The invention provides an underwater fixed-point residence and migration dual-mode operation platform. The underwater fixed-point residence and migration dual-mode operation platform comprises a stage from a mother ship laying stage to a submarine diving stage, wherein the whole operation platform dives to a target position in water with negative buoyancy and resides; in the stage of switching from the residence mode to the migration mode, the underwater propelling device generates upward thrust, and after the whole working platform is lifted to a certain height from the seabed, the underwater propelling device generates forward thrust; in the cruising stage, the hydrofoils generate lift force due to the advancing navigational speed, and the negative buoyancy of the whole working platform in water is balanced for cruising. The hydrofoils can be folded and stored in the working platform body, when the hydrofoils do not need to generate lift force, the hydrofoils can be folded and stored in the working platform body, the underwater weight of the whole machine is not adjusted, and the lift force of the head section and the tail section in the migration process is used for resisting the underwater weight through thrust of the propelling device. The lift force in the migration process is used for resisting the underwater weight through the lift force of the hydrofoils, and the contradiction between resident fixed-point operation and long cruise migration operation is overcome.
本发明提供了一种水下定点驻留与迁徙的双模式作业平台,包括:从母船布放至下潜坐落海底阶段:利用作业平台整体在水中呈负浮力下潜至目标位置并驻留;驻留模式向迁徙模式切换阶段:水下推进装置产生向上的推力,作业平台整体从海底起升至一定高度后,水下推进装置产生向前的推力;巡航阶段:水翼因前进航速产生升力,平衡作业平台整体在水中的负浮力进行巡航。水翼为可折叠收入作业平台主体内,在不需要水翼产生升力时,可将水翼折叠收入作业平台主体内,实现了不调整整机水中重量,利用推进装置的推力实现迁徙过程首末段的升力对抗水下重量,利用水翼升力实现迁徙过程中段的升力对抗水下重量,克服了驻留定点作业和长巡航迁徙作业的矛盾。
