The invention belongs to the technical field of underwater salvage, and discloses an underwater stage-by-stage inflating and stage-by-stage lifting salvage system and a salvage method thereof. The system comprises a salvage ship, a recovery device, a step-by-step lifting device, a fixing device and a buoyancy pipe, and the recovery device is arranged on the salvage ship; one end of the step-by-step lifting device is fixedly connected with the recovery device, and the other end is fixedly connected with the fixing device; and the buoyancy pipe is placed in the salvage ship. And the air compression device is arranged in front of the recovery device. The device is simple in structure, convenient to mount, dismount and combine, easy to operate and high in practicability; high-difficulty deep water salvage is achieved through low-difficulty shallow water inflation, the operation method is simple and easy to implement, the technical difficulty of water drainage and gas injection in a deep water area is effectively avoided while operation is easy and convenient, realizability of deep water objects and ultra-deep water objects is ensured, and the salvage efficiency is improved. And meanwhile, fishing of deep-water large and ultra-large objects is realizable through cooperation of equipment.

    本发明属于水下打捞技术领域,公开了一种水下逐级充气逐级提升打捞系统及其打捞方法。该系统包括打捞船,回收装置、逐级提升装置、固定装置和浮力管,其中,回收装置设置在打捞船上;逐级提升装置一端与回收装置固定连接,另一端与固定装置固定连接;浮力管放置在打捞船内。还包括设置在回收装置前方的空气压缩装置。本发明的结构简单,便于安装、拆卸和组合,易于操作,实用性强;且本发明通过低难度的浅水充气、实现高难度深水打捞,操作方法简单,易于实现,在操作简便的同时有效避免了在深水区排水和注气的技术难度,确保深水物体、超深水物体可实现性,同时通过设备的配合对深水大型、超大型物体打捞可实现性。
