Starting date of the patent: 2000.04.20
The invention relates to the field of wind energy. The technical result consists in increasing the capacity of the wind farm and running it under a load provided by the fact that in the process of increasing the power and start the wind power plant by suction of air flow into the hollow propeller blades through a central diffuser, the air compression by the centrifugal force and discharged to the outside through nozzle according to the invention the air is sucked through the protective grid and controlled solenoid valve incorporated in the diffuser structure, which in normal operation of the wind farm is opened, allowing air to the jet nozzles pass, wherein a portion of the compressed air is injected through integrated blade tube and through the control valve in the compressed container gas, after which the filling control valve is closed, the start station is carried out by closing the valve of the diffuser and the compressed air is directed to run in the same jet nozzles arranged tangentially, and the control valve is opened. This method is implemented in the respective wind farm.
DESCRIPTION OF THE INVENTION
The invention relates to the field of energy, namely, to wind power.
Known method of increasing the power of wind power Copyright certificate USSR 55 996 (1), where the impact on the air flow through its compression by the centrifugal force at the ends of the hollow propeller blades during rotation, wherein the incoming air stream is fed into the blade through a central diffuser and discharged outside.
The disadvantage of this and other (2) of wind farms is their inability to run under load.
The closest prior art to be considered Russian Patent 2136958 (3) offering a wind power generating device comprising a propeller with hollow blades, the front central diffuser and a power generator in which a method of increasing the power and launch the wind farm is carried out by the suction of air flow inside the hollow blades of the propeller through a central diffuser air compression by the centrifugal force and discharged to the outside through the nozzles.
Object of the invention is implemented by receiving and storing compressed air secondary pneumatic power to run the wind farm, and using the same exhaust jet nozzles arranged tangentially at the blade tips.
The invention is illustrated by a drawing.

Wind power plant consists of three four-bladed propeller hollow one, at the ends of which a tangentially arranged nozzle 2. The center of the diffuser an adjustable propeller 4 with a safety net 3, which is placed inside the coil of an electromagnet controlling the inlet valve 5, which provides a full-time work in the open position, and closed - launch stations. During normal operation the valve 5 is opened by spring 6. Inside each blade sampling tube 7 housed portion of the compressed air from the ends of the blades through the control valve 8 in the compressed air tank 9 to run. On the container fitted with a pressure sensor 10, indicating that the station is ready for launch. All these control station units are enclosed in a conical cowl 11 which together with the propeller rotating part 1 forms a wind power plant connected to the shaft 13 of the electric generator. |
On the bottom of the housing 14 is a current collector 12 that supplies voltage to the coil of an electromagnet placed inside the diffuser 4, the control valve 8 and a control signal output from the pressure sensor 10.
Generator 13 is mounted in a conical fairing 14 having the ability to rotate around the axis of the support 15 by the control motor 16 and the rack 17.
At the apex of the cone of the fairing is installed a flashing red light safety 18.
Wind power plant works as follows
The incoming flow of air through the protective grid 3 and through the open solenoid controlled valve 5 and the diffuser 4 is sucked into the cavity in the propeller jet nozzles 2. Under the action of centrifugal force to increase the air pressure end of the blade and release it via a tangentially disposed outwardly jet nozzle 2 and provide additional strength for rotating the propeller. Part of compressed air is injected through integrated blade tube 7 and the control valve 8, the compressed gas tank 9 for launching station, which is carried out by closing the diffuser valve 5, and the compressed air is directed in the same tangential jet nozzle 2 and the air discharge valve 8 in tank 9 is opened.
Torque rotation of the propeller 1 and the conical fairing is transmitted to the shaft of the electric generator 13, generating an electric current.
Electric units control circuit of the rotating unit via the current collector 12 linked by cable to an automatic wind farm.
Running wind farms is performed as follows: by means of the coil 3, located inside the diffuser 4, closing the valve 5, and then open the valve 8, whereby the recirculation air become closed cavity propeller and release it through the same working nozzle 2 is mounted tangentially on the ends blades, and create a reactive force to scroll through the propeller load.
For a given direction of the wind farm on the air flow turning it relative to the support shaft 15 by the motor 16 and the rack 17.

CLAIM
1. A method for increasing the power of wind power and run by suction of air flow inside the hollow propeller blades through a central diffuser, the air compression by the centrifugal force and discharged to the outside through the nozzle, characterized in that air is sucked through the protective grid and controlled solenoid valve, integrated into the structure diffuser, which in normal operation of the wind farm is opened, allowing air to the jet nozzles pass, wherein a portion of the compressed air is injected through integrated blade tube and through a control valve to a pressurized gas container after filling which the control valve is closed, the start station is carried out by closing the diffuser valve, and compressed air is fed to run in the same jet nozzles arranged tangentially, and the control valve is opened.
2. Wind power plant, consisting of a hollow propeller blade, a central inlet diffuser and an electric current generator, characterized in that the ends of hollow blades mounted jet nozzle and the inlet diffuser has a protective grid, wherein the diffuser is located inside the coil of an electromagnetic valve which in an open state is able to provide a full-time work, and in the closed position - starting station, inside each blade has sampling tube portion of the compressed air from the ends of the blades that are able to direct it through the control valve in the compressed air tank to run, on which the pressure sensor having the opportunity to indicate that the station is ready to be launched, with all the control units of the station and launch container placed in a single rotating structure associated with the shaft generator.
