This application discloses a magnetically coupled collaborative pipeline inspection
robot system, relating to the field of pipeline inspection equipment technology. The
system includes an internal
robot and an external
robot. The internal robot is located inside the pipeline, while the external robot is located outside the pipeline at a corresponding position, and the two are magnetically coupled together. During the inspection process,
angular velocity, acceleration, and distance to the pipeline wall are collected to control the movement of the external robot. A camera on the internal robot captures images of the pipeline interior, which are analyzed by a vision processor to determine defects inside the pipeline. By employing a magnetically coupled dual-drive
system and a
Halbach array design, this application achieves contactless
power transmission between the external and internal robots, eliminating the risks of entanglement, wear, and leakage explosion that may occur in high-risk environments such as oil and gas and power plants caused by cable-driven power supply structures, thus improving the safety of inspection operations and the stability of system operation.
