[0021] The first electric push rod 8 is used to pull the rack 10 to move, and the rack 10 is engaged with the gear 6 to pull the gear 6 to rotate, so that the gear 6 drives the rotating rod 3 and the rotating drum 4 to rotate. In this way, the photovoltaic panel 5 on the rotating drum 4 can be turned over at night, so that the photovoltaic panel 5 is flipped into the inside of the fixed drum 1 to reduce the probability of impurities and bird droppings falling on the photovoltaic panel 5, which can help the photovoltaic panel 5 to improve the power generation efficiency to a certain extent.

[0022] Among them, the orientation adjustment component includes a support plate 11, a U-shaped seat 12 is fixed on the upper surface of the support plate 11, a first carrier tube 13 is rotatably connected between the relative inner walls of the U-shaped seat 12 through a pin shaft, a connecting block 14 is fixed to the outer wall of the first carrier tube 13, the connecting block 14 is fixedly installed on the outside of the fixed cylinder 1, a U-shaped block 15 is fixed on the fixed cylinder 1 and the support plate 11, a second carrier tube 16 is rotatably connected between the relative inner walls of the U-shaped block 15 through a pin shaft, and a second electric push rod 17 is arranged between the two second carrier tubes 16.

[0023] The second electric push rod 17 can be used to push the fixing tube 1 to pull the photovoltaic panel 5 to rotate around the first carrier tube 13 to adjust the inclination angle of the photovoltaic panel 5 in the longitudinal direction.

[0024] Among them, a pillar 18 is arranged through the middle of the support plate 11, and the joint of the support plate 11 and the pillar 18 is rotatably connected through a bearing.
