Vortex-induced vibration suppression device of power transmission steel tube tower self-adjusting surrounding structure
The invention provides a vortex-induced vibration suppression device for a self-adjusting surrounding structure of a power transmission steel tube tower, and belongs to the technical field of vortex-induced vibration suppression of power transmission line steel tube towers. The problems that an existing power transmission steel pipe tower is high in vibration reduction cost, not high in applicability, not capable of achieving an ideal effect and limited in installation are solved. The self-adjusting surrounding pneumatic control structure comprises a plurality of self-adjusting surrounding pneumatic control structures arranged on a steel pipe structure in a sleeving mode, each self-adjusting surrounding pneumatic control structure comprises an annular lantern ring, two rigid supporting columns and two flow guide plates, the two rigid supporting columns are arranged on the periphery of each annular lantern ring, and the flow guide plates are correspondingly installed on the rigid supporting columns. The annular lantern ring can rotate around the steel pipe by 360 degrees, the annular lantern ring is balanced with wind power according to different wind attack angles, and the annular lantern ring is automatically adjusted to stay at different positions. The service life of the steel pipe can be effectively prolonged, the construction device is simple, manufacturing is easy, and high practical value is achieved.
本发明提出了一种输电钢管塔自调节环绕结构的涡激振动抑制装置，属于输电线路钢管塔涡激振动抑制技术领域。解决了现有输电钢管塔减振成本高、适用性不强，达不到理想效果、安装受限制的问题。它包括多个套在钢管结构上的自调节环绕气动控制结构，自调节环绕气动控制结构包括环向套环、两个刚性支撑柱和两个导流板，每个环向套环外周设置两个刚性支撑柱，每个刚性支撑柱上对应安装有导流板，环向套环能够绕着钢管360°转动，根据风攻角的不同，环向套环与风力平衡，自调节停留在不同的位置。本发明可有效提高钢管的使用寿命，构造装置简单，制作简单，具有很高的实用价值。
