Pod thruster capable of improving hydrodynamic performance and arrangement structure thereof

Abstract

The invention discloses a pod thruster capable of improving hydrodynamic performance and an arrangement structure thereof. The pod thruster comprises a propeller and a pod underwater shell; the top ofthe pod underwater shell is connected with a ship body; the propeller is installed at the tail end of the pod underwater shell; the pod thruster structure further comprises a flow guide pipe, an upper support frame and a lower support frame; one end of the upper support frame and one end of the lower support frame are connected with the upper portion and the lower portion of the pod underwater shell respectively; the other end of the upper support frame and the other end of the lower support frame are connected with the upper portion and the lower portion of the flow guide pipe respectively;the periphery of the propeller is sleeved with the flow guide pipe; and a certain gap is reserved between the flow guide pipe and the propeller. According to the pod thruster, the flow guide pipe canbe supported through the upper support frame and the lower support frame, the section of the flow guide pipe is in a wing shape, and due to the fact that the inlet area of the flow guide pipe is larger and the outlet area of the flow guide pipe is small, when the rotating speed, the diameter, the blade shape and the like of the propeller are the same, the propelling efficiency of the propeller canbe improved through the flow guide pipe, and larger thrust is provided.

Description

technical field [0001] The invention belongs to the technical field of pod propellers, and in particular relates to a pod propeller structure and a hull arrangement form that can improve hydrodynamic performance. Background technique [0002] Due to the advantages of low noise and low vibration, pod propellers have been widely used in diving supply ships, oil drilling platforms, supply ships, shuttle tankers, ro-ro ships, icebreakers and some military ships. The pod propeller places the propulsion motor outside the cabin, and the electric energy generated by the generator is transmitted to the motor outside the cabin through the cable, and the motor directly drives the propeller to rotate to provide power for the ship. [0003] However, due to the special requirements of some ship types / working platforms, the propeller is required to have better thrust and sailing capability under the condition of a certain main engine power. Due to the structural limitations of some ship ty...
