[0069] Photovoltaic power station operation and maintenance is a key link to ensure the safe and stable operation of photovoltaic power stations and improve power generation efficiency and economic benefits.

[0070] In related technologies, when photovoltaic power station operation and maintenance equipment is in operation, the flat plate of the equipment is parallel to the inclined surface of the photovoltaic panel, and the cleaning roller abuts the surface of the photovoltaic panel and then moves from left to right, allowing the cleaning roller to clean the surface of the photovoltaic panel. The exhaust fan is activated, and the dust suction pipe sucks away the dust on the surface of the photovoltaic panel and stores it in the dust storage box. The booster pump is activated, and the water in the water tank is sprayed out through the water nozzle to rinse the photovoltaic panel after the dust is sucked. At the same time, the cleaning roller can further clean the photovoltaic panel after rinsing.

[0071] However, the cleaning roller can become contaminated during the cleaning process. The contaminated roller continues to clean the photovoltaic panels, leaving traces of mud on the surfaces of the panels. Therefore, the present application provides a photovoltaic power station operation and maintenance device to address or improve the problem of residual mud on the surfaces of photovoltaic panels after cleaning with a cleaning roller.

[0072] The following combination Figures 1 to 10, describing the embodiments of the present application.

[0077] In this embodiment, if Figure 1 、 Figure 3 and Figure 6 As shown, the first through hole 1011 is arranged corresponding to the photovoltaic panel, the cleaning roller 104 is rotatably connected to the inner wall of the first shell 101, the first driving mechanism 105 drives the cleaning roller 104 to rotate, and part of the cleaning roller 104 extends out of the first through hole 1011. The part extending out of the first through hole 1011 is suitable for cleaning the surface of the photovoltaic panel, and the first scraper 1012 extends inward from the edge of the first through hole 1011. The end of the first scraper 1012 away from the first shell 101 slides and abuts against the cleaning roller 104, which can scrape off the stains on the cleaning roller 104, and the stains flow along the first scraper 1012 to the first sewage tank 1013. After the cleaning roller 104 is cleaned by the first scraper 1012, the photovoltaic panel is cleaned, which can prevent mud marks from remaining on the surface of the photovoltaic panel.

[0078] In some embodiments, as Figure 10 As shown, the first driving mechanism 105 is a motor, which is fixed to the outer wall of the first shell 101. The first shell 101 is provided with a first hole corresponding to the output shaft of the first driving mechanism 105.

The first side is rotatably connected to the inner wall of the first shell 101, and the second side is arranged toward the first sewage tank 1013. There is a first gap between the cleaning roller 104 and the inner top wall of the first shell 101, and the first baffle 107 is suitable for blocking the first gap.

[0085] In this embodiment, if Figure 6 As shown, the first spraying part 1061 of the first spraying mechanism 106 sprays the surface of the cleaning roller 104, and the sewage formed after spraying is scraped by the first inclined section 10122, and the sewage is introduced into the first sewage tank 1013, so as to further clean the cleaning roller 104, so that the cleaning roller 104 remains clean when in contact with the photovoltaic panel; the first baffle 107 blocks the first gap, and the first baffle 107, the cleaning roller 104, the first scraper 1012 and the inner wall of the first shell 101 form a cleaning space to prevent the sewage generated by cleaning from splashing through the first gap to the part of the cleaning roller 104 away from the cleaning space; the first side edge of the first baffle 107 is rotatably connected to the inner wall of the first shell 101, so that the first baffle 107 can move, thereby preventing the cleaning roller 104 from generating stress at the connection between the first baffle 107 and the inner wall of the first shell 101 when the cleaning roller 104 rotates.

[0086] In some embodiments, as Figure 2 and Figure 6As shown, the first spraying mechanism 106 includes a water tank 1063, a water pipe 1062 and a nozzle.

After the drying roller 109 is dried by the second scraper 1082 and the squeezing assembly 110, it wipes the photovoltaic panel, which can further prevent mud marks from remaining on the surface of the photovoltaic panel.
