Abstract
The utility model relates to a replaceable deep well anode ground bed which is suitable for protecting the metal objects of a steel tube, a bottom plate of a storage tank, etc. which are buried in the ground or are in contact with the ground. The utility model comprises an anode well body, an anode rod which is arranged in the well body, a cable which is connected with the anode rod and a connecting box which is connected with a constant potential rectifier, wherein the anode well body is composed of a plurality of sleeve tubes which are made of concrete, a plurality of water seepage holes which lead into underground water are distributed on the sleeve tubes and the underground water is used as a conducting medium. The connecting position of the sleeve tubes is provided with a centralizer, and the anode rod which is arranged in the well body is a mixed metal oxide. The integral structure of the utility model has good application property as well as good maintainability. Gas produced is directly escaped in the process of the operation of the ground bed so that the problem that the deep well ground bed is not used because of the phenomenon of gas blockage is effectively avoided, and the deep well anode ground bed is conveniently repaired or replaced. The utility model has the advantages of small size, light weight, high corrosion preventive performance, resources saving and low cost.
Description
Technical field
The utility model relates to changeable deep well anode land bed, and the metal object that is particularly useful for burying ground or contacts with ground is as the electro-chemical protection of steel pipe, storage tank bottom plate etc.
Background technology
Galvanic protection is a kind of relatively rational and effective anticorrosion technique to the metal structures, and it as negative electrode, adopts external power source to provide electronics by anode bodies to the protection object on protected object, to slow down or to eliminate corrosion of metal.Deep well anode land bed as one of chief component of cathodic protection system plays crucial effects to effective operation of total system.At present, using more anode material is graphite anode or high silicon cast-iron anode, but when adopting deep-well as anode groundbed, because the material own wt is bigger, add packing materials such as coke, more than ten anodes successfully will be installed in the dark anode well of tens meters even rice up to a hundred, its difficulty of construction is very high, accidentally will cause accidents such as anode cable fracture, the well that collapses.The coke of inserting is fixed on anode bodies in the deep-well, belongs to disposable engineering, when anode material runs out of or is in operation when ging wrong, can't change and safeguard that whole anode system is also just discarded.In addition, in the operational process of anode well, because reasons such as the fracture of cable, the damage at cable splice place, anodic ununiformity dissolving (end effect and neck effect) and gas obstruction, the deep well anode system will works better, and can't repair, can only discard reconstruction, cause the waste of resource.
Summary of the invention
In view of the problem that prior art exists, it is little that the purpose of this utility model provides a kind of volume, in light weight, rational in infrastructure, easy construction, and operating performance is good, and what be convenient to keep in repair is changeable deep well anode land bed.
The utility model is changeable deep well anode land bed, it comprises segmented anodes well body, it comprises the anode well body, be located at the intravital anode bar of well, the cable that connects anode bar, the terminal box that is connected with potentiostat, described anode well body is that a plurality of sleeve pipes made from concrete constitute, being furnished with on the sleeve pipe and feeding phreatic some infiltrations hole, is conducting medium with underground water; Sleeve pipe and sleeve pipe junction are provided with centralizer, and being located at the intravital anode bar of well is mixed metal oxide.The described mixed metal oxide of making anode bar is matrix with the copper pipe, and matrix surface plates with layer of titanium metal, the outer oxide conducting layer that is coated with again with ruthenium dioxide.
The utility model is changeable deep well anode land bed, is best suited for the metal object that buries ground or contact with ground, as the protection of steel pipe, storage tank bottom plate etc.Employing is furnished with the concrete sleeve in some holes as deep well anode land bed protective tube; and metal oxide materials little, in light weight with volume but the Corrosion Protection excellence is an anode; with underground water is conducting medium; but one-piece construction had both had good application property; has good maintainability again; the gas that groundbed produces in operational process directly benefit goes out, and has avoided because the problem that the stifled phenomenon of gas causes deepwell ground bed to use.Anode material separates with the well body, in operational process in case occur that anode material exhausts or during some other problem, can keep original anode well, just anode is taken out, repair or replace, and do not need to dig a well again, saved resource greatly, reduced cost, tool is practicality widely.
Description of drawings
Fig. 1 is the changeable deep well anode land bed structure iron of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1-anode well body, 2-anode bar, 3-water, 4-cable, 5-terminal box, 6-centralizer.
Embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The utility model is changeable deep well anode land bed, it is mainly by anode well body 1, be located at the anode bar 2 in the well body 1, the cable 4 that connects anode bar, the terminal box 5 that is connected with potentiostat is formed, this anode well body 1 is made of a plurality of sleeve pipes made from concrete, the some infiltrations of cloth hole on each sleeve pipe, so that feeding with water is conducting medium underground water 3, aperture on the sleeve pipe and distributive law are to guarantee that pipeline has certain intensity water can be advisable by interior exosmosis, casing diameter is about about 300mm, and length is advisable about with 1m.Sleeve pipe and sleeve pipe junction are provided with the centralizer made from angle steel 6, and 6 fens three angles of centralizer are symmetrical arranged, and guarantee cooperating between sleeve pipe and the sleeve pipe with this.Be located at the intravital anode bar 3 of well and be mixed metal oxide, mixed metal oxide is matrix with the copper pipe, and the surface is a coating with the metal titanium, the outer oxide conducting layer that is coated with again with ruthenium dioxide.Be drilled into the degree of depth of requirement when anode well after, will be in the concrete sleeve lower going-into-well form protection anode well body 1, with guarantee the borehole wall can not subside and can make well inside and outside keep electrical connectivity (is medium with water).Adopt high-density PVC rope to string the metal oxide anode material, rely on rope and tie cable that anode is suspended in the well, fix, after anode cable gathers, introduce between galvanic protection, be connected on the respective terminal of potentiostat at well head by fixed spacing.
