Embodiment Construction

[0017] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , figure 2 , image 3 , The multi-rotor UAV of the present invention includes a fuselage (1), a motor (2), a rotor (3), a rotor protection frame (4), and a tripod (5) in terms of mechanical structure. The motor (2) is installed on the periphery of the fuselage (1). The rotor (3) is connected on the rotating shaft (or on the speed changer) of the motor (2). The rotor protection frame (4) is positioned at the periphery of the rotor and plays the role of protecting the rotor. The tripod (5) is arranged under the fuselage (1). A pan / tilt, camera (6) or other working equipment and components are usually arranged under the fuselage, and a battery and a flight control unit are also installed in the fuselage (1). In addition, a connector (8) is provided on the rotor protection frame (4), and the hanging rod (7) is connect...

Abstract

The invention provides a multi-rotor-wing unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The multi-rotor-wing unmanned aerial vehicle comprises a vehicle body, motors, rotor wings and a foot stand, the motors are mounted on the periphery of the vehicle body, 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. The multi-rotor-wing unmanned aerial vehicle is characterized in that hanging rods are further arranged on the two sides of the vehicle body or on rotor-wing protective frames, one ends of the hanging rods are provided with hooks, magnets are arranged at the other ends of the hanging rods, and the multi-rotor-wing unmanned aerial vehicle can be hung at an object of a high position for working through the hooks on the hanging rods or attraction force of the magnets. The multi-rotor-wing unmanned aerial vehicle which is in a hanging state does not need battery electric energy for providing of lift force, and the work time of airborne work equipment can be greatly prolonged in the one-time taking-off and landing process. The multi-rotor-wing unmanned aerial vehicle can be widely applied to the fields of aerial fixed-point surveillance, monitoring, shooting, live broadcasting, environmental protection monitoring, field science investigation, case scout, city management, courtyard security and protection, vehicle burglary 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...
