[0028] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0029] See also Figure 1-Figure 4 It should be noted that the illustrations provided in this embodiment are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components relevant to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be arbitrarily changed, and the component layout may also be more complex.

[0030] like Figure 1 As shown, this embodiment provides a ship cable pipe structure, which includes a pipe body, two sealing members 10 and two straight pipes 20. The pipe body is provided with two through holes arranged along the extension direction of the pipe body; the two sealing members 10 are arranged in the pipe body, and the two through holes are located between the two sealing members 10; the two straight pipes 20 are respectively connected to the two through holes, and the two straight pipes 20 are respectively used for injecting liquid sealing plugging and ventilation.

[0031] When using the above-mentioned marine cable conduit, the conduit body is installed through the bulkhead according to the drawings. The two straight tubes 20 can be fixed after the conduit body is installed, or one straight tube 20 can be fixed first, and the other straight tube 20 can be fixed after the conduit body is installed. The conduit body and the bulkhead are then welded and fixed. The cable is then laid through the conduit body, and the two sealing members 10 are installed within the conduit body. Finally, a liquid sealing material is poured into the cavity formed by the two sealing members 10 and the conduit body through one of the straight tubes 20. Once the liquid sealing material solidifies, it seamlessly seals the gaps between the cables, achieving both marine-grade watertightness and airtightness.

[0032] Previous plugging methods used modular plugging (solid type) and compression gaskets, which placed very high demands on the smooth arrangement of cables. In reality, once the cables were threaded through the tube, it was difficult to arrange them vertically and horizontally, resulting in poor sealing results. On-site construction workers found it difficult to seal the cables, and the cables were easily swept away during the sealing process. The marine cable conduit structure of this embodiment, on the other hand, requires less operator effort. There is no need to organize the cables threaded through the conduit. Once the cables are threaded, construction workers only need to inject liquid sealing material. This reduces operational difficulty and significantly improves cable sealing and installation efficiency. Furthermore, the cost of liquid sealing material is lower than that of modular materials, thus contributing to cost savings.

[0033] In order to facilitate laying of the cable in the pipe body, an opening 41 is opened on the pipe body. The opening 41 is arranged on the side of one of the blocking members 10 away from the through hole. The marine cable pipe structure also includes a cover member 30, which is detachably connected to the pipe body and covers the opening 41.

[0034] By providing the opening 41 on the pipe body, construction workers can lay the cable in the pipe body through the opening 41, thereby providing convenience for the construction workers.

[0035] The cover 30 is an arc-shaped plate with a handle on the top to facilitate lifting and lowering by construction workers. In order to enable the cover 30 to completely cover the opening 41, the size of the cover 30 along the extension direction of the tube body is larger than the size of the opening 41 along the extension direction of the tube body.

[0036] like Figure 1 and Figure 2 As shown, to facilitate installation by construction workers, the pipe body is a split design, comprising a first pipe section 40 and a second pipe section 50. An opening 41 is provided in the first pipe section 40, and two through-holes are provided in the second pipe section 50. Flanges 60 are provided on opposite sides of the first and second pipe sections 40, 50, respectively, and the two flanges 60 are connected by bolts. A flange 60 is also provided on the end of the first pipe section 40 away from the second pipe section 50. The other end of the first pipe section 40 is used to connect to the gas cable.

[0037] Specifically, when installing the pipe, construction workers first insert the second pipe section 50 through the bulkhead according to the drawings, then align the first and second pipe sections 40, 50, and finally connect the two flanges 60 with bolts. In this way, by designing the pipe as a split structure, the longer pipe is divided into two shorter first and second pipe sections 40, 50, making it easier for construction workers to carry and install.

[0038] like Figure 1-Figure 3As shown, a connecting piece 42 is provided on each side of the opening 41 , and the cover member 30 is provided with a connecting portion 31 corresponding to the two connecting pieces 42 . The connecting portion 31 and the connecting piece 42 are connected by bolts.

[0039] Specifically, the connecting members 42 are flat iron bars, and the two connecting members 42 can be welded and fixed to either side of the opening 41. The connecting portion 31 on the cover 30 is formed by bending the edge of the cover 30 outward. The two connecting portions 31 are symmetrically arranged about the central axis of the cover 30. When the cover 30 is placed on the opening 41, the two connecting portions 31 respectively abut the two connecting members 42. The connecting members 42 are detachably connected to the connecting portions 31 via bolts.

[0040] In order to prevent water from entering the gap between the cover 30 and the tube body during use, the marine cable tube structure further includes a seal 70, which is disposed between the cover 30 and the tube body and is used to seal the gap between the cover 30 and the tube body.

[0041] Specifically, the sealing member 70 is a rubber gasket, and a sealing member 70 is provided on the side of the connecting member 42 facing the connecting portion 31 and on the side where the first pipe section 40 contacts the cover member 30. When the cover member 30 is covered on the opening 41, the sealing member 70 seals the gap between the cover member 30 and the first pipe section 40.

[0042] In other embodiments, a clamping member is provided on each side of the opening 41 , and the cover member 30 is provided with clamping portions corresponding to the two clamping members, and the clamping members and the clamping portions are clamped and matched with each other.

[0043] Specifically, the clamping member may be a groove structure, and the clamping portion may be a protrusion structure. When the cover member 30 is placed on the opening 41, the clamping portion is inserted into the clamping member, and the clamping portion and the clamping member may be tightly fitted. Alternatively, the clamping portion may be a groove structure, and the clamping member may be a protrusion structure.

[0044] In this embodiment, the blocking member 10 is an expansion sealing plug. When the construction personnel install the two blocking members 10 in the second pipe section 50 , they spray water mist on the blocking members 10 . At this time, the blocking members 10 can form a seal in the second pipe section 50 .

[0045] In summary, the implementation process of the marine cable pipe structure of this embodiment is as follows: first, weld and fix one of the straight pipes 20 to a through hole of the second pipe section 50, then, according to the drawings, install the second pipe section 50 through the bulkhead, and make the bulkhead be located at half of the second pipe section 50. At this time, weld and fix the second pipe section 50 and the bulkhead, and finally, weld and fix the other straight pipe 20 to the other through hole. Align the first pipe section 40 with the second pipe section 50 and connect and fix the first pipe section 40 and the second pipe section 50 with bolts, then connect the other end of the first pipe section 40 to other cable pipes, and a continuous cable pipe is formed. When laying the cable, pull and release the cable into the pipe body through the opening 41 for construction. When the cable is laid, install two sealing members 10 in the second pipe section 50 and spray water mist to form a seal. Liquid sealing material is poured into the second pipe section 50 through the straight pipe 20, and finally the cover 30 is placed on the opening 41, and the cover 30 and the first pipe section 40 are connected and fixed with bolts. Therefore, the utility model effectively overcomes the various shortcomings of the existing technology and has high industrial application value.
