Description

Technical field [0001] The present invention relates to the field of underwater non-destructive flaw detection, in particular, underwater non-destructive flawless equipment and treatment methods based on visual and magnetic powder. Background technique [0002] With the continuous development of marine resources, there are more and more at sea mobile devices and fixed devices, and the water pipeline also presents burst growth. When the submarine pipeline is insufficient, the seabed wave flow repeatedly Fatigue damage occurs at the pipeline connection; the air acala or the fall against the ship can cause pipeline damage, which will cause the pipeline to break; if the pipeline is laid in the sand, there is a large rheological unstable sea bed, sometimes It will occur due to the collapse of the seafris, slide, and erosion, and the destruction is damaged. Therefore, the seabed pipeline needs regular inspection. [0003] Traditional pipeline underwater non-destructive flaw detection t...

Problems solved by technology

[0003] The traditional underwater non-destructive flaw detection technology of pipelines mainly relies on artificial submerged flaw detection, and the operators need to stay on the seabed for a long time to complete the inspection operations. The research on flaw detectors mostly involves the process of autonomous flaw detection of underwater flaw detectors and image information transmission. Image analysis still needs to be done manually, and a new solution is urgently needed
