Problems solved by technology

However, in actual use, it is found that if the ultra-high molecular weight polyethylene mooring rope is used under high temperature and long-lasting strength, the creep performance will not be very good, and the development of creep can lead to damage and aging failure of the fiber material, which limits Its long-term application in offshore mooring

Embodiment Construction

[0032] Such as figure 1 with figure 2 As shown, a mooring cable for underwater component devices in the sea is a skin-core composite double-layer structure; the inner cable core 1 is an 8-strand structure made of DM20 ultra-high molecular weight polyethylene, and the outer layer is wear-resistant high-strength polyester Fiber braided fixed sheath2.

[0033] The present invention is a method for manufacturing a mooring cable for a component device in sea water, the manufacturing process of which is as follows:

[0034] Step 1: The preparation method of the cable core with 8-strand structure is as follows:

[0035] a, make roving, choose 3 fineness DM20 ultra-high molecular weight polyethylene fibers and twist into roving by splicing machine;

[0036] B, system rope yarn, 7 synthetic rovings are twisted into rope yarn by twisting machine;

[0037] C, making rope strands, 3 synthetic rope yarns are twisted into rope strands by a strand making machine;

[0038] d, braiding, ...

Abstract

The invention relates to an offshore underwater component device mooring cable. The offshore underwater component device mooring cable is characterized by being of a sheath-core composite double-layer structure, an inner core is of a eight-strand structure made of DM20 ultra-high molecular weight polyethylene, an outer layer is a fixing sheath formed by weaving wear-proof high-strength polyester fibers, the inner core is formed according to the steps of manufacturing rough yarn, manufacturing rope yarn, manufacturing strands, weaving ropes, soaking the inner core in resin, prestretching the inner core and drying the inner core, and the fixing sheath is formed according to the steps of splicing threads, twisting the threads, manufacturing strands and weaving the 32 strands around the inner core into the fixing sheath in a one-off mode through a double-layer weaving machine.

Description

technical field [0001] The invention relates to a mooring cable for an underwater component device used at sea and a manufacturing method thereof. Background technique [0002] Offshore underwater component installations mainly refer to sea buoy berths, buoys, submersible buoys, navigation lights, underwater weapons (mines), etc. In the past, the mooring cables of these underwater component devices all adopted steel wire cables or anchor chains when they were in use. Now along with the expansion of the use range of the mooring cable system device and the increase of water depth, the mooring cable is lengthened, and the weight increases thereupon, and the buoyancy of the floating body cannot be supported. According to the situation in my country's sea area and the requirements of the navy and maritime (aircraft management) departments, it is impossible to use steel wire cables or anchor chains as mooring lines, and alternative materials are needed. [0003] In actual use, i...
