[0022] 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.

[0023] Please see Figures 1-5 As shown, the purpose of this embodiment is to provide a cathodic protection test pile, including a pile body 1. The pile body 1 includes at least an insulating terminal block 2 and a data acquisition device 3. The insulating terminal block 2 is fixedly installed in the middle of the inside of the pile body 1. The data acquisition device 3 is fixedly installed directly above the insulating terminal block 2. A waterproof chamber 5 is provided directly below the insulating terminal block 2. A solar panel 4 is fixedly installed on the top of the pile body 1, and the solar panel 4 can be rotated and adjusted along the pile body 1. A retaining wall 6 is slidably installed on the outer wall of the pile body 1. The retaining wall 6 is used to improve the stability of the pile body 1.

[0024] The pile body 1 is a rectangular tubular structure. The top of the pile body 1 has a rotating groove 16, and the bottom of the pile body 1 is a cavity, which facilitates the placement of the test piece 7 into the soil. The pipe is electrically connected to the insulating terminal block 2 via a cable.

[0025] The bottom of the rotating groove 16 is a cross-shaped groove, and the middle and upper parts of the rotating groove 16 are cylindrical. The size of the middle part of the rotating groove 16 is larger than the size of the upper part of the rotating groove 16, so that the solar panel 4 can rotate and can restrict the solar panel 4 from being pulled out of the rotating groove 16. The solar panel 4 can rotate after being pulled out to a certain extent. When the solar panel 4 is pressed down, the solar panel 4 cannot rotate and the seal between the solar panel 4 and the pile body 1 is maintained.

[0026] The upper interface of the insulating terminal block 2 is electrically connected to the data acquisition instrument 3 and the solar panel 4 via cables, and the lower interface of the insulating terminal block 2 is electrically connected to several test pieces 7 via cables, so that the wiring ports are evenly distributed to prevent messy cable wiring of the insulating terminal block 2.

[0027] The data acquisition instrument 3 is fixedly installed inside the data acquisition chamber 8. The data acquisition instrument 3 is used to acquire cathodic protection potential and current data and save and upload them to the data acquisition terminal, which can make remote transmission more convenient.

[0028] The solar panel 4 has a rotating shaft 14 at its bottom, and a rectangular protrusion 15 at the bottom of the rotating shaft 14. Specifically, when it is necessary to rotate the solar panel 4, the solar panel 4 must first be lifted upwards, and the rectangular protrusion 15 will disengage from the cross-shaped groove. At this time, the solar panel 4 can be rotated. The solar panel 4 rotates in the rotating groove 16 through the rotating shaft 14. After rotating 90 degrees, the solar panel 4 is released, and then the solar panel 4 is re-clamped into the cross-shaped groove, thereby realizing the rotational adjustment of the orientation of the solar panel 4. The rotating shaft 14 is rotatably installed in the rotating groove 16. Adjusting the direction of the rectangular protrusion 15 in the cross-shaped groove can adjust the light-gathering effect of the solar panel 4 to adapt to different environments.

[0029] The waterproof chamber 5 uses silicone as a waterproof material at the connection. Several cable holes 9 are provided on both the upper and lower inner walls of the waterproof chamber 5. Each cable hole 9 is equipped with a sealing ring 10. Several drainage holes 17 are provided on the side wall of the waterproof chamber 5 near the bottom. The waterproof material, sealing rings and drainage holes 17 ensure good waterproof effect of the waterproof chamber 5 and prevent damage to the instrument due to water seepage.

[0030] The retaining ring 6 includes a retaining ring 11 and several support rods 13. The retaining ring 11 is slidably installed on the outer wall of the pile body 1, and the side wall of the retaining ring 11 is provided with screw holes 12, and bolts are installed in the internal threads of the screw holes 12. The support rods 13 are rotatably installed on both sides of the retaining ring 11 by pins. Specifically, a rotating groove is provided at the center of the side wall of the support rod 13, and the support rod 13 is rotatably installed in the rotating groove. One end of the support rod 13 is fixedly inserted into the soil and works with the retaining ring 6 to support the pile body 1, thereby improving the stability of the pile body 1. The retaining ring 6 can slide and adjust its position on the pile body 1, and the support rods 13 can be rotated to different angles by pins to facilitate support for the pile body 1 in different environments.

[0031] In practical use, this utility model involves excavating a suitable foundation pit according to the size and design requirements of the pile body 1, ensuring that the depth and width of the foundation pit meet the installation requirements of the pile body 1, fixing the pile body 1 to the foundation using bolts, welding or other fixing methods, sliding the retaining wall 6 to a suitable position, tightening the bolts on the retaining wall 11 to fix the position of the retaining wall 6 on the pile body 1, and inserting one end of the support rod 13 into the soil for fixation; and when it is necessary to rotate the solar panel 4, lifting the solar panel 4 upward and rotating the solar panel 4, after rotating it 90 degrees, releasing the solar panel 4, and re-clamping the solar panel 4 into the cross-shaped groove, thereby realizing the rotational adjustment of the orientation of the solar panel 4.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
