Device for unmanned aerial vehicle to pull and release sleeve rope

Abstract

The invention discloses a device for an unmanned aerial vehicle to pull and release a sleeve rope. The purpose of the device is to reduce the control difficulty of the unmanned aerial vehicle to pulland release the sleeve rope. The device is provided with a movable trumpet-shaped guide rail, and the trumpet-shaped guide rail comprises spokes and foldable connecting objects connected between the spokes. The spokes are connected to supporting rods fixed to the lower portion of an unmanned aerial vehicle body through rotating shafts, and each spoke is connected with one supporting rod. One end of each spoke is connected to a driver, the drivers can drive the connected spoke ends to move up and down so that the spokes can rotate around the rotating shafts in a pitching manner, and therefore the horn-shaped guide rail is controlled to be opened and closed. When the unmanned aerial vehicle pulls the sleeve rope to fly, the horn-shaped guide rail is completely opened, the spokes are close tothe lower portion of the unmanned aerial vehicle body, and the sleeve rope is clamped around the supporting rods; when the unmanned aerial vehicle needs to be suspended above a specified object, thehorn-shaped guide rail is gradually folded, and the unmanned aerial vehicle is driven to move above the object under the counter-acting force generated when the horn-shaped guide rail is folded and collides with the object; and when the sleeve rope needs to be released, the trumpet-shaped guide rail is completely folded, and the sleeve rope slides down under the action of gravity.

Description

Technical field: [0001] The invention provides a device for hanging and dropping a noose for an unmanned aerial vehicle, which belongs to the field of safety engineering. Background technique: [0002] As the economy continues to develop and high-rise buildings continue to increase, the disaster risks associated with high-rise buildings, such as fire risks, are also increasing. When a high-rise fire occurs, a rope is erected between the roof of the fire high-rise building and the roof of the adjacent safe high-rise building to transport personnel and materials, which can play a positive role in the rescue of high-rise fires. Under normal circumstances, permanent ropes are not erected between the roofs of high-rise buildings, because permanently erected ropes are exposed to rain and sun for a long time, difficult to maintain, difficult to overhaul, and cannot be used safely during disaster rescue. Therefore, it is generally necessary to temporarily set up ropes between the r...
