First, the screen body 1 is connected to the wall through the bracket and bolts, and then the connecting cover 12 is placed on the outside of the screen body 1, and the connecting cover 12 is connected to the wall through the bolts. When the surface of the screen body 1 needs to be cleaned, the servo motor 13 is started, and the servo motor 13 will drive the threaded rod 15 to rotate. The square limit frame 16 will limit the square connecting block 17. Through the threaded cooperation between the threaded rod 15 and the square connecting block 17, the square connecting block 17 will move. When the double-headed gear column 18 is engaged with the rack frame 11, since the rack frame 11 is fixed, the double-headed gear column 18 will rotate. At this time, the connecting roller 19 and the cleaning cloth 10 will also rotate. The cleaning cloth 10 will move as a whole during the rotation process, and rub against the screen body 1 to remove dust on the surface of the screen body 1. Through the cooperation between the set double-headed gear column 18, the rack frame 11 and the cleaning cloth 10, the entire surface of the screen body 1 can be repeatedly cleaned, reducing the time spent by the staff to clean and wipe the screen body 1, and facilitating the use of the equipment by the staff.

[0028] Further, such as Figure 1 、 Figure 2 and Figure 3As shown, the top of the outer wall of the connecting cover 12 is fixedly connected to the water tank 2; the side wall of the water tank 2 is fixedly connected to a connecting hose 21; the outer wall of the connecting hose 21 is fixedly connected to a metal connecting pipe 22; the outer wall of the metal connecting pipe 22 is fixedly connected to a slider 23; the slider 23 is in sliding contact with the connecting cover 12; the outer wall of the metal connecting pipe 22 is fixedly connected to a support column 24; one end of the slider 23 is fixedly connected to the square connecting block 17; the top of the outer wall of the connecting cover 12 is fixedly connected to a limiting column 25. When sticky liquid adheres to the surface of the screen body 1, dust will also gather on the surface of the screen body 1, and ordinary wiping is difficult to wipe it off. Pour the cleaning liquid into the water tank 2, and the cleaning liquid will flow along the connecting hose 21 and the metal connecting tube 22 to the cleaning cloth 10. At this time, the inside of the cleaning cloth 10 will be filled with cleaning liquid. When the square connecting block 17 moves, the slider 23 and the metal connecting tube 22 will move accordingly, and the connecting hose 21 will bend accordingly. When the cleaning cloth 10 moves to the other side, the connecting hose 21 will bend along with the limiting column 25. Through the set limiting column 25 and the metal connecting tube 22, the inside of the cleaning cloth 10 can always be replenished with cleaning liquid. Through full contact with the cleaning liquid, the cleaning effect of the cleaning cloth 10 on the screen body 1 is further increased.

[0029] Further, such as Figure 2 and Figure 4 As shown, a plurality of springs 3 are fixed to the inner wall of the connecting cover 12; a support plate 31 is fixed to the outer wall of the spring 3; a scraper 32 is fixed to the outer wall of the support plate 31; the scraper 32 is in contact with the cleaning cloth 10; a water leakage block 33 is fixed to the side wall of the connecting cover 12; the water leakage block 33 is arranged below the scraper 32. When the equipment is working, when the cleaning cloth 10 moves to the side close to the scraper 32, the cleaning cloth 10 cleans the screen body 1 once. At this time, the inside of the cleaning cloth 10 is filled with a mixture of dust and cleaning liquid. When the cleaning cloth 10 continues to move until it contacts the scraper 32, the scraper 32 squeezes the surface of the cleaning cloth 10. During the rotation and movement of the cleaning cloth 10, the scraper 32 scrapes the sewage inside the cleaning cloth 10, which drips down through the leakage block 33, and the spring 3 will contract to move the scraper 32. The set spring 3 and scraper 32 can scrape the sewage inside the cleaning cloth 10, thereby reducing the situation where the sewage inside the cleaning cloth 10 pollutes the surface of the screen body 1 again when the cleaning cloth 10 returns.

[0030] Further, such as Figure 2 and Figure 5As shown, a pair of brush plates 4 are fixedly attached to the inner sidewalls of the protective plate 102; a plurality of bristles 41 are fixedly attached to the sidewalls of the brush plates 4; and the bristles 41 are in contact with the double-headed gear column 18. When the device is in operation, the double-headed gear column 18 moves, and at this time, the double-headed gear column 18 rubs against the bristles 41, which remove dust and large particles of impurities adhering to the surface of the double-headed gear column 18. The arrangement of the brush plates 4 and bristles 41 reduces the possibility of jamming or failure caused by dust and impurities during the mating of the double-headed gear column 18 and the rack frame 11, thereby improving the stability of the device.

[0031] Further, such as Figure 1 、 Figure 2 and Figure 4 As shown, a chute 5 is fixedly connected to the bottom of the outer wall of the connecting cover 12; a collection box 51 is slidably contacted on the inner wall of the chute 5. When the device is in operation, sewage will be stored in the collection box 51. By pulling the collection box 51, the collection box 51 can be quickly removed from the chute 5. When the collection box 51 is completely emptied, it is slid into the chute 5 to complete the installation. The chute 5 and the collection box 51 can be used to mix and collect the sewage generated during the cleaning process, thereby reducing the possibility of the sewage mixture dripping onto the ground and contaminating it.

[0032] Further, such as Figure 2 and Figure 3 As shown, the square limit frame 16 is made of a rigid material. The square limit frame 16 limits the movement direction of the square connecting block 17. By setting the square limit frame 16 of rigid material, the probability of the square limit frame 16 bending during long-term use of the device is reduced, and the situation of mismatch between devices caused by the bending of the square limit frame 16 is reduced.

[0033] Further, such as Figure 1 and Figure 2 As shown, an observation panel 7 is fixedly attached to the side wall of the water tank 2; the observation panel 7 is made of a transparent material. When the device is in operation, the operator can quickly check the remaining cleaning fluid in the water tank 2 through the observation panel 7. The presence of the observation panel 7 facilitates the operator to add cleaning fluid to the water tank 2 in a timely manner, thus facilitating the operator's use of the device.

[0034] Working principle: first connect the screen body 1 to the wall through the bracket and bolts, then place the connecting cover 12 on the outside of the screen body 1, and connect the connecting cover 12 to the wall through bolts. When the surface of the screen body 1 needs to be cleaned, start the servo motor 13, and the servo motor 13 will drive the threaded rod 15 to rotate. The square limit frame 16 will limit the square connecting block 17. The threaded rod 15 and the square connecting block 17 will cooperate with each other. At this time, the square connecting block 17 will move. When the double-headed gear column 18 is engaged with the rack frame 11, since the rack frame 11 is fixed, the double-headed gear column 18 will rotate. At this time, the connecting roller 19 and the cleaning cloth 10 will also rotate, and the cleaning cloth 10 will move as a whole during the rotation. The screen body 1 is rubbed with the screen body 1 to remove dust from the surface of the screen body 1. Through the cooperation between the double-headed gear column 18, the rack frame 11 and the cleaning cloth 10, the entire surface of the screen body 1 can be cleaned repeatedly, reducing the time spent by the staff to clean and wipe the screen body 1, and facilitating the use of the equipment by the staff. When the surface of the screen body 1 encounters sticky liquid adhesion, dust will also gather on the surface of the screen body 1, and ordinary wiping is difficult to wipe it off. Pour the cleaning liquid into the water tank 2, and the cleaning liquid will flow along the connecting hose 21 and the metal connecting pipe 22 to the cleaning cloth 10. At this time, the inside of the cleaning cloth 10 will be filled with the cleaning liquid. When the square connecting block 17 moves, the slider 23 and the metal connecting pipe 22 will move accordingly. The connecting hose 21 will follow the bending, and when the cleaning cloth 10 moves to the other side, the connecting hose 21 will bend along with the limiting column 25. Through the provided limiting column 25 and the metal connecting tube 22, the cleaning cloth 10 can always be replenished with cleaning liquid. Through full contact with the cleaning liquid, the cleaning effect of the cleaning cloth 10 on the screen body 1 is further increased. When the equipment is working, when the cleaning cloth 10 moves to the side close to the scraper 32, the cleaning cloth 10 cleans the screen body 1 once. At this time, the inside of the cleaning cloth 10 is filled with a mixture of dust and cleaning liquid. When the cleaning cloth 10 continues to move until it contacts the scraper 32, the scraper 32 squeezes the surface of the cleaning cloth 10. In the process of rotation and movement of the cleaning cloth 10, the scraper 32 will clean the screen body 1. The sewage inside the cleaning cloth 10 is scraped off and drips down through the leaking block 33, and the spring 3 will contract to move the scraper 32. The spring 3 and the scraper 32 can be used to scrape off the sewage inside the cleaning cloth 10, reducing the secondary contamination of the surface of the screen body 1 by the sewage inside the cleaning cloth 10 when the cleaning cloth 10 returns. When the device is working, the double-headed gear column 18 will move. At this time, the double-headed gear column 18 will rub against the bristles 41, and the bristles 41 will clean the dust and large particles attached to the surface of the double-headed gear column 18. The brush plate 4 and the bristles 41 are provided to reduce the jamming or failure caused by dust and impurities during the cooperation between the double-headed gear column 18 and the rack frame 11, thereby increasing the stability of the device. When the device is working,There will be sewage inside the collection box 51. By pulling the collection box 51, the collection box 51 can be quickly separated from the chute 5. When the collection box 51 is dumped, the collection box 51 is slid into the chute 5 to complete the installation. The chute 5 and the collection box 51 are provided, and the sewage generated during the cleaning process can be mixed and collected, thereby reducing the situation where the sewage mixture drips onto the ground and pollutes the ground. The square limit frame 16 limits the moving direction of the square connecting block 17. The rigid material of the square limit frame 16 reduces the probability of the square limit frame 16 bending when the equipment is used for a long time, and reduces the situation where the coordination between the equipment fails due to the bending of the square limit frame 16. When the equipment is working, the staff can quickly understand the remaining cleaning liquid in the water storage tank 2 through the observation plate 7. The observation plate 7 is provided to facilitate the staff to add the cleaning liquid inside the water storage tank 2 in time, which is convenient for the staff to use the equipment.
