The disadvantage of this setup is that the working body (shoulder blade) is placed on a roller chains, between which there is no sheathing, which will result in a very low efficiency, since the power flow Badolato energy flow pressure.

In accordance with this invention is based on the task to increase the capacity and efficiency of the hydropower plant.

This object is achieved in that famous hydropower plant, containing a working member made in the form of a hub with a drive sprocket, an endless chain, interacting with stars, devices, chain tension, main blades mounted vertically relative to the flow and pivotally mounted on the chains can move along the stream under the influence of the latter, and a device for attaching a working body, according to the invention, equipped with a rectifying shield placed in front of the screed in the course of the stream, the working body is provided with extra blades arranged at an angle to the main, the upper and lower flat bases elliptical shape with elliptical openings and a closed casing, installed between the bases and having a cross-section parallel to the bases, the elliptical device for attaching a working body in the form of anchor piles, on which, by means of bearings fixed to the hub of the drive sprocket, and a device for tensioning is made in the form associated with one of episodesthe with chains, each pile is placed in the openings, the base ends of each of the main blades installed bearings in contact with the grounds, but the chains are located on the outer shell.

In comparison with the prior art, the claimed invention allows to increase the capacity and efficiency of the hydropower plant at the expense of maximum energy flow pressure.

The invention is illustrated by drawings, where Fig.1 shows a hydropower plant in the cross section of the river from the side of the counter-flow (on the left side of the drawing, the main blades are not shown); Fig.2 - section a-a of Fig. 1; Fig.3 hydropower plant in a perspective view; Fig.4 main blade in axonometry.

Hydropower plant includes a submarine and surface parts (Fig. 1). The underwater part contains the working body, the main blade 1 which is provided with extra blades 2 arranged at an angle to the main blades 1, and placed at the same distance from each other, and a device for attaching a working body, made of the support 3 and the stretch 4 piles. The main blade of the working body are mounted vertically relative to the flow ivcol 12, installed between the base 17 and having a cross-section parallel to the bases, the shape of the ellipse. Hydropower plant installed at the straightener shield 5. When mounted between the supporting piles 3 to install diagonal or transverse concrete construction to ensure rigidity and stability of the hydropower plant.

To support the pile at 3, which is mounted surface portion of the gear 6 and the power generator 7, set 8 sprockets of the working body. To install them on the extreme anchor pile 3 is worn powerful metal (or other material) pipe 9, in the role of a hub, a driven sprocket 8. Inside the pipe 9 are mounted bearings (not shown) that are directly put on the extreme anchor pile 3. The pipe 9 is mounted on religiony bearing (not shown), which is located at the bottom of the extended portion 10 at anchor piles 3. The tension of the pile 4 are mounted idler 8 (similar piles 3). Drive and idler sprockets 8 are covered by the endless chains 11, for example a ship's circuits or the circuits of another type, with tension pile 4 plays the role of a tension of the endless chains 11. B is t-closed surface, having in cross section the shape of the ellipse is located on the inner forming tool and is designed to retain the water flow on the working surface of the main blades 1. Alternatively, an endless chain 11 can be mounted coaxial with the location of the edges of the main blades 1, or offset, as shown in Fig.1.

The main blade 1 to the endless chains 11 are mounted so that the resultant force F (summand on the direction of the water flow of the river 13 and the flow direction 14 discharged from the straightener shield 5) impacted on the working surface of each of the main blades 1 and for each main blade 1 does not overlap the working surface of each previous main blade 1 against the force F. in Addition, the main blade 1 has a metal (or other material) focus 15 to ensure its stability during the stroke, and contrary 16 to prevent rotation of the main blades 1 at idle it back on reaching the main blade 1. The main blade 1 during their work moved between the upper and lower base 17 along the inner and outer forming a working body. The upper and lower base 17 are made in a V is e 17 attached to all the piles 3 and 4 (not shown) parallel to the bottom base. In turn, piles 3 and 4 are installed in the openings of the base 17 in parallel forming a closed shell 12.

The distance between the upper and lower base 17 is equal to the height H of the main blades 1 together with the bearings 18, and the bearings 18 are in contact with the base 17 (top and bottom) and are mounted to each primary blade 1 sparano on top and bottom. The bearings 18 moves the main blades 1 between the upper and lower base 17.

Lubrication for all moving parts in the water is water. For normal operation of the hydropower installation endless chains 11 are located on the outer shell 12 and must be strained. To tighten or loosen the chain 11 is used tension pile 4, which moves in the upper part of the window mount shelf 19 and bottom 20 in parallel. Easing tension the conveyor chain 11 is made of a tension device 21 (type "hitch" or other). For tensioning the traction chains 11 it is necessary that the casing 12 and the upper and lower base 17 on both sides of the tension piles 4 had a break of continuity with the provision of overlapping their ends in the direction of the main blades 1. Tension device 21 is installed between the support 3 and the nut is STI: first, mount the bottom of the pile, the working body with its mobile system, representing the main blade 1 and the conveyor chain 11, and then the upper part is the gearbox 6 and the current generator 7, which are located on the shelf 19.

Straightener shield 5, playing the role of a local dam, narrow river channel, resulting in ground water discharge 22 from the straightener shield 5 on the main blade 1, the rate of flow and pressure of flow will increase. For effective operation of the hydropower installation be sure to install straightener shield 5 with the direction of the water flow of the river 13.

As a result, the greater the rate of flow of water and the more working level of the river, the stronger will be the hydropower plant.

To determine the operating level of the river "to" must have the following data:

""working level of the river, is equal to the height of the main blades Hltogether with the bearings 18 plus twice the thickness (2 t) of the upper and lower bases 17, i.e., Hl+2 t;

"a" is the amount equal to the maximum thickness of the freezing of water in the river plus 10-15% i.e. (a + 0.15 a);

"in size, taken from 0.2 to 0.5 m depending on the species or material constituting the bottom of the river;

"h" is the difference between the maximum water level in the river (pavetta features of the river.

Installation of hydropower plants for all, including the freezing of rivers, is as follows.

To the pile or pillar bridge 23 (or other piles not shown) secures the mounting shelves 19, where and going underwater and above-water part of the hydropower plant (on both sides of a support 23 or on one side), or with a small surface vessel or barge in places of rivers, not hinder navigation.

Hydropower plant works as follows.

To operate the hydroelectric installations that use the energy of the flow (flow) of water in the river using a straightener shield 5.

In order for the system main blades 1 effectively and in a given direction 24 is rotated, it is necessary at a height of Hyequal to NyHmin+ hp+ hG. T.where hpthe height of the reducer; hG. T.the height of the current generator, install and secure to the supports (in the drawings, they are not shown) from the side of the river 13 straightener shield 5, which can be manufactured from metal, concrete or other materials. You want the wings straightener shield 5 directed the stream of water directly on the next major Lopatka main blades 1, made in the cross-section in the form of an elongated ellipse, is a kind of continuation straightener shield 5 and the narrow river channel. As a result, the work will be part of the maximum energy flux (flow) of water, which is a great advantage, because it will increase the capacity and efficiency of the hydropower plant.

Under the action of water flow will begin moving main blades 1, through which the conveyor chain 11 transmit rotation of the drive sprocket 8 and the last transmit rotation to the gear and the power generator 7, which will generate electricity as needed by the consumer.
