Portable unmanned plane

Abstract

The invention discloses a portable unmanned plane, belongs to the technical field of aviation systems, and aims to solve the problems that in the prior art, the bottom of a conventional unmanned planeis in a spherical shape, the landing is unstable, and in the rainy days, the short circuit of the unmanned plane happens easily. The middle of the spherical body of the unmanned plane is provided with a water tank; a water cavity is arranged in a foldable plane arm; the water cavity is hermetically connected to the water tank through a pipeline; the highest point of the plane arm is provided witha water storage tank that is communicated with the water cavity; the bottom of the water cavity is provided with a wrinkled waterproof film; the position of the waterproof film is corresponding to one side, which faces the water storage tank, of the hollow part of the plane arm, after the waterproof film is unfolded, the hollow part of the plane arm can be covered by the waterproof film; a rotarygear and a rack engaged with the gear are vertically arranged in the water tank, the opening of the pipeline is arranged in one side above the gear, the top of the rack is connected to an umbrella like member, the umbrella like member can stretches out from the opening in the top of the water tank; one side, which is far away from the body, of the water cavity is provided with a sliding piston, apiston is fixedly connected to a support leg that can stretches out of the plane arm, and the piston is connected to the water cavity through a tension spring.

Description

technical field [0001] The invention belongs to the technical field of aviation systems, and in particular relates to a portable unmanned aerial vehicle. Background technique [0002] Nowadays, drones are widely used in aerial surveying and mapping, film and television shooting, enemy situation survey, disaster detection, power inspection and other fields, and are the best in the aircraft family. Among them, multi-rotor UAVs have extremely important military and civilian values ​​due to their simple operation and strong load carrying capacity. [0003] However, when the traditional multi-rotor drone is parked, the rotor is directly exposed, the cantilever is long, it cannot be folded, and it takes up a lot of space. It needs a special storage box and is not easy to carry; while the multi-rotor drone with foldable elements , due to the complexity of the folding mechanism, it is prone to mechanical failure. [0004] Therefore Chinese patent CN106081084B provides a kind of po...
