Automatic take-up and pay-off device for geophysical exploration

The invention discloses an automatic take-up and pay-off device for geophysical exploration, and relates to the technical field of geophysical exploration. The wire winding and unwinding device comprises a base, wire fixing mechanisms, a wire winding and unwinding mechanism, an original wire roller and a backup wire roller, the two wire fixing mechanisms which are arranged up and down are installed between a set of first supporting frames, and the wire winding and unwinding mechanism is connected to a set of second supporting frames; i-shaped plates at the two ends of the original wire roller and I-shaped plates at the two ends of the backup wire roller are slidably connected to the third supporting frames on the two sides correspondingly, and the original wire roller is detachably connected with the take-up and pay-off mechanism. During winding and unwinding, once a wire is loosened, the wire can be continuously kept in a tightened state at any time under the action of the wire pressing device in the wire fi
