The invention relates to hydropower, in particular gidroenergostroy that uses the energy of water flow to generate electricity.

Currently, to generate electricity are widely used hydropower plant (hydroelectric power), hydraulic architecture which creates the pressure of the water flow. The construction of hydraulic structures is very expensive and complex undertaking, which can only be done taking into account terrain, povnovodnosti river, navigable conditions on the river and other technical and environmental factors.

To supply electricity in rural and remote locations in the presence of rivers are very promising and inexpensive is to use the energy of the river flow to generate electricity, which envisages the construction of hydraulic structures.

So, widely known hydropower plant containing means providing pressure water stream and a turbine on the same shaft to which is mounted a rotor of the generator (ergetically installation as a means for providing pressure water stream used dam, providing a water level increase due to the accumulation of large volumes of water behind the dam and create the necessary pressure. The construction of the dam is very expensive and leads to flooding adjacent to the river areas to improve water and create the necessary pressure, causing waterlogging of land and environmental degradation. In addition, this hydropower plant is stationary, which complicates its use by consumers residing from it away due to the high cost of construction of transmission lines and energy loss during transmission.

Also known hydroelectric (ed. St. USSR N1462020, M CL F 03 13/12, 1989). This plant can be adopted as a prototype to the claimed invention.

A disadvantage of the known device, when power generation is its low efficiency associated with the fact that the stator 5 of the electric generator is connected to the shaft 10 and the speed of its rotation is determined by the speed of rotation of the containers 1, depending on the speed of water flow. In the proposed invention the speed of rotation of the rotor 20, connected to the axle 16 with liquid turbine 17, Opredelenie along.with. 1462020. The second reason for the low efficiency of the known device in comparison with the stated is that the turbine 6 is both gas and liquid streams, as well as the gas and liquid have different compressibility, the turbine cannot effectively implement the differential pressure (pressure) of the gas and the liquid. In the claimed invention air and liquid pressures operate on different turbines, thereby increasing the efficiency of electricity generation. Another disadvantage of the known device is its much larger dimensions in comparison with the invention of the performance is the same (the head), as the vessel is placed along the inside radius of hollow blades, the amounts are reduced from input to output from the execution of sealed cavities placed on the hollow shaft. In the claimed the same invention consistently reported capacity represent the channel formed by the turns of the spiral, where there is no irrational use of the internal volume of the tanks. This allows you to use the internal cavity of the shaft to accommodate the generator.

The technical result of the invention is to provide hydropower installation tool created and created offline mobile, environmentally friendly source of electricity.

The technical result is achieved by the fact that in hydropower installation comprising means providing pressure water stream and a turbine on the same shaft to which is mounted a rotor of an electric generator, hermetically separated from each other, according to the invention, the means for creating the pressure of the water flow is a pump large displacement with simultaneous pumping of water and air, having a working body, made in the form of a horizontal cylindrical spiral with hermetically United with her end walls, between the coils of which is formed a channel for the passage of water and air, and inside the cylindrical helix is installed pipe, which coaxially on the same shaft is placed a liquid turbine and the rotor of the generator, the stator of which is fixed on the other shaft and provided with a gas turbine, and in the upper part of the pipe section, which houses the generator, and in the lower part of the pipe section, in which is placed a liquid turbine, window, while the rotor and stator of the generator and the pipe is mounted for rotation relative to the body and each other, and to the ment last spiral blades are.

In addition, over the Windows installed cap.

The proposed hydropower plant in which to create a head of water flow used pump large displacement with simultaneous pumping of water and air, is an environmentally friendly, offline and mobile source of electricity.

In Fig. 1 shows a General view of gidroenergostroy; Fig.2 a longitudinal section of the installation of Fig.3 section a And the installation of Fig.2.

Hydropower plant contains the working body 1 mounted rotatably around a horizontal axis, made in the form of folded spiral flat sheet material 2, the coils which are placed with a gap between them, forming a spiral channel. The ends of the coils of the body 1 is tightly attached to the wall 3. The working body 1 contains the input window 4 formed on its periphery the last, penultimate turns and side walls 3. To the outer surface of the working body 1 along its cylindrical surface rigidly attached blades 5, forming an impeller. Inside of the working body 1 is placed pipe 6 mounted on bearings 7 for rotation relative to the body 1, to the walls 3 which allows a given depth of immersion of the working body 1 into the river. The pipe 6 is divided by a partition 12, hermetically attached thereto and containing a bearing unit 13, a liquid (left) and gas (right) cavity, and the outlet port 8 on the pylons 14 has a second bearing unit 15. Nodes 13 and 15 has a shaft 16 mounted on one end of the turbine 17. In the pipe 6 liquid cavity in the lower part is a window 18, telling her with liquid cavity of the working body 1, on which is placed a cover 19. At the other end of the shaft 16 fixed to the rotor 20 of the electric generator, the stator 21 which is placed on another shaft 22, mounted in a bearing unit 23, is placed in the pylons 24 of the outlet pipe 9, and a bearing unit 25 mounted on the shaft 16. The stator 21 is fixed impeller of the second turbine 26. In the pipe in the gas cavity in the upper part of the completed box 27, telling her with a gas cavity of the working body 1, on which is placed the cover 28 to prevent the ingress of liquid. To the lower part of the tube 6 attached the floats 29, providing a constant position of the pipe 6, is shown in Fig.2, or its wobbling about this situation at the power plant (nodes removal of power from the generator and the seal assemblies movable joints on che the current river water rotates an impeller with a working body 1 relative to the tube 6. The working body 1 rotates takes for one revolution of the window 4 a portion of the liquid and gas. For the second turnover of the working body 1, the liquid and the gas is fed from the first coil to the second and so on until you have filled all of the turns of the spiral channel. Because the volumes of coils from the periphery to the axis of the working body 1 is reduced, the liquid (in the absence of resistance at the output of the installation) will be free to flow from the previous turns in the next as long as the water will be at the same level in each turn (as in communicating vessels). For one complete revolution of the working body 1, each point of the spiral is consistently average, upper and middle lower positions. The result is that for each turn in the coil is fed a portion of the gas and water. The rotation of the working body 1 causes the water in the lower part of the orbits under the action of gravity to move to the center of the spiral, moving simultaneously and the portion of gas found between the portions of water. The pumped portion of gas, when the resistance at the outlet of the installation, is compressed as it moves along the spiral channel from input to output, and the water in the coils is increasingly deviates from the equilibrium position. In the coils located closer to the axis, the level has reached aetsa samoperesecheniem (return) in the previous turn of the spiral canal of the working body, that creates a marginal position in water levels. This state of water levels in the coils is optimal because it maximizes the increase of pressure in the circuit due to the difference of the heights of the columns of water in the coils. Owing to this self-tuning to ensure the optimum flow of water and gas in the working pressure range, with maximum efficiency, i.e. in the inner cavity of the working body creates maximum pressure of water and gas.

Due to stratification of the water and gas water is located in the lower part of the inner cavity of the working body and the gas at the top. During the rotation of the working body 1 tube 6 only sways in bearing assemblies 7 with regard to him, through the pipe 6 into the lower part of the cargo floats 29 in the position shown in Fig.2, with the window 27 is located in the upper position and informs the process gas of the internal cavity of the body 1 with a gas cavity 6, and the window 18 is located in the lower position, letting the liquid internal cavity of the body 1 with liquid cavity 6. Cover 28 protects from contact with the window 27 of the water during operation of the installation. The liquid stream is supplied to the turbine 17, giving it the 26, forcing to rotate the associated stator 21 mounted on the second shaft 22. With brushes of the generator is removed and electricity supply to consumers, and waste water and gas, respectively, back into the flow of the river and into the atmosphere. Thus the energy flow of the river is converted to the working body 1 in the pressure of the working fluid (liquid and gas), and then into electricity. To reduce the likelihood of liquid into the cavity of the generator is placed in the gas cavity of the pipe 6. In the case of leakage of liquid and gas through the seal on the shaft 16 in the partition perform the cavity, which is reported to atmospheric (conventionally not shown), which excludes mutual penetration of bodies working in the opposite cavity of the pipe 6. This eliminates the possibility of water ingress inside the generator, increasing its reliability. The cover 19 also serves to prevent the ingress of gas inside a liquid cavity of the pipe 6 in case of its breakthrough of the liquid cavity of the working body 1. Mutual protivobloshinye rotor and stator of the generator provides maximum power generation.

Thus due to more complete use of energy excess pressure of each working body (W is her hard-to-reach places not habitable areas or in places with a high cost of electricity.

In General, the proposed hydropower plant is easy to manufacture, cheap and provides the ability to generate electricity on any river without building a complex of hydraulic structures.
