[0002] The high-density electrical tester is an instrument used in geological exploration and underground resource detection. It is mainly used to measure the resistivity or conductivity of underground rocks and soil, thereby inferring the underground material composition, hydrogeological characteristics, and possible underground resource distribution.

[0003] In the high-density electrical test instruments currently used, the installation and connection of the grounding electrode often rely on a clamping ring, which is used to be sleeved on the end of the grounding rod to complete the grounding operation of the electrode. However, under the influence of external factors such as strong winds or vibrations generated during equipment operation, the loose connection will be more serious, thereby further affecting the accuracy of the test results. At this time, the connection between the clamping ring and the grounding rod is prone to loosening. This looseness will not only affect the working efficiency of the test instrument, but also affect the accuracy of the test results. Utility Model Content

[0024] See also Figure 1 、 Figure 2、 Figure 3 and Figure 4 The utility model provides a technical solution: a special connection device for a grounding electrode of a high-density electrical tester, comprising a wire assembly 1, the wire assembly 1 comprising a multi-core cable 11 and a grounding rod 12, a mounting assembly 2 fixedly connected to the outside of the wire assembly 1, a line protection assembly 3 slidably connected to the top of the wire assembly 1, and a water seepage assembly 4 provided inside the wire assembly 1;

[0025] The mounting assembly 2 includes a spring clip 21. The interior of the spring clip 21 is fixedly connected to the exterior of the grounding rod 12. A buckle 22 is fixedly connected to the exterior of the spring clip 21. A connecting wire 23 is fixedly connected to the exterior of the multi-core cable 11. The end of the connecting wire 23, away from the spring clip 21, is fixedly connected to a connecting ring 24. A mounting base 25 is fixedly connected to the interior of the connecting ring 24. The mounting base 25 has a locking groove 26 formed inside. The buckle 22 slides and engages with the locking groove 26. This grounding electrode connection device for high-density electrical testers includes a cable assembly 1. The cable assembly 1 consists of a multi-core cable 11 and a grounding rod 12. The multi-core cable 11 is responsible for transmitting electrical signals. The grounding rod 12 is inserted into the ground to ensure effective grounding of the current. The mounting assembly 2 ensures that the entire connection device is firmly and reliably fixed to the test point. The spring clip 21 provides a flexible connection method, ensuring that the grounding rod 12 can be securely installed in various geological conditions. The buckle 22 cooperates with the locking groove 26 to achieve a quick and reliable connection. The connecting wire 23 is used to connect other devices or test instruments. It ensures the stability and reliability of signal transmission. The end of the connecting wire 23 away from the spring 21 is fixedly connected to the connecting ring 24. The connecting ring 24 ensures a firm connection between the connecting wire 23 and other components. The inside of the connecting ring 24 is fixedly connected to the mounting base 25. The mounting base 25 is slidably connected to the buckle 22 through the internal snap-fit ​​groove 26. This enables quick assembly and disassembly. It greatly improves the convenience and efficiency of the device. The buckle 22 is slidably connected to the snap-fit ​​groove 26 and snaps into place. This design allows the various components to be connected together quickly and firmly. It ensures stability and safety during the test process;

[0026] The cam 33 is screwed to the cam 35 so that the cam 33 can be tightened and the cam 33 can be tightened to the cam 35.

[0027] Furthermore, the seepage component 4 includes a seepage hole 41, which is opened on the inner wall of the grounding rod 12. A diversion hole 42 is opened inside the grounding rod 12, and the diversion hole 42 is connected to the seepage hole 41. The design of the seepage hole 41 allows external moisture to enter the grounding rod 12 through these holes. This design ensures that the grounding rod 12 can effectively absorb moisture in a dry soil environment and maintain good electrical contact between the grounding rod 12 and the surrounding soil. The diversion hole 42 is connected to the seepage hole 41 to ensure that moisture can be quickly distributed to various parts of the grounding rod 12 after entering the seepage hole. The design of the diversion hole 42 allows the water flow to diffuse evenly inside the grounding rod 12, avoiding the situation where moisture is concentrated in a certain place and causes uneven current distribution, thereby ensuring the working efficiency of the entire grounding device.

[0028] Specifically, when using the present invention: when in use, first the multi-core cable 11 transmits the electrical signal of the test instrument to the grounding rod 12 through the connecting wire 23, ensuring that the current can be effectively conducted to the ground through the grounding rod 12. The multi-core cable 11 and the grounding rod 12 together constitute the line assembly 1, realizing efficient signal transmission and grounding. Then the installation assembly 2 ensures the stable connection of the line assembly 1. The spring piece 21 is fixed to the outside of the grounding rod 12. Its flexibility allows installation under various geological conditions. The outside of the spring piece 21 is connected to the buckle 22, and the buckle 22 is slidably connected to the snap groove 26 in the mounting seat 25. The buckle 22 can be quickly engaged with the snap groove 26, so that the line assembly 1 is firmly fixed on the mounting seat 25. At the same time, the connecting wire 23 firmly connects the cable and other components through its fixed connecting ring 24. The inside of the connecting ring 24 The top of the cable is connected to the mounting base 25, which provides additional stability. Through the sliding connection between the snap groove 26 and the buckle 22, the mounting assembly 2 can be quickly assembled and disassembled, thereby improving the efficiency of use. Next, the line protection assembly 3 provides a sliding adjustment range through the design of the slide column 31. The reel 32 connected to the top of the slide column 31 adjusts the tightness of the cable by tightening the wire 36, reducing the falling pressure of the connecting line 23. The threaded column 33 is connected through the threaded groove 35 to fix the entire protection assembly. The spring 34 provides additional tension so that the reel 32 can pop out of the threaded groove 35 when the pressure is released. Finally, the water seepage assembly 4 ensures that the grounding rod 12 can absorb moisture in dry soil through the water seepage hole 41 and the diversion hole 42. External moisture enters the grounding rod 12 through the water seepage hole 41 and is evenly distributed through the diversion hole 42, ensuring that the grounding rod 12 maintains good electrical contact with the soil.
