[0002] Pipeline crack detection is a crucial step in ensuring the safe operation of pipeline systems. Endoscopic inspection is commonly used, which involves inserting a flexible or rigid pipe device equipped with a camera deep into the pipeline for observation. The endoscope can capture images of the inside of the pipeline, clearly showing defects such as corrosion, deposit accumulation, and cracks, providing accurate information for subsequent repair work.

[0003] Chinese patent discloses a pipe crack detection device for water conservancy projects (authorization announcement number CN221377912U). This patented technology adapts to different bending angles and directions within the pipe through the cooperation between the connector and the mounting sleeve, enabling the detection head to detect pipes with complex shapes and improving the adaptability of the detection head.
