Abstract

The invention provides a manless underwater vehicle. The manless underwater vehicle comprises a pressure hull, a vehicle bow and a vehicle stern, wherein the vehicle bow and the vehicle stern are arranged at two ends of the pressure hull, a liquid control system which is used for controlling the liquid flow is arranged in the pressure hull. The manless underwater vehicle is characterized in that adjustment cabins are respectively arranged between the vehicle bow and the pressure hull and between the vehicle stern and the pressure hull, a piston which divides each adjustment cabin into a liquid storage cabin and a water discharging cavity is arranged in each adjustment cabin, the piston is controlled by the liquid control system and does reciprocating movement in the adjustment cabin, and a permeable hole which is communicated with outside part is formed in the water discharging cavity. The manless underwater vehicle is simple in structure, convenient to arrange, huge in adjustment ability and capable of adjusting trim gestures.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to an unmanned underwater vehicle with improved buoyancy and pitch adjustment capabilities. Background technique [0002] Underwater vehicles are widely used in marine scientific research, marine engineering, marine resource exploration, military reconnaissance and other fields. Underwater vehicles need to use special buoyancy adjustment devices to maintain their stable floating state during operation. There are many kinds of buoyancy adjustment devices currently in use, such as the use of high-pressure gas cylinders + ballast water tanks. In this way, the device needs to operate continuously and consumes a lot of energy; for example, the oil bag method is used, the device has a simple structure, but its adjustment ability is limited, and the pitch attitude cannot be adjusted. Contents of the invention [0003] The technical problem to be solved by the pr...
