Description

Technical Field

[0001] This utility model relates to the field of photovoltaic new energy technology, specifically a self-cleaning device for nano-coated photovoltaic glass. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, the problem of reduced power generation efficiency caused by surface contamination of photovoltaic modules has become increasingly prominent. To address this challenge, the mainstream solution is to cover the surface of photovoltaic glass with a nano self-cleaning coating. This type of coating can achieve daily cleaning under the wash of rainwater through photocatalysis and superhydrophilic effect, which reduces the adhesion of surface dust to a certain extent. However, this passive self-cleaning method that relies on the natural environment has obvious limitations. For stubborn pollutants such as bird droppings, oil stains, and sticky dust, the decomposition and cleaning ability of the nano coating is seriously insufficient. The continuous accumulation of pollutants will form a blockage, which seriously affects the light transmittance and power generation efficiency.

[0003] To address the aforementioned stubborn dirt, existing technologies often employ manual rinsing or the installation of large-scale spray systems. This not only consumes significant amounts of water and manpower but also fails to provide sustained cleaning effectiveness. Furthermore, the cleaning process may scratch the delicate nano-coating. While some automated cleaning devices can perform periodic cleaning, their rigid bristles or scrapers can easily damage the coating surface, compromising its self-cleaning function. Moreover, they generally lack self-cleaning structures, and dirt adhering to the cleaning components can easily cause secondary pollution. Therefore, we propose a self-cleaning device for nano-coated photovoltaic glass to solve the above problems. Utility Model Content

[0016] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0017] This utility model provides an improved self-cleaning device for nano-coated photovoltaic glass. The technical solution of this utility model is as follows: like Figure 1 - Figure 5As shown, a self-cleaning device for nano-coated photovoltaic glass includes a frame 1. A collection tank 2 is fixedly connected to the inner wall of the frame 1. An L-shaped bracket 3 is fixedly connected to the side wall of the collection tank 2. Two symmetrically arranged strip plates 4 are fixedly connected to the side wall of the collection tank 2. A single side plate 5 is fixedly connected to the side wall of the two strip plates 4. A single photovoltaic module 6 is fixedly connected to the side wall of the two strip plates 4. An adjusting rod 7 is rotatably connected to the side wall of the L-shaped bracket 3. A movable part 8 is sleeved on the surface of the adjusting rod 7. A rotating rod 9 is rotatably connected to the inner wall of the movable part 8. A nano-coated flexible cleaning roller 10 is fixedly connected to the surface of the rotating rod 9. The nano-coated flexible cleaning roller 10 abuts against the upper surface of the photovoltaic module 6. Two symmetrically arranged... Gear 11, two sets of symmetrically arranged racks 12 are fixedly connected to the upper surface of the equipment frame 1, scraper group 13 is fixedly connected to the side wall of the side plate 5, scraper group 13 abuts against the surface of nano-coated flexible cleaning roller 10, dust box 14 is fixedly connected to the side wall of the side plate 5, motor 15 is fixedly connected to the right end of the adjusting rod 7, and collection tank 2 is mainly used to collect natural rainwater to provide the water source required for cleaning and wetting of nano-coated flexible cleaning roller 10. It can make full use of natural resources and achieve energy-saving and environmentally friendly self-cleaning effect. The core cleaning function of this device does not completely rely on rainwater. In dry seasons or waterless environments, a small amount of clean water can be injected into the collection tank 2 by an external micro water pump or manually, which can also achieve the same self-cleaning and wetting function of the cleaning roller.

[0018] Furthermore, the side plate 5 is fixedly connected to the inner wall of the equipment rack 1, and there is a gap between the photovoltaic module 6 and the side wall of the collection tank 2, and a gap between the photovoltaic module 6 and the side wall of the side plate 5. This gap design facilitates the smooth falling of dust and dirt, and avoids accumulation on the edge of the photovoltaic module 6.

[0019] Furthermore, the surface of the adjusting rod 7 is provided with a reciprocating thread, and the adjusting rod 7 is connected to the moving part 8 through the reciprocating thread. By setting the reciprocating thread, the moving part 8 can be driven to automatically perform reciprocating linear motion.

[0020] Furthermore, both ends of the rotating rod 9 penetrate the inner wall of the moving part 8 and extend to the outside of the moving part 8. Each gear 11 is rotatably connected to the side wall of the moving part 8. Through this arrangement, it is ensured that the rotating rod 9 and the gear 11 are stably supported on the moving part 8, and the gear 11 can accurately mesh with the rack 12 to transmit motion.

[0021] Furthermore, each set of racks 12 is meshed with the surface of the adjacent gear 11, the rotating rod 9 is slidably connected to the upper surface of the two strip plates 4, and the two strip plates 4 are slidably connected to the inner wall of the moving part 8. The meshing of the gears 11 and racks 12 realizes the rotation cleaning function of the nano-coated flexible cleaning roller 10, while the sliding connection between the rotating rod 9 and the strip plates 4 plays a guiding and supporting role when the gears 11 and racks 12 are disengaged, ensuring that the surface of the photovoltaic module 6 is uniformly stressed and thoroughly cleaned when the nano-coated flexible cleaning roller 10 moves to clean.

[0022] Furthermore, the right end of the adjusting rod 7 passes through the left side of the side plate 5 and extends into the interior of the dustproof box 14. The motor 15 is fixedly connected to the inner wall of the dustproof box 14. The dustproof box 14 provides a sealed protective space for the motor 15, effectively isolating dust and moisture, and significantly improving the service life and operational reliability of the motor 15.

[0023] Furthermore, the nano-coated flexible cleaning roller 10 is made of high-density flexible sponge material. The surface of the nano-coated flexible cleaning roller 10 has a micro-convex texture structure, which ensures full adhesion to the photovoltaic glass surface. At the same time, the flexible contact avoids physical damage to the nano-coating. This allows the nano-coated flexible cleaning roller 10 to effectively remove stubborn dirt during wiping without damaging the nano-coating structure on the photovoltaic glass surface.

[0024] Working principle: When the nano-coated glass on the surface of the photovoltaic module 6 needs cleaning, the motor 15 is first turned on. The motor 15 drives the adjusting rod 7 to rotate, causing the moving part 8 to move back and forth on the adjusting rod 7. In the initial state, the moving part 8, the rotating rod 9, the nano-coated flexible cleaning roller 10, and the gear 11 are on the far right. The gear 11 meshes with the rack 12 located on the right. When the adjusting rod 7 rotates and drives the moving part 8 to move, because the rack 12 meshes with the gear 11, the gear 11 will rotate on the rack 12. The gear 11 then moves the nano-coated glass through the rotating rod 9. The flexible cleaning roller 10 rotates, and when the nano-coated flexible cleaning roller 10 rotates, it rubs against the scraper assembly 13. As the adjusting rod 7 rotates, the moving part 8 continues to move to the left. When the moving part 8 drives the nano-coated flexible cleaning roller 10 to move to the left until the gear 11 and rack 12 are separated, the gear 11 will no longer rotate. The rotating rod 9 moves on the strip plate 4, and the nano-coated flexible cleaning roller 10 only moves and rubs on the surface of the photovoltaic module 6 to clean the dust on the photovoltaic module 6. When the moving part 8 moves to the left until the gear 11 meshes with the left rack 12, the gear... As the 11th component begins to rotate, when the moving part 8 moves to its leftmost limit position, the nano-coated flexible cleaning roller 10 moves just above the collection tank 2. The nano-coated flexible cleaning roller 10 rotates and enters the collection tank 2, causing the rainwater collected in the collection tank 2 to rub against and wet the surface of the nano-coated flexible cleaning roller 10. While cleaning the nano-coated flexible cleaning roller 10, it also wets it. Then, the adjusting rod 7 drives the moving part 8 to start moving to the right and return. During this return trip, the wetted nano-coated flexible cleaning roller 10 comes into contact with the surface of the photovoltaic module 6 again and performs wet wiping to further remove residual stains. When the moving part 8 returns to the right side with the nano-coated flexible cleaning roller 10, the nano-coated flexible cleaning roller 10 rubs against the fixed scraper group 13 again. The scraper group 13 thoroughly scrapes away the dust and dirt attached to the nano-coated flexible cleaning roller 10 throughout the cleaning process. The scraped dirt falls through the gap between the photovoltaic module 6 and the side plate 5, thus restoring the nano-coated flexible cleaning roller 10 to cleanliness and preparing it for the next cleaning cycle. The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
