Description

Technical Field

[0001] The utility model relates to the field of pipeline detection, in particular to a water conservancy project pipeline crack detection device. Background Art

[0002] Water conservancy project quality inspection can be referred to as quality inspection. It refers to the activities carried out by water conservancy project quality inspection units to inspect, measure, test or measure water conservancy project entities and raw materials, intermediate products, metal structures and electromechanical equipment used in water conservancy projects, and compare the results with relevant standards and requirements to determine whether the project quality is qualified. It is called water conservancy project pipeline inspection.

[0003] For example, the patent document with the announcement number CN221377912U discloses a water conservancy project pipeline crack detection device. The utility model provides a water conservancy project pipeline crack detection device that can adapt to pipelines of different specifications. A water conservancy project pipeline crack detection device includes a holding rod, a mounting sleeve rod, a connector and a mounting frame, etc. The left part of the holding rod is rotatably connected to the mounting sleeve rod made of elastic material, and the mounting sleeve rod is rotatably connected to a plurality of snap-shaped spliced ​​connectors. The left and right adjacent connectors are rotatably connected, and the rightmost connector is connected to the left side of the holding rod. The utility model adapts to different bending angles and bending directions in the pipeline through the cooperation between the connector and the mounting sleeve rod, thereby enabling the detection head to detect pipelines of complex shapes, thereby improving the adaptability of the detection head. In the inspection of cracks in water conservancy project pipelines, since the diameters of the pipelines to be inspected are different and the bending methods of the pipelines are diverse, the crack detection device needs to be able to adapt to pipelines of different diameters and pass through various bends. On this basis, it can be expected that when the cracks are located in the inclined or curved part of the pipeline, there is a possibility of slippage during the crack detection process of the device, resulting in detection distortion. Therefore, the detection device also needs to have good anti-slip capabilities. Utility Model Content

The electromagnet 404 is energized to generate a magnetic force to drive the L-shaped connecting rod 402 and the middle connecting rod 403 close to the inner wall of the pipeline, so that the moving belt 406 can be closely attached to the inner wall of the pipeline. At the same time, the setting of the electromagnet 404 can also increase the pressure on the moving belt 406, thereby increasing the friction. In the process of the electromagnet 404 generating magnetic force, the principle of like poles repel each other is used to increase the distance between the rotating wheels 405, so that the moving belt 406 can be tensioned to improve the anti-slip ability.
