[0028] The driving mechanism includes a second motor 10, a second motor 10 is fixedly arranged inside the third chute 31, a second threaded rod 11 is fixedly connected to the output end of the second motor 10, a second slide block 12 is threadedly connected to the second threaded rod 11, the second slide block 12 is slidably engaged in the third chute 31, a water tank 13 is fixedly connected to the upper end of the second slide block 12, a water storage block 16 is fixedly connected to one side of the water tank 13, a water pump 18 is fixedly arranged in the water tank 13, a hose 19 is fixedly connected to the output end of the water pump 18, one end of the hose 19 is fixedly connected to the top of the water storage block 16, a rectangular nozzle 17 is fixedly arranged at the lower end of the water storage block 16, a rectangular hole 30 is opened at the top of the first mounting plate 6, the water storage block 16 slides in the rectangular hole 30, a cover plate 14 is arranged on the top surface of the water tank 13, a card slot 15 is opened on the top surface of the water tank 13, and the cover plate 14 is engaged in the card slot 15;

[0029] Normally, the first mounting plate 6 is at the upper end of the shell 1, and the first motor 3 drives the first threaded rod 4 to rotate, and the first threaded rod 4 drives one of the first sliders 5 to move downward in the first slide groove 9, and one of the first sliders 5 drives the first mounting plate 6 to move, and the first mounting plate 6 drives the other first slider 5. By setting the round rod 8, the inner part of the other first slider 5 slides on the outer surface of the round rod 8, so that the first mounting plate 6 keeps moving downward horizontally under the action of the round rod 8, and the sponge block 7 is set, so that the first mounting plate 6 drives the sponge block 7 to wipe one side of the display screen body 2, and there is no need for manual wiping by the staff. A rectangular sponge is fixed on the upper end of the sponge block 7, and Velcro is set on the front and back sides of the rectangular sponge. Velcro is set on the inner side of the first mounting plate 6, so that the sponge block 7 is adhered to the inner side of the first mounting plate 6 under the action of the Velcro, so that the sponge block 7 can be disassembled by the staff, which is convenient for the staff to clean the sponge block 7;

[0030] A cover plate 14 is provided at the upper end of the water tank 13, and a silicone block is fixedly provided on the lower side of the cover plate 14, so that the cover plate 14 is clamped on the upper end of the water tank 13. Since silicone is a soft material, the cover plate 14 can be opened, and the water in the water tank 13 is sucked into the hose 19 under the action of the water pump 18. Since the interior of the water storage block 16 is hollow, the water flowing into the water storage block 16 is sprayed out through the rectangular nozzle 17, so that the sponge block 7 absorbs moisture, and there is no need for manual watering by the staff. The second motor 10 drives the second threaded rod 11 to rotate, and the second threaded rod 11 drives the second slider 12. The second slider 12 slides and is clamped in the third slide groove 31. By opening a rectangular hole 30 at the upper end of the first mounting plate 6, the water tank 13 drives the water storage block 16 to move, so that the sponge block 7 is evenly sprayed, and the first mounting plate 6 moves downward after spraying. At this time, the water storage block 16 is separated from the first mounting plate 6.

[0031] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a collection box 20 is inserted into the front side of the shell 1, and second slide grooves 21 are provided at both left and right ends of the collection box 20, and third sliders 22 are fixedly provided at both left and right ends of the inner side of the shell 1, and each third slider 22 is slidably engaged in the corresponding second slide groove 21, and a first handle 23 is fixedly provided on the front side of the collection box 20, and a third mounting plate 27 is provided on the right side of the shell 1, and a pair of plug rods 24 are fixedly provided on the left side of the third mounting plate 27, and a second mounting plate 25 is fixedly provided between the pair of plug rods 24, and slots 29 are provided through the right sides of the shell 1 and the collection box 20, and a pair of plug rods 24 are inserted in the slots 29, and a second handle 28 is fixedly provided on the right side of the third mounting plate 27, and a limiting slot 26 is provided inside the shell 1, and the second mounting plate 25 slides in the limiting slot 26;

[0032] A limiting groove 26 is provided inside the shell 1, and the second mounting plate 25 slides inside the limiting groove 26. By setting the collection box 20, the dust wiped is collected to prevent the dust from falling below and polluting the air. By setting two third sliding blocks 22 on the inner side of the shell 1, the collection box 20 can slide on the lower end of the shell 1, so that the collection box 20 can be pulled out and cleaned, which is convenient for the staff to use. Through the second handle 28, the third mounting plate 27 drives the two plug rods 24 to be pulled out, so that the collection box 20 is released. A silicone sheet is fixedly provided at one end of the plug rod 24. Since the silicone sheet is elastic, when the plug rod 24 is inserted into the inner side of the collection box 20, the silicone sheet unfolds, so that the plug rod 24 is fixed to the inner side of the collection box 20, so that the collection box 20 is fixed to the front side of the shell 1. By providing a limiting groove 26 in the shell 1, the second mounting plate 25 moves in the limiting groove 26 to prevent the plug rod 24 from falling out of the shell 1.

[0033] Specifically, the working principle and operation method of the utility model are as follows:

[0034] Step 1, open the cover plate 14, pour water into the water tank 13, start the water pump 18, so that the water in the water tank 13 is sucked into the hose 19, flows into the interior of the water storage block 16 through the hose 19, and is sprayed to the upper end of the sponge block 7 through the rectangular nozzle 17, and the second motor 10 is started. The second motor 10 drives the second threaded rod 11 to rotate, the second threaded rod 11 drives the second slider 12 to move, and the second slider 12 drives the water tank 13 to move. By opening a rectangular hole 30 at the upper end of the first mounting plate 6, the water tank 13 drives the water storage block 16 to move;

[0035] Step 2: Usually, the first mounting plate 6 is at the upper end of the housing 1, and the first motor 3 is started. The first motor 3 drives the first threaded rod 4 to rotate, and the first threaded rod 4 drives one of the first sliders 5 to move downward, and one of the first sliders 5 drives the first mounting plate 6 to move downward, and the first mounting plate 6 drives another first slider 5 to move. By setting the round rod 8, the first mounting plate 6 keeps moving horizontally downward. At this time, the water storage block 16 is separated from the first mounting plate 6, and the first mounting plate 6 drives the sponge block 7 to wipe up and down on one side of the display screen body 2, and the wiped dust falls into the collection box 20 at the lower end of the housing 1;

[0036] Step three, after cleaning, pull the third mounting plate 27 to the right to release the collection box 20, pull the collection box 20 out from the front side of the shell 1, and have the staff clean the dust in the collection box 20, remove the sponge block 7, and clean the sponge block 7.

[0037] The utility model solves the problem that it is inconvenient for workers to clean the LED display screen and cannot collect dust through the coordinated use of various components. The sponge block is sprayed evenly, so that the LED display screen is cleaned more cleanly without the need for manual cleaning by the workers. The collection box collects dust during use, which is convenient for the workers to clean.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
