ACOUSTIC DEVICE Russian patent published in 2018 - IPC B63G1/00 H04K3/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the active interference devices, which can be used by the monitored object as the give object monitoring hydro acoustic means suppression device. Acoustic device contains the hermetically connected to each other bow and stern compartments. Bow compartment includes housing, fairing and bulkheads, electromechanical unit, connected to the fairing the bow compartment depressurization and the fairing jettisoning device, sources of acoustic noises, and pressure sensor. Stern compartment consists of the hermetically docked to each other and fastened with the help of wedge locks and shrouding band instrument and buoy compartments. Instrument compartment composition includes hermetically connected to the bulkhead housing, automation unit having the set of storage batteries and system of information processing and commands issuing devices, triggering device, pressure sensor and flooding valve. Separation system includes hermetically installed in the bulkhead opening piston with spring, on the bulkhead outer side the coil with halyard and locking device are located, which includes housing with the rod and electric igniter. Buoy compartment structure includes sealed housing, inside of which cover is hermetically installed, having fixed to the outer side reel with the shock absorbing cord. On the housing bottom data entry socket with the harness is installed having the pyroelectric igniter.

EFFECT: enabling possibility to interrupt the observer’s hydro acoustic means contact with the monitored object at the given depth in water.
