Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panels, and more particularly to a solar photovoltaic panel cleaning device. Background Art

[0002] At present, due to their working characteristics, solar photovoltaic panels need to be installed outdoors to receive sunlight and convert light energy into electrical energy. While receiving sunlight, they will absorb a large amount of dust in the air, especially in areas in northern my country where sandstorms are frequent. The gradual thickening of dust will seriously affect the solar photovoltaic panels' absorption rate of sunlight, and the power generation will gradually decrease. It is necessary to manually remove dust from the solar panels regularly. Moreover, solar photovoltaic panels installed at high altitudes, such as solar street lights and rooftop solar power supply devices, require auxiliary climbing equipment for dust removal. The dust removal process is very inconvenient and difficult.

[0003] Chinese patent publication number CN208369528U discloses a solar photovoltaic panel cleaning device, which consists of two slide rails, a sliding plate, and a vent pipe. The slide rails are located on either side of the solar photovoltaic panel. Sliders slide on the rails, driving the sliding plate to slide directly above the panel. Simultaneously, air is blown into the vent cavity through vent holes, and the air jet outlet ejects air, removing dust deposited on the surface of the solar photovoltaic panel, thereby significantly improving the solar energy absorption efficiency of the solar photovoltaic panel. This technical solution is simple and has excellent dust removal effects.

[0004] Although this solar photovoltaic panel cleaning device improves cleaning efficiency, in actual applications of photovoltaic panels, especially photovoltaic systems installed on curved roofs, the cleaning effect is often unsatisfactory. Due to the unique shape and location of such roofs, birds easily roost, resulting in a large amount of bird droppings on the surface of photovoltaic panels. These biological stains have a particularly serious impact on photovoltaic panels because they not only block sunlight and reduce the amount of light received by the panels, but their chemical components may also react with the surface of the photovoltaic panels, causing permanent damage.

[0005] Traditional cleaning equipment is typically designed to remove general dust and sand. It is less effective against highly adherent and complex contaminants like bird droppings. Failure to effectively remove bird droppings can continuously obstruct light transmittance, significantly reducing the efficiency of photovoltaic panels. Studies have shown that even a thin layer of dust can reduce the efficiency of photovoltaic panels by up to 25%. The obstruction caused by bird droppings is significantly more severe, potentially leading to even greater efficiency losses.

[0006] In addition, long-term accumulation of bird droppings will increase the risk of hot spot effect of photovoltaic panels. When part of the area is blocked, the electricity generated in that area is reduced, but other unblocked areas still work normally. This will cause heat accumulation when current passes through the blocked area, thereby damaging the battery cells and even causing fire hazards. Summary of the Invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

A cleaning wheel 11 is fixedly mounted on the outer surface of the cleaning plate 14, and a cleaning wheel 11 is fixedly mounted on the outer surface of the cleaning plate 14.

[0031] There are two corresponding groups of transmission plates 6 and scrapers 9, and they are symmetrically arranged. A spring 7 is fixedly installed between the two groups of transmission plates 6.

[0032] A wedge block 8 is provided between the two groups of transmission plates 6 , and the wedge block 8 is fixedly installed between the two groups of top blocks 5 .

[0033] When it is necessary to clean the bird droppings and the like on the photovoltaic panels 3, the telescopic rod 4 is started to lower the top block 5, and the lowering of the top block 5 drives the two sets of transmission plates 6 to lower. A spring 17 is provided between the two sets of transmission plates 6, and the scraper 9 at the end of the transmission plate 6 is pressed against the photovoltaic panels 3 under the action of the spring 17. As the top block 5 continues to descend, the scraper 9 at the end of the transmission plate 6 will keep pressing against the photovoltaic panels 3 and continue to advance, thereby cleaning the garbage thereon. At the same time, the internal rotation of the scraper 9 is connected to the rotating shaft 10, and the gear 12 on the rotating shaft 10 is engaged with the rack 13. Therefore, the rotating shaft 10 will rotate when following the displacement of the scraper 9, and carry the cleaning wheel 11 to rotate for cleaning.

[0034] An auxiliary part is provided on the upper side of the scraper 9. The auxiliary part includes a magnetic block 14 fixedly installed inside the cleaning wheel 11. The magnetic blocks 14 are provided in multiple groups and are dispersedly arranged in a ring shape.

[0035] A slot 15 is provided inside the scraper 9, and a transmission rod 16 is provided inside the slot 15. A spring 2 17 is fixedly installed between the upper end surface of the transmission rod 16 and the inner wall of the slot 15. A magnetic strip 18 is provided between the cleaning wheel 11 and the scraper 9, and the upper end of the transmission rod 16 is fixedly connected to the magnetic strip 18.

[0036] The transmission rod 16 is arranged in an L shape. An auxiliary plate 19 is provided on the upper side of the scraper 9 . The upper end of the auxiliary plate 19 is fixedly connected to the transmission rod 16 .

[0037] A magnetic block 14 is provided inside the cleaning wheel 11, which rotates with the cleaning wheel 11. When the magnetic block 14 rotates to the magnetic strip 18, the magnetic block 14 and the magnetic strip 18 repel each other, thereby causing the transmission rod 16 to drop. When the magnetic block 14 rotates away from the magnetic strip 18, the transmission rod 16 will return to its original position under the action of the spring 2 17. Therefore, under the rotation of the cleaning wheel 11, in conjunction with the spring 2 17, the transmission rod 16 continues to reciprocate, and the auxiliary plate 19 fixedly installed at the other end of the transmission rod 16 synchronously follows the reciprocating motion. The auxiliary plate 19 reciprocates at the upper end of the scraper 9, cooperates with the scraper 9 to scrape off the bird droppings, and then separates from the equipment.

[0038] The cleaning mechanism also includes a spraying member arranged between the auxiliary member and the scraping member. The spraying member includes an inner cavity 20 opened inside the transmission plate 6. The inner cavity 20 is slidably connected to a piston plate 21. A transmission column 22 is fixedly installed on the lower end surface of the piston plate 21. A magnetic strip 24 is provided on the upper side of the cleaning wheel 11. The transmission column 22 extends to the lower side of the inner cavity 20 and is fixedly connected to the magnetic strip 24.

[0039] A spring three 23 is fixedly mounted between the piston plate 21 and the inner lower end surface of the inner cavity 20 , and the spring three 23 is sleeved on the outer surface of the transmission column 22 .

[0040] A water inlet pipe 26 is provided between the two groups of transmission plates 6, and a connecting pipe 25 is provided between the water inlet pipe 26 and the inner cavity 20. A connecting cavity 28 is opened inside the scraper 9, and a pipe 27 is provided between the connecting cavity 28 and the inner cavity 20. A spraying pipe 29 is fixedly installed on the inner wall of the scraper 9, and the connecting cavity 28 and the spraying pipe 29 are connected to each other.

[0041] A second spray pipe 30 is provided on the upper side of the auxiliary plate 19 . A second pipe 31 is provided between the second spray pipe 30 and the communication cavity 28 . Multiple groups of spray holes are provided on the outer surfaces of the first spray pipe 29 and the second spray pipe 30 .

[0042] Secondly, the magnetic block 14 inside the cleaning wheel 11 and the magnetic strip 2 24 on the transmission column 22 repel each other. When it rotates to the magnetic strip 24, the piston plate 21 is pushed up by the action of the transmission column 22. When the magnetic strip rotates away from the magnetic strip 24, the piston plate 21 drops back to its original position under the action of the spring 3 23, thereby causing the piston plate 21 to reciprocate. When the piston plate 21 drops, the one-way input method inside the water inlet pipe 26 is opened, and the external water is sucked into the inner cavity 20. When the piston plate 21 rises, it squeezes the water inside the inner cavity 20 and opens the one-way output valve inside the pipe 1 27, discharging the water into the spray pipe 1 29 and the spray pipe 2 30 respectively. The spray pipe 1 29 will spray toward the cleaning wheel 11, and the spray pipe 2 30 will spray toward the scraper 9 and the auxiliary plate 19, thereby improving the cleaning effect of the equipment.

[0043] In the actual application of photovoltaic panels, especially those installed on curved roofs, the cleaning effect is often unsatisfactory. Due to the unique shape and location of such roofs, birds easily roost, resulting in a large amount of bird droppings on the surface of photovoltaic panels. These biological stains have a particularly serious impact on photovoltaic panels because they not only block sunlight and reduce the amount of light received by the panels, but their chemical composition may also react with the surface of the photovoltaic panels, causing permanent damage.

[0044] Traditional cleaning equipment is typically designed to remove general dust and sand. It is less effective against highly adherent and complex contaminants like bird droppings. Failure to effectively remove bird droppings can continuously obstruct light transmittance, significantly reducing the efficiency of photovoltaic panels. Studies have shown that even a thin layer of dust can reduce the efficiency of photovoltaic panels by up to 25%. The obstruction caused by bird droppings is significantly more severe, potentially leading to even greater efficiency losses.

[0045] In addition, long-term accumulation of bird droppings will increase the risk of hot spot effect of photovoltaic panels. When part of the area is blocked, the electricity generated in that area is reduced, but other unblocked areas still work normally. This will cause heat accumulation when the current passes through the blocked area, thereby damaging the battery cells and even causing fire hazards. Therefore, this solution cleans the curved photovoltaic panels by setting up a cleaning mechanism, and especially sets up auxiliary parts for bird droppings to perform double-layer scraping to improve the cleaning effect of bird droppings. At the same time, this solution uses spraying parts to moisten the bird droppings, further enhancing the cleaning effect of the bird droppings.

[0046] Directions:

[0047] When it is necessary to clean the bird droppings and the like on the photovoltaic panels 3, the telescopic rod 4 is started to lower the top block 5, and the lowering of the top block 5 drives the two sets of transmission plates 6 to lower. A spring 17 is provided between the two sets of transmission plates 6, and the scraper 9 at the end of the transmission plate 6 is pressed against the photovoltaic panels 3 under the action of the spring 17. As the top block 5 continues to descend, the scraper 9 at the end of the transmission plate 6 will keep pressing against the photovoltaic panels 3 and continue to advance, thereby cleaning the garbage thereon. At the same time, the internal rotation of the scraper 9 is connected to the rotating shaft 10, and the gear 12 on the rotating shaft 10 is engaged with the rack 13. Therefore, the rotating shaft 10 will rotate when following the displacement of the scraper 9, and carry the cleaning wheel 11 to rotate for cleaning.

[0048] A magnetic block 14 is provided inside the cleaning wheel 11 and rotates along with the cleaning wheel 11. When the magnetic block 14 rotates to the magnetic strip 18, the magnetic block 14 and the magnetic strip 18 repel each other, thereby causing the transmission rod 16 to descend. When the magnetic block 14 rotates away from the magnetic strip 18, the transmission rod 16 returns to its original position under the action of the spring 2 17. Therefore, under the rotation of the cleaning wheel 11, in conjunction with the spring 2 17, the transmission rod 16 continues to reciprocate, and the auxiliary plate 19 fixedly mounted at the other end of the transmission rod 16 synchronously follows the reciprocating motion. The auxiliary plate 19 reciprocates on the upper end of the scraper 9, cooperates with the scraper 9 to scrape the bird droppings and then separates from the equipment.

[0049] Secondly, the magnetic block 14 inside the cleaning wheel 11 and the magnetic strip 2 24 on the transmission column 22 repel each other. When it rotates to the magnetic strip 24, the piston plate 21 is pushed up by the action of the transmission column 22. When the magnetic strip rotates away from the magnetic strip 24, the piston plate 21 drops back to its original position under the action of the spring 3 23, thereby causing the piston plate 21 to reciprocate. When the piston plate 21 drops, the one-way input method inside the water inlet pipe 26 is opened, and the external water is sucked into the inner cavity 20. When the piston plate 21 rises, it squeezes the water inside the inner cavity 20 and opens the one-way output valve inside the pipe 1 27, discharging the water into the spray pipe 1 29 and the spray pipe 2 30 respectively. The spray pipe 1 29 will spray toward the cleaning wheel 11, and the spray pipe 2 30 will spray toward the scraper 9 and the auxiliary plate 19, thereby improving the cleaning effect of the equipment.
