Detailed Description
As shown in fig. 2 and 3, a novel tower leg diagonal member connecting structure is mainly used for connecting tower leg diagonal members of unequal-height leg power transmission towers. Due to the limitation of topography in a power system, iron towers with different lengths at the lower part can be used as supporting points of a power cable, namely power transmission iron towers with unequal-height legs. The unequal-height leg power transmission line is sequentially provided with a tower head 1, a tower body 2 and unequal-height tower legs 3 from top to bottom, wherein the tower body 2 is formed by fixedly connecting a plurality of main materials 6, a partition cross rod 7 and tower body inclined materials, and the partition cross rod 7 is arranged at the lower end of the tower body and is connected with the unequal-height tower legs 3.
The unequal height tower legs 3 comprise four unequal height legs 4 and eight tower leg inclined materials 5, the four unequal height legs 4 surround the unequal height leg tower legs 3 of a quadrangle, and are fixedly arranged below the tower body 2. The four unequal-height legs 4 are connected with the lower end of a main material 6 of the tower body 2 according to the terrain, one end of the tower leg inclined material 5 is fixedly connected with the lower end of the unequal-height leg 4, the other end of the tower leg inclined material is connected with a partition surface cross rod 7 of the tower body 2 through a node plate 8, and two tower leg inclined materials 5 are respectively connected on one node plate 8.
