An underwater deep-falling emergency floating device for a submersible comprises a bulkhead, a through hole is formed in the bulkhead, and a convergent-divergent spray pipe penetrates through the through hole; a gas generator is connected with the position, located on the inner side of the bulkhead, of the convergent-divergent spray pipe, an igniter and reactants are arranged in the gas generator,and a double-layer filter screen is installed at the communication position of the gas generator and the convergent-divergent spray pipe; the emergency floating device further comprises a control panel, and the control panel is communicated with the igniter through a lead; an air bag is connected with the position, located on the outer side of the bulkhead, of the convergent-divergent spray pipe,and an opening of the air bag communicates with the convergent-divergent spray pipe. The emergency floating device is arranged on the bulkhead of the submersible, buoyancy needed by underwater depthfalling of the submersible can be conveniently provided, the depth falling retrieval time is shortened, when the submersible suddenly meets underwater depth falling, the emergency floating device sends out an ignition instruction, and the buoyancy needed by depth falling retrieval can be obtained within dozens of milliseconds.
一种潜水器水下掉深应急浮起装置,包括舱壁,所述舱壁上开有穿通孔,所述穿通孔内穿过缩放喷管;所述缩放喷管位于舱壁内侧位置处连接有气体发生器,所述气体发生器的内部设置有引爆装置和反应物,所述气体发生器与缩放喷管连通处安装有双层过滤网;应急浮起装置还包括控制面板,所述控制面板通过引线与引爆装置连通;所述缩放喷管位于舱壁外侧位置处连接有气囊,气囊的开口与缩放喷管连通。通过在潜水器的舱壁上设置应急浮起装置,可以方便的提供潜水器水下掉深所需浮力,减少掉深挽回时间,当潜水器突遇水下掉深时,应急浮起装置发出点火指令,在几十毫秒的时间内即可获得掉深挽回所需的浮力。
