A UAV cooperative unmanned boat deployment and recovery system with parallel extension arms

Abstract

The invention discloses an unmanned aerial vehicle cooperative unmanned boat deployment and recovery system with parallel extension arms, which includes an unmanned aerial vehicle, a rhombic telescopic frame, a steering gear and a mechanical hook. The bottom of the unmanned aerial vehicle is connected to two The rhombic telescopic frame, the two rhombic telescopic frames form a parallel extension arm structure, the steering gear and the mechanical hook are all arranged at the bottom of the rhombic telescopic frame, and the steering gear is used to drive the two The up and down expansion and left and right translation of the diamond-shaped telescopic frame, the mechanical hook is used to hook the rectangular frame with the guide rope on the unmanned boat; the UAV with parallel extension arms provided by the invention cooperates with the unmanned boat The release and recovery system, through the precise control of the extendable robotic arm by the drone, can bring the guide rope back to the mother ship and assist in the recovery of the unmanned boat; it has the characteristics of easy operation, fast movement, reusability, and good safety. .

Description

technical field [0001] The invention relates to the technical field of robotic arms equipped with drones, in particular to a drone-coordinated deployment and recovery system for unmanned boats with parallel extension arms. Background technique [0002] At present, domestic and foreign deployment and recovery equipment and methods for unmanned boats mainly adopt some relatively traditional deployment and recovery methods. On the mother ship, slide the heavy hammer to the bell mouth along the guide rope to complete the docking with the unmanned boat. However, due to the influence of sea conditions, the high-pressure gas cylinder often leaks air, which makes the guide wire unable to eject to the mother ship, and the high-pressure gas cylinder can only fire two rounds at a time, which is inconvenient to use. [0003] Utilizing the good mobility and operability of the UAV, the parallel extension arm can be mounted under the UAV, and the mechanical hook of the parallel extension ...

Problems solved by technology

However, the range of use of the robotic arm is limited and it cannot perform many different tasks

[0008] 2) The publication number is CN105014687A, and the patent title is "a mechanical arm with a multi-rotor drone". In the patent document, the mechanical arm is connected under the multi-rotor drone. It is composed of a holder, which solves the problem that the robotic arm cannot freely operate at high altitude, but the operability of the robotic arm is not strong, and it cannot realize telescopic movement at any angle

However, the stability of the robotic arm is not good, and the grip is not firm enough
