Technical Field

[0002] After the production of anti-corrosion pipelines, it is usually necessary to use anti-corrosion layer electric spark detection equipment to test the integrity of the anti-corrosion material coated on the outside of the anti-corrosion pipeline. Through this test, defects in the anti-corrosion material on the outside of the pipeline can be discovered in time and dealt with in time, thereby ensuring the long-term and reliable use of the pipeline.

[0003] At present, when using anti-corrosion layer electric spark detection equipment to detect the anti-corrosion material on the outside of the pipeline, it is usually necessary to manually use a straight or arc-shaped handheld brush to detect the outside of the anti-corrosion material layer of the pipeline. The detection length between the straight-line brush and the pipeline axis is short, and the handheld brush needs to be moved back and forth around the pipeline for detection, which is inconvenient to use; the arc-shaped brush can have a larger coverage area in the axial direction of the pipeline than the straight-line brush, and there is no need to reciprocate around the pipeline for detection, but the detection personnel need to move back and forth along the axial direction of the pipeline to be tested for detection, and the detection efficiency is still not high.

[0004] Therefore, it is necessary to design an anti-corrosion material layer integrity detection device that improves the circumferential coverage of the pipeline and improves the detection efficiency to solve the current technical problems. Summary of the invention
