Novel bridge vortex-induced vibration suppression device replacing protective guard
The novel bridge vortex-induced vibration suppression device is characterized in that the novel bridge vortex-induced vibration suppression device comprises a plurality of suppression assemblies composed of protective railings and grids, the protective railings are longitudinally arranged on a bridge floor main beam, heightening grids are transversely arranged at the bottoms of the protective railings, and the grids are transversely arranged at the upper portions of the protective railings; the centers of the two ends of the grid and the heightening grid are movably connected with the protective barrier and can be turned over and opened around the joint. According to the utility model, the formation of vortex vibration is inhibited from the source, the grid can be completely opened at a dangerous wind speed, the wind drag coefficient is reduced, the main beam is prevented from being subjected to an overlarge wind drag load, and the opening height of the grid can be adjusted in a targeted manner by the intelligent grid according to the condition of the wind speed, so that the generation of eddy current of the whole bridge is better inhibited. The system is an important component ofan intelligent control system.
本发明公开了一种替代防护栏的新型桥梁涡激振动抑制装置，其特征在于：包括多个由防护栏杆、格栅组成的抑制组件，所述防护栏杆纵向设置于桥面主梁上，所述防护栏杆底部横向设置增高格栅，上部横向设置格栅，所述格栅与增高格栅两端的中央与防护栏杆活动连接，并能绕此连接处翻转打开；本实用从源头上抑制了涡振的形成，格栅在危险风速下可以全部打开，降低风阻系数，从而避免主梁受到过大的风拽荷载，智能格栅能够根据风速的情况，针对性的调整格栅打开的高度，从而更好的抑制整桥涡流的产生，是智能控制系统的重要组成部分。
