In the anti-collision device, the anti-collision air bag 4 slides by utilizing the magnetic relation between the electromagnet 2 and the permanent magnet 11, so that the substrate 1 is made of a nonmetallic material, and the normal operation of the device is prevented from being influenced. The base plate 1 is provided with a plurality of electromagnets 2, the back of the anti-collision air bag 4 is fixed with a permanent magnet 11, and the anti-collision air bag 4 is fixed by attraction between the electromagnets 2 and the permanent magnet 11.

The number of the electromagnets 2 may be selected according to the specific situation, and at least three electromagnets are provided. The more the electromagnets 2 are arranged, the smaller the interval between the electromagnets 2 is, so that the positioning of the anti-collision air bags 4 is closer to the most suitable anti-collision position actually required by the ship, and the height of the anti-collision air bags 4 is more reasonable. Considering the flexible sliding of the crashproof gasbag 4 and saving space, a plurality of mounting grooves are arranged on the base plate 1, the electromagnet 2 is fixed in the mounting grooves, and the control switch of the electromagnet 2 is correspondingly arranged in the base plate 1. Because the working environment of the electromagnet 2 can be an underwater environment, the electromagnet 2 needs to be subjected to waterproof treatment.

At this time, the lowermost electromagnet 2 is adjusted to be in contact with the permanent magnet 11 on the rejection air bag 4, and at this time, the rejection air bag 4 will have a certain distance from the base plate 1, so that the rejection air bag 4 can move upward or downward. Meanwhile, the electromagnet 2 in the middle is adjusted to attract the permanent magnet 11 on the anti-collision air bag 4, so that the anti-collision air bag 4 moves to a height suitable for the draft of the ship.
In a state that the electromagnet 2 repels the permanent magnet 11, the sliding rail 12 on the anti-collision air bag 4 may be separated from the sliding groove 3, so that the anti-collision air bag 4 cannot be constrained to perform linear motion along the height direction of the substrate 1, and the substrate 1 is correspondingly provided with a limiting groove 13 extending along the parallel direction of the electromagnet 2, wherein the limiting groove 13 is communicated with the sliding groove 3.
