The invention provides ventilation and floating equipment for water entry of a navigation body. A floating air bag is installed in the middle rear portion of the navigation body on the equipment; a ventilation structure is arranged in the floating air bag so as to allow gas to flow into the floating air bag conveniently; the ventilation structure is connected with a high-pressure gas tank; a ventilation valve is arranged in a connecting pipe; a ventilation valve is controlled through a timing switch; and when the time is up, the timing switch controls the ventilation valve to be opened, gas in the high-pressure gas tank is inflated into the floating air bag, shielding of a metal shell of the navigation body to remote control signals is avoided, the floating air bag is prevented from expanding, buoyancy is generated, and the navigation body floats to the water surface, so follow-up fishing is facilitated and a floating process is completed. According to the invention, many defects existing in the salvage process of an underwater vehicle in the prior art are overcome, underwater salvage by personnel or a robot is not needed for, the underwater vehicle sinking to the bottom can float to the water surface, and salvage operation is completed on the water surface; so salvage efficiency is improved, and potential safety hazards caused by personnel underwater and economic losses caused by underwater equipment are reduced.

    本发明提出一种航行体入水通气上浮设备,该设备的航行体本体的中后方内部安装上浮气囊,上浮气囊内设置有通气结构,便于气体流入上浮气囊,通气结构与高压气罐连接,在连接管中布置一通气阀门,通气阀门通过定时开关控制,时间设定到时,定时开关控制控制通气阀门打开,高压气罐的气体充入上浮气囊,避免了航行体金属外壳对遥控信号的屏蔽,上浮气囊膨胀,产生浮力,将航行体浮至水面,便于后续打捞,完成上浮的过程。解决了现有技术的入水航行体的打捞过程存在的诸多缺陷,本发明无需人员或者机器人下水打捞,可以将沉底的航行体上浮至水面,在水面上完成打捞作业,提高打捞的效率,减小人员下水安全隐患和下水设备带来的经济损失。
