Laminated self-adjusting packer
The invention belongs to the field of installation of offshore jackets, and particularly relates to a laminated self-adjusting packer which is characterized in that two packing plate groups are arranged up and down, a self-expansion device capable of automatically expanding when encountering water is arranged between the two packing plate groups, and each packing plate group comprises at least three packing plates arranged on a sleeve in a sleeving manner; the sealing partition plates are adjusted in a relative sliding mode in the radial direction along with the change of the distance between the outer wall of the sleeve and the inner surface of the steel pile in the falling process that the sleeve is sleeved with the steel pile. The uppermost layer of sealing partition plate in the upper sealing partition plate set is fixedly connected to the outer wall of the sleeve, the lowermost layer of sealing partition plate is a middle layer of sealing partition plate, the uppermost layer of sealing partition plate in the lower sealing partition plate set is a middle layer of sealing partition plate, the lowermost layer of sealing partition plate is fixedly connected to the outer wall of the sleeve, and the two middle layer of sealing partition plates are connected. The self-expansion device is arranged on the outer side of the joint of the two middle layer sealing partition plates in a sleeving mode. And the lower part of the lower sealing partition plate group is linked with an assembly. The pile deviation condition can be well dealt with, falling of the sleeve is not affected, and the plugging effect is guaranteed.
本发明属于海上导管架安装领域，具体地说是一种叠层式自调节封隔器，封隔板组为上下设置的两组，两组封隔板组之间设有遇水自膨胀的自膨胀装置，封隔板组包括至少三个套设在套筒上的封隔板，各封隔板之间在套筒向钢桩内套装的下落过程中随套筒外壁与钢桩内表面之间间距变化而沿径向相对滑动调节；上方封隔板组中最上层的封隔板固接于套筒外壁上、最下层的封隔板为中间层封隔板，下方封隔板组中最上层的封隔板为中间层封隔板、最下层的封隔板固接于套筒外壁上，两个中间层封隔板之间相连，自膨胀装置套设于两个中间层封隔板连接处的外侧；位于下方的封隔板组的下方连动有组件。本发明能够很好地应对偏桩情况，不会影响套筒下落，保证封堵效果。
