Abstract

The invention belongs to the field of underwater propellers, and particularly relates to a tandem type motor pump jet propeller which comprises a flow guide pipe, a rotating paddle, a multi-winding tandem type motor driving mechanism and a flow guide static blade set, and the rotating paddle and the flow guide static blade set are sequentially installed in an inner cavity of the flow guide pipe in the direction from the upstream end to the downstream end of the flow guide pipe. The multi-winding tandem type motor driving mechanism is used for driving the rotating paddle to rotate so as to suck water flow from the upstream end of the flow guide pipe; the flow guide static blade set is used for guiding the water flow in the flow guide pipe so as to spray the water flow from the downstream end of the flow guide pipe; and the flow guide pipe is provided with a pod type installation position. The multi-winding tandem type motor driving mechanism is used for driving, heat dissipation is facilitated, the radial size can be reduced through the tandem form, and the upstream face of the propeller is reduced; and under the condition that the disc surface of the rotating paddle is not changed, the torque can be increased, and the whole power density is improved.

Description

Technical field[0001]The present invention belongs to the field of underwater propeller, and in particular to a serial motor pump spray propeller.Background technique[0002]The pump spray push is a combined propulsion device composed of a cyclic catheter, a stator and a rotor, has the advantages of good manipulation, high mobility, strong anti-air resistance, has been applied to the ship. For example, a patent document is disclosed as CN 107972837A, a combined pump spray propeller, including an external conduit, an outer conduit is contracted, and the outer conduit is inlet and water, respectively, and the pump spray propeller is provided inside the propeller. The pump propeller, the pump spray propeller includes a pump spray rotor, a pump fake stator and a pump sprayer, and the pump sprayer is fixed to the outer conduit by four fixed wings, and the rear of the pump spray is connected to the pump spray rotor. The pump is discharged, and the pump spray stator is connected to the outer...
