The invention relates to the technical field of trunks, and discloses a self-elevating platform trunk structure for reducing resistance, which comprises a trunk arranged at the bottom of a ship body and a pile shoe arranged in the trunk, the trunk comprises a trunk tail end, a trunk bow end and a trunk top end, the trunk top end is connected with the pile shoe, a guide plate is connected between the trunk tail end and a ship bottom plate, and the guide plate is connected with the trunk bow end. The guide plate is downwards obliquely arranged from the tail end of the trunk to be connected with the ship bottom plate, and an arc transition plate is arranged between the guide plate and the ship bottom plate. The device is provided with the flow guide plate, fluid entering the trunk along the surface of the ship bottom and flowing to the flow guide plate along the pile shoe bottom plate can be divided into two directions on the flow guide plate, the impact force caused by the fact that the fluid directly impacts the trunk tail plate is avoided in a flow guide mode, and the sailing resistance of the platform is greatly reduced; the transition of the ship bottom plate of fluid is smoother, the stress of the ship bottom plate structure is more uniform, and the stress concentration phenomenon is effectively relieved.
本发明涉及围井技术领域,公开了一种自升式平台降低阻力的围井结构,包括设于船体底部的围井以及设于围井内的桩靴,所述围井包括围井尾端、围井艏端、围井顶端,所述围井顶端连接桩靴,围井尾端与船底板之间连接设置导流板,导流板自围井尾端向下斜向设置连接船底板,导流板与船底板之间设有圆弧过渡板。本发明装置设置导流板,能使沿着船底表面进入围井,沿着桩靴底板一直流向导流板的流体,在导流板上分成2个方向,通过导流方式,避免流体直接冲击围井尾板带来的冲击力,大大减少了平台的航行阻力,且通过设置圆弧过渡板,使流体的船底板过渡更加流畅,使船底板结构受力更加均匀,有效的缓解了应力集中现象。
