The self-checking function of the device is realized by matching the gas control component 6, the gas storage bottle 7, the central control equipment 10 and the detection equipment main body 9.

In the process that the stress rod 932 rotates along with the detection barrel 91, under the action of the spring, the stress rod 932 axially moves along the tooth-shaped surface of the rotating wheel 931, after the stress rod 932 moves to the maximum radius position of the tooth-shaped surface, the stress rod 932 is separated from the tooth-shaped surface, under the action of reverse elastic thrust of the spring, the stress rod 932 is instantly pushed to abut against the tooth root of the next tooth-shaped surface, so that the connecting frame 933, the moving ring 934 and the impact rod 935 are driven to axially move, the impact rod 935 impacts the elastic filter cover 922, and after the elastic filter cover 922 is impacted, dust on the elastic filter cover 922 is vibrated and vertically falls. After the self-cleaning operation is finished, the first push rod 4 is retracted under the control of the central control device 10, so as to drive the detecting cylinder 91 to rotate back to the initial position, and meanwhile, the force-bearing rod 932 drives the rotating wheel 931 to reset, so as to prepare for the subsequent cleaning action.
