[0002] A bridge generally refers to a structure erected across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern rapidly developing transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. A bridge generally consists of an upper structure, a lower structure, supports, and ancillary structures. The upper structure, also known as the span structure, is the main structure for crossing obstacles. The lower structure includes abutments, piers, and foundations. The supports are force transmission devices installed at the supporting locations of the span structure and the piers or abutments. The ancillary structures refer to the bridgehead slab, conical slope protection, revetment, diversion projects, etc. The piers at the bottom of the bridge may be hit by passing ships, and a bridge anti-collision device is required. Therefore, a multi-stage buffering energy-absorbing bridge anti-collision device is urgently needed.

The installation steps are simple and convenient for subsequent maintenance and replacement work. During use, if a passing ship collides with the pier 1, the impact energy is absorbed by the combination of compression deformation produced by the fiber energy-absorbing composite material plate 504 and the rubber buffer block 502 in the anti-collision mechanism 5, which can play the role of using softness to overcome hardness, and absorb kinetic energy with both hardness and softness to protect the safety of the pier 1, the ship and personnel. At the same time, when visibility is poor at night, the luminous warning sticker 505 on the outside of the fiber energy-absorbing composite material plate 504 can issue a luminous warning to passing ships, thereby reducing the probability of ship collision accidents. In this way, the operating process of a multi-stage buffer energy-consuming bridge anti-collision device is completed.
