A high-pressure buoyancy self-calibration device for deep-sea operation equipment

Abstract

The invention discloses a high-pressure-resistant buoyancy self-calibration device for deep-sea operation equipment, including a deep-sea high-pressure resistant cabin, a deep-sea high-pressure resistant column capsule, a telescopic adjustment and support mechanism for a high-pressure resistant column capsule, a power reciprocating stroke drive mechanism, etc.; The high-pressure column capsule is set at one end of the deep-sea hyperbaric capsule and communicates with the deep-sea hyperbaric capsule. The telescoping adjustment of the high-pressure column capsule is connected with the support mechanism, and the expansion and contraction of the telescopic adjustment and support mechanism of the high-pressure column capsule are controlled, thereby driving the expansion or contraction of the deep-sea high-pressure column capsule, and the volume changes. The power reciprocating stroke driving mechanism It is installed inside the deep-sea hyperbaric cabin. The invention realizes the mechanical micro-adjustment of the buoyancy drive system by designing a compact and light high-pressure-resistant column capsule telescopic adjustment and support mechanism and a power reciprocating stroke drive mechanism.

Description

technical field [0001] The invention relates to the technical field of buoyancy trimming of deep-sea operating equipment, in particular to a high-pressure-resistant buoyancy self-calibration device, which is suitable for underwater operating equipment that needs to perform buoyancy trimming when working in a deep-sea high-pressure environment. Background technique [0002] Human beings have never stopped exploring nature, and deep-sea exploration plays an important role in the study of oceanic metal mineral resources, the origin of life on Earth, and extreme ecosystems. [0003] In modern marine survey equipment, deep-sea robots that traditionally rely on buoyancy drive mechanism to change the volume into motion power or rely on buoyancy for assisted motion account for the vast majority of marine survey equipment. Under the current marine technology, these two types of equipment are working Most of the previously used buoyancy trimming technology is one-time buoyancy trimmin...

AI Technical Summary

Problems solved by technology

Due to the large navigation depth, the operation period of diving and surfacing is long and relatively difficult, the sensitivity is poor, a lot of manpower and material resources are consumed, and there are still great technical defects:

However, there are two major technical problems in this mechanism: ① Since the change of buoyancy needs to rely on the oil circuit, high-pressure pump and high-pressure valve, the problem of large volume cannot be avoided; because the equipment is only an auxiliary buoyancy adjustment for underwater operation equipment, the volume The sheer size will inevitably bring about other balance issues

②Because the invention is only a single buoyancy adjustment device, when the deep-sea operation equipment needs multiple points, or even multiple three-dimensional points and surfaces for buoyancy compensation, since they are all scattered devices, firstly, the communication problem becomes extremely complicated. The problem caused by the separate detection and control of multiple devices is: either a separate control module needs to be set up to communicate with the underwater operation equipment, or the original control module of the underwater operation equipment must be used, which will inevitably increase the original system. The complexity of control is not conducive to the modularization and productization of equipment

③According to the actual sea test experience, since the outer skin used in this invention has folds and a cylindrical structure, this type of outer skin cannot withstand high pressure and the shape occurs in the direction perpendicular to the expected folds under a certain deep-sea pressure. The volume of the device itself is small, because the change of the shape of the outer skin has a great influence on the position of the center of buoyancy, which is not in line with the expected goal
