In this embodiment, the first hydraulic rod 13 plays a role in promoting the telescopic movement of the brush plate 27. When the brush plate 27 is in the working state, it extends outward beyond the position of the water distribution tray 33. That is, when the push-plate cart 1 is moving, when the brush plate 27 is close to the photovoltaic panel, it is not affected by the water distribution tray 33.

[0026] like Figure 2 and Figure 3 As shown, the cleaning component 2 includes a protective shell 21 fixed to the outer end of the rotating arm 14, and a second hydraulic rod 26 is hinged on the upper side of the protective shell 21, and the piston rod end of the second hydraulic rod 26 is rotatably connected to the brush plate 27, the motor 22 is installed on the inner side of the protective shell 21, and the output shaft of the motor 22 is connected to the rotating shaft 24 through the first coupling 23, and the outer end of the rotating shaft 24 is connected to the brush plate 27 through the second coupling 25, and an annular groove 273 is provided on the back side of the brush plate 27, and the inner and outer groove walls of the annular groove 273 are both provided with a limiting groove 274, a slider 271 is slidably connected inside the annular groove 273, and the outer wall of the slider 271 is connected to the limiting block 272, and the limiting block 272 is slidably connected in the limiting groove 274.

[0029] When in use, first use the lifting frame, lifting arm and rotating arm to move the cleaning device to the light-receiving surface of the photovoltaic panel, then start the second hydraulic rod to drive the brush plate to rotate to an appropriate angle so that it fits the surface angle of the photovoltaic panel, and then start the motor to drive the brush plate to rotate through the coupling and the drive shaft, so that it rotates and rubs on the light-receiving surface of the photovoltaic panel. During the cleaning process, the brush plate is retracted by the rotating arm of the first hydraulic rod, and the brush surface of the brush plate is flipped downward by the second hydraulic rod. Then, the height of the brush plate is adjusted again by the lifting frame so that its bristles are in contact with the vertical rod, that is, the vertical rod is inserted into the bristles, and then the water pump and the motor are started.
