To consume vibrational energy, or by applying energy act on influence to structure to offset external load.Specifically structure certain
Certain device, mechanism or minor structure are installed in a little positions, so that the dynamic characteristics of structure or dynamic action is altered or modified, structure is existed
Dynamic response under external load effect is rationally controlled.Therefore, it may be considered that power consumption is set up on overhead power transmission tower structure
Device to it carries out wind dynamic control.
Metallic yield damper long-term use of function it is constant and reduce maintenance expense in terms of have it is very prominent the characteristics of, by
The advantages that annular energy consumer Maintenance free that metal damper is formed, has good endurance, and service life is long.Therefore, can be with
It is arranged on annular energy consumer as damper device on cruciform shape overhead power transmission tower structure, wind shake control is carried out to it
System.
The content of the invention

Under be sequentially provided with multigroup cruciform shape diagonal brace, every group of cruciform shape diagonal brace is intersected by two hounds 1 to be formed, hound
Upper and lower side is connected in the two root posts 2 of the shaft tower ipsilateral, it is characterized in that：Looked for by structural analysis and field measurement
On the shaft tower side of the architectural characteristic weak part gone out, by the Delta Region that is formed between hound 1 and column 2, provided with straight
Footpath is 70% annular energy consumer of the Delta Region inscribed circle, and the Behavior of Circular Ring Energy Dissipator is connected to by supporting bar 3
The cusp position of the hound 1 and column 2 and the inscribed circle.
Connected between described Behavior of Circular Ring Energy Dissipator 4 and supporting bar 3 by connection component, connection component is overlapping fitting
2 band steels, it is bent outwardly to form hole respectively among two band steels, described hole coordinates the rod member of the Behavior of Circular Ring Energy Dissipator annulus straight
Footpath, two band steel both ends are all provided with bolt connection through hole, respectively locking Behavior of Circular Ring Energy Dissipator annulus and connection support bar part 3.
Described supporting bar 3 is Q235 steel band steels.
Described Behavior of Circular Ring Energy Dissipator refers to common Behavior of Circular Ring Energy Dissipator, bicyclic ringmild steel energy dissipator or Behavior of Circular Ring Energy Dissipator of putting more energy into.
Described tower structure characteristic weak part can be found out by the structural analysis and field measurement of prior art.
So Behavior of Circular Ring Energy Dissipator is integrally formed with cruciform shape overhead power transmission shaft tower, and overhead power transmission shaft tower integral rigidity carries
It is high.
Due to using such scheme, the beneficial effects of the invention are as follows：
1) this shaft tower can improve the integral rigidity of structure and local bearing capacity.
2) Behavior of Circular Ring Energy Dissipator deforms under typhoon load action, dissipation part energy, and then improves overhead power transmission
The overall performance of shaft tower.
3) this tower structure is simple, and designability is strong, employs metal power consumption mechanism, simple structure, simple processing, uses
It is convenient.
4) occupy little space, cost is low.
