[0002] The gravity and buoyancy adjustment system is a key system for underwater submersibles to complete the floating and diving actions. It is also an important link to achieve rapid surfacing in emergency situations to ensure the safety of the submersible's navigation. The gravity and buoyancy adjustment system can adjust the submersible's own gravity or buoyancy. When the gravity of the submersible is greater than the buoyancy, the submersible dives, otherwise it floats. According to the working principle, it can be divided into the jettisoning type, the variable volume type, and the seawater suction and discharge type. Among them, the seawater suction and discharge type gravity and buoyancy adjustment system is often used in large submersibles as a means of gravity and buoyancy adjustment that can work in multiple cycles.

The C1 inlet of the stern high-pressure seawater pump device (11) is connected to the stern left auxiliary water tank (12), the C2 inlet of the stern high-pressure seawater pump device (11) is connected to the stern main water tank (10), the C3 inlet of the stern high-pressure seawater pump device (11) is connected to the stern right auxiliary water tank (9), and the C4 inlet of the stern high-pressure seawater pump device (11) is a sea outlet.

4. A high-pressure and low-pressure pump-coordinated large-capacity gravity buoyancy regulating system for large depths, low power consumption, and large capacity as claimed in claim 1, characterized in that: The bow low-pressure, high-flow seawater pump device (3) is provided with three water inlets, namely D1, D2 and D3, all of which have the functions of a water inlet and a water outlet. The D1 of the bow low-pressure, high-flow seawater pump device (3) is connected to the seawater outside the shipboard. The D2 of the bow low-pressure, high-flow seawater pump device (3) is connected to the stern low-pressure, high-flow seawater pump device (8) through the through-tank seawater pipe (13) and is used to lead to the stern main water tank (10). The D3 of the bow low-pressure, high-flow seawater pump device (3) is connected to the bow main water tank (4).
