Underwater vehicle recovery device and recovery method

Abstract

The invention provides an underwater vehicle recovery device applied to an unmanned ship. The device comprises an unmanned ship end recoverer and an unmanned underwater vehicle end recoverer, whereinthe unmanned ship end recoverer and the unmanned underwater vehicle end recoverer are each provided with a magnet, an unmanned ship end mooring rope is arranged on a side, away from a corresponding magnet, of the unmanned ship end recoverer, an unmanned underwater vehicle end mooring rope is arranged on a side, away from the corresponding magnet, of the unmanned underwater vehicle end recoverer, and a propeller is arranged on a side surface of the unmanned ship end recoverer. The recovery device is advantaged in that an unmanned ship and a micro underwater vehicle release the respective recoverer connected by recovery cables, so positioning and navigation errors can be greatly allowed, when the unmanned underwater vehicle is emergently recovered due to propulsion faults, electronic circuitfaults and the like, the two recoverers are rapidly connected and matched through the electromagnets, the device is more efficient, whether butt joint of the recoverers at the end is successful or not is detected through a pressure sensor and a tension sensor, and the device is more efficient and rapid and has wide applicability in the field of unmanned underwater vehicle recovery.

Description

technical field [0001] The invention relates to the field of marine detection devices, in particular to the field of underwater vehicle recovery. Background technique [0002] Unmanned submersibles are unmanned, remote control or automatic control devices that navigate underwater. They mainly refer to intelligent systems that replace divers or manned small submarines for deep-sea exploration, lifesaving, and mine removal. . Therefore, unmanned underwater vehicles are also called "diving robots" or "underwater robots". Unmanned underwater vehicles can be divided into military and civilian use according to the application field. In the military field, unmanned underwater vehicles can be used as unmanned combat platform weapons in a new concept of weapons. In this sense, the role of an unmanned underwater vehicle is similar to that of a drone. In the civilian field, it can replace divers in salvage of sunken ships, deep water exploration, and underwater cable laying and oth...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the technical problems of poor dynamic positioning performance and large underwater navigation error in the miniature submersibles in the prior art, which lead to low success rate and low efficiency of recovery of the miniature submersible by unmanned ships, the present invention provides a recovery method for submersibles. The device and recovery method abandon the traditional idea of ​​relying on the autonomous navigation and dynamic positioning of the micro-submersible to wait for the unmanned ship to recover the micro-submarine. The recovery device only needs the submersible to rely on inertial navigation or GPS navigation to roughly drive to the vicinity of the unmanned ship, which can greatly allow the error of positioning and navigation, improve the success rate of miniature submersible recovery, and greatly improve the efficiency. The field of submarine recovery has wide applicability
