Multi-rotor unmanned aerial vehicle

Abstract

The invention provides a multi-rotor unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a fuselage, motors, rotors and foot frames. The motors are installed on the periphery of the fuselage. The rotors are connected to rotating shafts of the motors. The foot frames are arranged under the fuselage. In addition, transverse or longitudinal hanging rods are further arranged on the two sides of the fuselage or rotor protection frames. One ends of the hanging rods are provided with hooks, and the other ends of the hanging rods extend out of the rotor protection frames or the outsides of the rotor rotation ranges. The multi-rotor unmanned aerial vehicle can be hung or inserted into high objects to work through the hanging rods connected to the two sides of the fuselage or the rotor protection frames. The lifting force does not need to be provided by electric energy of a battery for the multi-rotor unmanned aerial vehicle in a hung or inserted state, and the working time of airborne working equipment in the one-time take-off and landing process can be greatly prolonged. The multi-rotor unmanned aerial vehicle can be widely applied in the fields of aerial fixed-point surveillance, monitoring, shooting, live broadcasting, environmental protection monitoring, field scientific investigation, case reconnoitering, city management, courtyard security and protection, vehicle theft prevention, express delivery 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. , High-voltage lines, bridges, dam inspections, search and rescue, express delivery, etc. 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 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 sa...
