Description

Technical Field

[0001] This utility model relates to the field of marine power generation technology, specifically to a mechanical composite transmission wave energy power generation device. Background Technology

[0002] Wave energy power generation devices are closely related to the growing global demand for renewable energy, the transformation of the energy structure, and the urgency of environmental protection. As a potential renewable energy source, wave energy possesses enormous development potential and environmental friendliness, thus attracting the research interest of scientists and engineers from many countries. Currently, research and development of wave energy power generation technology has made some progress. For example, the "High-Efficiency, Wide-Bandwidth, High-Reliability Aerodynamic Wave Energy Conversion Device," jointly developed by the China Academy of Ocean Engineering (Qingdao) and Tsinghua University, won a Special Commendation Gold Medal at the 49th Geneva International Exhibition of Inventions, demonstrating China's global leading position in wave energy conversion technology. Furthermore, the commissioning of the world's first megawatt-class floating wave energy power generation device marks a new stage in the development of wave energy power generation technology, moving from theoretical research to engineering practice.

[0003] Research on wave energy generation devices is of great significance for improving wave energy conversion efficiency, reducing costs, and enhancing the reliability and survivability of the devices. The successful development and application of this technology is expected to provide a stable green energy supply for remote islands, deep-sea platforms, and marine economic activities, while also helping to reduce dependence on fossil fuels, mitigate environmental pollution, and promote sustainable development.

[0004] Existing wave power generation devices suffer from low wave energy utilization rates due to the inconsistent buoyancy direction during wave energy transmission. To address this, we propose a mechanically composite transmission wave energy generation device. Utility Model Content

[0005] This invention provides a mechanical composite transmission wave energy generation device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a mechanical composite transmission type wave energy generation device, comprising:

[0008] Storage tube;

[0009] The base is threaded into the bottom of the storage tube, allowing for the disassembly and assembly of the transmission device.

[0010] The handle is fixedly attached to the lower surface of the base, allowing for the installation and removal of the base.

[0011] The transmission device, located inside the storage cylinder, is used to transmit the kinetic energy of the waves;

[0012] An auxiliary device, located inside the storage tube, assists the transmission device.

[0013] Furthermore, the transmission device includes a transmission spring, which is fixedly installed on the upper surface of the base. A sliding seat is provided on the upper surface of the transmission spring, and a hook is fixedly installed on the upper surface of the sliding seat. One end of the traction rope is fixedly connected to the hook. A support arm is fixedly installed on the outer surface of the storage tube. A generator wheel is rotatably installed on one end of the support arm, and a rotating arm is rotatably installed on one end of the support arm. A transmission wheel is rotatably installed on one end of the rotating arm, and a floating ball is fixedly connected to the other end of the traction rope.

[0014] The above technical solution utilizes a two-wheeled power generation system, where each wheel is a cylindrical device with an internal magnet and wires that generate electricity by rotating and cutting magnetic field lines. The belt is made of aramid fiber-reinforced rubber, using aramid, polyester, or high-molecular-weight polyethylene to ensure tensile strength, wear resistance, and corrosion resistance. The pulley bearings are made of alloy steel, stainless steel, or galvanized steel to prevent corrosion in marine or humid environments. The springs are made of corrosion-resistant galvanized metal.

[0015] Furthermore, the sliding seat is slidably mounted to the storage cylinder, and the transmission spring is in contact with the surface of the sliding seat.

[0016] With the above technical solution, the sliding seat is slidably installed with the storage tube, which makes it easy for the floating ball to move up and down with the waves. The traction rope can be used to pull the sliding seat to slide inside the storage tube.

[0017] Furthermore, the upper surface of the storage tube is provided with a through hole, and the other end of the traction rope passes through the through hole and is wound around the generator wheel and the transmission wheel.

[0018] The above technical solution allows the other end of the traction rope to pass through the through hole and be wound and connected with the generator wheel and the transmission wheel.

[0019] Furthermore, the transmission spring is internally provided with a telescopic column, the lower end of which is fixedly installed with the base.

[0020] The above technical solution uses a telescopic column to support the extension and retraction of the transmission spring, making its movement more stable.

[0021] Furthermore, the auxiliary device includes a sliding bead, which is disposed inside the through hole. Both ends of the sliding bead are fixedly connected to rotating columns. The upper end of the telescopic column is fixedly connected to a threaded column. The lower surface of the sliding seat is provided with a threaded hole. One end of the rotating arm is fixedly connected to an elastic rope.

[0022] Through the above technical solution, the sliding bead can protect the traction rope, preventing it from being cut by the outer shell of the storage cylinder during back-and-forth movement. At the same time, the threaded post can facilitate the disassembly of the sliding seat and telescopic post, thus facilitating the disassembly and replacement of the transmission spring. The elastic rope can limit the maximum length of the traction rope, effectively preventing it from breaking and thus improving the service life of the device.

[0023] Furthermore, the rotating column is rotatably mounted to the storage cylinder, and the elastic rope is fixedly connected to the floating ball.

[0024] By employing the above technical solution, and through the fixed connection between the elastic rope and the floating ball, the breakage of the traction rope is effectively prevented, thereby extending the service life of the device.

[0025] Furthermore, the threaded post is disposed in the threaded hole, and the threaded post is threadedly installed with the sliding seat.

[0026] The above technical solution allows for the disassembly and installation of the transmission spring by connecting the threaded post to the sliding seat.

[0027] The above-described solution of this utility model has at least the following beneficial effects:

[0028] 1. This utility model simplifies the problem of inconsistent buoyancy direction during wave energy transfer by setting the tension of the traction rope, and adapts to the problem of power generation capacity changes under different wave conditions by changing the angle between the support arm and the rotating arm. The structure has stronger combinability and can be connected in parallel to enhance power generation capacity and quality.

[0029] 2. This utility model uses a sliding bead to protect the traction rope, preventing it from being cut by the outer shell of the storage tube during its back-and-forth movement. The threaded post facilitates the disassembly of the sliding seat and telescopic post, allowing for easy replacement of the transmission spring. The elastic rope limits the maximum length of the traction rope, effectively preventing it from breaking and thus extending the device's lifespan. Attached Figure Description

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 4 As shown, an embodiment of this utility model provides a mechanical composite transmission wave energy generation device, including: a storage cylinder 1; a base 2, threadedly installed at the bottom end inside the storage cylinder 1 to enable disassembly and assembly of the transmission device 4; a handle 3, fixedly connected to the lower surface of the base 2 to enable installation and disassembly of the base 2; the transmission device 4, disposed inside the storage cylinder 1, for transmitting the kinetic energy of the waves; and an auxiliary device 7, disposed inside the storage cylinder 1, to assist the transmission device 4.

[0038] like Figures 1 to 4As shown, the transmission device 4 includes a transmission spring 401, which is fixedly installed on the upper surface of the base 2. A sliding seat 402 is provided on the upper surface of the transmission spring 401, and a hook 403 is fixedly installed on the upper surface of the sliding seat 402. One end of the traction rope 404 is fixedly connected to the hook 403. A support arm 405 is fixedly installed on the outer surface of the storage cylinder 1. A generator wheel 406 is rotatably installed on one end of the support arm 405, and a rotating arm 407 is rotatably installed on the other end of the support arm 405. A transmission wheel 408 is rotatably installed on one end of the rotating arm 407. A floating ball 409 is fixedly connected to the other end of the traction rope 404. The sliding seat 402 is slidably installed with the storage cylinder 1, and the transmission spring 401 is in contact with the surface of the sliding seat 402. A through hole 6 is opened on the upper surface of the storage cylinder 1, and the other end of the traction rope 404 passes through the through hole 6 and is wound around the generator wheel 406 and the transmission wheel 408. The transmission spring 401 has a telescopic column 5 inside, and the lower end of the telescopic column 5 is fixedly installed to the base 2. By changing the position of the wave height, the generator wheel 406 is driven to rotate to generate electricity. Then, the transmission spring 401 guides it back to the original position to continue the next power generation cycle. When encountering different wave heights and wavelengths, the power generation efficiency can be enhanced by changing the arm span.

[0039] In this embodiment of the invention, when the waves rise, they will cause the floating ball 409 to rise, which will cause the traction rope 404 to pull the hook 403 and the sliding seat 402 to move upward. When the waves fall, under the elastic action of the transmission spring 401, the transmission spring 401 will rebound and pull the traction rope 404 to move. Thus, during the rise and fall of the waves, the traction rope 404 will drive the generator wheel 406 to rotate and generate electricity.

[0040] like Figures 1 to 4 As shown, the auxiliary device 7 includes a sliding bead 701, which is disposed inside the through hole 6. Rotating columns 702 are fixedly connected to both ends of the sliding bead 701. A threaded column 703 is fixedly connected to the upper end of the telescopic column 5. A threaded hole 704 is provided on the lower surface of the sliding seat 402. An elastic rope 705 is fixedly connected to one end of the rotating arm 407. The rotating column 702 is rotatably mounted to the storage cylinder 1, and the elastic rope 705 is fixedly connected to the floating ball 409. The threaded column 703 is disposed in the threaded hole 704 and threadedly mounted to the sliding seat 402. A water-proof outer shell is provided on the outer surface of the generator rotor 406 to protect it.

[0041] In this embodiment of the invention, the sliding bead 701 protects the traction rope 404 from being cut by the outer shell of the storage cylinder 1 during its back-and-forth movement. Simultaneously, the threaded post 703 facilitates the disassembly of the sliding seat 402 and the telescopic post 5, allowing for easy removal and replacement of the transmission spring 401. The elastic rope 705 limits the maximum length of the traction rope 404, effectively preventing it from breaking and thus improving the lifespan of the device.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
