Description

Technical Field

[0001] The present invention relates to the technical field of ships and marine engineering equipment, and in particular to a cable cabin penetration and docking device. Background Art

[0002] Marine cables are used to connect various electrical equipment in the ship's power grid to transmit electrical energy or electrical signals. With the continuous improvement of ship electrification and automation, the variety and usage of marine cables are increasing. Marine cables are basically divided into three categories: power cables, communication cables and special high-frequency cables. Among them, power cables are used for power and lighting systems and are the most used cables on board. For power cables, current carrying capacity is an important technical indicator. The current carrying capacity generally depends on the temperature resistance grade of the cable insulation material.

[0003] Generally, ships and offshore structures use external cables, that is, they are dropped into the water from a waterless area. This method wastes cables and cannot be repaired after being damaged. The cables can only be replaced in their entirety, causing great economic losses. The use of traditional sealant underwater sealing methods has the potential to cause seal damage over time and seawater backflows into the cabin from the side holes, causing safety hazards to the ship. In addition, it is difficult to inspect and quickly replace the ships during navigation or mooring, and this problem can only be solved when the ship is docked for repair, which greatly increases maintenance costs and reduces maintenance cycles.

[0041] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0042] Figure 1 Schematic diagram of the overall structure of the cable penetration device in an embodiment of the present invention; Figure 2 is a side view of a cable penetration device in an embodiment of the present invention; Figure 3 This is a schematic structural diagram of a clamping device for a cable cabin penetration device in an embodiment of the present invention; Figure 4 A bottom view of a fastener of a cable penetration device in an embodiment of the present invention; Figure 5 Schematic diagram of the fastener structure of the cable penetration device in an embodiment of the present invention; Figure 6 It is a schematic diagram of the structure of the pressure-resistant fixing member of the cable cabin penetration device in an embodiment of the present invention.

[0043] like Figure 1As shown, the cable penetration device in the present invention is used to be installed on the installation through hole 61 of the plate-shaped member 6, wherein the cable penetration device comprises: a pressure-resistant fixing member 1, a plurality of conductors 2, a fastener 3, a cable fastener 4 and a sealing ring 5. The material of the pressure-resistant fixing member 1 can be made of ceramic, and the pressure-resistant fixing member 1 comprises: an upper fixing portion 11, an interaxial portion 12 and a lower fixing portion 13. The upper fixing portion 11 is penetrated in the installation through hole 61 of the plate-shaped member 6, and the upper fixing portion 11 can be fixed in the installation through hole 61 by threaded connection. The interaxial portion 12 is located below the plate-shaped member 6, and the interaxial portion 12 is supported on the plate-shaped member 6, and the lower fixing portion 13 is located below the interaxial portion 12. The plurality of conductors 2 can be three, and the three conductors 2 can increase its conductive performance, and multiple built-in conductors of different specifications and types can be configured according to actual needs for different usage situations. The three conductors 2 run through the entire pressure-resistant fixing member 1, and respectively pass through the surface of the upper fixing portion 11 and the surface of the lower fixing portion 13. There is a cable fastener 4 below the lower fixing part 13, and a cable docking port 41 is provided on the cable fastener 4. The lower fixing part 13 is sleeved in the cable docking port 41, so that the underwater cable is connected to the pressure-resistant fixing part 1 through the cable fastener 4. One end of the pressure-resistant fixing part 1 is connected to the cable in the cabin, and the other end is connected to the underwater cable by inserting into the cable docking port 41. The three conductors 2 are electrically connected to the underwater cable through the cable docking port 41. A fastener 3 is also provided above the plate-shaped part 6. The fastener 3 is used to tightly fix the pressure-resistant fixing part 1 to the plate-shaped part 6. A first through hole 31 is provided on the fastener 3, and the pressure-resistant fixing part 1 passes through the first through hole 31 to fix the fastener 3 on the plate-shaped part 6. The lower surface of the fastener 3 is a plane, and is tightly fitted with the upper surface of the plate-shaped part 6, which increases the contact area with the plate-shaped part 6 and prevents the pressure-resistant fixing part 1 from falling off the plate-shaped part 6. Through the action of the fastener 3, the plate-shaped part 6 is firmly fixed on the pressure-resistant fixing part 1. A sealing ring 5 is provided below the fastener 3, and the sealing ring 5 is located between the fastener 3 and the plate-shaped member 6. A sealing ring 5 is provided on the surface of the inter-axial portion 12, and the sealing ring 5 is located between the inter-axial portion 12 and the plate-shaped member 6. Since this device is connected to an underwater cable for use in water, the presence of the sealing ring 5 ensures the watertightness of the device and prevents water from entering between the pressure-resistant fixing member 1 and the plate-shaped member 6, thereby solving the problem of underwater cable penetration and docking and extending the service life of the device.

[0044] It is not difficult to find from the above content that the cable cabin docking device of the present invention is used to be installed on the installation through hole 61 of the plate-shaped member 6, and includes: a pressure-resistant fixing member 1, a plurality of conductors 2, a fastener 3, a cable fastener 4 and a sealing ring 5. The pressure-resistant fixing member 1 includes: an upper fixing portion 11, an interaxial portion 12 and a lower fixing portion 13. The upper fixing portion 11 passes through the installation through hole 61, and the interaxial portion 12 abuts against the lower side of the plate-shaped member 6. The lower surface of the fastener 3 is a plane and abuts against the surface of the plate-shaped member 6. The fastener 3 is provided with a first through hole 31, and the upper fixing portion 11 is fixed to the upper fixing portion 11 through the first through hole 31. The cable fastener 4 is located below the pressure-resistant fixing member 1 and is detachably connected to the pressure-resistant fastener 3. The plurality of conductors 2 are located inside the pressure-resistant fastener 3 and can extend into the cable docking port 41 located on the cable fastener 4. The sealing ring 5 on the fastener 3 is located between the fastener 3 and the plate-shaped member 6, and the sealing ring 5 on the shaft portion 12 is located between the shaft portion 12 and the plate-shaped member 6. The cable cabin docking device of the embodiment of the present invention is provided by fixing the pressure-resistant fastener 3 on the plate-shaped member 6, and a plurality of conductors 2 are inserted into the interior of the pressure-resistant fixture 1. One end of the pressure-resistant fixture 1 is connected to the cable in the cabin, and the other end is connected to the underwater cable by inserting into the cable docking port 41. The fastener 3 is used to tightly connect and fix the pressure-resistant fixture 1 and the plate-shaped member 6 together. The sealing ring 5 located on the fastener 3 and the shaft portion 12 can strengthen the sealing effect between the fastener 3 and the plate-shaped member 6, and between the plate-shaped member 6 and the shaft portion 12, thereby ensuring the watertightness of the cable cabin docking device. The cable cabin docking device has a simple structure and is easy to operate, which solves the problem of underwater cable cabin docking. In addition, the cable replacement does not require the replacement of the cabin docking parts, which can achieve quick disassembly and assembly, reduce maintenance costs and operating costs, and ensure the ship's operating cycle.

[0045] like Figure 6 As shown, optionally, in this embodiment, a first external thread 111 is provided on the surface of the upper fixing portion 11, a first through hole 31 is provided on the fastener 3, and a first internal thread 311 is provided on the inner wall of the first through hole 31. The first internal thread 311 on the fastener 3 is connected with the first external thread 111 on the upper fixing portion 11 through a thread, and the fastener 3 is continuously tightened toward the plate-shaped member 6 through the thread until it abuts against the upper surface of the plate-shaped member 6. Since the lower surface of the fastener 3 is a plane, the fastener 3 can be completely attached to the surface of the plate-shaped member 6, increasing the contact area between the plate-shaped member 6 and the fastener 3, so that the pressure-resistant fixing member 1 is better fixed on the plate-shaped member 6. A second external thread 131 is provided on the surface of the lower fixing portion 13, and a second internal thread 42 is provided inside the cable fastener 4. The cable fastener 4 is provided with a cable docking port 41, and the cable fastener 4 is sleeved on the lower fixing portion 13 through the cable docking port 41. Since the lower fixing portion 13 has a second external thread 131 and the cable fastener 4 has a second internal thread 42, the cable fastener 4 is continuously tightened on the lower fixing portion 13 through the thread, so that the three conductors are electrically connected with the underwater cable.

[0046] like Figure 5 As shown, optionally, in this embodiment, the fastener 3 is a regular polygon. The polygonal fastener 3 can help tighten, and it is more convenient to tighten the fastener 3 on the plate-shaped member 6 manually.

[0047] Optionally, in this embodiment, the cable cabin penetration device further includes: a clamping device 7. There are two clamping devices 7, which are respectively located above the plate-shaped member 6 and are arranged at the left and right ends of the fastener 3 to hold the fastener 3. When the fastener 3 fixes the pressure-resistant fixing member 1 and the plate-shaped member 6, the fastener 3 may become loose due to long-term work. If the fastener 3 becomes loose, it will affect the use of the underwater cable and its service life. With the clamping device 7 held at the left and right ends of the clamping member, the fastener 3 can be prevented from loosening, so that the fastener 3 is always in a prohibited state, and the pressure-resistant fixing member 1 and the plate-shaped member 6 are maintained fixed.

[0048] like Figure 3 As shown, optionally, in this embodiment, the clamping device 7 includes: a clamping plate 71, a pull rod 72, a first fixed column 73 and a fixed plate 74. The fixed plate 74 is divided into a fixed portion and a vertical portion. The fixed portion is fixed on the plate-shaped member 6, and a through hole is provided on the vertical portion. The pull rod 72 is provided on the vertical portion so that the pull rod 72 can move freely on the vertical portion. The moving direction and position direction of the pull rod 72 are parallel to the fixed portion. A plurality of second through holes 742 are provided on the pull rod 72, and the plurality of second through holes 742 are evenly distributed on the pull rod 72. A fixing hole 741 is provided on the upper surface of the vertical portion, and the fixed column 73 is provided in the fixing hole 741 and the plurality of second through holes 742. A clamping plate 71 is provided at the end of the pull rod 72, and the clamping plate 71 abuts against the fastener 3. Since the fastener 3 is a regular polygon, the clamping plate 71 can fit closely with the side wall of the fastener 3, thereby increasing the contact area between the clamping plate 71 and the fastener 3 and making the force-bearing area larger. When the clamping plate 71 is in contact with the fastener 3, the position of one of the second through holes 742 coincides with the position of the fixing hole 741, and the fixing column 73 is inserted between the fixing hole 741 and the second through hole 742, so that the pull rod 72 is fixed on the fixing plate 74, and the clamping plate 71 is in contact with the fastener 3. When the fastener 3 needs to be loosened and the pressure-resistant fixing member 1 is removed from the plate-shaped member 6, the fixing column 73 can be pulled out of the fixing hole 741, and the pull rod 72 can be pulled outward, so that the pull rod 72 drives the clamping plate 71 to move outward, so that the clamping plate 71 is separated from the fastener 3. When the pull rod 72 is pulled to a certain distance, the other second through holes 742 coincide with the fixing holes 741, and the fixing columns 73 are inserted into the second through holes 742 and the fixing holes 741, so that the pull rod 72 is fixed on the fixing plate 74. At the same time, the position of the clamping plate 71 is also fixed, and the clamping plate 71 has a certain distance relative to the fastener 3, so that the fastener 3 can be removed from the pressure-resistant fixing member 1.

[0049] Optionally, in this embodiment, a first baffle 711 and a second baffle 712 are provided on the pressing plate 71. The second baffle 712 is located below the first baffle 711, and the pull rod 72 is located between the first baffle 711 and the second baffle 712. The first baffle 711, the pull rod 72 and the second baffle 712 are fixed by bolts, so that the pull rod 72 is fixed on the pressing plate 71. The pressing plate 71 and the pull rod 72 are detachably connected. When the pressing plate 71 or the pull rod 72 is damaged, the bolts can be removed to separate the pull rod 72 from the pressing plate 71, so as to facilitate replacement and maintenance.

[0050] Optionally, in this embodiment, the clamping device 7 further includes: two springs. The two springs are respectively located between the clamping plate 71 and the fixing plate 74, and the two springs are symmetrical about the pull rod 72. One end of the spring is fixed to the clamping plate 71, and the other end is fixed to the fixing plate 74. When the clamping plate 71 is pressed against the side wall of the fastener 3, the spring is in a compressed state, and the spring in the compressed state has a holding force on the clamping plate 71, so that the clamping plate 71 and the fastener 3 fit more closely. The springs are arranged on the left and right sides to increase the acting force of the springs.

[0051] In the present invention, unless otherwise clearly specified and limited, a first feature being “on” or “under” a second feature may mean that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact via an intermediate medium.

[0052] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0053] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
