FIELD: power engineering.
SUBSTANCE: invention can be used to produce electric energy for domestic and industrial needs. Device for generating electric power from sea currents under ice 11 comprises stationary bed 9 with an electric energy generator 10, an attachment with column 1, inside of which there is shaft 2 connected to generator 10 by means of a reduction gear, and gearbox 8. Device contains an electronic system of parameters control installed on bed 9 and sections of vertical turbines 6 installed one above the other and rigidly fixed on shaft 2. Turbine blades are rigidly connected from above and below with strength circles. On outer side of turbines 6 there are three metal plates: deflecting 4, stabilizing 3 and balancing, attached above turbines 6 to column 1 by metal strips and attached horizontally to shaft 2 by means of a disk with a rolling bearing, to which rods are welded by one sides, attached by other sides to metal plates with the possibility of providing fixation of their position and exclusion of contact with turbines 6. Column 1 in places of fastening of metal strips is made with bulges. Horizontal fasteners are located between strength circles of adjacent sections of turbines 6. In the upper part of column 1 for attachment to the support of bed 9 a rim is made by means of welding, forming a flange with a central hole for passage of shaft 2, under which there is a spring resting on a rectangular plate, which contains four springs installed at its corners and resting on bed 9. Above the flange there is a disk with a central hole for passage of shaft 2, above which the support part of shaft 2 is installed. Thrust bearing is arranged between support part and disc. Barrel 2 comprises an upper part located above the support lower part and connected to it by means of a coupling disc with a ring resting on the downward movement limiting, made with possibility of coupling upward movement to stop torque transmission. Barrel 2 can be attached to the bottom by means of a cable passing inside it, one end of which contains an anchor, and the other end is wound on a cable coil located on bed 9. Column 1 in its upper part contains insulation 7, coming out to the surface before attachment of column 1 and going under water at 30% deeper than thickness of ice 11. Between heat insulation 7 and column 1 heating system is installed.
EFFECT: invention is aimed at increasing the energy capacity of the device.
