The water turbine is designed for use in a low-power hydroelectric plant. The turbine contains a body with end caps, inlet and outlet nozzles. In the case there are two rotors and a streamlined guide. The rotors are made of pipes having a longitudinal section and installed so that part of the tube serves as a plate and the other as a rotor housing. Water turbine and is equipped with a system that includes a pump, switchgear and pipelines that ensure the creation of water pressure in the successively formed cavities between the plates and the body. The design of the turbine makes it possible to reduce labor costs for its production.
DESCRIPTION OF THE INVENTION
The invention relates to hydraulic machines with movable flaps using a liquid flow and can be used as a hydraulic turbine of a low-power hydroelectric power plant.
A hydroturbine is known, comprising a housing with end caps, inlet and outlet nozzles, a rotor with movable plates, one end of which is hinged to the rotor, and a streamlined guide (Patent No. 2147078, MKI F 03 B 17/06).
However, in this construction of a hydroturbine, where two rotors are used in one unit, its capabilities are not fully realized. So when water flows through the turbine (pressure constant), you can not use full power and provide the maximum efficiency. The change in torque in a hydroturbine depends only on the pressure of the flowing water.
A hydraulic turbine is known, containing a body with end caps, inlet and outlet nozzles, two rotors and a streamlined guide placed in the body (Patent No. 2191919, MK F 03 B 17/06 - prototype).
However, this turbine has movable plates that are fixed on one side hinged on the rotor, on the other - by means of pins installed in the slots of the body. The manufacture of such a construction of plates requires great accuracy and labor, in general, the design of the hydroturbine is complex.
The invention is aimed at solving the problem of simplifying the design of a hydroturbine, reducing labor costs for its production.
This is achieved by the fact that the rotors are made of pipes having a longitudinal section and installed so that a part of the tube serves as a plate and the other part as a rotor housing, it is equipped with an additional system comprising a pump, a distributor and pipelines that create a water pressure in Successively formed cavities between the plates and the body, and on the body of the turbine there are two brackets on the side of the inlet pipe for fixing the pipelines.
The invention is illustrated in the drawing, which shows a general view of a hydroturbine in a section.

The hydraulic turbine includes a housing 1 with end caps 2 (only the back cover is visible in the figure), inlet 3 and outlet 4 nozzles located in the housing 1 of the rotors 5. The rotors 5 are made of tubes having a longitudinal section and are installed so that the inner part of the pipe performs The role of the plate 6, and the other outer part - the rotor housing. Between the plates 6 and the body 1, water-filled cavities 7 are formed, and a streamlined guide 8 is provided between the rotors 5. On the outer part of the body 1, on the side of the inlet pipe 3, two brackets 9 are mounted in which the conduits 10 are fixed for supplying pressurized water to a certain cavity 7. Each conduit 10 serves one specific cavity 7, the pipelines being installed symmetrically and providing the operation of the two rotors At the same time. The pipelines 10 are connected to a distributor 12 via a pipe 11 which is connected by a single pipe 13 to the pump 14. The pipes 11 have a bend that allows the distributor 12 and the pump 14 to be installed above the inlet pipe 3 without interfering with the main flow of water. The switchgear 12 and the pump 14 can be installed above the water in a special area. |
HYDROTURBINE WORKS AS FOLLOWS:
The flow of water flows through the inlet pipe 3 into the body 1. This water flow is divided by the guide 8 into two flows and fills the cavities 7. A column of water whose height is determined by the distance between the plates 6 and the level in the reservoir presses the plates 6 and causes the rotors 5 to rotate. In the lower part of the body 1, water is poured from the cavities 7 into the outlet 4.
To ensure faster rotation of the rotors 5, changes in the rotor torque are utilized by the pump 14, the switchgear 12 and the piping system. From the pump 14, pressurized water enters the dispenser 12, which directs the flows of this water to the respective cavities 7. This occurs in series. As the plate 6 moves from the inlet 3 to the outlet 4, the volume of the cavity 7 increases and this is compensated for by creating an additional water pressure. Increasing the water pressure in the cavity 7 facilitates the rapid movement of the plates 6 and the rotors 5.
The proposed design of the hydroturbine makes it possible to ensure its rapid acceleration, to change the torque and to increase its power and efficiency. All this is possible by creating additional pressure in the cavities of the plates by means of a pump, a switchgear and a piping system. The manufacture of rotors from pipes greatly simplifies the technology, reduces labor costs and increases the reliability of the design.
