Each power cable unit 11 , control cable unit 12 , stainless steel optical fiber unit 13 and ground cable unit 14 may include a corresponding wire core 10 a and a sheath 10 b extruded outside the wire core 10 a.
本实施例中，所述铠装层40具有若干根铠装丝43，每一铠装丝43均可包括基体431以及设置在所述基体431外表面的耐磨层432，本实施方式中，所述耐磨层432可通过挤塑的方式设置在所述基体431外表面，耐磨层432可以提高脐带缆100在水下时的耐磨损和/或耐腐蚀能力，每一铠装丝43的外表面的耐磨层432能够更好地保护每一基体431，提高基体431的耐磨性。In this embodiment, the armored layer 40 has several armored wires 43, and each armored wire 43 can include a matrix 431 and a wear-resistant layer 432 arranged on the outer surface of the matrix 431. In this embodiment, The wear-resistant layer 432 can be disposed on the outer surface of the base 431 by extrusion, and the wear-resistant layer 432 can improve the wear resistance and/or corrosion resistance of the umbilical cable 100 when it is underwater. Each armored wire The wear-resistant layer 432 on the outer surface of 43 can better protect each matrix 431 and improve the wear resistance of the matrix 431.
本实施例中，所述基体431采用纤维增强复合材料制成，例如可以采用芳纶纤维增强复合材料制成，在制作时，将一定量的芳纶纤维纱、高分子聚合物基体、引发剂以及脱模剂成型芳纶纤维增强复合丝，铠装丝43绞合形成铠装层40。所述耐磨层432可以采用尼龙制成，例如尼龙1212，可以理解的是，所述耐磨层432还可以采用其他的材料制作。本实施方式，通过胶黏剂将铠装丝43绞合后，使得铠装层43结构紧凑、不松散，在一些情况下，可以去除在铠装层40所需的外耐磨层，制作更为简单，大大降低了产品成本。In this embodiment, the matrix 431 is made of fiber-reinforced composite material, for example, it can be made of aramid fiber-reinforced composite material. During production, a certain amount of aramid fiber yarn, polymer matrix, initiator And the aramid fiber-reinforced composite yarn formed by the release agent, and the armored yarn 43 is twisted to form the armored layer 40 . The wear-resistant layer 432 can be made of nylon, such as nylon 1212. It can be understood that the wear-resistant layer 432 can also be made of other materials. In this embodiment, after the armored wire 43 is twisted by an adhesive, the armored layer 43 has a compact structure and is not loose. In some cases, the outer wear-resistant layer required by the armored layer 40 can be removed to make a more durable For simplicity, the product cost is greatly reduced.
通过纤维增强复合材料的非金属铠装丝43进行铠装而作为脐带缆100的承力元件，与钢丝相比，在同等外径、抗拉强度的情况下，非金属铠装丝43的比重仅为钢丝比重的1/4，具有比重低、强度高的优点，能够大大降低脐带缆在水中的静载荷，提高脐带缆强度/水下静载荷比，能够满足更深的水下生产和作业，可以满足于11000m水深的ROV使用要求。The non-metallic armored wire 43 of fiber-reinforced composite material is used as the load-bearing element of the umbilical cable 100 for armoring. Compared with the steel wire, in the case of the same outer diameter and tensile strength, the specific gravity of the non-metallic armored wire 43 is Only 1/4 of the specific gravity of steel wire, it has the advantages of low specific gravity and high strength, which can greatly reduce the static load of the umbilical cable in water, improve the strength of the umbilical cable to the underwater static load ratio, and can meet deeper underwater production and operations. It can meet the requirements of ROV with a water depth of 11000m.
所述铠装层40可以为一层或者多层，当所述铠装层40包括多层时，相邻两层铠装层40之间的绞合方向相反。本实施方式中，所述铠装层40可以包括两层，分别为绞合在所述内护层30外的内铠装层41和绞合在所述内铠装层41外的外铠装层42。The armor layer 40 may be one or more layers, and when the armor layer 40 includes multiple layers, the stranding directions between two adjacent armor layers 40 are opposite. In this embodiment, the armor layer 40 may include two layers, namely an inner armor layer 41 twisted outside the inner sheath 30 and an outer armor twisted outside the inner armor layer 41. Layer 42.
所述内铠装层41的铠装丝43直径d1大于所述外铠装层42的铠装丝43的直径d2，随着脐带缆的直径的增大，设置在最外层的外铠装层42的铠装丝43采用更小的直径，能够更加紧凑地绞合在内铠装层41的外表面上，能够让铠装层41的铠装效果更好，让脐带缆100的强度更大。The diameter d1 of the armored wire 43 of the inner armor layer 41 is larger than the diameter d2 of the armored wire 43 of the outer armor layer 42, and as the diameter of the umbilical cable increases, the outer armor disposed on the outermost layer The armor wire 43 of the layer 42 adopts a smaller diameter, which can be twisted more compactly on the outer surface of the inner armor layer 41, which can make the armor effect of the armor layer 41 better and make the umbilical cable 100 stronger. big.
所述外护层50可以采用聚氨酯编织带编织而成，外护层50将铠装层仅仅包括所述铠装层40。现有的外护层一般由沥青和聚丙烯绳组成，在生成外护层过程中，需要对沥青和聚丙烯绳进行加热，而加热会对纤维增强复合材料制成的非金属铠装丝造成损伤，不适用于纤维增强复合材料的非金属铠装的脐带缆。而且，现有的外护层无法满足脐带缆反复收放的使用要求，采用聚氨酯编织带编织而成的外护层工艺简单，不会对纤维增强复合材料的非金属铠装造成损伤，并且具有优越的耐磨性能，聚氨酯编织带编织而成的外护层可以将铠装层与导轮进行隔离，耐磨性能好，避免导轮直接与铠装层接触，保证脐带缆的强度，大大提高了脐带缆的使用寿命。The outer sheath 50 can be braided by polyurethane braid, and the outer sheath 50 includes only the armor layer 40 as the armor layer. The existing outer sheath is generally composed of asphalt and polypropylene ropes. During the process of forming the outer sheath, the asphalt and polypropylene ropes need to be heated, and the heating will cause damage to the non-metallic armor wires made of fiber-reinforced composite materials. Damage, not applicable to non-metallic armored umbilical cables of fiber reinforced composite materials. Moreover, the existing outer sheath cannot meet the requirements of repeated retraction and deployment of the umbilical cable. The outer sheath made of polyurethane braid has a simple process and will not cause damage to the non-metallic armor of the fiber-reinforced composite material, and has Excellent wear resistance, the outer sheath made of polyurethane braid can isolate the armor layer from the guide wheel, has good wear resistance, prevents the guide wheel from directly contacting the armor layer, ensures the strength of the umbilical cable, and greatly improves the service life of the umbilical cord.
