[0017] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0018] like Figure 1 The submersible pump for wells shown is easy to clean and not prone to clogging, including: pump body 1, pump cover 2, fixed protective cover 12, first pull rope 16 and movable protective cover 6. The pump cover 2 is located at the bottom of the pump body 1 and can be fixed with screws, making it easy to disassemble and assemble.

[0019] A lifting lug 19 is provided on the top of the pump body 1, and a second pull rope 17 is provided on the lifting lug 19 to facilitate the placement of the pump body 1 into the deep well and the pulling rope 17 to pull it out upward.

[0020] The fixed protective cover 12 is installed at the bottom water inlet of the pump cover 2. The side wall of the fixed protective cover 12 is provided with first filter holes 5 at intervals to filter the incoming water and prevent damage to the impeller in the pump cover 2. The fixed protective cover 12 can be fixed to the bottom of the pump cover 2 with screws, and the structure is stable.

[0021] The movable protective cover 6 is fitted onto the lower part of the fixed protective cover 12. The inner diameter of the movable protective cover 6 corresponds to the outer diameter of the fixed protective cover 12, with a small gap. The side wall of the movable protective cover 6 is provided with second filter holes 4 that correspond one-to-one with the first filter holes 5. External water flows through the second filter holes 4 into the first filter holes 5, and then into the pump cover 2, thereby achieving filtration of the incoming water.
