One end of the solenoid valve 4 is connected to a water inlet pipe 5, and the other end of the solenoid valve 4 is connected to a water outlet pipe 6. One side of the intelligent single light column measuring and controlling instrument 1 is connected to a measuring wire 7, and the other end of the measuring wire 7 is connected to a water level probe 8. The water level probe 8 is arranged inside the mud tank 9;

[0024] The top of the inner wall of the mud tank 9 is connected to a steel pipe 10. The top of the steel pipe 10 is connected to a mounting plate 11. The bottom surface of the mounting plate 11 is connected through a screw 12. The opening of the mud tank 9 is connected to a positioning plate 13, and a rubber ring 14 is embedded in the inner wall of the positioning plate 13.

[0025] Preferably: The screw 12 passes through the mounting plate 11 and is threadedly connected to the inner wall of the mud tank 9. The water level probe 8 passes through the steel pipe 10 and is placed inside the steel pipe 10.

[0026] During specific use, the mud contacted by the lower part of the steel pipe 10 is less affected by the impact and the mud tank 9. At the same time, the fixed steel pipe 10 isolates most of the surge pressure caused by the flow of drilling fluid, greatly reducing the measurement error caused by the surge pressure.

[0027] Preferably, the steel pipe 10 is provided with water inlet holes on the water flow reverse surface, and the water inlet holes are evenly distributed on the reverse surface of the steel pipe 10.

[0028] During specific use, by providing the water inlet holes, it is ensured that the liquid level inside the steel pipe 10 is flush with the liquid level inside the mud tank 9.

[0029] Preferably, a clamping box 15 is connected to the surface of the mud tank 9. One end of the clamping box 15 is threadedly connected with a threaded rod 16, and the other end of the threaded rod 16 is connected with a clamping plate 17.

[0030] During specific use, by moving the clamping plate 17 closer to and clamping the measuring wire 7, the stability of the water level probe 8 is improved, ensuring the accuracy of the measured data.

[0031] Preferably, two linkage plates 18 are connected to both sides of the clamping plate 17. One side of the linkage plate 18 is connected with a guide rod 19, and a limiting plate 20 is installed inside the clamping box 15.

[0032] During specific use, by sliding the guide rod 19 along the limiting plate 20, the stability of the movement of the clamping plate 17 is ensured.

[0033] Preferably, the guide rod 19 and the limiting plate 20 form a sliding connection structure, and the clamping box 15 is a structure with half hollow and half solid.

[0034] During specific use, by adopting the clamping box 15 with a half hollow and half solid structure, it is convenient to cooperate with the clamping plate 17 to ensure the limit fixation of the measuring wire 7.

[0035] Working principle during the specific use of the utility model: Through multiple observations of the drilling process and discussions, it is found that the use of the U-shaped tube principle can greatly reduce the liquid level fluctuation. A steel pipe 10 is fixed to the mud tank 9. During specific use, the mounting plate 11 at the top of the steel pipe 10 is fixed by screws 12. Then, the water level probe 8 is placed into the steel pipe 10. Meanwhile, a water inlet hole is opened on the reverse water flow side of the steel pipe 10 to facilitate the accuracy of the liquid level. The liquid level height in the steel pipe 10 is flush with the liquid level height of the mud tank 9. The mud contacted by the lower part of the steel pipe 10 is less affected by the impact and the mud tank 9. At the same time, the fixed steel pipe 10 isolates most of the surge pressure caused by the flow of the drilling fluid, greatly reducing the measurement error caused by the surge pressure. The accurate liquid level height data provides great convenience for the actual judgment of the drilling fluid consumption and also improves the early warning ability of leakage. In addition, rotate the threaded rod 16 at one end of the rotary clamping box 15 to drive the clamping plate 17 closer to the measurement wire 7. Meanwhile, the guide rod 19 on one side of the linkage plate 18 slides along the limit plate 20, making the clamping plate 17 in close contact with the measurement wire 7 and the clamping box 15, ensuring that the water level probe 8 does not slide during detection and further improving the measurement accuracy.
