The detection head 11 includes a camera, an ultrasonic sensor, and an eddy current sensor. Specifically, the camera is used for shooting and recording.

When the ultrasonic wave encounters defects such as pipe cracks, part of the ultrasonic wave will be reflected back. The sensor determines the location and size of the crack based on the time, intensity, and other information of the reflected wave. The eddy current sensor uses the principle of electromagnetic induction to detect pipe cracks. When the sensor is close to the pipe, eddy currents will be generated on the pipe surface.

The two clamping plates 95 moving toward each other can clamp the pushing end of the pusher 13 to facilitate the pushing work.

[0052] Embodiment 4:

[0053] Based on the third embodiment, Figure 7 and Figure 8 Specifically, the rotating mechanism 10 includes an adjusting frame 101 fixedly connected to the right side of the shell 1, a driving frame 102 is arranged inside the adjusting frame 101, and a reciprocating slide bar 106 is arranged at the driving end of the driving frame 102.
