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 vortex turbomachine, comprising a housing with inlet and outlet nozzles and swirl chamber, the impeller disk, the surface of which are arranged blades, the housing is equipped with a centrifugal spiral swirl open working channels from the side of the vortex chamber (see RF patent №2027892, IPC9F03B 17/00, F04D 17/06, publ. 27.01.1995,).

The disadvantages of this turbine are low efficiency and high consumption of water, due to the fact that the open channels of the swirl does not give the desired turbulence of the working fluid in the vortex chamber. The flow in the channels of the swirl is in direct contact with the working fluid of the vortex chamber, which reduces the pressure of the flow in the channels of the swirl, part of the flow without turbulence enters the vortex chamber. Due to the weak turbulence of the working fluid of the vortex chamber, the turbine has low power. For normal operation of such turbines requires the construction of a dam or diversion of water, which leads to higher prices of electricity.

Closest to propose the technical solution is a water turbine, containing horizontal cylindrical sectional-mountable chassis with working bodies in the form of a blade screws fixed on the shaft, and a mechanism for mounting a blade screws to the casing is installed with the possibility of rotation of the shaft (see application WO 2009/012977 (A2), IPC9F03B 3/04, publ. 29.01.2009,).

The disadvantages of this turbine are low power, low efficiency with a rather complex solution (regulation of blades angle of incidence of the stream). Within one section of the angle of incidence of the flow may be adjusted in the range from 0° to 90°, to the same part of the stream, swirling on the first screw will slide along the curves of the blades following screws that will lead to low power and low efficiency. Further changes in the incidence angle of the flow (decrease or increase) in the following sections reduces to "no" the first section, as the next direction of the swirling flow is opposite to the direction of flow in the cylinder. The entire turbine is possible when the angle of incidence of the flow from 0° on the blades of the first screw of the first section up to 90° on the blades last screw the last section, provided that twisted at the last screw thread will not be beat in the turbine housing. Here as part of the stream, swirling on the first screw will slide along the curves of the blades following screws that will lead to low power and low efficiency.

The technical result of the proposed technical solution is to simplify the construction and operation, to increase the capacity and efficiency of the turbine, its durability and lower cost.

The solution of the technical problem is achieved by the fact that the turbine containing a cylindrical sectional-mountable chassis with working bodies in the form of a blade screws fixed on the shaft, and a mechanism for mounting a blade screws to the casing is installed with the possibility of rotation of the shaft, according to the invention, each partition is installed blade propeller, the blades of which are made of the same curve to ensure a constant flow rate and synchronous operation of all blade screws and the clamping mechanism is located on the opposite side of the blade of the screw relative to the direction of flow while the turbine is equipped with stabilizers, thread, made in the form of sheet metal, one edge attached to the housing and a plane directed along the radius to the shaft along the body and stabilizing the stream coming from one screw to the next.

This device will allow 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, durability and to reduce costs.

The invention is singing the applicable drawings, which figure 1 shows a General view of turbines, figure 2 is a section along a-a in figure 1, figure 3 is a section along b-b In figure 1.

The turbine consists of a sectional-modular horizontal cylindrical body 1, the working blade of the screw 2 with the same bending of the blade, the clamping mechanism 3 of the screw 2 to the housing 1, stabilizers flow, in the form of metal sheets 4, shaft 5, on which is rigidly fixed to the screw 2. Horizontal cylindrical sectional-mountable chassis 1 is mounted on a concrete base 6 (see Fig.1-3).

The turbine operates as follows. Cylindrical sectional-fabricated turbine housing 1 is fixed on a concrete base 6 mounted on the side of the riverbed. The natural flow enters the housing 1 on the blade of the working screw 2 (see figure 2 are shown for illustration purposes only 3 blades work screw), rigidly fixed on the shaft 5, the blades spin flow and result in rotation of the screw 2. Swirling stream, after leaving the working of the screw 2, fixed to the body 1 by the mechanism 3 mounted with the possibility of rotation of the shaft 5, hits the metal sheets 4 is a flow conditioner with a certain angular speed, straightens up, and stable rectilinear flow goes to the next screw, then the cycle repeats. Since the blades of the working of the screw 2 are odinakovymi and therefore, the same angular velocity, within the housing 1, the flow rate will be constant (according to the continuity equation of flow rate), and all work 2 screws will work synchronously. Synchronous rotation of the screw 2 by means of shaft 5 through appropriate mechanisms (not shown in figure 1) is transmitted to the generator.

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

Turbine containing a cylindrical sectional-mountable chassis with working bodies in the form of a blade screws fixed on the shaft, and a mechanism for mounting a blade screws to the casing is installed with the possibility of rotation of the shaft, characterized in that each section is installed blade propeller, the blades of which are made of the same curve to ensure a constant flow rate and synchronous operation of all blade screws and the clamping mechanism is located on the opposite side of the blade of the screw relative to the direction of flow while the turbine is equipped with stabilizers, thread, made in the form of sheet metal, one edge attached to the housing and a plane aimed what about the radius to the shaft along the body and stabilizing the stream, coming from a single blade screws on to the next.
