An anti-fall and anti-drift unmanned aerial vehicle comprises an unmanned aerial vehicle body (1). At least one rotor (10) is disposed on the unmanned aerial vehicle body (1). Wings (3) are respectively disposed on the left side and the right side of the unmanned aerial vehicle body (1). An air bag (2) is disposed each wing (3) respectively. Protrusions (21) protruding downwards are disposed at the bottoms of the air bags (2). The two air bags (2) are located at the positions at the same height. The two air bags (2) are symmetrically disposed on the basis of the unmanned aerial vehicle body (1). Gas lighter than air is injected into the air bags (2). The air bags (2) are respectively disposed on the two sides of the unmanned aerial vehicle body (1), and therefore when the aerial vehicle lands, the air bags (2) can serve as an undercarriage. The beneficial effects that buffering is achieved and damage to the unmanned aerial vehicle body (1) is reduced can be achieved when the aerial vehicle falls and is exploded and falls to the ground. If the aerial vehicle falls to fields or water surfaces by accident, the aerial vehicle can float on the water surfaces under the action of the air bags (2), damage caused when the aerial vehicle sinks into water is avoided, and the safety performance of the aerial vehicle is improved. In addition, the protrusions (21) protruding downwards are disposed at the bottoms of the air bags (2), and therefore when the spraying work is conducted, the protrusions (21) can block side wind to reduce drifting of mist drops, and the utilization efficiency of the mist drops is improved.
