Abstract

The invention belongs to the technical field related to a submersible, which discloses a buoyancy regulation system based on a two-way seawater pump, The buoyancy regulating system comprises an adjustable ballast tank, two valve groups and a two-way seawater pump, wherein the two valve groups are a first valve group and a second valve group respectively; the two-way seawater pump is formed with anI port and an II port; the first valve group is connected with the adjustable ballast tank and the I port; the second valve group is connected with the II port and is communicated with seawater; Thebuoyancy regulation system adjusts the volume of sea water in the adjustable ballast tank adaptively through the positive and negative reversal of the two-way seawater pump, thereby realizing the buoyancy regulation; the valve group includes a one-way valve and balance valve connected in parallel; The one-way balance valve comprises a valve body, a one-way valve assembly and a balance valve assembly, wherein the one-way valve assembly and the balance valve assembly are respectively embedded at opposite ends of the valve body, and the one-way valve assembly and the balance valve assembly are mutually valve seats. The invention simplifies the structure, reduces the volume, and further reduces the complexity and cost of the buoyancy regulation system of the submersible.

Description

technical field [0001] The invention belongs to the technical field related to submersibles, and more specifically relates to a buoyancy adjustment system based on a bidirectional seawater pump. Background technique [0002] Submersibles are diving equipment with underwater observation and underwater operations. They are mainly used to perform tasks such as underwater surveys, seabed exploration, seabed development and salvage, lifesaving, etc., and can be used as an underwater operation base for divers. [0003] Submersibles need to adjust their buoyancy within a certain depth range in the ocean to hover at different depths to complete ocean surveys and ocean exploration tasks. In addition to actively controlling its buoyancy, after the submersible takes samples in the ocean, the weight will decrease due to the change of its own weight or the release of other equipment, and the change of seawater density due to changes in the physical and chemical properties of seawater wil...
