Seawater is a kind of corrosive medium of harshness, and metal is easy to generate corrosion, and the dissolution in seawater in the seawater
The chemical factors such as oxygen, salt content, conductivity, pH value, the sea in the physical factors such as temperature, pressure, the flow velocity of seawater and seawater
The biological factors such as biology, microorganism can all have an impact metal erosion.Metallic structures in the seawater for example bridge, platform,
Ship, Coastal Power Plant and salt water cooling system of nuclear power station etc., if not taking effective safeguard procedures, in short several years
It will be damaged or fail because of corrosion, therefore the corrosion and protection in briny environment is highly important technology.For shore
Extra large power plant and nuclear power station generally use coating and cathodic protection joint preserving method to the steel knot in circulating water cooling system
Structure object carries out Combined Protection, prevents the generation of corrosion or mitigates corrosion.
Cathodic protection is exactly so that protected object surface is generated cathode pole by passing to enough DC currents to protected object
Change, reduces or eliminates the difference in Electrode Potential for the various primary batteries for causing protected object to corrode, so that corrosion current is gone to zero, Jin Erda
To the purpose for preventing protected object from corroding.Cathodic protection is divided into sacrificial anode protection (SACP) and impressed current method (ICCP), application
In can select suitable guard method according to medium and by the working condition of protection works.For seawater water pump, large-scale cydariform
The drainages facility such as strainer, condenser generally uses impressed current cathodic protection, in order to adapt to the installation of different structure object, auxiliary
Anode can use plug-in type, inserted, stent-type mounting structure.
Currently used for works such as rotating drum-shaped strainer, grid and guide grooves, in conventional impressed current cathodic protection system
Using stent-type impressed current anode structure (referring to Fig. 1), impressed current anode 1 is connect using bracket 2 with by protection wall 3.Its disadvantage
Be: installation is complicated, costly, and in addition impressed current anode 1 belongs to disposable installation, replaces after being unfavorable for anode damage, is also not easy to
Current check and maintenance.

In equipped with linear anode assemblies around the Cydariform rotary filtering-net, which includes ammeter, tubulose gold
Belong to oxide anode, cable and with hole sleeve, is mutually gone here and there between ammeter and multiple tubular metal oxide anodes by cable
Connection, and be arranged in band hole sleeve, which is located at topmost；The top with hole sleeve and bottom end are revolved with the cydariform respectively
The building body turned around strainer is fixedly connected；Each tubular metal oxide anode position with the hole on hole sleeve tube wall
It is corresponding.
The top with hole sleeve is suspended on the top of building body, the bottom end with hole sleeve pass through fixed bracket with
The building body connection.
It is equipped with cable protecting tube in the outside of the cable, which is fixed on band hole sleeve by multiple fixing cards
Axle center, the fixing card of least significant end fixes bracket with this and connect with the building body, and other parts or whole fixing cards are used
The fixation bracket is connect with the building body.
The band hole sleeve uses pvc pipe.
The invention has the advantages that compared with traditional cathode protection device, have it is easy to operate, detachably, can be online
The advantages that detection.The concatenated ammeter of the equipment can constantly check the operating mode of Anode, using PVC casing with holes
Both anode surface can have been prevented by seawater scouring, extended service life of equipment, and be conducive to the installation and replacement of anode, can have been guaranteed
Protected current potential meets the requirement for anticorrosion of the equipment such as strainer near+250mV (relative to zinc reference electrode, similarly hereinafter).
