Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pipeline ultrasonic detector. Background Art

[0002] In industries like petroleum, chemical processing, water treatment, and energy transmission, pipelines are critical infrastructure. Their wall thickness and internal structural integrity are directly related to the safe operation and production efficiency of the systems. Traditionally, pipe wall thickness testing has mostly relied on handheld ultrasonic thickness gauges. While this method offers certain accuracy and flexibility, it suffers from numerous practical limitations.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following drawbacks often exist: First, traditional handheld ultrasonic thickness gauges require the operator to personally place the probe tightly against the outer wall of the pipe to obtain accurate measurement data. This operation is not only labor-intensive and requires the operator to maintain concentration and a stable hand posture for a long time, but is also prone to measurement errors due to human factors (such as probe placement angle and uneven force). Frequent changes in monitoring points and testing positions undoubtedly increase the operator's burden and reduce testing efficiency.

[0004] Secondly, due to the circular structure of the pipeline itself, its surface curvature makes it difficult to directly touch the side away from the operator (i.e., the back or bottom of the pipeline), which creates a blind spot for detection. To compensate for this defect, operators usually need to detour to the corresponding side of the pipeline for inspection, which not only prolongs the inspection cycle but also increases the difficulty of the work. Utility Model Content
