Description

Technical Field

[0001] The utility model belongs to the technical field of sacrificial anodes, in particular to a pipeline surface-attached sacrificial anode. Background Art

[0002] Currently, one way to protect pipelines is to use sacrificial anodes to protect pipelines. That is, a metal with strong reducing properties is used as the anode and the protected pipeline is used as the cathode. The principle of the primary battery is used to consume and sacrifice the anode metal, thereby protecting the cathode pipeline.

[0003] The existing sacrificial anode plate is directly fixed on the cylindrical structure. When connected to the inside of the pipe, the sacrificial anode plate is difficult to contact the inside of the pipe well, making it difficult for the sacrificial anode plate to work effectively and not provide a good anti-corrosion effect on the pipe. Utility Model Content

[0004] The present invention aims to solve the problems existing in the prior art and proposes the following technical solutions:

[0005] The pipeline surface attached sacrificial anode includes an arc-shaped part, an attachment installed under the arc-shaped part, and a sacrificial anode device placed on the arc-shaped part. The side wall of the arc-shaped part is connected to a limit plate through an elastic mechanism, and the top of the limit plate is connected to a pressure plate through an adjustment mechanism, and the bottom end of the pressure plate abuts against the sacrificial anode device.

[0006] Under the action of the arc-shaped part, it is installed on the inner wall of the pipe in conjunction with the attachment. At this time, it is coordinated with the limiting mechanism to drive the sacrificial anode device to be installed on the inside of the pipe, completing the stable installation efficiency of the sacrificial anode device on the inside of the pipe, thereby ensuring a good anti-corrosion effect on the pipeline.

[0007] As a preferred embodiment of the above technical solution, the elastic mechanism includes an inner groove opened in the arc-shaped part, and sliding rails are symmetrically opened in the inner groove, and sliders are slidably connected in the sliding rails. The sliders are all installed on the outer wall of the movable rod. The inner walls of the two groups of movable rods are connected by elastic parts, and the outer side of the movable rod is connected to the limit plate.

[0008] Under the action of the elastic reaction force of the elastic member, the two groups of movable rods are driven to retract in the inner groove, completing the initial limiting effect of the limiting plate on the sacrificial anode device from the side wall.

[0009] As a preferred embodiment of the above technical solution, the adjustment mechanism includes a threaded rod threadedly connected to the limit plate, the top end of the threaded rod is connected to the handle, and the bottom end of the threaded rod is installed on the pressure plate.

[0010] Under the action of the threaded connection between the threaded rod and the limiting plate, the driving pressure plate is adjusted according to the width of the sacrificial anode device, so that the driving pressure plate can further limit the sacrificial anode device from the longitudinal direction.

[0011] As a preferred embodiment of the above technical solution, a soft pad is glued to the bottom of the pressure plate, and the bottom of the soft pad abuts on the sacrificial anode device. A protective pad is glued to the inner wall of the limiting plate, and the protective pad abuts on the outer wall of the sacrificial anode device.

[0012] Under the protective effect of the soft pad and the protective pad, the outer wall of the sacrificial anode device is protected to avoid direct contact with the pressure plate and the limit plate to cause wear.

[0013] The beneficial effects of the utility model are:

[0014] In this application, under the action of the arc-shaped member, it is installed and attached to the inner wall of the pipe in conjunction with the attachment. At this time, it is cooperated with the limiting mechanism to drive the sacrificial anode device to be installed on the inside of the pipe, thereby completing the stable efficiency of the installation of the sacrificial anode device on the inside of the pipe, thereby ensuring a good anti-corrosion effect on the pipe.
