Description

Technical Field

[0001] This utility model relates to the field of cable installation, and in particular to a sealed cable tray for ships. Background Technology

[0002] Cable systems on medium and large ships typically include power cables, communication cables, and control cables. These cables need to be securely supported and arranged to ensure the normal operation of the ship. Cable trays are commonly used in the engineering field for laying electrical cables. The cables are placed in the cable trays, which serve to protect the cables and regulate their routing.

[0003] Existing cable trays are typically made of alloy plastic and employ a modular structure, consisting of a square box composed of a left side plate, a right side plate, a bottom plate, and a top cover plate. This type of cable tray, assembled from multiple flat plates, is complex to install, leading to cumbersome cable inspection and replacement. Furthermore, existing marine cable trays are mostly land-based and cannot be effectively used on ships, failing to enclose the cables and prevent corrosion. CN219227156U discloses a marine electrical wiring cable tray, which includes a main cable tray and a cover plate. The inner flange of the main cable tray engages with the outer flange of the cover plate. The opening and closing notch of the inner flange and the protrusion of the outer flange interlock, and the connection and locking of the main cable tray and cover plate are achieved by the translational misalignment of the main cable tray and the cover plate, causing the opening and closing notch and the protrusion to mesh. While this type of cable tray allows for quick connection and disassembly without screws, facilitating shipbuilding and maintenance, it has two drawbacks: First, although the interlocking of the inner and outer flanges enables quick connection, during equipment assembly and disassembly, the inner flange of the main cable tray bends inward while the outer flange of the cover plate bends outward, with the inner flange pressing on top of the outer flange. When the cover plate needs to be removed, it must be pulled upward to deform the inner flange upward, and during this process, the inner and outer flanges remain interlocked, making it difficult to separate and potentially damaging the structure. Second, while this type of cable tray primarily addresses the issue of quick connection, it fails to achieve a sealing effect. The overall sealing performance of the cable tray is poor, making it unsuitable for areas with high waterproofing requirements, especially given the high humidity on ships and the potential for seawater to enter the deck due to ship movement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a sealed and corrosion-resistant cable tray for ships that is easy to assemble and disassemble and has good sealing performance.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a sealed cable tray for ships, comprising a lower trough and an upper cover, wherein the lower trough is an integrally bent trough structure; the upper cover is an integrally bent cover structure; the lower trough includes a bottom plate body, both ends of which are bent upward to form bottom plate sidewalls, and the top free end of the bottom plate sidewall is provided with an upward and inwardly bent V-shaped groove, the free end of the V-shaped groove bends outward and upward and then inward and downward to form a C-shaped sealing lip; the upper cover includes a cover plate body, both ends of which are bent downward to form cover plate sidewalls, the bottom free end of the cover plate sidewall bends inward and downward and then outward and upward to form a C-shaped elastic buckle;

[0006] When the upper cover and the lower groove are connected, the C-shaped elastic buckle is engaged in the V-shaped groove, and the two points of the C-shaped elastic buckle and the V-shaped groove are pressed together to form a double seal. A third seal is formed between the C-shaped sealing lip and the inner surface of the cover plate body.

[0007] As a preferred technical solution, the surfaces of the lower tank and the upper cover are provided with a zinc-iron alloy layer.

[0008] As a preferred technical solution, it also includes a tank mounting base, the bottom end of which is provided with a plurality of mounting base fixing holes, the bottom end of the lower tank is placed inside the tank mounting base and is partially surrounded by the tank mounting base, and the lower tank is in contact with the side wall of the tank mounting base and is provided with a limiting structure.

[0009] As a preferred technical solution, a shock-absorbing rubber layer is sandwiched between the bottom end of the lower groove and the groove mounting base.

[0010] As a preferred technical solution, the tank mounting base includes a mounting base base plate, the mounting base fixing holes are provided along the length direction of the mounting base base plate, the two ends of the mounting base base plate are bent upward and extended to provide mounting base sidewalls, and the mounting base base plate and the two mounting base sidewalls form a mounting base cavity for accommodating the lower part of the lower tank.

[0011] As a preferred technical solution, the limiting structure includes a lateral limiting structure and a vertical limiting structure.

[0012] As a preferred technical solution, the lateral limiting structure includes a lateral groove provided along the length direction on the side wall of the base plate and a lateral protrusion provided along the length direction on the side wall of the mounting base, wherein the lateral protrusion can be correspondingly inserted into the lateral groove.

[0013] As a preferred technical solution, the vertical limiting structure includes a vertical groove vertically disposed on the side wall of the base plate and a vertical protrusion vertically disposed on the side wall of the mounting base, wherein the vertical protrusion can be correspondingly inserted into the vertical groove.

[0014] As a preferred technical solution, the groove mounting base is an integrally bent structure.

[0015] As a preferred technical solution, the surface of the tank mounting base is provided with a zinc-iron alloy layer.

[0016] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] By designing the connection between the lower tank and the upper cover, a two-point tight-fitting snap-fit ​​connection is achieved using C-type elastic buckles and V-type grooves. This fit creates a locking connection between the upper cover and the lower tank, ensuring the stability of the connection. Because the C-type elastic buckle and the V-type groove have two points of contact, a double-layer seal is formed at the connection. Furthermore, a third layer of seal is provided between the C-type sealing lip and the upper cover, achieving a three-layer sealing effect at the connection. This provides excellent sealing and is well-suited for areas on ships where cable waterproofing and moisture-proofing requirements are high.

[0018] Since both the lower groove and the upper cover are made of thin plates through integral bending, the structure is easy to process. The plates have sufficient strength and a certain degree of deformability. Furthermore, the C-type elastic buckle is located on the outside of the V-shaped slot. During disassembly and assembly, the C-type elastic buckle can be unlocked from the V-shaped slot by pressing the side wall of the lower groove from the outside to the inside with your hand, which facilitates quick operation of the upper cover.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figure 1 As shown, a sealed cable tray for ships includes an upper cover 10 and a lower trough 20. The upper cover 10 is fastened and fixed to the top opening of the lower trough 20. The two together form a sealed space inside the lower trough 20 for accommodating cables. The two together form a cable tray with good sealing effect and convenient assembly and disassembly.

[0029] See Figure 1 and Figure 2 The lower groove 20 is an integrally bent groove structure, formed by gradually bending a single piece of sheet metal using a forming machine. The lower groove 20 includes a base plate body 21, with both ends of the base plate body 21 extending upwards to form base plate sidewalls 22. The top free end of the base plate sidewall 22 has an upwardly and inwardly bent V-shaped groove 23. The free end of the V-shaped groove 23 bends outwards and upwards, then inwards and downwards to form a C-shaped sealing lip 24. It is made of 2mm-3mm thick stainless steel sheet and integrally formed using bending technology, featuring convenient processing, high strength, and elastic deformation. The V-shaped grooves 23 and C-shaped sealing lips 24 are symmetrically arranged on the left and right sides of the base plate sidewall 22.

[0030] See Figure 1 and Figure 3The upper cover 10 is an integrally bent cover structure, formed by gradually bending a single piece of sheet metal using a forming machine. The upper cover 10 includes a cover plate body 11, with both ends of the cover plate body 11 bent downwards to form cover plate sidewalls 12. The bottom free end of the cover plate sidewall 12 bends inwards and downwards, then outwards and upwards to form a C-shaped elastic buckle 13. It is made of 2mm-3mm thick stainless steel sheet, integrally formed using bending technology, and features convenient processing, high strength, and elastic deformation. The C-shaped elastic buckles 13 are symmetrically arranged on both sides of the cover plate sidewall 12.

[0031] After the lower tank body 20 and the upper cover body 10 are bent and formed, a zinc-iron alloy layer is formed on the surface of the lower tank body 20 and the upper cover body 10 by hot-dip galvanizing process, which improves the anti-corrosion effect of the plate surface.

[0032] When the upper cover 10 is fastened and fixed to the lower groove 20, the C-shaped elastic buckle 13 engages with the V-shaped groove 23, and the C-shaped elastic buckle 13 and the V-shaped groove 23 are pressed together at two points to form a double seal. A third seal is formed between the C-shaped sealing lip 24 and the inner surface of the cover plate body 11. (See attached diagram for details.) Figure 4 and Figure 5 .

[0033] See Figure 4 When the C-type elastic buckle 13 is in its natural state (i.e., before it is engaged in the V-shaped groove 23), the bending curvature of the C-type elastic buckle 13 is small (see state). Figure 4 (Dashed line in the middle) The C-shaped elastic buckle 13 is larger than the space of the V-shaped groove 23. When the C-shaped elastic buckle 13 is engaged in the V-shaped groove 23, the free end of the C-shaped elastic buckle 13 will undergo adaptive bending deformation due to the spatial restriction of the V-shaped groove 23. At this time, the bending curvature of the C-shaped elastic buckle 13 increases. Under the action of its own structural elastic deformation, the C-shaped elastic buckle 13 will have two points abutting and pressing against the surface of the V-shaped groove 23, realizing a double-layer seal. At the same time, since the two points of the C-shaped elastic buckle 13 are tightly abutting against the V-shaped groove 23, a locking engagement is formed between the two, which can ensure the connection stability between the upper cover 10 and the lower groove 20. In addition, the tight cooperation of multiple points will also limit the position of the upper cover 10, so that the upper cover 10 will not slide freely relative to the lower groove 20. After the buckle connection is completed, the C-shaped sealing lip 24 is in contact with the inner surface of the cover body 11, realizing a third layer of seal.

[0034] Figure 5 At point I, the lower side of the C-shaped elastic buckle 13 presses against one side of the V-shaped groove 23, serving as the first layer of sealing. Figure 5At point II, the upper side of the C-shaped elastic buckle 13 abuts against and presses against the other side of the V-shaped groove 23, serving as a second layer of sealing. Figure 5 At point III, the C-shaped sealing lip 24 contacts the inner surface of the cover plate body 11, serving as a third layer of seal. This three-layer seal at the mating surface between the upper cover body 10 and the lower groove body 20 achieves an optimal sealing effect, making it well-suited for use in areas on ships with high sealing requirements.

[0035] The lower groove 20 described in this application is formed by bending a thin plate. The free end of the plate can have a certain degree of deformation, which is conducive to the disassembly and assembly of the upper cover 10. Specifically, before disassembling the upper cover 10, the upper part of the two side walls of the upper cover 10 is pressed from the outside to the inside by hand. When the C-shaped elastic buckle 13 is aligned with the V-shaped groove 23, the hand is released, the side wall of the lower groove 20 returns to its original deformation, and the V-shaped groove 23 squeezes the C-shaped elastic buckle 13 outward. The V-shaped groove 23 and the C-shaped elastic buckle 13 are tightly fastened together. When it is necessary to repair the cable, the upper part of the two side arms of the lower groove 20 is pressed from the outside to the inside by hand to release the C-shaped elastic buckle 13 from the V-shaped groove 23. Then the upper cover 10 can be removed. The structural design of this application is conducive to disassembly and maintenance.

[0036] See Figure 1 The cable tray also includes a trough mounting base 30, which is an auxiliary component for fixing the lower trough 20 to a deck or other platform. In use, the lower trough 20 is fixed to the deck or other platform by the trough mounting base 30, and then fixed inside the trough mounting base 30. This fixing method avoids drilling holes in the lower trough 20 and can ensure the sealing of the lower trough 20.

[0037] See Figure 6 The tank mounting base 30 is an integrally bent structure with a zinc-iron alloy layer on its surface. The bottom end of the tank mounting base 30 has several mounting holes, allowing it to be fixedly connected with bolts. The bottom end of the lower tank 20 is placed inside the tank mounting base 30 and partially surrounded by it. The lower tank 20 contacts the side wall of the tank mounting base 30 and is provided with a limiting structure. A shock-absorbing rubber layer 31 is sandwiched between the bottom end of the lower tank 20 and the tank mounting base 30. The shock-absorbing rubber layer 31 can reduce noise and vibration transmitted from the deck to the lower tank 20 and fill the gap between the lower tank 20 and the tank mounting base 30, facilitating a stable connection between them.

[0038] See Figure 6The groove mounting base 30 includes a mounting base base plate 32. The mounting base fixing holes are provided along the length direction of the mounting base base plate 32. The two ends of the mounting base base plate 32 are bent upward and extended to provide mounting base sidewalls 33. The mounting base base plate 32 and the two mounting base sidewalls 33 form a mounting base cavity for accommodating the lower part of the lower groove 20.

[0039] See Figure 6 The limiting structure includes a lateral limiting structure 34 for limiting the vertical position of the lower groove 20 and a vertical limiting structure 35 for limiting the length position of the lower groove 20. The lateral limiting structure 34 and the vertical limiting structure 35 cooperate to limit and connect the lower groove 20, fixing it within the groove mounting base 30. In this embodiment, multiple lateral limiting structures 34 and vertical limiting structures 35 may be provided. The lateral limiting structure 34 can be directly formed by bending, and the vertical limiting structure 35 can be formed by extrusion.

[0040] See Figure 6 The lateral limiting structure 34 includes a lateral groove on the side wall 22 of the base plate along the length direction and a lateral protrusion on the side wall 33 of the mounting base along the length direction. The lateral protrusion can be correspondingly inserted into the lateral groove. The vertical limiting structure 35 includes a vertical groove on the side wall 22 of the base plate and a vertical protrusion on the side wall 33 of the mounting base. The vertical protrusion can be correspondingly inserted into the vertical groove.

[0041] The installation method in this embodiment is as follows:

[0042] First, the tank mounting base 30 is fixed to the deck or other platform with screws, and a layer of shock-absorbing rubber 31 is laid on the inner surface of the tank mounting base 30. Then, the lower tank 20 is fixed inside the tank mounting base 30 by a limiting structure. Next, the cable is laid inside the lower tank 20. After the cable is laid, the upper cover 10 is sealed and fastened to the lower tank 20. Finally, both ends are wrapped with waterproof tape, foam glue, or glass glue. Fiberglass cloth is used for sealing; when connecting the upper cover 10, first press the upper part of the two arms of the lower groove 20 from the outside to the inside with your hands, and then fasten the upper cover 10 from top to bottom. When the C-shaped elastic buckle 13 is aligned with the V-shaped groove 23, release your hands, the side wall of the lower groove 20 will return to its original deformation, the V-shaped groove 23 will press the C-shaped elastic buckle 13 outward, and the V-shaped groove 23 and the C-shaped elastic buckle 13 will be tightly fastened together, thus achieving a three-layer seal at the same time;

[0043] When cable repair is needed, first press the upper part of both arms of the lower groove 20 from the outside to the inside with your hands to release the C-shaped elastic buckle 13 from the V-shaped slot 23, and then remove the upper cover 10. The disassembly and assembly of the upper cover 10 is relatively convenient and will not damage its own structure.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
