The invention belongs to the technical field of unmanned aerial vehicles, particularly relates to a landing protection device for a plant protection unmanned aerial vehicle, and aims at the problem that the plant protection unmanned aerial vehicle is prone to rollover due to the influence of inertia during landing, the rotor wings of the unmanned aerial vehicle are damaged and the use cost of theunmanned aerial vehicle is influenced. The following scheme is provided: the landing protection device comprises a plurality of mounting pipes with arc-shaped structures, connecting rods with arc-shaped structures are inserted between the end parts of two adjacent mounting pipes, supporting rods are fixedly mounted at the bottom ends of the mounting pipes, and supporting mechanisms are in threadedconnection with the bottom ends of the supporting rods. The unmanned aerial vehicle falls onto the landing bedplate during landing to provide buffer protection for the unmanned aerial vehicle and collision during landing of the unmanned aerial vehicle is reduced; and when falling down, the support at the bottom of the unmanned aerial vehicle is inserted among the multiple hooking mechanisms, thetop ends of the hooking mechanisms are stressed and extruded to deviate, after the unmanned aerial vehicle is parked, the hooking mechanisms are influenced by elastic force to reset, then the supportat the bottom of the unmanned aerial vehicle is hooked, and the phenomenon that the unmanned aerial vehicle turns over due to inertia influence is avoided.

    本发明属于无人机技术领域,尤其是一种植保无人机用降落保护装置,针对植保无人机降落时容易受到惯性的影响造成侧翻,造成无人机旋翼的损坏,影响无人机使用的成本问题,现提出以下方案,包括多个弧形结构的安装管,相邻的两个所述安装管端部之间插接有弧形结构的连接杆,且安装管的底端固定安装有支撑杆,所述支撑杆的底端螺接有支撑机构。本发明中无人机在降落时落入到降落台板上方对无人机提供缓冲保护,减少无人机降落时受到的碰撞,且无人机底部的支架下落时插入多个勾合机构之间,勾合机构的顶端受力挤压发生偏移,在无人机停放后勾合机构受到弹力影响复位,进而将无人机底部的支架勾住,避免无人机受到惯性影响发现侧翻现象。
