Explosion-proof structure and explosion-proof wall for offshore platform
The invention discloses an explosion-proof structure. The structure comprises a wave reduction assembly and a wave absorbing assembly, wherein the wave reduction assembly can reduce shock waves generated by explosion, the wave absorbing assembly further absorbs the shock waves, the wave reduction assembly comprises a perforated bent plate and a connecting plate which are sequentially distributed along an explosion facing surface, the bent plate has a certain reflection effect and changes the entering angle of the shock waves, and the connecting plate is connected with the bent plate and the wave absorbing assembly to form a wave reduction cavity. After the shock waves enter the wave reduction cavity from different directions, air vortexes are generated in the cavity and counteract one another to a certain extent, energy dissipation of the shock waves is caused, therefore the impact effect on the explosion-proof structure is reduced, the explosion-proof effect of the explosion-proof structure is strengthened, the wave absorbing assembly is of a multi-layer plate-shaped structure and is arranged in the direction deviating from the explosion facing surface, a buffer interlayer absorbsexplosion energy, a supporting layer is a high-strength steel plate, the deformation amount of the explosion-proof structure is reduced, the protection effect is better achieved, and the explosion-proof performance of the explosion-proof structure is further improved.
本发明公开了一种防爆结构，包括消波组件和吸波组件，消波组件能够削减爆炸产生的冲击波，吸波组件则进一步吸收冲击波，消波组件包括沿迎爆面依次分布的带孔折弯板和连接板，折弯板具有一定的反射效果，并改变了冲击波进入的角度，连接板连接折弯板和吸波组件构造出消波腔，冲击波从不同的方向进入消波腔后，会在腔室内产生空气漩涡，并且在一定程度上发生相互抵消，造成冲击波自身能量耗散，从而降低其对防爆结构的冲击作用，加强了防爆结构的防爆效果，吸波组件为多层板状结构且设置在背离迎爆面的方向，缓冲夹层吸收爆炸能量，支撑层为高强度钢板，减小防爆结构的变形量，更好得起到防护作用，进一步提升防爆结构的防爆性能。
