Description

Technical Field

[0001] The present invention relates to the technical field of borehole water level measurement, and specifically to a borehole water level measurement device for geological exploration. Background Technique

[0002] Geological exploration is a systematic and in-depth investigation activity that uses geological theories, methods, and technologies to study geological phenomena on the surface and underground. Its core purpose is to reveal the internal structure of the earth and the distribution law of resources, providing a scientific basis for resource development, engineering construction, and disaster prevention and control.

[0003] Borehole water level measurement refers to the process of quantitatively measuring the underground water level through professional equipment and technical means. The depth of the underground water level is directly read through a water level gauge or a water level indicator, which helps to evaluate the impact of the change in the underground water level on the project. Combining sensors such as conductivity and temperature, the chemical properties of the water body are monitored in real time to assist in judging the water quality condition. In addition, by monitoring the water level change, the risk of mine water inrush and the stability of the aquifer are evaluated, providing data support for water control work. This measurement plays a key role in engineering fields such as oil, natural gas, and mines.

[0004] During the process of quantitatively measuring the underground water level, the following problems exist: 1. Since there may be some debris and small stones remaining in the underground water, it will affect the use of the probe, resulting in measurement accuracy errors. 2.

Inside the protective shell 401, a lifting device 7, an impurity filtering device 6, and a water level measuring device 5 are arranged. The lifting device 7, the impurity filtering device 6, the water level measuring device 5, and the protective shell 401 form a cleaning chamber 402. A cleaning liquid is arranged in the cleaning chamber 402. One end of the protective shell 401 is provided with a connecting rod 407. The protective shell 401 is fixedly connected to the measuring scale 104 through the connecting rod 407. A scale 403 is arranged on the inner surface of the protective shell 401.

A rubber ring 406 is arranged on the cylindrical surface of the clamping block 405. The rubber ring 406 is used to reduce the impact effect.

[0030] Please refer to Figure 2 and Figure 5 , the impurity filtering device 6 includes a sealing block 601. The sealing block 601 is fixedly connected to the protective shell 401.

The other end of the filter screen 602 is fixedly connected to a sleeve 603. A mounting rod 604 is arranged on the cylindrical surface of the sleeve 603. The mounting rod 604 is fixedly connected to the protective shell 401. The filter screen 602 filters sundries and small stones in the water to avoid the influence of sundries and small stones on water level measurement.

[0031] Please refer to Figure 2 and Figure 4, the water level measuring device 5 includes a water level gauge 502. The water level gauge 502 penetrates through the sealing block 601. One side of the water level gauge 502 is provided with a support plate 501. The support plate 501 is vertically and slidably connected to the protective housing 401. The other end of the support plate 501 is provided with a driving mechanism 3. A connecting block 503 is arranged on the cylindrical surface of the water level gauge 502. The water level gauge 502 is rotationally connected to the lifting device 7 through the connecting block 503. The other end of the water level gauge 502 is provided with a measuring probe 506. The water level gauge 502 is fixedly connected with a connecting column 505. The other end of the connecting column 505 is fixedly connected with a plugging block 504. When the measuring probe 506 enters the cleaning chamber 402, the plugging block 504 enters the sealing block 601 to plug the sealing block 601, preventing the cleaning liquid in the cleaning chamber 402 from flowing out.

[0032] Please refer to Figure 2 and Figure 6 , the lifting device 7 includes a collar 701. The collar 701 is sleeved on the cylindrical surface of the connecting block 503 and is rotationally connected to the connecting block 503. A threaded groove 704 is formed on the cylindrical surface of the collar 701. The collar 701 is threadedly connected to the internal thread 404 through the threaded groove 704. One side of the collar 701 is provided with an annular plate 702. A plurality of gear teeth 703 are arranged on one side of the annular plate 702. The annular plate 702 is meshed with the driving mechanism 3 through the gear teeth 703. The collar 701 drives the threaded groove 704 to rotate. Since the threaded groove 704 is threadedly connected to the internal thread 404, when the threaded groove 704 rotates, the collar 701 moves vertically. The collar 701 drives the water level gauge 502 to lift through the connecting block 503, that is, the water level gauge 502 drives the measuring probe 506 to move into the cleaning chamber 402, and the measuring probe 506 is cleaned by the cleaning liquid in the cleaning chamber 402.

[0033] Please refer to Figure 2 , the driving mechanism 3 includes a motor 301. The motor 301 is fixedly connected to the support plate 501. One end of the motor 301 is provided with a motor shaft 302. The motor shaft 302 penetrates through the support plate 501 and is in rotational contact with the support plate 501. The other end of the motor shaft 302 is provided with a driving gear 303. The driving gear 303 is meshed with the gear teeth 703. The motor 301 controls the rotation of the motor shaft 302. 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.

[0034] The working principle of the present invention is as follows: The device pulls the support frame 201, causing the first guide rod 202 and the second guide rod 203 to move along the guide groove 105. When the first guide rod 202 moves to the top of the guide groove 105, it rotates a certain angle with the second guide rod 203 as the rotation axis, enabling the support frame 201 to form a bracket to support the measuring scale 104. Then, by rotating the grip 102 through the grip 102, the grip 102 lowers the protective shell 401 through the winding drum 103 and the measuring scale 104, thus replacing the traditional method of lowering the water level measuring instrument along the hole wall. The cylindrical surface of the protective shell 401 is provided with a clamping block 405 and a rubber ring 406, which can reduce the impact caused by collisions. 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. The measuring probe 506 is located in the filter screen 602, and the filter screen 602 filters debris and small stones in the water to prevent them from affecting the water level measurement. When the measurement is completed, the motor 301 controls the rotation of the motor shaft 302, and the motor shaft 302 drives the driving gear 303 to rotate. Since the driving gear 303 meshes 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 threaded groove 704 to rotate. Since the threaded groove 704 is threadedly connected to the internal thread 404, the collar 701 moves vertically when the threaded 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 liquid 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, preventing the cleaning liquid in the cleaning chamber 402 from flowing out.
