The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a plant protection unmanned aerial vehicle with anti-falling protection, which comprises an unmanned aerial vehicle body, the unmanned aerial vehicle body is provided with a placing mechanism, the placing mechanism is provided with a high-pressure gas cabin and a speed reducing mechanism, and the speed reducing mechanism is located at the uppermost part of the whole unmanned aerial vehicle device. The density of gas filled in the high-pressure gas cabin is smaller than that of air; supporting legs used for supporting are arranged below the unmanned aerial vehicle body, and nozzles with the downward air injection direction are arranged on the supporting legs. The speed reducing mechanism comprises a storage box, a speed reducing parachute is arranged in the storage box, the speed reducing parachute is of an interlayer structure, the interior of the interlayer is a cavity, the cavity is connected with a high-pressure gas cabin, gas is injected into the cavity of the speed reducing parachute through the high-pressure gas cabin to enable the cavity of the speed reducing parachute to expand, and therefore the speed reducing parachute can be thrown out of the storage box of the speed reducing mechanism conveniently. After the cavity of the brake parachute is filled with gas, the brake parachute is easier to unfold after being thrown out.

    本发明属于无人机技术领域,具体涉及一种带有防坠保护的植保无人机,包括:无人机本体,所述无人机本体上安装有放置机构,所述放置机构上分别安装有高压气舱和减速机构,所述减速机构位于整个无人机装置的最上方,所述高压气舱内填充的气体密度比空气小;所述无人机本体的下方设置有用于支撑的支腿,所述支腿上设置有喷气方向朝下的喷嘴;所述减速机构包括有收藏盒,所述收藏盒内设置有减速伞,其中,所述减速伞为夹层结构,夹层内部为空腔,所述空腔与高压气舱连接,通过高压气舱向减速伞的空腔注入气体,使其产生膨胀,从而便于减速伞从减速机构的收藏盒中被抛出,另外,减速伞的空腔被气体充满之后,在抛出后更容易展开。
