Embodiment Construction

[0011] combine figure 1 , figure 2 , image 3 , a rope hook recovery device based on an elastic damping rope, the invention mainly consists of an upper elastic damping rope 1, a lower elastic damping rope 2, a recovery bracket 3, an upper beam 4, a lower beam 5, a bearing 6, and a rope 7 parts composition.

[0012] The elastic damping rope is the buffering body of the recovery system, mainly including an upper elastic damping rope 1 and a lower elastic damping rope 2 . The upper elastic damping rope 1 is used to absorb the recovered kinetic energy after the drone is captured, and the lower elastic damping rope 2 is also used to absorb the recovered kinetic energy after the drone is captured. One end of the upper elastic damping rope 1 is fixedly connected with the free end of the upper beam 4, and can be connected through a U-shaped ring transition through opening a hole on the upper beam, and the other end of the upper elastic damping rope 1 is connected with the upper en...

Abstract

The invention provides a rope hook recovery device based on an elastic damping rope, comprising an upper elastic damping rope, a lower elastic damping rope, a recovery bracket, an upper beam, a lower beam, an upper bearing, a lower bearing, a rope, and a water turbine damper . One end of the upper beam is rotatably connected to the recovery bracket through the upper bearing, the other end of the upper beam is connected to the recovery bracket through the upper elastic damping rope and the connection point is higher than the upper bearing, one end of the lower beam is rotatably connected to the recovery bracket through the bearing, and the lower beam The other end is connected with the recovery support through the lower elastic damping rope and the connection point is lower than the lower bearing. The two ends of the rope are respectively connected to the upper beam and the end of the lower beam away from the recovery support.

Description

technical field [0001] The invention relates to a drone recovery technology, in particular to a rope hook recovery device based on an elastic damping rope. Background technique [0002] Net crash recovery, parafoil recovery and crash rope recovery are fixed-point recovery methods. The first two need to add a high-precision guidance system to the airframe, and the foreseeable loss is high when the recovery fails. In comparison, the rope hook recovery method shows the best overall performance, and the limitation of terrain factors is small. It is not only suitable for ships with small deck space or even without a helicopter flight deck, but also can be used as a land-based UAV recovery device. Installed on the ground, in mountainous areas, on islands, or even in urban areas, it can be called an all-terrain recovery method, which has the characteristics of high mobility, high efficiency, and small footprint. [0003] At present, most of the collision rope recovery devices used...
