Novel pipeline connectivity inspection method

Abstract

The invention discloses a novel pipeline connectivity inspection method. The method comprises the following steps: classifying a pipeline system; connecting a detection device with the pipeline system, wherein the detection device comprises a display control computer, a transmitter, a receiver and a signal transmission assembly, the signal transmission assembly is placed in the pipeline system, one end of the signal transmission assembly is in signal connection with the transmitter, the other end of the signal transmission assembly is in signal connection with the receiver, and the transmitter and the receiver are connected with the display control computer; converting transmitting commands into electric signals through the transmitter, converting the electric signals into sound signals and transmitting the sound signals in the pipeline system through the signal transmission assembly; converting the sound signals into electric signals at a sound signal transmission terminal through the signal transmission assembly; collecting, receiving and processing the electric signals through the receiver; and calculating and displaying information fed back by the receiver, and judging whether the pipeline is connected or disconnected through the display control computer. The novel pipeline connectivity inspection method is high in operation efficiency; workers do not need to enter the pipeline for inspection; the operation is safe; the operation cost is low; the workers and equipment do not need to enter the pipeline; and the application range is wide.

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 landslide due to pipeline damage. In order to eliminate hidden dangers in time or locate the blocked parts of the pipeline, it is necessary to check the connectivity of the pipeline. [0003] Traditional pipeline connectivity inspection methods mainly include manual inspection, pipeline closed-circuit television detection, pipeline sonar detector and pipeline periscope methods, etc. The manual inspection method has disadvantages such as high labor intensity, low operating efficiency, harsh operating environ...

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
