A pre-assembled joint-type submarine cable traction and anchoring integrated device

Abstract

The invention discloses a pre-assembling type jointed drawing and anchoring integrated device for submarine cables. The pre-assembling type jointed drawing and anchoring integrated device comprises a pipe opening, an anchoring base, connecting flanges, a flange, a cushioning plate and a plurality of connecting joints, wherein the connecting joints are connected in an end-to-end manner; the anchoring base is tightly clamped by the flange which is fixedly connected with the pipe opening simultaneously; the connecting joints are fixedly connected with the anchoring base by the connecting flanges; each connecting joint comprises a connecting shaft, a rear conical sleeve, a front conical sleeve and a bearing shaft; the bearing shafts are of spherical structures and are connected with the connecting flanges by threads; the connecting shafts are connected with the rear conical sleeves by threads; and the connecting shafts, the bearing shafts and the rear conical sleeves form a spherical structure with an untwisting function. The pre-assembling type jointed drawing and anchoring integrated device disclosed by the invention has the advantages that due to adoption of the drawing-head and anchoring integrated structure, the main-body part of the whole device is installed in a factory and the marine operation is not needed, so that the efficiency of marine construction is greatly improved.

Description

technical field [0001] The invention relates to a pre-assembled joint type submarine cable traction and anchoring integrated device, which is especially suitable for pulling the submarine cable through the pipeline to reach the platform and other positions when the submarine cable is laid. Background technique [0002] With the development of my country's offshore wind power generation and the vigorous exploitation of offshore oil, offshore construction has received more and more attention. Submarine cables are an important medium for offshore power transmission, and the laying, traction, and fixing of submarine cables are extremely important parts of offshore construction. At present, in the process of laying submarine cables, steel wire rope traction nets are generally used to fix the head of the submarine cable for traction. However, due to the heavy weight of the submarine cable itself, the long construction time, and the high platform height, the submarine cable is pron...

AI Technical Summary

Problems solved by technology

At present, in the process of laying submarine cables, steel wire rope traction nets are generally used to fix the head of the submarine cable for traction. However, due to the heavy weight of the submarine cable itself, the long construction time, and the high platform height, the submarine cable is prone to slipping and other phenomena. , and the traction net needs additional structures such as twisters, once the submarine cable slips or breaks, it will cause huge economic losses

In addition, the traditional traction method needs to be installed at sea, the installation process is cumbersome, and anchoring devices need to be installed at sea, which increases the difficulty of offshore construction
