TRACKING AND MONITORING DEVICE Russian patent published in 2021 - IPC G01N21/954 

FIELD: remote visual monitoring.

SUBSTANCE: invention relates to tracking and monitoring devices designed for remote visual monitoring and video recording of the state of the internal surfaces of pipelines under pressure, as well as for monitoring the processes of mechanical processing in them. The device includes an attachment unit to the pipeline, made in the form of a fitting; a shut-off valve unit, made in the form of a ball valve, rigidly and hermetically attached to the second end of the fitting by means of a threaded connection; the assembly for drilling a through hole in the pipeline wall at the point where the attachment unit joins the pipeline through the shut-off valve assembly and the attachment unit to the pipeline; the access unit to the pipeline, made in the form of a base with a through round hole, having the shape of a plate, and also rigidly and hermetically attached to it from the bottom of the adapter, having the shape of a cylinder covering the hole in the base; the rod, made in the form of a hollow tube, placed in the access unit to the pipeline; a sealing unit made in the form of a cuff inserted into a groove in the lower part of the base around the through hole; a pressure relief unit; an articulation unit; a chamber; a drive unit; a light source; an information output unit; an electrical cable connecting the camera to the image output unit, laid through the inner cavity of the stem tube. The device provides high positioning accuracy and stabilization of the chamber position in the pipeline, as well as compensation for the ejection effect of the in-line pressure.

EFFECT: high positioning accuracy and stabilization of the chamber position in the pipeline.
