The invention discloses a cross-medium impact load reduction device which comprises a projectile body, a buffer cabin, a buffer baffle, a pressure relief pipe, a water medium baffle and a limiting assembly, the projectile body is used for loading objects to be protected, the buffer cabin is installed at the bottom of the projectile body to absorb impact force during cross-medium, the buffer baffle is slidably installed in the buffer cabin, and the pressure relief pipe is installed in the water medium baffle. The pressure relief pipe is connected with a drainage hole in the side face of the buffer cabin, the water medium baffle is slidably installed in the pressure relief pipe, and the limiting assembly is used for being in linkage with the buffer baffle and the water medium baffle. Instantaneous impact force is absorbed through air in the air sealing cabin section, and meanwhile high-pressure water in the water medium cabin section is discharged through the pressure relief pipe; after the water medium cabin section is subjected to pressure relief for many times, the impact force is relieved, and impact load reduction can be achieved without additionally arranging a high-strength structure. The invention relates to the technical field of cross-media impact.
本申请公开了一种跨介质冲击降载装置,其包括弹体、缓冲舱、缓冲挡板、泄压管、水介质挡板和限位组件,其中弹体用于装载待保护的物品,缓冲舱安装在弹体的底部以吸收跨介质时的冲击力,缓冲挡板可滑动地安装于缓冲舱内,泄压管与缓冲舱侧面的泄流孔连接,水介质挡板可滑动地安装于泄压管内,限位组件用于联动缓冲挡板和水介质挡板。本申请通过空气密封舱段内的空气吸收瞬时冲击力,同时通过泄压管将水介质舱段内的高压水排出;经过多次对水介质舱段的泄压后,冲击力被缓解,无需额外增设高强度结构即可实现冲击降载。本申请涉及跨介质冲击技术领域。
