Abstract

The invention makes it possible to increase the efficiency of a wind turbine. The wind flow falling on the Savonius rotor (PC) 4, mounted on the support mast 1, fixed in the support node 3 with the help of the tension 2, begins to unwind it. A PC 4 kinematically associated with a wind wheel (B) 5 using a multiplier 15 and a hydraulic clutch 16 transfers its torque to the shaft last. After exceeding the torque of the hydraulic coupling 16 of the starting moment B 5, made in the form of hollow cylinders 6 with end flanges 7 placed around the PC 4 on the vertical shafts 8 with trunnions fitted with support rollers 9 in contact with the ring guide 10, B 5 also begins rotate. At the same time air flows falling on the side surface of each cylinder 6, made in the form of elastic plates, partially overlapping each other with the formation of gaps oriented circumferentially in one direction, and provided with reflective blades fixed on the inner side of the plates and connected to the end flanges 7, spun them. The torque is transmitted through the lower trunnion of the vertical shafts 8 to the gearbox, which is kinematically connected with the support roller 9. Such a total inclusion in the work of all elements of the wind turbine makes it easier to start. In the steady state, the PC 4 continues to transmit all the torque generated by it to the B 5 shaft. 2 s. f-ly, 5 ill.

is mechanically connected with the support roller 9. The Savonius rotor 4 is kinematically connected with the help of a multiplier 15 and a hydraulic coupling 16 coaxially mounted on the supporting mast 1. In addition, the Savonius rotor 4, a wind wheel 5, a reduction gear 14 and a hydraulic coupling 16 are equipped with shafts 17-20, respectively .

Wind turbine works as follows.

The flow of wind falling on the rotor 4 Savonius begins to spin it. Shaft 17 transmits a twisting moment using a multiplier to hydraulic shaft 20 of hydraulic valve 16. An increasingly unwinding working fluid transfers kinetic energy to the hydraulic clutch housing 16. After the torque of hydraulic clutch 16 of the starting torque of the wind wheel 5, is exceeded, it also begins to rotate. At the same time, the air flows falling on the cylinders 6, passing through the gaps 12, transfer kinetic energy to the reflecting vanes 13. The cylinders 6 begin to rotate around their own axis. The torque is transmitted through the lower trunnions to the gears of the gearbox 14, the output shaft 19 of which is simultaneously the drive shaft of the support roller 9. As the rotation speed of the wind wheel 5 increases, the Magnus force also increases. The moment increasing from it is transmitted to the shafts 19 of the rollers 9, accelerating their rotation, which, in turn, facilitates | This increases the number of revolutions of the wind wheel 5. Thus, there is a uniformly accelerated exit to the nominal mode of operation of the wind turbine. In the steady state, the rotor 4 of Savonius continues to transfer all of the developed torque to the shaft 18, since the multiplier 15 on its output shaft has a greater number of revolutions compared to the nominal speed of rotation of the shaft 18 by the amount of working slip of the hydraulic clutch. Thus, on the shaft 18, the mechanical energy of the cylinders and the 4Savonius rotor rotating at different speeds is summed up, which makes it possible to increase the utilization rate of the wind.
