Description of drawings
Accompanying drawing 2 is the combined schematic cross-section of angle steel at composite material section bar in the preferred embodiment of the present invention and right angle;
Being labeled as in the accompanying drawing: 1, body, 2, angle steel, 11, first plane, 12, second plane, 13, chamfering, 14, arc surface, 15, internal layer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
A kind of special-shaped composite material section bar that the present invention discloses, can be combined with the angle steel at right angle, be used for the special-shaped composite material section bar that power transmission and transformation shaft tower, railway electrification shaft tower or communication shaft tower are used, this abnormal shape composite material section bar has adopted insulation materials to make, thereby improves the insulating properties of whole shaft tower.
As shown in Figure 1, schematic cross-section for the composite material section bar in the present embodiment, comprise body 1, body 1 is provided with first plane 11 and second plane 12, each end on first plane 11 and second plane 12 directly is connected, the other end on first plane 11 and second plane 12 is connected by an arc surface 14, and the radian of arc surface 14 is greater than the radian of arc angling 13.
In the preferred embodiment, first plane 11 on the body 1 is connected by an arc angling 13 with an end on second plane 12, and the other end on first plane 11 and second plane 12 is connected by an arc surface 14.In addition, first plane 11 also can be carried out the right angle with second plane 12 and is connected, without chamfering.
As shown in Figure 2, the combined schematic cross-section of angle steel for composite material section bar and right angle in the preferred embodiment of the present invention, two planes among the present invention place the both sides of the angle steel 2 at right angle respectively, arc angling 13 places the place, right angle of angle steel 2, can be combined with the angle steel 2 at right angle, be used for the special-shaped composite material section bar that power transmission and transformation shaft tower, railway electrification shaft tower or communication shaft tower are used.
Referring to Fig. 1, in the embodiment of the invention, at least one surface of special-shaped composite material section bar is circular arc, because circular arc is arranged on the surface of special-shaped composite material section bar, makes this section bar surface possess to be difficult for and is stained with ash, self-cleaning and be difficult for the function of ponding.Because the surface of circular arc is easy to clean, wind and weather all will make the section bar surface be difficult for being stained with ash, be difficult for ponding.Thereby make the shaft tower that is combined by this abnormal shape composite material section bar be difficult for being stained with ash, and can be self-cleaning.
The special-shaped composite material section bar that the present invention discloses, can adopt following technology preparation:
With the non-conductive fibre impregnating resin, according to shape and the thickness of composite material section bar, the mould that the non-conductive fibre behind the impregnating resin is shaped by section bar, by pultrusion, heat, dry and solidify after, form the body of special-shaped composite material section bar.Non-conductive fibre herein can be the mutual combination of long fibre, fibrofelt, ribbon-like fibre or cloth or above-mentioned different materials; Section bar herein has the requirement of thickness and length, the application scenario different according to section bar, and thickness and length requirement have nothing in common with each other.Because resin is to immerse in the non-conductive fibre with liquid form, so resin can infiltrate through in the non-conductive fibre well.
To the body of above-mentioned shaping, can also carry out sanding and polishing and be coated with fluorine or the compound of fluorine, carry out sanding and polishing through the body outside of heating cure, the polymer coat fluorine or fluorine through the surface after the polishing forms first skin.Use the power of local weather, temperature, gradation for surface pollution and solar irradiation according to product and determine coating layer thickness, coating can primary coat, face is coated with, primary coat also can be adopted the weatherability coating good with matrix resin adhesive power, to reduce the consumption of fluorine and fluoropolymer polymer, reduces cost.But it must be the polymer of fluorine and fluorine that face is coated with.Face is coated with can one time two times, also can multipass.Also can be coated with inorganic coating by face herein, such as ceramic coating etc.
Fill insulant, to special-shaped composite material section bar internal layer 15 fill insulants, such as insulation materials such as the insulation foam of closed pore or SF6 gases, form internal layer 15, make special-shaped composite material section bar, detect then and test, see whether the composite material section bar of making is qualified, especially at aspects such as insulating properties.If filled SF6, then also need the port at composite material pole tower two ends is sealed, leak to prevent SF6.
In the process of non-conductive fibre impregnating resin or weatherability resin, can add auxiliary material, auxiliary material comprise an amount of curing compound, accelerator, filler and pigment, also can suitably add materials such as fire retardant, decide on actual demand and application.
The special-shaped composite material section bar that the present invention discloses, be provided with first plane and second plane, each end on first plane and second plane is connected by an arc angling, two planes place the both sides of the angle steel at right angle respectively, arc angling places the place, right angle of angle steel, can be combined with the angle steel at right angle, be used for the power transmission and transformation shaft tower, the special-shaped composite material section bar that railway electrification shaft tower or communication shaft tower are used, because special-shaped composite material section bar has adopted insulation materials to make, and the surface is provided with arc surface, make this section bar good insulation preformance, in light weight, have self-cleaning function, prevent dust and be difficult for being stained with ash in the surface, be difficult for ponding.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
