Multi-rotor unmanned plane

Abstract

The invention discloses a multi-rotor unmanned plane, and belongs to the technical field of an unmanned plane. The multi-rotor unmanned plane comprises a plane body, a plane arm, a motor, a rotor wing, 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 foot stool is arranged beneath the plane body; besides, a suspending rod is further arranged on the plane body, the upper end of the suspending rod is provided with a magnetic absorbing head; a suspending hook is further arranged on the suspending rod. In use, the multi-rotor unmanned plane can be absorbed and suspended on an iron object at a high place through the magnetic absorbing head on the suspending rod, or suspended on an electric wire in the air, branches and other objects through the suspending hook. The lifting force of the multi-rotor unmanned machine in a hanging state is not provided by power energy of the battery, thus the working time of an onboard working device can be prolonged greatly in a rising and landing process. The multi-rotor unmanned plane can be widely applied to overhead monitoring at a fixed point, monitoring, live telecast, environmental protection monitoring, case detection, urban administration, courtyard safeguard, vehicle anti-theft, express delivery, 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. , high-voltage lines, bridges, dams, road inspection, search and rescue, 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 to 30 minutes, that is to say, the working time of multi-rotor drones in the air is generally only 10-30 minutes, wh...
