Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, specifically a floating photovoltaic power station. Background Technology

[0002] We are familiar with various types of photovoltaic (PV) power plants, including centralized, distributed, tower, rooftop, and agricultural greenhouse types, but these are all ground-mounted PV power plants. However, Earth's land resources are limited, and their usability is ultimately finite. Based on this, a new type of PV power plant has emerged: the floating PV power plant. The development of floating PV power plants primarily utilizes a photovoltaic + water surface model. Currently, the water surface is mainly utilized through ponds, small lakes, reservoirs, and water storage tanks. Floating PV power plants offer advantages such as saving land resources and having a relatively small impact on the aquatic ecosystem.

[0003] In the prior art, a floating photovoltaic power station with publication number "CN209545487U" belongs to the field of photovoltaic power stations. Its key technical features include a supporting floating platform and a walking platform for carrying people, fixedly connected to the supporting floating platform. Solar panels are mounted on the supporting floating platform. A connecting net is fixedly connected between two adjacent supporting floating platforms. The two opposite sides of the connecting net are fixedly connected to the side walls of the two adjacent floating platforms. A wind vane is installed at the highest point of the solar panels, with its rotation axis vertically set. A horizontally set wind whistle is fixedly connected to the top surface of the wind vane, with the length direction of the wind whistle along the length direction of the wind vane, and the rotation axis of the wind vane intersecting the axis of the wind whistle. This floating photovoltaic power station solves the technical problem of bird disturbance that often plagues existing photovoltaic power stations, achieving the effect of dispersing birds near the photovoltaic power station, and can be applied to the construction of floating photovoltaic power stations.

[0004] However, there are still some obvious drawbacks in its use: the device only frightens birds by using a bagpipe to reduce their gathering on the solar panels on the water. This single method of bird deterrence becomes inefficient after the birds adapt, resulting in a decrease in bird deterrence effect. Moreover, the device is completely dependent on wind power. When the wind is intermittent, the bagpipe will also sound intermittently, which reduces the effectiveness of bird deterrence. Summary of the Invention

[0005] The purpose of this invention is to provide a floating photovoltaic power station to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A floating photovoltaic power station includes an anchor plate, on which multiple bearing plates are fixedly mounted. Each bearing plate has a floating airbag fixedly mounted at its bottom. Two bearing plates form a group, and a support rod is fixedly mounted on the top of the bearing plate. A photovoltaic panel is fixedly mounted on the top of the support rod.

[0008] Mounting plates are provided between the bearing plates of adjacent groups. A floating plate is fixedly installed at the bottom of the mounting plate. A base plate is fixedly installed at the top of the mounting plate via a fixing column. An operating box is fixedly installed at the top of the base plate. A hollow rotating rod is hinged inside the operating box. Blades are fixedly installed on the hollow rotating rod. A wind cup is fixedly installed at the end of the blade. A bearing is sleeved on the outside of the hollow rotating rod. Multiple reflective strips are fixedly installed on the outer wall of the bearing. A transparent cover is connected to the top of the hollow rotating rod. Multiple reflective flow-blocking strips are fixedly installed inside the transparent cover. A positioning column is fixedly installed on the base plate. A collar is fixedly installed on the positioning column. Multiple elastic paddles are fixedly installed on the inner ring of the collar. A paddle ball is fixedly installed on the outside of the hollow rotating rod located in the collar via an extension rod.

[0009] A driving bevel gear is fixedly sleeved on the hollow rotating rod, and the driving bevel gear and the driven bevel gear mesh with each other. A central rod is fixedly installed at the center of the driven bevel gear, and a cam is fixedly installed on the central rod. A hollow tube is fixedly installed inside the operating box, and a piston plate is movably installed inside the hollow tube. A connecting rod is fixedly installed on the piston plate, and a pressure plate is fixedly installed on the connecting rod. A limit block is fixedly installed on the outer wall of the hollow tube, and a spring is connected between the pressure plate and the limit block. An inlet is connected to the bottom of the hollow tube. The water pipe includes an inlet pipe with a first one-way valve, a hollow pipe connected to a water tank via a connecting pipe with a second one-way valve, a drip pipe connected to the bottom of the water tank with a first water trough below the drip pipe, a water tank connected to the interior of a transparent cover via a guide pipe with a third one-way valve, a limit bearing fixedly installed inside the transparent cover with the guide pipe passing through the limit bearing, a narrow section at the bottom of the hollow rotating rod with a second water trough below the narrow section.

[0010] Preferably, the end of the mounting plate is fixed to the anchor plate, and the side of the mounting plate is fixed to the side of the bearing plate by a positioning plate.

[0011] Preferably, the hollow rotating rod and its narrow bottom section are integrally formed.

[0012] Preferably, the end of the central rod away from the passive bevel gear is disposed in the bearing housing, and the bearing housing is fixedly disposed on the outer wall of the water storage tank.

[0013] Preferably, a pressure relief pipe is connected to the side of the water storage tank, and a pressure relief valve is installed in the pressure relief pipe.

[0014] Preferably, the first water tank and the second water tank are both fixedly mounted on the positioning plate, and the positioning plate is respectively provided with a first drain hole and a second drain hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention has a bearing sleeved on the outside of the hollow rotating rod, and multiple reflective strips are fixedly installed on the outer wall of the bearing. When the wind speed in the environment is low, the reflective strips are light and easily blown away, so the reflective strips will rotate, thereby dynamically reflecting light onto the photovoltaic panels on both sides, which can play a role in repelling birds.

[0017] 2. This invention features blades fixedly mounted on a hollow rotating rod, with wind cups fixedly mounted at the ends of the blades. When the wind speed is high, the wind blows the wind cups, causing the hollow rotating rod to rotate. At this time, on the one hand, the actuating ball rotates and actuates the elastic lever, causing the elastic lever to make a sound, which serves to scare away birds. On the other hand, the cam is driven to intermittently press down the pressure plate, causing the water tank to continuously fill with water. The water flows out from the drip pipe and hits the first water tank, making a sound. Furthermore, the water dynamically enters the transparent cover, filling it with water and focusing light. This not only creates dynamic light reflection when the transparent cover rotates, which can startle and scare away birds, but also improves the photoelectric conversion efficiency of the photovoltaic panel after the transparent cover is filled with water and focuses light onto it. Finally, the water in the transparent cover flows out through the narrow opening and hits the second water tank, making a sound again. Therefore, even after the wind stops, the water in the water tank will continue to drip for a period of time, making up for the disadvantage of poor bird-scaring effect when there is no wind.

[0018] This invention provides a floating photovoltaic power station that can automatically employ different dynamic bird-repelling methods under conditions of low wind, high wind, and no wind, avoiding birds from adapting to a single bird-repelling method. Moreover, when repelling birds, it can both use concentrated light to disturb them and increase the light intensity on the photovoltaic panels, resulting in better performance.

[0025] 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.

[0026] Please see Figures 1 to 5 The present invention provides a technical solution:

[0027] Example 1:

[0028] A floating photovoltaic power station includes an anchor plate 1, which is a basic positioning and anchoring component. Multiple bearing plates 2 are fixedly installed on the anchor plate 1. Each bearing plate 2 has a floating airbag 3 fixedly installed at its bottom. The floating airbag 3 allows the bearing plate 2 to float stably on the water surface. Two bearing plates 2 form a group, and a support rod 4 is fixedly installed on the top of the bearing plate 2. A photovoltaic panel 5 is fixedly installed on the top of the support rod 4. The height of the support rod 4 is not uniform, and the photovoltaic panel 5 can be placed at an angle, so that impurities and dirt are not easily attached to the surface of the photovoltaic panel 5.

[0029] Mounting plates 6 are installed between adjacent support plates 2. A floating plate 8 is fixed to the bottom of each mounting plate 6, allowing it to float stably on the water surface. A base plate 10 is fixed to the top of each mounting plate 6 via a fixing column 9. An operating box 11 is fixed to the top of the base plate 10. A hollow rotating rod 12 is hinged inside the operating box 11, with blades 13 fixed to it. A wind cup 14 is fixed to the end of each blade 13. When the wind speed is high, the wind will blow the wind cup 14, which in turn will cause the hollow rotating rod 12 to rotate via the blades 13. A bearing 15 is fitted on the outer side of the hollow rotating rod 12, and multiple reflective strips 16 are fixed to the outer wall of the bearing 15. The reflective strips 16 are lightweight, and even when the wind speed is low, the wind can easily blow them, causing them to rotate and generate dynamic light reflection. This can disturb birds near the photovoltaic panel 5, preventing them from... Bird droppings will damage the photovoltaic panel 5 after the bird stops. A transparent cover 17 is connected to the top of the hollow rotating rod 12. Multiple reflective flow-blocking strips 18 are fixedly installed inside the transparent cover 17. The reflective flow-blocking strips 18 can not only block the flow of liquid inside the transparent cover 17 and slow down its flow speed, but also make the transparent cover 17 generate different shapes of light reflection when it rotates as a whole due to their random arrangement, making it more dynamic and thus effectively improving the bird-repelling effect. A positioning post 19 is fixedly installed on the base plate 10. A collar 20 is fixedly installed on the positioning post 19. Multiple elastic paddles 21 are fixedly installed on the inner ring of the collar 20. A toggle ball 23 is fixedly installed on the outside of the hollow rotating rod 12 in the collar 20 through the extension rod 22. As the hollow rotating rod 12 rotates, the toggle ball 23 will sequentially paddle the elastic paddles 21. The elastic paddles 21 can undergo elastic deformation and generate vibration after deformation and recovery, so as to achieve the effect of noise to repel birds.

[0030] Example 2:

[0031] Based on Embodiment 1 above, this embodiment adds the following structure: A driving bevel gear 24 is fixedly sleeved on the hollow rotating rod 12, and the driving bevel gear 24 and the driven bevel gear 25 are meshed together. A central rod 26 is fixedly installed at the center of the driven bevel gear 25. When the driving bevel gear 24 rotates, it can drive the central rod 26 to rotate through the driven bevel gear 25. A cam 27 is fixedly installed on the central rod 26, thereby driving the cam 27 to rotate continuously. A hollow tube 29 is fixedly installed inside the operating box 11, and a piston plate 30 is movably installed inside the hollow tube 29. The piston plate 30 can fit against the inner wall of the hollow tube 29 to achieve... The piston plate 30 moves up and down, and a connecting rod 31 is fixedly installed on the piston plate 30. A pressure plate 32 is fixedly installed on the connecting rod 31. A limit block 33 is fixedly installed on the outer wall of the hollow tube 29, and a spring 34 is connected between the pressure plate 32 and the limit block 33. The spring 34 has good elasticity, so when the cam 27 rotates to the position where it no longer presses down on the pressure plate 32, the pressure plate 32 will be lifted to the initial position by the spring 34. A water inlet pipe 35 is connected to the bottom of the hollow tube 29, and a first one-way valve 36 is installed in the water inlet pipe 35. The first one-way valve 36 ensures that water below the water surface can only enter the hollow tube 29 through the water inlet pipe 35 and cannot flow backward. Hollow tube 29 is connected to water tank 38 via connecting pipe 37. Water tank 38 stores water for dripping to generate noise to scare away birds and for focusing light to enhance illumination. A second one-way valve 39 is installed in connecting pipe 37, ensuring that water in hollow tube 29 can only enter water tank 38 through connecting pipe 37 and cannot flow backwards. A drip pipe 42 is connected to the bottom of water tank 38, and a first water trough 43 is located below drip pipe 42. Water from drip pipe 42 drips into the first water trough 43, making a sound upon impact to scare away birds. Water tank 38 is connected to the interior of transparent cover 17 via guide pipe 44. A third one-way valve 45 is provided in section 4. The third one-way valve 45 ensures that the water in the water tank 38 can only enter the interior of the transparent cover 17 through the guide pipe 44 and cannot flow backward. A limit bearing 46 is fixedly installed inside the transparent cover 17, and the guide pipe 44 passes through the limit bearing 46. Therefore, the transparent cover 17 can rotate smoothly in place without interfering with the fixed guide pipe 44. A narrow section 121 is provided at the bottom of the hollow rotating rod 12. A second water tank 47 is provided below the narrow section 121. Water will drip from the narrow section 121 of the hollow rotating rod 12, which will then hit the second water tank 47, thus producing noise to repel birds.

[0032] Example 3:

[0033] A floating photovoltaic power station includes an anchor plate 1, which is a basic positioning and anchoring component. Multiple bearing plates 2 are fixedly installed on the anchor plate 1. Each bearing plate 2 has a floating airbag 3 fixedly installed at its bottom. The floating airbag 3 allows the bearing plate 2 to float stably on the water surface. Two bearing plates 2 form a group, and a support rod 4 is fixedly installed on the top of the bearing plate 2. A photovoltaic panel 5 is fixedly installed on the top of the support rod 4. The height of the support rod 4 is not uniform, and the photovoltaic panel 5 can be placed at an angle, so that impurities and dirt are not easily attached to the surface of the photovoltaic panel 5.

[0034] Each set of bearing plates 2 is provided with an installation plate 6. The end of the installation plate 6 is fixed to the anchor plate 1, and the side of the installation plate 6 is fixed to the side of the bearing plate 2 by the positioning plate 7. In this way, the installation plate 6 is fixed in multiple directions, making the photovoltaic power station more stable. A floating plate 8 is fixedly provided at the bottom of the installation plate 6, so that the installation plate 6 can float stably on the water surface. The top of the installation plate 6 is fixedly provided with a base plate 10 by the fixing column 9. An operation box 11 is fixedly provided on the top of the base plate 10. The operation box 11 is internally hinged and hollow. The hollow rotating rod 12 and its narrow bottom section 121 are integrally formed, which facilitates manufacturing, makes the whole more robust, and prevents loosening at the joint. A blade 13 is fixedly mounted on the hollow rotating rod 12, and a wind cup 14 is fixedly mounted at the end of the blade 13. When the wind speed in the environment is high, the wind will blow the wind cup 14, which in turn drives the hollow rotating rod 12 to rotate through the blade 13. A bearing 15 is sleeved on the outer side of the hollow rotating rod 12, and multiple reflective strips 16 are fixedly mounted on the outer wall of the bearing 15. The reflective strips 16 are lightweight, and when the wind speed in the external environment increases... Even at low speeds, the wind can easily blow the reflective strip 16, causing it to rotate and generate dynamic light reflection. This can disturb birds near the photovoltaic panel 5, preventing them from droppings on the panel and damaging it. A transparent cover 17 is connected to the top of the hollow rotating rod 12. Multiple reflective flow-blocking strips 18 are fixedly installed inside the transparent cover 17. These strips not only obstruct the flow of liquid inside the transparent cover 17, slowing its speed, but also, due to their random arrangement, create different shapes when the transparent cover 17 rotates. The light reflection is more dynamic, thus effectively improving the bird-repelling effect. A positioning post 19 is fixedly installed on the base plate 10, and a collar 20 is fixedly installed on the positioning post 19. Multiple elastic paddles 21 are fixedly installed on the inner ring of the collar 20. A paddle ball 23 is fixedly installed on the outside of the hollow rotating rod 12 in the collar 20 through the extension rod 22. As the hollow rotating rod 12 rotates, the paddle ball 23 will sequentially paddle the elastic paddles 21. The elastic paddles 21 can undergo elastic deformation and produce vibration after deformation and recovery, thus achieving the effect of noise-based bird repelling.

[0035] A driving bevel gear 24 is fixedly sleeved on the hollow rotating rod 12. The driving bevel gear 24 and the driven bevel gear 25 are meshed together. A central rod 26 is fixedly installed at the center of the driven bevel gear 25. When the driving bevel gear 24 rotates, it can drive the central rod 26 to rotate through the driven bevel gear 25. A cam 27 is fixedly installed on the central rod 26. Thus, the central rod 26 drives the cam 27 to rotate continuously. The end of the central rod 26 away from the driven bevel gear 25 is set in a bearing seat 28, and the bearing seat 28 is fixedly installed on the outer wall of the water tank 38. The bearing seat 28 allows the central rod 26 to rotate smoothly without jamming. A hollow tube 29 is fixedly installed inside the operating box 11, and a piston plate is movably installed inside the hollow tube 29. 30. The piston plate 30 can move up and down against the inner wall of the hollow tube 29. A connecting rod 31 is fixedly installed on the piston plate 30, and a pressure plate 32 is fixedly installed on the connecting rod 31. A limit block 33 is fixedly installed on the outer wall of the hollow tube 29, and a spring 34 is connected between the pressure plate 32 and the limit block 33. The spring 34 has good elasticity, so when the cam 27 rotates to the position where it no longer presses down on the pressure plate 32, the pressure plate 32 will be lifted to the initial position by the spring 34. A water inlet pipe 35 is connected to the bottom of the hollow tube 29. A first one-way valve 36 is installed in the water inlet pipe 35. The first one-way valve 36 ensures that water below the water surface can only enter the hollow tube 29 through the water inlet pipe 35 and cannot flow backward. The hollow tube 29 is connected to the connecting pipe 37. Connected to a water tank 38, which stores water for dripping to generate noise to scare away birds and for focusing light to enhance illumination, a second one-way valve 39 is installed in the connecting pipe 37. This second one-way valve 39 ensures that water in the hollow tube 29 can only enter the water tank 38 through the connecting pipe 37 and cannot flow backwards. A drip pipe 42 is connected to the bottom of the water tank 38, and a first water trough 43 is located below the drip pipe 42. Water from the drip pipe 42 drips into the first water trough 43, making a sound upon impact, thus scare away birds. The water tank 38 is connected to the interior of a transparent cover 17 via a guide pipe 44, which is equipped with a third one-way valve 45. This third one-way valve 45 ensures that water in the water tank 38 can only enter the water tank 38 through the guide pipe 44. 4. Water enters the interior of the transparent cover 17 and cannot flow backwards. A limit bearing 46 is fixedly installed inside the transparent cover 17, and the guide pipe 44 passes through the limit bearing 46. Therefore, the transparent cover 17 can rotate smoothly in place without interfering with the fixed guide pipe 44. The bottom of the hollow rotating rod 12 is provided with a narrow opening 121, and a second water tank 47 is provided below the narrow opening 121. Water drips from the narrow opening 121 of the hollow rotating rod 12, which then hits the second water tank 47, producing a noise-repelling effect for birds. The first water tank 43 and the second water tank 47 are both fixedly installed on the positioning plate 7, and the positioning plate 7 is respectively provided with a first drain hole 701 and a second drain hole 702. Water overflowing from the first water tank 43 and the second water tank 47...It can flow back to the water surface where the photovoltaic power station is located through the first drain hole 701 and the second drain hole 702.

[0036] Example 4:

[0037] Based on Embodiment 2 or Embodiment 3 above, this embodiment adds the following structure: a pressure relief pipe 40 is connected to the side of the water storage tank 38, and a pressure relief valve 41 is installed in the pressure relief pipe 40. When the water storage tank 38 accumulates a large amount of water, and the pressure exceeds the water pressure value, the pressure relief valve 41 automatically opens and automatically closes after the pressure is reduced, thereby draining the excess water in the water storage tank 38 through the pressure relief pipe 40, preventing the water storage tank 38 from expanding and being damaged due to excessive internal water volume.

[0038] Working principle:

[0039] During use, the photovoltaic panel 5 is installed at an angle on the support rod 4 to receive more sunlight. However, because there are fish and shrimp underwater, birds may feed on them and land on the photovoltaic panel 5. Their droppings will not only contaminate the photovoltaic panel 5 but may also damage it. Therefore, this device is equipped with a bird-repelling structure, specifically:

[0040] When the wind speed in the external environment is low, the wind will blow the lightweight reflective strips 16, causing multiple reflective strips 16 to rotate around the hollow rotating rod 12, thereby dynamically reflecting light onto the photovoltaic panels 5 on both sides, which serves to repel birds.

[0041] When the wind speed in the external environment is high, the wind will blow the wind cup 14. The wind cup 14 drives the hollow rotating rod 12 to rotate through the blade 13. At this time, on the one hand, the hollow rotating rod 12 drives the actuating ball 23 through the extension rod 22, causing the actuating ball 23 to rotate and actuate the elastic paddle 21, causing the elastic paddle 21 to make a sound, which serves to scare away birds with noise. On the other hand, the active bevel gear 24 on the hollow rotating rod 12 will rotate synchronously. The active bevel gear 24 drives the central rod 26 to rotate through the passive bevel gear 25, causing the cam 27 to rotate continuously. When the cam 27 presses down on the pressure plate 32, the pressure plate 32 pushes the piston plate 30 through the connecting rod 31, so that the liquid in the hollow tube 29 is squeezed into the water tank 38 through the connecting pipe 37. When the cam 27 rotates away from the pressure plate 32, the pressure plate 32 will be pushed back to the initial position under the action of the spring 34 to suck water. Thus, under the intermittent squeezing of the cam 27, the water in the water tank 38 will accumulate more and more.

[0042] When there is wind, water will accumulate in the water tank 38, and the water will drip from the drip pipe 42 at the bottom of the water tank 38, hitting the first water tank 43 and generating noise. In addition, when the water in the water tank 38 accumulates to a certain level, but not enough to exceed the predetermined value of the pressure relief valve 41, the water will enter the interior of the transparent cover 17 through the guide pipe 44, making the interior filled with water and focusing light. Multiple reflective flow-blocking strips 18 are randomly and fixedly installed inside the transparent cover 17, which can both block the flow of liquid inside the transparent cover 17 and slow down its flow speed. Because of its random arrangement, the transparent cover 17 produces light reflections of different shapes when it rotates as a whole, making it more dynamic and able to startle and scare away birds. In addition, after the transparent cover 17 is filled with water and focuses light onto the photovoltaic panel 5, it can also improve the photoelectric conversion efficiency of the photovoltaic panel 5. Finally, the water in the transparent cover 17 flows out through the narrow opening 121 of the hollow rotating rod 12 and hits the second water tank 47, making a sound again. Therefore, even after the wind stops, the water in the water tank 38 will continue to drip for a period of time, making up for the disadvantage of poor bird-scare effect when there is no wind.

[0043] Therefore, this device combines multiple bird-repelling methods, avoiding the habitual adaptation of birds caused by a single fixed method. This allows the device to repel birds in light wind, strong wind, and no wind. Moreover, when repelling birds, the device can both use focused light to startle birds and increase the light intensity on the photovoltaic panel 5, resulting in a higher photoelectric conversion rate and better performance.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
