Each second wheel works with a second drive motor to achieve four-wheel drive, which improves adaptability to pipelines, enhances passability, provides stronger power (i.e., greater thrust), and better drives the data transmission line and propels the first trolley.

[0012] Furthermore, the second vehicle body is equipped with a second control board and a second battery, and the second battery and the second drive mechanism are both electrically connected to the second control board.

[0013] In some embodiments of this application, the probe, the first trolley, and the second trolley are arranged sequentially at intervals. The probe is placed outside the trolley to reduce obstruction by the trolley and to ensure comprehensive pipeline inspection.

[0014] In some embodiments of this application, both the first and second trolleys are provided with wire buckles, and data transmission lines are threaded through the wire buckles; the data transmission lines are optical fibers. Attached Figure Description
