Description

Technical Field

[0001] The present invention relates to the technical field of protective structures, and particularly to a floating photovoltaic device with a protective function. Background Art

[0002] Floating photovoltaic devices have significant advantages, especially in terms of saving land resources. They can not only effectively utilize the water area space for power generation but also reduce the evaporation of water bodies by blocking sunlight, thus playing a positive role in water resource protection. However, when such devices are installed on the sea surface, they face a series of technical challenges. Firstly, the impact of ocean waves causes the photovoltaic devices to shake, affecting their stability, and long-term shaking may damage the device structure. Secondly, when ocean waves slap the devices, the splashed seawater easily crosses the floating devices and adheres to the surface of the photovoltaic panels. As the seawater evaporates, salt crystals gradually accumulate on the surface of the photovoltaic panels, not only reducing their power generation efficiency but also corroding the surface of the photovoltaic panels and the bracket materials, thereby shortening the service life of the devices.

[0003] For example, the patent (CN 220701299 U) discloses a protection for a construction platform of floating photovoltaics, including a base. A guardrail is fixedly connected to the top end of the base. The guardrail and the base together form a support structure, and through grooves are linearly arranged inside the guardrail. A buoyancy component is fixedly connected to the bottom end surface of the base, solving the problem that when the existing construction platform malfunctions, it is easy to cause workers or photovoltaic components to fall into the water. The utility model can achieve stable support for the base by using the buoyancy component arranged on the bottom end surface of the base, and can achieve efficient protective operation through the guardrail fixedly connected to the top end surface of the base, which is beneficial to safe construction.

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: The prior art is not convenient for positioning floating photovoltaic devices. Due to the pushing of ocean waves on the floating photovoltaic devices, the floating photovoltaic devices are not stable enough to provide a stable photovoltaic absorption effect. Therefore, the prior art lacks a mechanism for shaking according to the size of ocean waves and effectively buffering the swinging amplitude of the photovoltaic panels according to the size of ocean waves, thereby effectively improving the stability of the photovoltaic panels. For this reason, we design a floating photovoltaic device with a protective function to provide another technical solution to the above technical problems. Summary of the Utility Model

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] As described in the background art, it is inconvenient to position the floating photovoltaic device in the prior art. Due to the pushing of the floating photovoltaic device by the sea waves, the floating photovoltaic device is not stable enough to provide a stable photovoltaic absorption effect. Therefore, the prior art lacks a device that can shake according to the size of the sea waves and effectively buffer the swing amplitude of the photovoltaic panel according to the size of the sea waves, thereby effectively improving the stability of the photovoltaic panel.

[0023] To solve this technical problem, the present utility model provides a floating photovoltaic device with a protection function.

[0024] Specifically, please refer to Figures 1-10 , a floating photovoltaic device with a protection function specifically includes: It includes a floating platform 1. A plurality of support columns 3 are fixed on the outer side of the top end of the floating platform 1. As the basic support structure of the entire floating photovoltaic device, the floating platform 1 ensures that the entire device can float stably on the water surface. The top end of the support column 3 is fixed with a support plate 5, and the top end of the support plate 5 is fixed with a photovoltaic panel 2. The photovoltaic panel is composed of a plurality of photovoltaic cells. When sunlight shines on the photovoltaic cells, photons will excite the electrons in the cells, thereby generating an electric current. The conversion efficiency of the photovoltaic panel depends on factors such as its material, process, and structure. A plurality of buoyancy rings 7 are fixed at the bottom end of the floating platform 1. A plurality of L-shaped frames 4 are slidably connected to the outer side of the inside of the floating platform 1. The bottom ends of the plurality of L-shaped frames 4 are fixed with guide cylinders 9, and a telescopic cylinder 10 is slidably connected to the inside of the guide cylinder 9. The top end of the telescopic cylinder 10 is fixed to the floating platform 1.

[0025] When the floating photovoltaic device with a protection function provided by the present utility model is in use, when the device is placed on the sea, the photovoltaic panel 2 is assembled above the support plate 5. At this time, the floating platform 1 floats on the water surface, and at this time, the L-shaped frames 4, buoyancy cylinders 8, guide cylinders 9, and telescopic cylinders 10 are submerged under the water surface. When the sea waves push the floating platform 1, at this time, the L-shaped frames 4 slide with the floating platform 1, and finally the floating platform 1 and the photovoltaic panel 2 are pulled back through the L-shaped frames 4, thereby maintaining the stability of the photovoltaic panel 2 and the floating platform 1.

[0029] Embodiment 1 Please refer to Figures 1-10 , a floating photovoltaic device with a protection function, including a floating platform 1. The buoyancy of the floating platform comes from the internal buoyancy structure (such as a buoyancy ring) and the external buoyancy cylinder. The buoyancy ring and the buoyancy cylinder are usually made of lightweight and corrosion-resistant materials such as high-density polyethylene (HDPE) to ensure the stability and durability of the device in water. A number of support columns 3 are fixed on the outer side of the top of the floating platform 1, and a number of buoyancy rings 7 are fixed on the bottom of the floating platform 1. These buoyancy rings provide the necessary buoyancy to keep the floating platform and the structure above it on the water surface. The top of the support column 3 is fixed with a support plate 5. The support column and the support plate are usually made of lightweight and high-strength materials such as aluminum alloy or stainless steel. These materials have good corrosion resistance and wind pressure resistance to ensure the safety of the photovoltaic panel under harsh weather conditions. The top of the support plate 5 is fixed with a photovoltaic panel 2, and a number of buoyancy rings 7 are fixed on the bottom of the floating platform 1. A number of L-shaped frames 4 are slidably connected to the outer side of the inside of the floating platform 1. The L-shaped frames 4 are made of anti-corrosion materials. Buoyancy cylinders 8 are fixed on the outer side of the L-shaped frames 4, which are fixed on the outer side of the L-shaped frames 4 to provide additional buoyancy and help the stability of the device in waves. The bottom ends of a number of L-shaped frames 4 are fixed with guide sliding cylinders 9. A telescopic cylinder 10 is slidably connected to the inside of the guide sliding cylinder 9. The top of the telescopic cylinder 10 is fixed to the floating platform 1, and the top is fixed to the floating platform 1 and slides up and down with the guide sliding cylinder 9. This design enhances the adaptability and stability of the device in waves; When in use, when the device is placed on the sea, and then the photovoltaic panel 2 is assembled above the support plate 5. At this time, the floating platform 1 floats on the water surface, and at this time, the L-shaped frames 4, the buoyancy cylinders 8, the guide sliding cylinders 9 and the telescopic cylinders 10 are submerged under the water surface. When the sea wave pushes the floating platform 1, at this time, the L-shaped frames 4 slide with the floating platform 1, and finally the floating platform 1 and the photovoltaic panel 2 are pulled back through the L-shaped frames 4, so as to maintain the stability of the photovoltaic panel 2 and the floating platform 1; A number of sliding columns 11 are fixed on the outer side between the floating platform 1 and the support plate 5. The inside of the sliding columns 11 is slidably connected to the L-shaped frames 4. A number of sliding grooves 13 are opened on the outer side of the inside of the sliding columns 11. The top ends of the outer sides of the L-shaped frames 4 are all fixed with sliders 12. The outer sides of the sliders 12 are slidably connected to the sliding grooves 13. A return spring 14 is assembled inside the sliding columns 11. The top of the return spring 14 is fixed to the sliding columns 11, and the bottom of the sliding columns 11 is fixed to the L-shaped frames 4; Specifically, when the sea wave pushes the floating platform 1, at this time, the floating platform 1 slides with the L-shaped frames 4. In order to improve the stability of the floating platform 1, at this time, the support plate 5 and the photovoltaic panel 2 are pulled back by the elasticity of the return spring 14, and the floating platform 1 can shake according to the arc of the sea wave, so as to prevent the floating platform 1 from taking in water and avoid the sea water from submerging the photovoltaic panel 2, so as to facilitate the protection of the photovoltaic panel 2; The telescopic cylinder 10 and the guide sliding cylinder 9 slide up and down to facilitate the improvement of the sliding stability of the floating platform 1 and the L-shaped frame 4, thereby strengthening the sliding effect between the floating platform 1 and the L-shaped frame 4. The floating platform 1 sways with the waves, and the L-shaped frame 4, the guide sliding cylinder 9, and the telescopic cylinder 10 effectively pull back the floating platform 1 and the photovoltaic panel 2 through the elasticity of the return spring 14; The design of the sliding column takes into account the requirements of smooth and stable sliding. The return spring utilizes its elastic characteristics to absorb and release energy, so as to ensure that the device can quickly return to a stable state when subjected to external forces; Flow guiding plates 6 are fixedly arranged on the outer sides of the floating platform 1. The flow guiding plates 6 are formed in an arc shape and are fixedly arranged on the outer sides of the floating platform 1 in an arc shape. Their design helps to guide the splashed water back to the sea surface. The water splashing towards the device is effectively guided back through the flow guiding plates 6. At this time, the arc-shaped flow guiding plates 6 effectively prevent sea water from splashing onto the photovoltaic panel 2, so as to facilitate the protection of the photovoltaic panel 2.

The chain is used to connect to the underwater support point to prevent the device from being washed away by the waves. A chain is wound around the outside of the winding roller 16. One end of the chain away from the winding roller 16 passes through the floating platform 1, the telescopic cylinder 10, and the guide sliding cylinder 9 and is fixed with a hook for connecting to the underwater support point to achieve the fixation of the device. A protection box 17 is fixedly arranged at the top of the floating platform 1. One end of the winding roller 16 passes through one of the support plates 15 and is fixed with a worm gear 18. One end of one of the support plates 15 is rotatably connected with a worm 20. One end of one of the support plates 15 is fixedly provided with a servo motor 19. A waterproof sleeve is sleeved outside the servo motor 19. The output end of the servo motor 19 is fixedly connected with the worm 20; Specifically, it is connected to the underwater support point through the hook to prevent the device from being pushed away by the waves. Therefore, the hook is connected to the support point, and then the servo motor 19 is started to drive the worm 20 to rotate. The worm 20 drives the worm gear 18 to rotate. At this time, the worm gear 18 drives the winding roller 16 to pull the chain, so as to pull and fix the support point, and further to limit the device; The design of the winding roller and the chain takes into account the stability and safety requirements of the device. The servo motor utilizes its precise control ability to drive the winding roller to rotate, thereby realizing the precise control of the winding and unwinding of the chain. This mechanism helps to prevent the device from being washed away by the waves and ensures its stability under harsh weather conditions; The usage process of a water-based photovoltaic device with a protection function provided by the present invention is as follows: When the device is placed on the sea, the photovoltaic panel 2 is assembled above the support plate 5. At this time, the floating platform 1 floats on the water surface, and the L-shaped frame 4, buoyancy cylinder 8, guide cylinder 9, and telescopic cylinder 10 are submerged below the water surface. Then, it is connected to the underwater support point through a hook. The servo motor 19 is started to drive the worm 20 to rotate. The worm 20 drives the worm gear 18 to rotate. At this time, the worm gear 18 drives the winding roller 16 to traction the chain, so as to traction and fix the support point, and further limit the device. When the sea wave pushes the floating platform 1, the arc-shaped deflector 6 effectively prevents sea water from splashing onto the photovoltaic panel 2, so as to protect the photovoltaic panel 2. At this time, the floating platform 1 slides with the L-shaped frame 4. To improve the stability of the floating platform 1, the support plate 5 and the photovoltaic panel 2 are pulled back by the elasticity of the return spring 14. The floating platform 1 can shake according to the arc of the sea wave, so as to prevent the floating platform 1 from taking in water and avoid the sea water from submerging the photovoltaic panel 2, so as to protect the photovoltaic panel 2.
