Deep sea operation level ROV adjustable buoyancy system

Abstract

The invention relates to the field of deep sea operation, in particular to a deep sea operation level ROV adjustable buoyancy system, which comprises a buoyancy body and a buoyancy module, a groove is formed in the buoyancy body, and the buoyancy module is detachably installed in the groove. The buoyancy device has the beneficial effects that the groove can be formed in any position of the buoyancy body, the buoyancy module is installed at any position of the buoyancy body accordingly, so that the buoyancy applying position of the buoyancy body is changed; in addition, the density of the buoyancy body and / or the buoyancy module can be changed by changing the material of the buoyancy body and / or the buoyancy module, so that the buoyancy of the buoyancy body is changed. Further, the buoyancy magnitude and the buoyancy applying position of the buoyancy body can be adjusted through the shape and the size of the buoyancy module and / or the groove, and therefore it is guaranteed that the ROV is in a zero-buoyancy balance state underwater. The structure is simple, the buoyancy module is convenient to install, a traditional oil way buoyancy adjusting system is not needed, cost is saved, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to the field of deep-sea operations, in particular to a deep-sea operation-level ROV adjustable buoyancy system. Background technique [0002] Deep-sea scientific investigation and resource development are inseparable from advanced technology and equipment. At present, scientific research and operations in the deep-sea field mainly rely on deep-sea operation-level heavy-duty ROV (Remotely Operated Vehicle Remotely Operated Vehicle), which is used for underwater observation and inspection. And operating underwater robots), which have a large operating depth and long operating time, can resist relatively harsh marine environments, and are widely used in marine geological and biological investigations, auxiliary laying of submarine optical cables and pipelines, deep-sea rescue and salvage, underwater Monitoring and inspection of structures and other fields. [0003] The main frame of the deep-sea operation-level ROV is made of metal...

AI Technical Summary

Problems solved by technology

After the metal frame is equipped with different underwater operation equipment, its center of gravity will change, which requires a variable buoyancy system to balance this change and ensure that the ROV is in a balanced state during underwater operations. Currently, there is no variable buoyancy system. buoyancy system
