Suspension type anti-ship-collision multilayered energy consumption device

Abstract

The invention discloses a suspension type anti-ship-collision multilayered energy consumption device. The suspension type anti-ship-collision multilayered energy consumption device comprises an anti-collision box, an L-shaped base buoyancy tank and a buffer device, wherein the anti-collision box is arranged at the outermost side and provided with the inclination angle; the base buoyancy tank is connected with a bridge pier and carries the anti-collision box; and the buffer device is arranged between the base buoyancy tank and the external anti-collision box. When a ship body collides with theenergy consumption device, energy is consumed through large deformation of the buffer device. The bearing surface of the base buoyancy tank is higher than the horizontal plane, the problem that the buffer device is soaked in water to be rusted is prevented, and durability is improved. The thin wall of the outer side of the anti-collision box is inclined downwards, the anti-collision box can be prevented from warping upwards in the ship collision process, and the optimal working performance of the buffer device is guaranteed. According to the suspension type anti-ship-collision multilayered energy consumption device, the whole device can float on the water surface by means of the base buoyancy tank; the impact force is directly borne through the external anti-collision box in the ship collision process; meanwhile, a majority of collision force is transmitted to the buffer device to be squeezed passively and deformed for energy consumption, and thus, the impact force borne by the bridgepier is reduced; and damage of the device is reduced to the greatest extent while safety of a bridge and a ship is guaranteed.

Description

technical field [0001] The invention relates to a bridge anti-ship collision device, in particular to a suspended type anti-ship collision energy consumption device. Background technique [0002] The number of bridges built in wide waters and open seas and deep water environments is increasing, which has played an indispensable role in the rapid development of highways and railways and the growth of the national economy. However, these bridge structures located in navigable deep-water waters are artificially constructed obstacles for water transport ships, and there is a risk of ship collision, and this risk exists objectively throughout the entire life of the structure. In the event of a ship collision accident, the bridge structure may need to bear a huge lateral impact load, and the bridge in the design navigable waters must give full consideration to the ship collision problem. Otherwise, it may lead to serious damage to the bridge structure, or even complete collapse, ...
