Pod-type water spraying propeller

Abstract

The invention provides a pod-type water jet propulsion unit, which comprises an installation platform, a pod propeller bracket arranged at the lower end of the installation platform, a pod propeller cabin body arranged at the lower end of the pod propeller bracket, a pod propeller cabin body arranged at the pod propulsion The motor base in the cabin body, the motor installed on the motor base, the transmission shaft connected to the output end of the motor, the water jet propulsion pump installed on the transmission axis, the lower end of the pod propeller cabin is provided with an inlet, a side A spout is provided, a flow channel is formed between the inlet and the spout, and the spout is set facing the water jet propulsion pump, and the upper end of the installation platform is provided with a data transmitter and a hydraulic steering device. The present invention is on the basis of maintaining the advantages of the original water jet propeller, adding the bracket, cabin body, electric propulsion system and steering device of the pod propeller, thereby reducing the complicated mechanical transmission mechanism and reversing device of the water jet propeller, further The propulsion efficiency and operational performance of the thrusters are improved, the noise is reduced and the stealth performance is enhanced.

Description

technical field [0001] The invention relates to a propeller, in particular to a pod type water jet propeller. Background technique [0002] With the rapid development of the times, high-performance ships have gradually entered people's field of vision. In the field of high-performance ships, water jet propulsion devices have begun to play their own unique advantages. As a special propulsion device, water jet propulsion has a history of nearly 400 years, and it was first used in ship propulsion at the end of the 19th century. With its high propulsion efficiency, good anti-cavitation performance, significant vibration and noise reduction effect and good stability, it is widely used in warships, nuclear submarines, minesweepers, landing ships, high-speed ships, port operation ships, amphibious landings Ships and other special ships. However, the mechanical transmission mechanism of the water jet propeller is relatively complex, bulky, complicated to replace the pump impeller...

AI Technical Summary

Problems solved by technology

However, the mechanical transmission mechanism of the water jet propeller is relatively complex, bulky, complicated to replace the pump impeller, and poor turning and reversing performance, which seriously limits its wide application

At the same time, with the development of domestic and foreign ships in the direction of miniaturization, invisible navigation, high speed, modular installation and energy saving, the traditional form of water jet propulsion can no longer meet the current development trend at home and abroad.
