A kind of electric tower of the antidetonation with soft varying stress
Technical field
The present invention relates to electric power facility, especially a kind of electric tower of the antidetonation with soft varying stress.
Background technology
Electric tower is the conventional facility of power industry, and for the erection of power main, its main body is steelframe, on the whole with one
Fixed elasticity, can bear larger vertical weight load, lateral force can be also born in corner stringing, but due to the Electric wire support of electric tower
In top, its tip loads is larger, when the horizontal seismic shock by earthquake disaster, and tip loads can be with electric rocking for tower
Huge side force is formed, electric tower is toppled over.
Some patents propose a plan for electric tower antidetonation at present, but these schemes are often divided into two classes, and a class is in iron
Cushion is set at bottom of towe pin, to prevent steel tower from excessively rocking;Two classes are that extra force application mechanism pair is set in steel tower sidepiece
Steel tower carries out righting;In first kind scheme, due to magnitude can not it is anticipated that and stringing load on steel tower so that it is slow

It is different, and displacement can change with seismic wave size, if outside force application mechanism can not be adaptive to seismic wave, antidetonation effect
Fruit will be affected.
When earthquake, the steel tower based on rigid material easily collapses, and the same top load of trees is larger, is but difficult to incline
, this aspect is because the well developed root system of trees provides firm foundations, on the other hand also in that trunk has good
Flexible force transmission structure and elasticity, enable foundation to rectify inclined to acutely rock progress of the trees in seismic wave, possess trees good
Shock resistance.Such as electric tower anti-seismic structure copies the trees characteristic, should be able to lift the shock resistance of steel tower.
Because the main material of electric tower is steel, with certain elasticity, when being influenceed by seismic wave and deform upon, if its is each
The deformation or displacement at position can possess restorability not less than limit value, then housing structure because of material property, such as electric tower due to
Top carrier power main, can often rock because of wind-force factor, but only need tower body deformation to be limited without departing from deformation level, and tower body can be because
The strong biased spring of composition of tower shell material itself restores;Similarly, set such as on tower body and rectify inclined power source, can effectively lift the antidetonation of electric tower
Ability.
