Abstract
The utility model provides a thermosetting resin fiber reinforcement cable protection pipe belongs to cable protection pipe field. This thermosetting resin fiber reinforcement cable protection pipe, its inlayer has thermosetting resin's fibrofelt winding layer for the flooding, the wholeness is better, the silk that can not appear loosing blocks a cable, avoid card to die the cable phenomenon and take place, in addition owing to its to contain thermosetting resin content higher, the cable threading conveniently carries out, the outside roving fibre cloth winding layer that has a thermosetting resin for the flooding in proper order and flooding have thermosetting resin's spun yarn fibre cloth winding layer, because outmost for the flooding has thermosetting resin's spun yarn fibre cloth, since like this, have just made the cable protection tube -surface of produce smooth, wholly beautifully, the cable protection pipe of producing can satisfy the requirement of axial strength, hoop intensity and bearing capacity.
Description
Technical field
The utility model relates to cable protection pipe technical field, and specifically a kind of thermoset resin fibres strengthens cable protection pipe.
Background technology
Along with the develop rapidly of communication cable and power cable; the application of cable in our daily life is more extensive; act on also further important, and require also more and more higher for the protection of cable, necessarily require cable protection pipe to have certain intensity and anti-pressure ability.
Thermoset resin fibres strengthen cable protection pipe lightweight with it, rigidity is high, resistance to compression and anti-settling ability strong; Conductive coefficient is large, especially cable for a long time when low operation advantage more obvious; Good weatherability; in-40 DEG C ~ 150 DEG C environment service life the advantage such as can reach 50 years; become the preferred tubing of power cable company modular design; and this cable protection pipe is in the cable threading process in later stage; once cause the scuffing of inwall, just there will be fiber delamination, cause cable to be stuck; can not threading be continued, exit even the destruction all causing pipeline.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides a kind of structure thermoset resin fibres that is simple, that effectively can prevent fiber filoselle to strengthen cable protection pipe.
The utility model solves the technical scheme that its technical problem adopts:
A kind of thermoset resin fibres strengthens cable protection pipe, the fibrofelt winding layer being impregnated with thermosetting resin comprising from inside to outside compound successively, the roving fibers cloth winding layer being impregnated with thermosetting resin and be impregnated with the yarn strands cloth winding layer of thermosetting resin.
Described fibrofelt winding layer, the roving fibers cloth winding layer being impregnated with thermosetting resin and the yarn strands cloth winding layer that is impregnated with thermosetting resin being impregnated with thermosetting resin successively to be suppressed through thermosetting resin and curing agent by fibrofelt, roving fibers cloth and yarn strands cloth respectively and is formed.
The content of thermosetting resin contained by the described yarn strands cloth winding layer being impregnated with thermosetting resin by weight percentage, lower than the content 20-40% of thermosetting resin contained by the fibrofelt winding layer being impregnated with thermosetting resin.
Described Fiber Materials is one or more in glass fibre, carbon fiber, basalt fibre.
Thermoset resin fibres of the present utility model strengthens cable protection pipe, and compared with prior art, the beneficial effect produced is,
1, thermoset resin fibres strengthens cable protection pipe, its innermost layer is the fibrofelt winding layer being impregnated with thermosetting resin, because fibrofelt adopts the disorderly and unsystematic accumulation of chopped strand to make, all directions stress equalization, globality is better, there will not be filoselle to block cable, stuck cable phenomenon is avoided to occur, but its draw ratio is relatively little, if all adopt fibrofelt, then its intensity is bad;
Outwards be followed successively by the roving fibers cloth winding layer being impregnated with thermosetting resin and the yarn strands cloth winding layer being impregnated with thermosetting resin, form because coarse sand fiber cloth and fine sand fiber cloth (the two is fiber cloth) adopt long fibre to weave in order, if all adopt fiber cloth, cause that product is finally stressed also will consider different directions;
In view of above 2 points, the mode adopting fibrofelt to be combined with fiber cloth, can meet the requirement of axial strength, hoop intensity and bearing capacity like this.
2, thermoset resin fibres strengthens cable protection pipe, and its outermost layer is the yarn strands cloth being impregnated with thermosetting resin, like this, has just made produced cable protection pipe smooth surface, overall appearance.
3, the content of thermosetting resin contained by the yarn strands cloth winding layer being impregnated with thermosetting resin by weight percentage, lower than the content 20-40% of thermosetting resin contained by the fibrofelt winding layer being impregnated with thermosetting resin, such structural design can reduce the frictional resistance of cable tube inwall, facilitates the cable threading in later stage.
To sum up, the thermoset resin fibres that the utility model is produced strengthens cable protection pipe, and its structure is simple, reasonable in design; overall appearance; fiber filoselle can not only be prevented, avoid occurring card cable phenomenon, it can also be made to meet the requirement of axial strength, hoop intensity and bearing capacity.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model thermoset resin fibres enhancing cable protection pipe.
In figure, 1, be impregnated with the spun yarn glass fabric winding layer of thermosetting resin, 2, be impregnated with the roving glass fibers cloth winding layer of thermosetting resin, 3, be impregnated with the glass mat winding layer of thermosetting resin.
Embodiment
Below in conjunction with accompanying drawing 1, cable protection pipe is strengthened to a kind of thermoset resin fibres of the present utility model, be described in detail below.
As shown in Figure 1; a kind of thermoset resin fibres of the present utility model strengthens cable protection pipe, the glass mat winding layer 3 being impregnated with thermosetting resin comprising from inside to outside compound successively, the roving glass fibers cloth winding layer 2 being impregnated with thermosetting resin and be impregnated with the spun yarn glass fabric winding layer 1 of thermosetting resin.
Wherein, the glass mat winding layer 3 being impregnated with thermosetting resin, the roving glass fibers cloth winding layer 2 being impregnated with thermosetting resin and the spun yarn glass fabric winding layer 1 being impregnated with thermosetting resin successively to be suppressed through thermosetting resin and curing agent by glass mat, roving glass fibers cloth and spun yarn glass fabric respectively and are formed.
The content of thermosetting resin contained by the spun yarn glass fabric winding layer 1 being impregnated with thermosetting resin by weight percentage, lower than the content 20-40% of thermosetting resin contained by the glass mat winding layer 3 being impregnated with thermosetting resin.
In the present embodiment, glass mat according to actual needs, the at least one in carbon fiber felt, basalt fibre felt can be selected to substitute, accordingly, roving glass fibers cloth can be substituted by least one in rove carbon cloth, rove basalt fiber cloth, and spun yarn glass fabric can be substituted by least one in spun yarn carbon cloth, spun yarn basalt fiber cloth.
