[0041] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0042] Embodiment: When in use, the driving assembly is started, the second motor 28 drives the main gear 29 to rotate, the main gear 29 is meshed with the sub-gear 30, so that the screw 5 rotates, and the lifting column 6 screwed on the screw 5 rises to a suitable height under the guidance of the guide block 35 and the guide groove 34;

[0043] Start the adjustment assembly, the first motor 31 drives the driving gear 32 to rotate, the driving gear 32 meshes with the gear ring 33 on the lower wall of the turntable 7, so that the turntable 7 rotates 180°, and the mounting frame 9 and the placement plate 10 are rotated to the outside of the housing 1, and then the second motor 28 is reversed, and the lifting column 6 drives the mounting frame 9 and the placement plate 10 to descend to a suitable position;

[0044] Place the gas cylinders on the conveying roller 11 of the placement plate 10, and push them one by one to the side close to the mounting frame 9. The setting of the conveying roller 11 can facilitate the pushing of the gas cylinders. Then start the clamping assembly, rotate the wire drawing rod 13, so that the slider 14 on the wire drawing rod 13 moves relatively, drive the clamping plate 16 and the clamping claw 17 close to the gas cylinder, and use the V-shaped clamping groove in the clamping claw 17 to clamp multiple gas cylinders at the same time;

[0045] The driving assembly is started again to raise the lifting column 6 to a certain height, and then the adjusting assembly is started to rotate the turntable 7 by 180°, so that the mounting frame 9 and the placement plate 10 are rotated above the shell 1. The driving assembly then controls the lifting column 6 to descend, so that the gas cylinder descends to the inside of the shell 1 filled with water, and the inflation nozzle 4 is connected to the gas cylinder;

[0046] Turn on the gas source, and the gas enters the gas cylinder through the gas pipe 3 and the inflation nozzle 4 to inflate the gas cylinder. During the inflation process, observe whether bubbles are generated inside the shell 1 to determine whether there is an airtightness problem in the gas cylinder;

[0047] After the test is completed, open the drain pipe 36 to drain the water inside the housing 1, the driving component controls the lifting column 6 to rise, the adjusting component rotates the turntable 7 180°, and rotates the mounting frame 9 and the placement plate 10 to the outside of the housing 1. Loosen the clamping component and remove the gas cylinder from the placement plate 10;

[0048] During the lifting process of the lifting column 6, the vertical rod 24 drives the cleaning frame 18 to move together through the insertion mechanism. Under the action of the spring 21, the cleaning plate 20 makes the brush 22 always closely fit the inner wall of the shell 1 to clean the inner wall of the shell 1. If the cleaning frame 18 or the brush 22 needs to be replaced, the positioning bolt 27 can be unscrewed, the vertical rod 24 can be pulled out of the insertion tube 25, and the cleaning frame 18 can be disassembled and replaced.
