The invention discloses a compound anchor system for depth-keeping mooring of an underwater platform, and belongs to the technical field of underwater equipment. A bowl-shaped rotating body hydrodynamic appearance scheme is adopted, the design contradiction between resistance reduction and stability in theory is solved through the design that size parameters are combined with the evenly-distributed water permeable holes, the resistance coefficient is optimal under the condition of the large incident flow area, and on the premise that it is guaranteed that the resistance of the compound anchor meets the depth-keeping speed requirement of an underwater platform, the effect that the underwater platform depth-keeping speed requirement is met is achieved. And the damage of a large incident flow area to the attitude stability in water is avoided. Besides, by adopting the scheme of integrating an adjustable buoyancy structure and a counterweight structure and through the mass-buoyancy center design facing the dynamic stability, the large mass-buoyancy center distance of the compound anchor system on the axis of a rotating body is achieved, it is ensured that the compound anchor system keeps good underwater descending posture stability, cable tension vibration sudden change in the depth setting process is reduced, and the cable tension vibration sudden change in the depth setting process is reduced. And stable and accurate depth setting of the underwater platform is ensured.

    一种用于水下平台定深系泊的复式锚系统,属于水下装备技术领域。本发明采用碗型旋转体水动外形方案,通过尺寸参数与均布透水孔结合设计,解决了理论上减阻与稳定性的设计矛盾,实现了大迎流面积条件下的阻力系数最优,在确保复式锚阻力满足水下平台定深速度要求的前提下,避免了大迎流面积对水中姿态稳定性的损害。此外,本发明采用可调节浮力结构与配重结构集成方案,通过面向动稳定性的质浮心设计,实现了复式锚系统在旋转体轴线上较大的质浮心距,确保其保持较好的水中下降姿态稳定性,减小定深过程缆绳张力震荡突变,保证水下平台定深稳定准确。
