The invention discloses a dual-purpose sail having navigation aid and power generation functions. The dual-purpose sail comprises a pair of arc-shaped sail bodies mounted on a mast; the sail further comprises a support, the support comprises a bottom edge and two supporting arms, the distance between the two supporting arms is larger than the width of the arc-shaped sail body, and the arm length of each supporting arm is larger than the length of the arc-shaped sail body; a rotating shaft is horizontally installed between the two supporting arms, a radial through hole is formed in the middle of the rotating shaft, the mast penetrates through the radial through hole and is fixedly installed on the rotating shaft, and the sail body I and the sail body II are installed on the portions, on thetwo sides of the rotating shaft, of the mast; a cylindrical shaft section is arranged on one side of the rotating shaft and is used for mounting a coupler and connecting a generator; and the sail further comprises a positioning piece, and the positioning piece is used for fixing the relative positions of the mast, the arc-shaped sail body and the bracket. The sail has the advantages of being simple in structure, convenient to install, capable of avoiding deviating from the air route due to variability of wind power and wind direction and the like, and has predictable huge economic value and social value.

    本发明公开了一种具备助航与发电功能的两用型风帆:包括一对弧形帆体,安装在桅杆上;还包括支架,所述支架包括底边及两个支撑臂,两个支撑臂的间距大于弧形帆体的宽度,支撑臂的臂长大于弧形帆体的长度;两个支撑臂之间,水平安装有转动轴,转动轴的中部位置,开设有一径向通孔,桅杆穿过该径向通孔固定安装在转动轴上,所述帆体I、帆体II安装在转动轴两侧的桅杆上;在转动轴的一侧,设有一圆柱体轴段,用于安装联轴器,连接发电机;还包括定位件,用于固定桅杆、弧形帆体与支架之间的相对位置;本发明具有结构简单、安装方便以及可以避免由于风力和风向的多变性而引起的偏离航线等优点,具有可预期的较为巨大的经济价值和社会价值。
