After long-term use, dirt or damage will occur. When the oil pipeline is used subsequently, it is necessary to use a flaw detection device to inspect the oil pipeline to ensure the stable effect of the subsequent use of the oil pipeline to transport crude oil.

[0003] When the oil pipe is used subsequently, a flaw detection device is needed. Among them, the "a waste oil pipe wall flaw detection device" disclosed by the application number "CN219245458U" has solved the various disadvantages that before the flaw detection operation, the oil pipe to be tested needs to be lifted onto the equipment and connected to the equipment before the detection operation can be carried out, the use is not convenient, and the adjustment of the detection position is not flexible enough.

[0004] However, there are still many defects in the actual use of flaw detection devices with similar structures, such as: the device does not have the function of self-cleaning, the oil stains inside the oil pipe easily affect the clear flaw detection effect of the device, reducing the intelligent effect of using the device, and at the same time, it does not have the function of flaw detection of different pipe fittings and oil pipes, and the device is easily limited by the diameter of the oil pipe, which reduces the scope of application of the device. Therefore, it is necessary to design a flaw detection device for repairing the oil pipe wall. Utility Model Content
