[0002] The cathodic protection corrosion detection, collection and transmission device is an important part of the cathodic protection system. It is mainly used to detect, collect and transmit data on the cathodic protection status of metal structures (such as pipelines, storage tanks, etc.) to ensure the corrosion safety of metal structures. In the process of cathodic protection of pipelines, cathodic protection test piles are often used to perform potential tests on them. According to the patent document with the authorization announcement number CN207793437U and the name "A Cathodic Protection Test Pile Assembly", an insulating protective shell is installed on the outside of the test pile body to protect the conductive test head on the test pile body, while also ensuring that no leakage occurs. A conductive through-hole electrically connected to the conductive test head is provided on the insulating protective shell. When performing a potential test, it is only necessary to insert the test equipment connector into the conductive through-hole, thereby avoiding frequent opening of the insulating protective shell and improving its service life. However, the following defects still exist:

[0003] Although an insulating protective shell is provided to protect the conductive test head, the insulating protective shell is provided with conductive through-holes, so rainwater may easily enter through the conductive through-holes, thereby easily resulting in poor protection effect on the conductive test head.

A protective frame 206 located between the two columns 203 is fixedly installed on the outside of the test pile 1, the insulating protective shell 3 is located inside the protective frame 206, the baffle 205 passes through the protective frame 206, the mounting plate 2010 is located above the protective frame 206, the bottom of the baffle 205 is fixedly connected to a sealing gasket 2012, the bottom of the mounting plate 2010 is fixedly connected to a sealing ring 2011, the sealing ring 2011 is fixed to the outside of the baffle 205, the outside of the test pile 1 is fixedly connected to a waterproof plate 204, the waterproof plate 204 is fixed to the top of the two columns 203, and the waterproof plate 204 is set obliquely;

[0026] When conducting a potential test, first pull the mounting plate 2010 upwards, driving the baffle 205 to rise and be removed from the protective frame 206, and driving the two lifting plates 207 to slide upward along the two columns 203 respectively. At this time, the two reset springs 202 are both stretched, and then you only need to insert the test equipment connector into the conductive through-hole 4. When it is necessary to protect the conductive test head on the test pile 1, release the mounting plate 2010. At this time, the two reset springs 202 reset and drive the two lifting plates 207 to slide downward along the two columns 203 respectively, and drive the mounting plate 2010 to descend so that the baffle 205 is inserted into the protective frame 206, and the sealing gasket 2012 is fitted with the inner bottom wall of the protective frame 206, and the sealing ring 2011 is fitted with the top of the protective frame 206, completing the shielding and sealing of the insulating protective shell 3, and finally preventing rainwater from entering from the conductive through-hole 4, thereby improving the protection effect of the conductive test head.
