Description

Technical Field

[0001] The utility model relates to the technical field of constant potential instruments, in particular to a drawer cabinet type constant potential instrument. Background Art

[0002] As the name suggests, a constant potential instrument is a device that can continuously provide protective current to keep the potential of the protected metal object constant. Its principle is to rectify and regulate the 220V AC power in the room, and then convert it into DC power as cathodic protection current to be transmitted to the protected metal object.

[0003] The constant potential instrument automatically adjusts the output current by real-time monitoring of the cathodic protection power-on potential, forcing the potential of the protected metal object to be stabilized within a reasonable value, thereby achieving the cathodic protection effect. The impressed current cathodic protection range provided by a constant potential instrument can usually cover tens of kilometers of pipelines. At the same time, due to the large output current, it can be used to protect uncoated exposed metals such as grounding grids.

[0004] In the prior art, two sets of constant potentiostats are usually arranged inside the drawer cabinet type constant potentiostat housing. The two sets of constant potentiostats always maintain a working mode of one for backup and one for use, and labels are pasted on the beams on which the constant potentiostats are installed to indicate whether the two sets of constant potentiostats are working or not working. The labels of the prior art are easy to fall off or be damaged on the outside of the beams, and when the two sets of constant potentiostats work alternately, people need to manually replace the two sets of labels, which is troublesome. Utility Model Content

[0009] Furthermore, the right end of the rotating shaft is movably mounted on the second mounting bracket, and the second mounting bracket is fixedly mounted one set at each of the inner hollows of the first beam and the second beam.

[0010] Furthermore, the moving assembly includes a slider, which is slidably installed in a slide groove, the rear side of the slider is pressed and installed on the synchronous belt through the cooperation of a pressure block and a bolt, and the front side of the slider is slidably installed on a moving button.

[0011] Furthermore, two groups of limiting grooves are arranged on the guide rail, and the limiting grooves are symmetrically distributed at the upper and lower ends of the slide groove. Limiting columns are slidably installed in the limiting grooves, and the rear side of the limiting column is fixedly installed on the moving button.

[0013] Furthermore, a spring is fixedly installed inside the matching groove, and a rear end of the spring is fixedly installed on the boss.

[0014] The beneficial effect of the utility model is that after opening the cabinet door and replacing the constant potentiostat in use, the moving button is pulled outwards by hand, at which time the limit column is disengaged from the limit groove, and then the moving button is pulled downward to make the slider slide downward in the slide groove, driving the synchronous belt to slide downward, and then the two sets of synchronous pulleys drive the rotation of the rotating shaft to achieve the synchronous rotation of the two sets of labels by 180°, and the display information of the two sets of labels is replaced.
