Unmanned aerial vehicle hovering in air through telescopic frame and control method

Abstract

The invention relates to an unmanned aerial vehicle hovering in air through a telescopic frame and a control method. when an unmanned aerial vehicle carries out operation, a gas with density lower than air density is inflated into a balloon located above the unmanned aerial vehicle body; a first motor is controlled to enable a first rotating shaft to rotate; the telescopic frame sinks, penetratesthrough a vegetation opening and is propped open; vegetation below the unmanned aerial vehicle body is hooked; the unmanned aerial vehicle is prevented from being blown away by wind, which means thatthrough a lifting force provided by a balloon and hooking between the unfolded telescopic frame and the vegetation below the unmanned aerial vehicle body, hovering of the unmanned aerial vehicle is realized, at the moment, a rotating speed of the rotor wings of the unmanned aerial vehicle body can be reduced or stopped to save an electric quantity, and long-time hovering of the unmanned aerial vehicle is achieved; and therefore enough hovering time is provided for enabling the unmanned aerial vehicle to complete operation, and when operation is completed, the telescopic frame is controlled tobe closed to be disengaged from hooking of vegetation, the rotor wings are started, the balloon is deflated, and re-flying is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an aerial hovering unmanned aerial vehicle and a control method through a telescopic frame. Background technique [0002] With the development of drone technology, drones will play an increasingly important role in various industries and fields at home and abroad, and have broad application prospects. At present, due to the limited capacity of the battery of drones, As a result of the duration of the drone's battery life, when the drone is operating in a certain area, such as shooting, the rotor of the drone must continue to rotate to ensure that the drone can hover in the area and perform operations. However, due to the continuous rotation of the rotor, the power in the battery will continue to decrease, so that the drone cannot stay for a long time and cannot guarantee the completion of the operation.

[0002] With the development of drone technology, drones will play an increasingly important role in various industries and fields at home and abroad, and have broad application prospects. At present, due to the limited capacity of the battery of drones, As a result of the duration of the drone's battery life, when the drone is operating in a certain area, such as shooting, the rotor of the drone must continue to rotate to ensure that the drone can hover in the area and perform operations. However, due to the continuous rotation of the rotor, the power in the battery will continue to decrease, so that the UAV cannot stay for a long time and cannot guarantee the completion of the operation.
