Description
technical field:
The utility model relates to oilfield exploitation pipeline field, and what be specifically related to is the deep well anode land bed device of a kind of Combined type titanium alloy.
background technology:
Galvanic protection is a kind of relatively rationally effectively anticorrosion technique to metal structures, and it adopts external power source to protection object, to provide electronics by anode bodies using protected object as negative electrode, to slow down or to eliminate corrosion of metal.Deep well anode land bed as one of chief component of cathodic protection system, plays vital effect to effective operation of whole 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 material own wt is larger, add the packing materials such as coke, ten branched anodes successfully will be installed in tens meters of even up to a hundred meters of dark anode well, its difficulty of construction is very high, accidentally will cause anode cable fracture, the accidents such as well of collapsing.The coke of inserting is fixed on anode bodies in deep-well, belongs to disposable engineering, when anode material runs out of or is in operation while ging wrong, cannot change and safeguard, whole anode system is also just discarded.In addition, in the operational process of anode well, fracture, the damage at cable splice place, the reasons such as the ununiformity of anode dissolving (end effect and neck effect) and gas obstruction due to cable, deep well anode system will work, and cannot repair, can only discard reconstruction, cause the waste of resource.
utility model content:
For the not enough the utility model overcoming in background technology provides a kind of Combined type titanium alloy deep well anode land bed device, there is outward current large, long service life, easy for installation, the advantage such as stake resistance is little.
In order to solve the problem existing in background technology, the utility model is by the following technical solutions: the deep well anode land bed device of a kind of Combined type titanium alloy, comprise the steel pipe outside pvc pipe and pvc pipe, it is characterized in that: outside steel pipe upper end, eaves place is provided with U-shaped hanger, steel duct top is provided with upper cover, below is provided with lower end cover, the outer wall of steel pipe upper end is provided with spacing web plate, the inwall of steel pipe lower end is provided with stop nut, the end of pvc pipe is positioned at the outer end of upper cover and lower capping, pvc pipe bottom is provided with the head that is flexible coupling, steel duct is filled friction reducer, titanium anode in steel pipe is fixed on central positioner, titanium anode is provided with cable, cable is through steel pipe, steel duct is provided with central positioner.
Central positioner in described steel pipe is at least provided with three, and central positioner is cross structure.
Described central positioner is welded on steel pipe inner wall.
Described pvc pipe is provided with venting hole, is wound around 100 orders and arranges net on pvc pipe outer wall.
Between described every joint pvc pipe and pvc pipe, by connecting hose, adopt and flexibly connect.
Between described every joint steel pipe and steel pipe, by spacing web plate, be connected with stop nut.
What described titanium anode outgoing cable adopted is acidproof, alkaline-resisting, the pneumoelectric of resistance to halogen cable.
Described titanium anode and the junction of outgoing cable first compress, then weld, and junction is provided with sealing corrosion protective membrane.
The beneficial effects of the utility model are: the utility model is widely used in line of pipes, storage tank urban pipe network, stand field and regional cathodic protection etc.This deep well anode is not limited by landform, minimum on unprotected other underground steel construction impacts.Reasonable in design, the novelty that is skillfully constructed, constructability, maintenance cost is very low, and is easy to large-scale promotion application.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions, the deep well anode land bed device of a kind of Combined type titanium alloy, comprise the steel pipe 4 outside pvc pipe 6 and pvc pipe 6, it is characterized in that: outside steel pipe 4 upper ends, eaves place is provided with U-shaped hanger 2, steel pipe 4 inner upper are provided with upper cover 5, below is provided with lower end cover 11, the outer wall of steel pipe 4 upper ends is provided with spacing web plate 1, the inwall of steel pipe 4 lower ends is provided with stop nut 10, being connected between steel pipe 4 and steel pipe 4 when stop nut 10 and spacing web plate 1 are convenient to install, the constructional difficulties and the insecurity that have overcome former site welding and caused.The end of pvc pipe 6 is positioned at the outer end of upper cover 5 and lower capping 11, and pvc pipe 6 bottoms are provided with and are flexible coupling 12, and being flexible coupling between pvc pipe 6 and pvc pipe 6 while being convenient to install overcome former rigid connection and made that pvc pipe 6 is easily broken to be entered sandy soil and block exhaust.The inner friction reducer 9 of filling of steel pipe 4, the titanium anode 8 in steel pipe 4 is fixed on central positioner 7, and titanium anode 8 is provided with cable 3, and cable 3 is through steel pipe 4, and steel pipe 4 inside are provided with central positioner 7.Central positioner 7 in described steel pipe 4 is at least provided with three, and central positioner 7 is cross structure.Described central positioner 7 is welded on steel pipe 4 inwalls.Described pvc pipe 6 is provided with venting hole, is wound around 100 orders and arranges net on pvc pipe 6 outer walls.What described titanium anode 8 outgoing cables 3 adopted is acidproof, alkaline-resisting, the pneumoelectric of resistance to halogen cable.Cable 3 is inserted after anode, first with Crimping Pliers, compressed, then welding, reusable heat is moulded pipe and is wrapped up the two-layer sealing corrosion insulation of carrying out.Before having overcome, only welding causes easy sealing-off and the larger shortcoming of contact resistance.When assembling titanium anode 8 and pvc pipe 6, adopt central positioner 7 to support.Make titanium anode 8 be positioned at center, pvc pipe 6 is positioned at accurate location, has strengthened the exhaust effect of electric discharge, electroconductibility and the pvc pipe 6 of anode.Overcome former titanium anode 8, pvc pipe 6 positions are uncertain and affect the difficult problem of generating, conduction and exhaust.This deep well anode is not limited by landform, minimum on unprotected other underground steel construction impacts.Reasonable in design, the novelty that is skillfully constructed, constructability, maintenance cost is very low, and is easy to large-scale promotion application.
