Problems solved by technology

In order to reduce the waste of water resources, many pipeline leakage detection methods have been proposed in recent years, including the traditional "audio-audio method", the automatic detection method of water leakage sound, and the related leak detection method. However, these methods have the following shortcomings: ①Experienced people are required to operate and the detection error is large, which consumes manpower, material and financial resources, and the positioning is not accurate; ②The detection is easily affected by the surrounding environment, and the sound of water leakage is easily covered up and cannot be detected, resulting in the inability to detect it in time and accurately Locate the location of the pipeline leak; ③The equipment is complex, difficult to install, and consumes a lot of energy
Therefore, there is a lack of a pipeline leakage device and monitoring method with simple equipment composition, easy installation, convenient operation, low investment, and high positioning accuracy.

Abstract

The invention discloses a chuck type displacement monitoring node device for a pipeline and a monitoring method, and relates to the technical field of underground pipeline net leakage detection, in particular to a method for monitoring pipeline leakage through a pipeline chuck. The aim is to solve the problems that in the prior art, a method for detecting tap water pipeline leakage is high in operation demand and low in positioning precision, and is affected by the ambient environment, installation is difficult, and energy consumption is high. The device comprises a monitoring device body andan information early warning device, pipeline leakage changes water stress in the pipeline, thrust or knocking and other changes are generated to trigger the monitoring device body, and generated water flow, flowing speed or pressure and other change information are transmitted to the information early warning device to emit an alarm signal. The device is not limited by the terrain, landform, energy shortage and other conditions, and is easy to install, accurate in positioning, small in investment, low in consumed electric energy, high in utilization rate, diversified in patrolling mode and high in endurance; the chuck type displacement monitoring node device for the pipeline and the monitoring method are suitable for pipeline leakage detection.

Description

technical field [0001] The invention relates to the technical field of underground pipeline network leakage detection, in particular to a method for monitoring pipeline leakage with a pipeline chuck type. Background technique [0002] Using pipelines to transport tap water is not only safe and convenient, but also has a large transportation volume, and has little pollution to the environment. Therefore, pipelines have become an important mode of transportation for tap water. In recent years, with the development of the economy and the continuous expansion of the scale of cities and towns, the number of underground water supply pipelines is also increasing. However, due to the corrosion of pipelines and man-made damage, leakage of urban water supply pipelines occurs from time to time, which not only wastes a lot of water. Water resources have affected the natural environment of the surrounding areas, and caused loose soil, causing houses to collapse, bringing huge hidden dang...
