AI Technical Summary

Technical Problem

Existing ship collision avoidance devices are unable to effectively cope with impacts or shocks caused by localized high stress, leading to the failure of elastic buffers in the elastomeric system and resulting in damage to the ship's side.

Method used

The integrated ship collision avoidance device adopts a collision avoidance plate combined with a triangular cell cavity structure. It utilizes the triangular prism cavity and slot design within the polyurethane elastomer and achieves a firm connection between the collision avoidance plate and the polyurethane elastomer through bolt fixing and adhesive bonding, dispersing the impact force into the overall cavity.

Benefits of technology

It improves the ship's puncture resistance and energy absorption efficiency, and enhances its protection against localized high stress.

Abstract

This invention provides an integrated, interconnected ship collision avoidance device. A flat slot is provided on the upper layer of a polyurethane elastomer, with the slot opening located on the side of the polyurethane elastomer. A collision avoidance plate is fixed inside the slot. The polyurethane elastomer has a hollow structure, with a first cavity and a second cavity arranged in a triangular prism shape along either the transverse or longitudinal direction. Both the first and second cavities have triangular cross-sections, with the apex of the first cavity facing upwards and the apex of the second cavity facing downwards. The first and second cavities are staggered. This ship collision avoidance device, employing a collision avoidance plate combined with a triangular cell cavity structure, can achieve integrated operation under impact or shock of localized high stress, improving energy absorption efficiency and thus protecting the ship.
