Umbrella-shaped self-opening type ocean engineering pile pipe packer

Abstract

The invention discloses an umbrella-shaped self-opening type ocean engineering pile pipe packer, and relates to the technical field of ocean engineering. The umbrella-shaped self-opening type ocean engineering pile pipe packer structurally comprises anchoring equipment, wherein a closing mechanism is fixedly connected to the top of the anchoring equipment, locking equipment is fixedly connected to the top of the closing mechanism, and a monitoring mechanism is fixedly connected to the surface of the locking equipment. The monitoring mechanism comprises a mechanism wall, an air cylinder is fixedly connected to the inner side face of the mechanism wall, a warping body is arranged at the position, close to the inner side, of the bottom of the mechanism wall, and a washing mechanism is fixedly connected to the middle position of the surface of the mechanism wall. According to the umbrella-shaped self-opening type ocean engineering pile pipe packer, through cooperative use of the monitoring mechanism, the washing mechanism, an umbrella-shaped mechanism, the closing mechanism and other mechanisms, the problems that how to monitor the situation of a well wall in real time, sand blocks adhering to the well wall are difficult to remove through back washing, and how to detect the working state of a sealing body to judge whether the sealing effect is achieved or not are solved.

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...
