Pipe leakage detecting device and detecting method

Abstract

The invention discloses a pipe leakage detecting device and detecting method. A surface acoustic wave detecting device of the detecting device is connected with a power generation device through a connector; the upper side of the surface acoustic wave detecting device is fixed on the inner wall of the upper side of a pipe to be detected; a surface acoustic wave sensor of the surface acoustic wavedetecting device is bonded with the inner wall of the upper side of the pipe to be detected; a signal input end of a controller is connected with an output end of the surface acoustic wave detecting device; an output end of an energy storer is connected with power supply ends of the surface acoustic wave detecting device and the controller; a magnet of the power generation device is opposite to amagnet of the surface acoustic wave detecting device; a rotatable metal track is coated on the outer surface of a shell of the power generation device; multiple metal wheel pieces are fixed on the rotatable metal track; and current generated by the metal wheel pieces is transmitted to the energy storer through the connector, and is converted through an internal power supply module for storage. Thedetecting device can realize self power generation and self power supply, achieves the use convenience, and solves the problem of difficult positioning of underground pipe permeation and rupture in the prior art.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a pipeline leakage detection device and detection method. Background technique [0002] The detection of pipeline penetration and fracture is currently a difficult point. Traditional inspections generally use manual inspection and dichotomous measurement. The current inspection method for pipelines is simple, and the inspection effect is poor, and the device needs to replace batteries and other equipment, which cannot run for a long time, and the cost of replacing batteries is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a pipeline leakage detection device and detection method, which realizes a long-term unattended operation mode through self-power supply, so as to effectively solve the power supply problem and improve detection accuracy at the same time. [0004] To achieve the above object, the present invention prov...
