The invention belongs to the technical field of unmanned aerial vehicles, particularly relates to a plant protection unmanned aerial vehicle, and provides the following scheme for solving the problemthat an existing unmanned aerial vehicle is poor in damping effect: the plant protection unmanned aerial vehicle comprises a rack, a plurality of sleeves are fixed to the bottom of the rack, supporting rods are arranged at the bottoms of lantern rings, and bases are fixed to the bottoms of the two supporting rods; first permanent magnets are adhered to the tops of the inner walls of the sleeves; aplurality of first springs are fixed to the bottoms of the first permanent magnets, a slide rheostat is fixed to the bottoms of the first springs, an electromagnet is fixed to the top of the slide rheostat, and the bottom of the slide rheostat is fixedly connected with the supporting rods. In the invention, when the slide rheostat moves upwards, the slide sheet relatively moves downwards, so thatthe resistance of the slide rheostat is reduced, and the magnetism of the electromagnet is gradually enhanced by gradually increasing the current in the electromagnet, so that the magnetic repulsionbetween the electromagnet and the first permanent magnet is gradually increased, and on the contrary, the magnetic repulsion is gradually reduced; therefore, the damping effect is further achieved.

    本发明属于无人机技术领域,尤其是一种植保无人机,针对现有无人机减震效果不佳的问题,现提出以下方案,包括机架,机架底部固定有多个套管,套环底部设置有支撑杆,两个支撑杆底部固定有底座,所述套管内壁顶部粘接有第一永磁铁,第一永磁铁底部固定有多个第一弹簧,多个第一弹簧底部固定有滑动变阻器,滑动变阻器顶部固定有电磁铁,滑动变阻器底部和支撑杆之间固定连接。本发明中,滑动变阻器向上移动的过程中,滑片相对向下移动,使得滑动变阻器的电阻减小,通过电磁铁中的电流逐渐增加,使得电磁铁的磁性逐渐增强,使得电磁铁和第一永磁铁之间的磁斥力逐渐增加,相反的,磁斥力逐渐减小,从而进一步达到减震的效果。
