[0040] A method for using a borehole water level measuring device for hydrogeological exploration comprises the following steps:

[0041] S1. Check whether all parts of the device are complete, including the placement frame 1, the fixing frame 2, the hanging rope 3, the suspension rod 4, the guide cylinder 12, the capacitive sensor 6, the walking mechanism 7, the debris removal component 8, the positioning component 11 and the cylinder 13, etc., to ensure that there is no damage or missing;

[0042] S2. Place the device next to the drill hole to be measured, adjust the position of the placement frame 1, and ensure that the guide cylinder 12 is aligned with the drill hole;

[0043] S3, the lifting plate 14 is driven to move by the cylinder 13, and the lifting plate 14 drives the earth-breaking rod 15 to penetrate into the ground, thereby fixing the device on the ground;

[0044] S4, driving the cleaning component 8 to rotate around the capacitive sensor 6 through the walking mechanism 7, and the scraper 85 on the cleaning component 8 is used to clean the impurities in the drill hole to prevent these impurities from affecting the measurement accuracy of the capacitive sensor 6;

[0045] S5, slowly release the hanging rope 3, so that the capacitive sensor 6 at the bottom of the boom 4 gradually enters the borehole. When the capacitive sensor 6 touches the water surface, it sends a signal, and the release length of the hanging rope 3 at this time is recorded, and the water level depth can be obtained;

[0046] S6. Record the measured water level depth data and organize and analyze them.

[0047] The working principle of the present invention is: the device is moved into the working area, the lifting plate 14 is driven by the cylinder 13 to move, the lifting plate 14 drives the earth-breaking rod 15 to move, so that the earth-breaking rod 15 is driven downward into the ground, which can prevent the device from tipping over during use, the hanging rope 3 is driven by the driving device on the fixed frame 2 to move it, the hanging rope 3 drives the guide rod to move in the through hole 5, and the suspension rod 4 drives the capacitive sensor 6 to move in the drill hole. In this process, the second motor 762 drives the gear 73 in the fixed block 761 to rotate, and the embedded block 763 slides in the embedded groove 764 to prevent the fixed block 761 from falling. The pulley 765 slides in the annular groove 766 to make the fixed block 761 move more smoothly, so that the gear 73 moves under the action of the gear ring 72 outside the pipe sleeve 71, so that the fixed block 761 drives the cleaning frame 81 to move around the capacitive sensor 6.

During the periodic rotation of the cleaning frame 81, the first motor 9 can be used to drive the cleaning frame 81 to rotate itself, so that the impurities on the inner wall of the borehole can be cleaned and dropped. The capacitive sensor 6 is placed in the water or attached to the cleaning rack 81, so that the capacitive sensor 6 can smoothly reach the predetermined position and accurately contact the water surface, reduce repeated operations, improve measurement efficiency, and improve the accuracy of the measurement results. By effectively cleaning up debris, the direct contact between the sensor and the debris can also be reduced, protecting the sensor from damage and extending its service life. After the capacitive sensor 6 is stretched out of the drill hole after the water level detection work is completed, the extension plate 1084 is driven to move by the pull rod 1085, the extension plate 1084 drives the slide plate 1083 to move, and the slide plate 1083 drives the positioning rod 107 to move, so that the positioning rod 107 leaves the connecting block 103. The positioning hole 106 in the capacitive sensor 6 is formed. At this time, the connecting block 103 is no longer fixed to the connecting groove 102 in the driving block 101. Under the action of the supporting block 105 and the supporting groove 104, the cleaning frame 81 can be prevented from falling from the driving block 101. Then, the cleaning frame 81 can be pulled horizontally to be removed from the outside of the capacitive sensor 6, making the subsequent cleaning and maintenance of the cleaning component extremely convenient. This improvement not only improves work efficiency, but also enables the staff to regularly clean and maintain the cleaning component more easily and safely, ensuring the continuous and efficient operation of the measuring device and the accuracy of the measurement results.
