Suspension type ship collision preventing energy consuming device

Abstract

The invention provides a suspension type ship collision preventing energy consuming device. The suspension type ship collision preventing energy consuming device comprises a rotating energy dissipating device, a buffering device and a suspended guide rail, wherein the rotating energy dissipating device is arranged at an upstream face or / and a downstream face of the outer side of a bridge pier; thebuffering device is suspended in water; the suspended guide rail is arranged between the buffering device and the bridge pier; and when a ship collides the rotating energy dissipating device, the rotating energy dissipating device is used for steering the ship prow and cooperates with the suspended guide rail to drive a collision preventing device to rotate entirely. According to the suspension type ship collision preventing energy consuming device provided by the invention, the rotating energy dissipating device cooperates with the suspended guide rail to steer the ship prow before the shipcollides the bridge pier so as to realize passive avoidance, thus the collision force born by the bridge pier is reduced, the safety of a bridge and the ship is guaranteed, and damages of the suspension type ship collision preventing energy consuming device are reduced as far as possible.

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] Since the 1980s, my country has built more and more bridges in wide waters and open seas and deep waters, which have 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 col...

AI Technical Summary

Problems solved by technology

At present, the most widely used anti-ship collision device in China is the steel structure fender with obvious advantages in terms of anti-collision range, reduction of ship damage, economy, etc., but the steel itself is easy to corrode, making the steel structure fender in bridge service The maintenance cost remains high within the time limit. At this time, it is necessary to develop a new type of anti-collision equipment that takes into account the advantages of steel structure fenders and has good durability.
