[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figs. 1-3 As shown, a novel cathodic protection polarization probe includes a probe assembly 1, a protection mechanism 2 is provided on the outer periphery of the probe assembly 1, and a sealing mechanism 3 is provided in the middle of the wall shell of the probe assembly 1.

[0021] In this embodiment, the protection mechanism 2 includes a bottom cover 201, multiple sleeves 202, multiple threaded rods 203, an end cover 204, and a drive assembly 205. One end of each sleeve 202 is fixedly connected at equal intervals to the outer periphery of the bottom cover 201. One end of each threaded rod 203 is rotatably connected at equal intervals to the outer periphery of the end cover 204. The other end of each threaded rod 203 is threadedly connected to the inside of the other end of each sleeve 202. One side of the bottom cover 201 is disposed at one end of the probe assembly 1, and one side of the end cover 204 is disposed at the other side of the probe assembly 1. The drive assembly 205 is disposed inside the end cover 204 and is connected to the threaded rods 203. Rubber pads are provided on the bottom cover 201 and the end cover 204 near the probe assembly 1. The drive assembly 205 includes multiple driven gears 2051, a drive gear 2052, a face cover 2053 and a handle 2054. The outer peripheries of the multiple driven gears 2051 are meshed with the outer periphery of the drive gear 2052. The middle part of the drive gear 2052 is rotatably connected to the middle part of the end cover 204. One end of the threaded rod 203 passes through the end cover 204 and is fixedly connected to the middle of the driven gear 2051. The face cover 2053 is located on the side of the end cover 204 away from the probe assembly 1. The handle 2054 is provided in the middle of the drive gear 2052.

[0022] Specifically, the threaded rod 203 is aligned with the sleeve 202. By rotating the handle 2054, the driving gear 2052 is rotated, which in turn drives the threaded rod 203 to rotate through the driven gear 2051. The threaded rod 203 rotates and moves inside the sleeve 202, thereby bringing the bottom cover 201 and the end cover 204 closer together. This fixes the protection mechanism 2 on the outer periphery of the probe assembly 1, thus protecting the probe assembly 1.

[0023] In this embodiment, the sealing mechanism 3 comprises an outer threaded tube 301, two connecting rings 302, two sealing gaskets 303, a rubber ring 304 and an inner threaded cap 305. The outer threaded tube 301 is arranged at the middle of the wall shell of the probe assembly 1. The two connecting rings 302 are threadedly connected at the middle of the outer threaded tube 301 and arranged on the inner and outer sides of the wall shell of the probe assembly 1. The two sealing gaskets 303 are arranged on the outer periphery of the outer threaded tube 301 and between the connecting rings 302 and the wall shell of the probe assembly 1. The rubber ring 304 is arranged on one side of the outer threaded tube 301 away from the probe assembly 1. The inner threaded cap 305 is threadedly connected on the outer periphery of the outer threaded tube 301. The outer periphery of the outer threaded tube 301 is provided with a raw rubber belt, which is arranged between the outer threaded tube 301 and the connecting ring 302.

[0024] Specifically, the outer threaded tube 301 is fixed in the middle of the wall shell of the probe assembly 1 through the connecting ring 302. The gaps between the outer threaded tube 301, the connecting ring 302 and the probe assembly 1 are sealed by the sealing gaskets 303 and the raw rubber belt. Then the cable is passed through the outer threaded tube 301. Then the inner threaded cap 305 is screwed into the outer periphery of the outer threaded tube 301. Thus the rubber ring 304 is squeezed by the inner threaded cap 305 and pressed on the outer periphery of the cable, thereby sealing. If necessary, the raw rubber belt can be wound on the outer periphery of the cable to increase the sealing between the outer threaded tube 301 and the cable, preventing moisture from the outside from entering the inside of the probe assembly 1, thereby protecting the probe assembly 1.

[0025] Working principle:

[0026] The threaded rod 203 is aligned with the sleeve 202. By rotating the handle 2054, the driving gear 2052 is rotated, and then the driven gear 2051 drives the threaded rod 203 to rotate and move inside the sleeve 202, so that the bottom cover 201 and the end cover 204 approach each other, and the protection mechanism 2 is fixed on the outer periphery of the probe assembly 1, thereby protecting the probe assembly 1. The outer threaded tube 301 is fixed in the middle of the wall shell of the probe assembly 1 through the connecting ring 302. The gaps between the outer threaded tube 301, the connecting ring 302 and the probe assembly 1 are sealed by the sealing gaskets 303 and the raw rubber belt. Then the cable is passed through the outer threaded tube 301. Then the inner threaded cap 305 is screwed into the outer periphery of the outer threaded tube 301. Thus the rubber ring 304 is squeezed by the inner threaded cap 305 and pressed on the outer periphery of the cable, thereby sealing. If necessary, the raw rubber belt can be wound on the outer periphery of the cable to increase the sealing between the outer threaded tube 301 and the cable, preventing moisture from the outside from entering the inside of the probe assembly 1, thereby protecting the probe assembly 1.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
