The invention relates to hydropower and can be used for electricity production on small rivers.

Known SHP with active turbine (EN 2305793, IPC F03B 13/00 2006.01, EV 9/00 2006.01). HPP is designed to generate electricity using the power of the flow of a stream or river. HPP includes the dam water intake, cone intake, penstock, the impulse turbine (AT), the current generator to the actuator. Cone (K) of the intake performed only in the horizontal plane, the entrance of the bottom outlet and the entrance To conduit are situated in one plane and above them on the crest of the dam water intake installed a warm room, a wall which faces the reservoir is located behind the dam, and its lower edge recessed on the amount of freezing water reservoir. AT made in the form of a disk with buckets in the form of snails. Each nozzle pressure conduit made as To associated with the valve pressure conduit via an intermediate conduit. As the brake system to stabilize the speed AT applied additional DC generator, the shaft of which is connected with the shaft of the main generator (DG) and the field winding through a diode bridge is supplied current from a three-phase network the EXHAUST gas. In addition, in the control circuit of the excitation winding of the EXHAUST gas applied to the rheostat driven centrifugal tolgate who eat for example, the system of the vehicle, which shaft is also connected with the shaft of the EXHAUST gas. The construction HPP provides increased power and constancy of the frequency of the current.

Specified has similar disadvantages. It utilizes the expensive design, difficult to install and manufacture, working only in a fixed state, not taking into account the water level in the reservoir. When hurricane rainfall, debris flows, excessive movement of the water flows of logs, boards, trees, pieces of metal, stones and other things, it fails.

The closest solution to the claimed technical solution is hydroelectric containing floating fixed cables with supports on the shore, a turbine with straight blades, the shaft of which is mounted in the bearings, with the possibility of vertical movement, kinematically connected with the generator, and start-regulating equipment, hydroelectric contains one row or more turbines installed on the hollow platforms in parallel, on the shafts of the turbines are mounted sprockets connected by a chain, with the boats ahead rigidly fixed lattice in the form of a wedge (DE 814879 AND 02.08.2951, F03B 17/06) prototype.

The prototype has the following disadvantages:

- generator and drive sprocket located inside one of the two hollow, open top boats. In the case there is no protection of vessels from entry of rain and river water and the integrity of the electrical equipment, that with high probability will lead to corrosion of equipment, and possibly to accidents;

grill for removal of garbage is mounted in a single design platforms hydroelectric, its rigid attachment to them hinders the smooth allocation of floating debris and will certainly lead to its accumulation on it, which will considerably reduce the pressure and rate of flow of water flowing through it to the turbine. And in case of a critical accumulation of large debris on the lattice can occur and tilting the whole structure;

- straight profile and the angle of the edges of the turbine blades obstruct the entrance of the latter into the water, thereby reducing the turbine efficiency.

The objective of the proposed technical solution is to eliminate the disadvantages inherent in the prototype, namely improving the efficiency of the turbine by optimizing the entrance of her blades in the water flow and increased power flow, the more efficient the filter is to prevent the accumulation of floating debris and tap it into the side of hydroelectric power plants, improving the safety of operation and maintenance of hydroelectric power.

The technical essence of the proposed solution lies in the fact that hydroelectric power plant, representing floating fixed cables with supports on the shore containing one row and more turbines in parallel, set the run on the hollow platforms turning into sharp edges vertically in the bow, the shafts of which are mounted in bearing supports with the possibility of vertical travel and kinematically connected with the generator and motor-starting equipment, turbine shafts are mounted sprockets connected by a chain, and before the craft is a filter in the form of a wedge for removal of items (logs, planks and the like)that is different from the prototype in that the turbine blades are sickle-shaped profile and fixed to the chassis of the shafts so that their edges to form a water acute angle, hollow platform are cross-sectional trapezoidal shape, turning into sharp edges vertically at the rear side, vertical racks, the filter still at a distance from the craft, fitted with castors with possibility of rotation, and the generator and start-regulating equipment installed on the shore.

The essence of the invention is illustrated by drawings, where

1 shows a hydroelectric power station, view from above;

figure 2 shows a hydroelectric power plant, side view;

figure 3 shows a hydroelectric power station, front view.

Hydroelectric contains craft 1 (2), fixed with 2 cables with supports on the shore 3, a turbine 4 (Fig 1), the shaft 5 which is mounted in bearing supports the x 6 (figure 2) and all of them together have the possibility of vertical movement due to the hollow platforms 7(3), when changing the water level. The craft 1, kinematically connected to the generator 8, which in turn is electrically connected to motor-starting equipment 9. Turbine 4 is equipped with blades 10 (figure 2), with sickle-shaped profile and fixed to the chassis 11 of the shaft 5 so that their edges 12 to form a water mirror 13 acute angle (Fig 3). Turbine 4 is installed on the hollow platforms 7 in parallel, at a distance restore energy flow of the water consumed on the previous drive turbines. On the shafts 5 turbines 4 are mounted sprocket 14, interconnected by chains 15, and a hollow platform 7 are cross-sectional trapezoidal shape, turning into the nose 16 and back 17 parts in a sharp edge 18 vertically (figure 1). Before craft 1 at a distance outlet installed large objects fixed filter 19, in the form of a wedge, vertical posts 20 which is equipped with rollers with the possibility of turning to prevent the accumulation of floating debris on the fixed filter 19. The drive sprocket 14 of the turbine 4 through bearings 21 and 22 and extends cardan axles 23 and 24, connected to a generator 8 connected electrically with the motor-starting equipment 9, which is also connected to the consumer 25.

The power plant operates as follows. At installation of a hydroelectric power station on the river is selected Udo is Noah for its installation place. To narrow down the riverbed and generator protection and ballast equipment from floods edge of the banks of the concrete (figure 1). Next, on the opposite shores of the installed concrete pads 3, for securing the watercraft 1 with 2 cables. The generator 8 and start-regulating equipment 9 are set on the shore and tied with craft 1 with lengthening cardan axles 23 and 24. During storms, hurricanes, mudslides, etc. fixed filter 19 in the form of a wedge protects the hydroelectric power plant from mechanical damage, as larger items he takes her to a party by a twisting roller, which is provided with vertical rack 20, and they pass by the watercraft 1. Streams of water falling in the target vessels 1, constrict, accelerated, and, pressing on the blade 10 of the turbine 4, lead the latter into rotational motion. The speed of water flow is lost, but over time the rate of water flow again and at this point the water flows again in contact with the turbine blades and bring them into rotational motion. Turbine 4 are located at a certain distance to ensure that water is managed to restore the flow velocity. And the blades 10 turbines 4 have sickle profile for easy entry into the water.

The flow of water 13 entering the area between the sharp edges 18 and t is pareidolia hollow platforms 7 boats 1, is compressed, increasing its level and increases its speed. The lower half of the turbine 4 are in the flow of water under pressure for forming the profiles of the blades 10 start at the same time to rotate. As on the shafts 5 and all turbines 4 fixed sprocket 14, and they, in turn, are connected by chains 15, the pivot point of the rotational motion from the turbine 4 is transmitted through a system of sprockets 14 and chain 15, the uprights 21 and 22 and extends cardan axles 23 and 24 to the generator 8, which is mechanical energy into electrical and transmits it to the consumer 25 through gear equipment 9.

This raising or lowering of the water level 13 does not affect the operation of the turbines 4, because they are by flexible cables 2, the supporting pillars 3 and the hollow platforms 7 are constantly at the same level of immersion in the flow of water. This allows you to rotate the turbines 4, on average the same speed.

Large objects, logs, planks, sticks, pipes etc., removed by water flow, diverted away from the watercraft 1 filter 19.

Thus, the proposed solution allows to solve the following tasks.

The blade 10 with a broad profile, fixed to the chassis 11 of the shaft 5 so that their edges 12 to form a water mirror 13 acute angle (Fig 3), smoothly and with less effort are in the water, do not cause the tremors and increase the efficiency of hydroelectric power.

Trapezoidal shape hollow platforms 7, turning into a sharp edge 18 vertically at the rear 17 of the part, can significantly increase the rate of water flow through a narrow duct, thereby increasing efficiency and eliminating turbulence at the output by increasing the flow of water leaving the craft 1 through sharp edges 18 vertically at the rear 17 of the part.

Vertical posts 20 of the filter 19, is installed separately from the boats, snabgenie rollers with the possibility of rotation, allow you to freely take any floating debris on the sides of the watercraft 1, without causing tipping of the structure, protecting it and the turbine 4 from mechanical damage, which in turn improves the reliability, capacity mechanisms and ensure uninterrupted supply of electricity.

The design of the watercraft 1 with turbines in the proposed implementation eliminates the need to build expensive structures to create artificial differences and systems of water supply to the turbines.

Due to the complete rendering of the electrical equipment outside the water flow and disposal of large items fixed filter 19 in the form of a wedge, in which the upright support 20 provided with elongated rollers with the possibility of twisting, the proposed solution provides the stability and security of supply is of.

Thus, the technical problem is solved by new signs proposed by us.

The implementation of the technical solution is not particularly difficult, given the above, all base nodes boats will be manufactured in their own production.

Hydroelectric representing floating fixed cables with supports on the shore containing one row and more turbines are installed in parallel on the hollow platforms, turning into a sharp edge vertically on its nose, the shafts of which are mounted in bearing supports with the possibility of vertical travel and kinematically connected with the generator and motor-starting equipment, turbine shafts are mounted sprockets connected by a chain, and before the craft is a filter in the form of a wedge for removal of items (logs, planks), wherein the turbine blades have sickle profile and fixed to the chassis of the shafts so that their edges to form a mirror of water an acute angle, and a hollow platform are cross-sectional trapezoidal shape, turning into a sharp edge vertically at the rear side, vertical racks, the filter still at a distance from the craft, fitted with castors with possibility of rotation, and the generator and pushresult the equipment installed on the shore.
