Recovery device for fixed-wing unmanned aerial vehicle

Abstract

The invention discloses a recovery device for a fixed-wing unmanned aerial vehicle. The device comprises a wind power generation device (1), a rectifying device (2), a control unit (3), an unmanned aerial vehicle recovery bin (4), a camera unit (5), an unmanned aerial vehicle storage chamber (7) and the like, and the wind power generation device (1) is used for generating wind energy, buffering an unmanned aerial vehicle, absorbing energy and reducing the speed; the rectifying device (2) is fixedly connected to the wind power generation device through screws and used for smoothing airflow and preventing turbulent flow; the control unit (3) adjusts the rotating speed of an axial flow fan of the wind power generation device (1) and the left-right and up-down swing angles of guide vanes (9) according to the flight attitude and speed, and applies wind resistance to the unmanned aerial vehicle; and a flow guide groove (11) and an air outlet (10) which are formed in the upper portion of the unmanned aerial vehicle recovery bin (4) apply wind power to the upper portion of the unmanned aerial vehicle, the unmanned aerial vehicle is forced to land, and finally the unmanned aerial vehicle is recovered into the unmanned aerial vehicle storage chamber (7). The recovery process is completed mainly by applying wind power to the unmanned aerial vehicle, the process is safe and reliable, the automation degree is high, and the device can be suitable for recovery of fixed-wing unmanned aerial vehicles in different fields.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to the field of recovery of fixed-wing unmanned aerial vehicles. Background technique [0002] At present, unmanned aerial vehicles (UAVs) have received widespread attention due to their advantages such as small size, low cost, flexible use, and the ability to be used as platforms in different fields. Among them, fixed-wing UAVs have the characteristics of fast flight speed, large battery life, and high maneuverability, and have been widely used in military, detection and other fields. Human-machine damage has brought serious restrictions to the use of fixed-wing UAVs. [0003] At present, the recovery methods for fixed-wing UAVs mainly include net impact recovery, parachute recovery, and landing roll recovery. [0004] For example: Chinese patent 201910532785 .X discloses a fixed-wing unmanned aerial vehicle recovery system, including a braking unit and a receiving unit. ...
