Description

Technical Field

[0001] The utility model relates to a pressure pipeline self-propelled detection device, in particular to a pressure pipeline self-propelled detection device, belonging to the technical field of pressure pipeline detection. Background Art

[0002] Pressure pipelines refer to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. Pressure pipelines are part of pipelines, and pipelines are used to transport, distribute, mix, separate, discharge, measure, control and stop the flow of fluids. As the service time increases, the pipelines will be affected by corrosion and other factors, and damage such as perforation, cracks, and local thinning of the pipeline wall will occur. Therefore, pressure pipelines need to be inspected regularly.

[0003] The pressure pipeline infrared detection device disclosed in the Chinese patent application publication specification CN219657541U can flexibly adjust the distance between the infrared detection probe and the surface of the pipeline to be detected. Multiple probes can simultaneously detect multiple parts of the outer surface of the pipeline, thereby having good detection stability and high detection efficiency.

[0004] However, during the implementation of the technical solution of the above patent, the debris adhered to the surface of the pressure pipe may affect the detection results. After long-term use, some debris such as soil may adhere to the surface of the pressure pipe. When the pressure pipe is inspected with an infrared probe, these debris will affect the reflection of infrared rays, which may lead to inaccurate detection results. Utility Model Content
