Pipeline potential testing device

The utility model provides a pipeline potential testing device which comprises a walking stick and a potential testing assembly, and the walking stick is of a hollow rod-shaped structure. The potential testing assembly is integrated in a rod body of the walking stick and comprises a universal meter and a copper sulfate electrode electrically connected with the universal meter, the copper sulfate electrode is arranged close to the bottom end of the walking stick, and the testing end of the copper sulfate electrode can automatically stretch out of or retract into the rod body. The pipeline potential testing device is combined with the patrol line walking stick, potential testing is integrated with the walking stick, the number of carried tools is greatly reduced, integrated installation of a universal meter and a copper sulfate electrode is achieved, and the processes of installation and disassembly of positive and negative electrode lines and a line clamp of the universal meter are reduced. 本实用新型提供一种管道电位测试装置，包
