The closest analogue (prototype) of the invention include hydroelectric station, located on the open water surface of the river with a free driving energy of the water stream containing hydraulic motor, consisting of a block blade screws axial type, installed to meet the water flow and is located inside the housing in a horizontal, parallel to each other position in the bearings with the possibility of transmitting rotation to the rotor of an electric generator driven by toothed belt, and the nozzle (see KR 20110107881 AND 05.10.2001, F03B 17/06).

The objective of the invention is the provision of opportunities for continuous operation of a hydroelectric power station, the expansion of opportunities for mass use in places inaccessible to connect to the public network (power consumer).

This problem is solved in a hydroelectric power station electricity generation, located on the open water surface of the river with a free driving energy of the water stream containing hydraulic motor, consisting of a block blade screws axial type, installed to meet the water flow and smeshannyh inside the housing in a horizontal, parallel between a position in bearings capable of transmitting rotation to the rotor of an electric generator driven by toothed belt, and a nozzle according to the invention the hydraulic motor consists of a blade screws axial type, located inside the housing, a blade screws transmit the rotation of the gears directly, one blade propeller on the other blade propeller, while the blade screws on the principle of work, are leading, but in the interaction between a spin in different directions, which summarizes the mechanical power blade screws are transmitted to the rotor of the generator, the nozzle is made to the mixing chamber and located outside the housing for ensure suction of the output stream from the housing, increasing the speed of rotation of the impeller screws, the front ends of the blade set screws in the bearings, and the rear is placed in the thrust bearings on the horizontal position, resting on tapered heel, providing concentrations blade screws relative to the housing, and the blade screws are made of right and left rotation, which generally ensures the efficiency of the hydraulic motor and electric generator on the open water surface of the river with a free driving energy of water flow.

On Phi is .1 depicted hydroelectric station afloat in the three-dimensional image. Figure 2 shows the scheme of movement of the working fluid and the flow of water through the block blade screws and the mixing chamber of the nozzle. Figure 3 shows blade propeller in the housing, a side view in section. Figure 4 shows the actuator blade screws toothed drive belt. Shows the drive timing generator drive belt. Figure 5 shows a drive rotary screw gears. Shows the drive timing generator drive belt. Figure 6 shows a block blade screws, interacting with the direction of their spins, front view. 7 shows a block blade screws left and right of the direction of rotation and the movement of the working fluid between the blade screws acting on the blades of the screws, in plan, in the context.

The hydroelectric station is located on the open water surface of the river with a free driving energy of water flow. Hydroelectric station consists of a float 1, located on the water surface and fixed to the support 2 bugreport 3. The float 1 is the generator 4, placed inside the structure 5. Under the float 1 at the depth of water flowing space of the river is a hydraulic motor consisting of a block blade screws 6 axial type, installed to meet the water flow in horizontal, parallel between the Wallpaper position. Blade screws 6 are placed inside the cylindrical casing 7. The front ends of a blade screw 6 mounted in bearings 8 on the supporting ring 13. Rear ends placed in the thrust bearings 9 slide the horizontal position, resting on tapered heel 10, providing concentrations blade screws 6 relative to the housing 7. On the outer perimeter of the housing 7 is located the nozzle 11 to the mixing chamber 12. In the operating mode blade screws 6 pass the rotation of the rotor of the electric generator 4 toothed drive belts 14 and 15.

Blade screws 6 pass the rotation of the gears 16 directly, one blade screw 6 on the other blade propeller 6. All blade screws 6, principle of operation, are leading, but in the interaction between a spin in different directions. Therefore, the blade screws are made of right and left rotation.

Hydroelectric station operates as follows.

Through the power blade screws 6 hydraulic motor flows through the water flow freely and continuously with hydraulic energy. When the mass movement of water through the internal space of the housing 7 is formed of the working body, moving in the direction of the axis of rotation of a blade screws 6. Blade screws 6 straightforward perceive the flow of working fluid from the hydraulic energy and convert the form it into a rotational movement of the blade screws 6 into mechanical energy.

Blade screws 6 pass the rotation of the gears 16, directly, right blade propeller 6 - right rotation transmits rotation to the left blade propeller 6 is a left rotation. All blade screws 6 are leading, but in the interaction between a spin in different directions. When the mass movement of the working medium in the interior space of the housing 7 of the working body is moved in the direction of the axis of rotation of a blade screws 6. Thus to overcome the hydraulic resistance and friction between the parts of the hydraulic motor is wasted energy, reducing the flow of the working fluid and the number of revolutions of the impeller screws 6. To increase income of the working fluid to blade screws 6 water flow is directed both outside the housing 7. Next, the water flow passes through the mixing chamber 12 of the nozzle 11 with greater speed and force of the stream than the working body extending from the housing 7. Due to the difference of the velocities of the flow creates a vacuum in the mixing chamber 12 of the nozzle 11, which creates a suction mode exit stream of the working fluid from the housing 7 water flow outside the housing 7, which increases the traction of the working fluid inside the housing 7, which increases the speed of rotation of the impeller screws 6 and the rotation of the rotor of the electric generator 4. Individual blade screws 6 in total in imagesetpixel block hydraulic motor summarizes mechanical power blade screws 6, transmitted to the rotor of the electric generator 4.

In General, a combination of technical solutions to ensure efficient operation of the hydraulic motor and electric generator 4 on the open water surface of the river with a free driving energy of water flow.
