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 unit, which is driven by the flow of the current environment containing a floating base in the form of a catamaran, which is fixed to the active turbine, made in the form placed oblique to the flow of the current environment 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 (see the description of the invention to the patent of Russian Federation №2269672, Appl. 17.06.2004, publ. 10.02.2006, CL F03B 9/00).

Since the formation of the power unit involved not only the flow velocity of the current environment, but the total area of the working bodies of the turbine affected by this stream, known power unit does not take all the energy of the current environment, first, his endless belt is conveyor is at an angle to the flow and secondly, it has a single branch is not involved in the work.

The closest to the essential features of the claimed (prototype) is the dam unit for recycling the flow of the current environment, containing supporting frame with active turbine, made in the form of an endless conveyor placed across the flow of the current environment and having two shaft covered by a flexible traction element with blades arranged at an angle to the direction of flow, sliding bearings, interacting with the guides of the supporting frame, on which is placed an electric generator, kinematically associated with one of the shafts, an endless conveyor, the rollers of the endless conveyor arranged transversely of the flow, the support frame has at least two pairs of rails, and sliding bearings interacting with the guides located on the front and rear side edges of the blades (see the description of the invention to the patent of Russian Federation №2166664, Appl. 19.06.2000, publ. 10.05.2001, CL 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. Furthermore, the presence of at least two pairs of rails on the side edge of the blade, interacting with two pairs of sliding bearings, greatly complicates the design and increases the resistance to movement of the endless conveyor.

The problem to which the present invention is directed, is to increase the total working surface of the blades, which affects the flow of the current environment, to reduce the dam unit number of moving joints and to simplify the design that will significantly increase its capacity.

The problem is solved in that in the dam unit for recycling the flow of the current environment, containing supporting frame with active turbine, made in the form of an endless conveyor placed across the flow of the current environment and having two shaft covered by a flexible traction element with blades arranged at an angle to the direction of flow, sliding bearings, interacting with the guides of the supporting frame, on which is placed an electric 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 flow, and transverse support elements connecting the flexible traction elements, thus moving the support mounted on the flexible traction elements, and lo the Asti mounted on the transverse support elements.

The location of the shafts, an endless conveyor along the flow of the current environment and install it blade by means of transverse supporting elements connecting the flexible traction elements of the endless conveyor, results in an increase of the total area of the working bodies of the impulse turbine as the blades on the areas of transition from one branch to another are also involved in the work.

The distribution of sliding supports for flexible traction elements can reduce the number of bearings, to reduce the resistance to movement of the endless conveyor and to simplify its design.

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

1 schematically depicts a dam unit for recycling the flow of the current environment;

figure 2 is a view of A.

Dam unit for recycling the flow of the current environment contains supporting frame 1 with active turbine, made in the form of an endless conveyor, placed across the flow of the current environment. The endless conveyor has two shafts 2 and 3, located along the flow of the current environment and covered two flexible traction elements 4 and 5, made for example in the form of ropes or chains. Flexible traction elements 4 and 5 are interconnected by means of transverse supporting elements 6, with fixed blades 7, placed at an angle to the management stream. An endless conveyor is provided attached to the flexible traction elements 4 and 5 sliding bearings 8, interacting with the guides 9 of the supporting frame 1. On the raw frame 1 posted by the generator 10, the associated actuator 11 with the drum 2 of the endless conveyor.

Dam unit for recycling the flow of the current environment is as follows.

The support frame 1 through the floating tools or bottom of the Foundation (not shown) fixed in the river, having an endless conveyor transversely of the flow of the current environment.

The current environment acts on the blade 7 mounted on the transverse support elements 6, which connect between a flexible traction elements 4 and 5. The blades 7 under the influence of flow begin to move, and flexible traction elements 5 and 6, covering the shafts 3 and 4, lead them into rotation. The blades 7, moving in areas of transition from one branch to another, are also involved in the work, as their inclination in relation to the stream remains unchanged.

Rotation of the shaft 2 through the actuator 11 is transmitted to the generator 10 by converting the energy of the flow into electricity.

The location of the shafts 2 and 3, the endless conveyor along the flow of the current environment and the fixing of the blades 7 on the flexible traction elements with transverse supporting elements 6 gives the opportunity to increase obsolesced impulse turbine, interact with the current environment, due to the blades 7, moving in areas of transition from one branch to another, which also participate in the work.

The placement of the sliding bearing 8 on the flexible traction elements 4 can reduce the number of bearings, to reduce the resistance to movement of the endless conveyor and to simplify its design.

Compared with the prototype of the proposed invention allows to increase the total working surface of the blades, which affects the flow of the current environment, reduce dam in the unit number of the sliding connections and simplify its design that makes it possible to significantly increase the capacity of the power unit as a whole.
