The invention discloses an emergency landing protection device for an electric power inspection unmanned aerial vehicle, and relates to the technical field of emergency landing protection of unmanned aerial vehicles. A mounting seat is arranged on an unmanned aerial vehicle main body, a telescopic pipe is arranged on the mounting seat, a reaction cylinder is arranged in the telescopic pipe, the reaction cylinder is fixedly connected with the unmanned aerial vehicle main body, and the reaction cylinder is filled with a gas generating agent; an electrothermal generator connected with a gas generating agent is arranged at the lower part of the reaction cylinder, an opening is formed in the upper part of the reaction cylinder, an upper cover is slidably arranged at the opening, and a parachute assembly is arranged at the orifice of the telescopic pipe; an elastic buffering support is arranged on the lower portion of the unmanned aerial vehicle body. The parachute assembly and the unmanned aerial vehicle body are connected through the telescopic pipe, so that the distance between the parachute assembly and the unmanned aerial vehicle body is increased after the parachute assembly is opened, and the parachute is prevented from being scraped by paddles of the unmanned aerial vehicle body. The problems that an emergency parachute of an existing unmanned aerial vehicle is easily wound by a propeller of the existing unmanned aerial vehicle and a bearing protection device is too heavy in structure are solved.

    本发明公开了一种电力巡检无人机紧急降落保护装置,涉及无人机紧急降落保护技术领域,通过在无人机主体上设有安装座,安装座上设有伸缩管,伸缩管内部设有反应筒,反应筒与无人机主体固定连接,反应筒内部填充有气体发生剂,反应筒下部设有与气体发生剂相连接的电热发生器,反应筒上部开口且开口处滑动设有上盖,伸缩管的管口处设有降落伞组件;无人机主体下部设有弹性缓冲支架。通过设置伸缩管将降落伞组件和无人机主体连接,使降落伞组件在打开后到无人机主体的距离增加,避免降落伞被无人机主体的桨叶刮到,本保护装置更加轻量化,解决了现有无人机的紧急降落伞容易被自身螺旋桨缠绕、背负的保护装置结构过于笨重的问题。
