Abstract
The utility model relates to cathode protecting equipment of steel pipelines buried in the ground, which is composed of steel pipelines (6), a clamp (1) and a sacrificial anode (2), wherein the clamp (1) is annular, and the surface of the outer circle of the clamp (1) is provided with three to five screw holes (3) evenly distributed along the circumferential direction. The screw holes (3) are through holes and are screwed with screws (5). The sacrificial anode (2) whose natural potential is lower than the natural potentials of the steel pipelines (6) is in the shape of a sleeve barrel, and the clamp (1) is enchased in an inner cavity of the sacrificial anode (2). The sacrificial anode (2) is provided with two grooves (4) along the axial direction, and the sacrificial anode (2) is divided into two parts by the grooves. The screws (5) contact the outer surfaces of the steel pipelines (6), and the sacrificial anode (2) and the clamp (1) are welded together. The sacrificial anode (2) of the cathode protecting equipment is clamped on the clamp (1) and can be prevented from being stolen, and cathode polarized steel pipelines hardly generate chemical corrosion. The utility model has the advantages of simple structure, low cost and easy popularization and application.
Description
Technical field: the utility model relates to a kind of cathodic protector that is embedded in subterranean steel conduit.
Background technology: at present use in the oil field prevents to be embedded in subterranean steel conduit corrosive sacrificial anode, and it is embedded in the soil of 2 to 3 meters of dark 1.8 meters, lateral extent pipeline usually, and anticorrosion ability is undesirable, and sacrificial anode is stolen easily.
Utility model content:, provide the good and sacrificial anode of a kind of anticorrosion ability to be not easy the cathodic protector of being stolen in order to overcome the defective that the undesirable and sacrificial anode of prior art anticorrosion ability is stolen easily.The utility model is achieved by following scheme, the bracelet-shaped anode of a kind of buried steel pipeline, it is by steel conduit 6, jig 1 and sacrificial anode 2 are formed, jig 1 is circular, have along the circumferential direction equally distributed three to five screw holes 3 on the outer round surface of jig 1, screw hole 3 is a through hole, be combined with screw 5 in the screw hole 3, the sacrificial anode 2 that spontaneous potential is lower than the spontaneous potential of steel conduit 6 is the cover tubular, jig 1 is embedded in the inner chamber of sacrificial anode 2, sacrificial anode 2 has two along axis direction sacrificial anode 2 is divided into two-part groove 4, and screw 5 contacts with the outside surface of steel conduit 6, and sacrificial anode 2 welds together with jig 1.During use, jig 1 cover is stuck on the outside surface of steel conduit 6, tightens screw 5,5 conductions of screw and supporting role are buckled in the outside surface of jig 1 with sacrificial anode 2 and weld together with jig 1.Because the spontaneous potential of sacrificial anode 2 is lower than the spontaneous potential of steel conduit 6, ionogen in the soil is easier with sacrificial anode 2 chemical reaction to take place, the negative charge that reaction produces is given steel conduit 6 by screw 5 conduction, makes steel conduit 6 negative electrodeizations, reaches the protection against corrosion purpose.Sacrificial anode 2 of the present utility model is welded on the jig 1 is not afraid of pilferage, and chemical corrosion takes place cloudy polar steel conduit hardly, the utlity model has advantages simple in structure, with low cost, easy promotion and implementation.
Description of drawings: Fig. 1 is the structural representation of the utility model embodiment one, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the structural representation of embodiment two.
Embodiment one: specify present embodiment below in conjunction with Fig. 1 and Fig. 2, it is by steel conduit 6, two identical jigs 1 and sacrificial anode 2 are formed, jig 1 is circular, have along the circumferential direction equally distributed four screw holes 3 on the outer round surface of jig 1, screw hole 3 is a through hole, be combined with screw 5 in the screw hole 3, the sacrificial anode 2 that spontaneous potential is lower than the spontaneous potential of steel conduit 6 is the cover tubular, jig 1 is embedded in the inner chamber of sacrificial anode 2, sacrificial anode 2 has two along axis direction sacrificial anode 2 is divided into two-part groove 4, screw 5 contacts with the outside surface of steel conduit 6, sacrificial anode 2 welds together with jig 1, and two jigs 1 are separately positioned on two ends of sacrificial anode 2.
Embodiment two: specify present embodiment below in conjunction with Fig. 3.The difference of present embodiment and embodiment one is, the outside surface of steel conduit 6 is coated with corrosion-resistant thermal insulation insulation layer 7, screw 5 passes corrosion-resistant thermal insulation insulation layer 7 and contacts with the outside surface of steel conduit 6, and sacrificial anode 2 has three with sacrificial anode 2 tripartite grooves 4 along axis direction.Other composition is identical with embodiment one with annexation.
