Submarine cable fixing device with sealing and temporary clamping functions and fixing method

Abstract

The invention discloses a submarine cable fixing device with sealing and temporary clamping functions and a fixing method. The submarine cable fixing device comprises a protective tube, a connecting flange plate, a temporary clamp, a base plate, a pressing plate and an outer cover, wherein the connecting flange plate consists of two symmetrical half parts, the protective tube is arranged on the outer side of the protective tube, and the connecting flange plate is connected with the protective tube through bolts and nuts; the temporary clamp consists of two symmetrical half parts, and is mounted inside the connecting flange plate; the base plate consists of two symmetrical half parts, and is connected with the connecting flange plate through base plate bolts; the pressing plate consists of two symmetrical half parts, and is connected with the base plate through pressing plate bolts; and the outer cover consists of two symmetrical half parts, and is mounted at the position of a groove of the connecting flange plate. The fixing device disclosed by the invention integrally adopts a hover type symmetrical structure, and is convenient to mount; the temporary clamp adopts a special elastomer material, and can hold submarine cables tightly through extrusion with the submarine cables, so that the temporary clamping function for the submarine cables is realized, the device such as an independent temporary clamp or traction network cover does not need to be used, the cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to a submarine cable fixing device, in particular to a submarine cable fixing device and fixing method with sealing and temporary clamping functions, especially suitable for offshore wind turbines and oil platforms, and fixing the submarine cable at the port of the protection tube , sealing and other functions. Background technique [0002] With the depletion of land oil and other resources, people have turned their attention to the vast ocean, and the development of offshore oil and offshore wind power has also increased rapidly. As an important medium for offshore power transmission, submarine cables are crucial in the process of use and fixation. Due to the heavy gravity of the submarine cable itself, there will be a phenomenon of sliding. At present, the installation process on the platform needs to use a separate temporary clamp or traction net to temporarily fix the submarine cable, which brings inconvenience to the constru...

AI Technical Summary

Problems solved by technology

Due to the heavy gravity of the submarine cable itself, there will be a phenomenon of sliding. At present, the installation process on the platform needs to use a separate temporary clamp or traction net to temporarily fix the submarine cable, which brings inconvenience to the construction; on the other hand, due to the The dimensional tolerance of the cable or the fixing device will cause the submarine cable and the fixing device to be unable to be in close contact, and the sealant cannot be sealed. At present, the method of wrapping tape or wrapping a heat-shrinkable tube is often used, but some glue will still leak
