INVENTION
Patent of the Russian Federation RU2046993
HYDRO-ELECTRICAL INSTALLATION
The name of the inventor: Shkurikhin Igor Borisovich
The name of the patent holder: Shkurikhin Igor Borisovich
Address for correspondence:
Date of commencement of the patent: 1994.06.10
Use: to generate electricity by using the kinetic energy of rivers and streams. SUMMARY OF THE INVENTION: the blades 4 of the hydroturbines are made in the form of bodies of revolution, each of which is mounted on an autonomous shaft 5 provided with a drive mechanism.
DESCRIPTION OF THE INVENTION
The invention relates to hydropower and can be used to generate electricity by using the technical energy of rivers and watercourses.
The closest to the invention is a hydropower plant containing a hydroturbine with a rotor, blades and a shaft kinematically connected to the generator.
The disadvantage of such an installation is the use of only a small part of the kinetic energy of the flowing water, which leads to a reduction in the power of the installation.
The purpose of the invention is to increase the power of the installation.
The aim is achieved by the fact that the turbine blades are made in the form of bodies of revolution, each of which is mounted on an autonomous shaft equipped with a drive mechanism, and that the drive mechanism of the blade is in the form of a gear wheel, and on the turbine housing, coaxially with the rotor, A wheel engaging with the blade wheel and that at least one of the blades is provided with a starting motor kinematically connected to its shaft and a hydroturbine mounted on the rotor.

1 shows a hydroelectric unit; FIG. 2 shows a section AA in FIG. 1 and a flow pattern of blades. FIG.
The hydroelectric plant comprises a hydroturbine with a rotor 1, a shaft 2 of a rotor 1, a casing 3, blades 4 fixed to the shafts 5, a starting motor 6 mounted coaxially with the shaft 5 of the blade 4 and connected to it by means of a coupling 7, a multiplier 8 and a generator 9.
A gear 10 is mounted on the shaft of each blade, meshing with a fixed gear 11 fixed coaxially with the rotor 1 on the body 3. A fairing 12 is provided on the lower part of the rotor 12. The rotor 1 is provided with contact rings 13 for supplying an electric current to the starting Electric motor 6. The device body 3 is supported by the pawls 14 on the pontoon 15, which holds it on the surface of the water.
HYDRO-ELECTRICAL INSTALLATION WORKS AS FOLLOWING
When electric current is supplied to the starting electric motor 6 from an external power source (for example, from a battery), the gears 10, and with them the blades 4, are rotated, since they engage the fixed gear 11, the installation rotor 1 and Begins to rotate, so that it generates the torque transmitted to the generator 9. After the rotor 1 goes to the operating speed, the starting motor 6 is turned off. However, when the unit is operating, for example, with partial loads or loads exceeding the load of the main generator 9, the motor 6 can operate in the generator mode. In this case, the electric current produced by it through the contact rings 13 will be transmitted to the external network.
As a result of the fact that the direction of circulation in the flow around the blades 4, made in the form of bodies of rotation, is maintained regardless of their position, and the magnitude of the lifting force acting on them is approximately an order of magnitude greater than the lifting force acting on conventional wing profiles, Substantially increases.
