Summary: | The utility model discloses a device for judging different medium interface positions in a hole, which comprises a box body, a motor, a wire wheel, a steel wire rope, a fusiform measuring hammer, a meter counting wheel for metering the length below the steel wire rope and an acceleration sensor for sensing the lowering acceleration of the steel wire rope, the motor and the wire wheel are positioned in the box body, and the fusiform measuring hammer is positioned outside the box body. The wire wheel is arranged on the motor, the steel wire rope is wound on the wire wheel and penetrates out of the bottom of the box body, the lower end of the steel wire rope is connected with the fusiform measuring hammer, and the acceleration sensor is arranged on the meter counting wheel. When the measuring hammer freely falls, the acceleration in the same medium is basically unchanged, when the measuring hammer enters another medium every time, the acceleration suddenly changes at the interface, the thickness of the medium ca |
