Combined system of unmanned ship and unmanned submersible

Abstract

A combined system of an unmanned ship and an unmanned submersible comprises the unmanned ship located on the water surface and the unmanned submersible located underwater. The unmanned ship and the unmanned submersible are connected through an umbilical cable. A power twisted pair for power supply and duration and a signal line for transmitting control signals and data signals are contained in the umbilical cable. An unreeling system for automatically reeling and unreeling the umbilical cable is arranged on the unmanned ship and comprises an unreeling winch used for twisting the umbilical cable, an unreeling steering engine for controlling the unreeling winch to rotate to reel and unreel the umbilical cable and an encoder for measuring the unreeling length. A butt joint berthing device is arranged between the unmanned ship and the unmanned submersible. By the adoption of the combined system, the umbilical cable is reeled and unreeled through the unreeling system, and the underwater locating accuracy is improved; the unmanned submersible and the unmanned ship can be in butt joint stably through the butt joint berthing device, the butt joint berthing device is driven by the unmanned ship to move on the water surface, and the navigation efficiency is improved; and when underwater observation is needed, the unmanned submersible can be automatically separated from the unmanned ship, and the launching depth of the unmanned ship is controlled through the unreeling system.

Description

technical field [0001] The invention relates to a combination system of an unmanned ship and an unmanned submersible. Background technique [0002] There are two common types of unmanned underwater vehicles: Remotely Operated Vehicles (ROV) and Autonomous Underwater Vehicles (AUV). The ROV obtains energy through the umbilical cable connected to the water surface, with sufficient power, the working time is not limited by energy, and the working efficiency is high. AUV relies on its own autonomous ability to manage and control itself to complete the assigned mission. It has a large range of activities, good mobility, high degree of intelligence, and strong autonomy. Both of the above-mentioned underwater robots have disadvantages: among them, ROV usually needs to be equipped with a mother ship, the mother ship and a series of staff have huge expenses, and the range of activities is limited; AUV is limited by its own energy, and its endurance is limited; and due to underwater ...
