Abstract

The invention discloses a novel magnetic flux leakage detection device in a pipeline. A main device body is provided with a multi-pipe-diameter magnetic flux leakage detection device and a plurality of power mechanisms. The multi-pipe-diameter magnetic flux leakage detection device is formed by a plurality of groups of multi-pipe-diameter magnetic flux leakage detection mechanisms. A rotating partrotates to drive a rotating shaft to rotate; and the rotating shaft rotates to drive the plurality of groups of multi-pipe-diameter magnetic flux leakage detection mechanisms connected to the rotating shaft to make rotation. A ball connecting rod I and a detection connecting rod I are fixedly connected with the rotating shaft and rotate with rotation of the rotating shaft; and a clamping buckle moves along a moving slot, so that the measurement pipe diameter of the multi-pipe-diameter magnetic flux leakage detection device is adjusted. Movement is realized by using a moving ball arranged on aball connecting rod II and detection is performed by using a magnetic flux leakage detector arranged on a detection connecting rod II. Power mechanisms drive rotating pieces connected with rotating parts of the power mechanisms to rotate under rotation of power motors. The device moves forward when the power motors rotate forwardly and the device moves backwardly when the power motors rotate reversely.

Description

technical field [0001] The invention relates to the field of electromagnetic detection, in particular to a novel magnetic leakage detection device in pipelines. Background technique [0002] Magnetic flux leakage detection in pipelines is currently a relatively mature and widely used detection technology in pipelines. Magnetic flux leakage detection technology can detect metal loss defects such as corrosion and mechanical damage on the inner and outer walls of pipelines, and has low requirements for the cleanliness of the pipelines to be tested. It is also used for oil and gas pipelines. Through online detection, defects can be identified, located and quantitatively counted, which is an important means to guide reasonable maintenance of pipelines and carry out pipeline integrity management. [0003] However, the current magnetic flux leakage detection devices in pipelines can only perform magnetic flux leakage detection for pipelines of one diameter, either larger diameter ...
