Adjustable wind vibration control device for steel pipe component of power transmission tower
The invention belongs to the field of power transmission line wind resistance design, and provides an adjustable power transmission tower steel pipe component wind vibration control device which is arranged outside a steel pipe component in a sleeving mode and comprises two lantern rings, and two spoilers are arranged between the two lantern rings in the axial direction of the steel pipe component. The lantern ring comprises two semicircular lantern rings, the two semicircular lantern rings are connected through lantern ring connecting bolts, a rotating shaft support is arranged on the peripheral face of each semicircular lantern ring, each rotating shaft support comprises a base and two cover plates, the bases are arranged on the semicircular lantern rings and connected with the cover plates through pin shafts, and the two cover plates are connected with the base through pin shafts. A space formed by the base and the cover plate is used for mounting the spoiler; during application, the two cover plates are opened, the windward angle of the spoiler is adjusted according to the vibration strength of a steel pipe component, and the two cover plates are locked through the cover plate connecting bolts after adjustment. The aerodynamic configuration of the component is changed by controlling the angle of the spoiler, and the purpose of restraining wind vibration of the rod piece is achieved.
本发明属于输电线路抗风设计领域，提供了一种可调节式输电塔钢管构件风振控制装置，所述风振控制装置套在钢管构件外，包括两个套环，在两个套环之间沿钢管构件轴向方向上设有两个扰流板；所述套环包括两个半圆形套环，所述两个半圆形套环通过套环连接螺栓连接，每个半圆形套环外周面上设有转轴支座，所述转轴支座包括底座和两个盖板，所述底座设置在半圆形套环上，所述底座与盖板通过销轴连接，其中，底座与盖板所形成的空间用于安装扰流板；在应用时，两个盖板开启，根据钢管构件振动强弱程度调整扰流板的迎风角度，调整后通过盖板连接螺栓将两个盖板锁紧。本发明通过控制扰流板的角度来改变构件的气动外形，达到抑制杆件风振的目的。
