The invention relates to the technical field of sails in ship and ocean engineering, in particular to a winch lifting and fixing mast type hard wing sail which comprises a sail base, and the end face of the sail base is connected with a rotation driving assembly through bolts. The problems that a hydraulic system is complex, high in failure rate, large in system pressure, not in place in lifting, difficult in oil leakage sealing at a rotary joint, easy to stop and capable of maintaining pressure constantly are avoided, a hydraulic station can be omitted after the hydraulic system is changed into a winch system, and the problems that the lifting system is high in failure rate and high in cost in practical application are effectively solved; the lifting weight and friction force are reduced, the stability of the sail in the lifting process is improved, a sail lifting system is more concise and easy to operate, the sail skin and the sail frame are made of composite materials, the weight of the sail is reduced, and meanwhile the situation that the sail lifting friction force is increased after steel corrosion is avoided.
本发明涉及船舶与海洋工程中的风帆技术领域,尤其为一种绞车升降固定桅杆型硬翼风帆,包括风帆基座,所述风帆基座的端面通过螺栓连接有回转驱动组件,本发明通过将升降系统由液压改为绞车滑轮升降,避免了液压系统复杂故障率高,系统压力大,升降不到位、旋转接头处漏油密封难、容易暴死,并且需要时时保压,改为绞车系统后可取消液压站,有效的解决在实际应用中发现该升降系统故障率多、成本高的问题,并且升降桅杆修改为固定桅杆,减少了升降重量和摩擦力,提高了风帆在升降过程中的平稳度,使得风帆升降系统更加简洁、易操作,以及通过复合材料作为帆叶蒙皮和帆叶框架,降低力帆叶的重量,同时避免了钢材腐蚀后所增加帆叶升降的摩擦力。
