Overhead power transmission tower with high integral wind-resistant performance
The invention provides an overhead power transmission tower with high integral wind-resistant performance. The cross section of the overhead power transmission tower is a square frame defined by four vertical corner rods 1 and four horizontal side rods 2. A ball-shaped space energy dissipater is arranged in the middle of the square frame of the cross section of a weak part of the overhead power transmission tower through the field measurement and the structure analysis in the prior art. The ball-shaped space energy dissipater is formed by vertically intercrossing two circular rings 6; each circular ring 6 is formed by rolling a vertical low-carbon steel plate; four small-sized connecting plates (7) are symmetrically arranged at the crossing part of the horizontal plane where a ball center of the ball-shaped space energy dissipater is located and the circular rings; and the connecting plates (7) are supported on four corners of the square frame of the cross section of the overhead power transmission tower through support rods (3). The damage risk of the overhead power transmission tower is reduced through improving the integral wind-resistant performance of the overhead power transmission tower in two aspects including comprehensive improvement of the integral rigidity of the overhead power transmission tower and generation of the displacement for vibration reduction and energy dissipation. The overhead power transmission tower has the characteristics that the design is simple and convenient, the steel consumption is low, and the like. The overhead power transmission tower can be widely used in the wind-resistant reinforcement transformation of an overhead power transmission tower structure.
