In the downward moving process of the water level sensor 14, the water draining pump 17 may be started to timely drain the cooled water in the spiral water pipe 4 below the vertical guiding pipe to the water draining pipe 20, so as to reduce the temperature difference of the water to be measured in the vertical guiding pipe at different positions.
Finally, finishing work after the measurement is finished: (1) the servo motor 36 is reversely started, and the servo motor 36 works to drive the hollow winding shaft 37 to rotate, so that the cable 15 is tightened, and the water level sensor 14 is pulled up to reset; (2) the water suction pump 8 is turned off, the water discharge pump 17 is started or continuously operated until the water in the two spiral water pipes 4 is completely discharged, and then the water discharge pump 17 is turned off; (3) the screw 24 is reversely rotated, so that the two arc clamping plates 28 do separate movement, and the vertical guide tube is released; (4) firstly, the upper limit guide pipe 2 is rotationally disassembled, after the two limit guide pipes 2 are separated, the upper and lower adjacent quick connectors 5 are disconnected, and then the lower limit guide pipe 2 is taken out; (5) pushing the movable support 1 to reset the measuring instrument.
In summary, compared with the conventional water level detection devices such as the water level sensor 14 and the steel ruler water level gauge, the water level measuring device according to the embodiment of the invention improves the situation that the detection device is easily affected by the environment and the temperature in the drill hole, thereby enabling the measurement data to be more accurate.
