螺旋升降式吸力锚舱盖设计

Design of helical lift suction anchor hatch cover

吸力锚舱盖作为吸力锚的主要结构部件,用于吸力锚下沉过程中气体、液体等的排出,其结构尺寸与启闭、锁紧方式对吸力锚下沉的稳定性、速度、操作的便利性等都有重要影响.本文创新性地提出了一种螺旋升降式吸力锚密封舱盖,基于螺杆-螺母传动原理设计了密封盖启闭锁紧结构,通过对操作过程受力情况与密封方式分析,优化了传动结构、密封结构、壳体结构,保证了密封舱盖的操作便利性与密封性能.

The suction anchor hatch cover,as the main structural part of the suction anchor,is used for the discharge of gas and liquid in the process of the suction anchor sinking.This paper proposes a creative spiral elevating suction anchor seal hatch,based on the screw and nut transmission principle to design the structure of sealing cover opening and closing lock,by analyzing the operation process of stress distribution and sealing way,optimize the transmission structure,seal structure,shell structure,to ensure the sealing operation convenience and sealing performance of hatch covers.
