Abstract

The invention relates to a stern water flow energy recovery and auxiliary propulsion device. The stern water flow energy recovery and auxiliary propulsion device includes an impeller, the impeller ismounted on a stern seal plate through a tail support, a wheel shaft of the impeller is connected with a stern transmission shaft which is parallel to the stern seal plate and vertically arranged in atransmission mode, the stern drive shaft is connected with an intermediate shaft inside a ship through a horizontal transmission shaft system and a vertical transmission shaft system in sequence. Oneend of the intermediate shaft is connected with an engine and the other end of the intermediate shaft is connected with the propeller. The stern water flow energy recovery and auxiliary propulsion device uses the rear stern turbulence energy to assist a propeller for auxiliary propulsion, the efficiency of the transmission shaft systems is promoted, and the goal of saving engine energy consumptionis achieved.

Description

technical field [0001] The invention relates to the technical field of ship navigation energy saving, in particular to an auxiliary propulsion device for recovering water flow energy at the stern of a ship. Background technique [0002] The ship drive motor transmits power to the propeller through the shaft system, which will cause specific power loss, which is not conducive to meeting the environmental protection requirements of the drive motor to achieve energy saving and emission reduction; and in the prior art, some energy-saving devices used adjust the flow field at the stern to To increase propeller efficiency, some use clean energy such as wind energy to assist propulsion. The disadvantage of these techniques is that they cannot improve the transmission efficiency of the propeller drive shafting. Contents of the invention [0003] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides an auxiliary propulsion device...
