[0035] The working principle of the above embodiment is:

[0036] First, the operator flips open the first shell 1 and the second shell 2 of the device through the rotating shaft 3, so that the opening part of the device is aligned with the water pipe to be tested. Then, the operator puts the device on the water pipe to ensure that the water absorbent pad 11 and the inner tube 10 of the device are tightly fitted on the outer wall of the water pipe. After the device is put on the water pipe, the operator rotates the fixing bolts 6 and fixes them with nuts 7 to fix the first shell 1 and the second shell 2 tightly on the water pipe. At the same time, the sealing strip 13 of the device will play an additional sealing role to ensure that the device is tightly connected to the water pipe and the pressure transmitter is The sensor 8 will continuously monitor whether the water pipe expands and the pressure change of the inner pipe 10. If the water pipe leaks, the pressure sensor 8 will detect the pressure change. At the same time, the absorbent pad 11 will absorb moisture from the outside of the water pipe, and the humidity sensor 17 will detect the change in humidity inside the absorbent pad 11. If the pressure sensor 8 detects that the pressure of the inner pipe 10 is abnormal or the humidity sensor 17 detects that the humidity inside the absorbent pad 11 is abnormal, the control module 18 of the device will determine that there is a leak in the water pipe. At this time, the device will trigger the alarm light 15 to light up, reminding the operator to deal with it in time.
