The invention discloses a safe plant protection unmanned aerial vehicle which comprises a rack. A plurality of rotor wing rods are arranged on the rack, rotor wings driven by a driving motor are fixedly connected to positions at the ends, far away from each other, of the rotor wing rods, anti-falling buffering devices are fixedly connected to the outer surfaces of the middle positions of the rotorwing rods, air pumps are arranged in the anti-falling buffering devices, and air bags are further arranged in positions, close to the bottoms, of the inner surfaces of the anti-falling buffering devices. When the plant protection unmanned aerial vehicle does not take off, the working air bags of the air pumps swell to bulge to play a role of supporting a foot stool. After the unmanned aerial vehicle takes off, the air pumps work to discharge gas in the air bags and to retract the air bags in the anti-falling buffering devices. When the plant protection unmanned aerial vehicle is tended to crash, the air pumps work and the air bags swell again to play a decelerating role. Meanwhile, when the plant protection unmanned aerial vehicle falls onto the ground, a buffer protection role is played,so that the safety of the plant protection unmanned aerial vehicle is improved.
本发明公开了一种安全性植保无人机,包括机架,所述机架上设置有多个旋翼杆,所述旋翼杆相互远离一端的位置固定连接有由驱动电机驱动的旋翼,所述旋翼杆的中部位置的外表面固定连接有防坠缓冲装置,所述防坠缓冲装置内设置有气泵,所述防坠缓冲装置内表面靠近其底部的位置还设置有气囊;本发明通过植保无人机未起飞时,气泵工作气囊膨胀鼓出,可起到支撑脚架的作用,无人机起飞以后,气泵工作,将气囊内的气体排出,将气囊收入防坠缓冲装置内,当植保无人机具有坠毁迹象时,气泵工作,气囊再次膨胀,可起到减速的作用,同时其落到地面时,也具有缓冲保护的作用,提高了植保无人机的安全性。
