Anti-seismic power transmission tower

Abstract

The invention relates to the technical field of power transmission towers, in particular to an anti-seismic power transmission tower. The anti-seismic power transmission tower comprises a tower body,wherein movable bases are separately arranged at four corners of the bottom of the tower body; the movable bases comprise bottom frames, movable plates, first elastic pieces, electric tower mounting plates, first notch bolts, balls, baffles, second elastic pieces and second notch bolts; the movable plates are arranged in the bottom frames; grooves are formed in the tops of the movable plates; first notch bolt matching grooves are formed in the outsides of the grooves; and a circle of limiting cavities are formed in the periphery of the first notch bolt matching grooves, the first elastic pieces are uniformly formed in the grooves, and electric tower mounting plates are arranged at the tops of the first elastic pieces. The anti-seismic power transmission tower has novel design and high applicability, and can effectively reduce the stress on a rigid structure of the tower body during earthquake, reduce the risk of breakage and collapse of the power transmission tower during earthquake, and is suitable for further popularization and use.

Description

technical field [0001] The invention relates to the technical field of transmission towers, in particular to an anti-seismic transmission tower. Background technique [0002] Electric towers are trapezoidal or triangular tower-shaped buildings, usually 25-40 meters high, and are steel frame structures. High-voltage electric towers are an important way of power transmission in my country. A large number of high-voltage electric towers are used in the West-to-East Power Transmission Project. With the development of the economy, the stable development of the national electric power industry has a direct relationship with the economic development of our country. . According to the statistics of transmission line accidents in recent years, high-voltage power towers are prone to toppling after being subjected to external forces such as earthquakes and strong winds. Since high-voltage power towers are generally relatively high and heavy, it is not only easy to cause large-scale pow...

AI Technical Summary

Problems solved by technology

Although this setting can improve the anti-seismic effect of the tower to a certain extent, the tower will still shake violently along with the ground during an earthquake. This kind of shaking force cannot be diverged and will completely act on the rigid structure of the steel frame of the tower. It is easy to cause the transmission tower to be damaged, broken or even collapsed
