The invention relates to the related field of unmanned aerial vehicles and discloses an unmanned aerial vehicle fan blade replacing device. The device comprises a box body, wherein a spline shaft is rotationally arranged in an upper end face of the box body, a movable spline sleeve is connected to an outer circle face of the spline shaft through a spline, and hinge rods symmetrical about the axis of the spline shaft are hinged to an outer circle face of the movable spline sleeve; an outer circle face of the spline shaft is in spline connection with a rotating spline sleeve, and the outer circle face of the rotating spline sleeve is hinged to auxiliary fan blades capable of being hinged to the rotating spline sleeve. According to the unmanned aerial vehicle fan blade replacing device, when high-altitude cutting operation is carried out through the unmanned aerial vehicle fan blades, the fan blades can be replaced in time in the process that the unmanned aerial vehicle is out of control due to the fact that the fan blades collide with foreign matter, so the unmanned aerial vehicle can fly normally, and the unmanned aerial vehicle is prevented from falling to the ground after being out of control; and a phenomenon that the unmanned aerial vehicle collides with pedestrians in the falling process is reduced.

    本发明涉及无人机相关领域,且公开了一种无人机扇叶更换装置,包括箱体,所述箱体上端面内转动设置有花键轴,所述花键轴外圆面花键连接有移动花键套筒,所述移动花键套筒外圆面铰接有关于所述花键轴轴心对称的铰接杆,所述花键轴外圆面花键连接有转动花键套筒,所述转动花键套筒外圆面铰接有能够与所述铰接的辅助扇叶。该一种无人机扇叶更换装置通过无人机扇叶进行高空切割的作业时,扇叶在与异物相撞从而导致无人机出现失控的过程中,能够及时更换扇叶,从而使无人机能够正常飞行,从而避免了无人机失控下坠至地面,并且降低了无人机在下坠过程中与行人碰撞的现象。
