Abstract
The utility model discloses a reinforced pipe for a deeply buried electric cable, and the reinforced pipe for a deeply buried electric cable comprises a steel pipe, wherein the inner wall of the steel pipe is provided with a spiral groove, the inner and outer walls of the steel pipe are coated with epoxy resin layers, and the epoxy resin layers are coated with ceramic corrosion-resisting layers. The reinforced pipe for a deeply buried electric cable is characterized in that the reinforced pipe is novel in structural design; after the reinforced pipe for a deeply buried electric cable is applied, a gap is formed between the reinforced pipe and a cable core through the spiral groove of the inner wall of the steel pipe; air mediums can be increased, the stability of signal transmission can be improved, the epoxy resin layers and the ceramic corrosion resisting layers can prevent the steel pipe from electrochemical corrosion, and the service life can be prolonged.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of buried cable reinforced pipe.
Background technology:
Cable tube is embedded in underground, in it, wears cable, mainly protects cable in use not by damages such as outside destroy, corrosive liquids infiltrations, therefore requires cable tube should have certain intensity, permeability resistance, resistance to compression and bend resistance performance.
At present, resistance to compression, the bend resistance performance mostly selecting common steel tube or coating steel pipe to make cable tube to meet cable tube, but common steel tube or coating steel pipe easily are corroded, and simultaneously, after application, stable signal transmission is poor, and range of application is quite narrow.
The utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of buried cable reinforced pipe, the structural design advantages of simple, and cable tube is corrosion-resistant, electrical insulation capability good, and stable signal transmission is good.
The technical solution of the utility model is as follows:
Buried cable reinforced pipe, comprise steel pipe, it is characterized in that: described steel pipe inner wall is provided with spiral groove, and the inside and outside wall of steel pipe is coated with epoxy resin layer, and epoxy resin layer is coated with the ceramic anti-corrosion layer outward.
Described buried cable reinforced pipe is characterized in that: described epoxy resin layer adopts electrostatic spraying and the steel pipe outside, and thickness is greater than 350 μ m.
Described buried cable reinforced pipe is characterized in that: the thickness of described ceramic anti-corrosion layer is greater than 550 μ m.
The utility model has the advantages that:
, by the steel pipe inner wall spiral groove, there is space in the utility model structural design novelty after application and between cable core, can increase air dielectric, improve the stability of signal transmission, epoxy resin layer and ceramic anti-corrosion layer can be stopped steel pipe and be subject to electrochemical corrosion, increase the service life.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Buried cable reinforced pipe, comprise steel pipe 1, and steel pipe 1 inwall is provided with spiral groove 2, and the inside and outside wall of steel pipe 1 is coated with epoxy resin layer 3, and epoxy resin layer 3 is outer is coated with ceramic anti-corrosion layer 4, can stop steel pipe and be subject to electrochemical corrosion, increases the service life.
Epoxy resin layer 4 adopts electrostatic spraying and the steel pipe outside, and thickness is greater than 350 μ m, also can improve the insulation property of cable.
The thickness of ceramic anti-corrosion layer 4 is greater than 550 μ m, improves decay resistance.
