Abstract
The utility model relates to an anti-theft sacrificial anode used for above grade pipe line, which mainly solves the problems of that the exiting sacrificial anode used for above grade pipe line is easy to be stolen and the exiting sacrificial anode used for above grade pipe line has poor antiseptic effect. The anti-theft sacrificial anode used for above grade pipe line is characterized in that: an alloy anode (2) with the cylindrical shape and which is provided with a thread hole (3) is covered on the outside of a pipe line (1), the thread hole (3) is arranged on the wall of the pipe line, and a top wire (4) is arranged in the thread hole (3). The anti-theft sacrificial anode used for above grade pipe line is covered on the pipe line. The anti-theft sacrificial anode used for above grade pipe line is not easy to be stolen, and the anti-theft sacrificial anode used for above grade pipe line has better antiseptic effect.
Description
Technical field:
The utility model relates to the sacrificial anode that the surface duct electrochemical anti-corrosive is used, especially the antitheft sacrificial anode of surface duct.
Background technology:
The anticorrosion general employing coating (as epoxide coal bituminous) of existing buried pipeline is as preservative coat, after the dope layer breakage of pipeline, easily in breakage generation galvanic corrosion, normally utilize buried sacrificial anode of heap or impressed current cathodic protection, the big final-period management of impressed current cathodic protection front-end investment requires high, generally is not used; And a large amount of at present sacrificial anode and tube contacts of concentrating heap to bury are bad, and preservative effect is poor, is easy to stolen simultaneously.
The utility model content:
In order to overcome the deficiency of the easily stolen and preservative effect difference of existing surface duct sacrificial anode, the utility model provides a kind of surface duct antitheft sacrificial anode, the antitheft sacrificial anode of this surface duct is enclosed within on the pipeline, has the advantages that to be difficult for stolen and favorable anti-corrosion effect.
The technical solution of the utility model is: the antitheft sacrificial anode of this surface duct comprises pipeline, and pipeline is with the alloy anode that is threaded the hole on tubular and the wall outward, and threaded hole is built-in with jackscrew.
The material of above-mentioned alloy anode is a magnesium alloy.
The utlity model has following beneficial effect: owing to take the pipeline in the such scheme to be with the alloy anode that is threaded the hole on tubular and the wall outward, alloy anode is whole tubular and is enclosed within on the pipeline, and then played antitheft effect; Threaded hole is built-in with jackscrew, and jackscrew promptly plays the electrical connection effect and plays fixed action again, makes alloy anode and tube contacts good, thereby favorable anti-corrosion effect.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-pipeline among the figure, 2-alloy anode, 3-threaded hole, 4-jackscrew.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the antitheft sacrificial anode of this surface duct comprises pipeline 1, the pipeline 1 outer alloy anode 2 that is threaded hole 3 on tubular and the wall that is with, the material of alloy anode 2 is a magnesium alloy, magnesium alloy has characteristics such as density is little, current potential negative polarization rate is low, the electric weight of unit weight generation is big, alloy anode 2 is whole tubular and is enclosed within on the pipeline 1, and then played antitheft effect; Threaded hole 3 is built-in with jackscrew 4, screws jackscrew 4 during use, and jackscrew 4 promptly plays the electrical connection effect and plays fixed action again, and alloy anode 2 is contacted with pipeline 1, thereby favorable anti-corrosion effect.
Claims (2)
1, the antitheft sacrificial anode of a kind of surface duct comprises pipeline (1), it is characterized in that: pipeline (1) is outer to be with the alloy anode (2) that is threaded hole (3) on tubular and the wall, and threaded hole (3) is built-in with jackscrew (4).
2, the antitheft sacrificial anode of surface duct according to claim 1 is characterized in that: the material of alloy anode (2) is a magnesium alloy.
