The invention belongs to the technical field of ship hydraulic systems, and particularly relates to a non-retractable fin stabilizer hydraulic system and a control method.The non-retractable fin stabilizer hydraulic system comprises a locking mechanism, a fin handle, a fin rotating oil cylinder set and a control valve set, and the control valve set is connected with the locking mechanism and oil cavities of two fin rotating oil cylinders; when the control valve group applies thrust in the same size and direction to the two fin rotating oil cylinders, the torques of the two fin rotating oil cylinders acting on the fin handle are the same and are opposite in direction, the fin handle is reset, and the control valve group controls a telescopic pin of the locking mechanism to extend into a pin hole of the fin handle to lock the fin handle; and when the control valve group alternately applies forces in different directions to the two fin rotating oil cylinders, the fin handle rotates at the moment. According to the non-retractable fin stabilizer hydraulic system, the fin rotating oil cylinder can be controlled to drive the fin handle to rotate, the torque acting on the two ends of the fin handle can be precisely controlled to reach balance, and it is ensured that the fin handle after zero resetting can achieve in-place locking or in-place unlocking of a fin through a telescopic pin of the locking mechanism.
本申请属于船舶液压系统技术领域,具体涉及一种非收放式减摇鳍液压系统和控制方法,非收放式减摇鳍液压系统包括锁紧机构、鳍柄、转鳍油缸组和控制阀组,控制阀组分别与锁紧机构和两个转鳍油缸的油腔连接;当控制阀组向两个转鳍油缸施加大小方向相同的推力,两个转鳍油缸作用在鳍柄的转矩相同方向相反,鳍柄复零,控制阀组控制锁紧机构的伸缩销伸入鳍柄的销孔锁紧鳍柄;当控制阀组向两个转鳍油缸交替施加方向不同的力,此时鳍柄回转运动。本申请的非收放式减摇鳍液压系统不仅能够控制转鳍油缸带动鳍柄回转,还能够精准控制作用在鳍柄两端的转矩达到平衡,确保复零后的鳍柄可以通过锁紧机构的伸缩销实现对鳍的锁紧到位或解除锁紧到位。
