[0051] Specifically, the rotation of the second screw rod 32 can drive the toggle block 45 to move, so that the toggle block 45 can drive the bending frame 49 to move, so that the bending frame 49 can drive the blocking block 50 to move downward, triggering the blocking block 50 to open, so that the water in the water tank 46 flows into the inner side of the water storage shell 39 through the expansion 52 and the water pipe 53, and then flows into the inner side of the cleaning brush 40 through the water storage shell 39. When the toggle block 45 is separated from the bending frame 49, the fifth spring 48 uses elastic force to support the bending frame 49 to reset under the support of the bottom plate 47, so that the blocking block 50 closes the water outlet, so that the cleaning brush 40 uses water to improve the photovoltaic The cleaning work of the panel body 28 surface is that when the second gear 38 moves to contact the tooth block 64, the tooth block 64 moves into the inner side of the support block 62 under the pressure of external force, and when the second gear 38 is reset, the second gear 38 is driven to rotate under the meshing action of the tooth block 64, so that the second gear 38 can drive the water storage shell 39 to flip, so that the third clamping block 44 is three-phase clamped with the circular hole under the elastic force support of the fourth spring 43, so as to fix the second gear 38, and the rubber scraper 41 is made to contact the surface of the photovoltaic panel by flipping, and the water remaining on the surface of the photovoltaic panel is cleaned, and the photovoltaic panel body 28 is cleaned for the second time;

[0052] When the water storage shell 39 moves to the support block 62 at the other end of the movable frame 24 , the tooth block 64 is used to flip and reset the water storage shell 39 , so that the cleaning brush 40 contacts the surface of the photovoltaic panel body 28 again.

[0053] Working principle: By moving the side frame 1 to the position where the photovoltaic panel body 28 is installed, the staff controls the external handling device to carry the photovoltaic panel body 28 onto the two movable frames 24. Then, the threaded blocks 26 are rotated in sequence, and the extrusion bolts 27 are screwed to make multiple extrusion bolts 27 move downward under the threaded support of the threaded blocks 26 to extrude and fix the photovoltaic panel body 28. Next, the movable frames 24 are moved to the inside of the frame 23, and the first driving motor 9 is controlled to operate, so that the output end of the first driving motor 9 drives the first lead screw 10 to rotate, and the mounting frame 11 drives the EL detection device to move to a suitable position under the threaded support of the first lead screw 10. According to the angle required for installation, the second driving motor 16 is controlled to operate, so that the output end of the second driving motor 16 drives the first gear 171 to rotate through the first shaft block 17. The first gear 171 drives the toothed plate 18 to move through meshing, and the toothed plate 18 drives the frame 23 to move through the first connecting frame 22 under the action of an external force, so that the frame 23 drives the photovoltaic panel body 28 to tilt through the movable frame 24. At the same time, the EL detection device installed on the mounting frame 11 tilts together with the photovoltaic panel body 28. Before the EL detection of the photovoltaic panel body 28, by controlling the operation of the second driving motor 16, the cleaning brush 40 can clean the surface of the photovoltaic panel body 28. When the cleaning brush 40 sweeps the dust on the surface of the photovoltaic panel body 28 to the position of the air pipe 61, the external air pump is controlled to operate, so that the external air pump moves the gas through the pipeline to the air pipe 61, and then the air pipe 61 sprays the gas to blow off the dust swept to one side of the photovoltaic panel body 28. The operation of the second driving motor 16 triggers the block 50 to open, so that the water in the water tank 46 flows into the inside of the water storage shell 39 through the flared opening 52 and the water pipe 53, and then flows into the inside of the cleaning brush 40 through the water storage shell 39, so that the cleaning brush 40 uses the water to improve the cleaning work on the surface of the photovoltaic panel body 28. When the cleaning is reset, the rubber scraper 41 contacts the surface of the photovoltaic panel by flipping to clean the residual water on the surface of the photovoltaic panel. The EL detection device is controlled to detect the photovoltaic panel body 28.
