The invention relates to hydraulic machines with movable shutters using the fluid flow, and can be used as turbines hydroelectric small power.

Known turbine, comprising a housing with end caps, inlet and outlet fittings are accommodated in the housing, the rotor with movable plates, one ends of which are pivotally attached to the rotor, and a streamlined guide (Patent No. 2147078, MKI F 03 In 17/06).

However, in this design of the turbine, which uses two rotors in a single unit, not fully implemented its capabilities. So when the flow of water through the turbine (pressure constant), you cannot use the full capacity and to ensure maximum efficiency. The change of torque in the turbine depends only on the pressure of flowing water.

Known turbine, comprising a housing with end caps, inlet and outlet fittings are accommodated in the housing two rotors and a streamlined guide (Patent No. 2191919, MKI F 03 In 17/06 - prototype).

However, this turbine has a movable plate, fixed on one side of the hinge on the rotor, with the other using pins that are installed in the slots of the housing. The making of such plate designs require great accuracy and complexity, the design of the turbine is SL the author.

The invention is directed to solving the problem of simplifying the design of the turbine, reducing labor for its production.

This is achieved in that the rotor is made of a pipe having a longitudinal cut and installed so that the pipe piece played the role of the plate, and the other part - the rotor housing, it is equipped with an additional system, including pump, switchgear and pipelines, ensuring that the water pressure in the subsequently formed cavities between the plates and the casing, and the casing of the turbine has two bracket from the intake port to support pipe.

The invention is illustrated in the drawing, which shows a General view of the turbines in the section.

The turbine includes a housing 1 with end caps 2 (in the drawing is only visible back cover), the inlet 3 and outlet 4 tubes accommodated in the housing 1, the rotor 5. The rotor 5 is made of a pipe having a longitudinal cut, and installed so that the inner part of the pipe played the role of plate 6, and the other outer part of the rotor body. Between the plates 6 and the housing 1 is formed of water-filled cavity 7, and between the rotors 5 are streamlined guide 8.

On the outer part of the housing 1 from the side of the intake pipe 3 are mounted two brackets 9, which are fixed trubor the water 10, designed to supply water under pressure into a specific cavity 7. Each pipe 10 serves one specific cavity 7, and the pipelines are installed symmetrically and provide two rotors at the same time. The pipeline 10 through pipe 11 is connected to a distribution device 12, which is connected through a pipe 13 to a pump 14. Tubes 11 have a bend that allows you to set the distribution unit 12 and the pump 14 above the intake pipe 3 without interrupting the main flow of water. The distribution unit 12 and the pump 14 can be installed above the water on a special platform.

The turbine operates as follows.

Water flows through the inlet pipe 3 into the housing 1. This flow of water is divided guide 8 into two streams and fills the cavity 7. The water column, the height of which is determined by the distance between the plates 6 and the level in the reservoir, the pressure plates 6 and causes the rotating rotor 5. In the lower part of the housing 1 is pouring water from the cavity 7 in the exhaust pipe 4.

To ensure a more rapid rotation of the rotor 5, the variation of torque of the rotors used the pump 14, the distribution unit 12 and the piping system. From the pump 14, the pressurized water enters the distribution device 12, which directs the flow of this is th water in the respective cavity 7. And it happens consistently. As the movement of the plate 6 from the inlet pipe 3 to the outlet 4, the volume of the cavity 7 is increased and this is compensated for by the creation of additional water pressure. The increase in water pressure in the cavity 7 contributes to the rapid movement of the plates 6 and rotors 5.

The proposed design of the turbine allows you to ensure its rapid acceleration, change torque and to increase its capacity and efficiency. All this is possible by creating additional pressure in the cavities of the plates using a pump, switchgear and piping systems. The manufacture of the rotors of the pipes greatly simplifies the technology reduces labor costs and increases the reliability of the structure.

Turbine, comprising a housing with end caps, inlet and outlet fittings are accommodated in the housing two rotor is made of a pipe having a longitudinal slice, plate and streamlined the guide, and the turbine is equipped with an additional system, including pump, switchgear and pipelines, ensuring that the water pressure in the subsequently formed cavities between the plates and the casing, and the casing of the turbine has two bracket from the intake port to support pipe, characterized in that the you tube rotors set that part of the pipe served as plates, and the other part of the rotor body.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.

EFFECT: wider functional capabilities of a power installation with orthogonal turbines.
