AI Technical Summary

Technical Problem

Existing electrode fixing devices are unstable in complex geological environments and are easily affected by external environmental interference, which affects the accuracy and reliability of signal reception.

Method used

The design employs a multi-directional three-dimensional fixing structure, including an upper fixing plate, a lower fixing plate, a movable groove, a plug pin, and a limiting cap. The plug pin can swing radially 15°-30° within the movable groove, and its center of gravity is tilted in a different direction from that of the lower fixing plate. Combined with the limiting cap, it prevents the electrode from falling off, thus forming a three-dimensional limiting for the electrode.

Benefits of technology

This technology enables the electrodes to be stably fixed in complex geological environments, improving the reliability and continuity of signal reception, reducing external interference, and ensuring efficient signal transmission.
