Description

Integrated solid-state long-acting reference electrode
Technical field
The utility model relates to a kind of integrated solid-state long-acting reference electrodes, are mainly used for being protected in cathode protection technology Protect the measurement of current potential.
Background technique
When impregnating steel construction progress cathodic protection in the seawater, the reference electrode that will be installed the long-life carries out cathodic protection Potentiometric detection generally can carry out protection potential measurement, such as steel pipe piles at wharf, offshore wind farm steel knot using high purity zinc reference electrode The projects such as structure basis.Disadvantage of the prior art is that mounting structure is complicated and can be only applied in general briny environment, in tide In the very big environment of water slug (such as at Qiantang River estuary locating for Cao'e River Gate, whenever the junior one, 15 big flood tide, Tidewater impact force is very big), electrode and cable are often washed up by the tides damage, and service life is very short, it is therefore desirable to create one kind Reference electrode structure that is novel, can be resistant to the impact of strength tidewater.
Summary of the invention
The purpose of this utility model is just to provide a kind of integrated solid-state long-acting reference electrode, to solve prior art presence Impact the problem of short time damages failure in biggish environment in tidewater.
To achieve the above object, technical solution adopted in the utility model is: a kind of long-acting reference electricity of integration solid-state Reference electrode is drawn from the rear end of nylon seat including the high purity zinc reference electrode ontology being connected in the screw hole of nylon seat front end in pole Cable, which is characterized in that the rear portion of the pure zinc reference electrode ontology and nylon seat are each provided at the steel bushing of a back-end closure Cavity in, the front end of the steel bushing be equipped with plastic cover plate, the front of the pure zinc reference electrode ontology forward extends out this The centre bore of plastic cover plate;Be welded with one end of cathode cable in the inner peripheral surface of the steel bushing, the other end of the cathode cable with And reference electrode cable is drawn from the fairlead of the steel bushing tube rear end;Epoxy filler is full of in the cavity of the steel bushing;? The rear end of the steel bushing is connected with seamless steel pipe.
The utility model has the advantages that: integrated solid-state structure effectively protects reference electrode cable and cathode cable is exempted from It is directly impacted and broken invalid by tidewater, it is ensured that reference electrode measuring device long-term safety reliably uses in the presence of a harsh environment;It adopts With two-core cable, reference electrode and cathodic protection station terminal respectively use a core, reduce material and construction cost;Integrated solid-state structure is existing Field installation simply, conveniently, reduces labor intensity, improves working efficiency.
Detailed description of the invention
Fig. 1 is the utility model overall structure schematic cross-sectional view.
Description of symbols: 1- high purity zinc reference electrode ontology, 2- plastic cover plate, 3- cathode cable solder joint, 4- internal screw thread, 5- nylon seat, 6- epoxy filler, 7- steel bushing, 8- is seamless short steel pipes (are equipped with internal screw thread), and 9- seamless steel pipe (is equipped with external screw thread), 10- reference electrode cable, 11- cathode cable.
Specific embodiment
Referring to Fig. 1, a kind of integrated solid-state long-acting reference electrode of the utility model, including it is connected to 5 front end spiral shell of nylon seat High purity zinc reference electrode ontology 1 in hole draws reference electrode cable 10 from the rear end of nylon seat 5, which is characterized in that described The rear portion of pure zinc reference electrode ontology 1 and nylon seat 5 are each provided in the cavity of steel bushing 7 of a back-end closure, in the steel bushing 7 Front end be equipped with plastic cover plate 2, the front of the pure zinc reference electrode ontology 1 forward extends out the centre bore of the plastic cover plate 2; It is welded with one end of cathode cable 11 in the inner peripheral surface of the steel bushing 7, the other end and the reference electrode electricity of the cathode cable 11 Cable 10 is drawn from the fairlead of 7 rear end of steel bushing;Epoxy filler 6 is full of in the cavity of the steel bushing 7;In the steel bushing 7 rear end is connected with seamless steel pipe 9.
The steel bushing 7 rear end and a short seamless steel pipe 8 front end weld, the rear end of the short seamless steel pipe 8 with The front end of the seamless steel pipe 9 is connected with each other by screw thread.
The utility model by pure zinc reference electrode ontology 1 and reference electrode cable 10, cathode cable 11 be designed to one it is whole Body structure, reference electrode and its cable connector are placed in inside the overall structure being made of steel bushing 7, and cable is using twin-core electricity Cable a, wherein core, as reference electrode cable 10, in addition a core is connected in advance on the inner wall of steel bushing 7 (measures as cathode Terminal), a part of the inside epoxy resins insulation of steel bushing 7, sealing, the head of only pure zinc reference electrode ontology 1 is sudden and violent Dew is in the seawater.Steel bushing 7 need to be only welded on protected steel construction (cathode) when in-site installation, to realize measurement electricity Connection between cable and cathodic protection station.By taking Cao'e River Gate cathodic protection project as an example, the cathodic protection project of Cao'e River Gate, Using conventional long-life high purity zinc reference electrode, design service life is 20 years for original design, after 6 months, reference electricity Breakage occurs for pole cable and cathode cable epidermis, and cable copper wire is exposed in water short-circuit;Cable and reference electrode junction are broken; Nylon jacket deformation on reference electrode falls off, and reference electrode is caused to fail.It was mounted with that the utility model integration solid-state was long later Reference electrode is imitated, has been used 5 years, service condition is good, and not there is a situation where damaged because of tidewater impact, service life can To meet design requirement, while two-core cable is used, saves a cathode cable, reduce material cost;Most of erector Work is completed in workshop, and scene, which only needs for the bracket of seamless steel pipe to be welded on, can be completed reference electricity on protection steel construction The installation of pole, reduces construction cost.Work progress is easy, convenient and safe and reliable.The very good solution puzzlement of proprietor, And in like environment the selection of reference electrode provide a kind of more reliable mode.
