The invention discloses a ship bow energy-saving device which is applied to a ship with bulbous bow characteristics and comprises shape-preserving plates arranged on the two sides of a ship bow. The front edges of the two shape-preserving plates are arranged in the vertical direction and connected together, the top of the combination position of the front edges of the two shape-preserving plates is connected with the inclined section of the ship bow to form a top intersection point, and the bottom of the combination position is connected with the point at the foremost end of the bulbous bow. The height of the top edge of the shape-preserving plate is flush with the top intersection point, and the bottom edge of the shape-preserving plate is flush with a point at the foremost end of the bulbous bow; the top edge, the bottom edge and the rear edge of the shape-preserving plate are all in smooth connection with the surface of the original ship body. The device can be applied to a ship with bulbous bow characteristics, the wave resistance increase of the built ship can be reduced through the device, and the original bulbous bow of the ship does not need to be dismantled in the refitting process.
本发明公开了一种船舶艏部节能装置,应用于具有球艏特征的船舶,其包括设置于船艏两侧的保形板;两个所述保形板前边缘沿竖直方向设置且连接在一起,二者前边缘的结合处在顶部与船艏倾斜段连接形成顶部交点,在底部与球鼻艏最前端的点连接;所述保形板的顶部边缘的高度与所述顶部交点平齐,底部边缘与所述球鼻艏最前端的点平齐;所述保形板的顶部边缘、底部边缘以及后边缘均与原始船体的表面光顺连接。本发明的装置可应用于具有球鼻艏特征的船舶,通过本装置可减小已经建造好的船舶的波浪增阻,且改装过程不必拆除船舶原有的球鼻艏。
