The present invention relates to a coupling device for a submersible propeller pump, which couples a submersible pump with a column pipe that drains a fluid stored in a tank. The coupling device for a submersible propeller pump is used to couple a submersible pump with a column pipe that drains a fluid stored in a tank, and comprises: a pump support part which protrudes inwardly from an inner circumference of the column pipe and on which the submersible pump is put; a fixing pipe which is installed around the inner circumference of the column pipe, and guides the movement of the submersible pump and supports the submersible pump when the submersible pump is installed; an edge part which protrudes outwardly the submersible pump so as to be put on the pump support part; and an insert groove which is formed in the edge part and into which the fixing pipe is inserted. Therefore, the coupling device for a submersible propeller pump according to the present invention can strengthen the support force of the submersible pump installed inside the column pipe, thereby preventing the deviation of the submersible pump from the pump support part, and absorb vibration generated from the submersible pump, thereby preventing the damage of the submersible pump or the column pipe and inhibiting the generation of noise. |
