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; one end of 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 cross suspending frame is further arranged on the plane body, the outer end of the suspending frame is provided with a magnet and a bracket; the bracket is located beneath the magnet. The multi-rotor unmanned plane can be absorbed on an iron advertising board, a traffic signboard, a light pole, an outdoor air conditioning unit and other high objects through the magnet on the suspending frame. After absorbing on the high object, the lifting force of the multi-rotor unmanned machine in a hanging state is not provided by power energy of the battery, and the working devices on the multi-rotor unmanned plane can be worked or standby at the high place for a long time. 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, 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. 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...
