The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle wing adjusting device and adjusting method, and provides the following scheme thatthe unmanned aerial vehicle wing adjusting device comprises an unmanned aerial vehicle body, four first take-off devices connected through hollow pipes are arranged on the unmanned aerial vehicle body, and second take-off devices are arranged on the hollow pipes; each first take-off device comprises a rotating motor and a rack, each hollow pipe is fixedly connected with a semi-cylindrical block,a through groove is formed in the end face of each semi-cylindrical block, a turbine and a connecting column are arranged in each through groove, each turbine is engaged with a worm, and one end of each connecting column extends to the outer portion of the bottom end of the corresponding semi-cylindrical block and is fixedly connected with a bevel gear; the bevel gears are engaged with semi-annular crown gears, output shafts of the rotating motors are fixedly connected with first rotors and rotating boxes, and the two sides of each rotating box are fixedly connected with telescopic rotor sheaths. When the unmanned aerial vehicle encounters hail, the purpose of preventing or reducing damage to the rotor wings of the unmanned aerial vehicle is achieved, and the risk of crash of the unmannedaerial vehicle is reduced.
本发明涉及无人机技术领域,尤其是一种无人机的机翼调节装置及调节方法,现提出如下方案,其包括无人机本体,无人机本体上设有四个通过空心管连接的第一起飞装置,空心管上均设有第二起飞装置,第一起飞装置均包括旋转电机和机架,空心管均固定连接有半圆柱块,半圆柱块端面均开设有通槽,通槽中均设有涡轮和连接柱,涡轮均啮合有蜗杆,连接柱的一端均延伸至半圆柱块的底端外部并固定连接有锥形齿轮,所处锥形齿轮均啮合有半环形皇冠齿轮,旋转电机的输出轴上均固定连接有第一旋翼和转动盒,转动盒的两侧均固定连接有可伸缩的旋翼护套。本发明达到了无人机在遇到冰雹时,避免或者减少无人机的旋翼受到损坏的目的,降低了无人机坠毁的风险。
