The invention discloses a falling protection device for an unmanned aerial vehicle in the technical field of unmanned aerial vehicles. The device comprises an unmanned aerial vehicle body and multiplespeed measurement sensors. The plurality of speed measuring sensors are fixed on the body of the unmanned aerial vehicle body and are opposite to the power rotating shaft; a mounting ring plate is fixed at the bottom of the body of the unmanned aerial vehicle body through screws; four groups of U-shaped seats are fixed on the lower surface of the mounting ring plate in a rectangular shape; an inner cavity of the U-shaped seat is rotationally and obliquely connected with a first spring rod through a rotating shaft and a torsional spring; power supply is realized through peripheral rechargeablebattery, when an unmanned aerial vehicle system line has a fault or loses power, the high-pressure electromagnetic valve can still be triggered to be opened by detecting the rotating speed of the motor shaft normally, the four air bags are inflated and arranged below, the buffering, decelerating and floating supporting effects are achieved, then the unmanned aerial vehicle floats on the water surface, water seepage in an unmanned aerial vehicle body is avoided, and the device is high in automation degree and obvious in effect and has market popularization value.

    本发明公开了无人机技术领域的一种用于无人机坠落防护装置,包括无人机本体和若干测速传感器,若干测速传感器固定在无人机本体的机体上并正对动力转轴,无人机本体的机体底部通过螺钉固定有安装圆环板,安装圆环板的下表面呈矩形固定有四组U型座,U型座的内腔通过转轴和扭簧转动倾斜连接有第一弹簧杆,通过外设充电电池供电,当无人机系统线路发生故障或失电时,仍然可以正常通过检测电机轴的转速来触发高压电磁阀打开,使四组气囊充气,气囊设置在下方,起到缓冲、减速和漂浮支撑作用,进而使无人机漂浮在水面上,避免无人机机体内渗水,该装置自动化程度高,效果明显,具有市场推广价值。
