Separated-Wave Powered Electricity Gennerator

Abstract

This invention is a method in which large waves are separated from a floating platform unit by using a partition plate unit so that the floating platform unit enclosed by the partition plate unit is in a state of almost no wave. These large waves outside the partition plate unit are to move many floating ball units up and down so that the racks provided on each of the floating ball units are capable of rotating the power gears extending from the floating platform unit, and the rotational forces of power gears are regulated through ratchets and consolidated to produce a single direction rotating power, and then to drive external generators. The racks on the floating ball units and the power gears on the floating platform unit are pulled together by using springs. The resilient force of the two springs simultaneously helps the rack's up and down in smooth reciprocating motion. Then the power gears directly and indirectly drive the multiple coaxial gear to output a single-direction spinning force to drive the external generators. The invention has the advantages of super high-efficiency, simple structure, easy to set up, able to be fixed or not fixed on the shore, and able to be set up offshore, and the size of the entire mechanism can be easily extended or adjusted linearly in terms of power demand. It can fully utilize the available sea area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0036] This invention is a separated-wave powered electricity generator. Basically, it comprises many pontoon units (10), one floating platform unit (20), and one partition plate unit (30). Referring to FIG. 1 through FIG. 16B, one of the embodiment examples is listed below:

[0037] Referring to FIG. 1-5, the floating platform unit (20) comprises a long and large floating platform (210) above which a supporting frame (220) is set up. This floating platform (210) is to lift up the supporting flame (220) above sea level. A central rotation shaft (221) is set up above the supporting flame (220). At each side of the central rotation shaft (221), a sideways rotation shaft (222) is set up. On each of the sideways rotation shaft (222), many dynamic gears (223) are set up. Each of the dynamic gear (223) is corresponding to one pontoon unit (10). Referring to FIG. 3, on dynamic gear's (223) right-hand side (as defined in FIG. 3.) is a ratchet gear (224) is set up. Corresponding to this ratchet gear (224) a passive gear (225) is set up on central rotation shaft (221). This ratchet gear (224) and the corresponding passive gear (225) are connected with cog belt or chain (226). This dynamic gear (223) also meshes a direction-reverse gear which is set up on the direction-reverse rotation shaft which is set up on the supporting frame (220). At a side of the direction-reverse gear, a ratchet gear (224) is also set up. This ratchet gear (224) also connects to a passive gear (225) on the central rotation shaft (221) with cog belt or chain (226). At both ends of the central rotation shaft (221), two electric generators (370) are connected. Thereby, passive gears' (225) revolution drives central rotation shaft (221) and then to drive electric generators (370) to generate electricity. Besides, as shown in FIG. 12A, the sideways rotation shaft (222) has to be equipped with shaft sleeves (223(a)) in order to fit in with dynamic gear's (223) motion.

[0038] Referring to FIG. 3 again, the previously stated right-hand side (as defined in FIG. 3) ratchet gear (224) can rotate when pontoon rises and keep motionless when pontoon sinks. In order to generate electricity when pontoon either rises or sinks, this dynamic gear (223) also meshes a direction-reverse gear (22a) which is set up on direction-reverse axis (22b) erected on supporting flame (220). At the left-hand side, (as defined in FIG. 3) of this direction-reverse gear (22a) also set up a ratchet gear (224) on direction-reverse axis (22b). Corresponding to this ratchet gear (224) a passive gear (225) on central rotation shaft (221) is set up. This ratchet gear (224) also connects the corresponding passive gear with cog belt or chain (226). This ratchet gear (224) rotates as pontoon (110) sink and keep motionless as pontoon rise.

[0039] As shown in FIG. 2, the pontoon unit (10) is set up at one side of the floating platform unit (20). This pontoon unit (10) and the floating platform unit (20) are separated by the partition plate unit (30). As shown in FIG. 3-5, the pontoon unit (10) includes a pontoon (10) above which is covered with an arched plate (120). Above this arched plate (120), a frame (130) is set up. At this frame's (130) side which is facing floating platform unit (20), a vertical gear rack (131) is set up. This gear rack (131) meshes the dynamic gear (223). As shown in FIG. 12 and FIG. 13, when waves move pontoon (110) up and down, the gear rack (131) goes up and down. Along with gear rack's (131) going up and down, the dynamic gear (223) spin either clockwise or counterclockwise. This dynamic gear (223) directly or indirectly turn two sides' ratchet gear (224) at two reversed directions. Through passive gears, these two directional spinning forces are then consolidated into a single direction to drive the central rotation shaft (221) then drive the electric generator (370); therefore, as waves go either up or down, power produced. Besides, the arched plate (120) is to absorb more wave's thrust power to enhance the energy absorbing efficiency. In an embodiment example, the sideways rotation shaft (222) and direction-reverse shaft (22b) are fastened without spinning motion.

[0040] As shown in FIGS. 3, 10, 11, and 11A, beside dynamic gear (223), two buckle plates (227) stretch out. These two buckle plates connect two springs which pull the dynamic gear (223) toward the flame in order to mesh the gear rack (131), also when the flame rises or sinks (as shown in FIGS. 14 and 15), one of the two springs can store the mechanic energy so that when the flame goes back in the opposite direction the stored energy can be released. Hence these two springs make the gear rack (131) move smoothly. Because this mechanism absorb sea wave energy when gear rack (131) goes either up or down, therefore it works in better efficiency and smoothness than those designs which work only when waves go up or down. In an embodiment example, at the ends closer to dynamic gear, these two springs (132) may use buckles (133) to connect buckle plates (227) for easy installation and replacement. Besides, this invention's spring (132) design also brings some special effect as following:

[0041] When this separated-wave powered electricity generator is installed in sea area or beside seashore, the height of flame (130) can be made equal to or larger than the maximum wave height (from crest to trough) of the waves around that area. However, in case of big waves caused by gale, on the way of the waves' going up, the flame is brought up so high that the flame's (130) lower beam is blocked by the buckle plates (227) but the flame (130) can keep going up until the spring tension is equal to the waves' thrusting force. Then the spring tension produce downward force to make the flame (130) go down smoothly; Similarly, the spring tension produce upward force to make the flame (130) go up smoothly when the big wave bring the flame (130) going down and its upper beam is blocked by the buckle plates (227).

[0042] As shown in FIG. 12A, on sideways rotation axis (223), the dynamic rotation gear (223) and the ratchet gear (224), each has to carry a shaft sleeve (223(a)) to run smoothly on sideways rotation axis (223) which does not spin by itself; On direction-reverse shaft (22b), the direction reverse gear (22a) and the ratchet gear (224) each has to carry a shaft sleeve (223(a)) to run smoothly on direction-reverse shaft (22b) which does not spin by itself.

[0043] As shown in FIGS. 12B and 12C, on passive gear (225), its lateral can be equipped with a coil spring (132(a)). When the passive gear (225) is not turning, the coil spring may be loosen. As the passive gear's (225) spinning speed is less than the spinning speed of the central rotation axis (221) the coil spring (132(a)) gradually tighten up to store the energy conveyed through pontoon; As the passive gear's (225) speed achieve that of the central rotation axis (221) this stored energy can be applied on the central rotation axis (221). Besides, other gears can be equipped with coil spring (132(a)) but there is no restriction on this issue.

[0044] Depending on the waves' undulation strength, the length of springs (132) and the length of gear racks (131) can be adjusted to monitor the activity scope of pontoons (10).

[0045] In an embodiment example, as shown in FIG. 3,5,7,8, on flame 130 lateral's four corners, four supporting rods (134) extend to above the floating platform's 20 supporting frame (220). On each end of these supporting rods (134), a link slide block (135) is attached (or embodied with bearing style). On the supporting flame (220), corresponding to the link slide block (135), a sliding rail (228) is set up. With this sliding rail's (228) constraint, the flame (130) can go up and down relative to the supporting rlame (220). In another embodiment example, the bearing style means that at the center of the sliding rail (228) there is a rail (138). Two bearing pulleys attached at the end of the four support rods (134) can slide on the two sides of the rail (138).

[0046] As shown in FIG. 1,2,5,6, the profile of the partition plate unit (30) is shaped like a box without bottom and cover. This partition plate unit (30) encloses the floating platform unit (20) but only allows the outer rotation shaft' (222) connection bar (229) penetrate the partition plate unit (30) in order to contact the pontoon unit (10); Two terminals of this partition plate unit (30) are equipped with two floating boxes (360) to carry the weight of the partition plate unit (30). Under these floating boxes there may connect ropes (310). The other end of these ropes (310) then may be connected with heavy chunks (320) such as stone or iron chunks which are to be sunk to the seabed in order to hold the entire machinery not to be drift away. Each rope (310) can measure an equal distance from floating box' (360) connection point and then connect it to an iron ball (350). These four iron balls can equilibrate the entire machinery.

[0047] The length of floating box (360) can be adjust according to the specific requirement. In an embodiment example, as shown on FIG. 2A, the length of the floating box (360) is close to the length of the partition plate unit (30). Hence if we connect the two endpoints of these two floating boxes (360) with dot lines, these four dot lines forms a square shape which further equilibrates the entire machinery. Besides, the two ends of separated-wave electricity generator's central rotation shaft (221) may connect to external electric generator(s) (370) which may connect(s) to cables (371). Two or many external electric generators (370) may be connected with bus bar. If many separated-wave powered electricity generators are connected together, the whole group may be even more equilibrated than an isolated one.

[0048] The partition plate unit (30) is to enclose the floating platform unit (20) from outside waves. This makes floating platform unit (20) stays in an almost waveless state while multiple pontoon units (10) stay among big waves. The bigger waves there are, the higher efficiency this separated-wave powered electricity generator performs. As for other methods using gear rack to turn gear, because waves are not separated, two passive element, the gear rack and the gear, are bearing the waves' force in quite similar direction and dynamic, hence produce only low efficiency output.

[0049] As shown on FIG. 7,8,9, the partition plate unit's (30) open channel (330) is to allow pontoon unit's (10) supporting rod (134) go up and down freely. But in order not to allow seawater seeps into the floating platform unit (20) through the partition plate unit's (30) open channel (330), the supporting rod (134) carries a barrier strip (136) inside the partition plate unit (30) and the barrier strip (136) is to press close to the partition plate unit (30). This barrier strip's (136) length is longer than the length of the open channel (330) for assuring that even the pontoon unit (10) moves in its maximum distance, the partition plate unit (30) still can block waves.

[0050] On partition plate unit (30), at the place where connection bar (229), cog belt or chain (226), and central rotation axis (221) penetrate through partition plate unit (30), open channels (330) are set up. Inside the partition plate unit (30) and pressing close to each of the open channels (330), a barrier strip (136) is set up on the supporting flame (220) of the floating platform unit (20). On each of the barrier strip (136), at where the connection bar (229), cog belt or chain (226), and central rotation axis (221) penetrate through, a hole (137) is set up. Thus when relative motion happens between pontoon unit (10) and partition plate unit (30), floating platform unit (20) and partition plate unit (30), each of the barrier strip (136) can cover each of the open channels (330). Each barrier strip (136) is made longer than each of the open channels (330) to ensure partition plate unit's (30) seawater-blocking function.

[0051] Besides, in order to avoid the collision between floating platform unit (20) and partition plate unit (30), at partition plate unit's (30) two end sides which are facing the floating platform unit's (20) end sides, also sliding rails (228) may be set up in order to allow the four link slide blocks (135) of the four supporting rods (134) which stretch out from the supporting flame of the floating platform unit to slide up and down freely inside the sliding rails (228). (No figure is provided.)

[0052] FIG. 16A illustrates the operation of an existing technique, crank-connecting mechanism, one of the point absorbing styles: Cranks are extended from the body's two sides to sea surface. At cranks' base ends there are equipped with floating plates which go up and down as the waves rise and fall thus it makes the cranks swing to rotate the central axes to generate electricity. Tremendous engineering works has to be done on this mechanism due to its huge structure and the hard work for fastening the body in seabed. The crank's swing angle is less than 10.sup.0 thus the output efficiency is low. Referring to FIG. 16B, in this invention and by contrast, dynamic gears' 223 spin continually as the gear racks 131 go up and down during the waves rise and fall and the resulted spinning angle is way higher than 10.sup.0, hence it produce way higher efficiency than that of crank-connecting mechanism.

[0053] The electricity generated by electric generator set (370) can be conveyed or deposited by the following methods: hydrogen energy transferring, electrified wire netting, supercapacitors, battery, submarine cable, etc.

[0054] Above is one of the embodiment examples and not to be used to confine the scope of this invention's application. Besides, a simple model for testing was made and by using this model, a film which successfully demonstrates the fundamental essence of this invention is available.
