The engineering covered is not discovered by Party A designing unit.Because the depth of burying is not enough, electric pole Inclination Accident is caused to happen occasionally, therefore bury
If detection is particularly significant.
Again because electric pole is towering building, the center of electric pole is higher, and electric pole is typically using the moulding of truncated cone, electricity
Bar is perplexed by transverse horizontal wire tension and shaft, and longitudinally perpendicular by being oriented to beam wind tension force, electric pole stress is simultaneously non-equilibrium.
Utility model content
It is oval electric pole the utility model proposes a kind of cross section to solve the above problems, this electric pole considers
Longitudinal tension force and lateral stressed factor not etc., in the case where cross-sectional area is constant, electric pole stress is more reasonable.The electric pole master
Body be made up of composite and cross section for ellipse, and the electric pole main body on the short radial direction in its cross section with electric wire extend
In the same direction, electric pole main body is vertical with electric wire bearing of trend on its cross section major radius direction in direction.Electric pole is in the short radius in its section
The longitudinal unbalance tension force of circuit is born on direction.Cross Wind Force is resisted on the major radius direction in electric pole section.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of cross section is oval electric pole, and for installing electric wiring, the cross section of the electric pole main body is ellipse, and
On the short radial direction in its cross section with electric wire bearing of trend in the same direction, electric pole main body is in its cross section major radius side for the electric pole main body
It is vertical with electric wire bearing of trend upwards.
The utility model proposes cross section be oval electric pole in, the major radius is with the length ratio of short radius
14∶11-7∶5。
The utility model proposes cross section be oval electric pole in, the major radius is with the length ratio of short radius
21∶17。
The utility model proposes cross section be oval electric pole in, the electric pole main body is truncated cone.
It is using the beneficial effects of the utility model：
The cross section of the electric pole main body of this electric pole for ellipse, and the electric pole main body on the short radial direction in its cross section with
In the same direction, electric pole main body is vertical with electric wire bearing of trend on its cross section major radius direction so that this distribution for electric wire bearing of trend
Bar has the ability of preferably resistance crosswind, there is provided more preferably enabling capabilities.
Brief description of the drawings
Fig. 1 is the overall schematic that a kind of cross section of the utility model is oval electric pole.
Fig. 2 is the sectional view in the utility model Fig. 1 along A-A directions.
Fig. 3 is the position view in another embodiment of the utility model.
Reference includes：
The 100- electric pole main body 110- major radius short radiuses of 120-
200- cables
Specific embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
Embodiment 1
As shown in figure 1, a kind of cross section is oval electric pole, for installing electric wiring, electric pole main body is by composite system
Into and cross section for ellipse, and the electric pole main body on the short direction of radius 120 in its cross section with electric wire bearing of trend in the same direction, electricity
Bar main body is vertical with electric wire bearing of trend on its direction of cross section major radius 110.
Specifically, power distribution rod is the bridge of electricity, electricity transport to each place is allowed, people can be according to circuit and job facilities
Need for power distribution rod to be embedded in each position, such as other are local for river shoal, sandy land, high mountain, to meet the production and life of people
It is living to need.And due to power engineering the need for, some power distribution rods need transport on the high mountain of several kms of height above sea level.
Such as under no-wind environment, the component of the main gravity by electric wire of side force that electric pole main body 100 is subject to is provided, at this
In embodiment, on the short direction of radius 120 in its cross section with electric wire bearing of trend in the same direction, electric pole both sides wire pair is electric for electric pole main body
The pulling force that bar is formed is cancelled out each other.
In the case where actual environment has beam wind, stress of the electric pole on its direction of cross section major radius 110 is main by horizontal stroke
Wind is produced, and the support force provided on the direction of major radius 110 of electric pole main body 100 supports the tension force that beam wind is produced enough, special
Under the conditions of, such as at mountain pass, electric pole meets the crosswind received than larger, and crosswind is larger to the side force that electric pole main body 100 is formed, this electric pole
Cause that this electric pole can be used in the bigger place of wind speed by the way that major radius 110 is vertical with electric wire bearing of trend.
As shown in Fig. 2 in the present embodiment, major radius 110 is 14: 11-7: 5 with the length ratio of short radius 120.Wherein,
The length ratio of major radius 110 and short radius 120 meets the requirement of GB50545-2010 and DL/T5254-2010 according to calculating.
Specifically, major radius 110 and the length ratio of short radius 120 are 21: 17.
In the present embodiment, electric pole main body 100 is truncated cone.The root cross-sectional area of electric pole main body 100 is larger, electric pole master
The top rank street area of body 100 is smaller.

The cross section proposed in the present embodiment is that the cross section of proposition in oval electric pole and embodiment 1 is oval
Electric pole is similar to, and difference is electric pole main body 100.
In the present embodiment, electric pole main body 100 is tubulose, and the cross section of electric pole main body 100 is oval ring surface.With
Embodiment 1 is similar to, and electric pole main body 100 is in the same direction with electric wire bearing of trend on its direction of cross section major radius 110, electric pole main body
100 is vertical with electric wire bearing of trend on the short direction of radius 120 in its cross section.
Embodiment 3
Electric pole main body 100 can polyurethane material be made, in its cross section, major radius 110 is with the length ratio of short radius 120
42∶34。
Embodiment 4
As shown in figure 3, in the present embodiment, to deliver electric pole, cable 200 does not exist this power distribution rod in the both sides of electric pole main body 100
On same straight line, in the present embodiment, angle is formed between the both sides cable 200 of electric pole main body 100, figure center line B is electric pole main body
Bisector of angle is pressed from both sides between 100 both sides cables 200.Major radius 110 overlaps with the bisector in electric pole main body 100.
Cable 200 is bisector line B directions to the resultant direction of the pulling force of electric pole main body 100, long by half in electric pole main body 100
Footpath 110 overlaps with bisector line B so that electric pole main body 100 has more preferable enabling capabilities to the pulling force that cable 200 is formed.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
