Inflatable packer based on undersea pile leg
The invention discloses an inflatable packer based on an undersea pile leg and belongs to the technical field of marine equipment. The packer comprises the hollow columnar pile leg (2), a plurality of guide blocks (3) uniformly distributed on the periphery of the upper part in the pile leg, an inflatable bag module located below the guide blocks and attached to the periphery of the inner wall of the pile leg, and an annular mud-preventing ring component placed under the inflatable bag module and used for fixing a jacket sleeve (1) lifted into the pile leg (2). Compared with the prior art, the inflatable packer has the beneficial effects as follows: the inflatable packer causes no damage to the jacket sleeve and improves the safety performance of a jacket; and the packer is connected with the pile leg into a whole, thereby being compact in structure, having controllable sealing pressure, causing little damage to the jacket and ensuring safe operating and sealing processes.
