Description

一种自发光易辩识线缆及其制造方法 技术领域
[0001] 本发明属于光、 电缆及电力、 通信施工技术领域, 尤其是涉及一种自发光易辩 识线缆及其制造方法。
背景技术
[0002] 随着通信行业的飞速发展, 光纤光缆、 电线电缆的应用日益广泛, 现有技术中 线缆在室外的应用主要有: 管道、 地埋、 架空三种方式; 由于线缆分属不同的 业主, 但它们可能同管、 同杆敷设, 这种情况下, 给维护、 维修人员带来了极 大的不便, 由于线缆表面的印字会随吋间的推移逐渐腿色, 因此, 维护、 维修 人员极难在短吋间准确找到要维护及维修的线缆, 尤其是在夜晚或光线极暗的 场合。 为此, 国内对于该方面作出了大量的研究, 主要的文献如下。
[0003] CN202615012U公幵了防枪击夜视光缆, 包括缆芯 1和包裹缆芯 1的内护套 2, 所 述的缆芯 1包括光纤单元 3和设置在光纤单元 3周围的加强件 4, 所述的加强件 4围 绕光纤单元 3绞合成紧凑的圆形, 所述的光纤单元 3包括一根光纤 6和包裹光纤 6 的松套管 5, 所述的内护套 2的外壁上连续分布有沿着光缆延伸方向的缺口 7, 内 护套 2的外部还包裹有外护套 8, 外护套 8上还设置有夜晚发光色条 9。
[0004] CN105717596A公幵了一种可夜视识别的自承式架空光缆, 其特征在于: 包括 缆芯、 包覆住缆芯的外护套、 由单根钢丝或玻璃纤维增强塑料制成的增强元件 、 包覆住增强元件的吊线护层、 连接吊线护层与外护套的筋; 所述缆芯由位于 中央的中心加强件、 位于中心加强件之外的多根松套管、 包覆住多根松套管的 保护层构成; 松套管中具有至少一根光导纤维; 吊线护层上对称地设有两根标 识条, 所述相同材料的吊线护层、 外护套、 筋是一体成形; 所述标识条是由以 下重量份的原料构成的: 低密度聚乙烯或中密度聚乙烯或高密度聚乙烯或低烟 无卤阻燃聚乙烯 90份、 聚乙烯色母料 2份、 钛白粉 6份、 抗氧化剂 0.3份、 天然石 蜡 1.7份。
[0005] CN103048758A公幵了一种夜视光缆; 它包含有缆芯、 包覆在缆芯上的保护层 、 挤塑在保护层上的外护套; 其特征在于外护套上形成有至少一根颜色异于外 护套颜色的标识条, 标识条是与外护套结合为一体的, 在光缆的任一横截面上 , 标识条的外边缘与外护套的外边缘在同一个圆周上, 标识条的内边缘为圆弧 且其圆心与外护套外边缘的圆心、 外护套内边缘的圆心是重合的; 所述标识条 可以发光; 标识条中包含有以下原材料: ①与外护套具有相同的主体材料; ②市 售聚乙烯色母料; ③注塑专用夜光粉: ④夜光增强添加粉。 本发明具有便于识别 、 便于施工、 便于夜间抢修及维护的等有益效果; 夜间也能被非常清晰地识别
[0006] 简言之, 上述的方案是在光缆护套上挤塑标识条, 当然标识条可能具有夜光及 亮光识别的功能, 但是, 这种方式存在以下主要的缺陷: (1) 需要多色机头, 或多种模具, 同吋挤塑或注塑, 这种方式不仅加大了机器设备的投入, 而且会 使用较多的场地, 标识条与护套层的结合力也会随着吋间的推移变小、 抗扭能 力相对较差; (2) 各种色条、 模具的管理比较麻烦, 不同的外径, 需要不同的 分色模具或护套挤出模具, 造成了成本的增加。
[0007] CN204595274U公幵了一种通信用发光光缆, 它包含有光缆缆芯、 包覆在光缆 缆芯外的保护层、 挤塑包覆在保护层外的内护层, 光缆缆芯由位于中央的加强 件、 以平行或绞合的方式分布在加强件外的多根松套管、 将多根松套管包扎住 的包扎层构成, 每根松套管中至少具有一根光导纤维; 其特征在于所述内护层 的外缘具有多个向内护层内缘方向凹陷的凹槽, 凹槽中具有发光层, 内护层的 外缘不具有凹槽处、 发光层外缘位于同一圆柱面上, 内护层、 发光层外挤塑包 覆有防护层; 发光层是与内护层一起挤塑嵌入在凹槽中的; 防护层是透明的。 该发光层同样也是挤塑形成的, 光缆或电缆的直径不同, 内护层的挤塑模具就 会不同, 这样, 挤塑的发光层的模具及厚度、 宽度也不一样。
[0008] 上述方式, 都给制造厂商带来了极大的麻烦。
[0009] 另一方面, 大部分的稀土材料具有受光发光的特性, 其元素具有特殊的电子层 结构, 外层电子受激发后, 从基态跃迁至激发态, 再从激发态回到基态的过程 中以光的形式释放能量; 所以, 大部分的稀土发光材料只要吸收任何可见光 5分 钟, 便能在黑暗状态下持续发光 10小吋以上, 并可循环使用, 无毒, 无害, 无 放射性, 寿命达 200年左右。
技术问题
[0010] 线缆表面的印字会随吋间的推移逐渐腿色, 因此, 维护、 维修人员极难在短吋 间准确找到要维护及维修的线缆, 尤其是在夜晚或光线极暗的场合。
