A sealing ring is arranged between the inner wall of the annular structure of the baffle II and the outer wall of the rotating shaft, so that a cavity above the baffle II can be well sealed and protected. The sealing ring is arranged between the inner wall of the annular structure of the baffle II and the outer wall of the rotating shaft, and the rotating shaft is allowed to normally rotate as long as the requirement is met.

Further, still be equipped with gaseous buffer structure on the baffle II, gaseous buffer structure includes piston, gasbag.

Through still being equipped with gaseous buffer structure on baffle II, at the motor operation in-process, the mainly used is expanded with heat and contract with cold gaseous, plays the guard action to the motor.

Furthermore, the top end of the shell is provided with a hanging ring, and/or the bottom end of the shell is provided with a base. The submersible pump can be effectively maintained to be vertically and stably placed by arranging the lifting ring and/or the base.

The utility model discloses have following advantage and beneficial effect:

the utility model provides a submersible pump air seal structure with simple structure, before using, the bottom end of the cylinder structure is inserted into the water body, and the top of the cylinder structure is kept above the water surface; because the tubular structure top is sealed cavity structures, along with barrel bottom immerse gradually in the aquatic, the air pressure crescent in the cavity of top installation motor in the tubular structure to the great pressure of surface of water output that gets into by the tubular structure bottom, thereby the cavity is formed to the cavity of top installation motor in the tubular structure. When the water lifting device is used, the motor drives the rotating shaft to rotate, and the rotating shaft drives the impeller to rotate so as to lift water; at this moment, the pivot still can drive baffle I and rotate, and the impeller stirs the splash that upwards sputters and contacts with baffle I earlier, and the plate contact is gone up through baffle I, through baffle I's rotary motion, changes the trend of splash, produces centrifugal action to the splash, and the splash that will upwards sputter is along the level to, or is unrestrained downwards, finally falls back to the water in, plays good effect of blockking, prevents in the water splash motor storehouse.
