[0020] The preferred technical solution is that the liquid spraying mechanism includes a detergent box 6 installed on one side of the upper surface of the mobile frame 1, and the detergent box 6 contains detergent, which is arranged at the front end of the moving direction of the mobile frame 1, and the lower surface of the detergent box 6 is evenly provided with a plurality of nozzles 7 along the axial direction of the roller brush 5, and the nozzle 7 is provided with a solenoid valve 8. The solenoid valve 8 is powered by an external power supply or a rechargeable battery carried on the mobile frame 1, and a corresponding control switch is provided on the mobile frame 1. Before the solar panel is brushed by the roller brush 5, the solenoid valve 8 is opened first, so that the detergent in the detergent box 6 is sprayed on the surface of the solar panel through the nozzle 7, and then brushed by the roller brush 5, thereby improving the cleaning effect.

[0021] A further preferred technical solution is that a cleaning water tank 11 with the same structure as the detergent tank 6 is provided on the other side of the upper surface of the mobile frame 1, and a plurality of nozzles 7 are evenly provided on the lower surface of the cleaning water tank 11 along the axial direction of the roller brush 5. The nozzle 7 is provided with a solenoid valve 8, which is also powered by an external power supply or a rechargeable battery carried by the mobile frame 1, and a corresponding control switch is also provided on the mobile frame 1. The cleaning water tank 11 is arranged at the rear end of the moving direction of the mobile frame 1. After the roller brush 5 brushes the surface of the solar panel, the clean water in the cleaning water tank 11 is sprayed onto the solar panel through the nozzle 7 to rinse the detergent remaining on its surface, so as to avoid the residual detergent from affecting the power generation function of the solar panel.
