A kind of pipeline leak detection device and detection method thereof

Abstract

A pipeline leak detection device and its detection method, including a listening robot walking inside the pipeline, and a sealing unit sealed and fixed at both ends of the pipeline, wherein the blocking unit is provided with a signal connected to the listening robot wireless signal The transceiver unit; the listening robot includes a cylindrical shell, and the circumferential outer wall of the cylindrical shell is evenly distributed and hingedly connected with a support rod and a plurality of electric pen-type push rods; the blocking unit includes an annular base, a rubber Sealing bag and end sealing plate, the annular base is sealed and coaxially fixed on the opening end of the pipeline, and one side of the annular base is fixed to the end sealing plate with axial bolts; the outer periphery of the rubber sealing bag is formed by the annular base and The end sealing plate is clamped and sealed. The detection device and its detection method can effectively solve the problem that the rubber sealing bag is washed out by the pipeline pressure, and can run along the inner wall of the pipeline above the axis of the pipeline, and its operation will not be disturbed by the pipeline effusion and sediment, shortening the time The detection waiting time is improved, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline maintenance, in particular to a pipeline leak detection device and a detection method thereof. Background technique [0002] Pipelines are water supply and drainage facilities often used in municipal engineering. In the prior art, when there is leakage in water supply and drainage pipes, it is first necessary to determine the infiltration point or leakage point. At this time, both ends of the pipe need to be blocked to prevent further water flow. damage, and pipeline sealing can save the cost of pipeline maintenance; however, the current sealing technology is too complicated, inconvenient to operate, and consumes a lot of time and manpower; moreover, the current method of sealing pipelines with rubber sealing bags cannot meet the requirements of relatively high pressure in pipelines. In severe cases, especially if the sealing bag is not tightly sealed and the installation is not firm, the rubber ...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a pipeline leak detection device and its detection method, which can effectively solve the problem that the rubber seal bag is flushed out by pipeline pressure, and can It runs along the inner wall of the pipeline above the axis of the pipeline, and its operation will not be disturbed by pipeline effusion and sediment, which shortens the detection waiting time and improves the detection accuracy.
