A movable anti-seismic transmission tower

Abstract

The invention relates to the technical field of power transmission towers, in particular to a movable anti-seismic power transmission tower which comprises a base tower, a middle tower and a top tower. First elastic parts are arranged at the bottom of the base tower, bottom plates are arranged at the bottoms of the first elastic parts, and a vibration sensor and a controller are arranged on the base tower. Square grooves are formed in the tops of the base tower and the middle tower, square inserting blocks are arranged at the bottoms of the middle tower and the top tower, the square insertingblocks are inserted into the square grooves, clamping grooves are formed in the square inserting blocks, limiting blocks are arranged in the clamping grooves, inserting grooves are formed in the middle of the limiting blocks, the limiting blocks are fixed at the bottoms of the square grooves, and electric hydraulic telescopic rods are arranged at the bottoms of the limiting blocks. The movable anti-seismic power transmission tower is novel in design and high in shock resistance; free shaking of the three-section type tower body can be achieved, the stress on rigid mechanisms of the tower bodyis reduced, the risks of breakage and collapse of the power transmission tower are reduced, and the power transmission tower is suitable for further popularization and use.

Description

technical field [0001] The invention relates to the technical field of transmission towers, in particular to a movable 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-sc...

Problems solved by technology

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 power interruptions, but also cause personal casualties , is extremely dangerous

[0003] For example, the patent number is CN201620697567.3 utility model patent, which discloses an anti-seismic transmission tower, which improves the anti-seismic capacity of the tower body through the stabilization of the anti-vibration rod, and prevents the tower body from twisting and breaking when it vibrates ; Although this kind of setting can improve the anti-seismic effect of the transmission tower to a certain extent; but the shaking force exerted on the rigid steel frame structure of the tower body during the earthquake still cannot be well diverged, so the rigidity of the tower body during the earthquake The steel frame structure is still prone to fracture, which in turn causes the collapse of the tower
