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 present invention relates to a rapid deployment and recovery device for AUVs under high sea conditions. The device includes: a V-shaped recovery frame: used to accommodate AUVs; an AUV guide component: installed in front of the V-shaped recovery frame to realize the approaching AUVs Guide; sling assembly: including the reel driving motor fixed on the bottom of the unmanned boat, the sling retracting and unwinding reel, and the V-shaped frame slings installed at the four corners of the V-shaped recovery frame respectively. The V-shaped frame sling passes through The drive motor controller commands to control the reel drive motor to realize the release and storage of the V-shaped frame sling; the blocking net component: installed between the 4 V-shaped frame slings to achieve side and rear protection and blocking to prevent the AUV from slipping out Outside the V-shaped recycling box. Compared with the prior art, the present invention has the advantages of expanding the recovery area, reducing the requirements for high-precision docking, rapid deployment and recovery, impact prevention, and safety protection.

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...
