Autonomous laying, recycling and charging device for AUV (Autonomous Underwater Vehicle) under severe sea conditions

Abstract

The invention relates to an autonomous laying, recycling and charging device for an AUV (Autonomous Underwater Vehicle) under severe sea conditions. The device comprises an elliptic cylinder capturing cage, wherein the tail part of the elliptic cylinder capturing cage is opened, and an inner cavity is formed in the elliptic cylinder capturing cage; the device further comprises a capturing cage moving assembly which comprises a horizontal transverse guide rail erected at the bottom of an unmanned ship control platform and a steel cable winding and unwinding control mechanism which slides on the horizontal transverse guide rail to adjust the transverse position, and a capturing cage fixing assembly which comprises a vertical rod, a stable sleeve and a vertical rod locking clamp, the lower end of the vertical rod is fixedly connected with the elliptic cylinder capturing cage, the stable sleeve sleeves the vertical rod, the vertical rod locking clamp is fixedly connected with a steel cable winding and unwinding control mechanism; the device further comprises an AUV identification assembly which comprises an underwater lighting unit and an underwater visual sensor unit, and an AUV locking assembly which comprises a screw rod arranged in an inner cavity of the tail portion of the elliptic cylinder capturing cage and a locking buckle fixed to the screw rod. Compared with the prior art, the device has the advantages that the recoverable area is enlarged, the requirement for high-precision butt joint is lowered, and the collision risk of the bow portion during AUV recovery is lowered.

Description

technical field [0001] The invention relates to the field of autonomous underwater submersible recovery control, in particular to an AUV autonomous deployment recovery charging device under severe sea conditions. Background technique [0002] With the gradual progress of my country's ocean exploration and the continuous development of ocean technology, AUVs (autonomous underwater vehicles) are playing an increasingly important role in exploring the ocean and ensuring national security. Since the 21st century, marine scientific research, development and exploration engineering, and military applications have continuously put forward higher requirements for autonomous unmanned underwater vehicles. [0003] Although the working time and cruising range of AUVs under water are continuously improved, they are limited by the size of AUVs, the planning and layout of batteries, and the development of the battery industry itself. There are bound to be limits to optimizing AUV energy ...

Problems solved by technology

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 the wind, wave and current will have complex effects on the horizontal and vertical position and heading of the unmanned vehicle. As a result, it is difficult to perform high-precision docking betwe
