Device and method for suppressing swing of ultrahigh fan tower barrel

The invention relates to the technical field of wind power construction, in particular to a device and a method for suppressing swing of an ultrahigh fan tower barrel. The device comprises a tower barrel and turbulence strips, wherein the turbulence strips are wound on the top section of the tower barrel in a spiral convex structure. According to the method, the spiral convex structure is arrangedon the top section of the tower barrel, so that the flow of wind that affects the surface of the tower barrel is disrupted, and vortex generation is suppressed. The present invention arranges turbulence strips at the top end of the tower barrel to reduce the amplitude of vibration and to disrupt the flow of wind that affects the surface of the tower, so that vortex generation is suppressed, the wake field behind the components can be changed, and the regular venting of vortex of the wake field can be broken. The amplitude of the top end of the original tower barrel after arranging the turbulence strips can be reduced
