Abstract
Description
Technical Field
[0001] This utility model relates to a dynamic submarine cable installation bracket, belonging to the field of cable construction technology. Background Technology
[0002] After the floating offshore wind power dynamic submarine cable (also known as a submarine cable) passes through the hollow shaft of the buoy at the bottom of the turret, the cable needs to be stripped of its armor at the anchorage point. Approximately 20 meters of cable should be reserved between the anchorage and the turret's high-voltage switchgear. To facilitate dynamic adjustment of this reserved cable length, the reserved cable section should be coiled in an arc.
[0003] Existing technologies for circularly coiled cables exist. See Chinese Patent Publication No. CN113700621A. Although using a cycloidal saddle can coil the cable in a circular arc, the cycloidal saddle used for longer cables is relatively large, resulting in an increase in the weight of the integral cycloidal saddle. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a dynamic submarine cable installation bracket.
[0005] This utility model is achieved through the following technical solution.
[0006] This utility model provides a dynamic submarine cable installation bracket, comprising:
[0007] It is placed horizontally in the middle of the long horizontal bar;
[0008] Vertical bar, short horizontal bar.
[0009] Three spaced vertical bars are fixed on the long horizontal bar; the horizontal ends of the long horizontal bar protrude outwards from the vertical bars; the upper and lower ends of the vertical bars are connected by short horizontal bars.
[0010] The vertical bar on the outer side is fixedly connected to both ends of the long horizontal bar by a diagonal bar, and the diagonal bar is in an inclined state.
[0011] The vertical rod in the middle is fixed with a hollow shaft.
[0012] Cable clamps for holding the submarine cable are fixedly connected at the intersection of the short horizontal bar and the vertical bar, as well as at both ends of the long horizontal bar.
[0013] The submarine cable runs through the cable clamp holding coil in an arc, with a straight distribution path from the lower left, upper left, upper right, lower right, and left side.
[0014] The beneficial effects of this utility model are as follows: Since the dynamic submarine cable installation bracket is a frame structure composed of long horizontal bars, vertical bars and short horizontal bars, it is lighter than the integral cycloidal saddle, and is easier to operate and install on the hollow shaft, thus solving the problem of increased overall weight caused by the larger size of the cycloidal saddle used for longer cables.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.
[0021] like Figures 1 to 3 As shown.
[0022] This application discloses a dynamic submarine cable installation bracket, comprising:
[0023] A long horizontal bar 1 is positioned horizontally in the middle, and three vertical bars 2 are fixed on the long horizontal bar 1 at intervals; the two ends of the long horizontal bar 1 protrude outward from the vertical bars 2; the upper and lower ends of the vertical bars 2 are connected by short horizontal bars 3.
[0024] The vertical rod 2 on the outside is fixedly connected to both ends of the long horizontal rod 1 by the diagonal rod 5, and the diagonal rod 5 is in an inclined state.
[0025] The vertical rod 2, located in the middle, is used to fix it to the hollow shaft 7.
[0026] Cable clamps 4, which hold the submarine cable 6, are fixedly connected at the intersection of the short horizontal bar 3 and the vertical bar 2, and at both ends of the long horizontal bar 1. The 20-meter-long submarine cable 6 runs through the cable clamp 4 in an arc shape, with a distribution path that runs straight up from the lower left, upper left, upper right, lower right, and left side, and then connects to the turret high-voltage cabinet.
[0027] Because the dynamic submarine cable installation bracket is a frame structure consisting of a long horizontal bar 1, a vertical bar 2, and a short horizontal bar 3, it is lighter than an integral cycloidal saddle and is easier to operate and install onto the hollow shaft 7, thus solving the problem of increased overall weight caused by the larger size of the cycloidal saddle used for longer cables.
[0028] When clamping and limiting the middle of a cable, the existing cable clamping and limiting technology, as seen in Chinese Patent Publication CN218472714U, can clamp and limit the cable through two sets of clamps. However, when there are cable bundles of different diameters coiled together, the two sets of clamps cannot independently clamp and limit the cable bundles of different diameters.
[0029] A cable clamp 4 according to this application includes:
[0030] The lower half-clamp 41 is welded and fixedly connected to the dynamic submarine cable installation bracket. The middle half-clamp 42 and the upper half-clamp 45 are respectively installed on the outer side of the lower half-clamp 41.
[0031] There is a large cable hole 43 between the lower half clamp 41 and the middle clamp 42, which allows the large diameter cable of the submarine cable to pass through. A large diameter elastic buffer layer 44 is fixed to the inner diameter surface of the large cable hole 43.
[0032] Between the intermediate clamp 42 and the upper clamp 45, there is a medium cable hole 46 and a small cable hole 48, which allow the medium-diameter and small-diameter wires of the submarine cable 6 to pass through; the inner diameter surfaces of the medium cable hole 46 and the small cable hole 48 are respectively fixed with a medium-diameter elastic buffer layer 47 and a small-diameter elastic buffer layer 49.
[0033] The submarine cable, with its six large, medium, and small diameter wires, is independently clamped and limited by passing through the large cable hole 43, medium cable hole 46, and small cable hole 48, thus solving the problem that two sets of clamping plates cannot independently clamp and limit cable bundles of different diameters.
[0034] The lower half clamp 41, the middle clamp 42, and the upper half clamp 45 are detachably fixed together by two spaced screws 50.
