Description

The inspection of drainage pipes and rainwater pipes is related to whether the sewage is discharged smoothly. Pipe rupture will cause safety problems such as road collapse.

[0003] The existing patent (CN218121899U) discloses an oilfield pipeline defect detection device, which drives the detector and the detection block to rotate in the detection tube through a rotating component, and cooperates with the moving mechanism to detect the entire pipeline, thereby increasing the detection range and avoiding the staff from easily missing the detection of part of the pipeline when conducting inspection with the handheld detector, which poses a safety hazard. The oilfield pipeline defect detection device drives the mounting block to move on two guide shafts through a driving component, so that the detection tube moves on the pipeline body, and cooperates with the detection mechanism to detect the outer surface of the pipeline body, thereby avoiding the staff from conducting inspection of the pipeline with the handheld detector.

[0004] However, the above technical solution has certain defects. Since the size of the annular plate cannot be adjusted, it cannot adapt to pipes of different specifications during use and cannot detect pipes of different specifications.
