Submarine Cable Joint Clamping Structure for Hoisting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Submarine cable joints are prone to damage during installation and hoisting due to relative transfer and deformation of the submarine cable joint box, which is typically a hollow, closed shell structure covering the joint.
Innovation Solution
A submarine cable joint protection apparatus comprising an outer shell and a reinforcement assembly with pads and mounting grooves that clamp and isolate the joints, preventing movement and deformation during installation and hoisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hollow closed shell structure is used to cover the submarine cable joint, then the joint is protected from external forces such as ocean currents and marine life, but the joint may undergo relative transfer and deformation during installation and hoisting due to the transfer of the joint box
Solution Approach 1:
The inner shell is divided into multiple segments that can be independently adjusted. Each segment can be positioned and fixed separately to match the outer shell, allowing the joint to be securely held in place while accommodating any relative transfer or deformation during installation and hoisting operations.
Solution Approach 2:
The inner shell is designed with adjustable and movable segments rather than a fixed rigid structure. This dynamic design allows the inner shell to adapt to position changes of the joint during transfer, maintaining stable support and preventing deformation while still providing protection from external forces.
2Ease of manufacture
If the submarine cable joint box is installed outside the joint after setting is completed, then the joint can be protected, but the transfer of the joint box causes relative transfer and deformation of the internal joint
Solution Approach 1:
The inner shell segments are pre-configured with adjustment mechanisms that allow for precise positioning of the joint before the outer shell is fully assembled. This preliminary action ensures the joint is securely positioned and protected from deformation during the subsequent installation and hoisting processes.
Solution Approach 2:
The adjustable inner shell segments act as an intermediary between the joint and the outer shell. These segments can be fine-tuned to precisely position the joint, eliminating relative transfer and deformation while still allowing the outer shell to provide protective coverage during installation.
