Multi-rotor unmanned plane

Abstract

The invention discloses a multi-rotor unmanned plane, which comprises a plane body, a plane arm, a motor, a rotor wing, a rotor protecting frame, and a foot stool; the plane arm is connected to the plane body, and the motor is installed on the plane arm; the rotor wing is connected to a rotary shaft of the motor, and the rotor protecting frame is arranged at the periphery of the rotor wing; the foot stool is arranged beneath the plane body. Besides, a suspending rope is further arranged on the multi-rotor unmanned plane; the front end of the suspending rope is connected to the plane body, and the plane arm or the rotor protecting frame; the tail end thereof is connected with a suspending hook. When the multi-rotor unmanned plane is under a hovering state, the suspending hook is hung under the multi-rotor unmanned plane. The multi-rotor unmanned plane is hung on an object at a high place through the suspending rope and the suspending hook. After hanging on the object at high place, the working devices on the multi-rotor unmanned plane can work or be standby at the high place for a long time. The multi-rotor unmanned plane can be widely applied to overhead monitoring at a fixed point, monitoring, shooting, environmental protection monitoring, urban administration, courtyard safeguard, vehicle anti-theft, animal scientific research, and other domains.

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.
