The invention discloses a suction anchor device for preventing an anchor chain from bottoming and slotting and avoiding a mooring impact load. The suction anchor device comprises a suction anchor cylinder with a downward opening, an external anchor chain and a suction hole valve located on a top plate of the suction anchor cylinder. A center hole is formed in the center of the top plate; a partition plate located below the top plate is arranged in the suction anchor cylinder. A connecting column extending to the position above the partition plate penetrates through the center hole. The suction hole valve is connected with a suction pipeline, and the suction pipeline extends downwards to penetrate through the partition plate. A coaxial internal buffer spring is arranged in the connecting column; a coaxial external buffer spring is arranged outside the connecting column; an external elastic rope is connected between the upper section plate and the top plate of the connecting column, and an internal elastic rope is connected below the lower section plate and the upper surface of the partition plate; and a spiral plate is arranged below the partition plate in the suction anchor cylinder. The impact load generated by an external anchor chain is relieved, and the overall bearing performance is improved; the potential safety hazard that the anchor chain reciprocates along with the floating body structure to cut the soil, so that the soil is liquefied and washed away by water flow to form a groove is avoided.

    本发明公开了一种用于防止锚链触底开槽及避免系泊冲击载荷的吸力锚装置,包括开口向下的吸力锚筒,外部锚链,位于吸力锚筒的顶板上的抽吸孔阀门;顶板的中心开设有中心孔;吸力锚筒内有位于顶板下方的隔板;中心孔内贯穿有延伸至隔板的上方的连接柱;抽吸孔阀门连接有抽吸管道,抽吸管道向下延伸至穿过隔板;连接柱内有同轴心的内部缓冲弹簧;连接柱外有同轴心的外部缓冲弹簧;连接柱的上段板与顶板之间连接有外部弹性绳,下段板的下方与隔板的上表面连接有内部弹性绳;吸力锚筒内隔板的下方设有螺旋板。本发明缓解了外部锚链产生的冲击荷载,提高了整体的承载性能;避免了锚链随浮体结构物作往复运动切割土壤导致土壤液化被水流冲走形成沟槽出现安全隐患。
