Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine technology, and in particular to a split-type cable penetration component. Background Technology
[0002] In cable laying projects, cable penetrations play a crucial role, ensuring the sealing and safety of cables when passing through obstacles such as ship hulls and walls. Currently, there are two main methods for installing cable penetrations: grouting and sealing with plugs. However, both methods have strict requirements regarding the timing of the penetration frame installation; it must be completed before the cable is inserted. Once the cable has been inserted, it is difficult to install the cable frame.
[0003] In actual engineering projects, it is common for equipment or cable penetration components to arrive late or not at all. In such cases, if an integral cable penetration component is used, it cannot be installed after the cable is pulled or connected, which will cause great inconvenience to on-site construction, potentially leading to project delays and increased construction costs. Utility Model Content
[0004] The purpose of this utility model is to provide a split-type cable penetration component to solve the problem that existing integral cable penetration components cannot be installed after cable pulling or wiring when equipment or drive bay components are delayed in arrival, thereby improving the flexibility and construction efficiency of cable installation.
[0005] To achieve the above objectives, this utility model provides a split-type cable penetration component, including a cable threading frame inserted into the hull structure. The cable threading frame includes an annular channel formed by a side plate and a flange plate fixed to one end of the outer side of the annular channel. The annular channel is filled with sealant. The cable enters from one end of the annular channel and exits from the other end. Two dividing lines are provided on the side wall of the annular channel along the extension direction of the annular channel, dividing the cable threading frame into two interlocking frame units. Each frame unit is fixed to the hull structure.
[0006] With the above structure, this split design allows the two frame units to be snapped together from both sides of the cable after it has been pulled or connected, forming a cable threading frame, which is then inserted into the hull structure. Each frame unit is fixed to the hull structure, thus solving the problem of inconvenient installation of integral cable threading components and improving the flexibility of cable installation.
[0007] Preferably, flange holes are evenly distributed on the flange plate, and threaded holes are provided on the hull structure corresponding to the flange holes. This structure allows for installation in special scenarios, such as when the hull wall is thin and welding is not possible.
[0008] Preferably, the outer side of the flange plate has the same geometry as the outer wall of the cable conduit frame, and its circumferential dimension is larger than the corresponding dimension of the cable conduit frame, forming a radially expanding flange structure. This design can increase the contact area between the flange plate and the hull structure, improving the sealing effect and fixing stability.
[0009] By filling the annular channel with sealant and ensuring a tight fit between the flange plate and the hull structure, the sealing of the cable penetration can be guaranteed, preventing water, dust, and other contaminants from entering the hull structure and ensuring the safe operation of equipment and cables.
[0010] Preferably, the cross-section of the annular channel is rectangular.
[0011] Preferably, the cross-section of the annular channel is elliptical.
[0012] Preferably, the two dividing lines are symmetrically arranged on both sides of the annular channel. This makes the two frame units structurally symmetrical, easy to install, and ensures uniform stress distribution.
[0013] Preferably, the two frame units are provided with a limiting structure to restrict their docking position; the limiting structure includes an insert block disposed on one frame unit and a slot disposed on the other frame unit for the insert block to be inserted into. Through the cooperation of the insert block and the slot, the accurate positioning of the two frame units during docking can be ensured, thus guaranteeing the stability of the annular channel.
[0014] Preferably, there are two limiting structures, located at the positions of the two dividing lines respectively. This further improves the accuracy and stability of the docking of the two frame units.
[0015] Preferably, the insert includes a stop plate located at the dividing line on one of the frame units and bent into the annular channel, and a limiting block located on the stop plate and protruding towards the other frame unit; the stop plate and the limiting block extend along the extension direction of the frame unit; the slot includes a baffle located at the dividing line on the other frame unit and bent into the annular channel, and a limiting groove located on the baffle for the corresponding limiting block to be inserted; the baffle abuts against the stop plate and extends along the extension direction of the frame unit. This structure allows for a tighter fit between the insert and the slot, effectively limiting the relative position of the two frame units; simultaneously, the elongated stop plate and baffle increase the strength of the frame unit.
[0016] Preferably, the limiting block is a dovetail structure, and the limiting groove is a dovetail groove. With this type of limiting block and groove, two frame units need to be inserted into each other in the front-to-back direction during installation. The dovetail structure has a self-locking function, which further improves the stability of the connection between the two frame units and prevents loosening during installation and use.
[0017] After adopting the above technical solution, the beneficial effects of this utility model are:
[0018] This utility model, a split-type cable penetration component, solves the problem in the prior art where integral cable penetration components cannot be installed after cable pulling or wiring when equipment or hull-penetrating components are delayed in arrival. The split design allows two frame units to be snapped together from both sides of the cable after it has been pulled or wired, forming a cable threading frame, which is then inserted into the ship's hull structure; thus improving the flexibility and efficiency of cable installation.

Detailed Implementation
[0030] The present invention will be further described below with reference to the accompanying drawings.
[0031] The orientations mentioned in this specification are based on the orientation of the split cable penetration component of this utility model when it is working normally, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.
[0032] like Figure 1 As shown, a split-type cable pass-through component includes a cable pass-through frame 1, which is inserted into the hull structure 4. The cable pass-through frame 1 includes an annular channel formed by a side plate 12 and a flange plate 11 fixed to one end of the annular channel. The annular channel is filled with sealant 2. The cable 3 enters from one end of the annular channel and exits from the other end, thereby achieving the passage and sealing of the cable 3.
[0033] like Figures 2-5 As shown, the cable conduit frame 1 has two dividing lines 5 on the side wall of the annular channel, extending along the direction of the annular channel. These dividing lines 5 divide the cable conduit frame 1 into two abutting frame units. Each frame unit is fixed to the hull structure 4. The side plate 12 and flange plate 11 can be welded to the hull structure 4. This split design allows the two frame units to be snapped together from both sides of the cable 3 after the cable 3 has been pulled or connected, forming the cable conduit frame 1, which is then inserted into the hull structure 4. Welding each frame unit to the hull structure 4 solves the problem of inconvenient installation of integral cable conduits and improves the flexibility of cable 3 installation.
[0034] Furthermore, flange holes are evenly distributed on flange plate 11, and threaded holes are provided on hull structure 4 corresponding to the flange holes. The two are bolted together, allowing the cable guide frame 1 to be detachably fixed to hull structure 4. This fixing method satisfies installation requirements in special scenarios, such as when the hull structure 4 has a thin wall and welding is not possible.
[0035] Furthermore, the outer side of the flange plate 11 has the same geometry as the outer wall of the cable conduit frame 1, and its circumferential dimension is larger than the corresponding dimension of the cable conduit frame 1, forming a radially expanding flange structure. This design can increase the contact area between the flange plate 11 and the hull structure 4, improving the sealing effect and fixing stability.
[0036] By filling the annular channel with sealant 2 and ensuring the tight fit between the flange plate 11 and the hull structure 4, the sealing of the cable penetration can be guaranteed, preventing water, dust, and other contaminants from entering the interior of the hull structure 4 and ensuring the safe operation of the equipment and cables 3.
[0037] In one embodiment, the cross-section of the annular channel is rectangular (e.g., ...). Figure 2 and Figure 3 As shown, the rectangular annular channel has high space utilization, and the straight edges are easy to measure, resulting in high positional accuracy.
[0038] In another embodiment, the cross-section of the annular channel is elliptical (e.g., Figure 4 and Figure 5 (As shown in the diagram); the elliptical annular channel has superior mechanical properties, with its arc-shaped structure dispersing stress and providing stronger resistance to compression and deformation; it also reduces edge damage, eliminating sharp corners and reducing frictional loss during cable threading, making it particularly suitable for fiber optic or high-voltage cables requiring high flexibility; furthermore, it offers better sealing, with the arc-shaped edges adhering more tightly to the sealant, resulting in better waterproofing and dustproofing. Of course, the cross-section of the annular channel can also be circular or other shapes; this embodiment does not impose any limitations on this.
[0039] The positions of the two dividing lines 5 can also be different. Preferably, the two dividing lines 5 are symmetrically arranged on both sides of the annular channel, so that the structures of the two frame units are symmetrical, which makes installation convenient and the force is even.
[0040] The positions of the two dividing lines 5 can be set horizontally (e.g., Figure 2 and Figure 5 As shown in the diagram, the two frame units are divided into two symmetrical frame units. They can also be set vertically (e.g., ...). Figure 4 As shown), the two frame elements are divided into two symmetrical frame elements. They can also be set diagonally (e.g., Figure 3 As shown, the two frame units are divided into two angularly symmetrical frame units.
[0041] like Figure 6 and Figure 7 As shown, in order to ensure the stability of the docking position of the two frame units, a limiting structure 6 is provided on each of the two frame units to restrict their docking position. The limiting structure 6 includes an insert 61 provided on one of the frame units and a slot 62 provided on the other frame unit for the insert 61 to be inserted into. Through the cooperation of the insert 61 and the slot 62, the accurate position of the two frame units during docking can be ensured, thus guaranteeing the stability of the annular channel.
[0042] Furthermore, two limiting structures 6 are provided, located at the positions of the two dividing lines 5 respectively. This further improves the accuracy and stability of the docking of the two frame units.
[0043] like Figure 8 and Figure 9As shown, the insert 61 includes a stop plate 611 located at the dividing line 5 on one of the frame units and bent into the annular channel, and a limiting block 612 located on the stop plate 611 and protruding towards the other frame unit; the stop plate 611 and the limiting block 612 extend along the extension direction of the frame unit. The slot 62 includes a baffle 621 located at the dividing line 5 on the other frame unit and bent into the annular channel, and a limiting groove 622 located on the baffle 621 for the corresponding limiting block 612 to be inserted; the baffle 621 abuts against the stop plate 611 and extends along the extension direction of the frame unit. This structure makes the fit between the insert 61 and the slot 62 tighter, effectively limiting the relative position of the two frame units; at the same time, the elongated stop plate 611 and baffle 621 can increase the strength of the frame unit.
[0044] Figure 8 This is a structural diagram of the insert block 61 and slot 62 of two symmetrical frame units. Figure 9 A structural diagram showing the arrangement of the insert block 61 and slot 62 for two angularly symmetrical frame units.
[0045] The limiting structure 6 described above allows two frame units to interlock, improving their positional accuracy. However, when released, the interlocking connection fails, and they easily detach. To address this issue, in another embodiment, such as... Figure 10 As shown,
[0046] The limiting block 612 has a dovetail structure, and the limiting groove 622 has a dovetail groove. When installing the limiting block 612 and the limiting groove 622 with this structure, two frame units need to be inserted in the front and back directions. The dovetail structure has a self-locking function, which can further improve the stability of the connection between the two frame units and prevent loosening during installation and use.
[0047] The setting of the limiting structure 6, especially the dovetail-structured limiting block 612 and limiting groove 622, can ensure that the docking position of the two frame units is accurate and the connection is stable, thereby improving the structural strength and stability of the entire cable penetration component.
[0048] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
