Description

Technical Field

[0001] This invention relates to the field of energy technology, and in particular to a wave power generation device. Background Technology

[0002] Wave energy is the kinetic and potential energy of ocean surface waves. Wave energy power generation devices are devices that capture wave energy and convert it into electrical energy. Due to the huge reserves of ocean wave energy resources and broad development prospects, wave energy power generation devices have become a hot topic in ocean energy utilization research at home and abroad in recent years.

[0003] Oscillating buoy-type wave energy generators obtain energy by using a buoy floating on the sea surface and moving under the influence of waves. The wave energy absorbed by the buoy is then converted into electricity through mechanical or hydraulic devices to drive a generator. However, the buoys in existing oscillating buoy-type wave energy generators are affected by the size, frequency, and direction of the waves, resulting in decreased power generation efficiency when the waves are small or unstable. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a wave power generation device that utilizes the surging of waves and can collect kinetic energy from them from all directions, converting the kinetic energy into electrical energy, thereby improving power generation efficiency.

[0010] An elastic element, one end of which is connected to the housing and the other end of which is connected to the drive shaft of the transmission assembly;

[0011] A drive assembly is rotatably mounted on the base. After installation, the drive assembly contacts the transmission assembly, and the drive assembly drives the transmission assembly to move under the action of waves.

[0012] When the drive component drives one of the transmission components to rotate, the other drive component loses its load balance and, under the action of the elastic element, drives the other transmission component to rotate in the same direction as the first transmission component.

[0013] Optionally, the top of the base is provided with a spherical mounting groove.

[0014] Optionally, the transmission assembly includes:

[0015] Two gear shafts are installed inside the housing and are located on opposite sides of the base after installation;

[0017] The driving gear is mounted on both of the gear shafts;

[0018] The driven gear is installed inside the housing and meshes with the two driving gears. The motor shaft of the generator is connected to the driven gear.

[0019] Optionally, the gear shaft is mounted in the housing via a one-way bearing.

[0020] Optionally, the elastic element is a tension spring, a compression spring, or a disc spring.

[0021] Optionally, the driving component includes:

[0024] A wave-collecting plate is installed on top of the rotary table and is located outside the housing after installation;

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This drive component can collect the kinetic energy of wave surges from all directions, and then use the wave surges to drive the drive component to move, converting kinetic energy into electrical energy and improving power generation efficiency.

[0032] 2. Because wave surges are continuous and their direction is uncertain, the drive component will continuously rotate around the base under the load generated by the wave surge, and then output torque through the transmission component. The generator will then continuously generate electricity after receiving the output torque.

[0033] 3. Use elastic elements to limit the transmission components, so that the drive components can be easily reset after the force is released, and prepare for the next operation. Attached Figure Description

[0050] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0051] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment of the invention provides a wave power generation device, including: a housing 1, a base 2, a transmission assembly 3, an elastic element 4, and a drive assembly 5. The housing 1 is connected to a floating body disposed on the water surface. The base 2 is disposed inside the housing 1. The transmission assembly 3 is installed inside the housing 1, and after installation, it is located on opposite sides of the base 2. The driven shaft of the transmission assembly 3 is connected to a generator. One end of the elastic element 4 is connected to the housing 1, and the other end is connected to the drive shaft of the transmission assembly 3. The drive assembly 5 is rotatably mounted on the base 2. When the drive assembly 5 is installed and comes into contact with the transmission assembly 3, the drive assembly 5 drives the transmission assembly 3 to move under the action of waves. When the drive assembly 5 drives one of the transmission assemblies 3 to rotate, the other transmission assembly 3 loses its balancing load and, under the action of the elastic element 4, drives the other transmission assembly 3 to rotate in the same direction as the first transmission assembly 3.

[0052] During use, the tank 1 is connected to the float to prevent the tank 1 from sinking to the bottom of the water. When waves rise on the water surface, the waves crash onto the drive component 5, which transfers the kinetic energy of the waves to the transmission component 3 in contact with it. The transmission component 3 then transfers the kinetic energy to the generator, which converts the kinetic energy into electrical energy.

[0053] To facilitate the movement of the drive assembly 5 and the transmission assembly 3 under the influence of waves, the drive assembly 5 and the base 2 are rotatably connected. To ensure that the two sets of transmission assemblies 3 are in a balanced state when unaffected by waves, the transmission assembly 3 and the housing 1 are connected by an elastic element 4.

[0054] When the waves crash against the drive assembly 5, the drive assembly 5 rotates around the base 2 with the surge of the waves. During the rotation, it transfers kinetic energy to the transmission assembly 3 in contact with it. The transmission assembly 3 then transfers the kinetic energy to the generator, which converts the kinetic energy into electrical energy.

[0055] It should be noted that since the tank 1 will be submerged below the water surface, there is no need to implement additional temperature control measures for the generator inside the tank 1 (temperature control is mainly to deal with the heat generated by the generator during operation).

[0056] To improve the service life of enclosure 1, the exterior of enclosure 1 was treated with anti-corrosion measures.

[0057] More specifically, in order to facilitate the rotation of the drive assembly 5 around the base 2 at multiple angles, a spherical mounting groove 21 is provided on the top of the base 2, and the drive assembly 5 is rotatably mounted in the mounting groove 21.

[0058] Because wave surges are continuous and their direction is uncertain, the drive component 5 will continuously rotate around the base 2 under the load generated by the wave surges, and then output torque through the transmission component 3. After the generator receives the output torque, it will continuously generate electricity.

[0059] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the transmission assembly 3 includes: two gear shafts 31, connecting members 32, a driving gear 33, and a driven gear 34. The two gear shafts 31 are installed inside the housing 1, and after installation, they are located on opposite sides of the base 2. Connecting members 32 are installed on both gear shafts 31, and the connecting members 32 are in contact with the drive assembly 5. An elastic member 4 is connected to the connecting member 32. A driving gear 33 is installed on each of the two gear shafts 31. The driven gear 34 is installed inside the housing 1 and meshes with the two driving gears 33. The generator's motor shaft is connected to the driven gear 34.

[0060] In actual use, two gear shafts 31 are installed inside the housing 1, and the connecting piece 32 is welded to the gear shafts 31. The driving gear 33 is installed at one end of the gear shaft 31. The driven gear 34 is installed on the generator shaft and meshes with the two driving gears 33. After the gear shafts 31 are installed, the elastic member 4 is installed between the housing 1 and the connecting piece 32, ensuring that the connecting piece 32 is always in contact with the drive assembly 5. When waves surge onto the drive assembly 5, the drive assembly 5 moves and effectively drives the gear shafts 31 to rotate. During rotation, the gear shafts 31 drive the driving gears 33 and driven gears 34 to mesh. During meshing, the driving gears 33 and driven gears 34 transfer kinetic energy to the generator, which converts this kinetic energy into electrical energy.

[0061] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, in order to avoid reverse rotation during use, which could damage the generator, the gear shaft 31 is installed inside the housing 1 via a one-way bearing 35.

[0062] In one embodiment, the elastic element 4 is a tension spring, compression spring, or disc spring for easy positioning.

[0063] In one embodiment, the drive assembly 5 includes a connecting rod 51, a rotary table 52, a wave-receiving plate 53, and a flexible seal 54. One end of the connecting rod 51 is rotatably connected to the base 2. The rotary table 52 is mounted on the other end of the connecting rod 51, and its bottom contacts the transmission assembly 3. The wave-receiving plate 53 is mounted on top of the rotary table 52 and is located outside the housing 1 after installation. The wave-receiving plate 53 is connected to the top of the housing 1 by the flexible seal 54.

[0064] During operation, to facilitate the impact of waves on the wave-receiving plate 53 during surging, the wave-receiving plate 53 is installed on the outside of the housing 1, ensuring that waves from any direction can propel it. To prevent water from entering the housing 1 and affecting the service life of the transmission assembly 3 and the generator, a flexible seal 54 is installed between the wave-receiving plate 53 and the housing 1. The flexible seal 54 is used to prevent interference with the movement of the wave-receiving plate 53 under stress.

[0065] During the transfer of kinetic energy, the surging of the waves brings kinetic energy to the wave-receiving plate 53. After receiving the kinetic energy, the wave-receiving plate 53 transfers it to the rotating platform 52 connected to it. The rotating platform 52 rotates around the base 2, transferring the kinetic energy to the connecting member 32 in contact with it during the rotation. Then, the connecting member 32 drives the elastic member 4 and the gear shaft 31 to rotate. The meshing of the driving gear 33 and the driven gear 34 transfers the kinetic energy to the generator, and the generator converts the kinetic energy into electrical energy.

[0066] In one embodiment, a sail is provided on the top of the wave-receiving plate 53. When the waves cannot hit the wave-receiving plate or the force of hitting the wave-receiving plate is insufficient, the wind on the water surface can drive the sail to move, which in turn drives the rotary table 52 to move and transmits kinetic energy to the connector 32.

[0067] In one embodiment, such as Figure 1 As shown, in order to reduce the weight of the rotary table 52 and save materials, the rotary table 52 has a triangular structure.

[0068] In one embodiment, such as Figure 1 As shown, in order to prevent the edges of the rotary table 52 from causing injury to the operator during installation or maintenance, rounded corners are provided at all corners of the rotary table 52.

[0069] In one embodiment, such as Figure 3 As shown, in order to facilitate the free rotation of the rotary table 52 within the base 2, when the base 2 is provided with an mounting groove 21, a rotating block 55 is provided at one end of the connecting rod 51.

[0070] When the mounting groove 21 has a spherical structure, the rotating block 55 mates with it. It is understood that this mating structure is a ball joint, which allows for rotation under different angles of force.

[0071] In one embodiment, such as Figure 4 As shown, in order to facilitate the wave-receiving plate 53 to bear force in different directions, the wave-receiving plate 53 is set as a columnar structure, and an inclined wave-receiving surface 56 is provided on its outer side wall.

[0072] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
