Underwater docking, recycling and laying device for AUV

Abstract

The invention relates to an underwater docking, recycling and laying device for an AUV. The device comprises a carrying cylinder, wherein a guiding ring and a water suction ring are respectively, coaxially and fixedly connected to two ends of the carrying cylinder, and the other end of the water suction ring is covered with an openable-closable cover body; the ring wall of the guiding ring is a hollow shell, two ends of the outer wall of the ring wall are respectively bent towards the inside of the guiding ring and axially extend along the guiding ring to form a throat tube segment and a condensation segment, a wide opening end of the condensation segment faces to the carrying cylinder, a narrow opening end of the condensation segment sleeves and laminates on the outer part of a narrow opening end of the throat tube segment, a radial gap is formed between the two narrow opening ends so as to communicate an inner cavity of the hollow shell with an inner cavity of the guiding ring; an inner cavity of the water suction ring is communicated with the inner cavity of the hollow shell through a pipeline, and a water pump is arranged on the pipeline; and a locking mechanism and a limiting mechanism are arranged on the inner wall of the carrying cylinder and are respectively used for locking and limiting AUV. According to the underwater docking, recycling and laying device, the underwater docking, recycling and laying of the AUV can be safely, reliably and efficiently finished.

Description

technical field [0001] The present invention relates to the technical field of underwater operation devices, in particular to an underwater carrying platform applied to an autonomous underwater unmanned vehicle ("AUV" for short), in particular to an autonomous underwater unmanned vehicle on an underwater carrying platform. Recovery of docked and deployed devices. Background technique [0002] AUV is mainly used in the application fields of deep sea exploration such as marine scientific investigation, seabed exploration, seabed salvage and so on. Since the AUV's battery life and underwater operation time are limited by its own energy, when the AUV completes a certain task, it usually needs to be docked underwater and recovered to the carrying platform to replenish energy and command information. When the AUV receives the next After the mission, the AUV can be deployed underwater to carry out detection and operation tasks. [0003] At present, there are mainly three ways of ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly three ways of docking and deploying AUVs and underwater platforms: the first is to install a docking mechanism on the bow of the AUV to capture guiding targets such as ropes and rods, and the AUV moves along the guiding device and completes the docking. The first type is equipped with a docking device with a complex structure, poor fitability on various platforms, and requires major changes to the AUV, which affects navigation and operational performance; the second type is based on a conical guide cover, a horn and a cage This kind of docking method is the docking method of the docking target. This method has strict requirements on the maneuverability, motion control performance and aco
