FIELD: construction.

SUBSTANCE: invention relates to alternative sources of power, in particular, to tidal power plants. The method consists in the fact that a part of basin water area closed by a dam at the side of the sea, with a river flowing into it, exit of which into the sea is via hinged or pontoon gates only during ebb, together with the river bed from its mouth and to the dam is cut with the dam designed to create upper reach at the side of the river bed. The difference is discharged into lower reach via water conduits adjusted in the dam, to which submerged power units are connected. On the way of the river bed displaced by the dam to one of basin coasts, they install hinged or pontoon gates providing for only single-sided passage of a tidal wave into the water area of upper reach, providing for level difference necessary for turbines operation regardless of change in tide phases.

EFFECT: increased efficiency of power plant operation with lower costs and less time.

SUBSTANCE: main and auxiliary vertical double blades are arranged on a turning cantilever. The axis of the main blade in a central part is connected to a casing on the cantilever end with a return spring, and its planes are fixed asymmetrically on the axis, i.e. with a larger surface area towards the cantilever attachment centre. The auxiliary blade has symmetrical planes and is kinematically connected to the main one through transmission ratio providing a larger turning angle to it. A multiplier is of combined type, and it has additional inner conversion relative to slow back-and-forth movement of the cantilever axis to increased one-way rotation of a multiple-pole generator. In case of an underwater design, axes of blades and cantilevers are equipped with waterproof sliding bearings excluding the need for additional sealing of inner volumes of the blade part of the cantilever and the load-carrying housing.

EFFECT: invention contributes to creation of surface and above-water, noiseless and safe wind driven units, as well as bottom hydraulic units in river, running and sea streams providing simple and compact designs with possibility of their being lifted to the surface for periodic inspection or repair.
