Description

Technical Field

[0001] The present invention relates to the technical field of submarine optical cable construction, and in particular to an adjustable junction box installation mechanism with a cable coiling function. Background Art

[0002] To enhance the digital capabilities of oil and gas platforms and enable communication and interconnection across offshore platforms, submarine optical cables are often used to connect the platforms to land and exchange information. The submarine cable is landed on the platform through a pre-installed steel protective conduit and then permanently secured to the top of the conduit using platform anchors. Once landed, the submarine cable is spliced ​​with the platform's optical cable to achieve grid connection. For safety reasons, the fiber splice section cannot be exposed to air and must be stored in a fiber optic junction box.

[0003] Considering the convenience of installation, the fiber optic junction box is generally placed near the platform anchor. However, the platform anchor is usually located at the bottom of the oil and gas platform, where the space is small and there is no pre-provided installation mechanism for the fiber optic junction box. Therefore, a separate installation mechanism is required.

[0004] In addition, after the submarine optical cable lands on the platform, a certain length needs to be reserved to prevent the submarine optical cable from being damaged and repaired in the future, and to be re-fused with the platform optical cable. If it is not reserved, the submarine optical cable will not be long enough to affect the optical fiber connection. The reserved submarine optical cable is scattered on the platform, which poses certain safety hazards and needs to be improved. Summary of the Invention

[0024] See also Figures 1 to 5 , embodiments of the present invention include:

[0025] like Figures 1 to 3The adjustable junction box installation mechanism with cable winding function shown is used for winding submarine optical cables 5 and installing junction boxes 3, and includes: a mounting bracket 2, an adjustable bracket 4 and a roller assembly 1. The roller assemblies 1 are distributed in a circular array on the front of the mounting bracket 2, forming an annular roller array for winding submarine optical cables 5. The roller assembly 1 is adjusted to change the diameter of the annular roller array to adapt to submarine optical cables 5 with different bending radii.

[0026] The junction box 3 is arranged on the front side of the bracket 2. In this embodiment, the junction box 3 is located inside the annular roller array, thereby improving space utilization.

[0027] The junction box 3 is provided with an ear seat 3-1, and the bracket 2 is provided with a junction box support 2-5 corresponding to the ear seat 3-1. Figure 1 As shown, the ears 3-1 are spaced apart on either side of the junction box 3, requiring four junction box supports 2-5. Adjustable brackets 4 are mounted on the junction box supports 2-5 to secure the ears 3-1. The adjustable brackets 4 cooperate with the junction box supports 2-5 to secure the ears 3-1, improving adaptability to junction boxes 3 of varying specifications.

[0028] like Figure 3 and Figure 4 As shown, a first waist hole 2-51 is vertically provided in the junction box support 2-5, and a first screw 2-52 for fixing the adjustable bracket 4 is provided in the first waist hole 2-51, so that the height of the adjustable bracket 4 can be adjusted and fixed to adapt to the position height of the ear seat 3-1.

[0029] In this embodiment, the adjustable bracket 4 adopts an L-shaped bent plate structure, and a second waist hole 4-1 is horizontally arranged on the adjustable bracket 4. A second screw 4-2 for fixing the ear seat 3-1 is arranged in the second waist hole 4-1. The second screw 4-2 can be adjusted horizontally in the second waist hole 4-1, which improves the adaptability to the horizontal position of the ear seat 3-1, has good versatility, and is easy to adjust.

[0030] like Figure 3 As shown, the mounting bracket 2 includes a column 2-1, a roller support 2-4, a crossbeam 2-6 and two base plates 2-2. The two base plates 2-2 are spaced apart laterally and can be fixed on the oil and gas platform by screws. The installation is convenient and the position is stable.

[0031] The columns 2-1 are vertically mounted on the base plate 2-2. The bottom of the columns 2-1 can be welded to the base plate 2-2, providing a strong structure. The back of the columns 2-1 is provided with reinforcing ribs 2-3 that extend diagonally downward to the base plate 2-2. The ends of the reinforcing ribs 2-3 are welded to each other. A connecting rod 2-7 is provided between the inner sides of the two columns 2-1. The ends of the connecting rod 2-7 are welded to each other, enhancing the overall structural strength.

[0032] Crossbeams 2-6 are spaced apart on the outside of the columns 2-1. In this embodiment, two vertically parallel crossbeams 2-6 are welded to the outside of each column 2-1. Roller supports 2-4 are distributed on the crossbeams 2-6 and the columns 2-1. Each crossbeam 2-6 has a horizontally positioned roller support 2-4 welded to it, while each column 2-1 has two vertically spaced roller supports 2-4 welded to it.

[0033] In this embodiment, a third waist hole 2-41 is provided in the roller support 2-4, and the roller assembly 1 is provided on the third waist hole 2-41. There are a total of eight roller supports 2-4, and eight roller assemblies 1 are installed accordingly. Through the design of the third waist hole 2-41, the eight roller assemblies 1 can be flexibly adjusted to form annular roller arrays with different radii.

[0034] The junction box supports 2-5 are spaced apart on the columns 2-1. Two junction box supports 2-5 are welded to each column 2-1, for a total of four junction box supports 2-5. The two roller supports 2-4 on the columns 2-1 are located above and below the junction box supports 2-5 and do not affect the installation of the junction box 3.

[0035] In this embodiment, the third waist hole 2-41 in the roller support 2-4 on the column 2-1 extends vertically, which is conducive to adjusting the height of the installation position of the corresponding roller assembly 1, and the third waist hole 2-41 in the roller support 2-4 on the beam 2-6 extends horizontally, which is conducive to adjusting the horizontal position of the corresponding roller assembly 1 to change the radius of the annular roller array, which is suitable for winding submarine optical cables 5 with different bending radii and storing a spare section of submarine optical cable 5.

[0036] like Figure 5 As shown, the roller assembly 1 includes a pin 1-1, a cable stop plate 1-2, and a roller 1-3. The pin 1-1 is inserted into the third waist hole 2-41. The pin 1-1 is provided with clamping nuts 1-4 located on both sides of the roller support 2-4. The pin 1-1 is provided with an external thread corresponding to the clamping nuts 1-4, facilitating assembly and adjustment. In this embodiment, a washer 1-5 is provided on the side of the clamping nuts 1-4 facing the roller support 2-4, providing high structural stability after assembly.

[0037] Roller 1-3 is mounted on pin 1-1 and positioned in front of roller support 2-4, allowing it to rotate and engage with submarine cable 5 to reduce friction. Roller 1-3 is made of PTFE insulation material, which has high chemical stability, low friction coefficient, good corrosion resistance and good insulation.

[0038] The optical cable limiting plate 1-2 is set on the pin shaft 1-1 and is located in front of the roller 1-3. The optical cable limiting plate 1-2 is used to limit the cable winding process of the submarine optical cable 5 to prevent the submarine optical cable 5 from falling off from the front of the roller 1-3 and improve stability.

[0039] In summary, the adjustable junction box installation mechanism with cable winding function pointed out in the present invention can adapt to the winding of submarine optical cables with different bending radii, and can also adapt to junction boxes of different specifications. There is no need to customize the design for junction boxes of different installation sizes or submarine optical cables with different bending radii, which greatly reduces costs. In addition, the structure is simple, and the installation and adjustment are convenient, which improves work efficiency.

[0040] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
