Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of cathodic protection monitoring, and particularly relates to a portable cathodic protection data recorder. BACKGROUND

[0002] The cathodic protection data recorder is an important equipment for cathodic protection monitoring in the field of metal corrosion prevention. It is an instrument capable of densely collecting cathodic protection potential data, can be connected to a test pile terminal board, and is used with a portable copper sulfate reference electrode. It can measure the AC / DC stray current interference on the pipeline, record the AC potential, energized potential and test piece potential data of the buried pipeline. After the collection is completed, the data is connected to a terminal device, and through special software calculation, analysis and drawing, the cathodic protection effect can be evaluated, the interference source can be judged, and the basis for implementing DC stray current management of the pipeline can be provided. It is widely used in the metal structure corrosion protection of petroleum, natural gas and other industries.

[0003] Although the existing cathodic protection data recorder has the characteristics of hand-held portability, in the mobile operation scene, the operator can easily take it to different work sites. However, in actual use, a more prominent problem is that although the data recorder itself is designed to be convenient to hold and carry, the wire harness connected with the test pile cannot be integrated with the device. This means that in addition to carrying the data recorder, the operator also needs to properly store and carry these wire harnesses, which not only increases the complexity of carrying, but also easily causes the wire harness to be lost or damaged, causing many inconveniences to the on-site operation.
