The inside of the case is inserted with a small clearance of the turbine wheel, which is a hub 19 which by means of spokes 20 are connected with the sleeve 21, which is at an angle α equal to 70°, to the line diameter is welded to the blade 22. To both end sides of the sleeve and hub bolts turned down very low side wheels 23 with a Central hole for passage of the shaft 24. In the second section hosted a three-phase generator of electric current, comprising a housing 25, closed the lid 26, into which is inserted the rotor 27, mounted on bearings 28. Ha rotor pressed two steel tip 29 having six teeth. Tip one who alouini rotor has a magnetic North pole N, and the tip of the other half of the South S.

A mobile flow hydroelectric power plant as follows.

After selecting the installation site, where there is a rapid course and a great mass movement of water with sufficient depth hydroelectric through the tow is delivered to the installation site, drop anchor 2 and divers put them on the bottom of the river. After checking all systems opens the shut-off valve 47. A large mass of water enters into the body conduit of larger cross-section 5 with velocity V and forth through the housing conduit of smaller cross-section 6 has more speed out of it. While water under static and dynamic pressure rises in the pressure tube 46 up to a height ofh=V22gwhere V is the speed of the water flow, and g the acceleration of gravity (Roman Kurcewicz. The five elements of Aristotle. Our ksiegarnia. Warsaw, 1977, p.52). Then the water enters the inlet 16 of the turbine of the hydraulic actuator 13, a spherical chamber 15, and from there to the turbine buckets formed by the sleeve 21, the blades 22 and the side disks 23. Spherical camera 15 allows water to flow to act simultaneously on several blades 22, which increases the power on the turbine shaft (figure 8 arrows). After passing through the turbine, the water flows into the outlet chamber 17 from which the pipe 48 is removed into the body conduit of smaller cross-section 6, while in the discharge chamber vacuum is created, as in the sprinklers or ejector pump, which also increases the power turbine. The speed of movement of water in the body conduit of smaller cross-section 6 is 10 times more than in the case of a conduit of larger cross-section. When the shaft 24 of the turbine of the hydraulic drive with him is rotated and the disc 40 mounted on it, through which the rod 41 and the ball 42 rotates the disk 40 mounted on the rotor 27 of the three-phase generator of electric current. North and South poles of the electromagnets, the rotor 27 sequentially traverse the coils of the stator coils and their fields create a three-phase AC voltage that is supplied to three-phase step-up transformer 38 and followed consumers 39. Part of the electricity comes on C is the row of batteries 49. In the process, the amount of water supplied to the discharge pipe 46 can be adjusted shutoff valve 47, reducing or increasing the flow area and thereby changing the rotational speed of the shaft 24 of the turbine or stopping.

The technical result of the invention consists in higher efficiency, improved air-tightness and therefore increasing service life, increasing the number of generated electric current, it is not contrary to the ecology of the river.

SUBSTANCE: in a power-generating device a hydraulic turbine and a synchronous power generator (3) make an assembly moving jointly with a rotor (7) of the generator. The generator rotor (7) comprises poles with permanent magnets (1). The hydraulic turbine is arranged of propeller type or Kaplan type. Hydraulic turbine blades (11) are either fixed as capable of adjustment in process of installation or are arranged as controllable by means of mechanisms of hydraulic or electric systems. The central shaft of the device is installed with the possibility to adjust its position in longitudinal and radial directions relative to the specified assembly. The generator rotor (7) is sealed and fully submerged into water, allowing for presence of water in a gap (10) between the rotor and stator of the power generator. The device additionally comprises external electronic, electromechanical or hydraulic equipment for control of electric voltage and frequency.

EFFECT: invention makes it possible to simplify maintenance of a device and reduce its frequency.

SUBSTANCE: method is designed for generating electric energy using natural energy enclosed in high pressure formation. Proposed method includes placing of turbine in well to which high-pressure agent is delivered, and electric generator with cable. Turbine is installed in encased well between showing high-pressure formation and intake low-pressure formation. Turbine is connected by pipes with electric energy generator. Flow of agent from high-pressure formation into low-pressure formation and to surface is provided. Regulation of agent flow into annulus and tube space is provided by distributing valve arranged in lower part of assembly of turbogenerator and hole between housing of turbine and pipe connecting tube space with annulus.

EFFECT: provision of effective generation of electric energy using energy contained in high-pressure formations.
