Pipeline internal inspection device

Abstract

The invention provides a pipeline internal inspection device. A detection assembly and a driving umbrella are fixedly connected to a connection pole, after the driving umbrella is opened, under the pushing of water flow, the driving umbrella drives the detection assembly and the connection pole move along the water flow, a cable assembly connects the detection assembly and a monitoring platform, the cable assembly reels and unreels a cable when the detection assembly moves along the water flow, and the detection assembly acquires the image and sound signals in the pipeline and sends the image and sound signals to the monitoring platform. The pipeline internal inspection device provided judges the faults through the combination of the video and audio data and has high accuracy; and the pipeline internal inspection device can rapidly find and position pipeline leakage or other faults, and can timely identify pipeline inner wall scaling and corrosion or other hidden troubles; and by means of the medium flow in the pipeline, a probe is driven by the umbrella device to move in the pipeline without additional energy, so that the design of a probe moving device is simplified.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, in particular to a pipeline endoscopic detection device. Background technique [0002] Municipal pipelines such as water supply, drainage, and gas pipelines are the blood of modern cities and occupy an irreplaceable position in people's daily life and urban development. With the acceleration of urbanization in my country, the scale of municipal pipelines continues to expand. Since urban water supply, drainage, gas and other pipelines are mostly buried underground, human eyes cannot see through the use of the pipelines, which brings great difficulties to pipeline investigations, and it is also difficult to find and locate problems such as leaks and ruptures in pipelines. In addition, even if the pipeline is dug, the corrosion and scaling on the inner wall of the pipeline cannot be identified only from the outside. [0003] This patent will build a set of mobile pipeline endoscopic det...

Problems solved by technology

Since most of the urban water supply, drainage, gas and other pipelines are buried underground, the human eye cannot see through the use of the pipeline, which brings great difficulties to the pipeline investigation. Once the pipeline leaks, ruptures and other problems, it is also difficult to be found and located.

In addition, even if the pipeline is dug, the corrosion and scaling on the inner wall of the pipeline cannot be identified only from the outside
