Vortex vibration suppression device with adjustable ventilation rate
The invention discloses a vortex-induced vibration suppression device with an adjustable ventilation rate, and belongs to the technical field of bridge vortex-induced vibration suppression devices. The guardrail is composed of a plurality of guardrail units which are transversely arranged, each guardrail unit comprises a stacked I-shaped stand column, a plurality of sets of transverse ventilation units which are vertically arranged are arranged in the length direction of each I-shaped stand column, and each transverse ventilation unit comprises a through groove formed in the corresponding I-shaped stand column. Fixing ropes are arranged at the upper end and the lower end of each through groove, the two ends of each fixing rope are connected to the symmetrically-arranged I-shaped stand columns respectively, a plurality of sliding rings are arranged on each fixing rope, flexible cloth matched with the fixing ropes in length is arranged between the fixing ropes, and the two side faces, in the width direction, of the flexible cloth are fixed to the sliding rings; a reset spring is arranged between every two adjacent sliding rings, and mounting plates are arranged on the lower portions of the through grooves between the ends of the fixing ropes. The technical scheme is used for actively inhibiting the vortex vibration effect in various wind environments.
本发明公开了一种透风率可调节的涡振抑振装置，属于桥梁涡振抑制装置技术领域。由若干个横向排列设置的护栏单元组成，单个所述护栏单元包括堆成设置的工字型立柱，所述工字型立柱长度方向上设有若干组竖向排列的横向透风单元，单个所述横向透风单元包括设置于工字型立柱上的通槽，所述通槽的上端和下端均设有固定绳，所述固定绳的两端分别连接于对称设置的工字型立柱上，所述固定绳上均设有若干滑环，所述固定绳之间设有与其长度匹配的柔性布，所述柔性布宽度方向上的两侧面固定于滑环上，相邻滑环之间均设有复位弹簧，所述固定绳端部之间的通槽下部均设有安装板。本技术方案用以主动抑制多种风环境下涡振效应的发生。
