The invention belongs to the technical field of unmanned aerial vehicles, particularly relates to an anti-collision type fixed-point unmanned aerial vehicle, and aims at solving problems that if an existing plant protection unmanned aerial vehicle collides with an obstacle in a flying process, an anti-collision effect is poor, an angle of a spray head on the unmanned aerial vehicle is fixed, and the angle of the spray head cannot be adjusted. According to the scheme, the unmanned aerial vehicle comprises a vehicle body, first flying paddles are annularly arranged on a periphery of an outer wall of the vehicle body, a second flying paddle is hinged to a bottom end of each first flying paddle, and an anti-collision mechanism annularly arranged on the periphery of the outer wall of the vehicle body is arranged on one side of each second flying paddle. According to the anti-collision mechanism, under cooperation of a fixed outer rod, a telescopic inner rod, an anti-collision plate, an airbag, a piston column, a fixed cylinder, a compression spring and a connecting pipe, when the vehicle body collides with the obstacle, the vehicle body can be prevented from being collided again, the anti-collision effect of the vehicle body is further improved, a protection effect on the vehicle body is enhanced, and a collision damage rate of the vehicle body is reduced.

    本发明属于无人机技术领域,尤其是一种防撞式定点无人机,针对现有的植保无人机,其无人机在飞行过程中若是撞击到障碍物,防撞效果差,且无人机上的喷头的角度固定,无法对喷头的角度进行调节的问题。现提出如下方案,其包括机体,所述机体的外壁四周环设有飞行桨体一,每个飞行桨体一的底端均铰接有飞行桨体二,飞行桨体二的一侧设有环设在机体外壁四周的防撞机构。本发明防撞机构中,在固定外杆、伸缩内杆、防撞板、气囊、活塞柱、固定筒、压缩弹簧以及连接管的配合下,能够在机体撞到障碍物时,避免机体再次受到撞击,进一步提高了机体的防撞效果,增强了对机体的防护效果,降低了机体的撞击损坏率。
