The invention relates to the technical field of marine equipment, and discloses a floating platform underwater drag parachute and a floating platform, and the floating platform underwater drag parachute comprises a mounting shaft, a first mounting seat, a second mounting seat and a plurality of baffles. According to the water power principle, when the baffles have the relative movement speed in the vertical direction, the baffles can generate reverse downward damping force, the damping force and the area of the baffles are in a linear relation, the damping force and the movement speed are in a cubic relation, and when the sea condition is stronger, the movement speed of the baffles is higher, and the stable damping force provided for the floating platform is larger; the damping umbrella system belongs to passive damping, the energy of surges is used for providing motion damping for the floating platform, stable damping is provided when the floating platform fluctuates up and down, and the purpose of restraining the motion amplitude of the floating platform is achieved.
本发明涉及海洋设备技术领域,公开一种浮式平台水下阻力伞和浮式平台,浮式平台水下阻力伞包括:安装轴、第一安装座、第二安装座、多个挡板。本申请利用水动力原理,当挡板在垂直方向上具有相对运动速度时,挡板会产生反向向下的阻尼力,阻尼力和挡板面积呈线性关系,和运动速度成三次方关系,当海况越强时,挡板运动速度越大,为浮式平台提供的稳定阻尼力越大,阻尼伞系统属于被动阻尼,利用浪涌的能量为浮式平台提供运动阻尼,使在浮式平台产生上下起伏运动时提供稳定阻尼,以达到遏制浮式平台的运动幅度的目的。
