The invention relates to structures for converting the energy of the incoming flow of water into electrical energy.

Energy production, which is a necessary tool for the existence and development of mankind, has an impact on nature and human environment. On the one hand, in the life and productive activity of man so firmly joined heat and electricity that people even can not imagine their existence without it and consume for granted inexhaustible resources. On the other hand, people more and more attention focuses on the economic aspect of energy and requires clean-energy industries. This suggests the need to solve complex issues, including the reallocation of funds to cover the needs of humanity, the practical use in the national economy achievements, search and development of new alternative technologies for heat and power, etc.

Known hydropower plant at the request of the Russian Federation for invention №93029865 containing the two screws rotating in different directions, connected by shafts respectively with the rotor and stator of the generator. While the stator of the generator is rotated.

This is a big drawback, since the stator must be placed in a stationary CDF is truncated, designed for fastening to the support and output wires. In addition, the rotor, the stator and the screws rotate with the same angular velocity. If you design a high-speed generator having a rotational speed, for example, 3000...10000 rpm, to design a propeller with a diameter of more than 1 m will fail for reasons of strength due to the large centrifugal loads.

For example, when n=10000 Rev/min and D=1 m/s speed of rotation of the rotor at the periphery will be

i.e. almost 2 times the speed of sound in air is comparable to the speed of propagation of sound in water and invalid for strength conditions.

For industrial generators for maximum power, you must have the screws with a diameter of 5...10 m and more. In this case, the rotation speed of the screws should not exceed 50 rpm, i.e. you need to install the multiplier, increasing the frequency of rotation of the rotors 10...20 times. In addition, preferably the stator of the generator to perform non-rotating.

Known source of energy in U.S. Pat. US 6476513 B1, 05.11.2002 how, F03D 9/00, prototype, containing the generator and the hydraulic actuator, and the generator is made birotational and includes case and two rotors, and a hydrodynamic drive is made in the form of two coaxial spaced screws that are installed on the shafts and raspolozenija both ends of the generator.

Known hydrogenerator in U.S. Pat. FR 1137394 A, 28.05.1957, F03 13/10, prototype. This hydro generator includes a generator and a hydrodynamic drive, while the generator is made birotational in the form of a cylindrical body with an excitation winding of the inside and the outer and inner rotors and the hydrodynamic drive is designed as two coaxially located turbines, one of which is installed on the outer surface of the outer rotor, and the other on the inner rotor.

The disadvantages are the same.

The task of the invention to increase the efficiency with the reduction of its size and increase in power.

The technical result is achieved due to the fact that the hydrogenerator containing the generator and the hydraulic actuator, and the generator is made birotational, in the form of a cylindrical body with an excitation winding of the inside and the outer and inner rotors and the hydrodynamic drive is designed as two coaxially located turbines, one of which is installed on the outer surface of the outer rotor, and the second on the inner rotor according to the invention the generator is equipped with magnets mounted on the outer and inner rotors are located respectively outside and inside the housing, and the turbine is made of screw, the second of which set is on the inner surface of the inner rotor. The generator can be placed in the casing. The enclosure can be attached to the hinge, located in a vertical plane passing through the center of mass and allowing rotation in horizontal and vertical planes. The hinge can be made with limiter vertical rotation, preventing the screws from damaging the rack. The cavity of the generator hermetically sealed, filled with lubricating fluid and communicates with the pressure compensator.

The invention is illustrated in the drawings, where:

figure 1 shows the scheme of the hydrogenerator,

figure 2 shows a view As in figure 1,

figure 3 shows a view B figure 1.

The hydrogenerator (figure 1) contains the generator 1 is made integral with him hydrodynamic drive 2, running on the energy of water, and consists in turn of a cylindrical body 3, the outer rotor 4 and the inner rotor 5, are installed respectively inside and outside the cylindrical body 3 concentric with him. The generator 1 includes a field winding 6, is made within the cylindrical body 3, and the outer magnets 7 and the inner magnet 8 mounted respectively in the outer and inner rotors 4 and 5.

Hydrodynamic drive 2 (figure 1) consists of two screw turbines - 9 external and internal 10. Screw turbine - turbine working lop the TCI which is made in the form of a screw. External screw turbine 9 is set on the outer rotor 4 and the inner screw turbine 10, the inner rotor 5.

The rotors 4 and 5 are installed on the housing 3 on the bearings 11 and is sealed with a seal 12. The cavity b of the alternator 1 is filled with lubricating fluid.

The application of this scheme will reduce the diametrical dimensions of the generator 1 and the screws 3 and 4, to increase their efficiency, to reduce the diameter of the installation is almost 1.5 times and reduce the level of noise generated by a screw turbines 9 and 10.

To the housing 3 of the generator 1 (Fig 1 and 2) in its middle part radially attached to the supports 13, attached to the base 14 with the hinge 15 in the area of the center of gravity CG. The hinge 15 allows the rotation of the generator 1 in a horizontal plane and rotation by a small angle α in the vertical plane. The hinge 15 has limiters vertical turning 16. The use of limiters vertical turning 16 prevents adjust to any misalignment of alternative source of energy vertically.

External screw turbine 10 may be enclosed in a casing 17 (Fig 3).

During operation of the installation it is set in the area of permanent water flow. The water flow actuates the hydraulic actuator 2 (figure 1), i.e. screw turbine 9 and 10, which results in rotational movement of the rotors 4 and 5. While it is preferable that ro is ora 4 and 5 rotate in opposite directions, this will increase the rate of change of magnetic flux passing through the coil (winding) excitation 6 of the generator 1. The magnetic field crosses the field winding 6 and occurs EDS. Produced electrical energy is supplied by electrical wires to the energy consumers (figure 1...3 circuit output wires not shown).

The casing 17 prevents radial flow of water under the action of centrifugal forces and increases the efficiency of the installation.

The use of the invention will:

1. To ensure high efficiency through the use of two screw turbines, their rotation in opposite directions and use the shell.

2. To get more power through the use of the screw maximum diameter possible to ensure that there was maximum flow of water, the application of the maximum angular velocity of rotation of the screw turbines from the condition of strength, use a screw turbine, having a large active surface and allowing to obtain greater power generator without increasing its diametral size and weight.

3. To reduce the diametrical dimensions of the generator through the use of birotational schema.

4. To simplify the design of the device as a whole by combining basic units - generator and a hydrodynamic drive, and reduce the number of parts.

5. About the especial reducing noise, created by the screws through the application of the shell.
