An anti-seismic electric tower with flexible stress

Abstract

The invention discloses an anti-seismic electric tower with flexible varying stress and a method thereof. The anti-seismic electric tower comprises a tower body, slant correction points and a slant correction force source. A main load-carrying structure of the tower body is provided with the multiple slant correction points at different heights and in different directions. The slant correction force source comprises a slant correction pile, slant correction pulley sets, an elastic force transferring mechanism, a counter weight member and an elastic base. The slant correction pile is vertically arranged on the ground of a hollow part of the tower center of the anti-seismic electric tower and is provided with the multiple slant correction pulley sets corresponding to the slant correction points. One end of a cable of each slant correction pulley set is hinged to the corresponding slant correction point on the tower body, and the other end of the cable is hinged to the elastic force transferring mechanism. The elastic force transferring mechanism comprises a force transferring end and a force applying end. The force transferring end is hinged to the cables of slant correction pulley sets, and the counter weight member is hung on the force applying end. The lower end of the counter weight member makes contact with the elastic base. The anti-seismic electric tower is provided with the slant correction force source and a special force transferring structure, and different flexible varying slant correction stresses can be provided for the key force bearing points of the electric tower structure according to the earthquake magnitude so as to stabilize the tower body.

Description

technical field [0001] The invention relates to power facilities, in particular to an anti-seismic electric tower with flexible stress. Background technique [0002] The electric tower is a common facility in the electric power industry. It is used for the erection of main transmission lines. The wires of the electric tower are mounted on the top, and the top load is relatively large. When the shock wave is impacted by the earthquake damage, the top load will form a huge lateral force with the shaking of the tower, causing the tower to fall. [0003] At present, some patents have proposed schemes for anti-seismic towers, but these schemes are often divided into two categories, one is to set a cushion layer at the foot of the tower to prevent the tower from shaking excessively; the other is to set additional construction on the side of the tower. In the first type of scheme, due to the unpredictable magnitude of the earthquake and the wire load on the iron tower, the effect ...

Problems solved by technology

[0003] At present, some patents have proposed schemes for anti-seismic towers, but these schemes are often divided into two categories, one is to set a cushion layer at the foot of the tower to prevent the tower from shaking excessively; the other is to set additional construction on the side of the tower. In the first type of scheme, due to the unpredictable magnitude of the earthquake and the wire load on the iron tower, the effect of the buffer cushion scheme is difficult to predict, while in the second type of scheme, due to the relatively large power tower High, the displacement of each part in the shock wave is different, and the displacement will change with the size of the shock wave. If the external force-applying mechanism cannot adapt to the shock wave, the seismic effect will be affected
