Description

Technical Field

[0001] This utility model generally relates to the field of marine technology, and specifically to a gooseneck cable penetration device for ships. Background Technology

[0002] To meet the requirements of cable routing across the deck and the ship's sealing performance, cable run-throughs are typically installed on the deck, through which cables pass. Existing cable run-throughs include gooseneck tubes and stuffing boxes adapted to be installed at the ends of the gooseneck tubes.

[0003] However, the existing cable penetrations described above have the following problems:

[0004] If you want to replace the gooseneck tube with a larger diameter one, you also need to replace the stuffing box that is compatible with it, which increases the difficulty and cost of the replacement. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a gooseneck cable penetration device for ships.

[0006] This application provides a gooseneck cable penetration device for ships, comprising:

[0007] Gooseneck tube, with a cable outlet end;

[0008] Stuffing gland, which is positioned opposite and spaced apart from the cable outlet end;

[0009] A reducing connector is located between the cable outlet and the stuffing box. The reducing connector includes a first connecting end and a second connecting end, which are fixedly connected to the cable outlet and the second connecting end is fixedly connected to the stuffing box. The diameter of the first connecting end is larger than the diameter of the second connecting end.

[0010] Furthermore, the reducing connecting pipe includes a frustum section and a cylindrical section arranged along the axial direction. The smaller diameter end of the frustum section is connected to the cylindrical section, the larger diameter end of the frustum section is connected to the cable outlet end, and the end of the cylindrical section away from the frustum section is connected to the stuffing box.

[0011] Furthermore, a protective tube is fixedly fitted around the outer periphery of the gooseneck tube, and the protective tube is used for welding to the deck.

[0012] Furthermore, the protective tube and the gooseneck tube are spot-welded together for fixation.

[0013] Furthermore, the first connecting end and the cable outlet are welded together, and the second connecting end and the stuffing box are welded together.

[0014] The gooseneck cable penetration device for ships provided in this application has a reducing diameter connecting pipe between the cable outlet end of the gooseneck tube and the stuffing box. The first connecting end of the reducing diameter connecting pipe is fixedly connected to the cable outlet end, and the second connecting end of the reducing diameter connecting pipe is fixedly connected to the stuffing box. The diameter of the first connecting end of the reducing diameter connecting pipe is larger than the diameter of the second connecting end of the reducing diameter connecting pipe. This not only allows the cable penetration device to be equipped with a larger diameter gooseneck tube, reducing the difficulty of cable threading in the gooseneck tube and alleviating the workload of cable threading personnel, but also allows the cable penetration device to replace the gooseneck tube with a larger diameter without replacing the stuffing box that is compatible with the current gooseneck tube, reducing the difficulty and cost of replacement. Attached Figure Description

[0015] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0016] Figure 1 This is a schematic diagram of the structure of the gooseneck cable penetration device provided in the embodiments of this application. Detailed Implementation

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] Please refer to the attached document. Figure 1 This application provides a gooseneck cable penetration device for ships, including a gooseneck tube 100, a stuffing box 200, and a reducing connecting pipe 300. The gooseneck tube 100 has an inlet end and an outlet end. The cable enters the gooseneck tube 100 from the inlet end and exits from the outlet end. The stuffing box 200 is positioned opposite and spaced apart from the outlet end, and the reducing connecting pipe 300 is located between the outlet end and the stuffing box 200. The reducing connecting pipe 300 includes a first connecting end and a second connecting end, the first connecting end being fixedly connected to the outlet end and the second connecting end being fixedly connected to the stuffing box 200, wherein the diameter of the first connecting end is larger than the diameter of the second connecting end.

[0019] In this embodiment, since the gooseneck tube 100 and the stuffing box 200 are connected by a reducing connecting pipe 300, and the first connecting end of the reducing connecting pipe 300 is fixedly connected to the cable outlet end and the second connecting end of the reducing connecting pipe 300 is fixedly connected to the stuffing box 200, the compatibility installation restriction between the gooseneck tube 100 and the stuffing box 200 is removed. This eliminates the need for compatibility installation between the gooseneck tube 100 and the stuffing box 200, thus eliminating the need to replace the stuffing box 200 with a larger diameter gooseneck tube 100 when replacing the cable penetration device, reducing the difficulty and cost of replacement. In addition, when the cable penetration device is equipped with a larger diameter gooseneck tube 100, the difficulty of threading the cable inside the gooseneck tube 100 is reduced, alleviating the workload of the cable threading personnel.

[0020] It should be understood that the first and second connecting ends of the reducing connecting pipe 300 can be adapted to the diameter of the current gooseneck pipe 100 and the size of the mounting part in the stuffing box 200, respectively.

[0021] The gooseneck tube 100 includes a straight tube section 110 and an arc tube section 120 connected to each other. The arc tube section 120 may be, but is not limited to, semi-circular. The cable inlet end is the end of the straight tube section 110 away from the arc tube section 120, and the cable outlet end is the end of the arc tube section 120 away from the straight tube section 110. Preferably, the gooseneck tube 100 can be formed by processing seamless steel pipe.

[0022] In some embodiments of this application, the reducing connector 300 includes a frustum section 310 and a cylindrical section 320 arranged axially. The smaller diameter end of the frustum section 310 is connected to the cylindrical section 320, and the larger diameter end of the frustum section 310 is connected to the cable outlet end. The end of the cylindrical section 320 away from the frustum section 310 is connected to the stuffing box 200. This arrangement facilitates connection of the cylindrical section 320 to the stuffing box 200, and the inner wall of the frustum section 310 guides the cable to pass more smoothly through the reducing connector 300.

[0023] The large-diameter end of the frustum section 310 forms the first connecting end of the reducing connecting pipe 300, and the end of the cylindrical section 320 away from the frustum section 310 forms the second connecting end of the reducing connecting pipe 300.

[0024] In some embodiments of this application, the first connecting end and the cable outlet end are welded together, the stuffing box 200 is a welded stuffing box 200, and the second connecting end and the stuffing box 200 are welded together. Of course, in other embodiments, the stuffing box 200 can also be a screw-on stuffing box 200, which is screwed to the second connecting end.

[0025] In some embodiments of this application, a protective tube 400 is fixedly sleeved on the outer periphery of the gooseneck tube 100. The protective tube 400 is used for welding with the deck 500 to avoid damage to the gooseneck tube 100 caused by direct welding between the gooseneck tube 100 and the deck 500.

[0026] The protective pipe 400 and the gooseneck pipe 100 can be fixedly connected by, but is not limited to, spot welding or bonding. Optionally, the protective pipe 400 is sleeved on the straight pipe section 110 of the gooseneck pipe 100.

[0027] This application also provides a vessel, including a deck 500 and the aforementioned gooseneck cable penetration device.

[0028] The deck 500 is provided with mounting holes, the gooseneck tube 100 passes through the mounting holes and the protective tube 400 is located at the mounting holes, and the protective tube 400 and the deck 500 are welded together.
