[0003] In the long-distance laying of pipelines, pipeline cathodic protection devices are often used. Cathodic protection technology is used to prevent pipeline corrosion. In the prior art, for example, a long-distance pipeline cathodic protection device with patent publication number CN211199411U can greatly improve the protection performance when used, and can drive away rodents, so that the pipeline is in a negative electrode in the loop and is in a reducing environment to prevent corrosion.
