Description of the embodiments

Fig. 1 and fig. 2 are schematic diagrams of front and side structures of a device for monitoring and measuring drilling depth of a seismic exploration seismic source according to an embodiment of the present utility model. The device comprises a reel 1, a hand-held wheel 2 and a singlechip 3, wherein the reel 1 comprises a magnet 4, a lifting rope 5 and a rocker 6; the hand-held wheel 2 comprises a handle 7 and a winding bracket 8; a Hall sensor 10 is arranged on the winding bracket 8; the Hall sensor 10 is connected with the singlechip 3 through a data line 11.

The magnet 4 is in this embodiment fixed to the side of the reel 1 by means of an adhesive backing.

One end of the lifting rope 5 is wound on the reel 1, the other end is tied with the lifting hammer 9, and the lifting rope is tensioned by the gravity action of the lifting hammer 9, so that the lifting rope can be conveniently wound and unwound in drilling.

The rocker 6 is fixedly mounted on the side of the reel 1.

The winding bracket 8 is fixedly arranged on the side surface of the hand-held wheel 2 through a fixing screw 12.
