The invention relates to devices designed to convert the energy of the water flow of the river into electricity.

Known HES a new type that contains a dam with pump, pumping water from the river through a pipeline into the drive, made in the form of the basin, which is located above the level of the river, and the piping used to drain water from the drive to the turbine generator (see "journal of the Inventor and rationalizer", N 8, 1991, S. 14, and avresti natural regime of the river and great expenditure of funds for its construction and operation.

Known hydropower plant containing at least one pump for pumping water from the river through a pipeline into the drive, situated above the level of the river, and the rotation of the pump is provided with a hydraulic motor, made in the form of endless chains and flexible elements with blades, covering the head and tail pulleys, while the blades of the lower branches of the flexible elements and the shaft tail pulley with its bearings immersed in the water flow so that the direction of movement of the lower branches with blades relative movement direction of the water flow forms an angle greater than the direction of movement of the upper branches.

The disadvantage of this HPP is the low efficiency and short life its working body, i.e., the flexible circuit elements.

This is because the contact with the water flow of the river, the lower branches of the flexible elements with blades and shaft tail pulley of the working body leads to an increase in resistance as it rotates without load and intense corrosion, and thereby reduce the efficiency and durability of his work.

In addition, the location of the lower branches of the flexible elements in the water flow of the river at a large angle to the direction of water flow contributes to the force of the water flow razloga in the direction In acts parasitic, i.e. useless tension of the flexible circuit elements, moreover, not only the lower branches, but also top - off branches, and this leads to increased friction hinge joints flexible elements is directly proportional to the force of the water flow.

This contributes to the fact that the fulcrum is made near the axis of rotation of the blade, limiting the rotation of the blade, and swivel the blade with a flexible element located near each other and on the same flexible element also acts on the chain tension, and with the repeated force of the water flow due to the difference between the shoulder blades, which constantly tend to rotate the flexible element around the axis of the blade and thereby hold the chain in constant tension.

The objective of the invention is to increase the efficiency of hydroelectric power and increase the longevity of its working body.

This technical result is achieved due to the fact that there are hydroelectric containing at least one pump for pumping water from the river through a pipeline into the drive, situated above the level of the river, and the rotation of the pump connected to the hydraulic motor, made in the form of endless chains flexible elements with blades, flexible elements, in turn, provided with a guide, providing the bodies of the rolling movement of the scooter: the upper branch from the top dead center - TDC tail pulleys, to the bottom dead point - NMT head pulleys, and the lower branches of the flexible elements from the NMT pulleys, to NMT tail.

Moreover, the angle of the lower branches of the flexible element relative to the movement direction of the water flow can be set to the lowest, than the angle of inclination of the upper branches, but providing for movement of the rolling elements along the guides of the scooter, and the blades of the lower (working) branches flexible elements are immersed in the water flow of the river so that the area of the contact surface of the front of the blades, located at the head pulley, less than the area of the contact surface of the blades tail pulleys, and is not in contact with the water flow of the river infinite chain of flexible elements with the rolling bodies and shafts of tail and head pulleys and their bearings.

In addition, to reduce friction hinge joints flexible elements as the working and idle branch, the axis of the blade can be equipped with brackets that hold the blade at a distance from the axis, and occasinaly that each of the latter pivotally connected at one end to the EMA hydropower; in Fig. 2 - section gear pump, to better show the path of water flow therein; Fig. 3 - node I in Fig. 1.

Hydroelectric contains at least one pump 1 for pumping water from the river through a pipeline 2 into the drive 3, located above the level of the river at the height of the required power discharged from it the water flow, the hydraulic motor 4, the working body of which is made in the form of endless chains flexible elements pivotally connected with them blades 5, covering the head pulleys 6 and tail pulleys 7, forming two branches: single (upper) and working (bottom). The axis 8 of each of the blades are provided with arms 6, each of which is rigidly connected with it and keeps the blade at a distance from the axis. Otkazini 10 pivotally connected at one end with the bracket 9, and the other with the axis 8 of the previous blades 5. In addition, both branches of the working body provided with a guide rail 11, and the axis 8 of the blades 5 - 12 tel rolling on them, with each branch of the flexible element is located at an angle to the horizon with the possibility of movement of the rolling bodies scooter and, thereby, rotation of the hydraulic drive water flow of the river he has no resistance to the water flow, in addition to lifting 3-4 blades at the height of the wires 13 and line 14, serves for draining the water flow to the turbine of an electric generator hydro-15. If necessary, the pipes 13 and 14 and the storage capacitor 3 can be provided with elements heat them in the winter time, for example the duct 16 and the insulation layer 17 with a casing 16, with the possibility sectional Assembly them connected with a source of warm air, located, for example, in the premises of HPP-15.

This hydroelectric power plant is as follows.

The hydraulic motor 4 their blades 5 working branch takes the full force of the pressure of the water flow occupied the area of the river and the rotating shaft of the pulley 6 PTO hydraulic, United as needed through the gearbox or without it, with the pinion 19 of the pump 1, passes it the rotation of the driven gear 20, and the whole force of the pressure of the water flow goes to the rotation of the pump 1, but lost the strength that is needed on the rise three blades 21, 22, 23 located on tail pulleys 7, because the rest of 23 of the blades (see Fig. 1) move on going 11 scooter. A working branch of the flexible elements of the hydraulic motor 4 through the guide 11 moves rectilinearly and parallel to it, and thus does not create the chain tension the flexible element x is resistance from the force of the tension, as is the case in the prototype, from the location of the working branch at a large angle to the direction of movement of the water flow and the location of the poles of the blade near the center axis of its rotation. In the proposed for preventing rotation of the blade 5 around the axis 8 support is otracina 10, which, taking some of the force of the pressure of the water flow coming in to the area of the blade 5, and transmits it to the axis 8 of the previous blade, thereby retains the straight-ahead position of the flexible element and using the guide 11 rectilinear movement, which helps to eliminate tension idle branch of the working body, under no load, and thus increase the service life.

Economic efficiency is that with increasing longevity of the working body of the hydroelectric power plant and increase its capacity opens the way for its use in the mass and thus humanity will be able to get rid of the use of environmentally harmful methods of production, the necessary amount of electricity, such as nuclear power plants.
