Device for stopping and recycling small-medium-sized unmanned aerial vehicles in air

Abstract

The invention discloses a device for stopping and recycling small-medium-sized unmanned aerial vehicles in air. The device is characterized by comprising a recycling frame with multiple energy absorption points, a buffer device with multiple energy absorption points, and a recycling and guiding device with software control and hardware equipment, wherein energy is impact energy; the recycling frame, the buffer device and the recycling and guiding device are organically combined to accomplish an unmanned aerial vehicle recycling process. Compared with an existing 'skyhook' recycling technology,according to the device provided by the invention, the recycling frame with the multiple energy absorption points is adopted to replace a recycling frame with a single energy absorption point, so that the occurrence of the risk that an unmanned aerial vehicle body is easy to damage since the unmanned aerial vehicles bears all impact energy is avoided, and the reliability and the safety in recycling the unmanned aerial vehicles are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle recovery, and in particular relates to a device for intercepting and recovering small and medium-sized unmanned aerial vehicles in the air. Background technique [0002] The recovery of small and medium drones is always a huge obstacle for drone applications. Due to their small size, light weight, and easy portability, small and medium-sized UAVs have been widely used in both civilian and military applications. Small and medium-sized UAVs are light in weight and have a low landing speed (less than 100 km / h). Compared with large UAVs, it should be easier to recover. There are many ways to recover them, such as parachuting, vertical landing, and sliding landing Etc. The specific methods are varied. Due to the large number and variety of small and medium-sized UAVs, the loss caused by landing and recycling is huge every year, even hundreds of them a year. This is a huge economic, sa...

Problems solved by technology

[0004] Due to the mutual friction between the recovered drone's wing suspension and the nylon rope to hook the aircraft, it will inevitably cause the drone to rotate and slide around the nylon rope, which is very easy to damage the drone's wing components and structure , it can be seen from the figure that even if the recovery is successful, the damage rate is quite large

[0005] If the nylon rope does not hit the end of the wing accurately during the recovery process, but hits the root of the wing or the wing part close to the fuselage, the drone cannot be rotated around the nylon rope in time and passed around by the drone itself. The rotation of the nylon rope buffers the huge impact force, so for a UAV with a weight of tens of kilograms and a speed of 50-100 km / h, the impact force on the wing is enough to damage its wing, and the accident is fatal
