Description

Technical Field

[0001] This utility model relates to the technical field of subsea pipeline repair and splicing aids, and in particular to a subsea pipeline repair and splicing aid with an anti-corrosion coating. Background Technology

[0002] Corrosion-resistant subsea pipelines are used to transport materials in marine environments. Their design incorporates corrosion resistance to ensure they are not corroded by seawater or other natural factors during long-term use. Repair and splicing aids are devices used to help restore pipeline function when damage occurs. By assisting with installation and connection, they ensure the integrity and stability of the pipeline. This equipment plays a crucial role in marine environments, especially in complex subsea operations, where it improves the efficiency of pipeline repair and maintenance.

[0003] Traditional subsea pipeline repair and splicing aids typically consist of multiple adjustable connecting components, support devices, and clamps. These components, through precise design, enable the reconnection or repair of damaged subsea pipelines, ensuring the tightness and stability of the pipeline connections. The aid's role is to provide the necessary support and positioning for the subsea pipeline, enabling successful repair and restoration of its normal function.

[0004] Traditional subsea pipeline repair splicing aids cannot be height-adjusted, primarily because their design is mostly fixed, failing to allow for flexible height adjustments to meet varying repair needs. This fixed design limits the aid's adaptability in certain specialized repair environments, making it impossible to precisely connect the pipeline or adjust it to the optimal position during subsea pipeline repairs. The inability to adjust the height affects the accuracy and efficiency of the repair, increases operational difficulty, and can even lead to incomplete or unstable connections during the repair process, thus impacting the long-term safety of the pipeline. Utility Model Content

[0039] Reference Figure 4 and Figure 5 The fixing assembly includes multiple clamps 15, which are disposed on the top of the repair table 1. Multiple cylinders 9 are fixedly connected to the top of the repair table 1. Each cylinder 9 has a pusher 10 fixedly connected to its output end.

The hanging platform 6 at the bottom of the slider 5 moves synchronously, pushing the rotating frame 7 to rotate around the connecting column 8. Since the connecting column 8 is fixed between the support columns 2, the rotation of the rotating frame 7 drives the repair platform 1 to rise and fall, realizing flexible height adjustment to adapt to the height requirements of different subsea pipeline repairs. The cylinder 9 pushes the push platform 10 to adjust its position. The motor 16 drives the output wheel 17 to rotate. The arc-shaped sliding groove 18 of the output wheel 17 drives the sliding shaft 20 to slide. The sliding shaft 20 pulls the sliding table 12 through the fixing part 19. The side platforms 13 on both sides of the sliding table 12 move along the horizontal groove 11 of the push platform 10. The fixing frame 14 on the sliding table 12 drives the clamping platform 15 to move synchronously, realizing the precise clamping of the subsea pipeline by the clamping platform 15 and ensuring the stability during repair splicing.
