The invention discloses a ship stern combined hydrodynamic energy-saving synergistic system which comprises a propeller, a pair of flow guide fins, a pair of rudder thrust fins and a pre-rotation fin, the pre-rotation fin is arranged on the port side of a ship stern casting in front of the propeller, and the pair of flow guide fins are arranged on the port side and the port side of a ship body in front of the pre-rotation fin in a mirror symmetry mode. And the pair of rudder thrust fins are rotationally connected with the ship body, are arranged on the left and right sides of the rudder behind the propeller in a mirror symmetry manner, and are rotationally connected with the rudder. According to the combined hydrodynamic energy-saving and efficiency-improving system for the ship stern, an energy-saving device can be adjusted in a self-adaptive mode according to the flow field form, and the utilization rate of the beneficial flow field is high; energy-saving devices are organically combined for use, so that the thrust efficiency is greatly improved; the energy-saving device is simple in structure and low in manufacturing and mounting difficulty and cost; the wake flow rotation degree is low, and the recovery and reutilization rate of wake flow rotation energy is high.
本发明公开了一种船舶艉部组合式水动力节能增效系统,包括螺旋桨、一对导流鳍、一对舵推力鳍和预旋鳍,所述预旋鳍设于螺旋桨前方的船体艉部铸件的左舷侧,一对所述导流鳍镜像对称设于位于预旋鳍前方的船体的左右舷侧,与船体转动连接,一对所述舵推力鳍镜像对称设于螺旋桨后方的船舵的左右舷侧,并与船舵可转动连接。本发明提供一种船舶艉部组合式水动力节能增效系统,节能装置可根据流场形态自适应调节,有益流场利用率高;节能装置有机组合使用,推力效率提升幅度大;节能装置结构简单,制造和安装的难度及成本低;尾流旋转程度低且尾流旋转能量的回收及再利用率高。
