Abstract
Description

[0002] Geological exploration is an important means of revealing the Earth's internal structure and resource distribution patterns, providing a scientific basis for resource development, engineering construction, and disaster prevention. Borehole water level measurement refers to the process of quantitatively measuring groundwater levels using specialized equipment and techniques. Directly reading the groundwater depth using a water level gauge or water level indicator helps assess the impact of groundwater level changes on projects. Combined with sensors such as conductivity and temperature, real-time monitoring of water chemical properties aids in determining water quality. By monitoring water level changes, the risk of mine water inrush and aquifer stability can be assessed, providing data support for flood prevention and control efforts. This measurement plays a key role in engineering fields such as oil, natural gas, and mining.

The water level measuring instrument 502 is fixedly connected to a connecting column 505, and the other end of the connecting column 505 is fixedly connected to a blocking block 504. When the measuring probe 506 enters the cleaning chamber 402, the blocking block 504 enters the sealing block 601 to block the sealing block 601 to prevent the cleaning liquid in the cleaning chamber 402 from being lost.
[0031] See also Figure 2 and Figure 6The lifting device 7 includes a collar 701, which is sleeved on the cylindrical surface of the connecting block 503 and rotatably connected to the connecting block 503.

[0033] The working principle of the present invention is as follows: the device pulls the support frame 201 to move the first guide rod 202 and the second guide rod 203 along the guide groove 105. When the first guide rod 202 moves to the top of the guide groove 105, the second guide rod 203 is rotated at a certain angle with the support frame 201 as the rotation axis, so that the support frame 201 can form a bracket to support the measuring ruler 104. Then the handle 102 is rotated by the handle 102, and the handle 102 lowers the protective shell 401 through the winding drum 103 and the measuring ruler 104, which can replace the traditional water level measuring instrument lowered along the hole wall. The cylindrical surface of the protective shell 401 is provided with a block 405 and a rubber ring 406, which can reduce the impact caused by collision. When the protective shell 401 drives the water level measuring instrument 502 to be lowered into the water, the measuring probe 506 contacts the water to measure the water level, wherein the measuring probe 506 is located in the filter 602, and the filter 602 filters the debris and small stones in the water. To prevent debris and small stones from affecting the water level measurement, when the measurement is completed, the motor 301 controls the motor shaft 302 to rotate, and the motor shaft 302 drives the driving gear 303 to rotate. Since the driving gear 303 is meshed with the gear teeth 703, the driving gear 303 drives the collar 701 to rotate through the gear teeth 703, and the collar 701 drives the thread groove 704 to rotate. Since the thread groove 704 is threadedly connected to the internal thread 404, the collar 701 moves vertically when the thread groove 704 rotates, and the collar 701 drives the water level measuring instrument 502 to rise and fall through the connecting block 503, that is, the water level measuring instrument 502 drives the measuring probe 506 to move into the cleaning chamber 402, and the measuring probe 506 is cleaned by the cleaning fluid in the cleaning chamber 402. When the measuring probe 506 enters the cleaning chamber 402, the blocking block 504 enters the sealing block 601 to block the sealing block 601 to prevent the cleaning fluid in the cleaning chamber 402 from being lost.
