Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe defect detection equipment, in particular to a drainage pipe internal defect detection equipment. Background Art

[0002] With the acceleration of urbanization, drainage pipes, as an important part of urban infrastructure, are receiving more and more attention for their safe operation and maintenance. Since drainage pipes are in harsh environments such as moisture and corrosion for a long time, they are prone to defects such as cracks and breakage. At this time, the performance requirements for the produced drainage pipes are relatively high. In order to ensure that the produced drainage pipes meet the planning requirements, it is usually necessary to detect whether there are defects inside the produced drainage pipes to ensure that there are no defects inside the drainage pipes and to achieve the effect of extending the service life. When performing defect detection operations, corresponding defect detection equipment is usually required. There are many types of defect detection equipment on the market. Common defect detection equipment includes flaw detectors. Flaw detectors are engineering equipment used to detect internal defects of machined parts.

[0003] Flaw detectors typically consist of a main unit, cables, and probes. However, these instruments lack mounting or fixing components for the probes, making them difficult to hang or attach directly to pipes for inspection. Holding the probe for extended periods of time prevents hands from being free for other tasks and can easily cause the probe to fall off the hand or pipe, causing inconvenience. Therefore, we propose a device for detecting internal defects in drainage pipes. Utility Model Content

[0008] Preferably, the height of the penetration gap is greater than the inner diameter of the cross-sectional circle of the arc-shaped sleeve, which is used for the penetration and withdrawal operations of the pipeline.

[0009] Preferably, the bottom end of the detection probe passes through the arc-shaped plate of the arc-shaped sleeve, and is used to perform defect detection operations on the pipeline in the arc-shaped sleeve.
