Fence with adjustable ventilation rate
The invention relates to the technical field of bridge engineering, and provides a fence capable of adjusting the ventilation rate. The lifting base is arranged on the bridge, and the handrail is arranged on the lifting base; the fence capable of adjusting the ventilation rate further comprises an anemograph. The lifting base comprises a base body; the lifting section is rotationally arranged on the base body, the lifting section is used for stretching out and drawing back in the vertical direction, and a ventilation device is arranged on the lifting section; and the lifting section is rotated or/and stretched according to the wind speed detected by the anemograph, so that the lifting section reaches a preset rotating angle or/and a preset height, and the ventilation rate of the fence is changed. The lifting fence has the beneficial effects that the ventilation rate of the whole lifting base is improved by controlling rotation or/and stretching of the lifting joints, so that the whole fence can adapt to multi-order vortex vibration, and generation of large-amplitude vortex vibration is effectively restrained in different wind speed locking areas.
本发明设计桥梁工程技术领域,提供一种可调节透风率的围挡,该可调节透风率的围挡包括:栏杆;升降基座,升降基座设置在桥梁上,栏杆设置在升降基座上;其中,可调节透风率的围挡还包括:风速仪;升降基座包括:基座体;升降节,升降节转动设置在基座体上,且升降节用于沿上下方向伸缩,升降节上设置有透风装置;根据风速仪所检测的风速而旋转或/和伸缩升降节,以使升降节达到预设转角或/和预设高度,从而改变围挡的透风率。本发明的有益之处在于,通过控制升降节的旋转或/和伸缩来改善整个升降基座的透风率,使得整个围挡能够适应多阶涡振,在不同锁定风速区内有效地抑制大振幅涡振的产生。
