Abstract

The invention provides a maneuvering type unmanned aerial vehicle recovery device, and belongs to the technical field of unmanned aerial vehicle recovery. The maneuvering type unmanned aerial vehicle recovery device comprises a blocking assembly, a U-shaped part, a lifting hydraulic cylinder, a support, a rotation base, an upper supporting hydraulic cylinder, a lower supporting hydraulic cylinder and a carrier. After an unmanned aerial vehicle rapidly rushes at the vertically unfolded blocking assembly at a certain recovery speed, the unmanned aerial vehicle pushes a blocking pulley to move forwards together, a pulling rope which is connected to the lower end of the blocking pulley surrounds a pulley block and pulls a damper piston rod in a damper cylinder body, the kinetic energy of the unmanned aerial vehicle and the blocking pulley is quickly absorbed, and therefore the purposes that the unmanned aerial vehicle and the blocking pulley are decelerated and stopped within a quite short period, and finally the unmanned aerial vehicle lands, is buffered by a belly buffering part, and is supported and recovered in a frame of the blocking assembly are achieved. By the adoption of the maneuvering type unmanned aerial vehicle recovery device, an undercarriage or a recovery parachute or a hooking rope device does not need to be additionally installed on the unmanned aerial vehicle, the quantity of loaded oil of the unmanned aerial vehicle can be increased, the flight resistance of the unmanned aerial vehicle can be reduced, and therefore the cruising time of the unmanned aerial vehicle is prolonged, and the flight speed of the unmanned aerial vehicle is increased.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle recovery, in particular to a mobile unmanned aerial vehicle recovery device. Background technique [0002] At present, the recovery methods of fixed-wing UAVs mainly include landing gear landing roll recovery, parachute recovery, and crash rope recovery. Using the landing gear to land and slide, parachute or hit the rope to recover the UAV requires the UAV to be equipped with a landing gear, or to install a recovery umbrella in the fuselage, or to install a hook rope device on the UAV, resulting in a reduction in the size of the UAV. payload, and the additional protrusions on the fuselage increase the flight resistance of the drone. Contents of the invention [0003] The mobile unmanned aerial vehicle recovery device provided by the present invention realizes the arresting function of the unmanned aerial vehicle at high speed by installing an arresting component with a simple st...
