Abstract
The invention discloses a kind of herringbone column's substation framework steel pipe lightning rod for mitigating wind-induced vibration, including herringbone column, herringbone top end is installed with pedestal, ring flange has been bolted above pedestal, ring flange is provided centrally with lightning-arrest needle tube body, and lightning-arrest needle tube body is evenly distributed with several ribs in bottom cylindrical week；The surface of lightning-arrest needle tube body is provided with spiral guiding plate.The device in lightning-arrest needle tube body by being uniformly arranged ribs in bottom cylindrical week, so as to be effectively increased the rigidity of body and ring flange connecting node region, reduces node area destruction caused by wind shake effect；By being internally provided with right-angled intersection ribbed stiffener in lightning-arrest needle tube body, so as to increase the rigidity of body in itself, reduce the wind-induced vibration of body in itself；By being provided with spiral guiding plate on the surface of lightning-arrest needle tube body, so as to upset the track of incoming wind, prevent it from the stable whirlpool of forming frequency, and then effectively suppress the vortex-induced vibration of lightning-arrest needle tube body.
Description
Technical field
The present invention relates to lightning rod technical field, more particularly to a kind of herringbone column's substation framework steel pipe for mitigating wind-induced vibration
Lightning rod.
Background technology
Substation framework generally uses steel pipe inverted Y-shaped column structure outside domestic 500kV, 330kV, 220kV and 110kV room, and top
The lightning rod of setting is all the structural shape using single steel pipe, such a structural shape, in the presence of strong wind, is held at the top of lightning rod
Easily there is larger swing, in the presence of long-term, easily there is fatigue phenomenon in the steel pipe of lightning rod and the bolt of connection, weld seam etc.,
Ultimately result in the intensity decreases of lightning rod and broken ring.
The content of the invention
It is an object of the invention to provide a kind of herringbone column's substation framework steel pipe lightning rod for mitigating wind-induced vibration, to solve
The problem of being proposed in above-mentioned background technology.
The invention provides a kind of herringbone column's substation framework steel pipe lightning rod for mitigating wind-induced vibration, including herringbone column, institute
State herringbone top end and be installed with pedestal, ring flange, the center of the ring flange have been bolted above the pedestal
Lightning-arrest needle tube body is provided with, is evenly distributed with several ribs in the bottom cylindrical week of the lightning-arrest needle tube body；The lightning rod
Body is internally provided with right-angled intersection ribbed stiffener；The surface of the lightning-arrest needle tube body is provided with spiral guiding plate.
It is preferred that the lightning-arrest needle tube body is made up of steel pipe.
It is preferred that the spiral shell of the spiral guiding plate a height of 0.1D-0.25D, D are the diameter of steel tube of lightning-arrest needle tube body.
It is preferred that the pitch of the spiral guiding plate is 5D.
It is preferred that the herringbone column is made up of steel pipe, and cross ribbed stiffener is provided with the steel pipe.
Compared to the prior art the present invention, the advantage is that：
A kind of herringbone column's substation framework steel pipe lightning rod for mitigating wind-induced vibration provided by the invention, by lightning-arrest needle tubing
The bottom cylindrical week of body is uniformly arranged ribs, so as to be effectively increased the rigidity of body and ring flange connecting node region,
Node area caused by reducing wind shake effect destroys；By being internally provided with right-angled intersection ribbed stiffener in lightning-arrest needle tube body, so as to
The rigidity of body in itself can be increased, reduce the wind-induced vibration of body in itself.Rib thickness of putting more energy into is equal with pipe thickness；By
The surface of lightning-arrest needle tube body is provided with spiral guiding plate, so as to upset the track of incoming wind, prevents it from forming frequency
Stable whirlpool, and then effectively suppress the vortex-induced vibration of lightning-arrest needle tube body.

Embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection domain do not limited by embodiment.
As Figure 1-4, the embodiments of the invention provide a kind of herringbone column's substation framework steel pipe for mitigating wind-induced vibration to keep away
Thunder pin, including herringbone column 1, the top of herringbone column 1 are installed with pedestal 2, and the top of pedestal 2 is connected with by bolt 4
Ring flange, the ring flange are provided centrally with lightning-arrest needle tube body 5, and the lightning-arrest needle tube body 5 is uniformly distributed in bottom cylindrical week
There are several ribs 3；The lightning-arrest needle tube body 5 is internally provided with right-angled intersection ribbed stiffener 6；The lightning-arrest needle tube body 5
Surface is provided with spiral guiding plate 7.
Further, the lightning-arrest needle tube body 5 is made up of steel pipe.
Further, the spiral shell a height of 0.1D-0.25D, D of the spiral guiding plate 7 are that the steel pipe of lightning-arrest needle tube body 5 is straight
Footpath.
Further, the pitch of the spiral guiding plate 7 is 5D.
Further, the herringbone column 1 is made up of steel pipe, and is provided with cross ribbed stiffener in the steel pipe.
In summary, a kind of herringbone column's substation framework steel pipe for mitigating wind-induced vibration provided in an embodiment of the present invention is taken shelter from the thunder
Pin, by being uniformly arranged ribs in bottom cylindrical week in lightning-arrest needle tube body, connect so as to be effectively increased body with ring flange
The rigidity of node region is connect, reduces node area destruction caused by wind shake effect；By being internally provided with ten in lightning-arrest needle tube body
Word intersects ribbed stiffener, so as to increase the rigidity of body in itself, reduces the wind-induced vibration of body in itself.Rib thickness put more energy into managing
Wall thickness is equal；By being provided with spiral guiding plate on the surface of lightning-arrest needle tube body, so as to upset the track of incoming wind,
Prevent it from the stable whirlpool of forming frequency, and then effectively suppress the vortex-induced vibration of lightning-arrest needle tube body.
Disclosed above is only several specific embodiments of the present invention, and still, the embodiment of the present invention is not limited to this, is appointed
What what those skilled in the art can think change should all fall into protection scope of the present invention.
