Carbon fiber umbilical cable terminal connecting device

Abstract

The invention belongs to the field of ocean engineering, and particularly relates to a carbon fiber umbilical cable terminal connecting device, which comprises a flange pipe, a flange sleeve and a split-phase flange plate which are detachably connected in sequence from front to back. The flange pipe comprises a first flange pipe split body and a second flange pipe split body which are detachably connected, and a pipe cavity used for limiting a cable pipe can be formed when the first flange pipe split body and the second flange pipe split body are combined. A sleeve cavity of the flange sleeve is used for accommodating dispersed sub-cables; and the split-phase flange plate is used for covering a sleeve cavity of the flange sleeve, a plurality of through holes for the sub-cables to penetrate out are formed in the split-phase flange plate, the split-phase flange plate is further detachably connected with a plurality of fastening assemblies, and the fastening assemblies are located on the rear sides of the corresponding through holes and used for limiting and fixing the sub-cables. The umbilical cable is reasonable in structural design, the problem of underwater sealing connection of all functional units of the umbilical cable is solved, the fixing mode of the umbilical cable and an underwater terminal is optimized, higher axial bearing capacity is provided, and good mechanical performance is provided.

Description

technical field [0001] The invention belongs to the field of ocean engineering, and in particular relates to a carbon fiber umbilical cable terminal connection device. Background technique [0002] Umbilical cables are widely used in the development and application of deep sea oil and gas. As an important device that connects the underwater production system and the floating platform, it provides hydraulic power, electric power, chemical agents, remote control and monitoring data transmission for the underwater production system. Such as figure 1 As shown, the umbilical cable 1 includes a cable tube 100 and a sub-cable 101, and the sub-cable includes a functional unit sub-cable and a carbon fiber unit sub-cable. [0003] The connection between multiple functional units of the umbilical cable and the underwater distribution unit requires good underwater sealing performance, and at the same time, it needs to be fixed with the terminal and cannot be separated. However, the e...

AI Technical Summary

Problems solved by technology

However, the existing underwater terminal connection devices have the following problems: 1. The axial bearing capacity is not enough, and the armored steel wire will fail to pull off when applied to deep sea; 2. Most of them are monolithic, which is difficult to process and the assembly process is complicated; 3. There is less sealing for the phase separation unit
