Abstract

The invention relates to disturbing flow devices, wind vortex devices with the disturbing flow devices and a perpendicular shaft wind power generator set. The disturbing flow devices are used for thewind vortex devices of the perpendicular shaft wind power generator set and spirally extend on the outer surfaces of blades of the wind vortex devices in the axial directions of the wind vortex devices. According to the disturbing flow devices, the wind vortex devices with the disturbing flow devices and the perpendicular shaft wind power generator set, by means of the manner that the disturbing flow devices are arranged on the outer surfaces of the blades, the wind vortex devices are made to reduce the vortex-induced vibration effect of the blades, and the anti-typhoon efficacy of the perpendicular shaft wind power generator set can also be enhanced at the same time.

Description

technical field [0001] The invention relates to the technical field of vibration suppression of vortex-induced vibration, in particular to a wind turbine and a vertical axis wind power generating set. Background technique [0002] In the field of wind power, ultra-large and ultra-large units will be the future development trend, and because the vertical axis wind turbine has a small transverse shear force on the tower column, the vertical axis wind turbine can generate electricity under the condition that the load of the tower column is allowed. Compared with the horizontal axis wind turbine, the wind rotor of the unit can be made higher and larger, thereby improving its power generation efficiency. [0003] The wind rotor includes a plurality of blades distributed around the rotating shaft, and the wind force drives the wind rotor to rotate around the rotating shaft to drive the generator to generate electricity. The blade will vibrate greatly under a certain wind speed, w...
