DETAILED DESCRIPTION

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figures 1-6 As shown, a waterproof cathodic protection pile includes a protection pile body 1. A test port 2 is provided on the side of the protection pile body 1. A door 3 is provided outside the test port 2. Electrical components and several test posts 4 are installed inside the test port 2. An annular inner support 5 is fixedly connected to the inner wall of the test port, surrounding the electrical components and several test posts 4. A sealing ring 6 and a sealing plate 7 are arranged sequentially from the inside to the outside on the side of the annular inner support 5 near the door 3. The sealing ring 6 is attached to the surface of the annular inner support 5 with waterproof adhesive, preventing water from entering the interior of the annular inner support 5 through the large gap between the sealing ring 6 and the annular inner support 5. The side of the sealing ring 6 near the sealing plate 7 is provided with... The sealing plate 7 has an annular groove 8 and an annular boss 9 that engages with the annular groove 8 by means of waterproof adhesive. The engaging structure can improve water tightness. Both the sealing ring 6 and the annular boss 9 are rubber strips that expand when exposed to water. After expanding when exposed to water, they can increase the compression between the annular boss 9 and the annular groove 8, further improving water tightness. Each of the four corners inside the annular groove 8 is provided with a screw hole 10. The sealing plate 7 is provided with a connection hole 11 corresponding to the screw hole 10. The connection hole 11 and the screw hole 10 are connected by a screw 12. By tightening the screw 12, it can prevent the annular boss 9 and the annular groove 8 from becoming loose, so as not to affect the water tightness.

[0025] The protective pile body 1 has two symmetrically arranged drainage holes 13 on its side. The bottom of the test port 2 has an arc-shaped protrusion 15. The bottom of the test port 2 has two symmetrically arranged water leakage holes 14 about the arc-shaped protrusion 15, which facilitates water to flow from high to low to the water leakage hole 14 at the lower part of the arc-shaped protrusion 15. The two water leakage holes 14 correspond to and are connected to the two drainage holes 13 respectively. The drainage holes 13 have a slope 16 that slopes from top to bottom from the inside to the outside, which facilitates water to flow out from the drainage holes 13 and prevents water from accumulating in the drainage holes 13.

[0026] Working principle:

[0027] like Figures 1-6 As shown, when the cathodic protection pile is placed in the open air, when water enters the interior of the test port 2 through the gap between the test port 2 and the door 3, the interlocking structure between the annular groove 8 and the annular boss 9 can improve the water tightness. Both the sealing ring 6 and the annular boss 9 are rubber strips that expand when exposed to water. After expanding when exposed to water, they can increase the compression between the annular boss 9 and the annular groove 8, further improving the water tightness and preventing water from entering the interior of the annular inner support 5, so that water cannot damage the test column or electrical components inside the annular inner support.
