Description

Technical Field

[0001] This invention relates to a wave generator structure, and more particularly to a multi-directional drive wave generator system that integrates multi-directional drive power generation technology to achieve high-efficiency power generation. Background Technology

[0002] Currently, the wave power generation technology developed by various countries mainly involves building power plants on the coast or offshore, installing controllers and generators within the power plants, and connecting rods extending into the sea to install a float. The rise and fall of the float by the waves causes the connecting rods to swing, thereby transferring kinetic energy to the generator to produce electricity. However, the float is limited to swinging within a specific range due to the connecting rod mechanism. Wave kinetic energy exceeding this range cannot be converted into electrical energy. Furthermore, the float's descent distance is only the velocity of its own weight, resulting in low power generation. Moreover, waves are affected by weather and tides, leading to unstable power generation. Therefore, the obvious drawback of conventional wave power generation technology is its low power generation efficiency. Building more generator sets would significantly increase costs, which is not economically viable. As a result, wave power generation cannot be widely adopted and promoted. The above-mentioned shortcomings are the technical problems that this invention aims to improve.

[0003] In view of this, based on the inventor's many years of experience in manufacturing, developing and designing related products, and after detailed design and careful evaluation of the above objectives, the inventor has finally arrived at an invention that is truly practical. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-directional driven wave power generation system to address the above-mentioned deficiencies in the existing technology.

[0005] The multi-directional driven wave power generation system provided by the present invention includes a first generator connected to a bidirectional drive assembly via a rotating shaft, and an input gear connected to the bidirectional drive assembly. The input gear meshes with a rack and is fixed to a housing via the rack. A second generator is connected to a universal rotating element via a central shaft, and a first bevel gear is connected to the universal rotating element and disposed within the housing. A float has a through hole in its center, and at least one blade is installed in the through hole. A second bevel gear extends axially from the blade and meshes with the first bevel gear within the housing. The float moves with the rise and fall of the waves, causing the rack to reciprocate linearly. The first generator is driven sequentially by the input gear and the bidirectional drive assembly. Simultaneously, the waves pass through the through hole of the float and drive the blade. The second generator is driven sequentially by the second bevel gear, the first bevel gear, and the universal rotating element.

[0006] The bidirectional drive assembly includes a driven shaft coaxial with the shaft of the first generator, and the driven shaft is equipped with a driven gear and a driven pulley. A one-way ratchet is installed between the driven gear, the driven pulley and the driven shaft. The bidirectional drive assembly includes a drive shaft coaxial with the input gear, and the drive shaft is equipped with a drive gear and a drive pulley. The drive gear and the driven gear mesh with each other, and a belt is sleeved between the drive pulley and the driven pulley.

[0007] The bidirectional drive assembly includes a secondary shaft coaxial with the shaft of the first generator, and the secondary shaft is equipped with a first wheel and a second wheel. A one-way bearing is installed between the first wheel, the second wheel and the secondary shaft. The bidirectional drive assembly includes a main shaft coaxial with the input gear, and the main shaft is fixedly fitted with a third wheel and idling fitted with a fourth wheel. The main shaft and the secondary shaft are arranged in a cross configuration, and an annular belt is wound around the first wheel, the second wheel, the third wheel and the fourth wheel.

[0008] The first generator is connected to a turbine drive assembly via a rotating shaft, and a pneumatic cylinder is connected to the turbine drive assembly. A piston is installed inside the pneumatic cylinder, and the piston extends out of the pneumatic cylinder and is fixed to a housing by a push rod. The turbine drive assembly includes an air turbine and an air storage tank. The air turbine is connected to the rotating shaft of the first generator, and the air storage tank is connected to both ends of the pneumatic cylinder by two one-way valve pipes, so that air can be injected into the air storage tank during the reciprocating stroke of the pneumatic cylinder. An air supply pipe is connected between the air turbine and the air storage tank, and compressed air drives the air turbine to rotate and drive the first generator to generate electricity. The above mechanism can also be changed to inject liquid, and the circulating liquid drives the liquid turbine, which can also achieve the same purpose of power generation.

[0009] The float has a conical surface on the side facing the waves that is recessed toward the through hole, and the conical surface guides the waves into the through hole.

[0010] The universal rotating element includes at least one universal joint and one spline shaft. The universal joint has the functions of transmitting rotational kinetic energy and allowing the universal rotating element to move up and down, and the spline shaft has the functions of transmitting rotational kinetic energy and allowing the universal rotating element to extend and retract back and forth.

[0011] The universal rotating element is a constant velocity universal joint, which includes an input universal joint, an output universal joint, and a drive shaft. One end of the drive shaft passes through the input universal joint and forms a displacement head within the input universal joint. The other end of the drive shaft passes through the output universal joint and forms a rotation head within the output universal joint. The input universal joint has the functions of transmitting rotational kinetic energy and allowing the universal rotating element to extend and retract back and forth, and the output universal joint has the functions of transmitting rotational kinetic energy and allowing the universal rotating element to move up and down.

[0012] The universal rotating element is provided with at least one flexible shaft. One end of the flexible shaft is connected to the second generator, and the other end of the flexible shaft is connected to the first bevel gear. The flexible shaft has the function of transmitting rotational kinetic energy and also allows for forward and backward extension and up and down twisting.

[0013] The first generator's shaft and the second generator's central shaft are both connected to an inertial flywheel.

[0014] The main objective of this invention is that the float moves with the waves, causing the rack to reciprocate linearly. The first generator is driven sequentially by the input gear and the bidirectional drive assembly, thereby generating a lifting and lowering drive power generation effect through the float. Simultaneously, the waves pass through the through hole of the float and drive the blade fan. The second generator is driven sequentially by the second bevel gear, the first bevel gear, and the universal rotating element, thereby generating a rotation drive power generation effect through the float. This integrates multidirectional drive power generation technology to achieve high-efficiency power generation.

[0077] To enable your review committee to have a better understanding of the purpose, features, and effects of this invention, the following detailed description is provided in conjunction with the accompanying drawings:

[0078] First, please let Figure 1 As shown, a multi-directional driven wave power generation system includes: a first generator 10, a bidirectional drive assembly 20, a second generator 30, a universal rotating element 40, and a float 50. The first generator 10 is connected to the bidirectional drive assembly 20 via a rotating shaft 101, and an input gear 11 is connected to the bidirectional drive assembly 20. The input gear 11 meshes with a rack 12, and the rack 12 is fixed to a housing 13. The bidirectional drive assembly 20 includes a driven shaft 21 coaxial with the rotating shaft 101 of the first generator 10, and the driven shaft 21 is equipped with a driven gear. The input gear 11 has a driven gear 211 and a driven pulley 212. A one-way ratchet 213 is installed between the driven gear 211, the driven pulley 212, and the driven shaft 21. Both ratchet 213 rotate clockwise (undriven) and counterclockwise (driven). The bidirectional drive assembly 20 also includes a drive shaft 22 coaxial with the input gear 11. The drive shaft 22 is equipped with a drive gear 221 and a drive pulley 222. The drive gear 221 meshes with the driven gear 211. A belt body 2 is fitted between the drive pulley 222 and the driven pulley 212. 23. A second generator 30 is connected to a universal rotating element 40 via a central shaft 301, and a first bevel gear 31 is connected to the universal rotating element 40. The first bevel gear 31 is disposed within the housing 13. A float 50 has a through hole 51 extending through its center, and at least one blade 52 is installed within the through hole 51. A second bevel gear 53 extends axially from the blade 52 and meshes with the first bevel gear 31 within the housing 13. The float 50 has a conical surface 54 recessed towards the through hole 51 on the side facing the waves, and the conical surface 54 guides the waves. Waves flow into the through hole 51. As the float 50 rises and falls with the waves, it moves the rack 12 to form a reciprocating linear displacement. The input gear 11 and the bidirectional drive assembly 20 sequentially drive the first generator 10, thereby generating a lifting and lowering drive power generation effect through the float 50. At the same time, the waves pass through the through hole 51 of the float 50 and drive the blade fan 52. The second bevel gear 53, the first bevel gear 31 and the universal rotating element 40 sequentially drive the second generator 30, thereby generating a rotation drive power generation effect through the float 50. This integrates multi-directional drive power generation technology to achieve high-efficiency power generation.

[0079] To further explain its action, please refer to [the following text is incomplete and requires further context]. Figure 2As shown, the density of the float 50 is less than that of seawater, meaning it can float normally on the sea surface and rise and fall with the waves. When the float 50 rises, it will push the shell 13 and the rack 12 to rise synchronously, and the rack 12 will drive the input gear 11 to rotate counterclockwise, which in turn... Figure 3 As shown, the driving gear 221 and driving pulley 222 of the bidirectional drive assembly 20 rotate counterclockwise synchronously with the input gear 11. At this time, the driven gear 211 meshing with the driving gear 221 rotates clockwise, and the driven shaft 21 is not driven due to the idle rotation of the one-way ratchet 213. The driving pulley 222 drives the driven pulley 212 to rotate counterclockwise with the belt body 223, and at the same time, the one-way ratchet 213 drives the driven shaft 21 to rotate counterclockwise, thereby transferring rotational kinetic energy to the first generator 10 to generate electricity. The shaft 101 of the first generator 10 is connected to an inertial flywheel 14, and the inertial rotation of the inertial flywheel 14 forms the stable rotation of the first generator 10. Similarly, ... Figure 4 As shown, when the float 50 descends, it will push the housing 13 and the rack 12 to descend synchronously. The rack 12 drives the input gear 11 to rotate clockwise. The driving gear 221 and driving pulley 222 of the bidirectional drive assembly 20 rotate clockwise synchronously with the input gear 11. At this time, the driven gear 211 meshing with the driving gear 221 rotates counterclockwise. Therefore, the one-way ratchet 213 can drive the driven shaft 21, thereby transferring rotational kinetic energy to the first generator 10 to generate electricity. The driving pulley 222 drives the driven pulley 212 to rotate clockwise with the belt body 223, allowing the one-way ratchet 213 to idle without driving the driven shaft 21. In summary, the float 50 can drive the first generator 10 to generate electricity during both the rising and falling processes, thereby effectively improving its power generation efficiency.

[0080] For example Figure 2As shown, in one embodiment of the universal rotating element 40, the universal rotating element 40 includes at least one universal joint 41 and a spline shaft 42. The universal joint 41 serves to transmit rotational kinetic energy and allow the universal rotating element 40 to move vertically, while the spline shaft 42 serves to transmit rotational kinetic energy and allow the universal rotating element 40 to extend and retract. That is, as the float 50 rises, the waves will push upwards through the through hole 51, and the thrust can drive the blade 52 to rotate. The rotation of the blade 52 is linked to the second bevel gear 53, and the second bevel gear 53 drives the first bevel gear. The first bevel gear 31 is connected to the second generator 30 by the universal joint 41 and the spline shaft 42. The universal joint 41 and the spline shaft 42 do not affect the first bevel gear 31 from transmitting rotational dynamics to the second generator 30 for power generation. At the same time, the universal joint 41 allows the first bevel gear 31 to move up and down, and the spline shaft 42 allows the universal rotating element 40 to extend and retract back and forth, thereby integrating multi-directional power generation functions that combine reciprocating displacement and rotation. The second generator 30 has a central shaft 301 connected to an inertial flywheel 34. The inertial rotation of the flywheel 34 forms the stable rotation of the second generator 30. Furthermore, the float 50 is limited by the effective stroke of the rack 12. When the float 50 rises to its maximum height, the waves can no longer push the float 50. At this time, the rising potential energy of the waves increases the water pressure and flow velocity of the seawater flowing through the through hole 51, which increases the rotational speed of the blade 52. This allows the potential energy of the waves exceeding the maximum rising height of the float 50 to be effectively utilized, thereby further improving its power generation efficiency. In addition, the float 50 has a conical surface 54 that is recessed towards the through hole 51 on the side facing the waves. The conical surface 54 helps to guide the waves into the through hole 51, so that the waves can be concentrated on the blade 52, thereby also improving its power generation efficiency.

[0081] Another embodiment of the bidirectional drive component 20, please refer to... Figure 5 , Figure 6 and Figure 7As shown, the bidirectional drive assembly 20 includes a secondary shaft 23 coaxial with the shaft 101 of the first generator 10. The secondary shaft 23 is equipped with a first rotating wheel 231 and a second rotating wheel 232. A one-way bearing 233 is installed between the first rotating wheel 231, the second rotating wheel 232, and the secondary shaft 23. Both one-way bearings 233 rotate clockwise in a non-driven state and counterclockwise in a driven state. The bidirectional drive assembly 20 includes a secondary shaft 23 coaxial with the input gear. A main shaft 24 of the gear 11 is fixedly fitted with a third rotating wheel 241 and an idler rotating wheel 242. The main shaft 24 and the auxiliary shaft 23 are arranged in a crisscross pattern. An annular belt 25 is wound around the first rotating wheel 231, the second rotating wheel 232, the third rotating wheel 241, and the fourth rotating wheel 242. During actual operation, when the rack 12 drives the input gear 11 to rotate clockwise, the main shaft 24 and the third rotating wheel 241 will rotate together... The input gear 11 rotates clockwise, while the fourth wheel 242 is not driven by the main shaft 24. The third wheel 241 drives the annular belt 25, causing the annular belt 25 to rotate simultaneously with the first wheel 231, the second wheel 232, and the fourth wheel 242. The second wheel 232 rotates clockwise, in which case it cannot drive the one-way bearing 233 and the countershaft 23. The first wheel 231 rotates counterclockwise and can drive the one-way bearing 233. The bearing 233 drives the secondary shaft 23, thereby driving the first generator 10 to generate electricity. Conversely, the counterclockwise rotating third wheel 241 drives the first wheel 231 to rotate clockwise and the second wheel 232 to rotate counterclockwise. The first wheel 231 cannot drive the secondary shaft 23, while the second wheel 232 drives the first generator 10 to generate electricity through the secondary shaft 23. This allows for effective power generation during both rising and falling waves, thereby increasing the power output.

[0082] Another embodiment of the universal rotating element 40, please refer to... Figure 8 and Figure 9As shown, the universal rotating element 40 is a constant velocity joint (CV joint), which includes an input universal joint 43, an output universal joint 44, and a drive shaft 45. One end of the drive shaft 45 passes through the input universal joint 43, and a displacement head 451 is formed within the input universal joint 43. The other end of the drive shaft 45 passes through the output universal joint 44, and a rotation head 452 is formed within the output universal joint 44. The displacement head 451 can move back and forth along the input universal joint 43, and the rotation head 452 can rotate along the output universal joint 44. That is, the input universal joint 43 has the functions of transmitting rotational kinetic energy and allowing the universal rotating element 40 to extend and retract back and forth, and the output universal joint 44 has the functions of transmitting rotational kinetic energy and allowing the universal rotating element 40 to move up and down. This integrates a multi-directional power generation function that combines reciprocating displacement and rotation.

[0083] Another embodiment of the universal rotating element 40 is described by [the following text is missing from the original] Figure 10 As shown, the universal rotating element 40 is provided with at least one flexible shaft 46. One end of the flexible shaft 46 is connected to the second generator 30, and the other end of the flexible shaft 46 is connected to the first bevel gear 31. Accordingly, when the first bevel gear 31 is driven to rotate, the flexible shaft 46 will be able to rotate synchronously to drive the second generator 30. That is, the flexible shaft 46 has the function of transmitting rotational kinetic energy. In addition, the flexible shaft 46 also has the function of allowing forward and backward extension and up and down swaying, thereby integrating multi-directional power generation functions that combine reciprocating displacement and rotation.

[0084] Another embodiment of the present invention, please refer to... Figure 11As shown, the first generator 10 is connected to a turbine drive assembly 60 via a rotating shaft 101, and a pneumatic cylinder 61 is connected to the turbine drive assembly 60. A piston 62 is installed inside the pneumatic cylinder 61, and the piston 62 extends out of the pneumatic cylinder 61 and is fixed to a housing 13 by a push rod 621. The turbine drive assembly 60 includes an air turbine 63 and an air storage tank 64. The air turbine 63 is connected to the rotating shaft 101 of the first generator 10. The air storage tank 64 is connected to both ends of the pneumatic cylinder 61 via two one-way valve pipes 641. The float 50 drives the push rod 621 to move back and forth. The piston 62 inside the pneumatic cylinder 61 pushes air to flow only in one direction into the air storage tank 64, meaning that the pneumatic cylinder 61 injects air into the air storage tank 64 during its reciprocating stroke. An air supply pipe connects the air turbine 63 and the air storage tank 64. 65. A switch 651 can be installed on the air supply pipe 65, and the switch 651 can control the maximum flow rate into the air turbine 63 and close the air supply pipe 65. The float 50 rises and falls with the waves, causing the piston 62 to reciprocate linearly. When the piston 62 moves up or down, it can compress air through the one-way valve pipe 641, allowing the compressed air to be stored in the air tank 64. The air turbine 63 is driven by the controllable air flow, that is, the compressed air drives the air turbine 63 to rotate and drive the first generator 10 to generate electricity. This achieves the purpose of the float 50 generating electricity effectively when rising or falling. The first generator 10 can also be replaced by a linear generator, allowing the push rod 621 to directly reciprocate and drive the first generator 10 to generate electricity through reciprocating linear motion. This is the equivalent effect of multi-directional drive power generation of the present invention. Furthermore, the above mechanism can also be changed to inject liquid, with circulating liquid driving the liquid turbine, which can also achieve the equivalent power generation purpose.

[0085] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention; that is, all equivalent changes and modifications made in accordance with the claims of the present invention should still fall within the scope of the present invention.
