A ship-based underwater glider deployment and recovery system and corresponding deployment and recovery methods

Abstract

The invention relates to launching and recycling technologies for underwater gliders or other underwater or water surface vehicles, in particular to an intelligent underwater robot shipborne launching and offshore recycling mechanism and corresponding method. The recycling mechanism comprises a shipborne body, a main recycling slide way, an auxiliary recycling slide way, an electric turning mechanism, an electric control cabinet, a tensioning mechanism, a multi-sensor fusion positioning system, a dragging unit and a hook system. The recycling mechanism is simple, reasonable, reliable in structure, and easy and convenient to operate, the underwater gliders, autonomous underwater vehicles (AUV), other underwater robots and the like can be launched and recycled quickly and efficiently, the workload of sailors and related staff on a ship are greatly relieved, the dangerous factors in the launching and recycling processes of the underwater robots are avoided, and the problem that the launching and recycling processes waste time and labor is solved.

Description

technical field [0001] The present invention relates to the technical field of deployment and recovery of underwater glider or cylindrical or rod-shaped underwater or surface vehicles, and also relates to the deployment and recovery method of the corresponding system. Background technique [0002] With the development of marine resources and changes in the situation of coastal defense, the area of ​​marine utilization has been expanding, and has continued to extend to the deep sea and the open sea. Scientists and researchers have begun to devote themselves to the research and application of underwater robots. At present, many different types of underwater robots have been applied to military marine technology, marine science and technology investigation, seabed exploration, pipeline maintenance, oil field exploration and other industries, such as underwater gliders, AUVs, ROVs, etc. [0003] Among them, the underwater glider is a new type of underwater robot. Because it uses...

AI Technical Summary

Problems solved by technology

[0004] However, due to the impact of sea wind and waves, underwater glider recovery has always been a worldwide problem, and the operation process is relatively difficult

At present, there are three main methods of recycling: ①Using floating dock type and lifting platform for underwater docking and recycling operations, although the impact of wind and waves can be reduced, but a dedicated support mother ship is required, and the cost of the dedicated mother ship and use is expensive, which is not suitable for the current domestic situation

②Using the mother ship to hoist and recover on the water surface generally requires staff to take a motorized boat close to the underwater robot to complete the docking with the recovery mechanism; this operation method is greatly affected by wind and waves, and equipment damage and personnel injury are prone to occur when the sea condition is poor

Similarly, this method is time-consuming and laborious, and is greatly affected by wind and waves. When the sea conditions are bad, the operation of the noose becomes extremely difficult

[0005] In addition, the deployment and recovery of other similar underwater gliders, such as cylindrical and rod-shaped underwater and surface vehicles, also have the above serious problems.
