Pipeline leak detection device, system and method

Abstract

A pipeline leakage detection device comprises a sealing shell, an elastic film is connected on the outer surface of an upper shell, and a first vent valve is arranged on the upper shell covered by theelastic film. A second vent valve is arranged on the elastic film, and a lower shell is equipped with a compressed air bag, a data acquisition module, a controller, a GPS signal transmitting-receiving module and a battery. A pipeline leakage detection system comprises the pipeline leakage detection device put in a pipeline, and an intermediate server and a terminal intelligent server which are arranged outside the pipeline. Based on the above device and the system, the present invention also relates to two different pipeline leakage detection methods. The beneficial effects of the present invention are that the pipeline leakage detection device is small and variable in size and simple in structure, is simple to use, and can go down and rise flexibly; the system is easy to deploy and monitor and is not easy to interfere, is high in detection efficiency and leakage detection positioning precision; the two leakage detection methods are simple to operate, and can detect the positions of all leakage ports rapidly.

Description

technical field [0001] The invention relates to a pipeline leak detection device, system and method, and belongs to the technical field of pipeline leak detection. Background technique [0002] The scale of my country's underground pipeline network is very large, and the leakage of underground pipeline network will not only cause economic losses, but also easily cause various safety accidents. Taking the water pipe network as an example, the average tax evasion rate of the water pipe network in my country is about 30%. [0003] Traditional pipeline leak detection methods include passive leak detection method, audio leak detection method, related leak detection method, automatic leak detection method and partition leak detection method. In general, the above pipeline leak detection methods have disadvantages such as time-consuming and labor-intensive, low detection efficiency, and inaccurate leak location. Specifically, the passive leak detection method needs to be used aft...
