A Novel Pipeline Continuity Checking Method

Abstract

The invention discloses a novel pipeline connectivity inspection method, which comprises the following steps: classifying pipeline systems; connecting a detection device to the pipeline system; In the system, one end is connected with the transmitter signal, the other end is connected with the receiver signal, the transmitter and the receiver are respectively connected with the display control computer; the transmitter converts the transmission command into an electrical signal, and the signal transmission component converts the electrical signal into an acoustic signal It is transmitted in the pipeline system; the acoustic signal is converted into an electrical signal by the signal transmission component of the acoustic signal transmission terminal, the receiver collects and receives the electrical signal and processes it, and the display and control computer calculates and displays the information fed back by the receiver, and judges whether the pipeline is connected or not. No communication, the present invention has high operation efficiency, no need for personnel to enter the pipeline for inspection, safe operation, low operation cost, no need for personnel and equipment to enter the inside of the pipeline, and a wide range of adaptability.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a novel pipeline connectivity inspection method. Background technique [0002] In the process of urban infrastructure construction, a large number of pipelines are laid underground, such as power supply pipelines, water supply pipelines, sewage pipelines and communication pipelines. During use, with the accumulation of time, there are hidden dangers of blockage and collapse due to pipeline damage. In order to eliminate hidden dangers in time or locate the blocked part of the pipeline, it is necessary to check the connectivity of the pipeline. [0003] The traditional pipeline connectivity inspection methods mainly include manual inspection, pipeline CCTV inspection, pipeline sonar detector and pipeline periscope method. The manual inspection method has disadvantages such as high labor intensity, low operation efficiency, harsh operating environment and hidden dangers ...

AI Technical Summary

Problems solved by technology

The manual inspection method has disadvantages such as high labor intensity, low operating efficiency, harsh operating environment, and potential safety hazards for personnel, especially when inspecting sewage pipes, there are high potential safety hazards for personnel

Due to their short working distance, pipeline closed-circuit television and pipeline sonar detectors must be carried on inspection carriers, such as personnel or inspection robots, which have the same disadvantages as manual inspection methods

At the same time, there are disadvantages such as high cost, limited use environment and low operation efficiency when mounted on inspection robots.

The pipeline periscope method has the disadvantage of short working distance, and is only suitable for checking the area near the inspection shaft or observation hole
