Technical Field
The invention relates to the field of recovery of small-sized fixed-wing unmanned aerial vehicles.
Background
In the unmanned aerial vehicle collision line recovery process, the success rate of unmanned aerial vehicle collision line hanging directly determines the success rate of unmanned aerial vehicle recovery. The top hook device is installed on the unmanned aerial vehicle and mainly comprises an onboard top hook and a high-reliability quick locking device. The top hook is used for interacting with the stopping rope, and the deceleration and final stability of the unmanned aerial vehicle are achieved. The existing top hook device is easy to cause the phenomenon of 'unhooking', and an unmanned aerial vehicle after being captured is easy to generate great attitude change, so that the stability of the capturing process is poor. Therefore, it is desirable to provide a hook device that can be quickly captured to avoid "unhooking" and the like, and that can improve the recovery success rate of the drone.

The invention aims to solve the problems that a top hook device on the existing unmanned aerial vehicle is easy to be unhooked and the stability of the capturing process is poor. The invention provides a double-hook device for recovering a collision line of an unmanned aerial vehicle.
A double hook device for recovering collision lines of an unmanned aerial vehicle is characterized in that a body of the double hook device is of an L-shaped structure, and the L-shaped structure comprises a hook rod and two hooks; the two hooks are arranged in the same plane, and a bent part is formed between each hook and the hook rod; the included angle between the two hooks ranges from 30 degrees to 80 degrees;
a hinge is fixed on the hook rod, and a No. 1 limiting blocking piece is hinged on the hinge;
every couple all is fixed with the hinge on all, and articulated on this hinge have No. 2 spacing separation blades, and two No. 2 spacing separation blades, No. 1 spacing separation blade and flexion enclose into the lock larynx chamber.
Preferably, the angle between the two hooks is 60 degrees optimally.
Preferably, the No. 1 limiting blocking piece and the No. 2 limiting blocking piece both use a hinge where the 1 limiting blocking piece and the No. 2 limiting blocking piece are located as an axis, and rotate towards the inside of the throat locking cavity, and the 1 limiting blocking piece and the No. 2 limiting blocking piece are limited at two end faces of the throat locking cavity.
Preferably, the hook stem is smooth in surface.
Preferably, the curvature of the curved portion is in the range of 20 ° to 75 °.
Preferably, the curvature of the curved portion is optimally 60 °.
The double-hook device for recovering the collision line of the unmanned aerial vehicle is mainly used for interacting with the blocking rope to realize the deceleration and final stabilization of the unmanned aerial vehicle. In order to ensure that the double-hook device and the blocking rope cannot be unhooked after being impacted, the blocking rope is quickly captured through the throat locking cavity. The lock throat cavity has the effect of catching the blocking rope, and the lock throat cavity can realize quickly catching the blocking rope to avoid unhooking, and also has a certain moving space in the lock throat cavity, and the lock throat cavity has certain damping to avoid the large attitude change of the unmanned aerial vehicle after catching. The hook is designed into a double-hook form, and compared with a single-hook form, the hit rate of the hook capturing and blocking rope can be improved.

Detailed Description
The first embodiment is as follows: the embodiment is described with reference to fig. 1, and the double-hook device for recovering the collision line of the unmanned aerial vehicle has an L-shaped structure, wherein the L-shaped structure comprises a hook rod 1 and two hooks 3; the two hooks 3 are in the same plane, and a bent part 5 is formed between each hook 3 and the hook rod 1; the included angle between the two hooks 3 ranges from 30 degrees to 80 degrees;
a hinge 4 is fixed on the hook rod 1, and a No. 1 limit catch 2-1 is hinged on the hinge 4;
each hook 3 is fixed with a hinge 4, and the hinge 4 is hinged with a No. 2 limit catch 2-2; and the two No. 2 limiting blocking pieces 2-2, the No. 1 limiting blocking piece 2-1 and the bending part 5 surround to form a throat locking cavity 6.
Each hook 3 forms an L-shaped structure with the hook stem 1, each L-shaped structure having a curved portion 5.
In a specific application process of the embodiment, the double-hook device for recovering the collision line of the unmanned aerial vehicle is arranged on the unmanned aerial vehicle and is mainly used for interacting with the blocking rope to realize the deceleration and final stabilization of the unmanned aerial vehicle.
When the blocking rope slides along the surface of the hook rod 1 and is contacted with the No. 1 limiting blocking piece 2-1, the blocking rope can push the No. 1 limiting blocking piece 2-1 to rotate towards the throat locking cavity 6 by taking the hinge 4 where the blocking rope is located as an axis. After the arresting rope enters the throat locking cavity 6, the No. 1 limiting baffle 2-1 is restored to the original state, the arresting rope is locked in the throat locking cavity 6, and the arresting rope is locked by the double-hook device.
