Rotary vortex-induced vibration inhibiting device for steel pipe member of transmission tower
The invention provides a rotary vortex-induced vibration inhibiting device for a steel pipe member of a transmission tower. The vortex-induced vibration inhibiting device mounted outside the steel pipe member comprises two rolling lantern rings and a current disturbing wire. The two rolling lantern rings are mounted on the steel pipe member, and the inner and outer surfaces of the rolling lanternrings can rotate relatively. The current disturbing wire is spirally connected between the two rolling lantern rings. The device based on a basic principle of changing aerodynamic configuration inhibits aeolian vibration of the steel pipe member, and is clear in principle and high in practicality.
本发明提供了一种旋转式输电铁塔钢管构件涡激振动抑制装置，所述涡激振动抑制装置安装在钢管构件外，包括：2个滚动套环和扰流线；所述2个滚动套环安装在所述钢管构件上，且所述滚动套环的内表面和外表面可以相对转动；所述扰流线呈螺旋线型连接在所述2个滚动套环之间。本发明装置基于改变气动外形的基本原理，抑制钢管构件的微风振动，原理清晰，实用性强。
