[0024] During specific use, the driving mechanism is provided to drive the rotating rod 14 to rotate less than 180°, and the rotating rod 14 drives the photovoltaic panel 16 on the storage plate 15 to flip synchronously, so that the photovoltaic panel 16 is distributed in a horizontal state when receiving sunlight, and is distributed in a vertical state when the surface of the photovoltaic panel 16 is cleaned. When the photovoltaic panel 16 is in a vertical state, the electric slide rail 17 is provided to drive the horizontal plate 19 on the slider 18 to move vertically up and down, so that the cleaning brush 191 cleans the surface of the photovoltaic panel 16, and the dust and dirt generated during the cleaning process of the cleaning brush 191 will fall vertically downward due to gravity, so that the dust and dirt falls into the dust collecting frame 23 for collection.

[0025] It should be noted that the dust collecting frame 23 is rotatably connected to the cross bar 21 via the mounting plate 22, so that no matter how the storage plate 15 rotates, the feed port of the dust collecting frame 23 is always arranged vertically upward.

[0026] As an implementation method in this embodiment, Figure 4 As shown, the driving mechanism includes a driven gear 30 fixedly sleeved on the outer wall of the rotating rod 14 and a driving motor 31 fixed on the side wall of the load block 13. A rotating shaft 32 is welded and fixed on the output shaft of the driving motor 31. A driving gear 33 is fixedly sleeved on the outer wall of one end of the rotating shaft 32. The driving gear 33 is meshingly connected with the driven gear 30.

[0027] During specific use, the driving motor 31 is provided to drive the rotating shaft 32 to rotate, so that the driving gear 33 on the rotating shaft 32 drives the gear to rotate synchronously, so that the rotating shaft 32 and the rotating rod 14 move synchronously, thereby driving the storage plate 15 on the rotating rod 14 to rotate less than 180°.

[0028] As an implementation method in this embodiment, Figure 1 As shown, a sunshade 40 for protecting the driving mechanism is fixedly installed on the upper end surface of the load block 13 by bolts, and the sunshade 40 is located above the driving mechanism. The sunshade 40 is provided to shade the driving motor 31, so as to prevent the driving motor 31 from being damaged by excessive heat caused by direct sunlight on the driving motor 31, and the sunshade 40 can block falling objects from high altitude, thus playing a certain protective role for the driving mechanism.

[0029] As an implementation method in this embodiment, Figure 1 As shown, a protective frame 41 for placing a cleaning brush 191 is fixedly installed on the side wall of the storage plate 15 by bolts.

[0031] During specific use, the power input end of the control switch 51 is electrically connected to the power output end of the battery 50, and the power input ends of the drive motor 31 and the electric slide rail 17 are electrically connected to the power output end of the control switch 51. The opening and closing of the drive motor 31 and the electric slide rail 17 are controlled by the set control switch 51, and the drive motor 31 is a servo motor, which can accurately control the rotation angle of the rotating shaft 32.

[0032] In this embodiment, the rotating rod 14 and the storage plate 15 are an integrally formed structure, and the storage plate 15 is an L-shaped structure. Too many things are installed on the storage plate 15, so the storage plate 15 has a large load-bearing capacity, so the connection between the storage plate 15 and the rotating rod 14 must be very stable.

[0033] Working principle: During use, the drive motor 31 is provided to drive the rotating shaft 32 to rotate, so that the active gear 33 on the rotating shaft 32 drives the gear to rotate synchronously, so that the rotating shaft 32 and the rotating rod 14 move synchronously, thereby driving the storage plate 15 on the rotating rod 14 to rotate less than 180°, and the rotating rod 14 drives the photovoltaic panel 16 on the storage plate 15 to flip synchronously, so that the photovoltaic panel 16 is distributed in a horizontal state when receiving sunlight, and is distributed in a vertical state when cleaning the surface of the photovoltaic panel 16. When the photovoltaic panel 16 is in a vertical state, the electric slide rail 17 is provided to drive the horizontal plate 19 on the slider 18 to move vertically up and down, so that the cleaning brush 191 cleans the surface of the photovoltaic panel 16, and the dust and dirt generated during the cleaning process of the cleaning brush 191 will fall vertically downward due to gravity, so that the dust and dirt falls into the dust collecting frame 23 for collection.
