Abstract
The utility model discloses an attached anti-corrosion device with a cathode protection function. The attached anti-corrosion device with the cathode protection function comprises an attached device body and a fastener, wherein the attached device body is provided with one or more anode materials internally used as anodes; the anode materials may be zinc or zinc alloys, magnesium or magnesium alloys, zinc magnesium alloys or other anode alloy materials. The attached anti-corrosion device is low in cost, and can be flexibly attached on the area of an original grounding body which is in great need of corrosion prevention to carry out local cathode corrosion prevention, and the service life of a buried steel member, the grounding body or a grounding net can be effectively prolonged by just increasing a little of work.
Description
Technical field
The utility model relates to a kind of attached type erosion protection system with galvanic protection function.
Background technology
China's " power equipment ground connection designing technique rules " regulation, be laid in corrosion than high field grounding device, should take anti-corrosion measures such as hot tinning, pot galvanize according to corrosion property.Because the hot tinning cost is very high, China adopts pot galvanize, but to its anti-corrosion effect, practical experience shows that along with the reduction of coating protection effect, the corrosion of steel is quickened.The measure commonly used of long-term provide protection can be provided, and is galvanic protection---the protected mode of impressed current, sacrificial anode or the two associating.When selecting the galvanic protection mode, do not consider impressed current method usually, because when ground fault takes place, possibly have high potential gradient.Therefore, select for use sacrificial anode to be used for the corrosion prevention of steel ground net.
In practical application, to bury in some steel materials such as buried steel material such as ground steel ground net, shaft tower pull-rod and often have some the most serious corrosion locations, the ground part is gone into to the about 30～80cm of subsurface place at material usually in these positions.Moisture and oxygen freedom are unobstructed in this position soil, and steel material often is in to be done in the wet change procedure, and corrosive medium also causes this position heavy corrosion thereupon corroding steel material repeatedly.In addition, the inhomogeneous place of some local soils also causes the local spot corrosion of steel material serious easily, forms corrosion pit or fracture etc.Corrosion pit or fracture that these local corrosions take place, and then have influence on whole work-ing life of burying the steel grounding device on ground.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of attached type erosion protection system with galvanic protection function, solves etching problem.
For realizing above-mentioned purpose; The concrete scheme of the utility model is: a kind of attached type erosion protection system with galvanic protection function; It comprises attached type device body and fastening piece, and said attached type device body is provided with the anode that one or more zinc or zinc alloy, magnesium or magnesiumalloy, zinc magnesium alloy are processed.
As preferably, anode through compress, paste, welding or riveted joint mode be connected with said attached type device body.
[0007] beneficial effect of the utility model is: cost is low; Can need most attached to original ground connector flexibly and carry out local galvanic protection protection against corrosion on the etch-proof zone; Only increase the work-ing life that minimum ground workload but can effectively prolong buried steel member, ground connector (net), can not reduce requirement the electrical specification of ground net.
Description of drawings
Fig. 1 is the utility model structure iron.
Embodiment:
For the technique means, the creation characteristic that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1, a kind of attached type erosion protection system with galvanic protection function, this attached type erosion protection system with galvanic protection function comprises attached type device body 1, has on the attached type device body 1 as anodic zinc band 2; The attached type device body 1 of present embodiment is the steel plate workpiece.
This making method is: being processed into the attached type device body on the steel plate; Utilization compresses or pastes one or more zinc or zinc alloy, magnesium or magnesiumalloy or other sacrifical anode alloy material; Utilize fastening piece 3 screw screw rods device to be fastened on the base material that needs protection again, promptly accomplish the making and the use of attached type cathodic protector.
A kind of attached type erosion protection system with galvanic protection function, attached type device body 1 is out of shape a little, can have on the attached type device body 1 as anodic zinc band 2 attached on the band steel; The attached type erosion protection system body 1 of present embodiment is the steel plate workpiece.
Record through experiment: it is even to possess protective current; Cost is lower; Can too much not increase the investment level; Can directly need most on the etch-proof zone at original ground connector and construct, only minimum ground of the construction increase workload than existing ground net but can effectively prolong the work-ing life of whole ground net, can not reduce the requirement to the electrical specification of ground net.
Anode material on the attached type device body adopts and compresses, pastes, welding, riveted joint mode connect.Novel attached type ground connector device is for adhering to fastening-type.Anode can use zink rod, also can be straight type, can have many.
The attached type device body adopts and goes up card, following cartoon is crossed fastening piece and surrounded formation.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; The profile of the utility model body part and the quantity of anode material also have various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
