Abstract
The utility model discloses a long life buried copper and cupric sulfate reference electrode, being applied to the electrochemical field for the cathodic protection of buried pipelines, cables, metal structures, etc. A novel manufacturing scheme is proposed via the update of the structural design. The long life buried copper and cupric sulfate reference electrode comprises a ceramic jar, helical copper wires, cupric sulfate crystals, sealing fillers, cables, etc. The helical copper wire and the cupric sulfate crystals are sealed inside the ceramic jar via the sealing fillers for implementing the reversibility, non-perishable polarizability, stability, and reproducibility of the electrode. The utility model has the advantages of easy fabrication and convenient maintenance, and the service life thereof can reach more than ten years. By the field burial experiment, the utility model has excellent effect.
Description
Long-life buried copper copper sulphate reference electrode is applicable to the electrochemical field such as cathodic protection of buried pipeline, cable and metal structures.
At present, have at the reference electrode that electrode potential adopted of monitoring metal or structures both at home and abroad: copper copper sulphate reference electrode, silver; The silver chlorate reference electrode; Zinc and kirsite reference electrode and Gan Gong electrode.Above-mentioned electrode has two kinds of operating states, and a kind of is the portable type measuring type, and a kind of is to bury the ground type for a long time.Though portable fluid copper copper sulfate electrode is desirable, concerning tens in addition pipeline, cable and the metal structures of hundreds of kilometer, it is very inconvenient to measure.Burying under the ground condition, the reference electrode majority is a liquid, and is bad because of sealing, seepage is serious, to making the life-span short then several days, and the longest some months.And contaminated electrode makes its inefficacy owing to foreign ion in the soil environment enters solution.Therefore, in the test, change electrode interior solution constantly, upgrade electrode surface at the scene, bring a lot of troubles to the cathodic protection management, and, the cathodic protection effect is affected because of electrode failure.
In view of existing problem in the above-mentioned prior art, task of the present utility model is: design a kind of rational in infrastructurely, be easy to manufacture, and functional, the buried copper copper sulphate reference electrode of long service life.
Ceramic pot helical form copper wire, copper sulfate crystal, epoxy putty airtight and watertight padding and sealed disc, seal cover and cable that the utility model is manufactured by ceramic semipermeable membrane material constitute, helical form copper wire and copper sulfate crystal are sealed in the ceramic pot with airtight and watertight padding, and helical form copper wire and cable join.
To narrate the instantiation of the copper copper sulphate reference electrode of manufacturing by the utility model below, therefrom can find out more advantages of the present utility model, consult accompanying drawing one width of cloth in the narration.
Fig. 1: long-life buried copper/copper sulphate reference electrode structural representation.
As shown in Figure 1, long-life buried copper copper sulphate reference electrode is to be made of ceramic pot (1), helical form copper wire (2), copper sulfate crystal (3), epoxy putty airtight and watertight padding (4), sealed disc (5), seal cover (6), cable (7) that the semi-transparent membrane type material of pottery is manufactured.
Copper copper sulphate reference electrode is no matter its version how, but all has one can allow the pellicle that ion passes through or the ceramic pot (1) of similar structures, this material no matter the size restriction can be processed into difformity, and have certain mechanical strength.Helical form copper wire (2) and copper sulfate crystal (3) are sealed in the ceramic pot (1) with epoxy putty airtight and watertight padding (4), make it to form structure of whole solid state, guaranteeing has sufficient copper sulfate crystal in the electrode body.Whole ceramic pot surface can be by ion and with extraneous conducting, this has just strengthened the contact area of electrode and medium, helps the anti-polarization performance of the stable and electrode of electrode potential.Ceramic pot (1) volume is bigger, and interior dress copper copper sulfate crystal is many, thereby reaches the purpose that prolongs electrode life.Helical form copper wire (2) joins by sealed disc (5) and cable by seal cover (6), just can measure bury the cathode protecting state of facility.
For guaranteeing the useful life of copper copper sulphate reference electrode, reduce the loss of copper sulfate crystal in the reference electrode body as far as possible, and prevent that the introduced contaminants ion from sneaking in the electrode body, and added the filler that water absorption is strong and be easy to conduct electricity at ceramic pellicle, electrode body and extraneous soil are separated.
The utility model compared with prior art, reasonable in design, reversibility of electrode are good, are difficult for polarization, good stability, reappearance is good, preparation, convenient maintenance, the life-span can reach more than 10 years. Bury the test examination by cathodic protection station scenes such as capital in office line, the big line of iron, eastern yellow line and middle Lip river lines, its effect is excellent.
Claims (3)
1, a kind of long-life buried copper copper sulphate reference electrode that is used for the electrochemical field such as cathodic protection of buried pipeline, cable and metal structures; it is characterized in that: this electrode is by the ceramic pot of manufacturing with ceramic semipermeable membrane material (1), interior dress helical form copper wire (2) and copper sulfate crystal (3); airtight and watertight padding (4) is equipped with in the upper end of sealed disc (5), and cable (7) joins by hole in the middle of the seal cover (6) and helical form copper wire (2) and constitutes.
2, a kind of long-life buried copper copper sulphate reference electrode according to claim 1, it is characterized in that: helical form copper wire (2) and copper sulfate crystal (3) are to be sealed in the ceramic pot (1) with epoxy putty airtight and watertight padding (4), make it to form solid-state structure.
