Description

Technical Field

[0001] This invention relates to the field of floating photovoltaic power generation devices, and more particularly to a deformation-resistant floating photovoltaic power generation device. Background Technology

[0002] Floating photovoltaic (PV) power generation devices, simply put, move PV power stations from land to water. It's a technology that uses buoyancy and anchoring systems to support and stabilize PV modules on the water surface for power generation, and is considered an important direction for resolving land use conflicts and expanding power generation space. Floating PV power generation devices directly utilize lakes, reservoirs, coal mining subsidence areas, coastal mudflats, and even near-shore waters, without occupying valuable arable or construction land. Furthermore, the water body has a natural cooling effect on the PV modules, lowering their operating temperature and improving power generation efficiency. Simultaneously, the PV modules reduce water evaporation and inhibit algae growth, helping to improve water quality. Floating PV power generation devices enhance their resistance to deformation through optimized structural configuration and connection methods, including high-rigidity platforms, flexible connection arrays, and biomimetic flexible structures. The principle of the flexible connection array is that modules are connected by flexible ropes, allowing small independent movements to dissipate energy, thereby achieving resistance to deformation.

[0003] Existing floating photovoltaic power generation devices use buoyancy materials to float the photovoltaic panels on the water surface. The buoyancy materials sway with the waves, causing the photovoltaic panels to sway. This changes the angle at which the photovoltaic panels receive sunlight, and existing devices cannot cope with this swaying, resulting in a decrease in the intensity of sunlight received by the photovoltaic panels and affecting their power generation efficiency. Summary of the Invention

[0004] To overcome the shortcomings mentioned in the background art, the present invention provides a deformation-resistant floating photovoltaic power generation device.

[0005] The technical solution of the present invention is: a deformation-resistant floating photovoltaic power generation device, comprising a mounting plate, an adjustment plate hinged to the upper side of the mounting plate, a photovoltaic panel disposed on the adjustment plate, two mirror-distributed first fixed shells hinged to the upper side of the mounting plate, the first fixed shells being slidably connected to a first sliding rod hinged to the adjustment plate, an airbag fixed to the lower side of the mounting plate, the airbag being connected to two mirror-distributed first connecting pipes, the first connecting pipes being connected to a dual-control connecting shell fixed to the mounting plate, the dual-control connecting shells being connected to a second connecting pipe, the second connecting pipes being connected to the corresponding first fixed shells, and a partition plate fixed to the middle of the airbag.

[0006] Furthermore, it is particularly preferred that the dual-control connecting shell has two gates in a sealed sliding connection, and each gate is fixedly connected with a second sliding rod, which passes through the corresponding dual-control connecting shell.

[0007] Furthermore, it is particularly preferred that the mounting plate is slidably connected with four first sliding members, two of the first sliding members located on the same side of the line connecting the two first fixed shells are jointly fixed with a float, the first sliding members are limited and slidably connected with the corresponding second sliding rods, and there is damping between the first sliding members and the second sliding rods.

[0008] Furthermore, it is particularly preferred that the float is fixedly connected to a third sliding rod passing through the mounting plate, and two third sliding rods are slidably connected to an adjusting rod for limiting. The mounting plate is fixedly connected to a second fixed shell, and the second fixed shell is slidably connected to a second sliding member. The second sliding member is rotatably connected to the adjusting rod, and a spring is provided between the second fixed shell and the second sliding member.

[0009] Furthermore, it is particularly preferred that the adjusting plate is hinged to the photovoltaic panel, and the adjusting plate is hinged to an electric push rod, the telescopic end of which is hinged to the photovoltaic panel.

[0010] Furthermore, it is particularly preferred that two sets of limiting plates are fixedly connected inside the airbag in a mirror-distributed manner, the two sets of limiting plates being located on both sides of the partition plate, and each set of limiting plates consisting of two symmetrically distributed limiting plates.

[0011] Furthermore, it is particularly preferred that the cross-sectional area of ​​the limiting plate gradually decreases from the side closer to the partition plate to the side farther away from the partition plate.

[0012] Furthermore, it is particularly preferred that the adjusting plate is slidably connected to a counterweight, which is used to balance the weight on both sides of the hinge joint between the adjusting plate and the mounting plate.

[0013] Furthermore, it is particularly preferred that the photovoltaic panel is rotatably connected to a mirror-distributed threaded rod, the threaded rod is threadedly connected to a sliding frame that is slidably connected to the photovoltaic panel, the mirror-distributed sliding frames are rotatably connected to a cleaning brush, the photovoltaic panel is fixedly connected to a mirror-distributed motor, and the output shaft of the motor is fixedly connected to the corresponding threaded rod.

[0014] Furthermore, it is particularly preferred that the photovoltaic panel is fixedly connected to a rack with a mirror-distributed arrangement, and the cleaning brush is fixedly connected to a gear with a mirror-distributed arrangement, the gear meshing with the corresponding rack.

[0015] The beneficial effects of the above solution are as follows: When the airbag is squeezed by waves, the gas inside the airbag is forced into the first fixed shell and pushes the first sliding rod to move, thereby adjusting the angle of the adjustment plate so that the direction of rotation of the adjustment plate is opposite to the direction of rotation of the mounting plate, thereby reducing the angle of rotation of the photovoltaic panel, ensuring the intensity of sunlight received by the photovoltaic panel, maintaining the efficiency of power generation, and avoiding deformation of the mounting plate when it is impacted by waves through flexible connection.

[0016] By using floats to determine the direction of waves and using airbags and floats to buffer waves moving in different directions, the swaying of photovoltaic panels is reduced, ensuring the efficiency of power generation.

[0017] The surface of the photovoltaic panel is cleaned by a cleaning brush to prevent excessive impurities from affecting the intensity of sunlight, thus ensuring the normal operation of the photovoltaic panel. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] When the existing device is in use, it will sway with the waves on the water surface. This swaying causes the angle at which the photovoltaic panel receives sunlight to change, which reduces the intensity of sunlight received by the photovoltaic panel and affects the power generation efficiency of the photovoltaic panel.

[0026] A deformation-resistant floating photovoltaic power generation device, such as Figures 1-3 As shown, the system includes a mounting plate 1 with connecting rings around its perimeter, allowing for interconnection via flexible ropes. An adjusting plate 2 is hinged to the upper side of the mounting plate 1, and a photovoltaic panel 3 is mounted on the upper side of the adjusting plate 2. The photovoltaic panel 3 generates electricity. When the mounting plate 1 rotates, the adjusting plate 2 rotates in the opposite direction, thus reducing the rotation of the photovoltaic panel 3. Two first fixed shells 4, mirror-image distributed to the left and right, are hinged to the upper side of the mounting plate 1. The two first fixed shells 4 are located on the left and right sides of the hinge point between the mounting plate 1 and the adjusting plate 2, respectively, and are equidistant from the hinge point. A first sliding rod 5, hinged to the adjusting plate 2, is slidably connected to each first fixed shell 4. Both sliding connections are equipped with seals. An airbag 6 is fixedly attached to the lower side of the mounting plate 1. The airbag 6 is filled with high-pressure gas. When the water level changes, the buoyancy of the airbag 6 changes, the external pressure on the airbag 6 changes accordingly, and the air pressure inside the airbag 6 also changes accordingly. The airbag 6 is connected to two first connecting pipes 7 that are mirror-distributed to the left and right. The first connecting pipes 7 are connected to a double-control connecting shell 8 fixedly attached to the mounting plate 1. Gas can only pass through after both of the seals on the double-control connecting shell 8 are unsealed. The double-control connecting shell 8 is connected to a second connecting pipe 9, which is connected to the corresponding first fixed shell 4. A partition plate 10 is fixedly attached to the middle of the airbag 6, dividing the airbag 6 into two equal parts.

[0027] like Figure 3 As shown, the dual-control connecting shell 8 has two gates 11 in a sealed sliding connection. The gates 11 are used to control the connection state of the dual-control connecting shell 8. A second sliding rod 12 is fixedly connected to the gate 11. The second sliding rod 12 passes through the corresponding dual-control connecting shell 8. The second sliding rod 12 consists of a disc and a rod.

[0028] like Figures 1-3 As shown, the mounting plate 1 is slidably connected with four first sliding members 13. The first sliding members 13 are L-shaped. The two first sliding members 13 on the front side and the two first sliding members 13 on the rear side are respectively fixed to a float 14. The float 14 is used to determine the flow direction of the waves. The first sliding members 13 are limited to the corresponding second sliding rods 12 in a sliding connection, and there is damping between the first sliding members 13 and the second sliding rods 12.

[0029] like Figure 3As shown, the float 14 is fixedly connected to a third sliding rod 15 that passes through the mounting plate 1. The third sliding rod 15 consists of a rectangular rod and a round rod. The two third sliding rods 15 are slidably connected to an adjusting rod 16. The mounting plate 1 is fixedly connected to a second fixed shell 17. The second fixed shell 17 is slidably connected to a second sliding member 18. The second sliding member 18 is rotatably connected to the adjusting rod 16. When the waves move from front to back, the wave crest lifts the front float 14, and the rear float 14 is pressed down. The depth of the rear float 14 submerged in the water increases, and the buoyancy it receives increases, thereby balancing the upward force on the front float 14 and reducing the overall tilt of the device. A spring 19 is provided between the second fixed shell 17 and the second sliding member 18. When the float 14 moves, the float 14 will drive the second sliding member 18 to move upward through the third sliding rod 15 and the adjusting rod 16. The second sliding member 18 compresses the spring 19, thereby buffering the movement of the float 14 and reducing the swaying amplitude of the mounting plate 1.

[0030] like Figure 3 As shown, two sets of limiting plates 21 are fixed inside the airbag 6, which are distributed in a mirror image. There are two limiting plates 21 on each side of the partition plate 10. Each set of limiting plates 21 consists of two limiting plates 21 that are symmetrically distributed front and back. The cross-sectional area of ​​the limiting plates 21 gradually decreases from the side closer to the partition plate 10 to the side farther away from the partition plate 10. The limiting plates 21 are used to limit the degree of compression of the airbag 6. When the wave crest is located at the edge of the mounting plate 1, the tilt angle of the mounting plate 1 is the largest. At this time, the angle adjustment of the adjusting plate 2 by the airbag 6 is the largest. When the wave crest moves towards the middle of the mounting plate 1, the tilt angle of the mounting plate 1 gradually decreases. At this time, the degree of compression of the airbag 6 gradually decreases under the limitation of the limiting plates 21. At this time, the angle adjustment of the adjusting plate 2 by the airbag 6 is the smallest. Thus, the rotation of the adjusting plate 2 changes with the tilt of the mounting plate 1, reducing the shaking of the photovoltaic panel 3.

[0031] like Figure 2 As shown, the adjusting plate 2 is slidably connected to a counterweight 22. The counterweight 22 is used to balance the weight on both sides of the hinge between the adjusting plate 2 and the mounting plate 1, so that the center of gravity of the adjusting plate 2 is located at the hinge between it and the mounting plate 1.

[0032] When using this device, first, the mounting plate 1 is placed in the water and connected by the connecting ring to form a rectangular array of evenly arranged mounting plates 1. By adjusting the position of the counterweight 22, the center of gravity of the adjusting plate 2 is located at its hinge point with the mounting plate 1. Then, power can be generated through the photovoltaic panel 3. During the power generation process, when waves move to the left or right side of the mounting plate 1, taking the wave from left to right as an example, the wave crest is initially located on the left side of the mounting plate 1, and the wave trough is located on the right side of the mounting plate 1. Then, the wave crest and wave trough gradually move to the right until the wave trough is located on the left side of the mounting plate 1 and the wave crest is located on the right side of the mounting plate 1. At this point, the impact of a wave on the device ends. During this process, the wave will cause the entire device to swing to the right first and then to the left. When the wave moves, it first pushes the two floats 14 upward and squeezes the left side of the airbag 6. The floats 14 drive the first sliding member 13 upward, the first sliding member 13 drives the second sliding rod 12 to move, and the second sliding rod 12 drives the gate 11 to move, thereby connecting the two dual-control connecting shells 8. At this time, the left side of the airbag 6 is squeezed by the wave, the space inside shrinks and the air pressure increases. At the same time, the air pressure is transmitted to the first fixed shell 4 through the first connecting pipe 7, the double-control connecting shell 8 and the second connecting pipe 9 on the left side, pushing the first sliding rod 5 on the left side to move downward. The first sliding rod 5 pulls the left side of the adjusting plate 2 to move downward. The adjusting plate 2 drives the photovoltaic panel 3 to rotate, thereby partially offsetting the shaking caused by the wave pushing the device, maintaining the light intensity received by the photovoltaic panel 3 and ensuring power generation efficiency. During the movement of the wave, the rightward tilt of the device caused by the movement of the wave crest gradually decreases. The airbag 6 is blocked by the limiting plate 21, and the amount of deformation of the compressed position of the airbag 6 gradually decreases, thereby reducing the corresponding swing of the adjusting plate 2. When the wave crest passes the partition plate 10 and reaches the right side of the airbag 6, the device tilts to the left and the angle gradually increases. At the same time, the right side of the airbag 6 is squeezed by the wave, and the compressed volume also gradually increases, thereby driving the adjusting plate 2 to swing to the right and maintain the angle of the photovoltaic panel 3.

[0033] When aquatic animals such as fish collide with the airbag 6, the impact force is small, so the device as a whole is unlikely to swing. However, the airbag 6 is compressed. At this time, the float 14 does not move, so the dual-control connecting shell 8 remains sealed. Therefore, the airbag 6 will not drive the adjusting plate 2 for adjustment. When aquatic animals such as fish collide with the float 14, taking the front float 14 as an example, the front float 14 moves upward. The float 14 drives the third sliding rod 15 to move. The third sliding rod 15 drives the adjusting rod 16 to rotate. The rear side of the adjusting rod 16 presses down on the rear third sliding rod 15, and the rear third sliding rod 15 presses down on the rear float 14. 4. The volume of the rear float 14 submerged in water increases, resulting in increased buoyancy. This balances the impact force of fish on the front float 14, causing the entire device to move upward and reducing the swaying amplitude. When the float 14 moves, it will drive the second sliding member 18 to move upward through the third sliding rod 15 and the adjusting rod 16. The second sliding member 18 compresses the spring 19, thereby buffering the movement of the float 14 and reducing the swaying amplitude of the mounting plate 1. The above working principle also applies when there are waves from front to back or from back to front, thereby maintaining the intensity of sunlight received by the photovoltaic panel 3 and ensuring the power generation efficiency of this device.

[0034] Example 2

[0035] Based on Example 1, such as Figure 1 and Figure 2 As shown, the adjustment plate 2 is hinged to the photovoltaic panel 3, and the adjustment plate 2 is hinged to an electric push rod 20. The telescopic end of the electric push rod 20 is hinged to the photovoltaic panel 3. The angle of the photovoltaic panel 3 can be adjusted by the electric push rod 20 so that the photovoltaic panel 3 faces the direction of sunlight, thereby improving the power generation efficiency of the photovoltaic panel 3.

[0036] Example 3

[0037] Based on Example 1, such as Figure 1 , Figure 2 and Figure 4 As shown, the photovoltaic panel 3 is rotatably connected to two threaded rods 23 that are mirror-distributed in front and behind. The threaded rods 23 are threadedly connected to sliding frames 24 that are slidably connected to the photovoltaic panel 3. When the threaded rods 23 rotate, the sliding frames 24 slide along the photovoltaic panel 3 through the threaded transmission. The two sliding frames 24 are rotatably connected to a cleaning brush 25, which is used to clean impurities on the surface of the photovoltaic panel 3. The photovoltaic panel 3 is fixedly connected to two motors 26 that are mirror-distributed in front and behind. The output shafts of the motors 26 are fixedly connected to the corresponding threaded rods 23.

[0038] like Figure 1 and Figure 4As shown, the photovoltaic panel 3 is fixed with two racks 27 that are distributed in a mirror image. The cleaning brush 25 is fixed with a gear 28 that is distributed in a mirror image. The gear 28 meshes with the corresponding rack 27. The rack 27 is located on the upper side of the cleaning brush 25. When the cleaning brush 25 moves to the left, the gear 28 will rotate clockwise, thereby enhancing the cleaning effect of the cleaning brush 25 on the photovoltaic panel 3.

[0039] When impurities on the photovoltaic panel 3 affect the power generation efficiency, the two motors 26 start. The output shaft of the motor 26 drives the threaded rod 23 to rotate. The threaded rod 23 moves through the threaded transmission sliding frame 24. The sliding frame 24 drives the cleaning brush 25 to move. When the cleaning brush 25 moves, because the rack 27 meshes with the gear 28, the cleaning brush 25 will rotate, thereby cleaning the photovoltaic panel 3 to maintain the normal use of the photovoltaic panel 3.
