Novel submersible pump structure for preventing well rotation

The utility model discloses a novel submersible pump structure for preventing well rotation, which comprises pump part combinations, a pin bearing body is inserted on the pump part combinations, a water outlet shell is inserted on the pin bearing body, a plurality of impeller structures are rotatably mounted in the pump part combinations, and a pair of pump part combinations which are adjacent up and down are connected in an inserted manner. The utility model relates to the technical field of centrifugal pumps, in particular to a novel anti-rotation submersible pump structure for a well, which realizes anti-rotation of a single-stage pump assembly, anti-rotation among pump assembly, anti-rotation between the pump assembly and a pin bearing body, and anti-rotation between the pin bearing body and a shell through the steps, and further realizes integral anti-rotation of the submersible pump for the well. Meanwhile, the anti-rotation device has the advantages of being simple in structure and high in production a
