The invention discloses a buoyancy device and system with vortex-induced vibration suppression performance. The buoyancy device comprises a buoyancy device body, and the buoyancy device body comprises two buoyancy half tiles which are spliced with each other; three rows of same spiral strakes are arranged on the surface of the buoyancy device body, the three rows of spiral strakes are uniformly distributed at an angle of 120 degrees, each row of spiral strakes comprises four fins with specific parameter appearances, and every two adjacent fins are arranged at intervals. The spiral strake structure is additionally arranged on the buoyancy device body to restrain vortex-induced vibration of the marine pipeline provided with the buoyancy device, that is, formation of vortexes is destroyed through the fins, the vortex shedding frequency is greatly reduced, the inherent frequency of the marine pipeline is avoided, and therefore the purpose of restraining the vortex-induced vibration of the marine pipeline is achieved.
本发明公开了一种具有涡激振动抑制性能的浮力装置和系统。所述浮力装置包括浮力装置本体,浮力装置本体包括两个相互拼合的浮力半瓦;在所述浮力装置本体表面上设有三列相同的螺旋列板,三列螺旋列板呈120°均匀分布,每列螺旋列板包括四个特定参数外形的鳍,相邻两鳍之间间隔排列。本发明通过在浮力装置本体上附加螺旋列板结构来抑制装有浮力装置的海洋管道的涡激振动,即通过鳍破坏旋涡的形成,大幅度降低涡脱频率,避开海洋管道的固有频率,从而达到抑制海洋管道涡激振动的目的。
