meanwhile, when the first exhaust hole 22 and the lifting hole 451 are communicated, the baffle 45 drives the second rack 453 to rotate together, after the second rack 453 moves a certain distance, the second rack 453 is meshed with the second gear 72, then the crown gear 6 rotates through the second gear 72, and then the third exhaust hole 61 is communicated with the second exhaust hole 25, so that the second exhaust hole 25 starts to reversely exhaust after the first exhaust hole 22 reversely pushes the pipeline endoscope 1 to change the position, and the pipeline endoscope 1 is accelerated to pass through the bent part of the pipeline;
then when the exhaust hole II 25 performs exhaust reverse pushing, the air exhausted by the exhaust hole II 25 can blow the paddles 83 at two sides at the moment, and can drive the rotation of the rotation shaft II 82 along with the rotation of the paddles 83, and the rotation shaft II 82 can wind the winding protective film 81 after rotating, so that the protective film 81 in front of the camera 11 can be wound, and the water stain in the fire-fighting pipeline can be prevented from affecting the camera 11;
after the lifting hole 451 moves below the first exhaust hole 22, the high pressure gas in the inflation cavity 24 can push the lifting tube 9 to move toward the first exhaust hole 22, and the lifting tube 9 can rotate in a rotating manner along with the high pressure gas flowing through the second blade 91, and then impurities in the first exhaust hole 22 can be cleaned through the anti-blocking frame 93.
