Description

Technical Field

[0001] This utility model relates to the technical field of mine drainage equipment, and in particular to a multi-stage drainage device for mines. Background Technology

[0002] A multi-stage drainage system for mines is a device used to drain various types of groundwater within a mine. This system typically uses pumps to extract and discharge groundwater from the mine shaft. Existing multi-stage drainage systems generally utilize multiple identical pressurizing devices installed inside pipes to pressurize the groundwater drawn in by the pumps under the rotation of turbine fans within a pressurization tank before discharge. However, because the pressurizing devices inside the tank typically have an outlet on one side and an inlet on the other, the pressurized water impacts the tank wall as it passes through, significantly reducing the flow velocity and wasting considerable energy. Therefore, this problem needs to be addressed. Utility Model Content

The connecting cylinder 9 has a spiral groove at one end of its inner wall to facilitate water flow, and a circular groove at the other end of its inner wall. A first turbine fan is installed in the circular groove and is fixed to the connecting shaft 10. Multiple fixed disks 13 are fixed at equal intervals on the inner wall of the connecting cylinder 9. A guide port is provided in the middle of each fixed disk 13, and a second turbine fan is provided on one side of each fixed disk 13. The second turbine fan is fixed to the connecting shaft 10, and a baffle disk 12 is installed on one side of the second turbine fan to facilitate the rotation of the first and second turbine fans by the connecting shaft 10.

[0020] In this utility model, the outer side of the barrier plate 12 is attached to the inner wall of the connecting cylinder 9, and a flange 11 is installed on one side of the barrier plate 12. The flange 11 is fixed to the connecting shaft 10. A shell 5 is sleeved on the outer side of the connecting cylinder 9 to facilitate the stability of the connecting cylinder 9. A water inlet pipe 8 and a drain pipe 7 are fixed to both ends of the connecting cylinder 9, and a rectangular block is fixed to the lower end of the shell 5. The rectangular block is fixed to the base 1. A limiting plate 4 is provided on the outer side of the water inlet pipe 8 and the drain pipe 7 at both ends of the connecting cylinder 9.

[0021] Working principle: When using this utility model, first connect all electrical equipment to the power supply, then tighten the nuts at both ends of the limiting rod 6, and then fix the connecting cylinder 9 by the limiting plate 4. Start the servo motor 3, which drives the connecting shaft 10 to rotate, and then drives the first turbine fan and multiple second turbine fans fixed on the connecting shaft 10 to rotate. At this time, water enters from the water inlet pipe 8, and is then pressurized by the multiple second turbine fans. At this time, the water will flow out from one end of the spiral groove and spray out through the drain pipe 7. At this time, due to the fixation of the limiting plate 4 and the limiting rod 6 at both ends of the connecting cylinder 9, the vibration of the connecting cylinder 9 during operation is avoided. When the drainage is completed, turn off the power. At this time, the servo motor 3 stops rotating, causing the turbine fans connected to the connecting shaft 10 to stop rotating. At this time, the drainage is completed.
