The invention relates to hydraulic turbines operating on natural energy of water flow at different speeds and capacities, and can be used in industrial electricity without building dams and derivation of water.

Known turbine is improved by Pelton in 1860 and contains wheel-rotor, which is fixed to a few blades of buckets contained in the work tight with a water jet from a nozzle (see Twywell J., The Weir A. "Renewable energy sources", M., Energoatomizdat, publ. 1990, s).

The disadvantages of this turbine are low power due to the fact that the blades buckets when entering into a jet of water meet great resistance, which reduces the work of the previous blade. When moving blades of a jet of water goes under the blade, leads to unnecessary consumption of water and therefore reduce efficiency. For operation of the turbine of the Pelton necessary artificial water pressure and, consequently, the construction of a dam or diversion of water, which increases the cost of electricity and leads to further environmental consequences.

Closest to the proposed technical solution is a hydraulic turbine with vodovodom comprising a horizontally positioned rotor blades (see patent RU No. 2146336, IPC8F03B 1/00, publ. 10.03.2000,).

The disadvantages of PR is the totype are the complexity of the design, low power, because with the entry of the blade into the discharge flow of the subsequent plane of the blade is located at an angle above the plane of the pressure flow, and the previous plane of the blade at an angle below the plane of the flow, i.e. the power pressure flow will act simultaneously in two opposite directions with different values and, therefore, one blade will reduce the work of another. When the blades are inevitable loss of energy flow, which reduces the efficiency of the turbine. The need to create artificial pressure results in high costs for the construction of dams, the derivation of water and environmental degradation, namely zablakavanasci soils, high ground water levels, etc.

The technical result of the proposed technical solution is to simplify the fabrication and operation, improving the capacity and efficiency of the turbine, the efficiency of use of water resources of rivers, reducing the cost of electricity, improvement of ecological situation, as well as increased durability.

This technical solution is achieved in that the known hydraulic turbine comprising a horizontally positioned rotor blades, according to the invention the rotor and the blades are made teams, while the rotor is constructed in the form of two semi-shafts with drive and SN is been two lateral contour discs and the blades are made in the form of V-shaped plates located around the circumference of the disk tore the rotor and provided with metal plates rigidly connected to the sides of the V-shaped plates, corners and tight gaskets, and on the lateral contour of the rotor disk area is fixed, at least one second sheet metal blades, and sealing gaskets made in the form of annular shape, are from tore the rotor to mount the V-shaped plates to the metal sheet, and rectangular - under the corners, between the V-shaped plates and the metal sheet.

This device allows to simplify the design and operation, to increase the capacity and efficiency of the turbine, to increase the efficiency of use of water resources of rivers and durability of the turbine.

The invention is illustrated by drawings, where figure 1 shows a General view of the rotor-section 2 - section a-a in figure 1, figure 3 - turbine is in the working position, mounted on a concrete base and supports (front view)figure 4 - side view.

Hydraulic turbine consists of a modular rotor, made of two semi-shafts 1 with 2 disks and two lateral contour of the disks 3 and team blades made in the form of V-shaped plates 4 located around the circumference of the disc 2 tore the rotor side which rigidly connect the modern metal sheet 5 (see 1), and at least one second metal sheet 5 of the blade 4 is fixed parts 6 on the lateral contour of the disks 3 of the rotor (see figure 2). As the fastening elements 7 are used, for example, bolts (see figure 2, 4). Sealing gaskets 8 are in the form of annular shape and are from tore the rotor to mount the V-shaped plates to the metal sheet, and rectangular - under the corners, between the V-shaped plates and the metal sheet.

The rotor of the hydraulic turbine palavalli 1 installed on two concrete supports 9 with vertical guide slots 10 and mounted on the concrete base 11 side of the river channel (see figure 3, 4).

Hydraulic turbine operates as follows. The natural flow of water passing through the concrete base 10 part of the river falls into teams of blades 4, 5 turbine, which perform the function of the shaft. The energy of the translational motion of the stream is converted into the energy of rotational motion of a modular rotor 1-3 (see figure 1, 4), which by means of mechanisms (figure 3, 4 not shown) is transmitted to the generator. In operation simultaneously includes multiple blades, which increases the power turbine. Since turbine has a rigid hermetically closed space due to tight gaskets 8, it is able to operate at any power load is.

The use of the proposed hydraulic turbines will allow for a comparison with the prototype to simplify the design and operation, increase its capacity and efficiency, as well as the efficient use of water resources of rivers, to reduce the cost of electricity and improve the environment.
