Description

Technical Field

[0001] This utility model belongs to the field of pipeline defect detection technology, and specifically relates to a pipeline defect detection mechanism. Background Technology

[0002] Pipeline inspection robots, also known as CCTV inspection robots, are devices that use machine vision and deep learning algorithms to detect defects on the inner walls of pipelines. The working principle of pipeline inspection robots is to use machine vision technology to acquire images of the inner walls of pipelines, and then use deep learning algorithms to process and analyze the images to determine the internal structure and defects of the pipeline.

[0003] Currently, common pipeline inspection robots mainly consist of a frame, a walking mechanism, a camera assembly, connecting pipelines, and a computing module. In use, they mainly acquire images of the inner wall of the pipeline through the camera assembly, and the camera assembly and the computing module are connected through the connecting pipelines.

[0004] As is well known, in practical applications, pipeline inspection robots move along with the connecting pipelines inside the pipelines to be inspected. However, most pipelines contain impurities such as dust, cobwebs, and sewage. As a result, after the pipeline inspection robot completes the inspection, the outer wall of the connecting pipeline will be affected by these impurities and become dirty. When this happens, it not only affects the cleanliness of the connecting pipeline and the smoothness of its storage, but also makes the connecting pipeline susceptible to corrosion and damage from these impurities. Consequently, the pipeline inspection robot has poor performance and a short service life.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a pipeline defect detection mechanism.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

During the winding process of the connecting pipeline 101, the fixed support rod 207 is locked and fixed by the connecting seat 206 and the fixed support 208, so that the scraper 203 is attached to the outside of the connecting pipeline 101. Thus, during the winding process of the connecting pipeline 101, the scraper 203 can scrape off the impurities adhering to the outside of the connecting pipeline 101.

[0050] Meanwhile, wiping liquid can be delivered into the liquid channel 204 through the liquid inlet 205. The wiping liquid can wet the wiping block 202 under the action of the through hole, thereby wiping and cleaning the outer surface of the connecting pipeline 101 through the mutual friction between the wiping block 202 and the connecting pipeline 101.

[0051] Subsequently, the connecting pipeline 101 can be dried and cleaned using the drying cotton layer 302. Furthermore, the connecting pipeline 101 can be moved and guided by the hanging ring 306 sliding along the guide limit rod 307. After cleaning, the connecting pipeline 101 can be wound up using the winding roller 103.
