Abstract
The utility model discloses a PE cable protection tube, comprising a body. The cross section of the body is round. A lead channel is disposed in the center of the protection tube. The protection tube is characterized in that the cross section structure of the body is provided with an insulating inner layer, a protective layer, and an insulating outer layer. The protective layer is a protective net made of carbon fibers. Thickness of the inner layer is larger than that of the outer layer. The inner layer and the outer layer are insulating layers. The structural strength of the central protective layer is superior to an existing protector made of a steel material. The protective layer protects the tube from breaking by external forces, thereby effectively protecting safety of the cable in the protection tube.
Description
Technical field
The utility model relates to a kind of PE cable protection pipe.
Background technology
PE cable protection pipe is taking high-quality high-density polyethylene resin as primary raw material, adds a kind of new high-tech product of suitable adjuvants through extrusion way machine-shaping.The performance characteristics such as that this product has is corrosion-resistant, anti-aging, shock resistance, mechanical strength are high, long service life, electrical insulation properties are good, can be widely used in burying underground the field such as high-tension cable, road lighting cable protective casing.Be widely used in the places such as urban road construction, community exploitation, garden landscape, Enterprise Construction, as the wiring sheath pipe of the cables such as electric power, street lamp, Lawn lamp, garden lamp, To Intelligent Home, cable TV, communication, intelligent transportation.Existing PE cable protection pipe exists Internal cable to steal the problem of losing.
Utility model content
The problems referred to above that exist in order to solve prior art, the utility model provides a kind of PE cable protection pipe.
To achieve these goals, the utility model adopts following technical scheme:
A kind of PE cable protection pipe; there is body; described body cross-section is rounded; its middle part is provided with lead channels; it is characterized in that; described body cross-section structure has the skin of internal layer, protective layer and the insulation of insulation, and described protective layer is the catch net that carbon fiber is made, and described internal layer thickness is greater than outer layer thickness.
Preferably: described catch net aperture is 0.7-3.5cm.
Preferably: the spacing of end of described protective layer and an end of body is 2-5cm, and the spacing of another end of described protective layer and another end of body is 2-5cm.
Preferably: described external surface arranges the groove of some equidistant layouts along its length.
Compared to existing technology, the utlity model has following advantage:
(1) the utility model internal layer is insulating barrier with skin; intermediate layer protective layer structure intensity is much better than the protective that existing steel material is made; and protective layer light weight; effectively protection body is not broken by external force; effectively the safety of protection body inner cable is not also returned extra increase body weight simultaneously.
(2) the utlity model has excellent physical property, adopt high-quality polyethylene raw material to produce, both there is good rigidity, intensity, also had good flexibility, be conducive to the installation of pipeline.
(3) the utility model is corrosion-resistant, long service life.In coastal area, level of ground water is higher, soil high humidity.Use metal or other pipeline must be anticorrosion, and the life-span generally only have 30 years, and PE tubing can the medium of resistance to number of chemical, is not subject to the impact of soil corrosion.
(4) the utility model toughness is good, amount of deflection good.PE tubing is a kind of high tenacity tubing, and its elongation at break exceedes 500%.Adaptive capacity to the inhomogeneous surface subsidence in basis and dislocation is very strong.Shock resistance is good, and minor caliber pipe can be bending arbitrarily, and tube wall is smooth, and coefficient of friction is little, wears cable easy, and construction period efficiency is high.
(5) the utility model electrical insulation capability is good.Long service life (the underground pipe life-span is more than 50 years). durable in use, circuit is safe and reliable to operation.
Brief description of the drawings
Fig. 1 is PE cable protection pipe structure chart.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1; a kind of PE cable protection pipe; there is body; described body cross-section is rounded; its middle part is provided with lead channels; described body cross-section structure has the skin 3 of internal layer 1, protective layer 2 and the insulation of insulation, and described protective layer is the catch net that carbon fiber is made, and described internal layer thickness is greater than outer layer thickness.
Internal layer can select with outer the conventional material of making PE cable protection pipe; object is in order to insulate, and its primary insulation requires to be greater than its outer layer insulation requirement, therefore internal layer thickness is greater than outer layer thickness; protective layer effectively protects body not cut off (breaking), effectively takes precautions against the mistake problem of stealing.
It should be noted that, preferred as one, described catch net aperture is 0.7-3.5cm, finds that in practice the catch net effect in this aperture is better; The spacing of end of described protective layer and an end of body is 2-5cm, the spacing of another end of described protective layer and another end of body is 2-5cm, therefore body end position is not arrange protective layer, therefore can process processing to pipe end when body is laid, this does not arrange the local limited length of protective layer simultaneously, in the pipe-line system laying, can not produce too much adverse effect to antitheft mistake; Described external surface arranges the groove of some equidistant layouts along its length, therefore that outer wall has groove is thinner, is conducive to the heat radiation of body, can also effectively save material simultaneously, reduces costs.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
