Intelligent plugging device for repairing seabed pipeline

Abstract

The invention provides an intelligent plugging device for repairing a seabed pipeline. The device comprises a pipe cleaner, a sealing locking mechanism, a connecting mechanism and a supporting movingmechanism, wherein the pipe cleaner is used for cleaning the pipe wall and impurities flowing in a pipe and supporting to push a plugging robot to move in and out of a pipeline; the supporting movingdevice is used for keeping uniform stressing and stable moving; the connecting mechanism is used for connecting through a ball hinge; the plugging device is adapted to corners with different curvaturein the pipeline based on the rotating property of a double-ball rod; the sealing locking mechanism is used for fixing , locking and sealing the position of the plugging device; the locking device cannot be designed into an integrally connected whole due to impurities, attaching matters, welding parts and various concave pits and bumps in the pipeline; a locking sliding block is composed of eightlocking claws which are uniformly distributed in the circumference. The device can accurately move to a broken part of the pipeline and remains extremely high sealing performance and can be used for performing cleaning, plugging, connecting and other projects on a broken oil conveying pipeline in the seabed.

Description

technical field [0001] The invention relates to an intelligent blocker for repairing submarine pipelines, which belongs to the technical field of marine equipment. Background technique [0002] As the number of human inhabitants on the earth grows faster and faster, the demand for resources is also increasing. In order to survive and develop, people began to march to the ocean. The most important resource in the ocean is oil. Due to the complexity and variability of the ocean environment, during the long-term service of the submarine petroleum gas pipeline, it is inevitable that the pipeline will be damaged due to tides, earthquakes, material defects, etc. The leakage of petroleum gas pollutes and destroys the marine ecological environment, and even endangers the personal safety of offshore operators, which will also bring great negative impacts to society. Therefore, in order to be able to complete the maintenance and sealing work of deep-sea submarine pipelines, it is nec...

Problems solved by technology

The pressure on the occluder should also be designed reasonably. In order to ensure its good sealing performance, two-stage occlusion is performed, because under higher pressure, the dynamic performance of the occluder becomes worse.
