Description

具有光纤通信和监测功能的复合型油气软管 技术领域
本发明涉及油气输送管道领域，具体是涉及一种具有光纤通信和监测功能的复合型油气软管。
背景技术
石油和天然气输运与国民经济和人民生活息息相关，为保障油气管道的输运安全，需要对油气管道实施监控。目前，国际上发展了多种用于油气管道的监测技术。随着光通信技术的迅猛发展，特别是光纤通信和光纤传感监测技术在各行业的广泛应用，光纤传感监测技术也大量应用于油气管道的监测。现有的光纤传感监测技术都是沿着管道外表面单独地敷设一根光缆，额外地增加了工程造价成本。并且，由于光缆直接敷设在管道的外表面，极易受到外部干扰的影响，导致监测系统的灵敏度和准确性不高。
发明内容
本发明的目的是为了克服上述背景技术的不足，提供一种具有光纤通信和监测功能的复合型油气软管，该复合型油气软管的内部集成有光缆，不仅满足了光纤通信和监测功能，同时降低了工程造价成本。此外，由于光缆位于油气软管内部，不易受到外部干扰的影响，因此能够快速准确地监测油气软管的实时状态，提高监测系统的灵敏度和准确性。
本发明提供一种具有光纤通信和监测功能的复合型油气软管，包括金属软管，金属软管外设置有用于保护金属软管的内护套，所述 内护套外紧密环绕有若干根扁型钢带，其中一根扁型钢带内布置有光缆，若干根扁型钢带的外部整体包覆有外护套；该复合型油气软管同时具备光纤通信和监测功能。
在上述技术方案的基础上，所述若干根扁形钢带在内护套外环绕有两层，其中一层的所有扁形钢带沿顺时针方向排列，另一层的所有扁形钢带沿逆时针方向排列。
在上述技术方案的基础上，紧贴着内护套的一层扁形钢带中，有一根扁型钢带内部开有线槽，线槽轴向贯穿这一根扁型钢带，线槽的纵截面呈正弦形；线槽内布置有光缆。
在上述技术方案的基础上，所述金属软管由若干环扣型钢带组成，每个环扣型钢带的横截面呈圆环形，且圆环的边沿设置有卡扣，每相邻的两个环扣型钢带之间通过卡扣紧密卡接。
在上述技术方案的基础上，所述环扣型钢带采用不锈钢制成，厚度为2～5mm。
在上述技术方案的基础上，所述光缆是耐高温耐氢损光缆，光缆包括光纤，光纤为耐高温耐氢损光纤。
在上述技术方案的基础上，所述光纤外铠装有不锈钢钢管或螺旋钢带；当采用螺旋钢带对光纤进行铠装时，螺旋钢带外包覆有耐高温护套。
在上述技术方案的基础上，所述耐高温耐氢损光纤为紫外光固化光纤或者紧套光纤，紫外光固化光纤的涂层材料为耐高温涂料，紧套光纤外层的紧套材料为耐高温材料。
在上述技术方案的基础上，所述耐高温涂料为耐高温的丙烯酸树脂，所述耐高温材料为氟塑料、聚醚醚酮。
在上述技术方案的基础上，所述内护套、外护套采用高密度聚 乙烯，通过挤塑机挤出成型的方式制成。
与现有技术相比，本发明的优点如下：
1、本发明在油气软管的内部集成了光缆，得到同时具有光纤通信和监测功能的复合型油气软管。由于光缆位于油气软管内部，不易受到外部干扰的影响，因此能够快速准确地监测油气软管的实时状态，提高监测系统的灵敏度和准确性。
2、该光缆位于油气软管内部的扁型钢带中，且呈正弦型布置，因此，光缆的总长度大于扁型钢带的总长度；当油气软管在安装过程中受外部作用力发生弯曲时，由于光缆具有一定的余长，可以保证光缆中的光纤不受影响。
3、传统的油气管道如钢管、水泥管等，由于单根管道的长度有限，一般小于30米，因此，长距离布放时，使用的管道数量较多，管道接头也较多，不仅安装施工较复杂，而且工程造价成本高。本发明中的金属软管采用若干环扣型钢带一节一节地连续卡接而成，有效保证了油气软管的强度和柔韧性；该油气软管生产加工方便，并且单根管道的连续长度可达1000米，长距离布放时，使用的油气软管数量较少，管道接头也较少；该油气软管的安装施工较简便，可以直接安装在地下，管道或者桥架上，极大节约了工程造价成本。
