Description

Technical Field

[0001] The utility model relates to the technical field of underground pipeline anti-corrosion, and more particularly to a sacrificial anode installation structure for underground pipelines. Background Art

[0002] The sacrificial anode for buried pipelines is a commonly used cathodic protection method in China. It is used to prevent corrosion of buried metal pipelines. It protects the pipeline from corrosion by connecting a metal with a more negative point (such as magnesium, zinc or aluminum alloy) to the metal pipeline to be protected. The sacrificial anode itself corrodes and welds.

[0003] To prevent corrosion in underground pipelines, sacrificial anodes need to be installed. However, most existing sacrificial anodes are welded directly to the pipelines, making them difficult to replace if damaged. Some sacrificial anodes are bolted to the outer wall of the pipeline. However, due to the long-term damp and cold environment of underground pipelines, these bolts are prone to rust and corrosion, making replacement of new sacrificial anodes impossible. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a sacrificial anode installation structure for underground pipelines, which is convenient for installation and removal of the sacrificial anode and improves the efficiency of sacrificial anode removal.

[0007] To further optimize the technical solution, the clamping mechanism includes a lever hinged in the groove through a rotating shaft, a clamping block extending into the clamping groove on the sacrificial anode mounting block is provided on the outer side of the inner end of the lever, and a second spring for supporting the clamping block is provided between the inner side of the inner end of the lever and the groove.

[0008] To further optimize the technical solution, the outer end of the shift rod extends out of the groove.

[0009] To further optimize the technical solution, a movable plate is provided in the sacrificial anode mounting groove via a plurality of first springs, and the movable plate is in abutment with the sacrificial anode mounting block.

[0010] To further optimize the technical solution, a sponge gasket for supporting the sacrificial anode is provided between the mounting hole of the sacrificial anode mounting block and the sacrificial anode.

[0011] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows.

[0012] The utility model provides a sacrificial anode mounting structure for an underground pipeline, which adopts a sacrificial anode mounting block to install the sacrificial anode in a mounting groove on the outer wall of the pipeline, and realizes the clamping and fixing of the sacrificial anode mounting block through clamping mechanisms on both sides, which can conveniently and quickly realize the installation and removal of the sacrificial anode, thereby improving the efficiency of the installation and removal of the sacrificial anode.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A sacrificial anode installation structure for buried pipelines, combined with Figures 1 to 2 As shown, it includes a pipeline 1 buried underground, with connecting flanges 2 provided at both ends of the pipeline 1, a sacrificial anode mounting groove 3 provided on the outer wall of the pipeline 1 for installing a sacrificial anode 5, a sacrificial anode mounting block 4 provided in the sacrificial anode mounting groove 3, a mounting hole provided inside the sacrificial anode mounting block 4 for placing the sacrificial anode 5, and a sponge gasket 6 provided between the mounting hole of the sacrificial anode mounting block 4 and the sacrificial anode 5 for supporting the sacrificial anode 5.

[0018] A card slot 14 is provided on both sides of the sacrificial anode mounting block 4, and a groove 10 is provided on both side walls of the sacrificial anode mounting groove 3. A card connection mechanism is provided in the groove 10 and extends into the card slot 14 to fix the sacrificial anode mounting block 4 in the sacrificial anode mounting groove 3. Two wires 7 extend from the outside of the sacrificial anode mounting block 4 through the through hole, one end of the wire 7 is connected to the sacrificial anode 5, and the other end of the wire 7 is connected to the contact of the pipeline 1.

[0019] The latching mechanism includes a lever 12 hingedly connected to a groove 10 via a rotating shaft 11. A latching block 15 is provided on the outer side of the inner end of the lever 12. The latching block 15 extends into a latching groove 14 on the sacrificial anode mounting block 4. A second spring 13 is provided between the inner side of the inner end of the lever 12 and the groove 10 to support the latching block 15 so that the latching block 15 extends into the latching groove 14, thereby securing the sacrificial anode mounting block 4. The outer end of the lever 12 extends out of the groove 10. By moving the two levers inward, the inner end of the lever moves outward under the action of the rotating shaft, driving the latching block outward, releasing the latching groove, and allowing the sacrificial anode mounting block to be removed from the sacrificial anode mounting groove.

[0020] A movable plate 8 is provided in the sacrificial anode mounting groove 3 through several first springs 9. The movable plate 8 is in contact with the sacrificial anode mounting block 4. When the sacrificial anode mounting block 4 is fixed in the sacrificial anode mounting groove 3, the sacrificial anode mounting block squeezes the first spring through the movable plate. When the lever is pushed inward to remove the sacrificial anode, when the card block moves outward to release the card slot, the first spring ejects the sacrificial anode mounting block through the movable plate.

[0021] When installing the sacrificial anode, the utility model puts the sacrificial anode into the mounting hole of the sacrificial anode mounting block, and the wire of the sacrificial anode extends from the through hole on the sacrificial anode mounting block. The clamping grooves on both sides of the sacrificial anode mounting block correspond to the levers on both sides of the sacrificial anode mounting groove. When the levers are pushed inward, the sacrificial anode mounting block is pushed inward. When the outer edge of the sacrificial anode mounting block is flush with the pipeline, the levers are released. At this time, the levers push the clamping block into the clamping groove under the action of the second spring, and the sacrificial anode fixing block is fixed in the sacrificial anode mounting hole, thereby realizing the rapid installation of the sacrificial anode.

[0022] When removing the sacrificial anode, the levers on both sides are pushed inward. Under the action of the middle rotating shaft, the inner ends of the levers move outward. When the clamping block moves outward to release the clamping slot, the first spring ejects the sacrificial anode mounting block through the movable plate. The sacrificial anode can be removed by taking it out of the mounting hole of the sacrificial anode mounting block.
