Multi-rotor unmanned aerial vehicle

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a body, arms, motors, rotors, protection frames, scaffolds and the like and is characterized in that a hanging bracket is further arranged on the body and comprises a hook, a hanging rod, a base and rotating shafts, wherein the hook is arranged at the upper end of the hanging rod, the base is arranged at the lower end of the hanging rod, the rotating shafts are arranged on the base and located in the clamping positions of the body, and the hanging bracket can rotate around the rotating shafts. During use, the multi-rotor unmanned aerial vehicle can be hung on an object in a high position through the hook on the hanging bracket. The multi-rotor unmanned aerial vehicle in the hanging state doesn't need battery power for supplying lift force, and the working time of airborne working equipment in a take-off and landing process can be prolonged greatly. The multi-rotor unmanned aerial vehicle can be widely applied to the field of fixed point monitoring in the air, surveillance, shooting, environmental monitoring, field scientific investigation, case reconnaissance, city management, courtyard security and protection, vehicle guard, express transportation 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 9 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, dams and road 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 f...
