The invention relates to hydropower, in particular to the powertrain, which is driven by the flow of the current environment, and can be used to convert the energy of the current environment, such as the flow of rivers, into electricity.

Dam known hydraulic unit driven by river flow, comprising a floating base in the form of a catamaran, which is fixed to the active turbine, made in the form placed obliquely to the flow of the river of endless belt conveyor mounted on the ribbon blades and generator, kinematically associated with the endless belt conveyor, and each blade made in the form of a ladle able to fold and lie down on the conveyor belt during the transition from working on a single branch of the endless belt conveyor and having on the outer surface of pocket for automatically lifting blades, the flow conditions during the transition from idle to working position (RU # C1 2269672, 10.02.2006, F03B 9/00).

Known hydraulic unit does not take all the energy of the current environment, as his endless belt conveyor is at an angle to the flow and it has a single branch is not involved in the work.

The closest to the essential features of the claimed (prototype) of the dam is hydroelectric, driven by river flow is m, contains supporting frame with active turbine, made in the form of an endless conveyor placed across the stream and having two shaft covered by a flexible traction element with blades mounted with the possibility of rotation and fixation, and the support frame placed the generator, kinematically associated with one of the shafts, an endless conveyor, the rollers of the endless conveyor are located across the stream, and the workers of the branch of endless conveyor on which the fixed blades, are located one after the other (RU 2166664 C1, 10.05.2001, F03D 5/02).

The location of the shafts, an endless conveyor transversely of the flow of the current environment implies a loss of power unit as the transition region of the blades from one branch to another are not involved in the work that significantly reduces the total working surface of the blades. In addition, when the location of the branches of the endless conveyor one after another in the direction of flow also reduces the capacity of the power unit due to the lower energy of the flow after passing through the first branch.

The problem to which the present invention is directed, is to increase the total working surface of the blades and the impact on river flow, which will significantly increase the capacity of the power unit.

The problem is solved in that dam is a hydroelectric, driven by river flow, comprising a supporting frame with an active turbine, made in the form of an endless conveyor placed across the stream and having two shaft covered by a flexible traction element with blades mounted with the possibility of rotation and fixation in a predetermined position, and a support frame placed the generator, kinematically associated with one of the shafts, an endless conveyor according to the invention, the hydraulic unit is equipped with an additional flexible traction element, covering the shafts along the river flow, and transverse supports, connecting the flexible traction elements, the blades are mounted on axes fixed on the transverse supports, and between the branches of the endless conveyor has a divisor of the river flow.

The river flow divider is made in the form of a rectangular plate attached to the side edges to the shafts, an endless conveyor by means of bearing supports.

The maximum influence of river flow on all blades endless conveyor is achieved by the arrangement of his shaft along the river flow and installation of blades on the axes, mounted on the transverse supports, connecting the flexible traction elements of the endless conveyor, with the blades in areas of transition from one branch to another are also involved in the transformation as well, because of their angle of inclination with respect to the stream remains unchanged. In addition, the placement of branches at different levels in height allows you to extend the frontal impact of river flow on the unit and increase its capacity.

The presence of river flow divider eliminates the contact of counter-moving streams generated during the movement of the branches of the endless conveyor, which reduces the resistance to movement of the active blades of the turbine and also allows to increase the capacity of the power unit.

The invention is illustrated by description of its design and drawings, where

1 schematically depicts dam hydroelectric driven by river flow;

figure 2 is a view of A.

Dam hydraulic unit driven by river flow, contains supporting frame 1 with active turbine, made in the form of an endless conveyor placed across a river flow. The endless conveyor has two shafts 2 and 3, along the stream and covered by the flexible traction elements 4 and 5, made for example in the form of ropes or chains. Flexible traction elements 4 and 5 are interconnected with transverse supports 6. On the transverse supports (6) are fixed axis 7, which can be rotated set of blades 8. In the working position, the blades 8 are arranged at an angle to the direction p of the current and fixed relative to the transverse supports 6, for example, by bolting (not shown). Between the branches of the endless conveyor has a divider river flow, made for example in the form of a rectangular plate 9 attached to the side edges to the shafts 2 and 3, the endless conveyor by means of bearings 10. On the raw frame 1 posted by generator 11, kinematically linked, for example, chain transmission 12 with one of the shafts, an endless conveyor (figure 1 generator 11 is connected with the shaft 2).

Dam hydraulic unit driven by river flow, works as follows.

The support frame 1 through the floating tools or bottom of the Foundation (not shown) fixed in the river, setting an endless conveyor transversely of the flow of the current environment and aiming his shafts 2 and 3 along the stream. When the blade 8 is directed at an angle to the flow of the river.

The current environment acts on the blade 8, is fixed by the axes of the transverse supports 6, which connect between a flexible traction elements 4 and 5. The blades 8 under the influence of river flow begin to move, and flexible traction elements 4 and 5, covering the shafts 2 and 3, lead them into rotation. The blades 8, moving in areas of transition from one branch to another, are also involved in the work. The divisor of the river flow, in the specific example performed is output in the form of a rectangular plate 9, attached side edges to the shafts 2 and 3 by means of bearing supports 10, prevents the contact of the counter-directed flows generated during the movement of the blades 8 mounted on different branches of the endless conveyor.

Rotation of the shaft 2 through a chain transmission 12 is transmitted to the electric generator 11, converting the energy of the river flow into electricity.

The location of the shafts 2 and 3, the endless conveyor along the flow of the current environment and the installation of the blades 8 on the axes 7, mounted on the transverse supports 6, connecting the flexible traction elements 4 and 5, the endless conveyor, allows to achieve the maximum effects of river flow on all blades 8. Such fastening of the blades 8 on the flexible traction elements 4 and 5 allows to achieve participation in the work of the blades 8, moving in areas of transition from one branch to another, as their angle of inclination with respect to the stream remains unchanged.

In addition, the placement of branches at different levels in height allows you to extend the frontal impact river flow impulse turbine unit and the presence of the flow divider located between the branches, reduces the resistance to movement of the blades 8.

Compared with the prototype of the proposed invention allows to increase the total working surface of the blades, which acts on the OK current environment, to reduce the resistance to movement of the blades and to considerably increase the capacity of the power unit.
