SUBSTANCE: invention relates to small power engineering for transforming the flow of rivers and tides into angular kinetic energy on free-flow link hydroelectric power plants. The hydro-turbine consists of a hollow carrying shaft-cylinder with adjustable ballast, which makes it possible for the hydro-turbine to be fully submerged into water or bring it to the surface. On the shaft-cylinder are placed semi-cylinder arms, to whose ends are attached annular containers with ballast, which ensure neutral buoyancy of the hydro-turbine. On the shaft-cylinder are mounted equally along its length several discs or flat cylinders with grooves on the rims, to which are attached arms. Arms have the shape of the lateral sides of the hollow cylinder, cut-off longitudinally, thus, so that the discs are inscribed on the inner ends of the arms. A central hole is formed between the discs, of the surface carrying shaft-cylinder and the inner ends of the arms, through which communicate all vane spaces. As a result the flow goes through the entire turbine, touching the arms, which are located on the rear from the flow of the turbine end. The outer ends of the arms are tightened by rings-hoops and will form a multibladed cylinder, whose base is fully closed with the containers of ballast, tightly joined with the ends of the arms and hollow carrying shaft-cylinder.
EFFECT: hydro-turbine has a high coefficient of efficiency and is simple to produce.

The operating blades are bent relative to each other and provided with hinge in the point of bending. They are installed on the external side of endless band along the whole its length. The stabilisers are installed on drum shafts outside the body boards. The said stabilisers pull down endless band with blades with regard to the body bottom to activate part of the blades in the upper part of endless band during high-tide. Alternatively, the stabilisers lift the endless band to activate part of the blades in the lower part of the endless band during low-tide. There are vertical slots made in the body to adjust height of lifting or pulling down. The movable gate is attached to the body end side and directs flow to the upper part of endless band during high-tide.
