MODULAR AUTONOMOUS UNMANNED UNDERWATER DEVICE Russian patent published in 2023 - IPC B63G8/00 B63C11/48 

FIELD: underwater marine technology.

SUBSTANCE: when the charge level of power sources (6) drops below the required level, the computer (15) sends a signal to the control electronic unit (16), which generates a control radio signal to the propeller motor (19) and independent steering devices (20) and a modular autonomous uninhabited underwater vehicle rises to the desired depth. The computer (15) initiates the opening of the electric locks (31). Devices for converting wave energy into electrical energy (30) float to the surface and, affected by waves, generate electrical energy, which is used to charge power sources (6) via electric cables (33). After charging is completed, double-drum electric winches (26) are launched, pulling the devices for converting wave energy into electrical energy (30) to the metal case (1). The electric locks (31) are activated, fixing the devices for converting wave energy into electrical energy (30) on the metal case (1).

EFFECT: increased time of autonomous navigation due to the use of wave energy.
