The invention discloses a layered heaving buoy and a wave suppression method, and belongs to the field of offshore semi-submersible platforms, the layered heaving buoy comprises a buoy main body, a heaving plate is fixed at the lower end of the buoy main body, a cavity is formed in the buoy main body, a partition plate is fixed in the cavity and divides the cavity into an outer cavity and an inner cavity, a piston plate is arranged in the inner cavity, and the inner cavity is divided into an upper cavity and a lower cavity by the piston plate; connecting rods are fixedly connected to the lower surface walls of the piston plates; a spoiler is fixed at the lower end of the connecting rod, and comprises a disc-shaped center plate, a plurality of spoilers and a plurality of spoilers, the center plate is fixedly connected with the connecting rod; the center plate is sleeved with the surrounding ring, and the axis of the surrounding ring coincides with the axis of the center plate; the central plate is fixed in the middle of the surrounding ring; an elastic mechanism is arranged in the upper cavity and comprises an installation base and a spring, the installation base is fixed in the upper cavity, one end of the spring abuts against the installation base, and the other end of the spring abuts against the upper surface wall of the piston plate. According to the buoy and the method, the vortex phenomenon can be disturbed through the spoilers, and the stability of a platform is improved.
本发明的一种分层式垂荡浮筒及抑浪方法,属于海上半潜式平台领域,包括浮筒主体,浮筒主体的下端固定有垂荡板,浮筒主体中设有空腔,空腔中固定有隔板,隔板将空腔分为外腔和内腔,内腔中设有活塞板,活塞板将内腔分别上腔和下腔;活塞板下表壁固定连接有连杆;连杆的下端固定有扰流板,扰流板包括:中心板,为圆盘形,轴线与连杆的轴线重合;中心板与连杆固定连接;围环,套设在中心板上,围环的轴线与中心板的轴线重合;中心板固定在围环的中间位置;上腔中设有弹性机构,弹性机构包括安装座和弹簧,安装座固定在上腔中,弹簧的一端与安装座抵接,另一端与活塞板上表壁抵接。本浮筒及方法能通过扰流板干扰涡流现象,提高平台的稳定性。
