Multi-rotor-wing unmanned aerial vehicle

Abstract

The invention provides a multi-rotor-wing unmanned aerial vehicle. The multi-rotor-wing unmanned aerial vehicle comprises a vehicle body, vehicle arms, motors, rotor wings and a foot stand, the vehicle arms are connected to the vehicle body, the motors are mounted on the vehicle arms, the rotor wings are connected to rotary shafts of the motors, and the foot stand is arranged on the lower portion of the vehicle body. In addition, a detachable protective frame is further arranged on the vehicle body or the vehicle arms of the multi-rotor-wing unmanned aerial vehicle. In the vertical direction, the peripheral outline of the protective frame is larger than the rotating range of each the rotor wing. A hanging rope is further connected to the protective frame, the hanging rope passes through the outer edge of the protective frame and hangs, and a hook is connected to the tail end of the hanging rope. The multi-rotor-wing unmanned aerial vehicle can be hung at an object of a high position through the hanging rope and the hook. After being hung at the object of the high position, work equipment carried on the multi-rotor-wing unmanned aerial vehicle can work or be on standby at high positions for a long time. The multi-rotor-wing unmanned aerial vehicle can be widely applied to the fields of aerial fixed-point surveillance, monitoring, shooting, environmental protection monitoring, city management, courtyard security and protection, vehicle burglary prevention, animal scientific research and the like.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle. Background technique [0002] Multi-rotor drones usually have 3 to 8 rotors, especially 4 rotors are the most common. Multi-rotor drones have functions such as vertical take-off and landing, hovering in the air, low-speed flight, inverted flight, side flight, and 360-degree rotation. , Express delivery and other aspects have been applied. Existing multi-rotor UAVs mainly have the following disadvantages: due to relying on the batteries loaded on the machine to provide electric energy when hovering in the air, the battery life is short, and most multi-rotor UAVs that rely on battery power to work can only continue to fly at a time About 10-30 minutes, that is to say, the working time of multi-rotor drones in the air is generally only 10-30 minutes, which is far from satisfying people's use of multi-rotor drones for long-ter...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a multi-rotor UAV that can stay at a high place for a long time to work or stand by, so as to solve the shortcomings of the existing multi-rotor UAVs such as short space time and inability to work in the air for a long time.
