Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] As shown in the figure, a pressure-resistant cable conduit for penetrating a liquid tank includes an end cable conduit 10, an end cable conduit connecting flange 11, an end cable conduit fixing flange 12, a seat plate 13, an internal cable conduit 20, and an internal cable conduit connecting flange 21.

[0022] The internal cable conduit 20 is pre-embedded inside the liquid tank, and the internal cable conduit connecting flange 21 is installed at the end of the internal cable conduit 20 for connecting the internal cable conduit 20 to the end cable conduit 10.

[0023] A reserved hole 2 is provided on the liquid tank wall 1. A seat plate 13 is installed at the reserved hole 2 on the inner surface of the liquid tank. The end cable pipe 10 extends into the liquid tank through the reserved hole 2. An end cable pipe connecting flange 11 and an end cable pipe fixing flange 12 are installed sequentially at the extension end of the end cable pipe 10. The end cable pipe fixing flange 12 is connected to the seat plate 13 and is fixed by bolts, fixing the end cable pipe 10 to the liquid tank wall 1 in a cantilever manner, without the need for pipe supports to lay cables. The end cable pipe connecting flange 11 is located at the end of the end cable pipe 10. The end cable pipe connecting flange 11 is connected and fixed to the inner cable pipe connecting flange 21 by bolt assembly, connecting the end cable pipe 10 and the inner cable pipe 20 together, meeting the requirements for cable laying.

[0024] To ensure the stability of the structure in this embodiment, the base plate 13 is disc-shaped, and different specifications are selected according to the opening size of different reserved holes 2. One end face is welded to the inner surface of the liquid tank, and the other end face is connected to the end cable pipe 10 through the end cable pipe fixing flange 12.

[0025] To optimize the structure of this embodiment, the seat plate 13 is welded to the reserved hole 2 on one side of the liquid tank wall 1.

[0026] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0027] Since an internal cable pipe connecting flange 21 is installed at the end of the internal cable pipe 20, the internal cable pipe 20 can be connected to the end cable pipe 10, which facilitates the laying of cables inside the liquid tank.

[0028] Since a mounting plate 13 is installed at the reserved hole 2 in the liquid tank wall 1, one end of the end cable pipe 10 extending into the liquid tank is connected to the mounting plate 13 through the end cable pipe fixing flange 12, and the other end is connected to the internal cable pipe connecting flange 21 on the internal cable pipe 20 through the end cable pipe connecting flange 11. Therefore, the internal cable pipe 20 is connected to the end cable pipe connecting flange 11 through the internal cable pipe connecting flange 21, thereby connecting the internal cable pipe 20 and the end cable pipe 10. There is no need to install pipe supports, thus avoiding the cutting and grinding work of cable binding supports caused by the adjustment of the cable laying path, and meeting the requirements of cable laying.

[0029] The working principle of this embodiment:

[0030] This embodiment mainly consists of a base plate 13, an end cable conduit 10, an internal cable conduit 20, an end cable conduit connecting flange 11, an end cable conduit fixing flange 12, and an internal cable conduit connecting flange 21. This embodiment facilitates installation, adjustment, and disassembly. The end cable conduit 10 and internal cable conduit 20 can be flexibly selected to match the overall cross-sectional area of ​​the cable bundle, eliminating the need for overhead pipe installations. This avoids the risk of modifications due to interference between cable binding supports and structures or equipment caused by limited space. It also avoids the need for cutting, grinding, and repainting of outfitting components and the interior of the liquid tank during hot work on the surface structure. It offers good stability, simple operation, and ease of construction. It is suitable for use as a cable laying channel on ships.

[0031] The working process of this embodiment:

[0032] Step 1: Select the end cable conduit 10 and the internal cable conduit 20. Choose the cable conduit specifications and models according to the outer diameter of the cable to be installed. Generally, ensure that the overall cross-sectional area of ​​the cable bundle does not exceed 40% of the usable cross-sectional area of ​​the cable conduit.

[0033] Step 2: Select the end cable pipe connecting flange 11, end cable pipe fixing flange 12, internal cable pipe connecting flange 21 and seat plate 13. The inner diameter of the end cable pipe connecting flange 11, end cable pipe fixing flange 12 and internal cable pipe connecting flange 21 matches the outer diameter of the end cable pipe 10 and internal cable pipe 20. The screw holes of the seat plate 13 match the screw holes of the end cable pipe connecting flange 11, end cable pipe fixing flange 12 and internal cable pipe connecting flange 21.

[0034] Step 3: Bolt assembly selection. Since the environment where the cable conduit is located is not a high-temperature environment, the surface of the bolt assembly should be treated with zinc-aluminum composite coating.

[0035] Step 4: Installation of end cable pipe 10 and internal cable pipe 20. Before welding the internal liquid tank structure, complete the positioning and installation of internal cable pipe 20. All supporting legs of a section of internal cable pipe 20 should be evenly stressed.

[0036] Step 5: Connect the end cable pipe connecting flange 11, the end cable pipe fixing flange 12, and the internal cable pipe connecting flange 21. When connecting the flanges to each other or to the seat plate 13, ensure that the mating surfaces are well aligned in a free state. The gap should be equivalent to the thickness of the flange gasket, that is, the flange gasket can be inserted into the mating surface without obstruction when there is no external force.

[0037] Step 6: When tightening the connecting bolt assembly, use a standard wrench to tighten it multiple times in an even and staggered manner, and secure it in place;

[0038] Step 7: Conduct hydraulic tests as required, including strength tests and tightness tests.

[0039] Features of this embodiment:

[0040] The cable conduit is easy to install, securely installed, and has good sealing performance with the liquid tank structure. The connecting plate 13 can be selected according to the actual outer diameter of the cable conduit, avoiding the problem that the cable binding bracket on the surface of the liquid tank cannot be modified or the internal space of the ship is insufficient to meet the cable laying requirements. It maximizes the use of the internal space of the ship and avoids the cutting and grinding work of the cable binding bracket caused by the adjustment of the cable laying path. It has the characteristics of strong adaptability, good stability and easy construction.

[0041] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of the end cable pipe 10, the internal cable pipe 20, the end cable pipe connecting flange 11, the end cable pipe fixing flange 12 and the internal cable pipe connecting flange 21 are not specifically limited and can be determined using conventional equipment. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
