Abstract
The utility model discloses a kind of low-resistance wear-resistance burning into sand plastic steel composite cable conduit with salient point, one comprises interior pipe and is wrapped in the glass fiber of described inner tube outer surface, it is characterized in that: described inner tube outer surface is provided with salient point, between described glass fiber and described interior pipe, be provided with quartz sand.The material of described interior pipe is PVC, polyethylene or polypropylene.The hemisphere of described salient point to be diameter be 1mm is that 2mm linear array is arranged in described inner tube outer surface according to spacing.Described glass fiber is alkali-free glass wool.The utility model reasonable in design, the glass reinforced plastic pipe that glass fiber is wound and interior pipe can be combined into as a whole closely, at the hemisphere salient point that inner tube outer surface is provided with, increase the frictional force between glass fiber and interior pipe, avoid stressed rear inner and outer pipes and be separated.
Description
Technical field
The utility model relates to a kind of low-resistance wear-resistance burning into sand plastic steel composite cable conduit with salient point.
Background technology
Pipe material market being used as plastic cable protection has two large classes substantially, and one is thermoset plastics, and wherein based on GRP pipe, another kind is thermoplastics, based on PVC, polyethylene, PA tube.The pluses and minuses of the pipeline of this two large types of material are as follows:
The advantage in frp cable protective pipe road: (1) GRP pipe is lightweight, rigidity is high, resistance to compression and anti-settling ability strong; (2) conductive coefficient is large, and when especially cable runs in underground for a long time, advantage is more obvious; (3) the resistance to temperature difference is good, and in-40 DEG C ~-150 DEG C environment, service life can reach 50 years.Manufacturing in a rough and slipshod way due to the defect of technique own and illegal producer in frp cable protective pipe road, serves as without alkali product with high alkali product, the factor such as to adulterate; its quality is uneven; cannot stand the friction of traction steel wire, scuffing when wearing cable, result in glass fibre delamination, cause glass fibre to be entangled on cable; twine more and more; can not advance, can not retreat, cause wearing cable failure; the object that safety wears cable can not be realized, be faced with the danger be eliminated.The advantage of the thermoplastic pipes such as PVC, polypropylene, polyethylene is a lot, is applied in cable protection field, and outstanding feature is exactly that electrical insulating property is good, inwall smoother, easily cabling, and the phenomenon of stuck cable can not be caused to occur.But heat-resisting, cold-resistant have limitation, be difficult to the needs reaching power industry technical requirement.Thermoplastic tubing is tubing more common on market above, respectively has pluses and minuses, but the requirement of distance power industry falls far short.
Utility model content
The utility model, for above problem, provides a kind of heat-resisting, high-strength, lightweight, corrosion resistant, fire-retardant, inner wall smooth and composite cable conduit economical and practical again.
The technical solution adopted in the utility model is as follows:
With a low-resistance wear-resistance burning into sand plastic steel composite cable conduit for salient point, comprise interior pipe and be wrapped in the glass fiber of described inner tube outer surface, described inner tube outer surface is provided with salient point, between described glass fiber and described interior pipe, be provided with quartz sand.
Preferably, the material of described interior pipe is PVC, polyethylene or polypropylene.
Preferably, the hemisphere of described salient point to be diameter be 1mm is that 2mm linear array is arranged in described inner tube outer surface according to spacing.
Preferably, described glass fiber is alkali-free glass wool.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The interior pipe that in this pipe, pipe uses PVC, polyethylene, polypropylene material to make, outside interior pipe, carrying out winding glass fiber, for ensureing interior pipe and outer tube (glass fiber layer), being provided with hemisphere salient point at inner tube outer surface, for meet the requirement of environmental protection, have employed alkali-free glass wool.
Accompanying drawing explanation
Fig. 1 is the utility model tube wall schematic cross-section.
Embodiment
Below in conjunction with the drawings and specific embodiments to the further detailed description of the utility model:
Shown in accompanying drawing 1, a kind of low-resistance wear-resistance burning into sand plastic steel composite cable conduit with salient point, comprise interior pipe 1 and be wrapped in the glass fiber 2 of described interior pipe 1 outer surface, described interior pipe 1 outer surface is provided with salient point 3, between described glass fiber 2 and described interior pipe 1, be provided with quartz sand 4.
As preferably, the material of described interior pipe 1 is PVC, polyethylene or polypropylene.
As preferably, described salient point 3 is the hemisphere of 1mm for diameter, is that 2mm linear array is arranged in described interior pipe 1 outer surface according to spacing.
As preferably, described glass fiber 2 is alkali-free glass wool.
The utility model cable duct tube adopts three-decker, the interior pipe 1 that ground floor uses PVC, polyethylene, polypropylene material to make, and ensure that the level and smooth of inner surface, very strong to threading; The hemisphere salient point 3 that interior pipe 1 outer surface is provided with makes quartz sand layer and glass fiber layer tightly be attached on interior pipe 1, increasing friction force, avoids stressed rear inner and outer pipes and is separated.For meet the requirement of environmental protection, have employed alkali-free glass wool.The utility model not only extends the useful life of cable, has ensured the safety of operation of power networks, has also made great contribution to environmental protection cause.
