Crisscross overhead power transmission tower
The invention provides a crisscross overhead power transmission tower, which comprises four upright posts 2, wherein the four upright posts 2 form corner posts; a plurality of groups of crisscross inclined supporters are vertically and sequentially arranged on the side surface of a tower; each group of crisscross inclined supporters is formed by crossing two inclined support rods 1; and the upper end and the lower end of each inclined support rod are connected onto the two upright posts 2 arranged at the same side surface of the tower. The crisscross overhead power transmission tower is characterized in that annular energy dissipation devicesarearranged in triangular regions, formed between the inclined support rods 1 and the upright posts 2, on the side surface of the tower in a position with the weak structure characteristics found out through structure analysis and field measurement; the diameters of the annular energy dissipation devicesare70 percent of internally tangent circles in the triangular regions; and the annular energy dissipation devicesareconnected in positions of the tangent points of the internally tangent circles, the upright posts 2 and the inclined support rods 1 through support rod elements 3. The crisscross overhead power transmission tower has the advantages that the integral rigidity and the local bearing force of the structure of the overhead power transmission tower can be improved; a part of energy can be dissipated under the effect of a typhoon load; and further, the integral performance of the overhead power transmission tower is improved.
