The invention discloses a ship energy-saving device for reducing ship bow resistance, which is characterized by comprising a ship bow ballast water device and a ship energy-saving device, and the ship bow ballast water device and the ship energy-saving device share a ballast pipe (20); the ballast pipe (20) longitudinally penetrates through the anti-collision bulkhead (110) and is arranged in the fore peak tank (100) and the ballast left tank (101); the ship energy-saving device further comprises a water inlet tank (1), a first water outlet tank (2) and a second water outlet tank (3). A communicating pipeline is arranged in the ship body to connect the bow and seawater on the two sides of the front shoulder of the ship body, the seawater can be automatically supplemented to the areas on the two sides of the front shoulder of the low-pressure ship body from the high-pressure bow, and the purpose of reducing resistance in the ship running process is achieved. Compared with the prior art, the water conveying amount can be automatically adjusted along with the navigational speed, and manual adjustment and control are not needed; additions do not need to be added outside the ship body, and performance is stable. The device is simple, easy to operate, convenient to maintain and good in resistance reducing effect.
本发明公开了一种降低船艏阻力的船舶节能装置,其特征在于,包括:船舶艏部压载水装置、船舶节能装置,船舶艏部压载水装置与船舶节能装置共用压载管(20);压载管(20)纵向穿过防撞舱壁(110),设置在艏尖舱(100)和压载左舱(101)内;船舶节能装置还包括:进水箱(1)、第一出水箱(2)、第二出水箱(3)。在船体内部设置一条连通管道连接艏部及船体前肩两侧海水,海水就会自动地从高压力的艏部补充到低压力的船体前肩两侧区域,达到船舶行驶中降低阻力的目的。本发明与现有技术相比:可以随着航速高低自动调节输水量,不需要人为调节控制;不用在船体外增设附加物,性能稳定;该装置简单,操作容易,维护方便,降阻效果好。
