Problems solved by technology

[0002] In the field of existing fluid logistics pipeline detection, the detection method of pipeline damage is mainly current gradient detection, which needs to be measured manually or mechanically along the pipeline. There is no reliable dynamic real-time monitoring method, especially when it is buried tens of meters deep underground. , or even hundreds of meters of pipeline

Embodiment Construction

[0016] Such as figure 1 As shown, a pipeline damage detection device includes an outer wall tube 1 and an inner wall tube 2, the inner wall tube 2 is located in the outer wall tube 1, and the middle area formed between the outer wall tube 1 and the inner wall tube 2 is filled with a filling liquid 3, filled The liquid 3 is a liquid or paste-like substance; several pressure sensors 4 are arranged in the middle area, both ends of the middle area are closed, and the pressure sensors 4 are connected to an external monitoring system 5 .

[0017] A method for detecting damage to a delivery pipeline, using the above-mentioned detection device, and including the following steps:

[0018] (1) Static detection

[0019] (1) When the inner wall pipe 2 is empty, use the external monitoring system 5 to read the monitoring value P0 of the nth pressure sensor;

[0020] (2) Fill the inner tube 2 with liquid or pasty substance, and close both ends of the inner tube 2, apply a certain pressure...

Abstract

The invention provides a device and method for detecting breakage of a delivery pipe. The device comprises an outer wall pipe and an inner wall pipe, wherein the inner wall pipe is located in the outer wall pipe, a middle area formed between the outer wall pipe and the inner wall pipe is filled with filling liquid, a plurality of pressure sensors are further arranged in the middle area, the two ends of the middle area are closed, and the pressure sensors are connected with an external monitoring system. The method includes the following operation steps: (1) reading a monitoring value P0 of the nth pressure sensor in the state that the inner wall pipe is empty; (2) filling the inner wall pipe with liquid or paste materials, closing the two ends of the inner wall pipe, exerting a certain pressure P1 on the liquid or the paste materials in the inner wall pipe, and reading a monitoring value P2 of the nth pressure sensor at the moment; (3) comparing the value P0 with the value P2, wherein if the P2 is greatly changed relative to the P0, it is indicated that the inner wall pipe is broken, and if the P2 is basically not changed relative to the P0, it is indicated that the inner wall pipe is not broken.

Description

technical field [0001] The invention belongs to the field of fluid material conveying pipeline detection, and relates to a conveying pipeline damage detection device and method. Background technique [0002] In the field of existing fluid logistics pipeline detection, the detection method of pipeline damage is mainly current gradient detection, which needs to be measured manually or mechanically along the pipeline. There is no reliable dynamic real-time monitoring method, especially when it is buried tens of meters deep underground. , or even hundreds of meters of pipeline. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, and provide a damage detection device for a conveying pipeline with a simple structure and reliable operation. [0004] Another object of the present invention is to provide a simple and practicable method for detecting the damage of the conveying pipeline. [0005] For this reaso...
