Abstract

The invention discloses a self-floating collision prevention device based on composite materials; and the device coasts a stand column of a marine structure, and floats up and down along with a water level. The device is characterized by forming a ring body by multiple connected collision prevention units; the cross sections of the collision prevention units are fan rings, and the longitudinal sections are ellipses; and the collision prevention units are formed by glass fiber resins, corrugated sandwich steel plates, polyurethane elastomers, inner-layer steel plates and polyurethane foam multilayer composite materials from edge to internal in sequence, wherein an internal space formed by the inner-layer steel plates is filled with polyurethane foams. The self-floating collision prevention device is stable in water property, resistant in corrosion, excellent in impact resistance, and green and environment-friendly.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to a self-floating anti-collision device based on composite materials. Background technique [0002] Most domestic protection devices adopt structural forms such as steel sleeve boxes and steel pontoons. The material is basically a single high-strength steel. The steel plate and steel rods form a truss support system. When a collision occurs, a large amount of energy is absorbed through the crushing and deformation of the steel plate. However, welding and riveting are mostly used for the connection between the parts of the device, and the cost is high due to strict manufacturing limits and many complicated welding details, and the quality is difficult to guarantee. [0003] In recent years, Liu Weiqing, Fang Hai and others have proposed a space lattice web-reinforced foam sandwich structure based on fiber-reinforced composite materials. This protective device can adapt to seawater corrosi...
