Submersible buoyancy adjusting system

Abstract

The invention provides a submersible buoyancy adjusting system, which is characterized by comprising a variable ballast tank, a liquid level indicator, a first fluid-controlled cut-off valve, a second fluid-controlled cut-off valve, a third fluid-controlled cut-off valve, a fourth fluid-controlled cut-off valve, an oil tank, a one-way valve, a pressure-balanced valve, a safety valve, a high-pressure oil pump, a fifth fluid-controlled cut-off valve and a direct current motor.

Description

technical field [0001] The invention relates to a buoyancy adjustment system, in particular to a submersible buoyancy adjustment system for a full-sea deep manned submersible. Background technique [0002] At present, the scope of human understanding, research, and investigation of the ocean is mainly concentrated in the shallower than 6,500 meters. The so-called full sea depth refers to the entire depth range of the sea from 0 meters to the depth of 11,000 meters in the Mariana Trench, the deepest part of the ocean, and the full sea depth covers the trench area from 6,500 to 11,000 meters. [0003] After the submersible dives into the deep sea, affected by factors such as seawater density and the weight of samples collected by the submersible, the buoyancy and gravity balance of the submersible cannot be maintained. At this time, it is necessary to adjust the buoyancy of the submersible. In the usual adjustment method, for a submersible with a shallow depth, the water in ...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is that the high-pressure sea oil pump technology is very difficult, it is difficult to reach the full sea depth pressure (110MP first hydraulic control stop valve 3), the manufacturing cost is relatively high, and the service life and reliability are also limited by the limitation of seawater lubrication conditions. lower
