Stray current detector for buried steel pipe

The invention relates to the technical field of stray current detection equipment, and discloses a buried steel pipe stray current detector which comprises a box body, a partition plate installed in the box body, a driving plate body installed on the partition plate, a supporting frame fixedly installed in the partition plate, a fixing frame body installed in the partition plate, and a water storage barrel installed on the fixing frame body. The buried steel pipe stray current detector is characterized in that a partition plate is arranged in the shell, a limiting sleeve is arranged in the partition plate, a driving shaft body is arranged in the limiting sleeve, a limiting frame body is fixedly installed at the end of the driving shaft body, and actuating rod frames are symmetrically installed on the limiting frame body. A driving shaft body drives an actuating rod frame to ascend and rotate, so that an end cover of the copper sulfate reference electrode leaves a body, and a clamping sleeve on a lifting panel
