[0029] The working principle of the present utility model is as follows: When the photovoltaic panel cleaning robot moves along the top of the photovoltaic panel, starting the drive motor 3 to work can drive the rotation of the rotating shaft 15 and the first bevel gear 16. The rotation of the first bevel gear 16 can drive the second bevel gear 21 and the rotating rod 20 to rotate along the bearing on the fixed box 2. The rotation of the rotating rod 20 can drive the rotation of two groups of brush roller shafts 12. Under the action of rotation, the brush roller shafts 12 can sweep the dust on the surfaces of the two lower rows of photovoltaic panels, thus achieving the effect of cleaning the surfaces of the photovoltaic panels. And when it is necessary to disassemble and replace the brush roller shafts 12, pulling the pin rod 25 downward can compress the support spring 22 on the support block 24 until the pin rod 25 can be disengaged from the surface of the pin hole 23, and the limitation of the limit baffle 9 can be released. Subsequently, by pulling the limit baffle 9 and the limit disc 11 to move until the limit disc 11 can be disengaged from the surface of the brush roller shaft 12, the personnel can remove the brush roller shaft 12 from the surface of the rotating rod 20, thus achieving the effect of quickly disassembling the brush roller shaft 12. The overall operation is convenient and fast, bringing great convenience to the maintenance and replacement work of the personnel.
