Gas pipeline cathode protection pile monitoring system

Abstract

The invention relates to a fuel gas pipeline cathode protection pile monitoring system which comprises a protection pile arranged near a buried fuel gas pipeline, a monitoring module and a communication module are arranged in the protection pile, a sacrificial anode replacement cavity is further arranged near the protection pile, and a replaceable sacrificial anode is arranged in the sacrificial anode replacement cavity. A replacement barrel is arranged in the sacrificial anode replacement cavity, and a cylindrical sacrificial anode is mounted in the replacement barrel; the cylindrical sacrificial anode is adopted, the electrode penetrating hole is formed in the center of the sacrificial anode, the center conductive column is arranged in the electrode penetrating hole in a penetrating mode, the conductive elastic piece which can abut against the inner wall of the electrode penetrating hole is arranged on the side wall of the center conductive column, the sacrificial anode can be vertically moved, and replacement of the sacrificial anode is facilitated; and the plurality of groups of conductive elastic sheets arranged on the central conductive column can enable the conductive connection between the central conductive column and the sacrificial anode to be reliable, so that the problems that the sacrificial anode is inconvenient to replace and unreliable in contact are effectively solved.

Description

technical field [0001] The invention relates to a gas pipeline maintenance technology, in particular to a gas pipeline cathodic protection pile monitoring system. Background technique [0002] In order to prevent the corrosion of buried gas pipelines, cathodic protection piles of gas pipelines are currently used to protect buried gas pipelines. For example, the "Gas Pipeline Cathodic Protection Remote Online Monitoring Pile" disclosed in the Chinese Patent Document No. CN210596270U, ​​the outer sleeve is also slidably provided with an inner sleeve, the upper end of the inner sleeve is open and is provided with a detachable top cover. The bottom of the sleeve is provided with a wire through hole, and the installation board of the top cover is provided with a wireless GPRS detector and a terminal, and a wire clamp can prevent the connection between the wire and the terminal from loosening or breaking. For example, the "Buried Steel Pipe Sacrificial Anode Replacement Device an...
