Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of anti-collision device for bridge piers made of polymer composite materials, which solves the problem that most of the existing anti-collision devices for bridge piers in the prior art are fixed on the piers. However, because the water level in the river often changes, when the water level does not When the protective device is passed, the protective device will not be able to protect the problem

Abstract

The invention relates to the technical field of polymer composites, in particular to a polymer composite pier anti-collision device. Comprising an annular anti-collision box arranged outside a pier in a surrounding mode, a floating mechanism and a plurality of energy dissipation columns, the floating mechanism comprises an annular floating bag, a light framework, a connecting plate and a plurality of guide rails, and due to the fact that the annular floating bag is arranged in the light framework and rolling wheels roll on the guide rails, when the water level of a river changes, the energy dissipation columns can dissipate energy through buoyancy of the annular floating bag; the annular box body is installed on a connecting plate of the light framework through a plurality of energy dissipation columns, so that the position of the annular box body is changed along with the water level, and the light framework is lifted in the direction of the guide rail, so that the position of the annular box body is adjusted along with the change of the water level. And the annular anti-collision box can play a protection role all the time.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a collision avoidance device for bridge piers of polymer composite materials. Background technique [0002] When a ship passes through a bridge, the accident that the ship collides with the pier often occurs, resulting in serious consequences such as the destruction of the bridge and the ship, casualties and material loss. In order to avoid the accident of the ship colliding with the pier, it is often necessary to install protective devices on the pier. [0003] In the prior art, a bridge pier anti-collision device is proposed, which includes an annular anti-collision box arranged around the bridge pier and a plurality of anti-collision fenders arranged outside the annular anti-collision box. Boxes and collision fenders dissipate energy, thereby reducing the damage to bridges and ships caused by collision accidents. [0004] However, most of the existing anti...
