[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a steel pipeline cathodic protection testing pile, comprising a pipeline 1 and a test pile body 5. A housing 2 is installed on the pipeline 1. The end of the housing 2 away from the pipeline 1 is enlarged to form a cylinder 6. A housing cover 3 is provided on the open end of the housing 2. The end of the housing cover 3 facing the cylinder 6 protrudes to form a cylinder cover 7 that covers the opening of the cylinder 6. A sealing part 16 protrudes from the inner side of the housing cover 3 and the cylinder cover 7. The sealing part 16 is inserted into the opening of the housing 2 and the cylinder 6. A fixing hole is provided on the cylinder cover 7, and a sealing bearing 4 is installed in the fixing hole. The test pile body 5 is installed in the inner ring of the sealing bearing 4. One end of the test pile body 5 is inserted into the interior of the cylinder 6 and is threadedly connected to the cylinder 6. A wiring mechanism is installed between the test pile body 5 and the pipeline 1.

[0020] In this embodiment, the wiring mechanism includes a wiring pipe 8, a first conductive block 10, and a second conductive block 9. The end of the housing 2 facing the pipe 1 is provided with a through hole. A first rubber layer 11 is installed on the inner wall of the through hole. The first conductive block 10 passes through the first rubber layer 11 and is welded and fixed to the pipe 1. The second conductive block 9 is installed on the wiring pipe 8. A winding groove 15 is provided on a section of the test pile body 5 located inside the cylinder 6. The wire 12 on the test pile body 5 is coiled in the winding groove 15. The other end of the wire 12 extends into the wiring pipe 8. One of the wires 12 is fixedly connected to the second conductive block 9. In particular, the winding groove 15 provided on the test pile body 5 plays a crucial role in this process. When the test pile body 5 rotates and descends, the wire 12 connected to the test pile body 5 is automatically and orderly wound into the winding groove 15. This design effectively avoids problems such as wire entanglement, excessive pulling, kinking, or scratching with internal components that may be caused by the rotation and descent of the test pile body 5, thereby preventing wire breakage or damage and ensuring the reliability and durability of the line connection.

[0021] In this embodiment, the first conductive block 10 is provided with a slot, one end of the second conductive block 9 is inserted into the slot and electrically connected thereto, the end of the housing 2 away from the opening is provided with a socket, a rubber ring is installed in the socket, the wiring conduit 8 is installed with a vertical pipe opposite the socket, another wire 12 passes through the vertical pipe and is connected to the copper sulfate reference electrode 14, the copper sulfate reference electrode 14 passes through the rubber ring and is inserted into the soil.

[0022] In this embodiment, both the vertical pipe and the wiring pipe 8 are made of rigid insulating plastic material, which avoids electrical conductivity and increases safety.

[0023] In this embodiment, multiple fixing rods 13 are installed between the wiring conduit 8 and the sealing part 16.

[0024] In this embodiment, both the first conductive block 10 and the second conductive block 9 are made of brass to ensure conductivity.

[0025] In this embodiment, a second rubber layer is embedded on the open end face of the shell 2 and the cylinder 6. The second rubber layer is set to abut against the inner side of the shell cover 3 and the cylinder cover 7 to ensure the sealing between the shell cover, the shell and the shell and the cylinder.

[0026] Working principle: During initial installation, the housing 2 is pre-fixed to the pipe 1. The first conductive block 10 passes through the first rubber layer 11 at the bottom of the housing and is welded to the pipe to achieve electrical connection with the pipe. When it is necessary to install or maintain the test pile, the operator aligns the test pile body 5 with the opening of the cylinder 6 and screws it in. Since the test pile body 5 and the cylinder 6 are connected by threads, rotating the test pile body 5 will allow it to descend smoothly into the cylinder 6.

[0027] During the descent of the test pile body 5, the test pile body 5, which is fixed to the cylinder cover 7 by the sealing bearing 4, will drive the entire shell cover 3, cylinder cover 7 and sealing part 16 assembly to move downward together. The sealing part 16 is inserted into the opening of the shell 2 and the cylinder 6 to ensure the sealing of the connection. At the same time, the wiring pipe 8 connected to the sealing part 16 by the fixing rod 13 also moves downward synchronously.

[0028] As the wiring pipe 8 moves downward, the end of the second conductive block 9, which is fixed on the wiring pipe 8, will gradually insert into the slot on the first conductive block 10. When the test pile body 5 is tightened into place, the second conductive block 9 and the first conductive block 10 will achieve a tight insertion fit, thereby establishing an electrical connection path between the test pile body 5 and the pipe 1.

[0029] Meanwhile, the copper sulfate reference electrode 14, which is connected to another wire 12, passes through the vertical pipe on the wiring pipe 8 beforehand. When the wiring pipe 8 moves down, the tip of the copper sulfate reference electrode 14 passes through the rubber ring in the bottom socket of the housing 2 and is pressed into the soil around the pipe, thereby enabling accurate measurement of the pipe's potential to ground.

[0030] When the test post needs to be disassembled for maintenance or replacement, simply rotate the test post body 5 in the reverse direction to unscrew it from the cylinder 6. This process simultaneously lifts the shell cover 3, cylinder cover 7, wiring conduit 8, and second conductive block 9, causing the second conductive block 9 to disengage from the slot of the first conductive block 10, and bringing the copper sulfate reference electrode 14 out of the soil. During the unscrewing process, the wire 12 is smoothly released from the take-up groove 15, avoiding tangling and damage. The entire disconnection process does not require separate operation of the wire, achieving quick and convenient disassembly.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
