Description
Technical field
The utility model is related to a kind of opening suspension type deep well anode structures.
Background technology
Steel construction in soil, in order to control its corrosion, the corrosion that generally use coating and cathode protection technology are combined
Control program.Impressed current deep well anode cathodic protection system is evenly distributed with its earth-current, and effective protection range is wide;Earth's surface electricity
Field intensity is small, small to other underground steel construction clutter interferences around anode, to ideal protection effect can be obtained by protection pipe network
Fruit, and can avoid the features such as stray electrical current interference in underground aggravates the corrosion of other non-protected underground steel constructions and be used widely.
Traditional deep well anode is that impressed current anode such as high-silicon cast iron, titanium-based Mixed Metal Oxide Coated Titanium Anodes are wrapped up coke or graphite powder etc.
Conductive filler is put into well after outer steel pipe, and by the way that gas-guide tube and cable are led to ground after backfill, that there are anodes is easy for which
Generation vapour lock, discharge capacity is small, service life is short, ground resistance is high, equipment output voltage is high, can not replace, easily to non-protected pipe
Line generates the shortcomings of interference.Anode well once breaks down, and entire cathodic protection system can be caused ineffective, only pacified again
Deep well anode is filled, maintenance cost is high, and maintenance time is long.
Utility model content
The problem of the utility model exists for the above-mentioned prior art makes improvement, i.e., skill to be solved in the utility model
Art problem is to provide a kind of opening suspension type deep well anode structure.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is:A kind of opening suspension type deep well anode knot
Structure, including deep-well are provided with insulating sleeve in the deep-well, and the insulating sleeve lower sides offer several water holes,
Insulating sleeve lower outside wall is arranged with the filter sheath for preventing mud from entering, and is hung with anode under liquid level in the deep-well, described
Anode top is electrically connected by conducting wire with the cathodic protection supply unit of setting on the ground.
Further, the insulating sleeve is PVC casings.
Further, the filter sheath is pure cotton cloth set.
Further, the insulating sleeve bottom lock.
Further, the anode top is additionally provided with the traction rope of suspension anode and conducting wire.
Further, the deep-well depth is 30~50m, a diameter of 20~30cm.
Further, the water hole is arranged at 10~15m of deep-well lower part.
Further, the 15~20cm of insulating sleeve.
Compared with prior art, the utility model has the advantages that:The gas that present apparatus anode generates can pass through
Water freely escapes, and does not need independent gas-guide tube, not will produce vapour lock failure;Anode is installed in water, and ground resistance is small, required
Equipment output voltage it is low, small to the interference of non-protected pipeline, power consumption is small;The discharge capacity of anode is big, is the one of conventional anode
Times or more;It when anode breaks down, need not dig a well again, only need to change anode, maintenance cost is low, and maintenance time is short.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the organigram of the utility model embodiment.
In figure:1- cathodic protection supply units, the undergrounds 2- steel construction, 3- insulating sleeves, 31- water holes, 4- filter sheaths, 5-
Anode, 6- conducting wires, 7- traction ropes.
Specific implementation mode
Embodiment one:As shown in Figure 1, a kind of opening suspension type deep well anode structure, including deep-well, the interior setting of the deep-well
There are insulating sleeve 3, the insulating sleeve lower sides to offer several water holes 31, insulating sleeve lower outside wall is arranged with
The filter sheath 4 for preventing mud from entering, anode 5 is hung in the deep-well under liquid level, the anode top passes through conducting wire 6 and setting
Cathodic protection supply unit 1 on the ground is electrically connected.
In the present embodiment, the insulating sleeve is PVC casings.
In the present embodiment, the filter sheath is pure cotton cloth set.
In the present embodiment, the insulating sleeve bottom lock.
In the present embodiment, the anode top is additionally provided with the traction rope 7 of suspension anode and conducting wire.
In the present embodiment, the deep-well depth is 30~50m, a diameter of 20~30cm.
In the present embodiment, the water hole is arranged at 10~15m of deep-well lower part.
In the present embodiment, the 15~20cm of insulating sleeve.
Suitable position is selected, beats a bite deep-well using well-digging machinery, the deeper well depth theoretically the better, in Practical Project suggestion
It is advisable deeply at 30-50 meters, the PVC plastic pipe of well diameter a diameter of 15-20cm of installation in 30cm or so, well, according to different wells
It is deep, it is punched in lower part 10-15 meters of section of well, the puncture site of pvc pipe is sleeved on pure cotton cloth set, to stop that mud is flowed into from aperture
In well, conducting wire and anode are bundled with traction rope, are put into well, made to clear water by the mud that well-digging is formed in cleaning well
Anode submerges in water.
When cathodic protection current leads to anode by conducting wire from the anode of instrument, covered by water in anode surface, well and PVC
Pore flows into the earth, eventually flows to protected underground steel construction 2, to realize the corrosion control to underground steel construction.
This structure is that anode bodies vertical hanging is put into phreatic water, and is punched by PVC casing parts, by cathodic protection
Electric current enters the earth by the lower part of deep-well.It the advantage is that:The gas that anode generates can freely be escaped by water, need not be single
Only gas-guide tube not will produce vapour lock failure;Anode is installed in water, and ground resistance is small, and required equipment output voltage is low, right
The interference of non-protected pipeline is small, and power consumption is small;The discharge capacity of anode is big, and drainage density is one times of conventional anode or more;Anode
It when breaking down, need not dig a well again, only need to change anode, maintenance cost is low, and maintenance time is short.It is led using traction rope suspension
Line (i.e. cable) and anode make cable be in relaxation shape, are conducive to extend cable service life.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
