Description

The invention relates to the field of slaughter or stunning of living organisms and can be used in physical protection systems of objects.

Known electro-hydraulic effect (shock) [1], which consists in the occurrence of high pressure as a result of high-voltage electric discharge between the electrodes immersed in the liquid.

A means of active protection of water areas [2] is known, comprising a source of electrical energy, a cable line, a connecting device, a pulse forming unit including a charger, an energy storage device, a switch and a linear part made in the form of a system of electrodes between which a pulse discharge is generated, forming electrohydraulic shock to water.

The disadvantage of this means of active protection of water areas is the dependence of the electro-hydraulic shock parameters on the electrical characteristics of water. The characteristics of water, in turn, are influenced by its salt composition, the content of impurities and particles of various origins. In some cases, this can even lead to a “swelling” of the current from the electrodes instead of an electric discharge and, therefore, not to the occurrence of an electro-hydraulic effect.

The technical result of the invention is the provision of various degrees of physiological effects of an underwater explosion on a biological object and for active impact on the technical means of violation, regardless of the characteristics of the aquatic environment in the water area.

The technical result is achieved in that the formation of shock is carried out in an isolated volume filled with a liquid having known characteristics and mechanical transmission of shock to an external aqueous medium. The linear part of the electro-hydraulic impact device on the intruder in water, made in the form of a system of electrodes between which a pulse discharge is created, is placed in a sealed enclosure filled with a working fluid having the required characteristics. In an electric explosion occurring in a working fluid inside an airtight shell, a shock wave is transmitted through the walls of the shell to the surrounding aqueous medium. The hermetic casing can be made of non-destructible materials during explosion (for example, rubber), as well as of those that can be destroyed (for example, plastic, steel). This provides both single and multiple formation of electro-hydraulic shock.

The drawing shows a structural diagram of a device for electro-hydraulic impact on the intruder in water.

The device of electro-hydraulic impact on the intruder in the water contains a source of electrical energy (1), a cable line (2), a connecting device (3), a linear part (4), an airtight shell (9) filled with a working fluid (10), and a forming unit pulses (5), including charger (6), energy storage (7), switch (8).

The device electro-hydraulic impact on the intruder in the water works as follows. Electricity from the source of electric energy (1) is supplied to the charger (6), which provides the charge of the energy storage device (7). The switch (8) converts the energy stored in the energy storage device (7) into high-voltage pulses supplied through the cable line (2) and the connecting device (3) to the linear part (4) placed in a sealed enclosure (9) filled with a working fluid (10), and providing a spark electric discharge between the electrodes of the linear part, forming an electro-hydraulic shock acting on the intruder, a means of violation or sabotage (11).
