The invention relates to hydropower and can be used to convert the kinetic energy of the flow of water into electricity on rivers, preferably flowing, and/or offshore (for converting kinetic energy of ocean currents, including tidal).

Known hydropower plant comprising transverse to the turbine shaft is mounted in bearings fixed to the frame, provided with a flow shaper, made with possibility of fixation to shore or bottom supports, and the generator, kinematically coupled with the turbine, the flow shaper is made with the possibility of shading the lower part of the rotor of the turbine (see SU # 1700276, CL F03B 7/10, 1989).

The disadvantage of this device is evident with a relatively small mass and size characteristics of the device, since the torque generated by the rotation of the turbine rotor, leads to the reversal of the hydraulic unit and/or rollover or deterioration of conditions of interaction of the rotor of the hydraulic unit with the incident flow, in addition, not enough high speed of water flow acting on the rotor of the hydraulic unit, which reduces the capacity of the generator.

The disadvantage of this device is its insufficiently reliable positioning in the horizontal plane, eliminating the possibility of its use offshore, when it is placed without landing on the bottom in the thickness of the waters.

The object of the invention is to provide a reliable positioning of the device in a horizontal plane,

The technical result obtained when solving the tasks, is expressed in the stabilization of the parameters of the spatial distribution of the installation relative to the incoming flow. In addition, this provides the possibility of using the device for a marine, when it is placed without landing on the bottom."

The problem is solved in that in the hydropower facility containing installed on the frame of the water turbine, made with the possibility of rotation around the horizontal axis, kinematically connected to an electric generator, a generator of a flow formed in Pharmacopoeia, communicated with the working channel, which houses the turbine, anchor, ballast tanks, in an amount sufficient to stabilize the spatial position of the installation for pitch and roll, and the steering wheel according to the invention is used an even number of turbines, placed symmetrically relative to the longitudinal axis of the apparatus along which is oriented to the axis of rotation, wherein the direction of rotation of the turbine opposite, with the lower plane of the flow generator is placed horizontally, with the ends of the rod anchor device attached to a rope connected to the anchor, fixed on a slide mounted for reciprocating movement on the uprights, rigidly mounted on the sides of the installation at its front end, in addition, the wheel is made of two plates attached to the frame on each side of the installation at its rear end, beyond the hydrodynamic shadow of the flow generator, wherein the total length of the cable and pull exceeds the depth of the waters at the location of installation. In addition, the drive reciprocating movement of the slide made in the form of power cylinders double acting. In addition, the control unit is made as a separate node, implemented with the ability to remotely change the buoyancy, and the reported cable-cable with control�sponding mechanisms controls the spatial position of the hydroelectric plant.

The set of essential features of the invention provides a solution to the technical problem is to ensure stability of the unit, while increasing the capacity of the generator.

In addition, with a relatively small cross-section of the working channel provides the possibility of significantly increasing the size of the blades interacting with the fluid flow, when performing shoulder blades in the form snakebytes spiral, to minimize the vertical dimensions of turbine.

Signs of "the bottom plane of the flow generator is placed horizontally" exclude the process of recovery part volume� thread up to the bottom edge of the shaper flow that would have occurred with the lowering of the reception of the edges of the flow generator below its level and, thereby, eliminates the loss of part of this energy flow, to overcome gravity.

Signs of"the total length of the cable and pull exceeds the depth of the waters on where the settings" allow you to change the height of the mounting position above the bottom, up to the surface, while maintaining the "binding" of the installation in area waters. It is not necessary to equip the plant means "coiling-uncoiling" of the webbing of rope.

Signs of the second paragraph of the claims specify the design, the drive reciprocating movement of the sliders.

The signs of the third claim of the invention simplifies the maintenance of the control unit.

The claimed device is illustrated by drawings, where Fig.1 shows a longitudinal section of the installation; Fig.2 shows its front view, Fig.3rd view from the top.

The drawings show a hydraulic turbine 1 mounted in the working channel 2, the electric power generators 3, the axis of rotation 4 of the turbine 1, the flow shaper 5 on the frame 6, the flexible rod 7, the wire 8, the armature 9, the Central ballast receptacle 10 mounted on the bottom frame 6, and is also mounted on the frame 6 on-Board ballast tanks 11 and end ballast tank 12, the movable plate 13, the rack 14 with braces 15, floaters, 16, power cylinders 17, the control unit 18, the cable-the cable 19. Also shown are the surface 20 of the water area 21, the longitudinal axis 22 of the installation, cable pin 23 of the electric power generators 3, water flow (current) 24.

As part of the installation used an even number of Ki - �of returnin 1, placed symmetrically relative to the longitudinal axis 22 of the installation, along which is oriented to the axis of rotation 4, wherein the direction of rotation of the turbine opposite. As the turbines used 1 unit of known construction, made with the possibility of horizontal rotation, preferably in the form of a shaft provided with snehapanam blades (like the Archimedes screw). Each turbine operates on one generator 2, which is a structure of known type, waterproof performance, with the operating parameters defined by the particular operating conditions, the generator 2 in a known manner kinematically coupled with the turbine 1 and, via a sealed cable pin 23, is associated with the power receiver (not shown) mounted either on the shore or on a platform, in a known manner mounted on pile base or marine mining platform. It is advisable to use a DC generator, voltage regulator, complete with generators to use inverters (called nodes not shown).

Driver worker thread 5 is formed as a converging funnel, a larger cross-section which is turned towards the stream, and less directed to the turbine 1, the lower flat�th the flow generator is placed horizontally.

Ballast tanks 10-12 made by one constructive plan, have remotely operated valves (not shown) providing communication from the cavity of the container with the external environment, and connected, via hoses, to withstand a pressure of 5-10 atmospheres, to the battery of compressed air (calculated at the appropriate pressure is not shown in the drawings). To recharge the battery may be spent of the electricity generated by the installation, on the dissociation of water or the generation of pressure by the creation of electrohydraulic effect. Ballast tanks differ by location (Central receptacle 10 mounted on the bottom frame 6, on-Board ballast tanks 11 - on the sides of the installation, and trailer 12 are installed at the end of the installation, the opposite driver workflow 5). In addition, the Central ballast receptacle 10 can be divided by transverse bulkheads at least two compartments along the length of the installation.

The free ends of flexible rods 7 fixed to the sliding blocks 16, which are mounted for reciprocating motion (up and down) on the rack 14 mounted on opposite "sides" of the device in the front.

The control unit 18 is made as a separate node, performed in a known manner, with the possibility of dis�Antonovo change the buoyancy (equipped with ballast tanks, provided with means making them in sea water and drainage, controlled by radio or acoustic channel) and notified to the cable by a cable 19 with the control mechanisms controls the spatial position of the hydropower plant (means of adopting them in sea water and drainage, as well as the operation of power cylinders 17). A sensor (not shown), giving the signal for testing the stability of the platform in a horizontal position, is the gyroscopic sensor of known construction, adapted to the operation conditions of the power plant.

The wheel comprises two steering plates 13 fixed to the frame 6 on the sides of the installation at its rear end, beyond the shade of the hydrodynamic flow shaper 5.

The claimed device is as follows.

In a known manner reveal the depth location of the most high-speed section of water area. Further to this spot on the surface 20 of the water area 21 is towed afloat (with empty ballast tanks 10-12) installation. Further, remotely open the ballast valves of these tanks, take them in water in an amount necessary for immersion mounting in water. After landing installation at the bottom of the post on the bottom of the anchor 9 (for example, the anchor device are sealed in a known manner in the bed of a water body 21 so that it n�fell before installing, if you look along the water flow (flow) 24). After that, the cable 8 connected with flexible rods 7 (fixed on the sliding blocks 16 mounted for reciprocating movement on the posts 14 mounted on opposite "sides" of the device in the front), fixed to the anchor 9 (the length of the rods 6 are selected so that the total length of rods was enough to ensure that when pdfsplit the device was in the area of the most high-speed section of the water water, wherein the total length of the cable and pull to exceed the depth of the waters on the location of the installation). These works and the dismantling of named nodes perform involving divers or remotely-operated underwater robot manipulators known design.

Then in ballast water tanks 10-12 serves the air, providing buoyancy install a slightly larger zero, and the air supply is controlled so that the device has surfaced on an even keel", i.e. its longitudinal axis 22 were in the horizontal plane. In the process of these operations, the turbine is stalled, such as a friction roller, preloaded to the turbine shaft (not shown). The separation of the ballast tank 10 into compartments allows you to "enhance" the work of the aft ballast tank 12 at a corresponding filling (drained�and).

After the withdrawal of the device in the working position (in the zone of maximum velocity of water flow) turbine start in work, freeing the shaft from contact with said friction roller.

Confusingly funnel the flow generator 5 provides an increase in speed of water flow, interacting with the turbine 1, in proportion to the relationship of the squares its input and output sections. Therefore, even at relatively low absolute values of the speed of water movement in the zone of maximum velocity of the water flow 24 to the impeller of the turbine speed the water pressure is large enough.

Steering plate 13 provide permanent retention of the longitudinal axis 22 of the device on the rod thread, "working" like a weather vane, a tracking direction of the water flow 24.

The rotation of the turbine wheel 1 rotates the generator, kinematically associated with it. The electricity generated by the cable pin 23 goes to the power receiver (not shown) mounted outside of the reservoir. The use of DC generators, voltage regulator, provides independence from changes of velocity of flow 24. The use of inverters included with the generator 2 converts DC to AC.

During the initial stage positioned�ing plants are used change the location of the slide 16 on the racks 14 (since the free ends of flexible rods 7 fixed to the slide 16), when the vertical displacement of the latter varies the arm of application of the load acting along the thrust, allowing minimization of the trim frame 6 of the device (in this case procrastination 15 eliminate the deformation of the uprights 14 under the action of the load transmitted to the flexible rods). Thin stabilizing the platform in a horizontal position provides automatic failover indications of the gyro sensor, the control unit generating commands to start the transfer pumps installed in ballast tanks, which eliminates the deviation in roll and pitch during external perturbations.

To move the installation to a new job blow ballast tanks 10-12, providing lift mounted on surface 20 of the water area 21, fastened to her towline afloat and move to a new place. Remove the anchor device and move it to the new plot.

Then it repeats.
