Abstract

The invention discloses a pipeline detection device, which belongs to the technical field of pipeline detection. By installing an air cylinder at one end of the frame and a power unit on the air cylinder, under the control of the controller, the power supply supplies power to the power unit, so that the propeller in the power unit can obtain the propulsion exerted by the medium by rotating in the medium Force to promote the movement of the entire pipeline inspection device. Therefore, the device can travel in the pipeline only relying on its own power unit to provide power without the use of high-pressure medium, so as to realize the effective detection of defects on the pipeline wall.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a pipeline detection device. Background technique [0002] Before the long-distance oil and gas pipeline is put into production and during use, it is necessary to regularly detect the defects in the pipeline. Usually, the defects on the pipeline wall are detected by putting a pipeline detection device into the pipeline. [0003] At present, the commonly used pipeline detection device includes a detection unit and a power supply unit. Flow, the flowing medium exerts pressure along the flow direction on the pipeline detection device, and the pressure can push the pipeline detection device to move so that the detection unit can perform detection. [0004] Before the pipeline is put into production or in other special production processes, when there is no high-pressure medium in the pipeline, the pipeline detection device cannot move in the pipeline, so it cannot effecti...
