The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to an unmanned aerial vehicle emergency water surface landing floating supporting device which comprises a vehicle body, a pair of box bodies are fixed to the top of the vehicle body, an outlet is formed in one side of each box body, a winding drum is rotationally connected into each box body through a center shaft, and a floating belt is wound on each winding drum. A balance weight capable of being inserted into the outlet is fixed to the free end of the floating belt and detachably connected with the box body, a handle wheel is fixed to one end of the center shaft, and a push-out mechanism is arranged on the box body. According to the unmanned aerial vehicle, when the unmanned aerial vehicle lands emergently, the push-out mechanism pushes away the balance weight from the box body, the balance weight and the exposed part of the floating belt can continuously pull out the remaining floating belt from the winding drum due to wind resistance, and the floating belt pulled out is more and more, so that the landing speed can be slowed down in the landing process of the unmanned aerial vehicle through the floating belt; and finally, the unmanned aerial vehicle floats on the water surface under the buoyancy action of the floating belt.

    本发明属于无人机技术领域,尤其是一种用于无人机紧急水面着陆浮动支持装置,包括机体,机体顶部固定有一对箱体,箱体的一侧设有出口,箱体内通过中心轴转动连接有卷筒,卷筒上缠绕有浮带,浮带的自由端固定有能够插在出口内的配重,配重与箱体可分离连接,中心轴的一端固定有手柄轮,箱体上设置有推出机构。本发明中,在无人机紧急降落时推出机构将配重从箱体上推离,配重和浮带暴露出来的部分由于受到风阻,就会将剩余的浮带从卷筒上持续拉出,随着被拉出的浮带越来越多,这样就可以通过浮带在无人机降落过程中减缓降落速度,并且最终通过浮带的浮力作用使得无人机漂浮在水面。
