind is increased and the maximum amount of wind received is possible.

[0206] That is, in the horizontal axis type wind power generation mechanism 12 of this embodiment, when viewed from a direction of the windmill rotation shaft, it is preferable that the adjacent blades 322 of the plurality of blades 322 are overlapped with each other so that there is no gap and almost all of the wind receiving portion of the horizontal type windmill is covered, and further, it is preferable to form the blade so that there is almost no gap between the tip of the blade 322 and the bell mouth duct. That is, when viewed from the direction of the windmill rotation shaft, it is preferable that a projected area of the plurality of blades 322 is formed so as to cover almost all of the wind receiving portion of the horizontal axis type windmill. The width and length of the blades of the multi-blade fan horizontal axis type windmill are preferably formed to a blade width such that when the windmill is viewed from the direction of the windmill rotation shaft, the blades overlap each other and cover almost all of the wind receiving portion, and preferably formed to a blade length so that there is almost no gap between the tips of the blades and the bell mouth duct when the windmill is viewed from the direction of the windmill rotation shaft.

[0207] (Double Blade 32)

[0208] Multi-blade fans can be coaxially stacked to form a blade structure with two or more continuous blades. Thereby, the power generation amount can be further increased.

[0209] (Generator)

[0210] In this embodiment, the windmill rotation shaft 31 is directly connected to the generator 40. Therefore, it is possible to reduce the size of the wind power generator. In this example, although the windmill rotation shaft 31 is formed with the same rotating shaft as a rotation shaft of the generator 40a, the windmill rotation shaft 31 may be joined to the rotation shaft of the generator 40a by a shaft coupling.

[0211] (Stabilizer)

[0212] A vertical stabilizer can also be attached to an upper portion of the bell mouth duct to control the direction. By attaching the vertical stabilizer, the horizontal axis type wind power generation mechanism 12 can be made to face a wind direction and generate power efficiently.

[0213] (Protective Cover)

[0214] A protective cover such as a net can be attached to a wind collecting port of the bell mouth duct. By attaching the protective cover, a finger can be prevented from getting caught and a bird strike can be prevented.

[0215] (Safety)

[0216] The blade 322 preferably has a short diameter. That is, when the diameter of the blade 322 is short, the strength of the blade 322 is increased, and high safety can be ensured. Since a peripheral speed ratio between a root portion and a tip portion of the blade 322 does not change, efficient rotation can be realized even with the blade 322 having a short diameter. Further, it is possible to ensure high safety and achieve high-speed rotation by increasing the strength.

[0217] (Operation)

[0218] The most important thing in the high speed rotation of the horizontal axis type wind power generation mechanism 12 is to minimize the wind passing through the inside of the windmill and make the best use of the wind. Since the wind energy received by the windmill 30 is the same, it is important to reduce air losses and improve the efficiency of the wind received.

[0219] The horizontal axis type wind power generation mechanism 12 of this example has the bell mouth duct and the spinner 21, and the blade 322 has a short diameter and the blades overlap each other. By narrowing the interval between the bell mouth duct 23 and the blade 322, almost all of the wind receiving area of the horizontal axis type wind power generation mechanism 12 becomes the area of the blades 32, and thus the most efficient wind reception is possible. As a result, high-speed rotation can be achieved. Noise can be reduced by the short blade diameter and a gap with respect to the narrow bell mouth duct 23.

[0220] (3) Third Embodiment (Integrated Type Wind Power Generation Mechanism 13)

[0221] An integrated type wind power generation mechanism 13, which is a third embodiment of the present disclosure, will be described with reference to FIGS. 6 to 10. In the third embodiment, in principle, the same reference numerals are given to the similar components as in the first embodiment and the second embodiment, and detailed description thereof will be omitted.

[0222] As illustrated in FIGS. 6 to 10, in the third embodiment, a difference is that the wind power generation mechanism is a wind power generation mechanism in which the vertical axis type wind power generation mechanism 11 of the first embodiment and the horizontal axis type wind power generation mechanism 12 of the second embodiment are combined and integrated.

[0223] Hereinafter, the wind power generator 1 of the third embodiment may be referred to as “integrated type”, “integrated type wind power generation mechanism 13”, or “integrated type wind power generation mechanism 13” in the specification.

[0224] As for the integrated type wind power generation mechanism 13, the description of each of the vertical axis type wind power generation mechanism 11 and the horizontal axis type wind power generation mechanism 12 is as described above, so it will be omitted to avoid duplication, and the necessary description will be described in detail below.

[0225] In addition, although in the vertical axis type wind power generation mechanism 11 of the first embodiment, as an example, the disk-shaped arm 35 is adopted in a windmill portion, the vertical axis wind type power generation mechanism 11 part of the integrated type wind power generation mechanism 13 described below differs in that, as an example, a rod-shaped arm is used in the windmill portion.

[0226] (Overall Shape)

[0227] FIG. 6 is a cross-sectional explanatory view illustrating a state in which the integrated type wind power generation mechanism 13 is installed horizontally, viewed from a lateral side, and illustrating the internal structure.

[0228] FIG. 7 is a plan view, half of which is an illustration of the inside.

[0229] FIG. 8 is a rear view of the integrated type wind power generation mechanism 13.

[0230] FIG. 9 is a front view of the integrated type wind power generation mechanism 13.

[0231] FIG. 10 is a side view of the integrated type wind power generation mechanism 13 installed vertically.

[0232] The integrated type wind power generation mechanism 13 of the present disclosure includes the mount 51, the vertical axis type wind power generation mechanism 11, and the horizontal axis type wind power generation mechanism 12. The integrated type wind power generation mechanism 13 uses a wind power generation mechanism in which the vertical axis type wind power generation mechanism 11 and the horizontal axis type wind power generation mechanism 12 are integrated as a wind power generation mechanism.

[0233] That is, as illustrated in FIG. 6, in the integrated type wind power generation mechanism 13, a horizontal axis type windmill rear end portion 26 of the horizontal axis type wind power generation mechanism 12 and a vertical axis type windmill bottom end portion 25 of the vertical axis type wind power generation mechanism 11 are connected by a connecting member 27 to be integrated.

[0234] The integrated type wind power generation mechanism 13 is integrated in a form in which the horizontal axis type wind power generation mechanism 12 is arranged in front and the vertical axis type wind power generation mechanism 11 is arranged in the rear, and the integrated type wind power generation mechanism 13 can be used by mounting the horizontal axis type wind power generation mechanism 12 on a moving body so as to face a traveling direction of the moving body.

[0235] As illustrated in FIG. 7, the integrated type wind power generation mechanism 13 is attached to the mount 51 by the attitude control shaft 53 which is the attitude control means capable of adjusting the direction of the integrated type wind power generation mechanism 13 vertically and horizontally.

[0236] FIGS. 6 and 7 illustrate a state in which the wind power generator 1 of the integrated type wind power generation mechanism 13 is installed in a horizontal state such that the horizontal axis type wind power generation mechanism 12 part receives the wind W. FIG. 10 illustrates a state in which the vertical axis type wind power generation mechanism 11 part of the integrated type wind power generation mechanism 13 is installed vertically so as to receive the wind W.

[0237] In the integrated type wind power generation mechanism 13 illustrated in FIG. 6, the windmill 30 of the vertical axis type wind power generation mechanism 11 employs the blades 321 supported by spokes 39.

[0238] Further, both the vertical axis type wind power generation mechanism 11 and the horizontal axis type wind power generation mechanism 12, the generators A40a and A40b are directly connected to windmill rotation shafts 31a and 31b, respectively.

[0239] In this example, the windmill rotation shaft 31 is formed with the same rotating shaft as the rotation shaft of the generator 40a, but the windmill rotation shaft 31 may be joined to the rotation shaft of the generator 40a with a shaft coupling.

[0240] (Mount 51—Left and Right)

[0241] The integrated type wind power generation mechanism 13 can arbitrarily change an orientation in a horizontal direction by the mount 51 to realize the most efficient power generation. That is, by installing a turntable (not illustrated) on the mount 51, it is possible to arbitrarily change the orientation in the horizontal direction by rotating the turntable so as to face a wind direction. In addition, by attaching a vertical stabilizer (stabilizer) (not illustrated) on the upper portion of the integrated type wind power generation mechanism 13, the integrated type wind power generation mechanism 13 of the integrated type wind power generator of the present disclosure can automatically face the wind for efficient power generation.

[0242] (Mount 51—Up and Down)

[0243] In addition, the integrated type wind power generation mechanism 13 can change an installation angle in a vertical direction by the attitude control shaft 53 of the mount 51, so the integrated type wind power generation mechanism 13 can be oriented parallel to the ground or angled from the horizontal.

[0244] As a result, the integrated type wind power generation mechanism 13 in the horizontal state as illustrated in FIG. 6 can be tilted rearward 90 degrees to change its orientation to the vertical state as illustrated in FIG. 10. Further, by installing a turntable on the mount, it is possible to rotate the integrated type wind power generation mechanism 13 180 degrees, so the integrated type wind power generation mechanism 13 can face the wind direction.

[0245] Although the wind power generator 1 of the present disclosure configured as described above is not strictly limited in size and weight, preferably, the wind power generator 1 is less than approximately 1 meter in length, width, and height and weighs less than approximately 30 kilograms to 50 kilograms. Therefore, the small-sized wind power generator of the present disclosure can be installed not only in a stationary state to generate wind power, but also in a moving body such as an automobile, a ship, or an aircraft to generate wind power.

[0246] (When Mounted on Moving Body and Moved)

[0247] When traveling with the integrated type wind power generation mechanism 13 installed on a moving body such as an automobile, a ship, or an aircraft, the wind direction is constant only from the traveling direction. In this case, the horizontal axis type wind power generation mechanism 12 in which the entire windmill receives wind and generates power operates efficiently. Therefore, when the moving body moves forward, the integrated type wind power generation mechanism 13 is placed in a horizontal state so that the horizontal axis type wind power generation mechanism 12 is oriented parallel to the ground. As a result, the integrated type wind power generation mechanism 13 of the present embodiment can efficiently generate power when a moving object is travelled with the integrated type wind power generation mechanism 13 installed thereon.

[0248] (Spoke Blade 38 Rotating Blade)

[0249] In the integrated type wind power generation mechanism 13 of this embodiment, as illustrated in the vertical axis type wind power generation mechanism 11 part of FIG. 6, the rotating blade-shaped spoke blade 38 may be formed on an arm connecting the windmill rotation shaft 31 and the blade 321, or the shape of the arm connecting the windmill rotation shaft 31a and the blade 321 can be formed into the spoke blade 38 having the shape of a rotating blade.

[0250] As a result, in the integrated type wind power generation mechanism 13 of this embodiment, the wind W passes through the inside of the horizontal axis type wind power generation mechanism 12 and flows into the vertical axis type wind power generation mechanism 11 as it is, so that the spoke blades 38 of the vertical axis type wind power generation mechanism 11 can be given a rotational force.

[0251] Therefore, even when the integrated type wind power generation mechanism 13 is mounted on a moving body such as an automobile and the moving body is traveling, the vertical axis type wind power generation mechanism 11 of the integrated type wind power generation mechanism 13 can generate power without rest. As a result, favorable power generation efficiency can be obtained.

[0252] (When Moving Body is Stopped)

[0253] When the moving body is stopped as in the case of arriving at a destination, the attachment angle of the integrated type wind power generation mechanism 13 is changed so as to tilt the integrated type wind power generation mechanism 13 in the horizontal state rearward 90 degrees to change its orientation to a vertical state as illustrated in FIG. 10, and by making the integrated type wind power generation mechanism 13 vertical so that the vertical axis type wind power generation mechanism 11 can receive the wind W efficiently, the integrated type wind power generation mechanism 13 can efficiently generate power.

[0254] Therefore, the wind power generator 1 of the third embodiment of the present disclosure can effectively generate power even when the direction of the wind is not constant, such as when the moving body is stopped.

[0255] In the wind power generator 1 of the third embodiment of the present disclosure, as illustrated in FIG. 10, the horizontal axis type wind power generation mechanism 12 is connected to a lower portion of the vertical axis type wind power generation mechanism 11. However, it is also possible to turn the horizontal axis type wind power generation mechanism 12 up and the vertical axis type wind power generation mechanism 11 down. In this case, the multi-blade fan of the horizontal axis type wind power generation mechanism 12 faces upward.

[0256] (Simultaneous Power Generation)

[0257] As described above, in the wind power generator 1 of the third embodiment of the present disclosure, when the horizontal axis type wind power generation mechanism 12 generates power while a moving body such as an automobile is moving, the vertical axis type wind power generation mechanism 11 located behind the horizontal axis type wind power generation mechanism 12 can also generate power at the same time.

[0258] That is, in this example, as illustrated in FIG. 6, the spoke blade 38 is formed on a rod-shaped arm that connects the windmill rotation shaft 31 and the blade 321 of the vertical axis type wind power generation mechanism 11, and the shape of the spoke blade 38 is a rotating blade shape. Therefore, a total amount of wind that has passed through the horizontal axis type wind power generation mechanism 12 passes through the inside of the vertical axis type wind power generation mechanism 11 and rotates the spoke blades 38 provided in the vertical axis type wind power generation mechanism 11, enabling power generation.

[0259] (Other Equipment)

[0260] In order to ensure functioning of these mechanisms, a vertical stabilizer for controlling the direction can be attached to the upper portion of the bell mouth duct 23 of the horizontal axis type wind power generation mechanism 12. That is, when a turntable (not illustrated) is installed on the mount 51, by attaching a stabilizer (not illustrated) to the upper portion of the integrated type wind power generation mechanism, it is possible to directly change the orientation in the horizontal direction by rotating the turntable to face the wind direction. Therefore, it is possible to efficiently generate power.

[0261] (Generator)

[0262] In the wind power generator 1 of the third embodiment of the present disclosure, the generators A40a and A40b are respectively fixed in the vertical axis type wind power generation mechanism 11 and the horizontal axis type wind power generation mechanism 12 using the generator support means. The generators A40a and A40b are respectively directly connected to the windmill rotation shaft 31a and the windmill rotation shaft 31b, and can independently generate power by the rotational forces generated by the blades 321 and 322.

[0263] In this case, it is preferable that the windmill rotation shaft 31a is integrated with and directly connected to a rotation shaft 41a of the generator 40a as in this example. For example, it is preferable that the windmill rotation shaft 31b of the horizontal axis type wind power generation mechanism 12 and the windmill rotation shaft 31a of the vertical axis type wind power generation mechanism 11 be respectively formed of the same rotating shafts as the rotation shafts 41b and 41a of the generator 40b and the generator 40a, or the windmill rotation shaft 31b and the windmill rotation shaft 31a be respectively joined to the rotation shaft 41b of the generator and the rotation shaft 41a of the generator by shaft couplings. By joining with the shaft couplings, it is possible to absorb misalignment and transmit power without applying an extra load to the motor and the windmill.

[0264] Although various generators can be used in the wind power generator 1 of the third embodiment of the present disclosure, it is preferable to use the generator 40 according to the characteristics of the windmill 30 so that the vertical axis type wind power generation mechanism 11 uses a low wind speed generator and the horizontal axis type wind power generation mechanism 12 uses a high wind speed generator.

[0265] In particular, the generator attached to the horizontal axis type wind power generation mechanism 12 preferably uses an alternator, which is an AC generator for a vehicle. Since alternators are widely used in vehicles, ships, and the like, they are easy to handle and maintain, and since there are many rebuilt products, they can contribute to a recycling-oriented society.

[0266] Moreover, although two generators 40 are installed in the example illustrated in FIG. 6, as will be described below, it is also possible to install only one of them and directly connect it to the windmill rotation shaft 31a and the windmill rotation shaft 31b.

[0267] (Windmill Rotation Shaft 31)

[0268] In the third embodiment of the present disclosure, the windmill rotation shaft 31b of the horizontal axis type wind power generation mechanism 12, the generator 40b, the generator 40a, and the windmill rotation shaft 31a of the vertical axis type wind power generation mechanism 11 are formed on the same axis, and two generators, the generator 40b and the generator 40a, are installed.

[0269] Another example of another third embodiment of the present disclosure could be a single generator. That is, one of the generator 40b and the generator 40a can be omitted and the windmill rotation shaft 31b of the horizontal axis type wind power generation mechanism 12, the rotation shaft of the generator, and the windmill rotation shaft 31a of the vertical axis type wind power generation mechanism 11 can be a single rotation shaft. This enables cost reduction and weight reduction.

[0270] (Independent Use)

[0271] The wind power generator 1 of the present disclosure is not limited to use in the integrated type wind power generation mechanism 13, and the portion of the vertical axis type wind power generation mechanism 11 and the portion of the horizontal axis type wind power generation mechanism 12 can also be separated and used independently. However, in order to provide products at lower prices, three types of the integrated type wind power generation mechanism 13, the vertical axis type wind power generation mechanism 11, and the horizontal axis type wind power generation mechanism 12 are prepared, and it is convenient to select one of the types according to the application.

[0272] (Others)

[0273] Since the wind power generator 1 of the present disclosure has a very simple structure and does not require parts such as a brake sensor, the number of parts can be reduced, so that it can be manufactured at low cost.

[0274] (Application Example)

[0275] As an application example of the present disclosure, the integrated type is suitable for a ship or the like because sea breeze can be expected even when the ship is stopped. The horizontal axis type is preferable when it is mounted on an automobile such as a long-distance truck. In addition, the integrated type can be effectively used for vehicles that assume disasters and vehicles used for camping or the like, and the vertical axis type can be effectively used when installing in a place with good wind conditions such as along the coast. However, in either case, each type of wind power generator can be used.

[0276] When using each type independently, it becomes a mechanism to attach the generator 40 to each of the vertical axis type wind power generation mechanism 11 and the horizontal axis type wind power generation mechanism 12.

[0277] Moreover, when a high-performance generator is developed, it is also possible to install and use only the vertical axis type wind power generation mechanism 11 in a truck or the like.

[0278] (Charge Control Mechanism)

[0279] Moreover, a charge control mechanism can be further provided for charging a battery mounted on a moving body or a spare battery for replacement with the electricity generated by the wind power generator of the present disclosure. Such charge control mechanisms include, for example, power generation control system devices. This is a battery device that controls the battery charging by controlling alternator voltage in response to changes in the windmill rotation speed.

[0280] In the power generation control system device, by using a microcomputer to control the voltage generated by the alternator to be lowered when the moving body is moving at a constant speed and to control the generated voltage to be increased when the moving body is decelerating, the load on the windmill due to the alternator power generation can be reduced, enabling efficient power generation.

[0281] (Vertical Connection of Windmill 30)

[0282] When the vertical axis type wind power generation mechanism 11 is used alone, it is effective to connect the vertical axis type windmills 30 in two or three stages in a comb shape as a measure for increasing the amount of power generation. In the present disclosure, since the windmill 30 has a large blade area and a large rotational torque, a form in which one generator 40 is provided for a plurality of windmills 30 is possible.

[0283] (Automatic Attitude Control of Integrated Type Wind Power Generation Mechanism 13)

[0284] By attaching a gas damper and a gas spring to the mount 51 and the wind power generator, the integrated type wind power generator of the present disclosure can automatically control the vertical/horizontal altitude of the integrated type wind power generation mechanism 13.

[0285] For example, by attaching one end of the gas damper to the mount 51 and the other end (rod portion) of the damper to the integrated type wind power generation mechanism 13, it is possible to automatically control the vertical/horizontal attitude of the integrated type wind power generation mechanism 13 according to when the moving body moves or stops.

[0286] Preferably, the gas damper is attached between the mount 51 and the vertical axis type wind power generation mechanism 11.

[0287] That is, first, when the moving body is in a stationary state, a rod of the gas damper is fully extended (in this state, the integrated type wind power generation mechanism 13 is in a vertical state as illustrated in FIG. 6). Then, when the moving body starts traveling, the wind pressure hitting the integrated type wind power generation mechanism 13 increases, and due to this wind pressure, the rod of the gas damper attached to the integrated type wind power generation mechanism 13 is automatically pushed into a damper cylinder and contracted (as a result, the attitude of the integrated type wind power generation mechanism 13 becomes horizontal as illustrated in FIG. 10).

[0288] Then, when the moving body stops traveling, the wind pressure disappears, so the rod of the gas damper rebounds and stretches again, pushing up to raise the integrated type wind power generation mechanism 13 at a tip portion of the rod of the gas damper. As a result, the integrated type wind power generation mechanism 13 returns to the vertical state as illustrated in FIG. 6.

[0289] As the gas damper, for example, a lightweight gas damper used for opening and closing hatchbacks of automobiles is preferably used. A gas spring, an oil damper, or the like can also be used in addition to the gas damper.

[0290] The present disclosure is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
