Device and method for initiatively capturing unmanned underwater vehicle on water surface by unmanned ship

Abstract

The invention discloses a device and method for initiatively capturing an unmanned underwater vehicle on a water surface by an unmanned ship. The water surface unmanned ship, a recovery cage and an initiative capture control system are included. The water surface unmanned ship is of a double-body ship type, and an open cabin is arranged in the middle of a ship body. The recovery cage is used for capturing the unmanned underwater vehicle. The initiative capture control system is integrated in a shipborne computer of the water surface unmanned ship. The open cabin in the middle of the water surface unmanned ship is used for holding the recovery cage. The recovery cage is connected with the water surface unmanned ship through a hydraulic telescopic rod installed in the cabin. The hydraulic telescopic rod is connected with the initiative capture control system, the recovery cage is controlled by the initiative capture control system to be put into water or to be taken into the cabin, and the height of the collection cage is also adjusted precisely. The device and method has the beneficial effects that the unmanned ship and the recovery device and method thereof are provided, forced recovery can be conducted without the need for matching of the unmanned underwater vehicle, initiative capture of the uncontrollable unmanned underwater vehicle of an unknown source can be achieved, andimportant military application value is achieved.

Description

technical field [0001] The invention relates to a device and method for an unmanned ship to actively capture an underwater unmanned vehicle on the water surface, and belongs to the technical field of marine unmanned systems. Background technique [0002] As an advanced marine exploration platform, underwater unmanned vehicles have been widely used in marine scientific investigations, seabed exploration, military applications and other fields. After the underwater unmanned vehicle completes its mission, it usually needs to be recovered by the mother ship in the sea. However, due to the influence of sea waves and the flow field of the mother ship, there has always been a technical bottleneck that is difficult to break through in the surface recovery of the underwater unmanned vehicle. [0003] At present, there are mainly the following methods for the recovery of underwater unmanned vehicles: [0004] 1. Lifting and recycling on the water surface generally require staff to ta...

AI Technical Summary

Problems solved by technology

[0004] 1. Lifting and recycling on the surface of the water generally require staff to take a motorized boat close to the underwater unmanned vehicle to complete the docking with the recovery mechanism. This method is greatly affected by wind and waves, and it is prone to equipment damage and personnel safety hazards in bad sea conditions.

[0005] 2. The mother ship uses lifting slides or underwater docking devices for underwater docking and recovery operations, but underwater docking is difficult and demanding. The underwater unmanned vehicle needs to maintain real-time communication with the mother ship and constantly adjust its attitude to aim at the docking device. At the same time, the flow field of the mother ship will affect the movement of the underwater unmanned vehicle, which increases the difficulty of recovery

[0006] 3. By pulling the traction rope thrown by the underwater unmanned vehicle, use a special docking lifting device for docking and recovery. This method requires the underwater unmanned vehicle to adopt a specific rope throwing mechanism, which has large limitations and is not suitable for underwater use. Applicability issues for unmanned aerial vehicles

[0007] What is important is that the above main recovery methods are only for the recovery of underwater unmanned vehicles that are controllable by one's own side. At present, there is no active capture and recovery device and method for unknown sources and uncontrollable underwater unmanned vehicles.
