Cathodic protection monitoring probe, cathodic protection monitoring probe monitoring system, and manufacturing method and monitoring method thereof

The invention discloses a cathodic protection monitoring probe, a cathodic protection monitoring probe monitoring system, and a manufacturing method and a monitoring method thereof. The probe main body is integrally cylindrical; the probe core is integrally cylindrical and is provided with a hollow blind hole; the hollow hole is a probe core cavity; the upper part of the probe core is provided with an electrode threaded hole which passes through the cylindrical wall of the probe core and is communicated with the probe core cavity; the probe core cavity is provided with a reference electrode; and a fixing layer is arranged between the reference electrode and the cylindrical wall of the probe core so as to fix the reference electrode in the probe core. The cathodic protection monitoring probe has the advantages of scientific design, reasonable structure, reliable performance, wide application range, high stability, strong polarization resistance, and stable quality, and is used for pipeline transportation of various fluid materials such as crude oil, natural gas, running water, urban liquefied gas and the like in the fields such as highways, railways, water transportation, aviation, agriculture and industry and the like.
