Abstract
The utility model relates to a locking type pipeline sacrificial anode. The locking type pipeline sacrificial anode comprises a ground pipeline and a sleeve sacrificial anode, wherein the sleeve sacrificial anode is coaxially and fixedly mounted on the outer edge position of the ground pipeline; one turnbuckle ring is coaxially and fixedly mounted on each of the two ends which are located between the sleeve sacrificial anode and the ground pipeline; the turnbuckle rings are tapered rings with outer turnbuckles at the outer edges; inner turnbuckles are formed in the inner edges of the two ends of the sleeve sacrificial anode; the outer turnbuckles of the turnbuckle rings and the inner turnbuckles of the sleeve sacrificial anode are engaged mutually. As the two ends, between the sleeve and the ground pipeline, of the sacrificial anode are locked by adopting the turnbuckle rings, the degree of positioning and fixation between the sacrificial anode and the ground pipeline is improved, meanwhile the electric connection is also enhanced, convenience is not only brought to installation of the sacrificial anode on the ground pipeline, but the anti-theft effect is also improved efficiently.
Description
Technical field
The utility model belongs to pipeline field, relates to the sacrificial anode of pipeline, especially a kind of locking pipeline sacrificial anode.
Background technique
Along with the carrying out of urban construction, large number of ground pipeline spreads all over the place and is arranged in city, and the subject matter that causes surface duct to lose efficacy is exactly Anticorrosion.At present, the anticorrosion common employing asphalt paint of surface duct, as anticorrosive coat, is aided with the buried sacrificial anode of heap simultaneously and applies current cathodic protection, with the electrochemical corrosion that prevents from being produced after coating layer breakage.At present, pipeline adopts bushing type mode conventionally with sacrificial anode, in use easily occur sacrificial anode sleeve pipe contact with pipeline outer wall bad, locating effect is poor and cause antiseptic effect poor, simultaneously bushing type sacrificial anode mounting point non-adjustable, install inconvenient and affected the quality of pipeline corrosion protection.
In addition, existing bushing type sacrificial anode, owing to there is no locking device, causes stolen phenomenon serious.
By retrieval, not yet find the open source literature relevant to the utility model application.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and be convenient to adjust location, favorable anti-corrosion effect, has the locking pipeline sacrificial anode of anti-theft feature.
The purpose of this utility model is achieved through the following technical solutions:
A kind of locking pipeline sacrificial anode, comprise surface duct and sleeve sacrificial anode, sleeve sacrificial anode is coaxially packed in surface duct outer rim position, it is characterized in that: the two ends between sleeve sacrificial anode and surface duct are all coaxially fixed with a spiral shell clasp, this spiral shell clasp is tapered collar, in outer rim, be shaped with external screw, be shaped with interior spiral shell buckle at the inner edge at sleeve sacrificial anode two ends, the interior spiral shell of the external screw of spiral shell clasp and sleeve sacrificial anode is buckled intermeshing.
And, be also shaped with the clamping platform of radial equipartition at the outer rim position of spiral shell clasp.
Advantage of the present utility model and good effect are:
1, this sacrificial anode adopts tube-in-tube structure, is convenient to after pipe laying, for damageable zone installation of sacrifice anode targetedly, to have improved the antiseptic effect of surface duct.
2, the two ends of this sacrificial anode between sleeve and surface duct adopt spiral shell clasp to carry out the locking at two ends, location and fixation degree between sacrificial anode and surface duct are improved, also strengthened electrical connection simultaneously, not only facilitate the installation of sacrificial anode at surface duct, also effectively improved anti-theft effect.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the A portion structure enlarged diagram of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; The present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.
A kind of locking pipeline sacrificial anode, comprises surface duct 3 and sleeve sacrificial anode 1, and sleeve sacrificial anode is coaxially packed in surface duct outer rim position.
Innovative point of the present utility model is:
Two ends between sleeve sacrificial anode and surface duct are all coaxially fixed with a spiral shell clasp 2, this spiral shell clasp is tapered collar, in outer rim, be shaped with external screw, be shaped with interior spiral shell buckle at the inner edge at sleeve sacrificial anode two ends, the interior spiral shell of the external screw of spiral shell clasp and sleeve sacrificial anode is buckled intermeshing; The clamping platform 4 that is also shaped with radial equipartition at the outer rim position of spiral shell clasp, this clamping platform is used for adopting the spiral shell clasp that screws up with a wrench, spiral shell clasp enter in potler's sacrificial anode and the taper of bronze drum spiral shell clasp and by sleeve sacrificial anode locking and positioning on surface duct.
In the time of operation, can turn spiral shell clasp in both sides simultaneously, realize thus in the location of this position and being fixedly mounted with.
Claims (2)
1. a locking pipeline sacrificial anode, comprise surface duct and sleeve sacrificial anode, sleeve sacrificial anode is coaxially packed in surface duct outer rim position, it is characterized in that: the two ends between sleeve sacrificial anode and surface duct are all coaxially fixed with a spiral shell clasp, this spiral shell clasp is tapered collar, in outer rim, be shaped with external screw, be shaped with interior spiral shell buckle at the inner edge at sleeve sacrificial anode two ends, the interior spiral shell of the external screw of spiral shell clasp and sleeve sacrificial anode is buckled intermeshing.
