Benefits of technology

The present invention is about creating a device that can prevent collisions on bridges. The device is made of a special material that can absorb the energy of a collision fully. It is affordable, can be applied in a wide range of situations and is friendly to the environment. The main goal is to improve the effectiveness and reduce the cost and difficulty of repairing existing anti-collision devices.

Problems solved by technology

Many accidents of collision between a ship and a bridge at least lose tens of thousands of dollars, more seriously, casualties occur, and the loss amounts to millions, tens of millions or even billions of dollars; it is more difficult to calculate enormous indirect loss.
The anti-collision method of the indirect type is done once for all, but the shipping lane may be affected, and usually the indirect type is abandoned since the manufacturing cost is excessively high or the condition is not met.
However, the steel casing box generally bears collision once, repair is difficult after the steel casing box is damaged due to the collision; meanwhile, during collision, the ship body is susceptible to damage; additionally, the steel products are easily rusted in water over years, and maintenance expenses are high, so it is extremely urgent to design and develop an innovative anti-collision system made of a new material.

Abstract

An anti-collision device made of a buffering energy-absorbing type web-enhanced composite material, including an anti-collision unit. The anti-collision unit includes a housing and a filling material body located in the housing, and the housing is a solid housing formed of a composite material surface layer or a sandwiched housing formed of a composite material surface layer internally filled with a sandwiched material, and the sandwiched material; the filling material body includes a space lattice body and an energy consuming material, the space lattice body is formed of fiber webs arranged in the housing in a single-layered unidirectional, single-layered bidirectional, multi-layered unidirectional or multi-layered multi-directional manner, and the energy consuming material is located between the fiber webs and / or between the fiber webs and inner walls of the housing.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a bridge or dock anti-collision structure, in particular, to a low-cost and green anti-collision device made of a composite material, and specifically to an anti-collision device made of a buffering energy-absorbing type web-enhanced composite material, which is applicable to piers, bridge towers, and bearing platforms of various bridges, docks, waterborne buildings, seaborne buildings and ships and used for alleviating a collision disaster from a ship, a floating ice or a vehicle.[0003]2. Related Art[0004]It is well-known that, accidents of collision between a ship (vehicle) and at bridge continuously occur around the world all the time, and the frequency of accidents of collision between a ship and a bridge is far higher than our imagination. Casualties, property loss and environment damage caused by accidents of collision between a ship and a bridge are amazing. Many accidents of coll...
