The invention discloses an underwater cable conveying device and method and a self-elevating double-floating-body offshore platform, and the underwater cable conveying device comprises a rack, and a cable drag chain, a protection device, a driving device, a drag chain fixed pulley block, a drag chain movable pulley block and a mounting rack which are arranged on the rack; the drag chain movable pulley block is mounted on the mounting frame and vertically corresponds to the drag chain fixed pulley block, one end of the cable drag chain sequentially and alternately bypasses pulleys on the drag chain movable pulley block and the drag chain fixed pulley block and is connected with the rack, and the other end of the cable drag chain vertically extends downwards and is connected with the lower floating body; the protection device is used for controlling the driving device to release the cable drag chain for protection and take back the protected and released cable drag chain when the drag force generated when the cable drag chain is impacted by seawater is larger than the braking force of the braking mechanism of the driving device. The underwater cable conveying device is high in safety and reliability.
本申请公开了一种水下电缆输送装置、输送方法及自升式双浮体海上平台,其中,水下电缆输送装置包括:机架以及设置在机架上的电缆拖链、保护装置、驱动装置、拖链定滑轮组、拖链动滑轮组和安装架;拖链动滑轮组安装在安装架上且与拖链定滑轮组上下对应排布,电缆拖链的一端依次交替绕过拖链动滑轮组与拖链定滑轮组上的各个滑轮且与机架连接,电缆拖链的另一端竖直向下延伸与下浮体连接;保护装置用于在电缆拖链受到海水冲击产生的拖动力大于驱动装置的制动机构的制动力时,控制驱动装置释放电缆拖链进行保护以及收回保护释放的电缆拖链。本申请的水下电缆输送装置,安全性和可靠性高。
