This utility model discloses a combined small submersible sewage pump, relating to the field of sewage pump technology. It includes a base, with a bottom shell fixedly connected to the top of the base. A reinforcing ring is fixedly connected to the outer side of the bottom shell, and the bottom end of the reinforcing ring is fixedly connected to the top of the base. A first connecting plate is fixedly connected to the top of the bottom shell, and a second connecting plate is threadedly connected to the top of the first connecting plate. Using this structure, the second locking block is adjusted to a position that is not directly corresponding to the second locking slot, thereby effectively locking and limiting the first locking block to fix the position of the second connecting plate. When cleaning the drain pipe later, the first locking block is rotated, and the second locking block is adjusted to a position symmetrical to the second locking slot, allowing the first locking block to be directly pulled out to bring out the drain pipe. This facilitates the user's ability to easily disassemble and clean the drain pipe individually.
