Low-altitude flying unmanned aerial vehicle

Abstract

The invention provides a low-altitude flight unmanned aerial vehicle. The low-altitude flight unmanned aerial vehicle comprises a main body, a supporting arm is fixedly arranged on the outer side of the main body, and a propeller driven by a motor is arranged at the tail end of the supporting arm; an integrated circuit board is arranged in the main body; a center block is arranged at the bottom ofthe body, a bearing arc-shaped strip extending to the position below the supporting arm is arranged on the outer side of the center block, a buffer spring is arranged in the center block, and a roller bead extending to the position below the center block is movably connected to the bottom of the buffer spring; and an air inlet communicated with the cavity is formed in the side face of the main body, and a plurality of sets of air outlet pipes penetrating through the bottom of the main body are evenly arranged in the cavity. According to the low-altitude flying unmanned aerial vehicle, in thetakeoff and landing process of the unmanned aerial vehicle, the contact area between the four sets of bearing arc-shaped strips and the bottom face is uniform, so that the unmanned aerial vehicle is more stable in the takeoff and landing process, and the appearance of the unmanned aerial vehicle cannot deviate; and the air inlet, the cavity and the air outlet pipes form an air channel, so that theinfluence of air resistance on the flight of the unmanned aerial vehicle is effectively reduced.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a low-altitude flying unmanned aerial vehicle. Background technique [0002] Unmanned aircraft is referred to as "unmanned aerial vehicle", and the English abbreviation is "UAV". Man-machine is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned umbrella Wing aircraft, etc.; it has the advantages of small size, low cost, convenient use, and strong adaptability to the working environment; therefore, drones are increasingly used in various new fields, such as the inspection and maintenance of high-voltage lines. [0003] As a channel for power transmission, high-voltage lines require regular inspection / maintenance to ensure the safety of power transportation; in...
