[0068] Manually go to the specific location of the leak to carry out repairs.

[0069] The water pipe leakage detection device provided by the present invention has the following beneficial effects:

[0070] By detecting the vibration of the inner wall of the liquid delivery pipeline when the liquid flows and monitoring the change of vibration frequency, it is possible to determine whether the liquid delivery pipeline has leakage or other abnormal phenomena. According to the location area where the monitor is arranged, the area where the abnormality occurs is determined, an alarm command is issued, and then personnel are sent to the leakage area to eliminate the leakage. This reduces liquid loss and saves energy.

[0071] By designing the sealing structure, the gaps at the connection of each component are compressed to make the inside of the leak detection device waterproof and protect the internal parts. The gap connected to the outside is filled by the sealing ring, so that the inside of the leak detection device is isolated from the external water vapor, but it does not hinder the normal function of each component, and the leak detection device is sealed and waterproof as a whole.
