The working principle of the application is as follows:
in the daytime, the first photovoltaic module 21 and the second photovoltaic module 22 generate electricity by using solar energy, and the first photovoltaic module 21 and the second photovoltaic module 22 are at an angle of 180 degrees, as shown in fig. 1. At this time, one end of the first driving rod 1117a facing the outside of the air duct 111 protrudes out of the surface of the air duct 111, as shown in fig. 5. The drive gear 1412 and driven gear 1116c are disengaged, see fig. 4.
At night, the motor 141 is operated, the output shaft 1411 drives the driving gear 1411c to rotate, the driving gear 1411c drives the second rack 134 to move, and the auxiliary page 13 rotates 180 degrees and is abutted to the main page 11 under the action of the second rack 134, which is shown in fig. 6. In this process, the second rectangular frame presses the first driving rod 1117a, and the driven gear 1116c is moved toward the driving gear 1412 and engaged with the driving gear 1412, as shown in fig. 7, 8 and 9. The motor 141 continues to run and the output shaft 1411 continues to rotate. At this time, the output shaft 1411 and the drive gear 1411c rotate relative to each other, and the drive gear 1411c cannot rotate any further, i.e., the output shaft 1411 rotates against the damping between the output shaft 1411 and the drive gear 1411 c. The output shaft 1411 drives the driving gear 1412 and the driven gear 1116c to rotate, the driven gear 1116c drives the screw 1116 to rotate, and the sliding seat 1115 moves along the air duct 111 under the action of the screw 1116. Slide holder 1115 moves shaft 114 from one end of slot 1112 to the other end of slot 1112. Meanwhile, when the sliding seat 1115 moves, under the action of the first rack 142, the first gear 1115b and the second gear 1115c rotate, the second gear 1115c drives the rotating shaft 114 to rotate, and the rotating shaft 114 drives the brush 1141 to rotate, so that the cleaning capability of the brush 1141 on the first photovoltaic module 21 and the second photovoltaic module 22 is improved. See fig. 10 and 11. In the process, when the blades in the air pipes with the filter screens rotate, the air outside the air pipes is guided into the air pipes, and when the blades in the other air pipes rotate, the air in the air pipes is guided out from the pipe openings. Specifically, the blades 12 rotate, air enters one of the air ducts 111 through the screen 1114, the air enters the first space 101 through the slot 1112 and passes between the first photovoltaic module 21 and the second photovoltaic module 22, and then the air enters the other air duct 111 through the slot 1112 and exits from the nozzle 1113. In this process, the air carries away dust on the first photovoltaic module 21, the second photovoltaic module 22, and the brush 1141. When the rotation shaft 114 moves to the other end of the long hole 1112, the motor 141 stops operating. At this time, the sub-page 13 and the main page 11 maintain the abutting state, thereby reducing the accumulation of dust in the air at night on the first photovoltaic module 21 and the second photovoltaic module 22.
When the daytime comes, the motor 141 is operated in reverse. The output shaft 1411 rotates to drive the driving gear 1411c to rotate, and the auxiliary sheet 13 rotates 180 degrees under the action of the second rack 134 until the included angle between the first photovoltaic module 21 and the second photovoltaic module 22 is 180 degrees. In the process, the driven gear 1116c and the driving gear 1412 are disengaged by the elastic body 1118a, and the first driving rod 1117a protrudes out of the surface of the duct 111 again toward the end outside the duct 111.
