The working principle of the invention is as follows: when the detection device is used, the upper sealing cover 301 needs to be rotated anticlockwise, so that the sealing cover 301 gradually moves upwards under the action of the thread 101b and is separated from the detection tank 101a, at the moment, the sealing cover 301 needs to be placed below the detection tube, so that the clamping block 304b is aligned with the second butting groove 203b, the clamping block 304b can be clamped into the second butting groove 203b under the action of the elastic force of the second spring 304d to finish butting, and at the moment, the sealing cover 301 needs to be rotated anticlockwise, so that the sealing rod is gradually fixed with the detection tank 101a along the thread 101 b;
When the clamping block 304b is lowered into the second docking slot 203b and the sealing cover 301 is rotated, the clamping block 304b drives the docking plate 203a and the rotating rod 202a to rotate through the second docking slot 203b, the rotating rod 202a drives the extrusion rod 208a to rotate, and the extrusion rod 208a moves along the surface of the extrusion rod 206c through the pulley 208b when rotating, meanwhile, the extrusion rod 206c is irregularly arc-shaped, so the pulley 208b extrudes the extrusion rod 206c and the connecting plate 206b, so that the connecting plate 206b turns over along the pin shaft 206a, and the connecting plate 206b and the supporting component 207 are pushed out of the movable slot 101f, and when the follow-up gas is injected into the expansion rod, the gas enters the expansion rod along the rotating rod 202a, the sealing sleeve 202d, the first guide tube 204, the telescopic tube 205 and the second guide tube 206d, so that the first expansion rod 207b gradually stretches, and the bottom end of the first expansion rod 207b contacts the ground, and external support is added to the device;
When the protective clothing to be detected needs to be fixed, the positioner 106h is only required to be opened so as to loosen the second clamping plate 106g to fix the first clamping plate 106e, at the moment, the first clamping plate 106e and the second clamping plate 106g are overturned along the second rotator 106f and the hinge, then the integral positions of the first clamping plate 106e and the second clamping plate 106g are adjusted along the first rotator 106d, at the moment, cloth can be uniformly paved above the detection tank 101a, the first clamping plate 106e and the second clamping plate 106g are overturned upwards along the first rotator 106d, and the second clamping plate 106g and the first clamping plate 106e are overturned along the hinge and the second rotator 106f, so that the first clamping plate 106e and the second clamping plate 106g are clamped outside the cloth and the detection tank 101a, and at the moment, the first clamping plate 106e and the second clamping plate 106g are fixed through the positioner 106h, so that the cloth is completely fixed;
when the gas enters the detection tank 101a, part of the gas enters the four first guide pipes 204 along the rotating rod 202a, part of the gas enters the expansion airbag 101d along the air inlet cover 101e, the rest of the gas is discharged along the detection port 101c above the detection tank 101a, and when the gas enters the air inlet cover 101e, the expansion airbag 101d deforms and gradually expands outwards, so that the cloth is extruded to be in contact with the sealing sleeve 202d, and the cloth is completely fixed.
