Work. In tow deliver hydroelectric power plant on the place of work. The longitudinal axis of the main chute 20 should be parallel to the pointer 45 direction of flow of water 19. Fixed on the bottom with anchors pontoons 46 and 47. The flow of water passing through the grid 59 is adjusted sub-genres water guiding shields 38 and 39 and sent to the Central intake shield 36, the ends of which at the end of 60 rises above the surface 18 water 19. Thence with an increased rate of flow enters through the window 61 in the main chute 20, and through the Windows 62 and 63 in the auxiliary 34 and 35 of the gutter.

Synchronously the tabs 48 and 49 are in contact with the studs 5, available on the slave drum also rotates on its axis and is designed to adjust the tension of the endless chain 9.

In the process of moving the endless chain 9 on the surface 18 water 19 always remains a gap of 17, as hydroelastic 15 has a window 16, and the distance from the frame 22 to the bottom 53 of the main chute 20 during operation of the power unit 21 continuously. Because of this, the flow rates between water 19 and the endless chain 9 is missing.

On the section of track between the leading drum 3 and a driven drum moving the chain 9 is in contact with the supporting rollers 54 and podderzhkoy rollers 55 which rotate on sealed bearings, reducing the resistance movement 7 main and auxiliary 8 units.

When the movement of hydroelastic 15 from the slave drum pulley 3 plane 58 of hydroelastic 15 occupy a parallel position relative to the planes of the 10 main links 7 and planes 57 supporting links 8, which reduces the pneumatic resistance when exposed to air.

When approaching the racks 11 to the surface 18 water 19 hydroelastic on 15 Sha is nirah 13 is rotated and due to gravity takes its operating position, contacting elastically-resilient lugs 56. Perceiving the force from the flow of water 19 drives the endless chain 9.

Due to the fact that the basic parts 7 and auxiliary links 8-shaped frame made from a material - metal rod type, and the host 3 and slave 4 drums on the perimeter, which has the shape of a polyhedron, also made from a material rod type, dripping water 19 to freely return to the main chute 20.

To stop the operation of the power unit 21 includes a coupling 65. The pump 66 pushes the water 19 in the back hydroelastic 30, from which through the conduit 31, the water fills hydroelastic 27. When the mass of the water 19 in hydroelastic 27 will be equal to the weight of the power unit 21, the latter rises in the vertical plane along the slots in the uprights 24, discontinuing rotation of the master and slave drums, and hence the operation of the pump 66.

With the aim of lifting the power unit 21 to the desired height open the valve 33. Water 19 from the reserve tank 30 by gravity discharged into hydroelastic 27, increasing additional weight of the latter. The power unit 21 rises to the desired height with respect to the plane 18 water 19 which flows through the main chute 20. The valve 33 is closed.

Start hydroelectric power is produced by opening the valve 29.

SUBSTANCE: water flow energy converter into electrical energy consists of a body with open flow windows being provided in the lower part of the body during low-tide and in the upper part during high-tide. The converter also includes endless band inside the body, which is reeled on drums, operating blades in the form of double-lever plates. 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. The movable gate takes horizontal position to allow free flowing during low-tide.

EFFECT: improved effectiveness of device, simple structure and operation, wade range of application.
