Anti-winding ship nacelle and protection method thereof

Abstract

The invention discloses an anti-winding ship nacelle and a protection method thereof. The nacelle comprises a nacelle body, a partition plate is arranged in the nacelle body, and the nacelle body is divided into an equipment cavity and a buffer cavity through the partition plate; placement plates are arranged at the side, facing the equipment cavity, of the partition plate, a motor is arranged atthe tops of the placement plates, and a first connection shaft is arranged at the output end of the motor; a propeller is arranged at one side of the nacelle body and comprises a rotation shaft, and spiral blades are arranged at the outer side of the rotation shaft. According to the anti-winding ship nacelle, by arranging the protection cover, multiple winding rods are evenly arranged in the protection cover, winding hooks at the outer sides of the winding rods can wind sea grass or ropes entering the protection cover, and the proportion of propeller winding is reduced; all the winding rods are obliquely arranged, all the winding rods can be effectively staggered, and the protection efficiency of the winding rods and the winding hooks can be improved.

Description

Technical field [0001] The invention relates to the technical field of ship equipment, in particular to an anti-winding ship pod and a protection method. Background technique [0002] Pod propeller, also known as POD propeller, is a new type of ship propulsion device that integrates propulsion and steering devices. The pod propulsion device places the propulsion motor outside the cabin and is directly connected to the propeller. It can be 360° Rotate horizontally inside to achieve vector propulsion. [0003] The patent text of the application publication number CN 204056276 U discloses a ship pod propeller. Through a reasonable propeller structure, the motor speed can be increased to several times or even dozens of times that of the conventional pod propeller. The speed is in an optimal working range to improve the efficiency of the motor; this structure can also greatly reduce the volume and weight of the motor and the pod to reduce the water resistance of the pod; at the same ti...

[0003] The patent text of the application publication number CN 204056276 U discloses a ship pod propeller. Through a reasonable propeller structure, the motor speed can be increased to several times or even dozens of times of the motor speed in conventional pod propellers, which can make the motor The rotating speed is in an optimal working range, which improves the efficiency of the motor; this structure can also greatly reduce the volume and weight of the motor and the pod, so as to reduce the water resistance of the pod; at the same time, the first propeller and the second propeller Turning to the opposite direction, through a reasonable design, the circumferential induced velocity in the wake tends to zero, which can improve the propulsion efficiency of the ship and achieve energy saving and emission reduction. However, in the actual use process, in order to reduce the water resistance of the pod, the The propeller is set on the outside of the pod without any protective device. When running in water, when encountering floating seaweed or rope, the seaweed or rope will wrap around the propeller, and the entanglement will become tighter, resulting in damage to the propeller. huge damage to ships
