When the support frame 21 supports the air suction pipe 33, the air pump 32 is started to extract air through the air suction pipe 33. The top of the air pump 32 is fixedly connected to the air suction pipe 33. When the air suction pipe 33 extracts air, the air will pass through the suction disk 34 to the inside of the air suction pipe 33. The end of the air suction pipe 33 away from the air suction pump 32 is fixedly connected to the suction disk 34, which effectively extracts air and filters the air through the filter disk 5 to filter out dust in the air, making the air more accurate during detection.

[0026] One end of the delivery pipe 35 away from the guide pipe 36 is fixedly connected to the surface of the vacuum pump 32, and then enters the vacuum pump 32 through the vacuum pipe 33.

When the right-angle plate 56 moves, it drives the cleaning ring 60 to shrink on the surface of the filter disc 5 in a direction close to each other, and cleans the dust on the surface of the filter disc 5. Finally, the dust is pushed into the interior of the storage box 6 through the cleaning ring 60, so that the surface of the filter disc 5 is effectively cleaned, the labor of the staff is reduced, and the efficiency of using the gas storage tank 1 is improved.

[0028] The inner wall of the threaded frame 51 is rotatably connected to the surface of the threaded rod 11, the surface of the groove plate 54 is fixedly connected to the inner wall of the gas storage tank 1, the end of the right-angle plate 56 is fixedly connected to the end of the elastic plate 57, the surface of the sealing plate 59 is rotatably connected to the inner wall of the filter disc 5, and the bottom of the cleaning ring 60 contacts the surface of the filter disc 5.

When the threaded ring 12 moves, it will drive the lower pressing plate 13 to move downward. When the lower pressing plate 13 moves, it will squeeze the limiting elastic rod 14. When the limiting elastic rod 14 is squeezed, it will shrink downward. When it shrinks to a certain position, it will limit the lower pressing plate 13. The limiting elastic rod 14 prevents the lower pressing plate 13 from contacting the top of the gas outlet tank 1. When the lower pressing plate 13 moves, it will push the pushing rod 15 to move downward. When the pushing rod 15 moves, it will push the telescopic plate 16 to shrink in the direction of approaching each other. When the telescopic plate 16 moves The right-angle rod 17 will be driven to move in the direction of approaching each other. When the right-angle rod 17 moves, it will push the force-bearing rod 18 to move in the direction of approaching each other. When the force-bearing rod 18 moves, it will push the lower pressure frame 19 to move downward. When the lower pressure frame 19 moves, it will push the stabilizing plate 20 to move downward. When the stabilizing plate 20 moves, it will contact the ground. The large contact area between the stabilizing plate 20 and the ground makes the gas storage tank 1 stand more firmly. When the telescopic plate 16 contracts, it will drive the support frame 21 to move in the direction of approaching each other and contact with the surface of the exhaust pipe 33. When the support frame 21 supports the exhaust pipe 33, the exhaust pump 32 is started to pump air through the exhaust pipe 33. When the air extraction pipe 33 extracts air, the air will pass through the suction plate 34 into the interior of the air extraction pipe 33, and then enter the air extraction pump 32 through the air extraction pipe 33. When the air extraction pump 32 absorbs air, it will be transmitted to the interior of the delivery pipe 35. When the delivery pipe 35 absorbs air, it will be transmitted to the interior of the guide pipe 36. Finally, the air is transmitted to the interior of the air storage tank 1 through the guide pipe 36. The air is filtered by the filter plate 5. When the threaded rod 11 rotates, the threaded frame 51 will move downward. When the threaded frame 51 moves, it will drive the sliding frame 52 to slide downward on the inner wall of the groove plate 54 and squeeze the elastic telescopic rod 53. When the sliding frame 52 moves When the filter disc 5 is moved, the driven rod 55 is pushed to move downward, and when the driven rod 55 moves, the right-angle plate 56 is pushed to move in the direction of approaching each other. When the right-angle plate 56 moves, the cleaning ring 60 is driven to shrink in the direction of approaching each other on the surface of the filter disc 5, and the dust on the surface of the filter disc 5 is cleaned. When the right-angle plate 56 moves, the elastic plate 57 is squeezed, and when the elastic plate 57 is squeezed, it bends downward. When the elastic plate 57 bends, it pushes the push rod 58 to move downward.
