The invention discloses a seawater excitation type unmanned aerial vehicle emergency floating inflation device, and relates to the field of inflation devices. The seawater excitation type unmanned aerial vehicle emergency floating inflation device comprises a compressed gas cylinder, a gas source release valve connected with a gas cylinder connector of the compressed gas cylinder and a seawater excitation device connected to the gas source release valve. The air source release valve comprises a valve body provided with a valve cavity, an isolating membrane arranged in the valve cavity, a firing pin movably arranged in the valve cavity, a spring with the two ends abutting against the firing pin and the valve cavity respectively and an abutting column used for abutting against and limiting the position of the firing pin, the isolating membrane is used for isolating the connector and the valve cavity, and the valve body is connected with an air outlet communicated with the valve cavity; the seawater excitation device is used for releasing the limitation of the ejection column on the striker when being in contact with seawater, so that the spring pushes the striker to pierce the isolating membrane. The seawater excitation type unmanned aerial vehicle emergency floating inflation device can be matched with the buoy to achieve automatic inflation, opening and forming of the buoy when entering water, and therefore the unmanned aerial vehicle which is urgently landing on the water stably floats on various seas to execute tasks.

    一种海水激发式无人机应急漂浮充气装置,涉及充气装置领域。海水激发式无人机应急漂浮充气装置包括压缩气瓶、与压缩气瓶气瓶接口连接的气源释放阀及连接于气源释放阀的海水激发装置,气源释放阀包括设有阀腔的阀体、设于阀腔内的隔离膜、可移动地设于阀腔内的击针、两端分别抵压击针和阀腔的弹簧及用于抵压限定击针位置的顶紧柱,隔离膜用于隔离接口和阀腔,阀体连接有与阀腔连通的出气口;海水激发装置用于在接触海水时解除顶紧柱对击针的限定,使弹簧推动击针刺穿隔离膜。海水激发式无人机应急漂浮充气装置能够与浮筒配合实现入水时浮筒自动充气打开成型,从而使紧急迫降在水上的无人机稳定漂浮于各种海上执行任务的无人机加装应急漂浮装置。
