Description

海缆水压测试舱

技术领域
本发明涉及海缆测试技术领域，具体涉及一种海缆水压测试舱。
背景技术
随着离岸基础设施投资、海底勘探、深水区油田开发，海洋工业经济正在蓬勃发展起来。海底光电复合海缆作为发挥电力和通讯系统功能的纽带，起着举足轻重的重用。
跨洲际高压电缆和通讯光缆动辄铺设在深达3000m以上的超深水环境中，深水光电复合海缆结构常采用多层铠装、挤出较厚的PE护套进行功能单元(导体、光纤)的防护。深海光电复合海缆设计完毕，需要进行高水压环境模拟测试。
常规的海缆水压舱，将整段缆浸泡在密封舱内，来验证海缆的径向压缩和纵向透水性能。然而这种测试方法，只能验证海缆单一性能，不能验证海缆在深水环境下的光电传输性能。
在水压舱中，光电复合海缆两端需要露出，进行光、电性能的在线监测，同时在光电复合海缆露出端需要进行密封处理。然而，在舱内施加1.5倍的环境工作水压，由于缆在舱内、舱外受到的压力不一致，在高水压侧容易造成电缆PE护套凹痕和剥离的现象，由于两端压差悬殊，露出的缆头在密封位置，往往会被压缩变形，影响测试的效果。
发明内容
因此，本发明要解决的技术问题在于克服现有技术中的水压仓容易使 露出的缆头剥离的缺陷，从而提供一种能够降低海缆露出部分与舱内部分压差的海缆水压测试舱。
为了解决上述技术问题，本发明提供一种海缆水压测试舱，包括：
壳体，所述壳体上具有海缆进口和海缆出口，当海缆穿过所述壳体后，所述海缆的两端分别伸出所述海缆进口和所述海缆出口；
所述壳体内具有依次设置的至少三个压力仓，在每个所述压力仓上分别设置有测压装置；
所述壳体内，在相邻两个所述压力仓之间具有用于穿过海缆的通道，当所述海缆穿过该通道后，相邻两个所述压力仓之间进行封闭。
可选地，多个所述压力仓之间通过法兰连接。
可选地，相邻两个所述压力仓之间的通道通过填料与海缆配合密封。
可选地，相邻两个所述压力仓之间具有隔板，所述隔板上具有套孔，所述填料容纳在所述套孔内。
可选地，所述套孔外设置压盖，所述压盖与所述隔板之间通过紧固件连接。
可选地，所述压盖的用于贴紧所述隔板的平面上，与所述隔板之间设置有密封圈。

可选地，所述壳体的相邻两段之间的法兰面上设置有密封圈。
可选地，所述密封圈具有至少两圈。
本发明技术方案，具有如下优点：
本发明提供的海缆水压测试舱，当海缆穿过壳体后，使壳体内的三个压力仓之间相对密封，其中，位于中间的压力仓可用于对海缆进行压力测试，而位于两侧的压力仓可用于缓冲对海缆进行测试的压力仓与外界之间的压差，从而降低海缆露出的缆头剥离的问题。
