Pipeline sealing performance location monitoring system and pipeline sealing performance detecting method

Abstract

A pipeline sealing performance location monitoring system comprises a leakage detecting vehicle, a location vehicle and an intelligent terminal. The leakage detecting vehicle comprises a first vehicle body, and an air pressure sensor and a first communication device are arranged on the first vehicle body. The location vehicle comprises a second vehicle body. A driving device, a second communication device, a processor, a speed detector, a crystal oscillation unit and a ranging assembly are arranged on the second vehicle body. The pipeline sealing performance detecting method includes the following steps: 1 pressurizing the inside of a pipeline and arranging the pipeline sealing performance location monitoring system into the pipeline; 2 conducting forwarding detection, conducting repeated detection if air pressure changes and continuing conducting forwarding detection if the air pressure change is small. Devices adopted by the pipeline sealing performance location monitoring system are high in cost performance and accurate in location, a test result can be processed and displayed in real time, and the shortcomings of the existing various pipeline breaking detection methods are overcome. By means of the pipeline sealing performance detecting method, a double-vehicle detecting mode is adopted to enable the location to be direct and accurate, and the pipeline detection efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of pipeline detection equipment, and more specifically relates to a pipeline tightness positioning monitoring system and a pipeline tightness detection method. Background technique [0002] Pipeline transportation, as the simplest and direct way of fluid transmission, has been widely used by human beings. Especially in recent decades, due to the characteristics of low cost of pipeline transportation, simple maintenance, high safety, and stable supply, its application scope has been continuously expanded, including oil, natural gas, tap water, and even sewage treatment. However, if you want to use pipelines for fluid transmission normally, you must have highly reliable and highly sealed pipelines. However, during the production process of the pipeline, there may be poor airtightness due to process problems; especially in today's production applications, long-distance transmission pipelines need to b...

Problems solved by technology

This method is relatively mature and simple, but since the climbing machine needs to use liquid flow to push it forward, it is not suitable for pipelines with many elbows, and the climbing machine generally records the data and judges the leakage after it flows out of the pipeline, so It is difficult to quickly judge the leakage, and at the same time, affected by the fluid velocity, it is difficult for the intelligent crawler to accurately locate the leakage point
