The invention relates to a vortex-induced vibration suppression device for an omni-directional coated power transmission and transformation steel pipe component. The vortex-induced vibration suppression device comprises a hollow sleeve and a plurality of wing plates, the wing plates are strip-shaped plates and are evenly fixed to the outer surface of the sleeve in the axial direction of the sleeve, and the sleeve is connected to the steel pipe component in a sleeving mode. According to the vortex-induced vibration suppression device, air flow trajectory is effectively changed, the wing platescan disturb vortex-induced formation, the vortex-induced vibration of the steel pipe in a power transmission line is suppressed, and the suppression effect is optimal when the distance between the wing plates is 90 degrees.
本发明涉及一种全向裹覆输变电钢管构件涡激振动抑制装置，包括：中空的套筒和多块翼板，所述翼板为条形板，沿所述套筒的轴向均匀固定于所述套筒的外表面上，所述套筒套接于钢管构件上，本装置有效改变空气流动轨迹，并且翼板可以扰乱涡激的形成，抑制了输电线路中钢管的涡激振动，当翼板之间间距90°时，抑制效果最佳。
