Floating type ship collision prevention system with metal dampers

Abstract

A floating type ship collision prevention system with metal dampers is formed by a floating body, anchors, rope chains and the metal dampers. The floating body is moored through the anchors and the rope chains. The metal dampers are mounted on the floating body and connected with the rope chains. When the floating body is pushed by a ship to move, the metal dampers bear the function of tension of the rope chains, and therefore materials of the metal dampers deform, resistance is provided, the situation that the ship moves towards a pier to consume ship kinetic energy is avoided, and the moving direction of the ship is changed so that the ship can avoid the pier. The floating type ship collision prevention system with the metal dampers is high in ship stop capacity, relative constancy is kept, and the maintenance workload is low.

Description

technical field [0001] The invention relates to a bridge anti-ship collision system, in particular to a separate mooring floating anti-ship collision system for protecting bridge piers. Background technique [0002] Known pier anti-ship collision facilities mainly contain two types. [0003] One is the attached anti-collision facilities installed on the bridge piers. There are relatively many engineering applications. The structural deformation of the anti-collision facilities is mainly used to consume the kinetic energy of the ship, prolong the impact time, and reduce the impact force of the ship. However, due to the attached anti-collision facilities The amount of deformation is limited, and the pier will still be subjected to a large force. The installation cost of the attached anti-collision facilities is high, and it is difficult to repair after being hit by a ship, which is not conducive to protecting the ship in an accident, and will also increase the wave and curren...

AI Technical Summary

Problems solved by technology

For fixed anti-collision facilities such as independent anti-collision piers and artificial islands, not only the construction and installation costs are high, but also it is not conducive to the protection of accident ships.

For the mooring floating body, the gravity anchor can be used to move the anchor or the deformation of the polymer cable can consume energy, which is beneficial to protect the ship in an accident. However, due to unfavorable factors such as the gravity anchor may be trapped in the mud and cannot move the anchor, and the bearing capacity of the polymer material will decrease after aging, it is necessary to Timely maintenance can play a role

In addition, in order to protect the pier, the distance from the anti-collision facilities to the pier is limited, usually only a few tens of meters. When it is necessary to block large ships, the anti-collision facilities will be required to provide greater resistance. The floating body is difficult to meet the requirements
