[0002] A deep well submersible pump is a water-lifting device that integrates a motor and pump, operating submerged in water. Deep well submersible pumps offer advantages such as simple structure, high efficiency, low noise, safe and reliable operation, and convenient installation and maintenance. They are suitable for extracting water from deep wells, hot water wells, and the ocean, and can also be used for extraction from rivers, reservoirs, and canals. Primarily used for farmland irrigation and water supply for people and livestock in high-altitude mountainous areas, they can also be used for water supply and drainage in cities, factories, railways, mines, and construction sites.

[0003] Currently, most deep well submersible pumps are directly exposed in the well. When pumping water from an open well, gravel from the borehole wall falls into the submersible pump, which can easily damage it. In addition, the submersible pump inlet does not have a function to clean debris, which can easily clog the inlet and affect the normal operation of the submersible pump.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0020] The working principle of this implementation plan is as follows: The electrical equipment used by this device is controlled by an external controller. When using it, the user first passes the deep well submersible pump through the cleaning ring 11 and places the bottom on the support seat 5. During clamping: The rotating rod 12 is movably inserted into the top rear end of the protective shell 1 via a sealed waterproof bearing. The rotating handle 13 is installed on the right end of the rotating rod 12. A set of opposing external threads 14 are tapped on both sides of the outer surface of the rotating rod 12. A set of nuts 15 are fitted onto the set of opposing external threads 14. The round rod 16 is fixedly installed in the top front end of the protective shell 1.

The rotating end of the drive motor 6 is connected to the rotating lead screw 7 via a set of transmission gears 22. Cleaning brushes 23 are evenly installed on the inner side of the cleaning ring 11. Figure 2 and Figure 3 As shown, the bearing seat 5 has an inner cavity. Water flows into the protective shell 1 after being filtered through the annular filter screen 4, and is used by the deep well submersible pump for pumping. When it is necessary to clean the inlet of the deep well submersible pump, the drive motor 6 is turned on. The drive motor 6 drives the cleaning ring 44 to move up and down, which can clean the impurity filter screen at the inlet of the deep well submersible pump and prevent debris from clogging the impurity filter screen at the inlet of the deep well submersible pump. The protective shell 1 can protect the deep well submersible pump and prevent the pump from being damaged by the stone fragments on the borehole wall.
