Description

Technical Field

[0002] With the continuous growth of global communication demand and the deepening of offshore energy development, the scale of the submarine cable market has been continuously expanding. More than 95% of the transoceanic data in the world is transmitted by submarine cables. As one of the components of the submarine optical cable system, the performance of the submarine cable cluster fixing device is directly related to the efficiency and stability of information transmission.

[0003] Traditional submarine cables can rely on J-type pipes to land on oil and gas platforms, but the premise is that the oil and gas platforms have reserved J-type pipe resources in advance. Some oil and gas platforms did not reserve J-type pipes in advance or the J-type pipes have been fully utilized, and there are often no spare J-type pipes for submarine cables to land on oil and gas platforms.

[0004] In the design of submarine cables, multiple small-sized cluster submarine cables may be suspended at the cable landing point on an oil and gas platform. Multiple cluster submarine cables are prone to collision interference during operation, affecting the stability and safety of the submarine cables. In addition, due to the same intercept during cable integration, one group of cores is prone to instantaneous charge accumulation on other group circuits at different transmission frequencies and voltages, causing electromagnetic interference, and improvement is needed. Content of the Utility Model

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1 to 4 , the embodiments of the present utility model include:

[0024] As Figures 1 to 4 shown, the multi-cable cluster fixing device with parallel arrangement includes: a bending strengthening assembly 2, a submarine cable clamping assembly 4, a fixing base 1, and a cover plate 5. The cover plate 5 is detachably arranged on the front of the fixing base 1. In this embodiment, one side of the cover plate 5 and one side of the fixing base 1 are movably connected by a hinge 3, which is convenient for flipping open or closing. The other side of the cover plate 5 and the other side of the fixing base 1 are fixedly connected by arranging a second bolt-nut assembly. The fixing base 1 and the cover plate 5 are made of steel structure, and the assembled structure is stable.

[0025] As Figure 2As shown, on the front of the fixed seat 1 and the back of the cover plate 5, there are embedding grooves 11 corresponding one-to-one to the submarine cable clamping assemblies 4. The embedding grooves 11 extend vertically and are distributed at intervals parallel to each other left and right on the front of the fixed seat 1 and the back of the cover plate 5. The number of the submarine cable clamping assemblies 4 is at least 2. In this embodiment, 5 submarine cable clamping assemblies 4 are used to fix 5 submarine cables. Therefore, the number of the embedding grooves 11 is 5.

[0026] The fixed seat 1 can be installed on the support frame of the oil and gas platform. After clamping multiple submarine cables respectively through the submarine cable clamping assemblies 4, the cover plate 5 is used to fix the submarine cable clamping assemblies 4 on the fixed seat 1, realizing the left-right spaced and parallel fixation of multiple submarine cables, and controlling the distance between adjacent 2 submarine cables through the submarine cable clamping assemblies 4, avoiding the problems of mutual intersection and electromagnetic interference of the submarine cables.

[0027] As Figure 3 shown, the submarine cable clamping assembly 4 includes a symmetrically arranged first clamping block 41 and a second clamping block 42. On the front of the first clamping block 41 and the second clamping block 42, there are respectively concave optical cable clamping grooves 45 extending along their axial directions, which can clamp and fix the submarine cables. In this embodiment, on both sides of the back of the first clamping block 41 and the second clamping block 42, there are respectively relatively arranged grooves 44. In the opposite two grooves 44, a first bolt and nut assembly is arranged to connect the first clamping block 41 and the second clamping block 42, realizing the clamping of the submarine cables. The first clamping block 41 and the second clamping block 42 are made of steel structure, and the structure is stable.

[0028] In this embodiment, the cross-sections of the embedding grooves 11 and the optical cable clamping grooves 45 are semi-circular structures, and the cross-sections of the first clamping block 41 and the second clamping block 42 are respectively semi-circular structures, so that the first clamping block 41 and the second clamping block 42 can be placed into the embedding grooves 11 and are fixed by the closing of the fixed seat 1 and the cover plate 5.

[0029] To improve the axial stability of the first clamping block 41 and the second clamping block 42, arc-shaped positioning grooves 43 are respectively arranged on the backs of the first clamping block 41 and the second clamping block 42, and positioning ribs 12 corresponding to the arc-shaped positioning grooves 43 are arranged in the embedding grooves 11 to perform axial positioning of the first clamping block 41 and the second clamping block 42 in the embedding grooves 11, avoiding the problem of axial sliding. As Figure 2 shown, the positioning ribs 12 are located in the middle of the axial direction of the embedding grooves 11, and the embedding grooves 11 and the positioning ribs 12 are concentric, which is convenient for processing and assembly.

[0030] As Figure 4As shown in the figure, the bending reinforcement assembly 2 includes bending reinforcement sleeves 21 located at both ends of the submarine cable clamping assembly 4. A flange 22 is provided at one end of the bending reinforcement sleeve 21 close to the submarine cable clamping assembly. Screws for connecting to the corresponding end of the submarine cable clamping assembly 4 are provided on the flange 22, and the structure is firm. Through holes 24 corresponding to the screws are provided on the flange 22, and threaded holes 46 corresponding to the through holes 24 are provided at both ends of the first clamping block 41 and the second clamping block 42 respectively, which is convenient for assembly. In this embodiment, the radius of the flange 22 is greater than the radius of the embedding groove 11 to prevent the flange 22 from entering the embedding groove 11 for axial limitation of the flange 22.

[0031] To improve the structural stability, the bending reinforcement assembly 2 further includes a rib plate 23 located between two adjacent bending reinforcement sleeves 21 to enhance the bending resistance effect of the bending reinforcement assembly 2. In this embodiment, the bending reinforcement sleeve 21, the rib plate 23 and the flange 22 adopt an integrated insulating plastic structure for electrical isolation between adjacent submarine cables and improve the use safety.

[0032] In summary, a multi-cable cluster fixing device with parallel arrangement pointed out by the present utility model has a compact structure, occupies a small installation space, can fix multiple submarine cables at parallel intervals, is convenient for construction, and improves the structural stability and anti-interference effect.
