Water electrified screen comprises source of electric energy, pulse converter, joined by means of cable to extended linear part, arranged in water medium. Pulse converter of electric energy is arranged as three-phased, and extended linear part consists of three isolated phased conductors, fixed on dielectric rope, each phased conductor comprises equal number of loop taps arranged at identical distance from each other, besides loop taps of phases in their arrangement strictly alternate along the whole length of extended linear part, to each loop tap, in point of folding, conductors of float electrodes are connected, moreover, connection point is insulated, and float electrode is made of light moisture-impermeable material in the form of ball with central hole. On ball surface there is a metal current-conducting mesh-electrode, which is connected via insulated conductor to tap of phased conductor. Phased float electrodes along linear part alternate in their arrangement by depth of submersion - one in near-bottom zone, and other - near surface of water medium due to length of conductor that connects float electrode and phased loop tap. |

Method for water-based object protection from unauthorised penetration Invention concerns technical means of active non-lethal counteraction to penetration to guarded objects based in water basins. The method of water-based object protection involves effect of different electric potentials on a trespasser appearing between electric current lines of different density, created in a water space, resulting in electric flow through the body of trespasser, impeding further movement. |

Method of electrification of trawls and device for realization of this method Proposed method consists in securing the electric power source in towing line in vicinity of trawl wing for supplying the electric current to system of electrodes located on trawl net envelope. Two independent power sources are secured at trawl wings on standard points of location of depressors. Wires supplying pulse current are connected to electrical connectors on control units of power sources; electrical fields formed by them are used for control of fish behavior in the course of fishing. Device proposed for realization of this method includes electric current generator driven by impeller actuated by energy of water incoming flow. It is placed in metal watertight housing and is provided with three-phase induction AC generator, bipolar current pulse oscillator, voltage, frequency and pulse duration control unit. Control unit is provided with single-contact connectors for connecting the wires running from electrodes on net section of trawl. |
