Abstract

The invention provides a tidal range zone corrosion potential measuring device and measuring method.The measuring device comprises a data collector and a testing pipe, a first buoy, an electromagnet, a first limiting rod, a second limiting rod and a reference electrode are arranged in the testing pipe, and a first through groove and a second through groove are symmetrically formed in the pipe wall of the testing pipe; a plurality of baffles are evenly distributed in the first through groove and the second through groove, one end of the first buoy is connected with the electromagnet, the other end of the first buoy is connected with the reference electrode, one end of the first limiting rod is a first connecting end, the other end of the first limiting rod is a first free end, and the first connecting end is rotationally connected with the left end of the electromagnet; one end of the second limiting rod is a second connecting end, and the other end is a second free end. The second connecting end is rotationally connected with the right end of the electromagnet. When the electromagnet is powered on, the first free end and the second free end are magnetically attracted to the left end and the right end of the electromagnet respectively, and when the electromagnet is powered off, the first free end extends into the first through groove and is blocked by the baffle, and the second free end extends into the second through groove and is blocked by the baffle. Through cooperation of the first buoy, the electromagnet, the first limiting rod, the second limiting rod and the baffle, the height of the reference electrode can be changed, the reference electrode stops moving when reaching a to-be-tested position, and the reference electrode is triggered to be communicated with the test position to form a conduction loop; the automatic monitoring of the corrosion potentials at different height positions of the measured sample in the tidal range area is realized. By controlling the power-on and power-off states of the electromagnet, automatic potential measurement at different height positions is realized ingeniously according to the fluctuation and ebb conditions of seawater.
