[0022] According to the present invention, an apparatus for amplifying rotating force of a wind power generator includes a multilayered rack-like frame unit 1100 having layered horizontal frames 1110, vertical frames 1120 provided between the horizontal frames to define space, and a side frame 1130 provided on a side of each horizontal frame.

[0029] A vertical rotating unit 700 includes a horizontal rotating shaft 800 that is coupled to pass through a horizontal-rotating-shaft support 1000 mounted on an upper surface of the side frame to be vertically rotated in conjunction with the central rotating shaft and thereby increase rotating force of the upper horizontal rotating unit, and a vertical rotating wing 720 provided on a central rotating part 710 that is coupled to the horizontal rotating shaft via a horizontal-rotating-shaft passing hole 711.

[0030] Further, a shaft conversion unit 900 is provided to convert a horizontal rotating motion of the central rotating shaft into a vertical rotating motion using the rotating force of the central rotating shaft so as to rotate the vertical rotating unit 700.

[0031] To be more specific, the blade 100 may various shapes and numbers depending on a topographical location where the wind power generator is installed and a power generating capacity and then may be coupled to the upper end of the central rotating shaft 200, as shown in FIG. 1. Preferably, the blade is formed to be curved in one of opposite rotating directions to be easily rotated by wind power.

[0032] As shown in FIG. 6, the upper horizontal rotating unit 300 includes an upper shaft holder 310 that is coupled to an upper surface of the upper fastening plate 400 around the central rotating shaft 200, an upper rotating wing 320 that has on an upper surface thereof a curved downward depressed part 321 to produce ascending air current when the upper horizontal rotating unit 300 is rotated by rotation of the blade 100, a horizontal-rotating-unit magnetic member 330 that is coupled to a magnetic-member inserting hole 322 that is depressed in a side of an end of the upper rotating wing 320; and an upper rotating shaft 340 that is fastened at one side thereof to the upper shaft holder 310 by a coupling pin and is coupled at the other side thereof the upper rotating wing 320, so that the upper rotating wing 320 is opened downwards to be parallel to the horizontal frame by centrifugal force as the blade 100 rotates about the upper shaft holder 310.

[0033] The lower horizontal rotating unit 500 includes a lower shaft holder 510 that is coupled to a lower surface of the lower fastening plate 600 around the central rotating shaft 200, a lower rotating wing 520 that has on a lower surface thereof a curved upward depressed part 521 to increase rotational inertia when the lower horizontal rotating unit 500 is rotated by rotation of the blade 100, a lower rotating shaft 530 that is fastened at one side thereof to the lower shaft holder 510 by a coupling pin and is coupled at the other side thereof the lower rotating wing 520, so that the lower rotating wing is opened upwards to be parallel to the horizontal frame by centrifugal force as the blade 100 rotates about the lower shaft holder 510.

[0034] As shown in FIG. 5A, the shaft conversion unit 900 includes a belt pulley 930 that is coupled to a lower end of the central rotating shaft 200, a vertical conversion shaft 910 that is provided to pass through the side frame to be parallel to the central rotating shaft, a belt pulley that is provided on a lower end of the vertical conversion shaft to correspond to rotation of the belt pulley of the central rotating shaft, a rotary belt 940 that connects both the belt pulleys to each other and transmits rotating force of the central rotating shaft, and a shaft conversion gear 920 that is formed on an upper end of the vertical conversion shaft 910. The vertical rotating unit coupled to the horizontal rotating shaft 800 performs vertical movement in conjunction with the central rotating shaft. The horizontal rotating shaft has on an end thereof a horizontal-rotating-shaft change gear 820 to engage with the shaft conversion gear and thereby to convert horizontal rotation into vertical rotating motion, and is installed to pass through the horizontal-rotating-shaft support 1000 and.

[0035] Further, as shown in FIG. 5B, the shaft conversion unit includes a belt pulley 930 that is provided on a lower end of the central rotating shaft, a rotary gear belt 950 that is provided between the belt pulley 930 and a horizontal-rotating-shaft rotary gear to transmit rotating force of the central rotating shaft to the horizontal-rotating-shaft rotary gear 830 that is formed on an outer surface of an end of the horizontal rotating shaft passing through the horizontal-rotating-shaft support 1000, with teeth being formed on a side thereof, and a belt rotating gear 970 and a belt rotating part 980 that are rotatably coupled to two rotary-gear-belt supports 960, respectively, by a fastening pin between the belt pulley and the horizontal-rotating-shaft rotary gear to smoothly transmit rotating force of the rotary gear belt. The rotating force of the central rotating shaft transmitted by the rotary gear belt is transmitted to the horizontal rotating shaft, so that the vertical rotating unit coupled to the horizontal rotating shaft performs vertical movement in conjunction with the central rotating shaft.

[0036] The horizontal-rotating-shaft support 1000 includes a plate-shaped support plate 1010 that is fastened to an upper surface of the horizontal frame of the frame unit 1100, and has a vertical-conversion-shaft passing hole 1011 perforated on a side of an upper surface thereof such that the vertical conversion shaft 910 or the rotary gear belt of the shaft conversion unit 900 passes therethrough to transmit power, and a protruding support 1020 that protrudes upwards from an upper surface of the support plate 1010 to adjust a vertical position of the vertical rotating unit 700 and has a horizontal-rotating-shaft inserting hole 1021 that is penetrated into a center of an upper portion of the support plate to allow the horizontal rotating shaft 800 to be inserted therein. That is, the horizontal rotating shaft is rotatably inserted into the horizontal-rotating-shaft inserting hole of the protruding support to convert the horizontal rotating motion into the vertical rotating motion by the shaft conversion unit.

[0037] As shown in FIG. 7, the vertical rotating unit 700 includes a central rotating part 710 that has a horizontal-rotating-shaft passing hole 711 penetrated at a center thereof to allow the vertical rotating unit 700 to be inserted into the horizontal rotating shaft 800, at least one vertical rotating wing 720 having on a side thereof a magnetic-member coupler 721 through which a vertical-rotating-unit magnetic member 730 is coupled thereto, to continuously rotate the upper horizontal rotating unit(300 even when the blade 100 rotates at low speed due to a lack of wind power and simultaneously to double rotating speed of the upper horizontal rotating unit 300 when the blade 100 rotates at high speed, thus allowing the rotating force to be transmitted to the central rotating shaft 200; and a position adjusting shaft 740 connecting the vertical rotating wing 720 with the central rotating part such that a position of the vertical rotating wing 720 corresponds to a position of the upper rotating wing 320 provided on the upper horizontal rotating unit 300.

[0038] The central rotating part and the position adjusting shaft 740 are coupled with a hinge-part rotating shaft 760 formed on the central rotating part, via an “U”-shaped hinge part 750. As shown in FIG. 9, the position adjusting shaft 740 is coupled, via a fastening pin, to an “U”-shaped groove to be rotatable leftwards and rightwards, and the other side of the hinge part is coupled, via a fastening pin, to an “U”-shaped groove formed on an end of the hinge-part rotating shaft to be rotatable upwards and downwards. Therefore, the vertical rotating wing is manufactured to be movable upwards, downwards, leftwards and rightwards. Further, a foldable limiting part 770 is provided between neighboring hinge-part rotating shafts 760 to limit a moving radius of the position adjusting shaft 740. Thus, the position adjusting shaft 740 is folded within a predetermined radius by repulsive force between the vertical-rotating-unit magnetic member 730 fastened to a side of the vertical rotating wing 720 and the horizontal-rotating-unit magnetic member 330 coupled to a side of an end of the upper rotating wing 320, thus preventing the position adjusting shaft 740 or the vertical rotating wing 720 from being deformed or damaged. Preferably, when the vertical-rotating-unit magnetic member 730 is fastened to the magnetic-member coupling part 721, they are fastened to each other such that the same poles of the vertical-rotating-unit magnetic member and the horizontal-rotating-unit magnetic member 330 provided on the upper rotating wing 320 face each other.

[0039] Further, in order to allow the central rotating shaft and the horizontal rotating shaft to be smoothly rotated, bearings 1200 may be provided between the central rotating shaft, the upper fastening plate, the lower fastening plate, the frame unit and the horizontal rotating shaft and the horizontal rotation support.

[0040] According to an embodiment, the blade 100 provided on an upper end of the apparatus for amplifying the rotating force of the wind power generator rotates in a direction by wind power, thus causing the central rotating shaft 200 to be rotated in one direction. As the central rotating shaft 200 rotates, the upper rotating wing 320 and the upper rotating shaft 340 and the lower rotating wing 520 and the lower rotating shaft 530, which are coupled to the upper surfaces of the upper fastening plate 400 and the lower fastening plate 600 around the central rotating shaft 200 by the upper shaft holder 310 and the lower shaft holder 510, may be rotatably spread downwards or upwards by centrifugal force about the upper shaft holder 310 and the lower shaft holder 510. At this time, ascending air current is produced by the downward depressed part 321 that is curvedly depressed on the upper surface of the upper rotating wing 320 that is rotatably spread downwards, as shown in FIG. 10, and then the ascending air current is transmitted to a lower portion of the blade 100, thus increasing the rotating speed of the blade 100. Meanwhile, rotational inertia is increased by the upward depressed part 521 that is curvedly depressed on the lower surface of the lower rotating wing 520 that is rotatably spread upwards, thus increasing the rotating force of the central rotating shaft 200 and enhancing power generating efficiency.

[0041] When the central rotating shaft 200 is rotated by the rotation of the blade 100, as shown in FIGS. 5A and 5B, the horizontal rotating shaft 800 and the vertical rotating unit 700 inserted into the horizontal rotating shaft 800 may also rotate in response to the rotation of the central rotating shaft 200 by the shaft conversion unit 900. In this case, as shown in the detailed view of FIG. 11, the rotating speed of the upper rotating wing 320 may be doubled by the repulsive force between the vertical-rotating-unit magnetic member 730 coupled to the vertical rotating wing 720 of the vertical rotating unit 700 and the horizontal-rotating-unit magnetic member 330 fastened to the upper rotating wing 320 of the upper horizontal rotating unit 300, which are arranged such that their same poles face each other. Even when the blade 100 rotates at low speed due to a lack of wind power acting on the blade 100, the upper rotating wing 320 may be continuously rotated by the repulsive force between the vertical-rotating-unit magnetic member 730 and the horizontal-rotating-unit magnetic member 330, thus allowing power to be continuously generated. Further, when the upper rotating wing 320 meets the vertical rotating wing 720, as shown in FIG. 9, the position adjusting shaft 740 is folded within a predetermined radius by the hinge part 750 and the hinge-part rotating shaft 760, thus preventing the vertical rotating wing 720 or the position adjusting shaft 740 from being damaged by the repulsive force between the horizontal-rotating-unit magnetic member 330 and the vertical-rotating-unit magnetic member 730. The foldable limiting part 770 protruding outwards from the outer surface of the central rotating part 710 of the vertical rotating unit 700 prevents the position adjusting shaft 740 from being excessively folded, thus preventing the repulsive force between the horizontal-rotating-unit magnetic member 330 and the vertical-rotating-unit magnetic member 730 from being reduced.

[0042] As described above, the present invention provide an apparatus for amplifying rotating force of a wind power generator, in which an upper horizontal rotating unit and a lower horizontal rotating unit that are inserted into the same rotating shaft as a blade rotatable by wind power and are provided under the blade are rotated by the rotation of the blade, so that ascending air current produced in the upper horizontal rotating unit is transmitted to the blade and thereby the rotating speed of the blade is increased and rotational inertia increased by the lower horizontal rotating unit causes the rotating force of the rotating shaft to be increased, thus allowing the wind power generator to efficiently generate power.

[0043] Further, the present invention provide an apparatus for amplifying rotating force of a wind power generator, in which magnetic members are inserted into ends of an upper horizontal rotating unit and a vertical rotating unit that is rotatable by the rotation of the upper horizontal rotating unit such that the same poles are opposite to each other, so that a blade is continuously rotated by repulsive force between the magnetic members even when the blade rotates at low speed due to a lack of wind power acting on the blade, thus enabling continuous power generation, and simultaneously the rotating speed of the blade may be doubled when the blade rotates at high speed.

[0044] While the invention has been shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

[0045] Therefore, the scope of the invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present invention.
