Description

Technical Field

[0001] The utility model relates to the technical field of polarization probes, in particular to a manganese dioxide polarization probe. Background Art

[0002] In order to avoid corrosion, metal structures often need to be protected by cathodic protection technology. Cathodic protection technology is a type of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes the cathode, thereby inhibiting metal corrosion and avoiding or weakening the occurrence of corrosion. In daily maintenance and inspection, cathodic protection requires the use of a polarization probe to measure the on and off potential. The polarization probe is processed using advanced technology and can effectively eliminate the potential error caused by factors such as soil IR drop and stray current, thereby accurately detecting the protection potential value on the protected structure.

[0003] A polarization probe disclosed in the Chinese utility model patent application disclosure CN218291126U is positioned and installed by a positioning block, and the connecting rod is driven to move by a threaded ring, so that the convex slider drives the limit rod to move. The limit rod enters the interior of the limit groove to facilitate limiting the position. The limit rod leaves the limit groove, which facilitates the removal of the gland and the maintenance and repair of the interior of the polarization probe, thereby achieving the purpose of improving practicality. However, the removal process is relatively cumbersome, and the adjustment ring needs to be rotated to insert the limit rod into or leave the limit groove through the connecting rod, the matching block and the convex slider, thereby having the disadvantages of inconvenience and rapid removal of the gland.

[0007] Optionally, both the upper and lower surfaces of the outer side of the card block are provided with inclined surfaces, and the length of the inclined surface on the upper side of the card block is smaller than the length of the card block inserted into the card slot.

[0011] The utility model provides a manganese dioxide polarization probe, which has the following beneficial effects:

[0012] 1. The manganese dioxide polarization probe has the effect of rapid maintenance inside the probe through the arrangement of the card block, the card slot, the pressure rod, the push block, the third spring and the spring block. During use, when a fault occurs in the polarization probe body or maintenance is required on the polarization probe body, when the pressure cover is opened, the staff presses the annular pressure block downward, and the pressure rod is driven to move downward by the annular pressure block, and the pressure rod drives the push block to move downward in the card slot. Since the inclined surface of the lower surface of the push block close to the card block contacts the inclined surface of the upper surface of the card block, when the push block moves downward, the card block is pushed out of the card slot. After the push block is completely at the bottom, the inclined surface of the upper surface of the card block contacts the corner of the card slot. Since the third spring is in a compressed state, an upward force is generated under the action of the third spring. This force acts on the pressure cover through the spring block, the first sealing gasket and the second sealing gasket. Then, when the card block is partially moved out of the card slot (the inclined surface of the upper surface of the card block contacts the inclined surface of the upper surface of the card block), the card block is pushed out of the card slot. The card block is pressed into the groove under the action of the force provided by the third spring. After the card block is completely entered into the groove, the elastic potential energy of the third spring is completely released, and the pressure cover is ejected from the installation groove, so that the pressure cover can be removed. At this time, the polarization probe body can be maintained. Similarly, during installation, the pressure cover is inserted into the protective cover. During the insertion process, the inclined surface of the lower surface of the card block contacts the corner of the protective cover. By applying a downward force, the card block is squeezed into the groove. When the groove moves to the card slot, the card block is inserted into the card slot under the action of the first spring, and the installation is completed. At the same time, the first sealing gasket and the second sealing gasket are pressed against each other to play a sealing role. The device can quickly remove the pressure cover by pressing the annular pressure block. During installation, the pressure cover only needs to be pressed into the protective cover to be automatically locked, which plays a role of quickly removing the pressure cover, thereby achieving the purpose of facilitating maintenance of the polarization probe body.
