Abstract
Description
Technical Field
[0001] This utility model relates to the field of downhole water pump technology, specifically to a downhole water pump pumping device. Background Technology
[0002] The primary reason for using underground water pumps is to ensure safety and normal operations in mines. The underground environment is complex, with abundant groundwater. Failure to pump out groundwater promptly can lead to ground subsidence, flooding of tunnels, and impaired mine ventilation, posing safety hazards and potentially threatening miners' lives. Underground water pumps efficiently remove accumulated water from mines, keeping tunnels dry, preventing flooding, and ensuring ventilation and operational safety within the mine.
[0003] Downhole water pumps are prone to clogging due to impurities during operation. This typically occurs when the well water contains a large amount of silt, particulate matter, or other suspended solids. These impurities can accumulate at the pump inlet, leading to reduced flow rate, decreased head, or even complete cessation of operation. Regular cleaning and maintenance of the pump are necessary. Severe clogging can affect the normal operation of the entire pump. Therefore, we propose a downhole water pumping device and corresponding measures to ensure its normal operation. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When using a submersible pump, an interception structure is set at the bottom inlet of the submersible pump to intercept large impurities through a round cylinder with through holes, avoiding blockage of the inlet during pumping, reducing the impact on the impeller, reducing the wear rate of the impeller, and improving the service life of the submersible pump. Moreover, it is easy to clean after blockage, only the round cylinder needs to be cleaned or replaced.

[0016] The interception structure 2 includes an external threaded cylinder 21. The upper surface corner of the external threaded cylinder 21 is fixedly connected to the lower surface of the submersible pump body 1 and is located outside the water inlet of the submersible pump body 1. The outer ring wall of the external threaded cylinder 21 is threaded. An internal threaded ring 22 is threadedly connected to the threaded part of the outer ring wall of the external threaded cylinder 21. A round hole cylinder 23 is fixedly connected to the lower surface corner of the internal threaded ring 22.
[0017] A mounting plate 4 is sleeved on the top of the outer wall of the power cord 3. A roller frame 5 is symmetrically fixedly connected to the upper surface of the mounting plate 4. A roller 6 is rotatably connected to the inner wall of the roller frame 5. A crank 7 is fixedly connected to one end of the roller 6. A rope 8 is wound around the outer wall of the roller 6. The outer wall of the rope 8 is sleeved with the surface of the mounting plate 4 and is in clearance fit. A lifting ring 9 is wrapped and tied tightly at the other end of the rope 8. The lower surface of the lifting ring 9 is fixedly connected to the upper surface of the submersible pump body 1.
[0018] A strip groove is provided on one side of the upper surface of the mounting plate 4. A connecting bend 10 is attached to the drain outlet at the bottom of the side wall of the submersible pump body 1. Both ends of the connecting bend 10 are provided with flanges. One end of the connecting bend 10 is bolted to the flange at the drain outlet at the bottom of the side wall of the submersible pump body 1. The flange at the other end of the connecting bend 10 is connected to a bellows 11, and both ends of the bellows 11 are provided with flanges. The flange at the other end of the bellows 11 is connected to a drain pipe 12, which is engaged with the strip groove on the upper surface of the mounting plate 4.
[0019] Working principle: When using a submersible pump to pump water underground, the submersible pump body 1 and power cord 3 form a complete submersible pump. Then, the interception structure 2 is installed. The external threaded cylinder 21 in the interception structure 2 is fixed to the bottom of the submersible pump body 1, positioned outside the water inlet. The internal threaded ring 22 is then fitted onto it. By rotating, the thread of the internal threaded ring 22 is connected to the rubber thread on the outer wall of the external threaded cylinder 21. At the same time, a round hole cylinder is also provided at the bottom of the internal threaded ring 22. Then, the submersible pump is moved to a suitable position in the well, and the power cord 3 is passed through the center of the mounting plate 4. Simultaneously, rope 8 is wound and secured to the lifting ring 9 on the surface of the submersible pump body 1 to ensure that the submersible pump will not fall off during use. The support plate 4 is placed on the wellhead surface and supported by its extended sides. The connecting bend 10 is then fitted to the drain outlet of the submersible pump body 1; both are equipped with flanges and are secured with bolts. The connecting bend 10 ensures that the drain outlet will not be affected by bending. A bellows 11 is connected to the flange at the other end of the connecting bend 10. The bellows 11 has excellent replaceability and can be adjusted according to the well layout. The depth is replaced, and a drain pipe 12 is connected to the flange at the other end of the corrugated pipe 11. The drain pipe 12 can be inserted through a slot on one side of the mounting plate 4 to fix the drain pipe 12. After completing the above operations, check to ensure that the bolts and pipe joints are firm and reliable. When the submersible pump body 1 is slowly lowered into the mine water source, the power cord 3 will slide downward at the center of the mounting plate 4. At the same time, the rope 8 wrapped around the outer wall of the rotating roller 6 will be lowered during the descent. By paying attention to the rotation of the crank handles 7 on both sides, when the submersible pump body 1 is completely lowered to the bottom of the mine, the rotating roller 6 will... Stop rotating, then connect the power cord 3 to make the submersible pump body 1 work. Pump water through the inlet at the bottom of the submersible pump body 1, and filter it through the round hole cylinder 23 of the interception structure 2 to intercept large impurities and prevent them from being sucked into the inlet and causing blockage. At the same time, observe the drainage situation of the drain pipe 12. Then disconnect the power to stop the pumping operation of the submersible pump body 1. If necessary, symmetrically crank the handle 6 to raise the submersible pump body 1 to the wellhead to clean the round hole cylinder 23. You can also prepare extra round hole cylinders 23 for replacement. This effectively leads the water out of the mine and to the surface or other designated locations.
