The deep-sea unpowered autonomous burying bottom-sitting device comprises a bottom-sitting rod, a cylindrical flow channel is arranged in the bottom-sitting rod, four axisymmetric horizontal flow channels are arranged on the periphery of the upper portion of the bottom-sitting rod, and the horizontal flow channels communicate with the cylindrical flow channel; a limiting boss assembly is installed outside the bottom-sitting rod and divided into an upper limiting boss and a lower limiting boss, the upper limiting boss and the lower limiting boss are oppositely arranged in an up-down spaced mode, a piston assembly is installed in the cylindrical flow channel, and a sliding assembly is installed on the bottom-sitting rod between the upper limiting boss and the lower limiting boss in a matched mode. A rotating assembly is installed outside the sliding assembly. The propeller absorbs ocean current force to serve as power input, intermittent suction operation of seabed sludge at the bottom of the supporting rod is achieved through self-adaptive deformation of blades, repeated lifting of the propeller is maintained, and the design of a piston, a one-way valve and a flow channel in the supporting rod is combined, and the node supporting rod is promoted to be gradually inserted into the seabed till being completely buried.

    一种深海无动力自主掩埋的坐底装置及操作方法,包括坐底杆,其内部设置圆柱流道,位于坐底杆上方四周设置有四个轴对称的水平流道,水平流道与圆柱流道连通;坐底杆的外部安装有限位凸台组件,限位凸台组件分为上限位凸台和下限位凸台,上限位凸台和下限位凸台上下间隔相对布置,圆柱流道内部安装有活塞组件,位于上限位凸台和下限位凸台之间的坐底杆上配合安装有滑动组件,滑动组件的外部安装有转动组件。以螺旋桨吸收海流力作为动力输入,通过桨叶的自适应性变形,维持螺旋桨反复升降,结合活塞、单向阀和支杆内流道的设计,实现对支杆底部海底淤泥的间歇抽吸作业,促使节点支杆的逐步插入海底,直至完全掩埋。
