Description
Technical field
The utility model is related to a kind of electric pole more particularly to a kind of composite material electric poles.
Background technology
Electric pole is the bridge of electricity, and electricity is allowed to transport each place, we have wooden electric pole by common electric pole, there is cement electricity
Bar, their height differ, and stand in Plain intermountain, spread over around people.There are many total class of electric pole, it is common as：Coagulation
Electric pole made of native electric pole concrete pole concrete and rebars or steel wire.Iron：The electric pole being cast by iron, coagulation
Native electric pole has prestressing force and two kinds non-prestressed.The section form of electric pole have rectangular, octagonal, it is I-shaped, annular or other one
A little profiled-cross-sections.Commonly used is ring section and square-section.Electric pole length is generally 4.5~15 meters.These types of electric pole
Dead weight it is larger, transport, installation are inconvenient.
With the development of society, composite material is widely applied in power industry, composite material electric pole is increasingly becoming
The trend of development, people devise the compound electric pole of form.But existing composite bar is using thin-wall circular canalis spinalis structure, one
As using winding shaping process, the angle of glass fibre when being wound by reducing improves the whole anti-bending strength of bar.But for electricity
The composite material natural resiliency modulus that bar makes is small, is easily deformed, so under special operation condition, when composite bar is by additional
During load, amount of deflection often can be exceeded, forms the security risk of circuit operation.Or people by the use of pultrusion section bar in
Column, then its outer winding composite fibre again, but this compound electric pole is on the one hand since the size of electric pole is very big, using this side
It is very high that formula makes requirement of the section bar to equipment, it is difficult to and it is extensive to implement, and production cost is too high；On the other hand due to pultruded
Material length is long, and rigidity, anti-bending strength are difficult to ensure that.
Utility model content
The purpose of this utility model is to provide the composite material electric poles that a kind of tensile strength is high, anti-bending strength is strong.
This composite material electric pole provided by the utility model, including the body of rod, the body of rod includes liner fixture, outer winding
Layer and positioned at several drawing and extruding section bars between the two, each drawing and extruding section bar is removably connected on liner fixture, about the body of rod
Longitudinal center line circular array is set, and is locked by outer wrap.
In a specific embodiment, making the liner fixture, outer wall is evenly equipped with several card slots for cylinder type fixture.
In this specific embodiment, make the card slot for half slot, the drawing and extruding section bar is in elastic conjunction and card slot
Hollow cylinder.
As another embodiment, making the liner fixture, the region between adjacent both sides is formed for cross fixture
Right angle slot.
Match, the section for making the drawing and extruding section bar is fan type, and the right angle of the liner fixture is plugged in its inner end
In slot.
It is Nian Jie with being equipped on the fitting surface of the liner fixture in the drawing and extruding section bar in order to improve the reliability of grafting
Layer.
The body of rod of the utility model includes inside and outside two layers；Wherein internal layer by liner fixture and several drawing and extruding section bars assembling and
Into on the one hand can reducing the sectional area of single drawing and extruding section bar, requirement of the section bar to former can be reduced, reduction is produced into
This；On the other hand multiple drawing and extruding section bars are provided in equal sectional area, cross sectional moment of inertia can be increased, promote anti-bending strength
And tensile strength.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the preferred embodiment in the utility model one.
Fig. 2 is the schematic cross-sectional view of the preferred embodiment in the utility model two.
Illustrate serial number：
1-liner fixture, 11-card slot, 2-drawing and extruding section bar, 3-outer wrap,
10-liner fixture I, 20-drawing and extruding section bar I, 4-adhesive linkage.
Specific embodiment
Preferred embodiment one, as shown in Figure 1, the body of rod of this composite material electric pole provided in this embodiment is included from introversion
Liner fixture 1, drawing and extruding section bar 2 and the outer wrap 3 set gradually outside.
Liner fixture 1 is cylinder type fixture, and outer wall is evenly equipped with multiple semi-circular card slots 11.
Drawing and extruding section bar 2 is the hollow cylinder for being matched with card slot 11.
In actual use, then composite fibre is wound in by each drawing and extruding section bar elastic conjunction in corresponding card slot
Outer wrap 3 is formed outside the assembly parts.
Preferred embodiment two, as shown in Fig. 2, the body of rod of this composite material electric pole provided in this embodiment is included from introversion
Liner fixture I 10, drawing and extruding section bar I 20 and the outer wrap 3 set gradually outside.
Can be cross fixture by liner fixture I 10, the region between adjacent both sides forms right angle slot.
The section of drawing and extruding section bar I 20 is fan type, is plugged in the right angle slot of liner fixture with its inner end.And in pultrusion
The fitting surface of section bar I and liner fixture I is equipped with adhesive linkage 4 to improve the reliability of grafting.
In actual use, adhesive linkage is coated in the right angle slot of liner fixture I, is then plugged in drawing and extruding section bar I
In right angle slot, then composite fibre is wound in outside the assembly parts and forms outer wrap 3.
In utility model, the internal layer of the body of rod is that the composite material section bar of pultrusion arranges, and is consolidated using liner fixture
It is fixed；Outer layer uses winding process, and internal layer is wrapped up, is finally solidified into one.By this structure type, using multiple pultrusions
Molding composite material section bar is assemblied on liner fixture, on the one hand can enlarging section the moment of inertia, promote its anti-bending strength, greatly
It is big to promote section tensile strength；On the other hand it can reduce the diameter of each hollow cylinder, reduce the requirement for production equipment, save
About cost of manufacture.
