The invention discloses a high-pressure resistant buoyancy self-calibration device for deep sea operation equipment. The device comprises a deep-sea high-pressure-resistant cabin, a deep-sea high-pressure-resistant column bag, a high-pressure-resistant column bag telescopic adjusting and supporting mechanism, a power reciprocating travel driving mechanism, etc. The deep-sea high-pressure resistantcolumn bag is arranged at one end of the deep-sea high-pressure resistant cabin, and communicates with the deep-sea high-pressure resistant cabin, a telescopic adjust and supporting mechanism of thathigh-pressure-resistant cylinder sac is arrange inside the high-pressure-resistant cylinder sac of the deep sea, a power reciprocating stroke driving mechanism is connected with a high-pressure-resistant column bag telescopic adjusting and supporting mechanism through a stroke connecting rod, a telescopic adjust mechanism and a support mechanism of that high-pressure resistant cylinder bag are controlled to carry out extension and contraction action action, thereby driving the high-pressure resistant cylinder bag to expand or contract in the deep sea, and the volume is chan. The power reciprocating travel driving mechanism is arranged inside the high-pressure resistant cabin in the deep sea. The invention realizes the mechanical micro-adjustment of the buoyancy driving system by designinga compact and lightweight high-pressure-resistant column bag telescopic adjusting and supporting mechanism and a power reciprocating stroke driving 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
