[0002] At present, during the construction of submarine cables for offshore wind farms, in order to guide the stable connection between the cables and other external equipment, a J-shaped pipe section is often set at the connection point to achieve protection. Since this J-shaped pipe section often guides the cable upward, and in order to prevent the cable from falling downward, a corresponding clamp is generally installed at the J-shaped pipe section to fix the position of the cable relative to the J-shaped pipe.

[0003] However, under the influence of external forces and some force majeure, the existing clamps are difficult to maintain the fixed position of the cable, causing the cable to slide downward from the original position, resulting in failure, and the maintenance construction cost is often high. The existing maintenance method is generally: recover the J-shaped tube section cable and cut it off, add a new cable, reinstall the center clamp and bend limiter, then re-insert the J-shaped tube, and finally connect. This maintenance method is expensive and takes a long time. Utility Model Content
