Three-dimensional ultrasonic detection system for pipeline defect detection

Abstract

The invention discloses a three-dimensional ultrasonic detection system for pipeline defect detection, the three-dimensional ultrasonic detection system comprises a detection end and a control end, the detection end comprises a moving plate, a plurality of supporting plates are fixedly connected to the bottom side wall of the moving plate, a rotating rod is rotatably connected to every two moving plates, moving wheels are fixedly connected to the two ends of each rotating rod, the bottom side wall of the moving plate is provided with a moving device, the side wall of the moving plate is fixedly connected with a camera, the upper side wall of the moving plate is provided with a detection device, and the upper side wall of the moving plate is fixedly connected with a first power supply module and a first wireless transceiver module. A worker only needs to operate the display module, the whole pipeline can be sequentially detected, the labor intensity is greatly reduced, the detection efficiency is high, meanwhile, the whole pipeline can be visually detected from the interior of the pipeline, and the detection result error is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a three-dimensional ultrasonic detection system for pipeline defect detection. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly used in water supply, drainage, heat supply, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering and various industrial installations. During production or after a period of use, pipelines need to be The pipeline is inspected. [0003] In the prior art, because the interior of the pipeline is relatively narro...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, because the inside of the pipeline is relatively narrow, the outside of the pipeline is generally detected by hand-held ultrasonic detectors to detect whether there is corrosion or cracks in the pipeline, and it is impossible to visually detect the whole pipeline from the inside of the pipeline, so that the detection results are limited. At the same time, the overall length of the pipeline is generally too long, and manual inspection along the pipeline is labor-intensive and inefficient.
