[0041] The working principle of the above embodiment is as follows:

[0042] (1) When repairing the underground pipe network, the repairing device can be moved to the position to be repaired in the pipe through the second roller 67. In order to facilitate the searching of the position to be repaired in the pipe by the camera 75, the output shaft of the second motor 72 rotates to drive the rotation of the spur gear 73, and the rotation of the spur gear 73 drives the rotation of the rotating disc 74 meshed with the surface of the spur gear 73.

[0043] (2) When the bottom plate 1 needs to pass through the protrusion of the pipe connection, the two electric push rods 2 can be started synchronously.

When the first rollers 63 on the front and rear sides are attached to the inner cavity of the pipe, the electric telescopic rods 61 can be stopped, and then the motor 64 can be started. The rotation of the output shaft of the motor 64 drives the rotation of the screw rod 65, and the rotation of the screw rod 65 drives the movement of the movable plate 66 meshed with the surface of the screw rod 65. At this time, the movable plate 66 moves upward under the limitation of the limiting plate and the limiting strip, thereby driving the upward movement of the four second rollers 67. Then, the repairing device is driven to pass through the protrusion of the pipe connection by the four first rollers 63.
