Steel tube tower for preventing breeze vibration

Abstract

The invention discloses a steel tube tower for preventing breeze vibration. The steel tube tower comprises a steel tube tower body and various rod pieces, and is characterized in that irregular spoilers are arranged on the rod pieces and used for disturbing vortexes formed after breeze bypasses the rod pieces, and the irregular spoilers are arranged on the rod pieces of the steel tube tower. The shape, the number and the size of the spoilers are adjusted according to the wind speed and the property of a wind field to disturb or prevent the vortexes formed after transverse wind bypasses a steelpipe, so that gentle breeze vibration of the rod pieces is prevented, the steel tube tower is subjected to test application in a Xilin Gol League-Shengli 1000-kilovolt power transmission line projectfor the first time, and a satisfactory result is obtained. Compared with traditional guy wires and other treatment measures, the steel tube tower is more convenient to construct and more obvious in effect, breeze vibration is prevented from happening fundamentally, the steel tube tower can be used in being-built and built projects on a large scale, and especially for solving breeze vibration of asteel pipe tower structure which is put into operation, the steel tube tower is more convenient and faster to construct and remarkable in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, in particular to a steel pipe tower for preventing breeze vibration. Background technique [0002] The steel pipe tower structure is adopted for the double-circuit iron tower or the large-span (crossing the river) iron tower of the UHV transmission line project. However, some of the rods with relatively large slenderness (more than 110), including cross members at the lower part of the tower body, horizontal partition members, and V-surface members at the legs, are prone to lateral vibration perpendicular to the wind direction when the wind speed is small. It is called breeze vibration. This continuous and repeated breeze vibration will cause the bolt connection of the rod to loosen or the fatigue damage of the connecting plate, which will lead to potential safety hazards in the structure and reduce the service life.
