The invention discloses a stern rectifying fin energy-saving device for a ship. A rectifying fin is arranged in a stern area of the ship and has a certain curvature; the tail ends of the rectification fins are in streamline design, so that disturbance of water flow is reduced, and the stability of the water flow is optimized; the rectifying fins effectively reduce tail vortex and turbulent flow by changing the flow direction and the flow speed of water flow, and the resistance of a ship is reduced. The rectifying fins are adjustable in structural design and can be adjusted according to different navigational speeds and using environments, and the optimal performance is achieved. According to the stern rectifying fin energy-saving device for the ship, the propelling efficiency of a ship propelling system is improved, the resistance of the ship during sailing is reduced, and therefore fuel consumption and operation cost are reduced.
本发明公开了一种船用艉部整流鳍节能装置,所述整流鳍设置于船舶的艉部区域,并具有一定的弯曲度;所述整流鳍的末端呈现流线型设计,以减少水流的扰动,优化水流的稳定性;所述整流鳍通过改变水流流向和流速,有效减小尾部涡流和湍流,降低船舶的阻力;所述整流鳍的结构设计具有可调性,可以根据不同航速和使用环境进行调整,达到最佳性能。本发明提供的船用艉部整流鳍节能装置,提高了船舶推进系统的推进效率,降低了船舶航行时的阻力,从而节省了燃料消耗和运营成本。
