Description

Modular connection node structure of assembled high-voltage transmission tower Technical Field The utility model relates to the technical field of high-voltage transmission towers, in particular to a modular connection node structure of an assembled high-voltage transmission tower. Background The high-voltage transmission tower ‌ is a power facility specially used for supporting transmission wires, lightning conductors and related accessories, plays a vital role in a power line, has a main function of ensuring efficient and safe electric energy transmission, and needs to fixedly assemble each connecting node in the process of constructing an assembled transmission tower. Through retrieving, the bulletin number is CN215889537U, the name is a transmission tower double-limb connection angle steel node structure, including angle steel main material, angle steel oblique material, one side of angle steel main material is provided with the gusset, and at least a portion of gusset is parallel with an angle limb of angle steel main material, through research analysis discovery, though when adopting same angle steel material and angle steel length, the node department bearing capacity that the double-limb connection was connected than the single limb is improved by a wide margin, and be closer to the axle center atress than the single limb connection, therefore the compressive capacity and the stability reinforcing of oblique material, nevertheless still have following defect to a certain extent. If the diagonal direction of the tower can not be supported and reinforced, the power transmission tower connecting node structure can only support and reinforce two adjacent sides of the tower after the assembly is completed, but the diagonal oblique direction can not be reinforced, so that the support force of the tower in the diagonal direction is poor, severe shaking easily occurs in severe weather such as strong wind, the whole tower is not firm enough, the length of the diagonal reinforcing plate can not be adjusted, the practicability is poor, flexible adjustment can not be performed according to towers with different sizes, and in order to solve the technical problems, the modular connecting node structure of the assembled high-voltage power transmission tower is designed.
