Zusammenfassung:	The utility model relates to a cabin dredging pump capable of effectively preventing an impeller from falling off. The cabin dredging pump comprises a bracket body, wherein a bearing assembly is fixedly arranged on the bracket body, and supports a pump shaft; a pump body is fixed on the front end of the bracket body; and an impeller is arranged in the pump body, and is arranged on the front end of the pump shaft. The cabin dredging pump is characterized in that a connecting screw thread of the impeller and the pump shaft is a triple thread. According to the cabin dredging pump, the connection of the impeller and the shaft is the triple thread instead of a quadruple thread, so that a helical pitch of the thread is reduced, a lead angle of the thread is decreased, and the impeller is not easy to fall off.
