Water level probe for water injection test

The utility model provides a water level probe for water injection test, which belongs to the technical field of water injection test and comprises a probe body, a shielding cylinder and an air passage, the shielding cylinder is arranged on the probe body and is used for shielding the sprayed water falling onto the probe body; the air channel is communicated with the interior of the shielding cylinder, and when the probe body is inserted into the deep hole and below the water surface where water is injected, gas in the shielding cylinder is discharged through the air channel; and when the shielding cylinder is pulled out from the position below the water surface where water is injected in the deep hole, gas outside the shielding cylinder is sucked into the shielding cylinder through the gas channel. The water level probe for the water injection test has the technical effects that the water level probe is not sprayed with water, the shielding effect of the shielding cylinder is good, and the water level detect
