Abstract
The steel pipe lightning rod disclosed by the invention for mitigating vortex-induced vibration, including column, the top of column is welded with pedestal, and ring flange has been bolted above pedestal, ring flange is provided centrally with lightning rod body, is evenly distributed with several ribs in the bottom cylindrical week of lightning rod body；The bottom of ribs is fixedly connected with the upper surface of ring flange；Coiling is fixed with steel pipe on lightning rod body.The lightning rod effectively prevent and be shaken caused by wind-force by setting steel pipe on its external wall；By setting reinforcement in lightning rod and column junction, so as to effectively avoid lightning rod root from being shaken caused by wind-force, the dual setting of steel pipe and reinforcement, it effectively prevent lightning rod and damaged caused by wind-induced vibration.
Description
Technical field
The present invention relates to lightning rod field, more particularly to a kind of steel pipe lightning rod for mitigating vortex-induced vibration.
Background technology
Many transformer stations' transmission lines of electricity are all using lightning rod at present, but traditional lightning rod is thin due to itself structure
Length, rigidity is small, shell is thin, from heavy and light, wind-induced vibration easily occurs under wind load action, for most upper in wind field windward side
The steel pipe lightning rod of trip, in the relatively low flow field of turbulence intensity and under suitable wind friction velocity, vortex-induced vibration easily occurs；And
Under the continuous action of Vortex-excited vibration Cyclic Loading, fatigue cracking can occur for steel pipe lightning rod bottom flange dish coupling bar, finally lead
The entirety of steel pipe lightning rod is caused to topple over.
The content of the invention
It is an object of the invention to provide a kind of steel pipe lightning rod for mitigating vortex-induced vibration, to solve in above-mentioned background technology
The problem of proposition.
The invention provides a kind of steel pipe lightning rod for mitigating vortex-induced vibration, including column, the top welding of the column
There is a pedestal, be bolted ring flange above the pedestal, the ring flange is provided centrally with lightning rod body, described
The bottom cylindrical week of lightning rod body is evenly distributed with several ribs；The bottom of the ribs is upper with the ring flange
Surface is fixedly connected；Coiling is fixed with steel pipe on the lightning rod body.
It is preferred that the column is internally provided with right-angled intersection ribbed stiffener.
It is preferred that a diameter of 3cm to 5cm of the steel pipe, the wall thickness of steel pipe is 0.5cm to 1cm.
It is preferred that the steel-pipe welding is on the outer wall of lightning rod body.
It is preferred that the ring flange is identical with the marginal dimension of the pedestal, the ring flange and the pedestal seam crossing
Electric welding sealing.
It is preferred that the outer surface of the column is provided with zinc coat.
It is provided by the invention mitigate vortex-induced vibration steel pipe lightning rod, the lightning rod by setting steel pipe on its external wall,
And then it effectively prevent and shaken caused by wind-force；By setting reinforcement in lightning rod and column junction, so as to
Effectively avoid lightning rod root from being shaken caused by wind-force, the dual setting of steel pipe and reinforcement, effectively prevent lightning rod
Damaged caused by wind-induced vibration.
Brief description of the drawings
Fig. 1 is a kind of steel pipe lightning rod structural representation for mitigating vortex-induced vibration provided by the invention.
Description of reference numerals：
1st, column；2nd, pedestal；3rd, ribs；4th, bolt；5th, lightning rod body；6th, steel pipe.
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 shown in figure 1, the embodiments of the invention provide a kind of steel pipe lightning rod for mitigating vortex-induced vibration, including column 1, institute
The top for stating column 1 is welded with pedestal 2, and the top of pedestal 2 is connected with ring flange, the center of the ring flange by bolt 4
Lightning rod body 5 is provided with, the lightning rod body 5 is evenly distributed with several ribs 3 bottom cylindrical week；The reinforcement
The bottom of rib 3 is fixedly connected with the upper surface of the ring flange；Coiling is fixed with steel pipe 6 on the lightning rod body 5.
Further, the column 1 is internally provided with right-angled intersection ribbed stiffener.The setting of right-angled intersection ribbed stiffener, can be with
Increase the rigidity of body in itself, reduce the wind-induced vibration of body in itself.
Further, a diameter of 3cm to 5cm of the steel pipe 6, the wall thickness of steel pipe is 0.5cm to 1cm.
Further, the steel pipe 6 is welded on the outer wall of lightning rod body 5.The welding of steel pipe, it is possible to prevente effectively from keeping away
In the relatively low flow field of turbulence intensity and under suitable wind friction velocity vortex-induced vibration occurs for thunder pin body.
Further, the ring flange is identical with the marginal dimension of the pedestal 2, and the ring flange connects with the pedestal 2
Sealing is welded at seam.
Further, the outer surface of the column 1 is provided with zinc coat.
In summary, the steel pipe lightning rod provided in an embodiment of the present invention for mitigating vortex-induced vibration, the lightning rod pass through at it
Steel pipe is set on outer wall, and then effectively prevent and shaken caused by wind-force；By being set in lightning rod and column junction
Reinforcement, so as to effectively avoid lightning rod root from being shaken caused by wind-force, the dual setting of steel pipe and reinforcement, have
Effect is avoided lightning rod and damaged caused by wind-induced vibration.
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.
