A device for hanging and dropping noose for drones

Abstract

A device for hanging and dropping a noose for an unmanned aerial vehicle. Its purpose is to reduce the difficulty of manipulating the UAV to hold and release the noose. The device of the present invention has a movable horn-shaped guide rail comprising spokes and collapsible links between the spokes. The spokes are connected to the poles fixed under the fuselage of the drone through rotating shafts, and each spoke is connected to a pole. One end of the spoke is connected to a driver. The driver can drive the connected spoke end to move up and down, so that the spoke can pitch and rotate around the rotation axis, thereby controlling the opening and closing of the trumpet-shaped guide rail. When the drone is flying with the rope, the horn-shaped guide rail is fully opened, and the spokes are close to the bottom of the drone body, and the rope is stuck on the periphery of the pole; when the drone needs to hover above the specified object, the horn-shaped guide rail gradually Collapse, the reaction force generated by collapsing and touching the object will drive the drone to move above the object; when the rope needs to be dropped, the horn-shaped guide rail is completely retracted, and the rope falls under the action of gravity.

Description

Technical field: [0001] The invention provides a device for hanging and dropping a rope for an unmanned aerial vehicle, belonging 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, also increase. When a high-rise fire occurs, a rope is erected between the roof of the 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 high-rise fire rescue. Under normal circumstances, permanent ropes are not erected between the roofs of high-rise buildings, because the permanently erected ropes are exposed to the rain and the sun for a long time, which is difficult to maintain and repair, and cannot guarantee the safety of use in disaster rescue. Therefore, it is generally necessary to temporarily erect a rope between the roofs o...
