The invention relates to hydropower, and more particularly to a hydroelectric power plants, using the power of large and small lowland rivers, benthic marine currents, as well as open drains artificial origin, such as main and other channels.

The famous river hydroelectric power plant that uses the potential energy of water by the concentration of power in the form of the difference in levels, of which the most common PI in the form of hydraulic turbines, associated with power, and shipping gateway for the passage of vessels.

The disadvantages of dam storage hydropower plants are: flooding of vast territories occupied by arable land, forests and mineral deposits, transfer of an existing residential development out of the flood zone, the rotting of water in artificial reservoirs in the rapid reproduction of blue-green algae, the risk of disaster in the event of failure of dams.

These drawbacks are eliminated in hydroelectric plants, directly uses the kinetic energy of the fluid flow.

Known stream hydroelectric power plant, which is a chain blade conveyor belt around the sprocket axes are set perpendicularly to the surface of the earth, the stars in the grooves of the coastal part of the deepest parts of the river, and the blades working branch pipeline in the unfolded state can pass freely into the inlet channel, which is located in the river from the shore. Blade with a concave working surface with one end pivotally attached to the chain conveyor and are additionally connected by flexible links. To reduce the load on the bottom which I buoyancy of the latter. From the water inflow installed rotary valve with actuator (see patent USSR N 1821, CL F 03 B 13/12, 1926).

During the flow of water through the channel located at idle branch pipeline in the folded position the blades are fully deployed and due to the presence of flexible ties are held on the working branch perpendicular to the fluid flow, providing a moving chain conveyor and the rotation of sprockets, one of which is kinematically connected to a generator.

Uneven load on the bearings of the mass of the chain blade pipeline, the need to use special devices to reduce the load on the lower bearings of the sprocket causes the complexity of the design stream hydroelectric power.

The need for accommodation in the deepest place of the river undercuts on small rivers and canals.

The capacity of hydro power at given dimensions limited by the design of the blades.

These drawbacks are partially eliminated in the stream hydropower plants with horizontally placed paddle conveyor.

Known stream hydroelectric power plant that uses the energy of the fluid flow, periodically the th in the water body and a fixed body work in the form of a horizontally arranged endless rotary conveyor, frame drums and kinematically associated with the generator. The blade is a plate with a flat work surface and rigid links, forming in cross section a rectangular triangles with hinges at the vertices, with which they are connected with the conveyor. The casing is provided with a coaxially arranged with hand drums nozzles installed them in the opposite branches of the conveyor butterfly dampers.

The flow of water moving from one direction gets into the nozzle, closing the valve and is routed on the public portion of the conveyor, rotating drums. After this, the second valve opens, allowing free passage of water. At change of a direction of flow opposite to the above-described process is repeated in reverse order.

The need for full immersion of the hull streaming hydropower plants in water precludes its use on small rivers and canals.

The capacity of hydro power at given dimensions limited by the design of the blades.

The present invention is to increase the power stream hydroelectric power plants and the expansion of the scope.

The result is achieved by the hidcote case and installed a working body in the form of a chain blade conveyor, around the sprocket and kinematically associated with the generator, the blades are made in the form of rotatable around the axis of the damper.

The implementation of the blades in the form of rotatable around the axes of the valves allows ceteris paribus increase the working surface of the blade and thus to increase the capacity of hydroelectric power.

Partial immersion of the body into the water below the top of the blades on the working branch conveyor delivers the calculated traction and makes it possible to use streaming hydroelectric power plants on small rivers and canals.

The implementation of the blades overlap each other in the horizontal plane can reduce the resistance to movement of the idle branch line.

In Fig. 1 shows a General view streaming hydroelectric power plant in section; Fig. 2 plan of Fig.4; Fig. 3 section a-a in Fig. 2.

Streaming hydroelectric power plant includes a housing 1 with an inlet 2, confuser 3 and the diffuser 4, sprockets 5, 6, the shafts 7, 8, circuit 9, the blade 10 with the axes 11, a flexible connection 12, the valve 13 of the rotary actuator 14 and the generator 15.

Case 1 represents the welded hollow design, the ends of which in the lower part are coaxially arranged two hole the working body in the form of a chain blade pipeline.

To the inlet of the housing 1 is attached to the pipe 2, which is used for water supply and fitting 13 of the rotary actuator 14.

The branch pipe 2 inlet fluid secures the confuser 3, which is designed to expedite the flow of water passing through the housing, and the output of the cone to align the velocity of the internal flow and external flow. In the case of a partial immersion of the housing 1 into the water confuser and diffuser are made by narrowing and expansion of the internal flow only in the horizontal plane.

Chain blade conveyor consists of two chain drives containing sprockets 5, 6, circuit 9 and the shafts 7,8 connected with each other axes 11 evenly spaced along the length of the blades 10, made in the form of asymmetric rotary valves and serves to convert the kinetic energy of the flow of water passing through the lower part of the housing 1, a rotary motion of the shaft 7, kinematically associated with the generator 15.

The blades 10 are plates arbitrary, for example rectangular form with arbitrary, for example concave working surface, fixedly mounted on the axis 11, on which they are divided into onoline water flow and convert it into traction chains 9.

The presence of the blades extra short pieces allows you to increase the working surface, which, in turn, makes it possible to increase the power from the energy of the flow and increase the capacity of streaming hydroelectric power.

In addition, the implementation of the blades 10 in the form of asymmetric flaps with a longer and heavier main part allows the blades on the working branch conveyor when the stop streaming hydroelectric automatically be installed and be in a vertical position, which is necessary for the subsequent start.

The same effect can be achieved with the implementation of the blades in the form of a symmetrical flaps, one of the parts which perform the function main will be weighted.

Working surfaces of the main part of the blades 10 is connected with the axis 11 of the adjacent blades flexible connections 12, which are designed to hold the blade on the working branch conveyor in a perpendicular position relative to the incoming fluid stream.

The distance between the blades (step) is less than the length of their main parts, allowing you to get to idle branch pipeline overlap of the blades 10 to each other with the formation of the surface-type "fish dive housing 1 into the water.

The flap 13 of the rotary actuator 14 is a fixedly mounted on the axis of a flat plate shape which matches the shape of the internal cross-section of the pipe 2, but slightly smaller than the last and is used to start, stop, and power control and streaming hydroelectric changing the rate of flow of fluid.

The system works as follows.

In the initial position completely immersed under the liquid level of the housing 1 is filled with water, valve turning 13 is closed, the blades 10 on the working branch conveyor are in a vertical position, and a flexible connection 12 stretched to its full length, but not tight, the blades at idle branch conveyor superimposed on each other, forming a surface-type "rabie scales, and their flexible connection is fully drawn, the blade 10 with its flexible connections 12 to the sprocket 5, 6 are in an intermediate position.

After opening the valve 13 turning the flow of water through the confuser 3 and the pipe 2 at a rate greater than the rate of flow from the outside enters the lower part of the housing 1, which is the working branch pipeline and fluid begins to push up on the blade 10, in an effort to turn them around axis 11.

The blades 10, moving with the working branch line of the sprocket 5, out of the zone flow and enters an area of calm water, located in the upper part of the body.

Under the influence of the resulting force of gravity, representing the difference between gravity main long and extra short parts of the blade, turning around axis 11 begin to overlap each other to education at idle branch pipeline is well streamlined surface type "fish scales" with full sagging of flexible connections 12.

On the sprocket 6 is the reverse process of transition of the blades from the zone of quiet water flow, accompanied automatic full-turn of the blades 10 in the working position under the action of the same resultant force of gravity and hold them in this position by means of its fully stretched length, but not tense flexible connections 12.

Further lapasta stream hydroelectric, containing fully or partially submerged below the level of the liquid body and a fixed body work in the form of a chain blade conveyor belt around the sprocket and kinematically associated with the generator blades made in the form of rotatable around the axes of the valves allows to increase the capacity of hydroelectric power.

Partial immersion of the body below the level of the liquid makes it possible to extend the scope of application streaming hydroelectric power.

The implementation of the blades overlap each other in the horizontal plane can reduce the resistance to movement of the idle branch line.

In the case of the application of the invention to ask the Law to assign the invention of the author's name.
