The invention provides an underwater fixed-point residing operation platform with a migration mode, which comprises a separable gravity bracket arranged at the bottom of an operation platform main body, and an underwater propelling device rotationally mounted on the operation platform; when the working platform main body is switched from the bottom-sitting state to the floating state, the underwater propelling device rotates to jet flow towards the gravity bracket and provides floating lift force for the working platform main body; or, the working platform main body throws the load of the gravity bracket, and the working platform main body floats upwards under the action of positive buoyancy; or, the working platform main body throws the load of the gravity bracket, and the underwater propulsion device provides floating lift force for the working platform main body. The working platform body is prevented from making contact with the seabed through the gravity support, the working platform body is prevented from sinking into the seabed, the underwater propelling device is used for jetting flow to the gravity support to blow away sludge on the gravity support, the problem that the gravity support is difficult to fall off due to sinking into the sludge is solved, upward lifting force can be provided in the sludge blowing-away process, and the working platform body is prevented from sinking into the seabed. The operation platform can be separated from the seabed.
本发明提供了一种具有迁徙模式的水下定点驻留作业平台,包括作业平台主体的底部设置有可分离的重力支架,作业平台上转动安装有水下推进装置;作业平台主体从坐底状态切换至上浮状态时:水下推进装置转动朝向重力支架喷流并为作业平台主体提供上浮升力;或,作业平台主体将重力支架抛载,作业平台主体在正浮力的作用下上浮;或,作业平台主体将重力支架抛载,水下推进装置为作业平台主体提供上浮升力。通过重力支架避免作业平台主体与海底接触,防止作业平台主体陷入海底,利用水下推进装置向重力支架喷流将重力支架处的淤泥吹除,减少重力支架陷入淤泥中难以脱出的问题,且在吹除淤泥的过程中,还能提供向上的升力,利于作业平台脱离海底。
