[0034] In one embodiment, the first cleaning part 1 includes a first housing 12, a first partition 13 and a first roller brush 11, the first housing 12 is provided with a driving assembly 3, the first partition 13 is slidably connected to the screw rod 4, one end of the first roller brush 11 is rotatably connected to the first housing 12, and the other end of the first roller brush 11 is connected to the first partition 13.

During the cleaning process, the two rotating wheels 51 are in contact with the upper end surface of the photovoltaic panel 10 along the first direction X. When the first cleaning part 1 and the second cleaning part 2 move along the second direction Y, the rotating wheels 51 can also follow them to move along the second direction Y on the upper end surface of the photovoltaic panel 10, so that the end of the first cleaning part 1 is always flush with the upper end surface of the photovoltaic panel 10, ensuring the smooth progress of the entire cleaning process.

[0043] Specifically, see Figures 1 to 3 The specific use process of the photovoltaic panel cleaning machine provided in this embodiment is as follows:

[0044] First, the suspension wheel frame 5 is suspended on the upper end of the photovoltaic panel 10 along the first direction X so that the circumference of the rotating wheel 51 contacts the upper end surface of the photovoltaic panel 10. Then, the laser distance measuring component 8 is started, and the laser distance measuring component 8 emits a distance measuring laser. The length L of the photovoltaic panel in the first direction X can be calculated by the following formula: L=S-D, where S is the distance between the laser emitting end of the laser distance measuring component 8 and the contact point between the rotating wheel 51 and the upper end surface of the first direction X. The value of S is a constant and can be measured when the laser distance measuring component 8 is installed. D is the distance between the laser emitting end of the laser distance measuring component 8 and the lower end surface of the photovoltaic panel 10 along the first direction X measured by the installation of the laser distance measuring component 8. After the L value is calculated, the L value is fed back to the controller, and the controller controls the driving component 3 to start, and the driving component 3 drives the screw 4 to rotate, so that the first cleaning part 1 and the second cleaning part 2 are relatively extended by a preset length, which is equal to the length L, so that the first roller brush 11 and the second roller brush 21 can cover the length of the photovoltaic panel 10 in the first direction X.

[0045] After the first roller brush 11 and the second roller brush 21 cover the length of the photovoltaic panel 10 in the first direction X, the first drive motor 112 and the second drive motor 212 are started, the first drive motor 112 drives the first cleaning roller 111 to rotate, and the second drive motor 212 drives the second cleaning roller 211 to rotate, the first cleaning roller 111 and the second cleaning roller 211 clean the surface of the photovoltaic panel 10, and at the same time, the moving component 6 is started, and the moving component 6 drives the first cleaning part 1 and the second cleaning part 2 to move along the second direction Y, thereby cleaning the entire surface of the photovoltaic panel 10. The entire cleaning process does not require the use of water, and the waterless cleaning method is adopted, which can effectively save water resources.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
