[0038] The present invention provides a method to solve the problem that dust and dirt will stick to the roller brush, which will clog the roller brush and reduce the cleaning effect. At the same time, during the cleaning process, dust and dirt will be scattered to the surrounding environment or photovoltaic modules, making it impossible to keep the working area clean, causing secondary pollution during the cleaning process.

[0040] It should be noted that a second square cavity 9 is provided on both sides of the box body 1, and a first transmission wheel 55, a first transmission belt 56 and a second transmission wheel 57 are arranged inside the second square cavity 9. A rotating shaft 52 is rotatably arranged on the top of the second square cavity 9, and the middle periphery of the rotating shaft 52 is fixedly connected to the inner wall of the worm gear 53, and the first transmission wheels 55 are fixedly connected at both ends of the rotating shaft 52. A rotating rod 58 is fixedly connected at both ends of the brush roller 12, and the rotating rod 58 passes through the side wall of the second square cavity 9 and is fixedly connected to the second transmission wheel 57. The first transmission wheel 55 and the second transmission wheel 57 are both connected to the first transmission belt 56 for transmission; when the first transmission wheel 55 rotates, the first transmission wheel 55 drives the second transmission wheel 57 to rotate through the first transmission belt 56, and the second transmission wheel 57 rotates to drive the rotating rod 58 to rotate, so that the brush roller 12 cleans the photovoltaic module.

[0041] In the present invention, a linkage assembly 6 is arranged inside the second square cavity 9, and the linkage assembly 6 includes a third transmission wheel 61, a second transmission belt 62 and a fourth transmission wheel 63. The third transmission wheel 61 is fixedly connected to the end of the rotating shaft 52, and the fourth transmission wheel 63 and the third transmission wheel 61 are both transmission-connected to the second transmission belt 62; when the rotating shaft 52 rotates, the third transmission wheel 61 is driven to rotate, and the third transmission wheel 61 drives the fourth transmission wheel 63 to rotate through the second transmission belt 62, and the fourth transmission wheel 63 rotates to rotate the reciprocating screw rod 64.

[0043] In the present invention, the bristles of the brush roller 12 are in active contact with the receiving plate 31 and the toothed scraper 21 respectively; when cleaning the surface of the photovoltaic module, the box body 1 is placed on the surface of the photovoltaic module, and the brush roller 12 is rotated to quickly clean the surface of the photovoltaic module. During the cleaning process, the brush roller 12 will be contaminated with dust and dirt. The rotation direction of the brush roller 12 is clockwise. After the bristles of the brush roller 12 rotate to the position of the toothed scraper 21, the sharp toothed edge of the toothed scraper 21 can penetrate into the tiny gaps and uneven surfaces that are difficult for the brush roller 12 to reach, so that the toothed scraper 21 can scrape off the stubborn dirt and residue attached to the brush roller 12, thereby ensuring the cleaning effect and more thorough cleaning.

[0044] It should be noted that, when the brush roller 12 is cleaning the photovoltaic module, the toothed scraper rod 21 can remove the dust and dirt thereon, so that the brush roller 12 is always kept clean, preventing the accumulation of excessive dust and dirt on the brush roller 12 and causing blockage, thereby improving the cleaning effect of the brush roller 12.

[0045] In the present invention, a collecting box 3 is inserted into the collecting groove 13, and a receiving plate 31 is fixedly connected to the end of the collecting box 3. The receiving plate 31 is an arc plate, and the receiving plate 31 is higher near the end of the brush roller 12. Since the fixed plate 2 and the toothed scraper rod 21 are arranged at an angle, during the cleaning process of the brush roller 12, the fixed plate 2, the toothed scraper rod 21 and the receiving plate 31 below cooperate to make dust and dirt flow smoothly downward into the collecting box 3, effectively collecting dust and dirt, ensuring that the dust and dirt will not fly into the surrounding environment or fall on the photovoltaic modules after being scraped off, thereby keeping the working area clean, preventing secondary pollution during the cleaning process, and avoiding repetitive work of the staff.

[0046] Furthermore, the arc-shaped setting of the receiving plate 31 can ensure that the falling dust falls into the collecting box 3 along the receiving plate 31, thereby improving the collection effect of dust and dirt.

[0047] In the present invention, a filter screen 41 is fixedly connected to the top surface of the collection trough 13, a cleaning brush 71 is slidably provided on the bottom surface of the filter screen 41, and a vacuum cleaner 4 is provided on the top of the box body 1 close to the collection box 3, and the vacuum cleaner 4 is located above the filter screen 41; the vacuum cleaner 4 can quickly suck in the dust and dirt scraped off by the fixed plate 2 and the toothed scraper rod 21 to prevent them from falling back into the photovoltaic module or the surrounding environment, thereby reducing the dust phenomenon during operation, improving the air quality of the working environment, and significantly improving the cleaning efficiency.

[0048] Furthermore, the filter 41 helps filter dust and dirt, preventing dust from being released back into the air through the exhaust port, thereby maintaining the cleanliness of the air. During the cleaning process, the cleaning brush 71 also cleans the surface of the filter 41, thereby effectively removing attached large particles of pollutants such as dust and hair, and preventing these impurities from clogging the small holes of the filter 41, thereby keeping the filter 41 unobstructed.

[0049] Furthermore, while the cleaning brush 71 cleans the filter 41, it also helps optimize the cleaning efficiency of the vacuum cleaner 4. Due to the cleaning effect of the cleaning brush 71, the cleaning frequency of the filter 41 can be reduced accordingly, thereby reducing the user's maintenance cost.

[0051] It should also be noted that the side wall of the box body 1 is equipped with a card connector for receiving the card collection box 3, which is a mature technology in the prior art and will not be described in detail here.

[0052] The receiving plate 31 and the toothed scraper rod 21 are both located inside the cleaning tank 11 , so as to better scrape and collect the dust and dirt on the brush roller 12 .
