The present invention belongs to the technical field of unmanned aerial vehicles, and specifically relates to a high-altitude unmanned aerial vehicle for placing advertisements, the high-altitude unmanned aerial vehicle for placing advertisements comprises an unmanned aerial vehicle body, a banner, a winding part, a pressure regulating part, and a torsion part, and a
storage tube is installed at the lower end of the unmanned aerial vehicle body. In the invention, when there is strong wind, the wind blows the banner, so that the banner drives the rotating shaft to move downward inside the
storage tube, so that the pressure regulating part is compressed by force, and when the banner drives the rotating shaft to move downward inside the
storage tube to trigger the winding part to run, the winding part drives the rotating shaft to rotate, so that the banner is stored inside the storage tube, so as to avoid the influence of the strong wind on the banner and further endanger the
flight safety of the unmanned aerial vehicle body, thereby improving the safety, and by adjusting the pressure regulating part, the wind blowing the banner can be adjusted to drive the pulling force of the rotating shaft to move inside the storage tube, and then the pulling force of the rotating shaft to move inside the storage tube when the wind blows the banner can be adjusted according to the banners of different sizes, thereby improving the adaptability.
