Description

Description of the invention

The subject of the invention is a high-efficiency hydro-unit immersed in water included in a water supply system that uses the energy of the water level difference as a result of water flow through the hydro-unit, converting the kinetic energy of water into mechanical energy in the turbine, and then the mechanical energy transferred to the generator shaft will be converted into electricity. The water flowing in the water pipe, after losing its kinetic energy, flows out of the water pipe into the river.

In the current state of technology, solutions are known and exploited in which water turbines work independently, transferring the mechanical energy of the turbine to working devices such as water mills or water sawmills.

There are also known solutions for transferring mechanical energy to a power generator only through toothed or belt transmissions. Due to technical requirements, to maintain a constant rotational speed of the generator, gears are used to increase or decrease the rotational speed between the turbine and the generator.

Known solutions require a complicated development of devices to protect against the outflow of oils, greases or other components that pose an ecological threat to the environment in which they work. The above requirements limit the use of hydro-unit solutions due to the construction and operating costs.

The presented shortcomings have been eliminated in the solution according to the invention, in which the generator rotor with magnets is coupled through a bearing assembly with the turbine rotor with angularly adjustable tilting blades, and on the outer side of the generator there is a casing with a stub pipe and a water flow slot for cooling the generator, which on the side of the generator is is closed with a wrap covering the hydraulic cylinder controlling the angular position of the blades.

In the solution according to the invention, a particularly advantageous and unobvious effect of the possibility of building small-size generators without the need to cool them with ambient air with a fan was obtained, because its use reduces the efficiency of the generator by about 1%. An important advantage is also the construction of the generator containing a rotor with permanent magnets, which does not consume electricity for magnetizing the rotor.

The invention is shown in an embodiment in the drawing showing a longitudinal section through the hydro-unit.

As shown in the figure, in the construction of the generator, the windings 2 are cooled by water supplied by the water jacket 9 to deflection the tilting blades 6 of the turbine rotor 5. The combined action of the generator rotor of the winding 2 with the magnets permanently results in a lower operating temperature. From the outside of the winding generator 2 there is a housing with an inspection port 1 and a water jacket 9 for the flow of cooling water to the winding 2 generator, which is closed with a wrap 4 on the upstream side.

The connection of the bearing assembly 8 of the turbine rotor 5 mounted on a common shaft with the winding generator 2 creates a hydro-unit, obtaining conditions for use in clutch assembly operations. In addition, it is very important that the hydro-unit does not need to be equipped with gears that change the rotational speed of the winding generator 2 in relation to the turbine rotor 5. The bearing unit 8 on both sides is equipped with face seals 7 separating the lubricating media of the bearing unit 8 from the side of the flowing water, i.e. the turbine rotor 5 and the rotor shaft 3 of the winding generator 2, closed by the angular position of the tilting blades 6.
