A threaded rod 6 is rotatably installed on the top surface of the equipment box 1, and a threaded sleeve 5 is fixedly installed on the side surface of the movable frame 4. The threaded rod 6 is threadedly sleeved inside the threaded sleeve 5. A bevel gear 40 is meshed on the outer surface of the bevel gear 39. A ratchet group 34 is provided above the bevel gear 40, and the bevel gear 40 is installed at the bottom end of the ratchet group 34. A pulley 35 is installed on the top of the ratchet group 34, and a pulley 36 is fixedly sleeved on the outer surface of the threaded rod 6.

A plate brush 42 is fixedly installed on one side surface of the magnet frame 41, and a sponge brush 45 is fixedly installed on one side surface of the magnet frame 2 44.

[0037] In the present embodiment: by controlling the servo motor 12 to start, when the servo motor 12 starts, it drives the transmission shaft 10 to rotate inside the equipment box 1, drives the threaded rod 1 6 to rotate, and can drive the movable frame 1 4 to move downward under the action of the thread, and can synchronously drive the movable frame 2 43 to move downward, when the movable frame 1 4 and the movable frame 2 43 move downward, they can drive the brush 42 to scrape off the dust on the outer surface of the protective cover 3, and the sponge brush 45 can scrape off the mist generated on the inner wall of the protective cover 3, thereby achieving the purpose of self-cleaning of the protective cover 3.

[0038] A protective box 31 is fixedly installed on one side surface of the equipment box 1, the servo motor 12 is fixedly installed inside the protective box 31, a vertical plate 32 is fixedly installed on the top surface of the protective box 31, a fixing frame 2 33 is fixedly installed on one side surface of the vertical plate 32, and a ratchet group 34 is installed inside the fixing frame 2 33. The protective box 31 can protect the servo motor 12 on the one hand, and on the other hand, since the vertical plate 32 is installed on the top surface of the protective box 31 and the ratchet group 34 is installed inside the fixing frame 2 33, the ratchet group 34 can be stably installed.

[0039] The gas injection assembly includes an installation box 18, and the number of the installation boxes 18 is two. The two installation boxes 18 are fixedly installed inside the equipment box 1 and are symmetrically arranged. An air bag 19 is fixedly installed inside the installation box 18. The inside of the installation box 18 is movably connected with an active clamping plate 20. One side surface of the active clamping plate 20 is bonded to one side surface of the air bag 19. When the active clamping plate 20 moves toward the direction of the servo motor 12, it can assist in driving the air bag 19 to absorb the inert gas into the inside of the air bag 19;

[0040] An air storage box 2 is fixedly installed on the bottom surface of the equipment box 1, and a connecting pipe 22 is fixedly connected to one side surface of the air storage box 2. There are two connecting pipes 22, and the other ends of the two connecting pipes 22 are fixedly connected to one side surface of the air bag 19 respectively. A connecting pipe 24 is fixedly connected between the two air bags 19, and a connecting pipe 25 is fixedly connected to the outer surface of the connecting pipe 24. One end of the connecting pipe 25 is connected to an air intake pipe 27, and a pipe connector 28 is arranged between the air intake pipe 27 and the connecting pipe 25. The air intake pipe 27 and the connecting pipe 25 are fixedly connected through the pipe connector 28 to achieve quick connection and disassembly between the air intake pipe 27 and the connecting pipe 25, that is, it is convenient to connect with the connecting pipe 25 after the protective cover 3 is covered. A one-way valve 26 is fixedly installed on the outer surface of the connecting pipe 25, and a one-way valve 23 is fixedly installed on the outer surface of the connecting pipe 22. By setting the one-way valve 23 and the one-way valve 26, the normal circulation of the inert gas can be controlled, and turbulence problems will not occur.

[0041] A threaded rod 14 is rotatably installed inside the equipment box 1, and a connecting frame 13 is fixedly installed on one end of the threaded rod 14. The transmission shaft 10 and the threaded rod 14 are fixedly connected through the connecting frame 13. A threaded sleeve 15 is threadedly sleeved on the outer surface of the threaded rod 14, and an extension rod 16 is fixedly installed on the outer surface of the threaded sleeve 15. A connecting plate 17 is fixedly connected to a side surface of the extension rod 16, and one end of the connecting plate 17 is fixedly connected to a side surface of a movable clamping plate 20. Limiting grooves are provided on the inner walls of both sides of the equipment box 1, and one end of the extension rod 16 is movably clamped in the inside of the limiting groove, which can limit the extension rod 16 to prevent the threaded sleeve 15 from rotating on the outer surface of the threaded rod 14 during the rotation of the threaded rod 14.

[0042] In this embodiment: when the servo motor 12 rotates counterclockwise, the threaded sleeve 15 and the extension rod 16 can be driven to move away from the servo motor 12 under the action of the thread, and the movable clamping plate 20 can be driven to move toward the inside of the installation box 18, squeezing the airbag 19, and the maintenance gas inside the airbag 19 will enter the inside of the connecting pipe 24, and then enter the inside of the connecting pipe 25 through the connecting pipe 24, and finally enter the inside of the protective cover 3 through the air inlet pipe 27, inputting the maintenance gas into the inside of the protective cover 3, thereby achieving the purpose of injecting maintenance gas into the inside of the protective cover 3 to protect the protective cover 3.

[0043] The top surface of the protective cover 3 is fixedly connected with an exhaust pipe 29, and a one-way valve 30 is fixedly installed on the outer surface of the exhaust pipe 29. As the maintenance gas is injected into the interior of the protective cover 3, the interior of the protective cover 3 is in a relatively sealed state after the protective cover 3 is installed. The injection of new gas will discharge the gas originally covered in the protective cover 3 to the outside through the exhaust pipe 29, thereby alleviating the problem that the humid air covered in the protective cover 3 is prone to form water mist on the inner wall of the protective cover 3.

[0044] Specifically, the working process or working principle of the self-cleaning exhibition stand for art education is as follows: when in use, firstly, the paintings to be displayed are adhered to the outer surface of the exhibition board 9, and then the protective cover 3 is set on the top surface of the equipment box 1, that is, the exhibition board 9 is set inside the protective cover 3 to play a protective role. When the outer surface of the protective cover 3 is covered with dust due to long-term placement, it is only necessary to control the servo motor 12 to start. When the servo motor 12 is started, the transmission shaft 10 is driven to rotate inside the equipment box 1. During the clockwise rotation, the bevel gear three 39 can be driven to rotate. Under the meshing action of the bevel gear three 39 and the bevel gear four 40, the bevel gear three 39 installed on the top of the ratchet group 34 can be driven to rotate, and then the transmission between the pulley one 35, the pulley two 36 and the transmission belt 37 drives the threaded rod one 6 to rotate on the top surface of the equipment box 1. When the threaded rod one 6 rotates, since a threaded sleeve one 5 is fixedly installed on one side surface of the movable frame one 4, the movable frame one 4 can be driven to move downward under the action of the thread, and the movable frame one 4 and the movable frame one 4 are connected. The interior of the movable frame 2 43 is respectively fixed with a magnet frame 1 41 and a magnet frame 2 44, so that the movable frame 1 4 and the movable frame 2 43 can be adsorbed on the outer wall and the inner wall of the protective cover 3, and when the movable frame 1 4 moves downward, the movable frame 2 43 can be synchronously driven to move downward. In addition, since the interior of the movable frame 1 4 and the movable frame 2 43 is respectively installed with a scrub brush 42 and a sponge brush 45, and one side surface of the scrub brush 42 and the sponge brush 45 is tightly fitted with the outer wall and the inner wall of the protective cover 3, when the movable frame 1 4 and the movable frame 2 43 move downward, the movable frame 1 4 and the movable frame 2 43 can be moved downward. During the downward movement of the movable frame 3, the plate brush 42 can be driven to scrape off the dust on the outer surface of the protective cover 3, and the sponge brush 45 can scrape off the mist generated on the inner wall of the protective cover 3, thereby achieving the purpose of self-cleaning of the protective cover 3. After the movable frame 1 4 and the movable frame 2 43 are moved to the bottom of the protective cover 3, the threaded rod 1 6 can be manually rotated to return the movable frame 1 4 and the movable frame 2 43 to the original position. During the return process, the inner and outer walls of the protective cover 3 can be cleaned again, thereby further improving the protection effect.

[0045] When the servo motor 12 drives the transmission shaft 10 to rotate counterclockwise inside the equipment box 1, it can drive the threaded rod 14 to rotate synchronously inside the equipment box 1. Due to the setting of the ratchet group 34, when the servo motor 12 rotates counterclockwise, it will not drive the threaded rod 16 to rotate. When the threaded rod 14 rotates counterclockwise, it can drive the threaded sleeve 15 and the extension rod 16 to move away from the servo motor 12 under the action of the thread. During the movement, it can drive the movable clamping plate 20 to move toward the inside of the installation box 18, so as to adjust the airbag. 19 is squeezed. During the squeezing process, the maintenance gas inside the airbag 19 will enter the inside of the connecting pipe 24, then enter the inside of the connecting pipe 25 through the connecting pipe 24, and finally enter the inside of the protective cover 3 through the air inlet pipe 27, inputting the maintenance gas into the protective cover 3. Conversely, when the servo motor 12 rotates clockwise, that is, in the process of cleaning the protective cover 3, it can drive the threaded sleeve 2 15 to move in the direction of the servo motor 12, and re-inhale the maintenance gas inside the air storage box 2 into the airbag 19 for the next injection;

[0046] When the servo motor 12 rotates clockwise or counterclockwise, it will drive the rotating shaft 7 to rotate through the bevel gear 11 and the fixing frame 8. Since the display board 9 is fixedly mounted on the outer surface of the rotating shaft 7 through the fixing frame 8, the display sample will be displaced under the rotation of the display board 9, which is convenient for adjusting the position of the display painting.

[0047] It should be noted that the servo motor 12 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
