The invention discloses an undercarriage of a power transmission line inspection unmanned aerial vehicle in the technical field of unmanned aerial vehicles. The undercarriage comprises a connecting assembly, in which inclined supporting rods are symmetrically arranged on the bottom surface of a bearing plate; an undercarriage assembly in which an air compression box is embedded in an inner cavity of the sleeve, and the output end of the air compression box is connected with a three-way pipe; and a positioning assembly which is arranged at the bottom of the bearing plate. Through arrangement of the undercarriage assembly, when the unmanned aerial vehicle has an accident and needs to emergently land on the water surface, the unmanned aerial vehicle slowly lands to make contact with the water surface, a sensing layer transmits a signal to a controller, so that a mounting shaft extends out of a sleeve, and meanwhile, an air bag on the surface of the mounting shaft is gradually expanded, so that the unmanned aerial vehicle can float on the water surface and is avoided from sinking, meanwhile, in order to avoid the unmanned aerial vehicle from flowing along with water flow, when the unmanned aerial vehicle makes contact with the water surface, sponge strips on the unmanned aerial vehicle quickly absorb water to increase the weight, the position of unmanned aerial vehicle is fixed, and follow-up inspection of workers is facilitated.

    本发明公开了无人机技术领域的一种输电线路巡检无人机起落架,包括,连接组件,所述承载板底面对称设有倾斜的支杆;起落架组件,所述套管内腔嵌设有空气压缩盒,所述空气压缩盒的输出端连接有三通管;定位组件,所述定位组件设于承载板底部;本发明通过设置起落架组件,当无人机出现意外情况需要紧急降落至水面上时,无人机缓慢降落至与水面接触,感应层传递信号至控制器,使得安装轴向套管外伸出,同时其表面的气囊袋逐渐膨胀,使得无人机能够漂浮于水面上,避免出现下沉的问题,同时为了避免无人机随着水流流动的问题,在无人机接触水面时,其上的海绵条快速吸水增加重量,对无人机起到定位的作用,便于后续工作人员的巡回。
