WATER AREA ACTIVE PROTECTION DEVICE BY THE SHOCK-WAVE IMPACT ON THE UNDERWATER OBJECT Russian patent published in 2019 - IPC F41H13/00 

FIELD: active protection devices.

SUBSTANCE: invention relates to the located in inland waters and on the continental shelf industrial and other protected objects water areas and infrastructure protection against underwater saboteurs and other underwater objects. Proposed is the water area active protection device by the shock-wave effect on the underwater object, including the electrotechnical unit, the body unit, the beam aiming unit with the hydro acoustic system with transmitting and receiving elements, power supply unit, control unit, pulse capacitor accumulator, switch, pulse electrodynamic radiator with loading coils and radiating external surfaces by the disk and coaxially covering the disk washer, which internal surface is opposite to the loading coils laying surface, wherein the pulse body unit is made in the form of two coaxial cylinders, between which a pulse electrodynamic radiator is located, in each of the coaxial cylinders the accumulator capacitors with switches are located, each of which is connected to the load coils of the disk and washer, respectively, at that, the beam aiming unit has eccentrically placed from the disk and the washer rear part hydraulic cylinders, wherein the transmitting and receiving elements are attached to the coaxial cylinders.

EFFECT: use of the invention will allow to increase the shock-wave effects efficiency on both biological objects (underwater saboteurs) and explosive underwater objects with hydro acoustic sensors.
