Tower type energy dissipation device for ship interception

Abstract

The invention discloses a tower type energy dissipation device for ship interception. The tower type energy dissipation device is characterized by comprising at least one group of energy dissipation units; each energy dissipation unit comprises a barrel body, an end cover and a plurality of sliding sleeves, wherein the sliding sleeves are arranged in the barrel body and are connected in sequence from inside to outside in a sleeved mode; each end cover is fixedly connected to the front end of the corresponding barrel body; a front positioning convex ring is integrally arranged at the front endof each sliding sleeve; a rear positioning convex ring is integrally arranged at the rear end of each sliding sleeve; an elastic belt is fixedly connected to the front end of each sliding sleeve and is fixedly connected to the corresponding end cover; a first mooring rope is fixedly connected to the sliding sleeve located at the innermost part and penetrates out of the rear end of the corresponding barrel body; and a second mooring rope is fixedly connected to the corresponding end cover. The tower type energy dissipation device has the advantages that when a ship impacts an intercepting device, the energy dissipation device dissipates energy in a mode that the sliding sleeves move to stretch the elastic belts to be fractured, the energy dissipation is large, in addition, the energy dissipation device can be applied to interception of ships with different tonnage, the requirements of different environments can be met, and the flexibility and the universality are good; and in addition,the whole energy dissipation device is convenient to maintain, disassemble and assemble.

Description

technical field [0001] The invention relates to a ship intercepting device, in particular to a tower type energy consumption device for ship intercepting. Background technique [0002] In recent years, more and more attention has been paid to the navigation safety of sea-crossing bridges. Since the sea-crossing bridges have many underwater approach piers in non-navigable waters, these approach piers have weak anti-ship collision capabilities and are easily damaged by ships. In order to prevent the bridge approach piers from being crashed, ship interception devices are usually arranged at a certain distance from these bridge approach piers. The current ship interception device usually absorbs the kinetic energy of the ship hitting the bridge through energy-dissipating components, but for large ships, due to the large kinetic energy of hitting the bridge, the current energy-dissipating components can only absorb part of the collision force of large ships A small part cannot r...
