Multi-rotor unmanned aerial vehicle

Abstract

The invention relates to a multi-rotor unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a vehicle body, enginearms, motors, rotors and a foot stool, wherein one ends of the engine arms are connected to the machine body, the motors are arranged on the engine arms, the rotors are arranged on rotating shafts ofthe motors, the foot stool is connected under the machine body, in addition, horizontal pipes are further arranged on the foot stool, telescopic hanging racks are arranged in the horizontal pipes andare inverted L-shaped or J-shaped, and locking devices used for locking the hanging racks are further arranged on the horizontal pipes. The multi-rotor unmanned aerial vehicle can be hung an object on high such as an enclosing wall of a high-rise rooftop, an advertising board, a traffic sign board, an aerial electric wire and branches in a propped or lifted mode through the hanging racks; and after being hung on the object on high in a propped or lifted mode, the multi-rotor unmanned aerial vehicle does not need to be provided with lift force by electric energy of a battery, and working equipment of the multi-rotor unmanned aerial vehicle can work or stand by on high for a long time. The multi-rotor unmanned aerial vehicle can be widely applied to the fields of aerial fixed-point shooting, monitoring, living broadcasting, environmental protection monitoring, case reconnoitre, urban management, courtyard security and protection, vehicle anti-theft 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. It is applied in dam inspection, search and rescue, express delivery and so on. 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 to 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 mult...
