The core working principle of the invention is that the displacement spring 4 and the parking spring 10 can cause the magnetic pole direction of each coil of spring to be the same due to the magnetic effect when being electrified, thereby contracting, and naturally extending when being powered off.

The following is a detailed working principle of the invention:

when the device is applied to dredging operation of a linear pipeline, the front parking spring, the rear parking spring and the displacement spring 4 are in a power-off state in an initial state, and the displacement spring 4 is in a tensioning state;

performing first-step displacement, sequentially powering off a front parking spring, powering on a rear parking spring and powering on a displacement spring 4, wherein the displacement spring 4 is changed into a compression state from a tension state, the front parking spring is freely tensioned, so that a friction pad 9 on a pressing plate 8 is tightly contacted with the inner wall of a pipeline, the front parking plate is a fixed point, and one end, connected with the displacement spring 4, of the rear parking plate moves towards the front parking plate;

performing the second displacement, sequentially powering off the rear parking spring, powering on the front parking spring and powering off the displacement spring 4, converting the displacement spring 4 from a compression state to a tension state, freely tensioning the rear parking spring to enable a friction pad 9 on a pressing plate 8 to be in close contact with the inner wall of the pipeline, setting the rear parking plate as a fixed point, and moving the end, connected with the displacement spring 4, of the front parking plate towards the position far away from the rear parking plate;

the first step displacement and the second step displacement are repeated in a circulating mode, so that the pipe can be moved in a stepping mode in a linear pipeline, the blockage breaking cone 2 at the front end of the front parking plate can break holes and disperse the sundries blocked in the pipeline, the pipe can be pushed gradually by continuing to move forwards, the dredging is realized, the pipe can work reversely, and the pipe can leave from the inlet of the pipeline.

In the present invention, the displacement spring 4 and the parking spring 10 are alternately powered on and off, which are controlled by the power management chip, and can be programmed by a simple digital circuit, and the other obstacle sensor can sense whether an obstacle exists to determine whether to continue traveling.

When the front parking plate and the rear parking plate are alternately fixed points, the load is required, and as the optimization of the invention, the elastic roller device can be arranged on the peripheral surface of the parking plate 1 to assist the support, thereby improving the working stability.
