Three-dimensional magnetic flux leakage imaging detector in multi-section combined pipeline

Abstract

The invention discloses a three-dimensional magnetic flux leakage imaging detector in a multi-section combined type in-pipeline. The detector comprises a driving section assembly, a detection section assembly, an I / O / DO detection section assembly and an odometer wheel assembly which are sequentially connected in the advancing direction of the detector, and the second end of the driving section assembly and the second end of the detection section assembly are each hinged to a coupling assembly. The second end of the driving joint assembly is hinged to the first end of the detection joint assembly through the coupling assembly, the second end of the detection joint assembly is hinged to the first end of the IO / DO detection joint assembly through the coupling assembly, and the second end of the IO / DO detection joint assembly is hinged to the first end of the odometer wheel assembly. The driving joint assembly, the detection joint assembly and the IO / DO detection joint assembly are arranged and connected through the coupling assemblies, detection in a bent pipeline is facilitated, and the mileage wheel assembly is matched, so that the advancing mileage can be recorded, and mileage data are provided for analyzing pipeline damage points.

Description

technical field [0001] The invention relates to the technical field of three-dimensional magnetic flux leakage imaging detection in pipelines. Specifically, it is a three-dimensional magnetic leakage imaging detector in a multi-section combined pipeline. Background technique [0002] The magnetic flux leakage detection in the pipeline is a means of detecting the pipe wall by using the magnetic flux leakage detection technology. The magnetic flux leakage detection in the pipeline generally uses the fluid in the pipeline to push the detector forward, but in actual use, the fluid in the pipeline may exist The flow rate is small, which leads to slow propulsion speed, and even when the flow rate is seriously insufficient, the detector is stuck in the pipeline, which brings great inconvenience to use; and most of the existing detectors use a battery compartment to provide power. A problem with a single power supply will directly cause the detector to fail to work normally. Cont...
