Abstract

The invention relates to supporting equipment for autonomous underwater vehicles, in particular to a modular buoyancy control unit for autonomous underwater vehicles. The modular buoyancy control unit comprises a carrier shell, a large end cylinder, a large end cylinder piston, small end cylinders, small end piston rods, a connecting plate, a driver, a motor, a hydraulic pump, an inner fuel tank and a hydraulic control valve. The large end cylinder is connected with the small end cylinders. The large end cylinder is communicated with seawater. The small end piston rods in the small end cylinders are connected with the large end cylinder piston in the large end cylinder. The motor, the hydraulic pump, the hydraulic control valve, the inner fuel tank and the driver are all mounted on the connecting plate. The hydraulic pump is communicated with the inner fuel tank and the hydraulic control valve. The hydraulic control valve is communicated with the small end cylinders on two sides of the small end piston rod. hydraulic oil entering the small end cylinders push the small end piston rods to drive the large end cylinder piston to compress; one end of the large end cylinder sucks or discharges the seawater with telescoping of the large end cylinder piston. The modular buoyancy control unit has the advantages such as small size, light weight and measurement accuracy.

Description

technical field [0001] The invention relates to ancillary equipment for autonomous underwater vehicles, in particular to a modular buoyancy regulating device for autonomous underwater vehicles. Background technique [0002] Autonomous underwater vehicle is an underwater platform that relies on its own energy for autonomous navigation, and has important application value. Autonomous underwater vehicles will be affected by various factors such as seawater depth, seawater temperature, seawater salinity, seasons, sea areas and other factors when navigating underwater, and the buoyancy of the vehicle will change, resulting in an imbalance between buoyancy and gravity. At this time, it is necessary to design a device for adjusting the buoyancy and gravity balance, that is, the buoyancy adjustment device, which can realize the automatic trimming of the autonomous underwater vehicle when navigating in different waters and different depths, so as to realize adaptive adjustment in dif...
