As a preferable technical scheme of the embodiment, a method for using an auxiliary device for autonomous collision avoidance of a ship comprises the following steps:
1. after one side of the hull 1 is impacted, the impacted side plate 31 approaches to the side of the hull 1, the first sliding block 33 adjacent to the side plate slides in the first sliding groove 32 in the process, the second spring 34 is stressed to shorten and store elastic potential energy, when the impact force on the hull 1 disappears, the second spring 34 in the first sliding groove 32 pushes the first sliding block 33 to move, and the side plate 31 is forced to move away from the hull 1 to the original distance again;
2. when the ship body 1 collides with the side edges of other ships in the process of meeting the ships, the transverse collision prevention mechanism 3 can buffer the side edges of the ship body 1, and simultaneously, a plurality of groups of first synchronous belt wheels 41 on the outer side of the side plate 31 roll on the side edges of other ships so as to replace the direct friction damage of the side edges between the two ships;
3. if the hull 1 needs to be assisted in decelerating, the electric push rod 453 is controlled to extend through the control panel 11, the whole square frame 22 is driven to move towards one end of the hull 1 by being matched with the L-shaped mounting seat 23, and in the process, the fourth sliding block 452 slides in the fourth sliding groove 451 until the second sliding block 442 and the third sliding block 445 are clamped by the synchronous belt 46 between the second sliding block 442 and the third sliding block 445;

5. and then the electric push rod 453 is controlled to be shortened, the second slide block 442 is separated from the third slide block 445, so that the elastic potential energy of the third spring 443 and the fourth spring 446 can be released, and the navigational speed of the ship body 1 can be quickly reduced to be within a safe range through repeated operations.
In the embodiment 1, as shown in fig. 1-11, the bottom of the outer sides of the two sets of side plates 31 is provided with the strip-shaped foam floating plates with the same length as the side plates 31, when the side edge of the hull 1 collides with another ship directly, the side plate 31 on the side where the hull 1 collides approaches the hull 1, and the side plate 31 on the other side of the hull 1 is forced to push the set of side plates 31 away from the hull 1 by the pushing force of the second spring 34 to the first sliding block 33, and the interval between the two sets of side plates 31 can be kept unchanged all the time by the cooperation of the synchronous belt 46 and the first synchronous belt wheel 41, after the side plate 31 on the other side of the hull 1 is far away from the hull 1, the strip-shaped foam floating plates on the bottom of the side plates 31 are also far away from the hull 1, if the hull 1 is impacted with large force, when the hull 1 itself tilts, the strip-shaped foam floating plates on the outer sides of the set of the side plates 31 can provide buoyancy support for the hull 1 immediately after contacting the water surface, and the condition that the hull 1 is turned side can be effectively avoided.
