Description

Technical Field

[0001] This utility model belongs to the field of wave power generation technology, and specifically relates to a wave power generation device. Background Technology

[0002] Modern society has an ever-increasing demand for electricity. Traditional coal-fired power generation causes air pollution and damages the ecological environment, which is inconsistent with the concept of sustainable development. With the development of technology and the improvement of environmental awareness, green energy is receiving more and more attention. Currently, the development of green energy sources such as wind power, solar power, and wave power has become a focus of energy development. Among them, wave power generation utilizes ocean waves blown by sea breezes, which contain a large amount of energy. Using wave power generation devices, this portion of ocean waves can be converted into electricity for people's production and daily life.

[0003] Existing technologies disclose wave power generation devices, such as CN217462404U, which discloses a wave power generation system. This system includes a main unit base on which a generator is mounted. A main drive shaft extends through the top of the main unit base, and a one-way inertial ratchet pulley is mounted at one end of the main drive shaft. The main drive shaft is also connected to a rocker arm. The one-way inertial ratchet pulley is connected to the generator via a belt, and a buoyancy device is mounted at the end of the rocker arm. This patent discloses a massive power generation system that utilizes the energy provided by ocean waves to generate electricity, achieving the utilization of clean energy. Simultaneously, the buoyancy device follows the up-and-down movement of the waves, and the force of the rocker arm's up-and-down movement is transmitted to the one-way inertial rotation device, thereby driving the generator to generate electricity. This system has promising prospects for widespread application.

[0004] It is undeniable that the wave power generation system disclosed in this patent can indeed achieve the above-mentioned technical effects, but it still has some shortcomings: it only sets up a buoyancy device on one side of the main unit base, and can only use the buoyancy generated by the waves on the buoyancy device or the gravity of the buoyancy device when it falls to drive the unidirectional inertial ratchet pulley to rotate, thereby driving the generator to generate electricity. The power generation effect needs to be further improved.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a wave power generation device to solve the problems existing in wave power generation systems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A wave power generation device, comprising:

[0009] A frame on which a generator is fixed;

[0010] A transmission component, fixed to the frame and drivingly connected to the generator, includes a rotating shaft, a buoyancy transmission wheel, a first one-way bearing, a gravity transmission wheel, and a second one-way bearing. The rotating shaft has seated bearings at both ends, which are rotatably connected to it and fixed to the frame. The first one-way bearing is fixed at the center of the buoyancy transmission wheel and to the rotating shaft. The second one-way bearing is fixed at the center of the gravity transmission wheel and to the rotating shaft.

[0011] A buoyancy drive component is fixed to one side of the frame and is connected to the buoyancy drive wheel.

[0012] A gravity drive component is fixed to the other side of the frame and is connected to the gravity drive wheel for transmission.

[0013] Preferably, the buoyancy drive component includes a first fixed shaft fixed on one side of the frame, a buoyancy drive wheel disposed on and rotatably engaged with the first fixed shaft, a buoyancy transmission arm fixed on the buoyancy drive wheel, and a first float fixed on the outer end of the buoyancy transmission arm; wherein the buoyancy drive wheel is throttle connected to the buoyancy transmission wheel.

[0014] Preferably, both the buoyancy drive wheel and the buoyancy transmission wheel are spur gears, and the buoyancy drive wheel meshes with the buoyancy transmission wheel.

[0015] Preferably, the gravity drive component includes a second fixed shaft fixed on the other side of the frame, a gravity drive wheel disposed on the second fixed shaft and rotatably cooperating with it, a gravity transmission arm fixed on the gravity drive wheel, and a second float fixed on the outer end of the gravity transmission arm.

[0016] Preferably, both the gravity drive wheel and the gravity transmission wheel are spur gears, and the gravity drive wheel meshes with the gravity transmission wheel.

[0017] Preferably, the transmission component further includes a pulley, which is fixed on the rotating shaft and connected to the generator input shaft via belt drive.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention features buoyancy-driven and gravity-driven components on both sides of the frame. When the float in the buoyancy-driven component swings upward under buoyancy, it drives the transmission component to rotate, thereby powering the generator. Furthermore, when the float in the buoyancy-driven component swings downward, it does not interfere with the rotation of the rotating shaft in the transmission component. Similarly, when the float in the gravity-driven component swings downward under its own weight, it drives the transmission component to rotate, thereby powering the generator. Again, when the float in the gravity-driven component swings upward under buoyancy, it does not interfere with the rotation of the rotating shaft in the transmission component. This arrangement of buoyancy-driven and gravity-driven components on both sides of the frame allows both to drive the transmission component to rotate, thus powering the generator and improving power generation efficiency. Additionally, it helps maintain the frame's balance. Attached Figure Description

[0029] Example

[0030] See appendix Figure 1-3 A wave power generation device, comprising:

[0031] Frame 1, on which a generator 11 is fixed;

[0032] Transmission component 2 is fixed to the frame 1 and drives the generator 11. Transmission component 2 includes a rotating shaft 21, a buoyancy transmission wheel 22, a first one-way bearing 23, a gravity transmission wheel 24, and a second one-way bearing 25. Both ends of the rotating shaft 21 are provided with seated bearings 26 that are rotatably connected to it, and the seated bearings 26 are fixed to the frame 11. The first one-way bearing 23 is fixed at the center of the buoyancy transmission wheel 22 and fixed to the rotating shaft 21. The second one-way bearing 25 is fixed at the center of the gravity transmission wheel 24 and fixed to the rotating shaft 21. It should be noted that the inner ring of the first one-way bearing 23 is fixed to the rotating shaft 21, and the outer ring is fixed to the buoyancy transmission wheel 22; the inner ring of the second one-way bearing 25 is fixed to the rotating shaft 21, and the outer ring is fixed to the gravity transmission wheel 24.

[0033] The buoyancy drive component 3 is fixed to one side of the frame 1 and is connected to the buoyancy transmission wheel 22. Specifically, the buoyancy drive component 3 includes a first fixed shaft 31 fixed to one side of the frame 1, a buoyancy drive wheel 32 disposed on the first fixed shaft 31 and rotatably engaged with it, a buoyancy transmission arm 33 fixed on the buoyancy drive wheel 32, and a first float 34 fixed to the outer end of the buoyancy transmission arm 33. The buoyancy drive wheel 32 is connected to the buoyancy transmission wheel 22. In this embodiment, both the buoyancy drive wheel 32 and the buoyancy transmission wheel 22 are spur gears, and the buoyancy drive wheel 32 meshes with the buoyancy transmission wheel 22. It should be noted that a bearing is provided at the center of the buoyancy drive wheel 32, with the outer ring of the bearing fixed to the buoyancy drive wheel 32 and the inner ring fixed to the first fixed shaft 31, thus realizing the rotatable engagement between the buoyancy drive wheel 32 and the first fixed shaft 31.

[0034] The gravity drive component 4 is fixed to the other side of the frame 1 and is connected to the gravity transmission wheel 24. Specifically, the gravity drive component 4 includes a second fixed shaft 41 fixed to the other side of the frame 1, a gravity drive wheel 42 disposed on the second fixed shaft 41 and rotatably engaged with it, a gravity transmission arm 43 fixed to the gravity drive wheel 42, and a second float 44 fixed to the outer end of the gravity transmission arm 43. In this embodiment, both the gravity drive wheel 42 and the gravity transmission wheel 24 are spur gears, and the gravity drive wheel 42 meshes with the gravity transmission wheel 24. It should be noted that a bearing is provided at the center of the gravity drive wheel 42, with the outer ring of the bearing fixed to the gravity drive wheel 42 and the inner ring fixed to the second fixed shaft 41, thus realizing the rotational engagement of the gravity drive wheel 42 and the second fixed shaft 41.

[0035] In this embodiment, the transmission component 2 also includes a pulley 27, which is fixed on the rotating shaft 21 and connected to the input shaft of the generator 11 via a belt 28.

[0036] When in use, the frame 1 is set on the sea surface. Specifically, a buoyancy plate is set at the bottom of the frame 1 to float the frame 1 on the sea surface. At the same time, the bottom of the buoyancy plate is fixed with ropes to prevent the buoyancy plate from drifting with the waves.

[0037] See Figure 1 In the direction of the first float 34, as it swings up and down with the waves, when the first float 34 swings upward due to the buoyancy of the waves, the first float 34 drives the buoyancy drive wheel 32 to rotate clockwise through the buoyancy transmission arm 33. The buoyancy drive wheel 32, through its meshing relationship with the buoyancy transmission wheel 22, drives the buoyancy transmission wheel 22 to rotate counterclockwise. The buoyancy transmission wheel 22, through the first one-way bearing 23, drives the rotating shaft 21 to rotate counterclockwise. The rotating shaft 21 drives the pulley 27 to rotate. The pulley 27, through the belt 28, drives the rotor of the generator 11 to rotate, thus generating electricity. When the first float 34 swings downward due to its own weight, the first float 34 drives the buoyancy drive wheel 32 to rotate counterclockwise through the buoyancy transmission arm 33. The buoyancy drive wheel 32, through its meshing relationship with the buoyancy transmission wheel 22, drives the buoyancy transmission wheel 22 to rotate clockwise. The buoyancy transmission wheel 22 drives the outer ring of the first one-way bearing 23 to rotate freely. In this way, when the first float 34 swings downward, it cannot drive the rotating shaft 21 to rotate. In summary, when the first buoyancy 34 swings upward, it drives the rotating shaft 21 to rotate, which in turn drives the generator 11 to generate electricity. When the first float 34 swings downward, it does not interfere with the rotation of the rotating shaft 21.

[0038] As the second float 44 swings up and down with the waves, when it swings upward due to the buoyancy of the waves, it drives the gravity drive wheel 42 to rotate counterclockwise via the gravity transmission arm 43. The gravity drive wheel 42, through its meshing relationship with the gravity transmission wheel 24, drives the gravity transmission wheel 24 to rotate clockwise. The gravity transmission wheel 24 causes the outer ring of the second one-way bearing 25 to rotate freely, so that the second float 44 cannot drive the rotating shaft 21 to rotate when it swings upward. When the second float 44 swings downward due to its own weight, it drives the gravity drive wheel 42 to rotate clockwise via the gravity transmission arm 43. The gravity drive wheel 42, through its meshing relationship with the gravity transmission wheel 24, drives the gravity transmission wheel 24 to rotate counterclockwise. The gravity transmission wheel 24, through the second one-way bearing 25, drives the rotating shaft 21 to rotate counterclockwise. The rotating shaft 21 drives the pulley 27 to rotate, and the pulley 27, through the belt 28, drives the rotor of the generator 11 to rotate, thereby generating electricity. In summary, when the second float 44 swings downward, it drives the rotating shaft 21 to rotate, which in turn drives the generator 11 to generate electricity. When the second float 44 swings upward, it does not interfere with the rotation of the rotating shaft 21.
