Electric detectors are commonly used in onshore seismic exploration, while piezoelectric detectors are commonly used in offshore seismic exploration. Eddy current detectors are a new type of detector developed in the 1980s.

When the worm 25 rotates, it cooperates with the worm wheel 26. The worm 25 and the worm wheel 26 are self-locking. When the lead angle of the worm 25 is smaller than the equivalent friction angle between the meshing gear teeth, the mechanism is self-locking and can achieve reverse self-locking, that is, only the worm 25 can drive the worm wheel 26, but the worm wheel 26 cannot drive the worm 25.

A movable rod 29 is fixed to the top of the threaded shaft 28. The movable arm 32 is linked by the movable rod 29 and the connecting plates 35 at both ends, so that the movable arm 32 moves in a circle with the connection of the linkage rod 33 as the axis, and the other end of the movable arm 32 drives the fixed rod 36 to move accordingly. The fixed rod 36 is limited by the limit arm 34 during the activity, so that the fixed rod 36 drives the detector body 37 to move up and down.
