The invention discloses a ship and a sail for the ship. The sail for the ship comprises two supporting legs and a louvered sail body supported by the two supporting legs. The louvered sail body comprises an upper cross beam, a lower cross beam, a plurality of sail blades arranged longitudinally and a plurality of electromagnetic limiting stop pins. Each sail blade comprises a blade body, and an eccentric shaft is arranged at the position, away from L1, of one side of the longitudinal axial symmetric line of each blade body. The two eccentric shafts are respectively an upper eccentric shaft anda lower eccentric shaft which are coaxially arranged; in the two eccentric shafts, one eccentric shaft is connected with the power output end of a driving device, and the other eccentric shaft is provided with an angle sensor; for each sail blade, at least one electromagnetic limiting stop pin is mounted on the upper cross beam and the lower cross beam respectively. The ship and the sail for theship are simple and reliable in overall structure, high in wind energy absorbing efficiency, greatly reduced in manufacturing cost and simple in daily maintenance.
本发明公开了一种船舶及其船用风帆。所述的船用风帆包括两个支腿以及通过两个支腿支撑的百叶式风帆,百叶式风帆包括上横梁、下横梁、若干片纵向布置的风帆叶片、若干个电磁式限位挡销;风帆叶片包括叶片本体,叶片本体在纵轴向对称线的一侧,距离为L1的位置处设置偏心轴;偏心轴有两根,分别为同轴设置的上偏心轴、下偏心轴;两根偏心轴中,其中一根偏心轴与驱动装置的动力输出端连接,另一根偏心轴上则安装有角度传感器;针对每一片风帆叶片,均分别在上横梁、下横梁上至少安装一根电磁式限位挡销。本发明整体结构简单可靠、汲取风能效率高、制造费用大幅降低、日常维护保养简单。
