[0037] When the cleaning cotton 20 moves to the lowest point, the starting motor 2 14 drives the rotating shaft 15 to rotate in the opposite direction, so that the cam 16 has no squeezing effect on the interlocking plate 17. At this time, under the elastic force of the reset spring 21, the interlocking plate 17 can be driven to move to the side away from the curtain wall body 2, and the interlocking plate 17 drives the movable plate 18 to move, and the movable plate 18 drives the mounting plate 19 to move, and the mounting plate 19 drives the cleaning cotton 20 to move, so that the cleaning cotton 20 is separated from the curtain wall body 2. At this time, by starting the motor 1 3 again to rotate in the opposite direction, the cleaning cotton 20 moves upward to the highest point, and repeating the above operation, the curtain wall body 2 can be cleaned reciprocatingly.

[0038] It is supplemented here that, since the cleaning cotton 20 is separated from the curtain wall body 2 when moving upward, it will not cause pollution to the curtain wall body 2 after wiping, thus avoiding affecting the cleaning effect.

The limiting groove on the wall, the limiting strip 29 fixedly mounted on the side wall of the threaded tube 28 and sliding in the inner cavity of the limiting groove, the threaded tube 28 can be limited by the mutual cooperation between the limiting strip 29 and the limiting groove, so that the threaded tube 28 can maintain vertical linear movement; the top end of the rotating shaft 15 extends to the inner cavity of the connecting shell 23, and the rotating shaft 15 is rotatably mounted on the side wall of the connecting shell 23, and the outer edge of the rotating shaft 15 near the top end and the inner wall of the threaded tube 28 are both provided with threads, and the outer edge of the rotating shaft 15 near the top end and the inner wall of the threaded tube 28 are meshed with each other.

[0040] When the motor 2 14 is started to make the cleaning cotton 20 contact with the surface of the curtain wall body 2, the rotating shaft 15 can drive the threaded tube 28 to move downward, and the threaded tube 28 drives the sealing plug 26 to move downward, so that the sealing plug 26 unblocks the water inlet pipe 25. Since the other end of the water inlet pipe 25 is connected to the tap water pipe, the tap water can enter the inner cavity of the connecting shell 23 along the inner cavity of the water inlet pipe 25 and be sprayed out through the nozzle 24, so that the clean water is sprayed on the surface of the curtain wall body 2, thereby cleaning the curtain wall body 2, thereby further improving the cleaning effect of the curtain wall body 2.

[0041] When the cleaning cotton 20 moves upward, the starter motor 214 rotates in the opposite direction. At this time, the rotating shaft 15 drives the threaded tube 28 to move upward, and the threaded tube 28 drives the sealing plug 26 to move upward, so that the sealing plug 26 is reset, and then the sealing plug 26 seals the water inlet pipe 25, so that the device can spray water while wiping, which is conducive to cleaning the dust on the surface of the curtain wall body 2 more thoroughly, and the nozzle 24 is arranged above the cleaning cotton 20, so that the cleaning cotton 20 can also be rinsed when spraying water, to avoid a large amount of dust adhering to the surface of the cleaning cotton 20 and affecting the cleaning effect.

[0044] When the motor 3 drives the first threaded rod 4 to rotate, it can drive the active bevel gear 7 to rotate, and the active bevel gear 7 drives the driven bevel gear 8 to rotate, and the driven bevel gear 8 drives the second threaded rod 9 to rotate, and the scraper 10 is driven to move by the second threaded rod 9. The forward and reverse rotation of the motor 3 makes the second threaded rod 9 rotate forward and reverse, thereby driving the scraper 10 to reciprocate along the axial direction of the second threaded rod 9. The movement of the scraper 10 can push the sewage generated by cleaning to both sides, so that the sewage flows to the drainage holes on both sides, thereby realizing the rapid discharge of the sewage and avoiding the sewage from being trapped in the inner cavity of the second installation groove.
