[0002] With the widespread application of pipeline engineering, pipeline corrosion protection has become a key technology, especially for underground or underwater pipelines, which are susceptible to electrochemical corrosion during long-term use. Cathodic protection, a widely used and effective corrosion prevention method, connects the protected pipeline to an external DC power supply or electrode material, turning it into a cathode, thereby reducing the pipeline corrosion rate. However, to ensure the long-term stability of the cathodic protection system and pipeline safety, the status of the cathodic protection current and potential must be regularly monitored to determine the protection effect.

[0003] Existing cathodic protection monitoring equipment is usually a fixed installation structure that lacks flexibility and disassembly. Especially in soft soil environments, the stability is poor, which can easily cause equipment displacement or measurement errors. At the same time, the installation and disassembly procedures are complicated, which increases maintenance costs. In addition, the operation design of some monitoring piles is not user-friendly and is not convenient enough during on-site operation. Therefore, there is an urgent need for a pipeline cathodic protection test pile that is easy to install, highly stable, and adaptable to different geological conditions, so as to improve installation efficiency and ensure measurement accuracy. Therefore, in response to the above problems, a pipeline cathodic protection test pile is proposed. Utility Model Content

By integrating a stop block with a stop slot, combined with a spring and a compression pad, this structure allows for quick attachment and removal, simplifying operation and improving efficiency. Its extended plate structure increases the load-bearing area and enhances stability in soft soils.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Refer to the instruction manual Figure 1-4 , a pipeline cathodic protection test pile, comprising a test pile body 1, a test pile stable base 2 is inserted at the bottom end of the test pile body 1, a wire-laying groove 3 is opened inside the test pile stable base 2, the wire-laying groove 3 is connected to the test pile body 1, an auxiliary groove 4 is opened inside the test pile stable base 2, a limiting groove 5 is opened on the outer wall of the bottom end of the test pile body 1, a limiting block 6 is movably set inside the auxiliary groove 4, one end of the limiting block 6 is inserted inside the limiting groove 5, an elastic snare 9 is sleeved on the outer wall of the test pile body 1, an extrusion pad 8 is fixedly connected to the inner wall of the elastic snare 9, and one end of the extrusion pad 8 is inserted inside the limiting groove 5; when the test pile body 1 needs to be tested When the test pile stabilizing base 2 is installed, the test pile stabilizing base 2 can be directly inserted into the test pile body 1. When the limit block 6 inside the auxiliary groove 4 is located at the limit groove 5, the limit block 6 can be driven by the elastic performance of the spring 7 to insert and fix the limit groove 5, thereby achieving the effect of quick installation and fixation. Conversely, the elastic snare 9 is pressed to drive the extrusion pad 8 to squeeze and move the limit block 6. When the limit block 6 is out of the limit groove 5, the test pile stabilizing base 2 and the test pile body 1 can be separated, thereby making it easy to disassemble the test pile body 1 and the test pile stabilizing base 2, thereby improving the efficiency of installing the test pile body 1.

[0020] Then, a spring 7 is provided inside the auxiliary groove 4, one end of the spring 7 is fixedly connected to the limit block 6, and the other end of the spring 7 is fixedly connected to the auxiliary groove 4; through this structure, the spring 7 uses its own elastic performance to drive the limit block 6 to push, thereby ensuring that the limit block 6 is in a position exposed to the outside of the test pile stable base 2 in a normal state.

[0021] Then, there are four groups of auxiliary grooves 4, limit grooves 5, limit blocks 6, springs 7 and extrusion pads 8, and the four groups of extrusion pads 8 are all fixedly connected to the inner wall of the elastic snare 9. Through this structure, to dismantle the test pile stable base 2, it is necessary to press the four groups of extrusion pads 8 at the same time to drive the four groups of limit blocks 6 to disengage from the four groups of limit grooves 5 at the same time before the test pile stable base 2 can be disassembled from the test pile body 1. However, this operation can be carried out by applying pressure at four places to the elastic snare 9.

[0022] Next, the outer walls of the compression pad 8 and the limiting block 6 are both fitted with the inner wall of the limiting groove 5 ; this structure makes the limiting block 6 and the compression pad 8 more stable when moving inside the limiting groove 5 .

[0023] When the jack is in a fixed position, the jack 11 is moved to the left of the jack and the jack is moved to the right of the jack.

[0024] It should be noted that the material of the toggle ball 12 is made of rubber, and the shaft column 13 and the expansion plate 14 are connected by a rotary damper; this structure allows the operator to have a better anti-slip effect when pushing the toggle ball 12. In addition, through the rotational connection relationship between the shaft column 13 and the expansion plate 14, the expansion angle of the expansion plate 14 becomes adjustable.

[0025] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
