Multi-path energy dissipation bridge ship collision prevention device and ship collision prevention system
The invention discloses a multi-path energy dissipation bridge ship collision prevention device which comprises a composite energy dissipation rotating barrel and a fixing mechanism, the composite energy dissipation rotating barrel comprises an inner barrel, a honeycomb layer and a wave-shaped shell, and after the wave-shaped shell on the surface of the composite energy dissipation rotating barrel is impacted by external force, the external force can be quickly decomposed in the tangential direction and the normal direction of an impact surface, and the impact force is reduced; the composite energy-consuming rotary barrel stably rotates, so that the aim of enabling the ship to deviate from the collision direction is fulfilled; due to external force impact, the wave-shaped shell and the honeycomb layer are stressed and deformed, and part of impact energy is absorbed at the same time; a pressure relief opening and a pressure relief valve are arranged on the inner barrel, and when the pressed space of the inner barrel is reduced, the internal pressure is increased, and the pressure reaches the threshold value of the pressure relief valve, liquid in the composite energy consumption rotary barrel is sprayed out from the pressure relief valve; a hydraulic damper of the fixing mechanism buffers residual impact force, so that collision energy is converted into elastic potential energy, internal energy and self kinetic energy of deformation of the composite energy dissipation rotary barrel, kinetic energy of jet water, heat energy of the damper and the like, and the purpose of multi-path energy dissipation and collision prevention is achieved.
本发明公开了一种多途径能量耗散的桥梁防船撞装置，包括复合耗能转桶和固定机构，复合耗能转桶包括内桶、蜂窝层和波浪形外壳，其表面的波浪形外壳，在受到外力撞击后，外力可以迅速沿撞击面的切线和法线方向分解外力，并使复合耗能转桶稳定自转，达到使船舶偏离撞击方向的目的；由于外力撞击，波浪形外壳和蜂窝层受力变形，同时吸收部分撞击能量；内桶上设有泄压口和泄压阀，当内桶受压空间减小、内部压力增加，压力达到泄压阀阈值，复合耗能转桶内的液体从泄压阀喷出；固定机构的液压阻尼器缓冲剩余撞击力，实现碰撞能量转化为复合耗能转桶变形的弹性势能、内能、自身动能、喷射水的动能和阻尼器热能等，以达到多途径能量耗散防撞的目的。
