The electromagnetic valve and the acceleration sensor 258 are connected by electrical signals. A manual valve 256 is fixedly connected to the back of the three-way pipe 255. The acceleration sensor 258 is an existing structure, and its model can be selected as BMA250E. The acceleration sensor 258 is connected to the electromagnetic valve by an external controller. The gas storage cylinder 257 stores some gas in the production process. If the wire rope of the steel wire retracting and releasing structure body 11 breaks, the sliding frame 25 will fall, and the acceleration sensor 258 can monitor the abnormal acceleration data. The solenoid valve is then controlled to open, and the pre-stored gas in the gas cylinder 257 is delivered to the hollow cylinder 251, pushing the sealing sliding member 254 to move toward the inner wall of the vertical slide groove frame 21, and the sliding frame 25 is fixed to the inner wall of the vertical slide groove frame 21 by the friction between the sealing sliding member 254 and the inner wall of the vertical slide groove frame 21, thereby avoiding the problem of further falling of the fire-fighting pipe. The manual valve 256 is controlled to open, so that the gas inside the sliding frame 25 can be released, and the fixing of the sliding frame 25 position can be released, which is convenient for the user's subsequent maintenance work.

Through the design of the fixed sleeve 284, the fire-fighting pipe can be temporarily supported. The stepper motor 281 is controlled to drive the rotating part 282 to rotate, so that the movable sleeve 283 is stuck on the top of the fixed sleeve 284. In conjunction with the fixed sleeve 284, the automatic fixing of the pipe can be completed, reducing manpower consumption. Through the design of the arc-shaped Velcro 1 29 and the arc-shaped Velcro 2 291, the user can replace the thickening sleeves 292 of different thicknesses on the inner wall of the movable sleeve 283 or the fixed sleeve 284 to suit fire-fighting pipes of different specifications.

[0025] Working principle: first place the fire-fighting pipe in the inner cavity of the fixed sleeve 284, and then control the stepper motor 281 to work, so that the movable sleeve 283 is stuck on the top of the fixed sleeve 284 to fix the fire-fighting pipe, and then control the wire retracting and releasing motor included in the main body 11 of the steel wire retracting and releasing structure to work, reel in the steel wire rope, and complete the lifting and hoisting of the fire-fighting pipe. If the steel wire rope breaks, the acceleration sensor 258 will monitor the fracture information through the overall falling acceleration data of the sliding frame 25, and then control the solenoid valve to open, and transport the pre-stored gas in the gas cylinder 257 to the hollow cylinder 251, pushing the sealing sliding member 254 toward the inner wall of the vertical slide groove frame 21, and temporarily locking the position of the sliding frame 25 inside the vertical slide groove frame 21.
