When encountering bad weather, the dual-axis motor 22 drives the mounting frame 21 to rotate counterclockwise to a horizontal state, so that the back of the photovoltaic panel 211 faces upward, and then starts The cylinder 233 drives the push plate 232 to slide downward, the push plate 232 drives the lifting cylinder 23 to move downward, the lifting cylinder 23 drives the fourth gear 231 to move downward, the top fourth gear 231 is separated from the first gear 213, and the bottom fourth gear 231 is meshed with the fifth gear 313, so the second rotating rod 223 rotates to drive the lifting cylinder 23 to rotate, the lifting cylinder 23 drives the bottom fourth gear 231 to rotate, the bottom fourth gear 231 drives the fifth gear 313 to rotate, the fifth gear 313 drives the second screw rod 312 to rotate, the second screw rod 312 drives the connecting block 311 to move upward, the connecting block 311 drives the protective cover 31 to move upward, and finally contacts the front side of the photovoltaic panel 211, so as to shield and protect the surface of the photovoltaic panel 211 after it is turned 180 degrees, so as to avoid rain. The surface is polluted and damaged in bad weather such as snow, and the connection block 311 moves to drive the clamping rod 314 to rise.

When the protective cover 31 is fully raised After that, the second cleaning plate 321 is located at the outermost side of the protective cover 31, and the push-pull plate 323 is in a horizontal state, so the second cleaning plate 321 cleans the dust on the protective cover 31 to avoid dust or garbage from polluting the photovoltaic panel 211 when it rises to protect the photovoltaic panel 211. During the operation of the photovoltaic panel 211, the driving machine 216 is started to drive the threaded rod 215 to rotate, and the threaded rod 215 drives the slider 217 to slide along the track of the slide groove 214. The slider 217 mobilizes the first cleaning plate 218 to slide, which can clean the surface of the photovoltaic panel 211 to avoid dust accumulation on the surface due to long-term working, resulting in reduced power generation efficiency.
