In-pipeline self-adaptive movable detection device

Abstract

The invention belongs to the field of mechanical automation engineering and particularly relates to an in-pipeline self-adaptive movable detection device. The in-pipeline self-adaptive movable detection device comprises a movable mechanism, a video collection mechanism and a signal output mechanism, and the video collection mechanism and the signal output mechanism are located on the front side and the rear side of the movable mechanism correspondingly. The movable mechanism comprises a split-face machine body, tightening mechanisms and driving mechanisms. The end face of the split-face machine body is square and is provided with four datum planes, and each datum plane is connected with the corresponding driving mechanism through the corresponding tightening mechanism. The driving mechanisms abut against the inner walls of pipelines of different inner diameters through stretching and contracting of the tightening mechanisms so as to adapt to the pipelines of the different inner diameters. All the driving mechanisms drive the detection device to move in the pipelines of the different inner diameters. The two ends of the split-face machine body are in seal connection with the video collection mechanism and the signal output mechanism correspondingly. The in-pipeline self-adaptive movable detection device is simple and reliable in structure and can monitor and measure the environments in straight pipes, bent pipes and U-shaped pipes in real time.

Description

technical field [0001] The invention belongs to the field of mechanical automation engineering, in particular to an adaptive movement detection device in a pipeline. Background technique [0002] Urban pipe networks, industrial pipes, and pipes, as the main transportation facilities for people's daily raw materials, are widely used because of their convenience and economy. In the past few decades, our country has built a large number of underground pipeline network systems to transport natural gas, oil and various civil liquid substances. Ensuring the safety and effectiveness of these pipeline systems is crucial to our country's energy security. However, as the service life increases, the pipeline will inevitably age, crack, corrode or be damaged by external construction. At the same time, the newly laid pipeline also has problems such as weak welding and missing welding of the weld; Once an accident occurs, it will bring huge losses to the country and the environment, so i...
