Pipe detection device

Abstract

The implementing mode of the invention provides a pipeline detection device. The device belongs to the field of detection and includes a shell as well as a machine core; the shell is matched with a pipeline flange and ensures the machine core to be contacted with a medium in the pipeline, thereby judging whether the pipeline is leaked or not by an infrasonic signal inside the detection pipeline. The device has the advantages of simple structure, long detection distance, accurate detection and lower cost.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a pipeline detection device. Background technique [0002] With the development and progress of society, the process of urbanization in various countries is getting faster and faster, and the use of pipelines is also increasing. However, most pipelines are set in uninhabited areas or buried deep underground, resulting in leakage of pipelines. It can only be known in large cases. In order to solve the above technical problems, the prior art provides a pipeline detection device, which detects the pipeline through an externally attached acoustic wave sensor to determine whether the pipeline is leaking. The device is installed outside the pipeline and detects the acoustic signal of the pipeline wall to determine Whether the pipe is leaking. [0003] In the process of realizing the present invention, the inventor finds that the prior art has the following problems: [0004] 1. Because it...

Problems solved by technology

[0004] 1. Because it judges whether the pipeline is leaking by detecting the acoustic signal of the pipeline wall, and is installed outside the pipeline, the external noise has a great influence on it, and the measurement is not accurate;

[0005] 2. This method is to judge whether the pipeline is leaking by measuring the acoustic wave signal of the pipeline wall, and the sound wave attenuates greatly when it is transmitted on the pipeline wall, so the detection distance of this method is relatively short
