[0023] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of the present application, the monitoring system also includes an emergency blocking component, which is arranged on the bottom cover 21 and located on the inner side of the monitoring box 1, and is used to perform emergency repair treatment on the connection of the air supply pipe. The monitoring module also includes a trigger unit, which is arranged on the turning handle 40. When the rotation speed of the turning handle 40 reaches an expected value, the trigger unit is controlled to work, and the trigger unit triggers the emergency blocking component to work.

[0028] After completing the connection work of the air supply pipe, by installing the bottom cover plate 21 in the through window 28, by controlling the linear motor 25 to be energized, the protective seat 26 is driven to move along the bottom cover plate 21 and be located on both sides of the connection of the air supply pipe. In the process of the shaft driving the handle 40 to rotate, the distribution sleeve 43 is acted upon by centrifugal force, and the distribution sleeve 43 moves toward the outside of the handle 40 along the slide groove 41 and the resistance rod 44, so that the distribution sleeve 43 and the resistance rod 44 are in contact at different positions. When the leakage speed of the air supply pipe causes the movement speed of the sliding plate 31 and the rotation speed of the handle 40 to reach the expected value, the resistance value of the access circuit reaches the expected value at this time and the electromagnetic block 24 is energized to repel each other, thereby driving the second piston rod 23 to move along the inflation pipe 22, thereby inputting the air in the inflation pipe 22 into the barrier airbag 27, and the barrier airbag 27 expands, thereby wrapping and sealing the connection of the air supply pipe, thereby urgently dealing with the leakage of the air supply pipe and waiting for maintenance personnel to disassemble and repair it.

[0031] It should be noted that the present embodiment is not limited to the above-mentioned cooperation mode of the first piston rod 15 and the sliding tube 11 to realize the inflation work in the sealing airbag 12, and a fan or an air pump can also be used directly instead, which are not listed here one by one.

[0032] In actual application, the air supply pipe is inserted into the air supply pipe installation sleeve 4 and extended into the monitoring box 1 for installation. By manually rotating the operating disk 2, the threaded rod 8 can be driven to rotate.

When the adjusting sleeve 3 continues to move, the first piston rod 15 can move relative to the sliding tube 11, so that the air in the sliding tube 11 is discharged into the sealing airbag 12 along the exhaust hole 19 and the connecting pipe 17, thereby controlling the expansion of the sealing airbag 12, achieving the sealing processing work between the air supply pipe and the air supply pipe installation sleeve 4, improving the monitoring accuracy of the whole device, achieving pipes of different diameters and improving the sealing of the whole device.
