[0002] With the rapid development of China's economic society, the demand for electricity is becoming increasingly strong. The modern society's dependence on electric power energy is increasing day by day, and the requirements for the safety and reliability of the power grid are also getting higher and higher. Transmission towers are important supports for the power grid. Being in the natural environment, they are often attacked by severe meteorological disasters, causing irreversible damage to the pole tower structure and even collapse.

[0003] By reinforcing the main materials of the transmission line, the ability of the transmission line to resist disaster weather can be improved, and the safe operation level of the transmission line can be enhanced, which has very significant economic and social benefits.

[0004] Currently, the main method for reinforcing the main materials of transmission towers is single-member splicing, which has relatively high requirements for the disassembly and assembly of the node bolts, increasing the project cost. Summary of the Invention

[0009] (3) The secondary main material is arranged side by side with the main material, and the end of the secondary main material is connected to the reinforcement device.

[0010] Further, a plurality of convex blocks are arranged on the main material, and a plurality of reinforcement devices are correspondingly arranged on the secondary main material for the convex blocks.

[0011] Further, the convex block is a steel jacket.

[0012] Further, both the main material and the secondary main material are L-shaped support members, steel jackets are symmetrically arranged on both outer side surfaces of the main material, and reinforcement devices are correspondingly arranged on both outer side surfaces of the secondary main material for the steel jackets.

[0013] Furthermore, the reinforcement device includes an L-shaped reinforcement member fixed to the secondary main material. Two fixing blocks are vertically connected outward on both sides of the free end of the L-shaped reinforcement member, and a connection port is formed between the two fixing blocks.

[0014] Furthermore, end connection devices are respectively arranged between the ends of the reinforcement devices on the two outer side surfaces of the secondary main material. The end connection device has four connection surfaces, wherein two connection surfaces are respectively fixedly connected to the outer side walls of the L-shaped reinforcement members of the two reinforcement devices, and the other two connection surfaces form clamping grooves adapted to the two side surfaces of the main material with the fixing blocks of the reinforcement device. The two side surfaces of the main material are respectively clamped into the corresponding clamping grooves for fixation.

[0015] Furthermore, the steel jacket, the reinforcement device, and the end connection device are all fixed by bolts, and bolt holes corresponding to each other are provided on the steel jacket, the main material, the L-shaped reinforcement member, the secondary main material, and the end connection device.

[0019] (2) The reinforcement form is simple. Since the present invention adds a secondary main material spliced to the main material, it will not occupy too much external space. After the main material is reinforced, it maintains the original cross-sectional form, making the iron tower simple and tidy, and the appearance is equally beautiful.

[0020] (3) The eccentricity of the main material under stress is small. The present invention adopts adding a secondary main material equal in length to the main material on the main material. The positions of the fixing devices on the secondary main material correspond to the steel jackets on the main material one by one. After installation, the upper and lower ends of the secondary main material and the main material are flush with each other, reducing the eccentric stress of the main material and enhancing the stress stability.
