[0031] Working principle of the utility model: The top end of the top plate 201 is fixed to the bottom of the drill pipe by bolts.

The hydrogeological detector mechanism 1 extends into the borehole along with the drill pipe. The universal wheels 301 roll along the inner wall of the borehole to reduce the wear between the hydrogeological detector mechanism 1 and the borehole. At the same time, the shock-absorbing spring 304 and the damper 303 cooperate to shock-absorb the connecting rod 302 and reduce the impact on the hydrogeological detector mechanism 1. When the hydrogeological detector mechanism 1 extends to the bottom of the borehole, the pressing block 308 contacts the bottom of the borehole, causing the pressing block 308 to move upward along the installation groove 306 to contact the touch switch 305, so that the touch switch 305 emits a wireless signal to remind the operator that the hydrogeological detector mechanism 1 has reached the bottom. The hydrogeological detector mechanism 1 starts to emit nuclear magnetic resonance for detection. After the detection is completed, the hydrogeological detector mechanism 1 is removed from the borehole, and the transmission rod 202 is rotated in the reverse direction to move the fixing pin 203 out of the fixing hole 103, and the hydrogeological detector mechanism 1 can be removed.
