Description

Technical Field

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

[0002] Ocean energy, along with tidal energy, ocean thermal energy, salinity gradient energy, and ocean current energy, is one of the richest, most widespread, and most difficult-to-utilize ocean energy resources. Wave energy constitutes a significant portion of ocean energy. The movement of ocean waves generates enormous amounts of energy. It is estimated that wave energy in the world's oceans reaches 70 billion kilowatts, accounting for 94% of all ocean energy.

[0003] Wave energy is a low-density, unstable, pollution-free, renewable, abundant, widely distributed, and difficult-to-utilize energy source. Because the utilization of wave energy is limited to areas near the coast, it is also susceptible to marine-related hazardous weather.

[0004] For example, CN201811290886.2 discloses a mechanically driven pendulum wave power generation device with adjustable pendulum density. To improve power generation efficiency, a wave-concentrating plate can be added, but the wave-concentrating plate is easily damaged when subjected to severe weather. Summary of the Invention

[0005] In view of this, it is necessary to provide a wave-focusing pendulum wave energy power generation platform to solve the technical problem that the wave-focusing plates of existing power generation platforms are easily damaged by hazardous weather.

[0006] This invention provides a wave-focusing pendulum wave energy power generation platform, which includes: a platform body, a wave-focusing unit, a folding unit, and a power generation unit. The platform body includes an upper base plate, and the wave-focusing unit includes two wave-focusing plates. The wave-focusing plates have a first state perpendicular to the upper base plate and a second state abutting against the upper base plate. When the wave-focusing plates are in the first state, a wave-focusing channel is formed between the two wave-focusing plates. The folding unit is disposed on the upper base plate and is drivenly connected to the two wave-focusing plates to drive the wave-focusing plates to switch between the first state and the second state. The power generation unit is disposed in the wave-focusing channel and can generate electricity using waves.

[0007] Furthermore, the folding unit includes two first telescopic mechanisms disposed on the upper base plate. The first telescopic mechanisms are connected one-to-one with the wave-gathering plate to drive the wave-gathering plate to switch between the first state and the second state.

[0008] Furthermore, the wave-gathering plate includes a central plate and two side plates connected to the two sides of the central plate respectively. The angle between the side plates and the central plate is an obtuse angle so that the openings at both ends of the wave-gathering channel are funnel-shaped. The first telescopic mechanism is connected to the central plate in a transmission connection.

[0009] Furthermore, the side plate is rotatably connected to the center plate, and the folding unit also includes a second telescopic mechanism, which is disposed on the center plate and is connected to the side plate for transmission, in order to adjust the angle between the side plate and the center plate.

[0010] Furthermore, the power generation unit includes a generator, a swing plate, and a rotating shaft. The generator is fixed on the upper base plate, the swing plate is arranged in the wave-gathering channel and perpendicular to the length direction of the wave-gathering channel, the swing plate is fixedly connected to the rotating shaft, and the two ends of the rotating shaft are respectively connected to two generators to drive the generators to generate electricity.

[0011] Furthermore, the power generation unit also includes a one-way clutch and a coupling, with both ends of the shaft connected to the generator in sequence via the one-way clutch and the coupling.

[0012] Furthermore, a water storage chamber is formed inside the plate, and the power generation unit also includes a water pump connected to the water storage chamber, which can adjust the amount of water stored in the water storage chamber.

[0013] Furthermore, the platform body also includes multiple pile legs and a lifting device. The lifting device is installed on the pile legs and is connected to the upper base plate to drive the upper base plate to move up and down along the pile legs.

[0014] Furthermore, the platform body also includes a lower base plate and a rotating device. The lifting device is connected to the lower base plate in a transmission manner, and the rotating device is mounted on the lower base plate and connected to the upper base plate in a transmission manner to drive the upper base plate to rotate.

[0015] Furthermore, the lifting device includes a buoy, a spring, and a brake clamp. The lower base plate is sleeved on the pile leg and slidably connected to the pile leg. The buoy is set above the lower base plate. The upper and lower ends of the spring are fixedly connected to the buoy and the lower base plate, respectively. The brake clamp is set on the lower base plate and movably connected to the pile leg. The brake clamp can lock the lower base plate at any position on the pile leg.

[0016] Compared with the prior art, the wave-focusing pendulum wave energy power generation platform provided by the present invention is equipped with a folding unit, which can change the wave-focusing plate from the first state with wave-focusing function to the second state of being close to the upper base plate, protecting the wave-focusing plate in the event of severe weather and making the wave-focusing plate less susceptible to damage.

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0025] Please see Figures 1 to 5 This invention provides a wave-focusing pendulum wave energy power generation platform. This wave-focusing pendulum wave energy power generation platform is generally used near the coast to generate electricity using ocean waves.

[0026] This wave-focusing pendulum wave energy generation platform includes a platform body 1, wave-focusing units 2, folding units 3, and a power generation unit 4. The platform body 1 includes an upper base plate 11. The wave-focusing unit 2 includes two wave-focusing plates 21, which have a first state perpendicular to the upper base plate 11 and a second state abutting against the upper base plate 11. When the wave-focusing plates 21 are in the first state, a wave-focusing channel is formed between the two wave-focusing plates 21. The folding unit 3 is disposed on the upper base plate 11 and is connected to the two wave-focusing plates 21 for transmission, thereby driving the wave-focusing plates 21 to switch between the first and second states. The power generation unit 4 is disposed within the wave-focusing channel and can generate electricity using waves.

[0027] During normal power generation, the two wave-gathering plates 21 are in the first state, used to gather waves and improve the power generation efficiency of the power generation unit 4. When encountering severe weather, the folding unit 3 moves the wave-gathering plates 21 to the second state, where they are placed against the upper base plate 11 to reduce the area exposed to wind and waves and prevent damage.

[0028] In this embodiment, the platform body 1 also includes multiple legs 12 and a lifting device 13. The legs 12 are vertically arranged and their lower ends are fixed to the seabed. The lifting device 13 is disposed on the legs 12 and is connected to the upper base plate 11 for transmission, so as to drive the upper base plate 11 to move up and down along the legs 12, thereby adapting the power generation unit 4 to the height of the sea level to obtain better power generation efficiency.

[0029] In some embodiments, the platform body 1 further includes a lower base plate 14 and a rotating device 15, the rotating device 15 being disposed on the lower base plate 14 and tractively connected to the upper base plate 11. The rotating device 15 can drive the upper base plate 11 to rotate, so that the power generation unit 4 faces the direction of the waves, thereby achieving better power generation efficiency. The rotating device 15 can be a suitable type of motor. In this embodiment, the lifting device 13 is tractively connected to the lower base plate 14, and drives the upper base plate 11 to move up and down via the lower base plate 14 and the rotating device 15.

[0030] In this embodiment, the lifting device 13 includes a buoy 131, a spring 132, and a brake clamp 133. A lower base plate 14 is sleeved on and slidably connected to the pile leg 12. The pile leg 12 restricts the movement direction of the lower base plate 14, allowing it to move only along the lower base plate 14. The buoy 131 is positioned above the lower base plate 14. The upper and lower ends of the spring 132 are fixedly connected to the buoy 131 and the lower base plate 14, respectively. The brake clamp 133 is positioned on the lower base plate 14 and movably connected to the pile leg 12, allowing the lower base plate 14 to be locked at any position on the pile leg 12. In a preferred embodiment, the lifting device 13 further includes a guide wheel 134 disposed on the lower base plate 14. The guide wheel 134 abuts against the pile leg 12 to make the lower base plate 14 slide more smoothly along the pile leg 12.

[0031] When the brake clamp 133 releases the leg 12, the buoy 131 floats on the sea surface. As long as the power generation part of the power generation unit 4 is at the same height as the buoy 131, the power generation unit 4 can achieve good power generation efficiency. Then, the brake clamp 133 clamps the leg 12 to fix its position. Afterwards, during the power generation process, the up-and-down fluctuations of the buoy 131 caused by the waves are absorbed by the spring 132 and will not affect the lower base plate 14, causing the lower base plate 14 to change position. This ensures that the power generation unit 4 is in a suitable power generation position. When the sea level changes significantly, the brake clamp 133 releases the leg 12, and under the action of gravity and buoyancy, the buoy 131 will float on the sea surface again. The height correction can then be completed by controlling the brake clamp 133 to clamp the leg 12 again.

[0032] In other embodiments, the lifting device 13 may also be designed to be powered, such as an electric push rod, to actively push the upper base plate 11 or the lower base plate 14 to adapt to different sea level heights.

[0033] In this embodiment, the wave-gathering plate 21 includes a central plate 211 and two side plates 212 respectively connected to both sides of the central plate 211. The included angle between the side plates 212 and the central plate 211 is an obtuse angle so that the openings at both ends of the wave-gathering channel are funnel-shaped, so as to better gather waves and improve power generation efficiency. In a preferred embodiment, the side plates 212 and the central plate 211 are rotatably connected, and the included angle between them can be adjusted according to the size of the waves.

[0034] In this embodiment, the folding unit 3 includes two first telescopic mechanisms 31 disposed on the upper base plate 11. The first telescopic mechanisms 31 are connected one-to-one with the wave-gathering plates 21 to drive the wave-gathering plates 21 to switch between a first state and a second state. Specifically, the first telescopic mechanisms 31 are connected to the center plate 211 in a transmission manner. The first telescopic mechanisms 31 are preferably electrically driven devices, such as electric push rods, to drive the wave-gathering plates 21 to move.

[0035] In some embodiments, the folding unit further includes a second telescopic mechanism 32, which is disposed on the center plate 211 and connected to the side plate 212 for adjusting the angle between the side plate 212 and the center plate 211. In the event of severe weather, the side plate 212 can be driven to press against the center plate 211, and the first telescopic mechanism 31 can drive the center plate to press against the upper bottom plate 11, further reducing the area exposed to wind and waves.

[0036] In this embodiment, the power generation unit 4 includes a generator 41, a swing plate 42, and a rotating shaft 43. The generator 41 is fixed on the upper base plate 11. The swing plate 42 is arranged in the wave-gathering channel and perpendicular to the length direction of the wave-gathering channel. The swing plate 42 is fixedly connected to the rotating shaft 43. The two ends of the rotating shaft 43 are respectively connected to the two generators 41 to drive the generators 41 to generate electricity.

[0037] The rotating device 15 can make the wave-gathering channel face the direction of the wave. The wave enters from one end of the wave-gathering channel and leaves from the other end, pushing the swing plate 42 to swing back and forth. The swing plate 42 drives the rotating shaft 43 to rotate back and forth, driving the generator 41 to generate electricity.

[0038] In a preferred embodiment, the power generation unit 4 further includes a one-way clutch 44 and a coupling 45, and both ends of the rotating shaft 43 are connected to the generator 41 in sequence through the one-way clutch 44 and the coupling 45.

[0039] When the swing plate 42 drives the rotating shaft 43 to rotate in one direction, one of the one-way clutches 44 locks, transmitting the force of the rotating shaft 43 to the generator 41 connected to it, causing the generator 41 to do work. The other one-way clutch 44 is in a free-rotating state and does not transmit work. Similarly, when the swing plate 42 rotates in the other direction, the first one-way clutch 44 will be in a free-rotating state and will not transmit work. The generator 41 on its side will continue to generate electricity under the inertia of the flywheel. At this time, the second one-way clutch 44 locks, transmitting the force of the rotating shaft 43 to the generator 41 to generate electricity.

[0040] This structure allows the generators 41 on both sides of the pendulum 42 to rotate in one direction, thereby capturing wave energy from any direction. The flywheel keeps the speed of the generators 41 within a certain range, resulting in a smoother change in the output voltage of the generators 41 and achieving primary voltage regulation.

[0041] It is easy to understand that the electricity generated by the generator 41 can be transmitted to the power grid through cables or stored in the power generation platform through batteries. Furthermore, the batteries can also be used to power electrical equipment such as lifting devices 13, rotating devices 15, brake clamps 133, first telescopic mechanism 31, second telescopic mechanism 32, etc. The installation of cables or batteries and the circuit layout are conventional technologies in this field and will not be elaborated here.

[0042] In this embodiment, a water storage cavity is formed inside the pendulum plate 42, and the power generation unit 4 also includes a water pump (not shown) connected to the water storage cavity. The water pump can adjust the amount of water stored in the water storage cavity to change the overall mass of the pendulum plate 42 when it swings, thereby changing the natural frequency of the pendulum plate 42 to adapt to the wave parameters, so as to obtain a larger swing amplitude and thus increase the wave energy capture efficiency.

[0043] As is easily understood, this power generation platform is used at sea, so all components have been treated with waterproofing and corrosion protection as required.

[0044] Compared with the prior art, the wave-focusing pendulum wave energy power generation platform provided by the present invention is equipped with a folding unit, which can change the wave-focusing plate from the first state with wave-focusing function to the second state of being close to the upper base plate, protecting the wave-focusing plate in the event of severe weather and making the wave-focusing plate less susceptible to damage.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
