Description

[0001] The utility model relates to the technical field of physical exploration, in particular to a connection structure of an electrode and a cable based on high-density electrical exploration. Background Art

[0002] High-density electrical exploration combines electrical profiling and electrical depth sounding. Its principle is the same as that of ordinary resistivity method, except that high-density observation points are set in the observation. It is an array exploration method. When measuring in the field, only all electrodes (dozens to hundreds) need to be placed on the measuring points. Each electrode needs to be electrically connected to the cable. If the connection between the electrode and the cable is unreliable, it is easy to cause data transmission failure, which in turn affects the measurement results.

[0003] The application date is: 2023-05-25, and the application number is: CN202321286630.0. An electrode fixing device for a high-density electrical measurement system is disclosed. By setting a groove in the fixing mechanism, the spring can be easily fixed, so that the spring is connected to the card block, so that the spring provides elasticity, drives the card block to clamp and fix cables of different thicknesses, enhances the fixing effect of the electrode device, and makes it difficult for the cable to be separated from the electrode rod, thereby enhancing the reliability and stability of the electrical measurement data. The electrode fixing device can achieve a reliable connection between the cable and the electrode rod, but there is a problem that: when in use, the cable needs to pass through the card block of the fixing mechanism. Due to the large number of electrode rods, the threading operation is time-consuming and laborious, affecting the measurement efficiency; and if the fixing mechanism is pre-set to the cable upward, the fixing mechanism is not conducive to the winding of the cable, and the fixing mechanism also needs to be fixed on the electrode rod, which also has the problem of time-consuming and laborious operation.

[0004] Based on this, the present application provides a connection structure of an electrode and a cable based on high-density electrical prospecting, which is convenient for fixing the cable on the electrode while ensuring reliable connection between the cable and the motor.
