A full-sea depth simulation test system for a seawater hydraulically adjustable ballast device

Abstract

The invention discloses a full-sea-depth working condition simulation test system of a seawater hydraulic adjustable ballast device, and belonging to the related field of submersibles; the test systemcomprises a control valve group, three hand pumps, a three-plunger pump station and an open type water tank, wherein the control valve group is formed by integrating a plurality of valves; the control valve group comprises a plurality of stop valves, a port I and a port II are formed in the integrated control valve group; the port I is connected with the open type water tank; the port II is connected with an outlet of the three-plunger pump station; the three hand pumps are respectively a first hand pump, a second hand pump and a third pressure pump; each stop valve is controlled to be openedand closed through the first hand pump and the second hand pump, the three-plunger pump station and the third hand pump are adopted to simulate the marine environment, the first hand pump and the second hand pump are adopted to simulate a hydraulic source, and the open type water tank is adopted to simulate the ballast water tank and provide a water source for the three-plunger pump station. According to the system, various experimental data can be conveniently obtained, and reliable guidance is provided for the actual seawater hydraulic adjustable ballast device to work under the sea.

Description

technical field [0001] The invention belongs to the field related to submersibles, and more specifically relates to a simulation test system for full-sea deep working conditions of a seawater hydraulically adjustable ballast device. 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 a...
