Description

Water solar power generation device with semi-submersible floating body TECHNICAL FIELD

[0002] In order to reduce environmental pollution caused by coal-fired power generation, solar energy is a widely used alternative energy source. The solar power generation mainly converts sunlight received by solar panels into electrical energy. Currently, solar power generation devices are often installed on rooftops or land. However, due to limited land area, the solar power generation device can also be installed on a floating platform under a lake, pond or other water body for power generation.

[0003] When the solar power generation device is installed on the ground, the ground is more stable than water, so multiple solar panels can be installed in a large area, and the angles of the solar panels can be changed simultaneously to improve the power generation efficiency. However, when the solar power generation device is floating on the water body by the floating platform, the waves are blocked by the floating body of the platform, which is not environmentally friendly, causing the platform to shift significantly and making it difficult for multiple solar panels to change angles simultaneously. In addition, different angles of the solar panels have different wind resistance, which affects the stability of the platform and even causes the platform to overturn. Therefore, the solar power generation device on the water body has the defects of poor stability, difficulty in changing angles, and reduced power generation efficiency. SUMMARY

The solar panels 1 have a first light receiving surface 11 and a second light receiving surface 12 on opposite sides for receiving light to generate electricity.

In this embodiment, two solar power generation modules 6 are arranged in parallel, and an interval 60 is provided between the two solar power generation modules 6. A first pivot connection portion 61 is provided on each of the two solar power generation modules 6 near the interval 60. A second pivot connection portion 62 is provided on the side of each of the two solar power generation modules 6.

[0024] The sun tracking device 2 has a telescopic rod 21, a controller 22, a first connecting rod 23, and a second connecting rod 24. The telescopic rod 21 can be a pneumatic rod, an oil pressure rod, or an electric rod, and is provided at the interval 60. The telescopic rod 21 has a cylinder 210, which is arranged horizontally above the support frame 3. In this embodiment, the cylinder 210 is arranged on the plate 5 above the support frame 3. The cylinder 210 has a first actuating rod 211 and a second actuating rod 212, which are arranged on opposite sides of the cylinder 210 and can be connected in axial direction. The controller 22 is connected to the telescopic rod 21 and can control the operation of the first actuating rod 211 and the second actuating rod 212. The first connecting rod 23 is pivotally connected to the first actuating rod 211 at one end and to the first pivot connection portion 61 of one of the solar power generation modules 6 at the other end. The second connecting rod 24 is pivotally connected to the second actuating rod 212 at one end and to the first pivot connection portion 61 of the other solar power generation module 6 at the other end.

[0025] The support frame 3 is made of a high-reflectivity structural material and is arranged below the solar panels 1. The support frame 3 has a base frame portion 31 formed by a plurality of frame bodies arranged in a cross shape. The vertical frame 32 is connected to the second pivot connection portion 62 of the solar power generation module 6 and is pivotally connected to the first pivot connection portion 61 of the other solar power generation module 6.

[0026] The floating device 4 comprises a horizontal straight hollow cylindrical main float 41 with buoyancy, a plurality of vertical auxiliary floats 42 with buoyancy, each main float 41 has a spacing and is arranged horizontally below the bottom frame 31 of the support frame 3, and is combined with a plurality of connecting members 411 on the surface, each connecting member 411 has a spacing, the connecting member 411 can be sleeved with the sleeve part 412 on the surface of the main float 41, and a vertical pipe part 413 is arranged above the sleeve part 412. The auxiliary float 42 is a straight hollow cylindrical body, the bottom has a sleeve hole 421 combined with the vertical pipe part 413 of the connecting member 411, and the top is fixed to the bottom frame 31 of the support frame 3 by bolts, ropes or other connecting elements (not shown in the figure), and the combined auxiliary floats 42 have a flow guide spacing 43, and the connecting member 411 has the effects of easy assembly and stability.

[0027] The plate 5 is a straight strip-shaped plate body fixed above the bottom frame 31 of the support frame 3, and a wave part 51 is arranged on the top, and the wave part 51 has different angle reflecting surfaces 52, so that the wave part 51 can improve the structural strength of the plate 5. Each reflecting surface 52 can provide sunlight to irradiate the plate 5 to produce a diffuse effect, and three plates 5 are arranged between two solar power generation modules 6 and on the outer side of the solar power generation module 6, which can provide average stable combination with the support frame 3 to improve the overall structural strength. The three floating devices 4 are arranged below the corresponding plate 5, which can transmit the force to the plate 5 with better strength when the floating device 4 is stressed, and can improve the better support stability.

[0028] The solar power generation module 6, the sun tracking device 2, the support frame 3, the floating device 4 and the plate 5 can form a floating power generation module 7 which can float on the water body 8, and a plurality of floating power generation modules 7 can be arranged on the lake surface, pond or other water body 8 for large-area power generation.

[0029] Please refer to FIG. 4 and FIG. 5, when the floating power generation module 7 is arranged on the water body 8, the main float 41 has a total volume and the auxiliary float 42 has a partial volume, which can completely immerse in the water body 8 to form a semi-submersible floating shape, and the main floating force can be generated by the plurality of main floats 41, and the water flow below the water surface 81 can be guided by the spacing between the main floats 41 to reduce the fluctuation of the floating power generation module 7.

[0030] The auxiliary floating body 42 can provide auxiliary buoyancy to prevent the floating power generation module 7 from sinking into the water surface 81 when the floating power generation module 7 fluctuates up and down, and the waves on the water surface 81 can be guided out by the flow guide intervals 43 between the auxiliary floating bodies 42, which can have better environmental affinity and can reduce the influence of the waves on the water surface 81 to improve the floating stability of the floating power generation module 7. The three plates 5 and the corresponding three floating devices 4 can improve the overall strength and stability, and the sun tracking device 2 can drive the solar power generation module 6 to change the angle to track the sun in a more stable state.

[0031] The plate 5 of the present application can form a maintenance walkway to provide walking, and as shown in FIG. 5, the present application can generate electricity by sunlight irradiating the first light receiving surface 11 of the solar panel 1, and the sunlight irradiating the reflecting surface 52 of the plate 5 can produce diffusion, and the light can be projected to the second light receiving surface 12 of the solar panel 1 to generate electricity, and the support frame 3 can also reflect light to the solar panel 1, so that the solar power generation module 6 can receive sunlight from multiple directions to improve power generation efficiency.

[0032] Please refer to FIG. 6, the controller 22 of the sun tracking device 2 can control the extension rod 21 to move according to the sun's position, and the first actuator rod 211 and the second actuator rod 212 can move synchronously. When the first actuator rod 211 extends outward from the cylinder 210, it can drive the first connecting rod 23 to move and lift the solar power generation module 6 connected thereto, and the second actuator rod 212 can move toward the cylinder 210 and drive the second connecting rod 24 to pull the solar power generation module 6 connected thereto. Therefore, the two solar power generation modules 6 can be moved to approximately the same angle synchronously, which can have the same windward surface and wind resistance to improve the floating stability, and can avoid the difficulty of synchronous control when two controllers control two solar power generation modules 6 respectively (not shown in the figure), or the angle difference between the two solar power generation modules 6 is too large due to the damage of one of the controllers, which can cause the solar power generation modules 6 to overturn due to the windward turbulence. The synchronous control design of the present application can ensure that the two floating power generation modules 7 on the water body 8 move synchronously and can stabilize the sun tracking power generation effect.

[0033] In addition, the support frame 31 of the present application has a gap between each main floating body 41 of the floating device 4, so that when the two solar power generation modules 6 are lifted to a larger angle by the controller 22 of the sun tracking device 2, a large amount of sunlight can be projected onto the water body 8 through the above-mentioned gap, and the water body 8 can be exposed to sunlight for sterilization to maintain a better natural environment of the water body 8.

[0034] Therefore, according to the above description, the present application can have better floating stability and can greatly improve the power generation efficiency, and the floating power generation module of the present application can be provided with one, three or more than three solar power generation modules, and the foregoing embodiments are examples of the present application, not limitations of the present application, and any equivalent changes made in accordance with the spirit of the present application shall also fall within the scope of the present application.
