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...
