Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and particularly relates to a pipeline diameter change detection device. Background Art

[0002] In the maintenance, fault diagnosis and optimal design of some pipeline systems, pipeline diameter change may cause problems such as unstable fluid flow, increased pressure loss, and flow rate change. Therefore, it is very important to regularly detect the diameter change part. Currently, commonly used methods include visual inspection and ultrasonic inspection by inspection robots.

[0003] For example, Chinese Patent Application CN108662352A discloses a diameter-changing pipeline detection robot, which includes a fixed seat, a first diameter-changing driving component, a second diameter-changing driving component, a controller and a detection device. The first diameter-changing driving component and the second diameter-changing driving component are respectively arranged on the opposite first side and second side of the fixed seat.
