Description
Technical field
The present invention relates to lightning rod technical field, is a kind of steel pipe lightning rod for mitigating wind-induced vibration.
Background technology
To prevent influence of the thunder and lightning to transformer station's transmission line of electricity, lightning rod is widely used in high voltage substation, and it belongs to high
Alarm cantilever member, have the characteristics that slenderness ratio is big, rigidity is small, shell is thin, from heavy and light, be typical wind sensitive structure, easily exist
Wind-induced vibration occurs under wind action, wind load often turns into one of primary load of control structure design；On the other hand, I
Before the substation section addressing Yushan Hill of the Northwest of state on the Gobi desert of alluviation flood sector, physical features is open in site, subregion
The average maximum wind velocities of the interior 50 years one high 10min of 10m met reach 36.1m/s, and corresponding blast reaches 0.81kN/m2, and annual is big
Wind number of days 148.1 days, most Windy Days 202 days（More than 7 grades are strong wind, wind speed about 17m/s）, belong to continual strong wind environment,
The probability that Lightning-Rod Protection Disign In Substations generation wind under this specific harsh weather ruins accident will greatly increase.
The content of the invention
The invention provides a kind of steel pipe lightning rod for mitigating wind-induced vibration, the deficiency of above-mentioned prior art is overcome, its
Can effectively solve lightning rod wind-induced vibration easily occurs under wind action and reduces the power transformation under harsher wind conditions harsh weather
The problem of wind ruins the probability of accident, occurs for lightning rod of standing.
The technical scheme is that realized by following measures：A kind of steel pipe lightning rod for mitigating wind-induced vibration,
Including lightning rod body and steel pipe, coiling is fixed with steel pipe from bottom to top on lightning rod body.
Here is the further optimization and/or improvements to foregoing invention technical scheme：
Above-mentioned lightning rod body includes hypomere, stage casing and epimere, and hypomere and stage casing are fixedly installed togather, stage casing and epimere
It is fixedly installed togather, hypomere, stage casing and epimere link together tapered structure.
Above-mentioned hypomere, stage casing are identical with the wall thickness of epimere, and hypomere, stage casing and epimere wall thickness are 4cm to 8cm.
A diameter of 3cm to 5cm of above-mentioned steel pipe, the wall thickness of steel pipe is 0.5cm to 1cm.
Above-mentioned hypomere and stage casing are fixed together by flange, and stage casing and epimere are fixedly connected on one by flange
Rise.
Above-mentioned steel-pipe welding is on the outer wall of lightning rod body.
Reasonable and compact in structure of the present invention, it is easy to use, steel pipe is wound with lightning rod outer wall, in lightning rod wind-engaging
When, its leeward side will not form stable vortex, can effectively improve lightning rod starting of oscillation wind speed, and it is same to mitigate lightning rod wind-induced vibration
When the Lightning-Rod Protection Disign In Substations wind that reduces under harsher wind conditions harsh weather ruin the generation of accident.
Brief description of the drawings
Accompanying drawing 1 is the main structure diagram of preferred embodiment.
Coding in accompanying drawing is respectively：1 is hypomere, and 2 be stage casing, and 3 be epimere, and 4 be steel pipe.
Embodiment
The present invention is not limited by following embodiments, can technique according to the invention scheme and actual conditions it is specific to determine
Embodiment.
In the present invention, for the ease of description, the description of the relative position relation of each part is according to Figure of description 1
Butut mode be described, such as：The position relationship of upper and lower, left and right etc. is that the Butut direction of foundation Figure of description is come
Determine.
With reference to embodiment and accompanying drawing, the invention will be further described：
As shown in Figure 1, the steel pipe lightning rod of the mitigation wind-induced vibration includes lightning rod body and steel pipe 4, in lightning rod
Coiling is fixed with steel pipe 4 from bottom to top on body.In use, spiralling steel pipe 4, in lightning rod body wind-engaging, its is leeward
Side will not form stable vortex, mitigate lightning rod body wind-induced vibration.
The steel pipe lightning rod of above-mentioned mitigation wind-induced vibration can be made further optimization and/or improvements according to being actually needed：
As shown in Figure 1, lightning rod body includes hypomere 1, stage casing 2 and epimere 3, and hypomere 1 and stage casing 2 are fixedly mounted on one
Rise, stage casing 2 and epimere 3 are fixedly installed togather, and hypomere 1, stage casing 2 and epimere 3 link together tapered structure.So, just
Path is formed in powered cloud layer and lightning rod body, and lightning rod body is ground connection, so as to which the electric charge of powered cloud layer is led
Enter the earth.
As needed, hypomere 1, stage casing 2 are identical with the wall thickness of epimere 3, hypomere 1, stage casing 2 and the wall thickness of epimere 3 be 4cm extremely
8cm.So, it is easy to preferably be fixed on building.
As needed, a diameter of 3cm to 5cm of steel pipe 4, the wall thickness of steel pipe 4 is 0.5cm to 1cm.So, in order to more preferable
Reduction lee face stabilizing vortex wind speed.
As shown in Figure 1, it is fixed together for the ease of installing/dismounting, hypomere 1 and stage casing 2 by flange, stage casing 2
It is fixed together with epimere 3 by flange.
As shown in Figure 1, steel pipe 4 is welded on the outer wall of lightning rod body.So, preferably steel pipe 4 can be fixed.
Above technical characteristic constitutes highly preferred embodiment of the present invention, and there is stronger adaptability and optimal implementation to imitate for it
Fruit, can be according to the non-essential technical characteristic of increase and decrease be actually needed, to meet the needs of different situations.
