The invention relates to hydropower installations using kinematic and potential energy moving in the rivers of water.

Famous modern hydropower plants containing large concrete dams, powerful hydraulic turbines, generators and other structures. However, these plants rely on only the potential energy of the water accumulated by raised, sometimes very high concrete dam, which in turn forced suppresses the kinematic energy of flowing water in the river, and large parts of its segment.

In addition, these hydroelectric power plants with high and low dams are environmentally harmful structures on the beds of large and small rivers.

Known the simplest type hydraulic motor loading wheel containing the shaft, spokes and rim, on which are mounted trough-shaped blades (see Physics. The textbook for 6th grade. 1973, S. 178). This motor is mainly used potential energy of the raised dam water. As mentioned above, has to be the same dam and the same inevitable troubles from the overlap of the riverbed.

However, the known device is not able to fully use the entire mass flow of water on the area covered by the installation, because a significant part of the energy of the flow of water extinguished the guide walls floats forming the input tapering channel.

For the same reason, the laminar flow of water in this area is transformed into a turbulent flow, which to some extent is not the best way affects the turbine blades.

Part of the energy flow is extinguished by jumper installed between floats, i.e., across the flow of water.

Cannot use the energy of the mass of water in case of rising above the optimum, which is designed for the installation.

The objective of the invention is the use as kinematic and potential energy moving by eng

This technical result is achieved in that run of river hydroelectric power plant, comprising a hydraulic motor, generators and the fastening elements in the soil of the bed of the river, according to the invention the actuator is made in the form of a hollow rotor, and the importance of its application in liquid medium flowing at a certain speed and direction, the actuator is a craft, performing both the role of the rotating dam, taking the pressure of water in the form of some roll on the craft, ribbed on its cylindrical part of the blades, for example, horizontal, kosolapogo (helical and herringbone locations, bent at an obtuse (Sov) angle on their cross section. To keep the craft to the location on his hollow half-dressed reference bearing pillow placed between the vertically installed and fastened in the soil of the bed of the river power supports, configured to move the cushions between the power jacks limited down and free up change induced water level in the river, and move pillows accompanied together with the bottom plate, with which the cushions are connected by rods. Come the level of the water. For communication and rotation boats with generators on each of the speakers into the opening of the cylindrical part of the craft hollow axle together and pivotally suspended from the gear involved splined connection with the axis of rotation, a counterweight and an electric generator, power cable which goes through the hole in the hollow axis, for his beyond the craft and to the consumer of electricity.

The above construction of hydroelectric power provides the opportunity for any level of water in the river to use a significant part of the kinematic and potential energy of moving water on the section of the river, leaving the rest of the river for the installation of a series of cascades environmentally friendly hydropower.

In Fig. 1 shows a General view of the proposed hydropower plant to partially cut the wall to better show the construction; Fig. 2 is a view of the power plant with its face side.

Hydroelectric power plant consists of a hollow cylindrical boats 1 made in the form of a rotor, finned working blades 2, and its end walls are installed and fixed hollow shafts 3, in which the outer side of the prisoners in the soil of the riverbed. Bearing pads are connected by rods 6 with the bottom plate 7. Each of the speakers into the opening of the cylindrical part of the craft hollow shaft 3 together and pivotally suspended from the gear 8, the counterweight mounting plate 9 and the generator 10, the power cord 11 which is pulled through the hole in the hollow axis 3 the end wall of the craft.

The hollow cylindrical portion of the watercraft 1 can be made of part of a pipe of a certain diameter and length, coated inside and outside concrete layer to give the trumpet a certain rigidity and weight, can immerse cylindrical portion boats under a certain water level. The same coating can be done with the bottom plate 7. Counterweights 9 may be made of any of heavier material, and the gear 8 and the generators 10 can be made of standard performances. Vertical supports 5 may be made of reinforced concrete piles hammered into the ground in a row. If necessary, dismantling hydro booster cushion can be released from the supports by diversion of one of the pairs of feet to the side. In this case, the hydroelectric power station is free to move through the water at a different place of work or is area this low-lying gap between the cylindrical part of the hydroelectric power station and stove, the height of working blades must match the size of the height of the slit. Balances axis 3 should have 2-, 3-fold resistance to torsion of the suspension around the axis of rotation 3. This takes into account the maximum possible load on the generator, amplifying the torque of the suspension.

The length of the cylindrical part of the hydroelectric power station designed for installation on large and deep rivers, is determined by the width of the active flow of water in the river, if the width of the active flow will be significant, the cylindrical portion is performed by separate sections. For example, at the turn of the river, the slopes of the terrain and other areas, while the rest of the plot "quiet water" can be used for the passage of water transport and other possible needs. The diameter of the cylindrical part of the hydroelectric power station is determined based on the depth of the active layer of the water flow on the selected for installation of the power plant section of the river, taking into consideration the height of the tumbler of water on the cylindrical part of the hydro. Immersion of the cylindrical part along with a tumbler of water should not be more half the height of its diameter.

The proportionality between the size dvetsa with a water flow rate of the selected section of the river, creating a certain height of the tumbler of water on the cylindrical part of the hydro.

On one of the end walls of the cylindrical part hydroelectric made the hermetically sealed Assembly, depending on the installation and maintenance of the equipment installed inside the craft.

Set 4 pillows floating in my power support is effected by means of a long rope, one end of which is pinned to pull the fixture on a support cushions 4 and the second ends of the cables should be secured to the opposite sides of the river channel from the source water with the possibility of winding and release cables.

The craft 1 is slid to his workplace by careful grazing cables in the course of flow of water in conjunction with the craft. Early release one side, putting the craft under a certain angle, and then the second side of the craft. When the cushions 4 will be installed in its place and fixed operational fixed thrust 6 to the bottom plate 7 and the power cable to the line of electricity consumption. Dimensions length rod 6 is regulated by the free passage of water in case of a large rise in water level in >This means, when rotated the craft around its axis, secured to the support bearings, at the same time, all the suspension gear 8 through its and extra weight is vertically suspended on hollow shafts 3 boats 1, and since this axis is fixed to the end wall of the watercraft and associated splined connection with the toothed gear of the first stage increases the speed reducer 8, this toothed gear on its ordinal levels increase the speed passes the rotation axis 3 boats on the generator 10, which is subject to the availability of load produces electricity for use by the consumer.

Hydroelectric power plant in the form of a rotating rotor craft, equipped with working blades and converters mechanical energy into electrical energy through moving water in the river can be installed on full-flowing rivers, and moderate fullness of water, but relatively tangible over and, of course, on the rivers with the powerful and turbulent flow, albeit with changing water level in the riverbed. This allows you to use a significant portion of the energy resources of all able to do this, rivers and refuse postrace needs of the national economy.

The proposed plant can be made of sheet or strip steel by special Assembly areas located near the river, and then launched, they can be transported by water to the place of destination, and the place is brought to full completion of all installation work. In short, the cost of the construction of the proposed power plants will not require large expenditures of funds and materials for craft in comparison with the known power plants. They can be established for an indefinite stations along the stretch of the river, bringing the energy to the consumer. Especially in the regions of natural resource remote from populated places. They can work in harsh winter conditions due to its own heating of some structural elements of the craft.

The economic advantage of the construction of the proposed hydroelectric obvious and promising.
