The utility model discloses a mine exploration
water level measuring device which comprises a rack, a motor is arranged on one side of the rack, an output shaft of the motor is connected with a rotating roller, a ruler belt is wound on the rotating roller, one end of the ruler belt is fixed on the rotating roller, the other end of the ruler belt is connected with a
water level detection head, and the
water level detection head is connected with a water
level sensor. The water level detection head comprises a floating ball liquid level switch and a sampling
barrel; the motor works to drive the rotating roller to rotate, the rotating roller lengthens the ruler belt, when the floating ball liquid level switch makes contact with the liquid level and the floating ball floats under the action of
buoyancy, the floating ball liquid level switch controls the motor to
brake, the scales of the ruler belt are observed at the moment, the descending length of the ruler belt is visually obtained through the scales, and therefore the water level depth is obtained. The water level can be rapidly measured, and long-distance and high-precision measurement can be achieved; the sampling
barrel is located on the lower portion of the floating ball liquid level switch, water
level measurement and
water body sampling are conducted at the same time, and therefore exploration efficiency is improved.
