The flexible anticorrosion anode of the utility model is convenient for installation and not easy to be damaged; moreover; the flexible anticorrosion anode has good flexibility, anti high and low temperature property and ultraviolet resistance ability, and can not cause heavy metal pollution on water and soil when being buried under ground for a long time; the flexible anticorrosion anode has the function of reducing ground resistance and can prolong life service; and the flexible anticorrosion anode also has good electrochemical property, thus being able to work reliably for a long time; the flexible anticorrosion anode can lead cathodic protection current to be distributed evenly and can fully play the role of the protection measure of the cathode of an impressed current, and meanwhile, avoids the problems of hydrogen evolution and coating peeling caused by local overprotection. The flexible anticorrosion anode of the utility model can control the electrochemical corrosion of such metal structures as underground pipelines and oil storage tanks, etc.
Description
Technical field
The utility model relates to a kind of grounding device, particularly relates to a kind of novel flexible corrosion protection anode that is applied to the impressed current galvanic protection of steel pipe and petroleum storage tank etc.
Background technology
The impressed current cathode protection measure is often adopted in the corrosion control of steel pipe and petroleum storage tank etc.The supplementary anode of the existing impressed current galvanic protection of generally using has high silicon cast-iron anode, graphite anode, iron and steel anode and common flexible anode etc.High silicon cast-iron anode, graphite anode, when the iron and steel anode is used for supplementary anode, construction difficulty not only, and easily produce the cathodic protection current problem of uneven distribution.Common flexible anode exists snappiness difference and the relatively poor defective of resistant of high or low temperature; When adopting stopping composition, this anode construction is than difficulty and easily produce the loose problem of stopping composition in addition.
Summary of the invention
Technical problem to be solved in the utility model is: at the deficiency of existing supplementary anode technology, a kind of novel flexible corrosion protection anode is provided, prevent underground pipeline to be applicable to, the especially galvanic corrosion of metallic structures such as the old pipeline of coating damage and petroleum storage tank control.
The technical scheme that its technical problem that solves the utility model adopts is: comprise copper conductor, be coated with one deck conductive rubber at the skin of copper conductor; Coated outside at conductive rubber has erosion-resisting fabric protective layer, is filled with coke between them; Coated outside at the fabric protective layer has one deck fibrous braid.
The utility model is compared with existing supplementary anode, and its major advantage is: the one, and radius-of-curvature is less, is easy to install, not easy damaged; The 2nd, adopt the anticorrosion conductive rubber material that does not contain heavy metal, have good flexibility, resistant of high or low temperature and ultraviolet-resistant capacity, imbed for a long time and undergroundly can not cause heavy metal contamination water, soil, meet the environmental requirement of country; The 3rd, the coke layer that adopts has the function that reduces stake resistance, and can prolong the work-ing life of this flexible corrosion protection anode; The 4th, adopted fabric and fibrous braid, but the STRENGTH ON COKE layer shields.In addition, also have good electrochemical, can work stably in a long term; Can make the cathodic protection current uniform distribution, can give full play to the effect of impressed current cathode protection measure, avoid simultaneously producing liberation of hydrogen and coating stripping problem because of local overprotection.
The utility model is applicable to and prevents underground pipeline, the especially galvanic corrosion of metallic structures such as the old pipeline of coating damage and petroleum storage tank control.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The flexible corrosion protection anode that the utility model provides, its structure be as shown in Figure 1: comprise copper conductor 1, its skin is coated with one deck conductive rubber 2; Coated outside at conductive rubber 2 has erosion-resisting fabric protective layer 4, is filled with coke 3 between them; Coated outside at fabric protective layer 4 has one deck fibrous braid 5.
Described conductive rubber 2, it has the output that good electrical conductivity is beneficial to cathodic protection current, has good flexibility and is beneficial to reduce contact resistance and convenient construction, also has splendid resistant of high or low temperature and UV resistant, ozone ability.
Described coke 3, its purity should be selected for use up to more than 99%, and this coke has good electrical conductivity, can reduce the stake resistance of flexible corrosion protection anode, and copper conductor 1 and conductive rubber 2 are shielded.
Described fabric protective layer 4, the woven that can make by materials such as polyamide fibre, terylene, polypropylene fibre.The effect of fabric protective layer 4 is stationary coke.
Described fibrous braid 5 can be formed by nylon, the braiding of EVA materials such as (ethylene-vinyl acetate copolymers), is netted, is wrapped in the outside of fabric protective layer 4.The effect of fibrous braid 5 is to protect flexible corrosion protection anode in construction.
The flexible corrosion protection anode that the utility model provides near the protected object that can be laid in (for example steel pipe or petroleum storage tank), adopts the construction technology of similar buried cable when reality is used, comparatively simple and easy.Flexible corrosion protection anode is as supplementary anode, can link to each other with the positive pole of the power unit of impressed current cathodic protection system, and protected object links to each other with the negative pole of power unit.The anodal effusive protective current of power unit flows to protected object by flexible corrosion protection anode equably via soil, thereby the control protected object suffers galvanic corrosion.
