Embodiment

[0044] The deployment and recovery of AUVs under high sea conditions mainly face two challenges. First of all, the random dynamic changes of sea waves and currents will have complex effects on the horizontal and vertical position and heading of the AUV, and wind, wave and current will have complex effects on the horizontal and vertical position and heading of the unmanned vehicle. The result of these comprehensive effects makes it difficult to carry out high-precision docking between unmanned vehicles and AUVs. The recovery method needs to allow as large a tolerance margin as possible for positioning deviations. Second, the recovery of AUVs is limited by several factors. Since the AUV's payload is mounted on the bow, it is easily damaged by impact; a typical AUV often has a dorsal fin, and the tail has a propeller in addition to the tail. Therefore, the recovery method also requires special consideration for the protection of the bow, dorsal fin and empennage.

Abstract

The invention relates to an AUV rapid distributing and releasing recovering device under high sea conditions. The device comprises a V-shaped recovering box, an AUV guiding assembly, a sling assembly,and a stopping net assembly, wherein the V-shaped recovering box is used for storing an AUV; the AUV guiding assembly is mounted at the front portion of the V-shaped recovering box and used for achieving guiding of the near AUV; the sling assembly comprises a drum driving motor fixed at the bottom of an unmanned ship, a sling retracting and deploying drum and V-shaped frame slings correspondinglymounted at the four corners of the V-shaped recovering box, and the V-shaped frame slings control the drum driving motor to achieve releasing and retracting storing of the V-shaped frame slings through a driving motor controller instruction; and the stopping net assembly is mounted among the four V-shaped frame slings and used for achieving protecting stopping of the side surface and the back surface, and the fact that the AUV slides out of the V-shaped recovering box is avoided. Compared with the prior art, the AUV rapid distributing and releasing recovering device has the advantages that the recovery area is expanded, the requirement of high-precision docking is reduced, rapid deploying and retracting recovery is achieved, collision is prevented, and the safety protection is achieved.

Description

technical field [0001] The invention relates to the field of AUV deployment and recovery, in particular to an AUV rapid deployment and recovery device under high sea conditions. Background technique [0002] As my country attaches great importance to the protection of marine rights and interests, AUVs (autonomous underwater vehicles) play an increasingly important role in exploring the ocean, developing and utilizing marine resources, and ensuring national security. [0003] The deployment and recovery of AUV is an essential part of the use process, and it is very important to improve the operating capability and endurance of AUV. Among them, the recovery of AUV, especially the difficulty of use, is a hot issue in this field of research. [0004] At present, most of the deployment and recovery of AUVs in the world are based on manned mother ships, which are highly dependent on manual operation. However, in complex and dangerous environments, there is an urgent need for unma...
