The bottom of the fixing box 230 is connected to the fixing block 240 through the support component 400.

[0033] A water pump 340 is fixedly connected to the inner side of the housing 310 by bolts. The output end of the water pump 340 is connected to the spray plate 150. The spray plate is evenly distributed with nozzles facing the photovoltaic panel. The motor 160 and the water pump 340 are electrically connected to independent switches.

[0034] The support components 400 are located at the bottom of the first fixing plate 110 and the second fixing plate 140.

[0035] The bottom of the fixing block 410 is coaxially connected to a fixing seat 420. A round rod 430 is tightly welded to the bottom of the fixing seat 420. A support column 440 is inserted into the bottom of the round rod 430. A tightening bolt is provided on the side end of the support column and makes movable contact with the round rod inside, so as to facilitate the adjustment of the height of the round rod.

[0036] Meanwhile, in order to ensure that the scraper 124 cleans more thoroughly, the scraper component 120 includes a fixed rod 121. Sliding blocks 122 and 123 are tightly welded to both sides of the fixed rod 121. The scraper 124 is fixed to the side of the fixed rod 121 by a fixed plate 125. The scraper can be made of rubber and its lower end is in contact with the surface of the photovoltaic panel.

[0037] Furthermore, for better support, the support assembly 400 specifically includes a second fixing block 410 connected to the first fixing plate 110 and the second fixing plate 140. The bottom of the second fixing block 410 is coaxially connected to a fixing seat 420.

[0046] Working Principle: When this device is in operation, the cleaning component 100 drives the scraper component 120 to slide smoothly along the guide rail 130 via the motor 160. The scraper 124 closely adheres to the surface of the photovoltaic panel 210, effectively removing accumulated dust and dirt, ensuring the high-efficiency power generation of the photovoltaic panel 210. Simultaneously, the nozzle 150 on the fixing plate 140 sprays clean water or cleaning agent as needed to enhance the cleaning effect. The sliding blocks 122 and 123 of the scraper component 120 move smoothly on the guide rail 130, thanks to the stable support of the fixing rod 121 and the fixing plate 125. The fixing block 410 of the support component 400 is tightly connected to the pin inside the fixing base 420 through holes on its side, forming a stable support structure. The round rod 430 can be adjusted in height, facilitating the adjustment of the mating positions between various components and greatly improving the adaptability of the device. The mounting bracket 220 firmly secures the photovoltaic panel 210, while the mounting box 230 integrates the storage space for key electronic components such as the controller 231, battery 232, and inverter 233. In addition, the groove design inside the mounting box 230 and mounting block 240 not only provides a precise installation position for the support component 400, but also effectively prevents loosening or damage caused by vibration or external impact through a tight fit, simplifying the installation and maintenance process and reducing operation and maintenance costs, all of which provide a solid guarantee for the long-term operation of the photovoltaic power station.
