The invention relates to the technical field of unmanned aerial vehicle protection, and discloses a plant protection unmanned aerial vehicle collision protection device which comprises a body and further comprises a plurality of circularly-distributed supporting arms arranged on the outer ring of the body, anti-collision mechanisms are arranged on the supporting arms and connected with limiting mechanisms, and a damping mechanism is arranged at one end of the body and connected with the limiting mechanisms. The damping mechanism is used for reducing the impact force during landing of the unmanned aerial vehicle; when the unmanned aerial vehicle works and the outer ring of the unmanned aerial vehicle collides with an object, the anti-collision plate located on the outermost periphery of the unmanned aerial vehicle plays a role in protecting a fan and a supporting arm of the unmanned aerial vehicle, the anti-collision plate can absorb part of collision force through arranged second springs, and when the anti-collision force borne by the anti-collision plate is too large, the anti-collision plate is prevented from falling off. And the arranged limiting mechanism can limit the movement of the anti-collision plate and enable the limiting plate to be clamped into the limiting groove of the anti-collision plate, so that the fan and the supporting arm of the unmanned aerial vehicle can be protected in all directions, the fan and the supporting arm are prevented from being collided by an object, and the effect of protecting the unmanned aerial vehicle is achieved.

    本发明涉及无人机保护技术领域,公开了一种植保无人机碰撞保护装置,包括本体,还包括:所述本体外圈设置有多个呈圆形分布的支臂,支臂上设置有防撞机构,所述防撞机构连接有限位机构,所述本体一端设置有减震机构,减震机构用于减轻无人机降落时的冲击力;在工作时,当无人机的外圈碰撞到物体时,位于无人机最外围的防撞板起到保护无人机的风扇和支臂的作用,通过设置的第二弹簧可以使防撞板吸收部分的撞击力,且当防撞板受到的防撞力度过大时,设置的限位机构可以限制防撞板的移动,并使限位板卡入防撞板的限位槽内,进而可以实现对无人机的风扇和支臂的全方位保护,避免风扇和支臂受到物体撞击,起到保护无人机的作用。
