[0026] The working principle of the present invention is as follows: when in use, the collection tank 20 collects rainwater through the liquid collection port 27, and at the same time filters impurities in the rainwater through the filter holes 29 on the partition 30. When it is necessary to clean the dust on the surface of the lower photovoltaic panel 4 and the upper photovoltaic panel 5, the drive motor 2 is started to rotate forward and reverse, and the drive motor 2 will drive the threaded rod 1 to rotate forward and reverse. The threaded rod 1 is engaged with the threaded sleeve 23 to make the threaded sleeve 23 reciprocate.

The cleaning process does not require manual cleaning, which reduces the workload and the danger. The brush plate 18 will drive the baffle plate 19 to move during the movement, and the baffle plate 19 will drive the rubber plug 24 to move, so that the drain pipe 28 is separated from the socket 25 and the rubber plug 24 is separated from the drain pipe 28. At this time, the water in the collection tank 20 will flow out through the drain pipe 28 and flow into the lower photovoltaic panel 4 and the upper photovoltaic panel 5, so that the brush 17 can better clean the dust on the surface of the photovoltaic panel, thereby improving the cleaning effect of the dust on the photovoltaic panel. When the lower photovoltaic panel 4 and the upper photovoltaic panel 5 are used, the upper electric push rod 9 and the lower electric push rod 13 are started to extend, and the upper electric push rod 9 and the lower electric push rod 13 are started to extend. When the upper support frame 2 8 and the lower support frame 1 14 are rotated, the upper electric push rod 9 will rotate with the upper support frame 2 8 and the mounting seat, and the lower electric push rod 13 will rotate with the lower support frame 1 14 and the mounting seat. When the upper support frame 2 8 rotates, it will push the upper rotating frame 6 to rotate through the upper support frame 1 7. At the same time, the upper support frame 1 7 will rotate with the upper rotating frame 6 and the upper support frame 2 8. When the lower support frame 1 14 rotates, it will push the lower rotating frame 3 to rotate through the lower support frame 2 15. The lower support frame 2 15 will rotate with the lower rotating frame 3 and the lower support frame 1 14, thereby changing the angles of the lower photovoltaic panel 4 and the upper photovoltaic panel 5, so as to facilitate the lower The photovoltaic panel 4 and the upper photovoltaic panel 5 are in use. At the same time, when the upper support frame 2 8 and the lower support frame 1 14 are rotated, the upper support frame 2 8 will form a triangle with the upper electric push rod 9 and the frame body 11, and the lower support frame 1 14 will form a triangle with the lower electric push rod 13 and the frame body 11. Since the triangle has stability, the upper rotating frame 6 can be supported by the upper support frame 1 7, and the lower rotating frame 3 can be supported by the lower support frame 2 15. When encountering strong winds, the upper electric push rod 9 and the lower electric push rod 13 are started to retract, so that the lower rotating frame 3 and the upper rotating frame 6 are overlapped and stored, reducing the area of ​​the photovoltaic panels, thereby reducing the impact of strong winds on the photovoltaic panels.
