Underwater submersible vehicle buoyancy adjusting device

Abstract

The invention belongs to the technical field of attitude and state control of underwater vehicles, and specifically provides a buoyancy adjustment device for underwater vehicles, including an adjustment cylinder, a piston assembly, a booster spring and a push rod assembly, and a middle hole is opened in the middle of one end surface of the adjustment cylinder , the other end face is connected with the push rod assembly, the piston assembly is built into the adjustment cylinder and the piston assembly is matched with the inner wall of the adjustment cylinder; the push rod assembly includes a motor, a timing belt, a screw rod and a cylinder, and one end of the cylinder is fixed to one end of the adjustment cylinder Connection, the screw rod is set in the cylinder and one end is connected to the motor through the timing belt, and the other end is connected to the piston assembly in the adjustment cylinder; the booster spring is set between the piston assembly and the end face of the adjustment cylinder connected with the push rod, and assists The spring is sleeved on the outer circumference of the lead screw. The buoyancy adjustment device of the underwater submersible increases the effective working depth of the buoyancy adjustment device without increasing the output power of the electric push rod assembly, thereby increasing the diving depth of the underwater submersible and realizing standardized production.

Description

technical field [0001] The invention relates to the technical field of attitude and state control of an underwater submersible, in particular to a buoyancy adjustment device for an underwater submersible. Background technique [0002] The buoyancy adjustment device is used to adjust the working state of the submersible when it floats up and dives, as well as its pitch and nose navigation attitude. The quality of its performance directly affects the navigation safety of the submersible. The current buoyancy adjustment is divided into adjustable ballast type and variable volume type according to the adjustment method. [0003] 1) Adjustable ballast buoyancy adjustment device [0004] Adjustable ballast type buoyancy adjustment device, that is, under the condition of constant volume, the net buoyancy can be changed by changing its own weight. This adjustment method has a strong adjustment ability and a wide range of buoyancy changes, and is mostly used for medium and large di...
