Pipeline erecting device used for ocean engineering

Abstract

The invention discloses a pipeline erecting device used for ocean engineering, and relates to the technical field of ocean engineering. The pipeline erecting device used for ocean engineering comprises a bottom plate, wherein the bottom plate comprises a flat plate and a columnar shell vertically distributed on the flat plate; two sets of connecting seats I are fixed onto the flat plate, and the connecting seats I and the columnar shell are distributed oppositely; a corresponding fixing arm is rotatably installed on each set of connecting seat I, telescopic assemblies are further installed on the flat plate, and the telescopic assemblies are connected with the fixing arms through connecting plates; a water inlet part is further installed on the side surface, provided with the columnar shell, of the flat plate; and the water inlet part comprises a square pipe, rotating parts and a partition plate, the columnar shell is sleeved with the partition plate arranged in the square pipe, groove holes which communicate with channels of the square pipe are formed in the columnar shell, and the rotating parts are rotatably installed in the groove holes. According to the pipeline erecting device used for ocean engineering, trumpet-shaped openings are formed in end portions of the water inlet part, and undercurrent of seabed can conveniently drive the installed rotating parts through the openings, so that water in the columnar shell is discharged, and the columnar shell is adsorbed to the seabed.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, in particular to a pipeline erection device for marine engineering. Background technique [0002] Submarine pipeline erection is an important part of ocean engineering today. There are two main laying methods for submarine pipelines: one is the pipe dragging method, and the other is the pipe laying ship method. Sea and very shallow waters or short-distance sea pipes are laid offshore. [0003] The existing support equipment for submarine pipelines is mostly fixed with the seabed by brackets, so as to support the pipelines. However, during the long-term use of effective submarine pipeline supports, they are impacted by undercurrents on the seabed, which makes the submarine pipeline supports loose, thus failing to perform well. When encountering a large undercurrent, the subsea pipeline support will be impacted and separated from the seabed, which will damage part of the subsea pipeline...

[0003] The existing support equipment for submarine pipelines is mostly fixed with the seabed by brackets, so as to support the pipelines. However, during the long-term use of effective submarine pipeline supports, they are impacted by undercurrents on the seabed, which makes the submarine pipeline supports loose, thus failing to perform well. When encountering a large undercurrent, the subsea pipeline support will be impacted and separated from the seabed, which will damage part of the subsea pipeline, thus affecting the use. Moreover, the existing subsea pipeline support has cumbersome fixing steps and needs to be fixed by multiple parts. Moreover, as the use time increases, the fixed parts will become loose, causing the pipeline to shake when it encounters an undercurrent, reducing the service life of the pipeline
