RENEWABLE POWER SONAR DETECTION DEVICE Russian patent published in 2022 - IPC B63B22/00 F03B13/22 

FIELD: marine technology.

SUBSTANCE: invention relates to the field of marine technology, in particular to marine autonomous devices for detecting surface and underwater targets, and has the ability to replenish electricity during operation. A hydroacoustic detection device with a renewable power supply is proposed, which consists of a housing (7) in which an autonomous electric source (9) and an electric generator (8) are located, the housing (7) is made in the form of a sealed cylinder in the upper part, the system devices are located inside the housing hydroacoustic detection (4), the GLONASS global satellite navigation system (3), a communication and control system (6) with an antenna (2) in a sealed radio-transparent cap (1), an air exhaust valve with a pressure sensor (5), a screw propeller (12) is rigidly fixed to the rotor of the electric generator, installed in the side cutout (13) of the housing, hydrophones of the hydroacoustic detection system (10) are located below, in the lower part of the housing there is a hole to which a pipe (11) of a smaller diameter with a load (15 ) and notches (14) at the end.

EFFECT: use of the proposed hydroacoustic detection device will allow for a long time to monitor the water space in the coastal zone, in the straits and the economic zone of our country, to prevent unauthorized entry and passage in special zones (Northern Sea Route), and illegal economic activity.
