Remote-controlled UUV distributing and recovering mechanism and method capable of automatically hooking and unhooking

Abstract

The invention provides a remote-controlled UUV distributing and recovering mechanism capable of automatically hooking and unhooking. The distributing and recovering mechanism comprises a lifting hookdevice, a hook device and a remote controller, back part and bottom part of the lifting hook device are provided with a convex annular structure respectively, the back annular structure is used for being connected with a crane lifting belt, the bottom annular structure is used for being connected with an UUV, the tail part comprises two propellers which are symmetric about a center line of the tail end, the remote controller can control the propellers to push the lifting hook device, so that the lifting belt is dragged to move on the water surface through the lifting hook device; the hook device comprises an electric telescopic rod, the remote controller controls the electric telescopic rod to stretch out or contract so as to complete the unhooking action or the hooking action; a transverse U-shaped groove for allowing the lifting hook device to enter and a limiting plate for auxiliary hooking are contained in the back part of the UUV. The mechanism is mainly characterized in that a submerged worker is not required to be matched with a hook and unhooking, so that personal safety of the submerged worker caused by collision of the lifting hook and the submerged worker under the action of stormy waves is avoided; and the mechanism is simple and convenient to use, and the distributing and recovering efficiency of the UUV is improved.

Description

technical field [0001] The invention relates to a remote-controlled UUV deployment and recovery mechanism and method capable of automatic hooking and uncoupling, and belongs to the field of UUV deployment and recovery on water surfaces. Background technique [0002] The deployment and recovery of UUV is an essential step in its operation process, and the successful deployment and recovery is the basis for UUV to work normally underwater. Looking at the research status at home and abroad, the traditional deployment and recovery methods mainly include single-point hanging deployment and recovery, A-frame deployment and recovery, single-arm deployment and recovery, and slideway deployment and recovery. Among them, slideway deployment and recovery It needs to be used in conjunction with slideways, winches, control systems, etc., which takes up a large space and is complicated to operate; however, there are several recovery methods such as single-point lifting deployment recovery...

Problems solved by technology

Looking at the research status at home and abroad, the traditional deployment and recovery methods mainly include single-point hanging deployment and recovery, A-frame deployment and recovery, single-arm deployment and recovery, and slideway deployment and recovery. Among them, slideway deployment and recovery It needs to be used in conjunction with slideways, winches, control systems, etc., which takes up a large space and is complicated to operate; however, there are several recovery methods such as single-point lifting deployment recovery, A-frame deployment recovery, and single-arm deployment recovery. It occupies a small space, is easy to operate, and has good versatility, but it requires divers to cooperate with the operation. This kind of deployment and recovery method has a high probability of collision between the diver and the hook under harsh sea conditions, endangering the personal safety of the diver.

[0003] Check the domestic and foreign UUV deployment and recovery related documents and patent databases. Currently, the deployment and recovery of the hanging type requires the cooperation of divers to launch; for the single-point lifting device and method that does not require divers to launch, no relevant content has been retrieved.
