[0039] The present invention fixes the buffer pad 201 in the array to the position on the outer surface of the pier body 1 that needs to be protected;

[0040] After the array inner buffer pad 201 is fixedly connected to the outer surface of the pier body 1, a spiral spring piece 202 is connected between the array outer buffer pad 203 and the inner buffer pad 201, and the outer fixing ring 204 is fixedly connected to the outer end of the array outer buffer pad 203;

[0041] When a ship collides with the present invention, since the array of main anti-collision blocks 306 are evenly and circumferentially arranged on the outer surface of the outer fixing ring 204, no matter from which direction the ship collides, it will contact the outer surface of the main anti-collision blocks 306;

[0042] After hitting the main anti-collision block 306, the impact force will be transmitted to the inner spring piece 415 in the main anti-collision block 306 through the main anti-collision block 306, and part of the direct contact impact force will be removed through the dual action of the main anti-collision block 306 and the inner spring piece 415;

After the elastic deformation of the upper top spring 411 and the lower top spring 412, the remaining main impact force is relieved;

[0044] After the ship escapes from the collision with the main anti-collision block 306, the main anti-collision block 306 that has been hit will return to its initial position under the action of the self-balancing elastic force of the upper push spring 411 and the lower push spring 412 that are symmetrically distributed on the left and right. Example

[0046] The adjusting hexagon 505 can be screwed by using a standard tool, thereby driving the spring adjusting stud 504 to be threadedly connected to the spring adjusting threaded hole 503, thereby squeezing or relaxing the adjusting compression spring 507, so as to achieve the purpose of changing and adjusting the elastic support of the inner spring 415;

[0047] According to the installation and use environment, the upper top spring 411 and the lower top spring 412 at both ends of the main anti-collision block 306 and the inner spring sheet 415 are adjusted for elastic support force to match the impact force of the ship;

[0048] By screwing the upper push column 409 and the lower push column 410 with a standard tool, the upper push spring 411 and the lower push spring 412 can be squeezed and relaxed, so that the elastic supporting force of the upper push spring 411 and the lower push spring 412 can be adjusted;

[0049] At the same time, by screwing the adjusting hexagon 505 with a standard tool, the adjusting compression spring 507 can be squeezed and relaxed, so that the elastic supporting force of the inner spring sheet 415 on the inner surface of the main anti-collision block 306 can be adjusted.

[0050] Finally, it should be noted that the embodiments listed above are only used to illustrate the technical solutions of the anti-collision process and the anti-collision elastic support force adjustment process of a multi-directional protection self-resetting bridge pier anti-collision structure provided by the present invention, rather than limiting thereof; although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
