本发明涉及一种电缆锚固装置。
背景技术
随着海洋油气资源、海上风电等的不断开发建设，海缆作为信息和能量的传输渠道，在海上平台系统应用中越来越重要。在深海油气开发中，线缆常面临着干扰碰撞的风险，目前采用的有效手段是将多根电缆集束铰合在一起,在水下进行分支,该类电缆通常称为集束电缆。
针对上述集束电缆，其与浮式平台连接的锚固设计面临巨大考验。一是水深超过400m，在水中悬浮段电缆重量多达50吨；二是随着浮式平台和波流耦合运动，电缆受到的随机疲劳振动十分恶劣。传统的锚固设计只是对外层铠装进行加固，随着缆芯的增多和增重，该加固方式不能有效的锁住每个缆芯，并且安全工作载荷受到影响；如果只增加铠装层数，整个电缆的自重也会迅速增加，不利于进行锚固。
