An umbrella-shaped self-starting pile pipe packer for marine engineering

Abstract

The invention discloses an umbrella-shaped self-starting pile pipe packer for marine engineering. The invention relates to the technical field of marine engineering. Its structure includes anchoring equipment. The top of the mechanism is fixedly connected with a locking device, the surface of the locking device is fixedly connected with a monitoring mechanism, the monitoring mechanism includes a mechanism wall, a built-in hole is opened at the lower position of the mechanism wall, and the upper position of the built-in hole is fixedly connected There is a cylinder, and a warping body is arranged at the inner side of the bottom of the mechanism wall. The umbrella-shaped self-starting marine engineering pile packer solves how to monitor the situation of the well wall in real time through the cooperative use of the monitoring mechanism, the scrubbing mechanism, the umbrella-shaped mechanism and the closing mechanism. It is difficult to remove the block by backwashing, and how to detect the working state of the sealing body to judge whether the sealing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an umbrella-shaped self-starting pile pipe packer for marine engineering. Background technique [0002] Pile tube packers are widely used in engineering fields with harsh environments such as offshore oil production platforms and wind power platforms. The existing domestic and foreign technical solutions all use annular hollow bottle plug type pile tube packers. This traditional packer structure It is: the outermost layer is a circular steel ring, the outer circle is welded on the inner wall of the jacket casing, the inner layer of the steel ring is cast and fixed with polyurethane with a central hole diameter, and the inner diameter of the central hole is slightly smaller than the outer diameter of the pile tube. The inner hole of the packer is an interference fit, which reduces the water plugging construction process of the oil well packer, can conveniently realize t...
