Description

Technical Field

[0001] This utility model belongs to the field of steel pipe tower technology, and in particular relates to an intelligent control and protection device for wind vibration of steel pipe towers. Background Technology

[0002] Steel pipe towers, as important supporting structures for conductors and lightning protection wires in overhead transmission lines, are widely used in ultra-high voltage transmission line projects due to their high load-bearing capacity and structural stability. However, traditional steel pipe towers are prone to vortex-induced vibration and galloping under strong winds, and long-term vibration can lead to structural fatigue damage.

[0003] This continuous and repetitive vibration can cause accidents such as loose bolts on transmission towers, fatigue failure of poles, and cracking of connecting plates, posing a huge safety hazard to power grid operation. At present, some wind-induced vibration control methods have problems such as high cost and unsatisfactory results. For example, fixing the turbulence ribs to the outer wall of the clamp and then to the outer wall of the steel pipe requires longer clamps or multiple clamps if the steel pipe is long, which greatly increases the cost.

[0004] Therefore, it is essential to invent an intelligent control and protection device for wind-induced vibration of steel pipe towers. Utility Model Content

[0005] To comprehensively address the aforementioned problems, especially the shortcomings of existing technologies, this utility model provides an intelligent control and protection device for wind-induced vibration of steel pipe towers, thereby resolving the issues raised in the background section.
