Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, and more specifically, to a high-strength cable protection trough. Background Technology

[0002] With societal development and the continuous upgrading of power systems and communication networks, the requirements for the high-temperature resistance, protective strength, and safety of cable trays are constantly increasing. Currently, ordinary cable trays on the market have poor high-temperature resistance. After long-term use in high-temperature environments, cable trays are prone to deformation, significantly affecting their service life. Their thermal insulation performance is also relatively poor. For the installation of high-voltage, high-current cables that generate significant heat, accidental contact with the exposed cable tray can easily cause burns. Under high temperatures, the risk of leakage from the cable tray also increases, posing a safety hazard. Furthermore, ordinary cable trays lack cable separation structures, leading to the mixing and compression of strong and weak current wires. Overloaded wires can easily cause short circuits and fires, posing a significant safety hazard. Moreover, ordinary cable trays have insufficient pressure resistance and weak load-bearing capacity. When subjected to external pressure, the internal cables can be directly squeezed together, increasing the risk of tangled strong and weak current wires. The cable tray itself is also prone to cracking or damage due to compression, resulting in low safety performance and inconvenience in use. Utility Model Content

[0003] This invention overcomes the shortcomings of existing technologies, such as poor heat insulation performance of cable trays, and the risk of burns to personnel when cable trays are exposed and contain cables with high heat generation, resulting in poor safety. It provides a high-strength cable protection cable tray that improves heat insulation performance and prevents accidental burns.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-strength cable protection trough, including: a base and an upper cover that is snapped into the base. The base is provided with a plurality of first cable trays for placing or fixing cables. The upper cover is provided with a heat insulation cavity, which is located at the opening of the first cable tray or around the first cable tray.

[0005] The top cover snaps into the base. The base has several first-line cable slots. In use, the top cover is opened, the cable is placed or secured in one of the first-line cable slots, and then the top cover is installed to complete the cable arrangement. The number of first-line cable slots depends on the situation, but multiple slots are preferred for cable separation. To insulate cables with high heat generation, a heat insulation cavity is provided inside the top cover. This cavity creates a hollow structure inside the top cover, filled with air. Air's thermal conductivity is much lower than that of the top cover itself, thus blocking heat from the cable and preventing a large amount of heat from being directly conducted to the outer surface of the top cover. This reduces the operating temperature of the outer surface of the top cover and prevents burns from accidental contact. Structurally, the top cover has at least two plate-like structures, with the heat insulation cavity located between them. This improves the overall compressive strength and resistance of the top cover. After compression, the compressed area deforms, reducing the space of the insulation cavity and providing a certain buffering effect. Within a smaller pressure range, the inner cover plate will not be compressed, which also largely prevents the cables from being squeezed and tangled, avoiding voltage overload, overheating, or fire caused by the cables being squeezed, thus improving the safety of the cable tray. Under extreme external force, the outer cover plate bears the main pressure. With the protection of the outer cover plate, the probability of the inner cover plate being squeezed and broken is also relatively small, effectively preventing the cables from being exposed due to the cracking of the cover, thus improving the protection effect of the cables and making them safer to use.

[0006] Preferably, it also includes a wire trough support connected to the base, and the wire trough support is provided with a plurality of second wire trough compartments.

[0007] A cable tray bracket is installed on the base, and a second cable tray compartment is installed on the cable tray bracket, so that the first cable tray compartment and the second cable tray compartment are separated from each other, thereby separating the cables placed in the first cable tray compartment and the second cable tray compartment respectively, further preventing the cables from crossing and tangling together, and preventing the cables from getting tangled, overheating and catching fire.

[0008] Preferably, the cable tray support is provided with a tree-shaped support portion, and the tree-shaped support portion is provided with at least two support ends, and the second cable tray compartments are respectively disposed on the support ends.

[0009] The tree-shaped support section is used to increase the number of second cable trays that can be installed. Each branch of the tree-shaped support section has a support end, and each support end has a second cable tray, thereby increasing the number of second cable trays and allowing the cable tray to hold and separate more cables.

[0010] Preferably, the second line hopper is C-shaped or U-shaped.

[0011] The second cable tray is designed as a C-shape or U-shape, with an arc-shaped support section that fits the cable better and provides better support.

[0012] Preferably, the base is provided with a first snap-fit ​​part, the wire groove bracket is provided with a second snap-fit ​​part that cooperates with the first snap-fit ​​part, and at least two first wire groove compartments are provided, which are respectively provided on both sides of the first snap-fit ​​part.

[0013] The cable tray bracket is snapped into the base, allowing the cable tray bracket to be disassembled for easier use and replacement with cable tray brackets of different specifications. This facilitates the installation of different numbers and sizes of second cable tray compartments, while the first cable tray compartments are positioned on both sides of the first snap-fit ​​part, resulting in a more compact space arrangement.

[0014] Preferably, the first cable tray includes two clamping plates connected to the base and symmetrically arranged. The clamping plates have a clearance portion on their outer side. The base has abutment portions on both sides. The abutment portions are connected to the clearance portions to form a slot. The upper cover has a first claw on both sides that cooperates with the slot. The first claw is located on the inner side of the upper cover.

[0015] Each first cable tray consists of two clamping plates, which are respectively mounted on the base and positioned opposite each other. During use, the cable is clamped between the two clamping plates. Each clamping plate has a clearance portion on its outer side. The two outermost clearance portions on both sides of the base connect to the abutment portion, forming a slot. The first claw of the upper cover engages with the slot, thus achieving a latching connection between the upper cover and the base. Furthermore, between adjacent first cable trays, two clearance portions form a larger clearance area. This clearance area is used to install the latching structure between the cable tray support and the base, i.e., to avoid the first and second latching portions. Further, the abutment portion is a plate-like structure.

[0016] Preferably, the first locking part is T-shaped and includes a vertical plate connected to the base and a first horizontal plate connected to the vertical plate. The second locking part includes a second horizontal plate disposed at the bottom of the wire groove bracket and second claws disposed on both sides of the horizontal plate. The first locking part is locked between the second claws. The second horizontal plate abuts against the first horizontal plate. The second claws abut against both sides of the first horizontal plate.

[0017] The first locking part is T-shaped, specifically including a vertical plate and a first horizontal plate. The second locking part includes a second horizontal plate and second claws disposed on both sides of the second horizontal plate. A locking position is formed between the second horizontal plate and the two second claws. The first horizontal plate is locked in the locking position. That is, after the first locking part and the second locking part are locked, the first horizontal plate is located below the second horizontal plate and between the two second claws. In order to maintain the stability of the cable tray support and control the overall size of the second locking part, the top surface of the first horizontal plate abuts against the second horizontal plate after locking, and the two sides of the first horizontal plate abut against the second claws respectively, thereby preventing the second locking part and the cable tray support from shaking.

[0018] Preferably, the clamping plate includes a connecting part connected to the base and an arc-shaped clamping plate connected to the connecting part, and the clearance part is disposed on the connecting part.

[0019] The clearance section is set on the connecting part, that is, on the outside of the connecting part. The clamping plate is connected to the connecting part and is used to fix the cable. Specifically, the connecting part is preferably set as a plate-shaped structure, and the clearance section is set by setting a bend or fold.

[0020] Preferably, the upper cover is semi-enclosed and covers both sides and the top surface of the first line slot.

[0021] The top cover is designed to be semi-enclosed, increasing the opening angle of the base and making it easier to place cables.

[0022] Preferably, the heat insulation cavity extends to both ends of the upper cover.

[0023] The insulation cavity extends to both ends of the top cover, increasing the coverage area of ​​the insulation cavity, improving the insulation effect, enhancing the protective effect of the top cover, and increasing the overall strength of the cable tray.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] A heat insulation cavity is provided inside the top cover, and the heat insulation cavity is arranged around the first cable tray or at the opening of the first cable tray. When in use, the cable is placed in the first cable tray, and the heat insulation cavity can block the cable, thereby blocking the heat generated by the cable and preventing excessive heat from being transferred to the outer surface of the top cover. This prevents burns from accidental contact. The heat insulation cavity also improves the overall strength and compression resistance of the cable tray, making the overall use of the cable tray safer and reducing the risk of leakage.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0033] Example 1

[0034] like Figure 1 As shown, a high-strength cable protection trough includes: a base 1 and an upper cover 2 that snaps into the base 1. The base 1 is provided with a plurality of first cable trays 3 for placing or fixing cables. The upper cover 2 is provided with a heat insulation cavity 4, which is located at the opening of the first cable trays 3 or surrounds the first cable trays 3.

[0035] The upper cover 2 is snapped into the base 1. The base 1 has several first wire slots 3. In use, the upper cover 2 is opened, and the cable is placed or fixed in the first wire slot 3. Then, the upper cover 2 is installed to complete the cable arrangement. The number of first wire slots 3 depends on the situation, but multiple slots are preferred to separate the cables. To insulate cables with high heat generation, a heat insulation cavity 4 is provided inside the upper cover 2. This heat insulation cavity 4 creates a hollow structure inside the upper cover 2. During use, the heat insulation cavity 4 is filled with air. Air has a much lower thermal conductivity than the upper cover 2 itself, thus blocking the heat from the cable and preventing a large amount of heat from being directly conducted to the outer surface of the upper cover 2. This reduces the operating temperature of the outer surface of the upper cover 2 and prevents burns from accidental contact. With the heat insulation cavity 4, the upper cover 2 has at least two plate-like structures, with the heat insulation cavity 4 located between these two plate-like structures. This improves the overall compressive strength and resistance of the upper cover 2. When the plate is compressed, the compressed area deforms, and the space of the heat insulation cavity 4 becomes smaller, achieving a certain buffering effect. Within a small pressure range, the inner cover plate of the upper cover 2 will not be compressed, which also largely avoids the cables from being compressed and tangled together, and prevents voltage overload, overheating, or fire caused by the cables being compressed, thus improving the safety of the cable tray. When subjected to extreme external force, the outer cover plate of the upper cover 2 bears the main pressure. With the protection of the outer cover plate of the upper cover 2, the probability of the inner cover plate of the upper cover 2 being compressed and broken is also relatively small, which fully avoids the situation where the upper cover 2 breaks and the cables are exposed. The protection effect of the cables is also improved, making it safer to use.

[0036] The beneficial effects of this embodiment are as follows: A heat insulation cavity 4 is provided inside the upper cover 2, and the heat insulation cavity 4 is arranged around the first wire trough 3, or is located at the opening of the first wire trough 3. When in use, the cable is placed in the first wire trough 3, and the heat insulation cavity 4 can block the cable, thereby blocking the heat generated by the cable, preventing excessive heat from being transferred to the outer surface of the upper cover 2, and preventing burns caused by accidental contact. The setting of the heat insulation cavity 4 also improves the overall strength and compression resistance of the wire trough, making the overall use of the wire trough safer and reducing the risk of leakage.

[0037] Example 2

[0038] This embodiment further defines the features of Embodiment 1, and its difference from Embodiment 1 lies in:

[0039] like Figure 1-3As shown, it also includes a wire trough bracket 5 connected to the base 1, and the wire trough bracket 5 is provided with several second wire trough compartments 6. The wire trough bracket 5 is provided with a tree-shaped support part 7, and the tree-shaped support part 7 is provided with at least two support ends, and the second wire trough compartments 6 are respectively provided on the support ends. The second wire trough compartments 6 are generally C-shaped or U-shaped. The base 1 is provided with a first snap-fit ​​part 8, and the wire trough bracket 5 is provided with a second snap-fit ​​part 9 that cooperates with the first snap-fit ​​part 8. At least two first wire trough compartments 3 are provided, and they are respectively provided on both sides of the first snap-fit ​​part 8. The first wire trough compartment 3 includes two clamping plates 10 connected to the base 1 and symmetrically arranged. The clamping plates 10 are provided with a clearance part 11 on the outer side. The base 1 is provided with abutment parts 12 on both sides, and the abutment parts 12 are connected to the clearance parts 11 to form a slot 13. The upper cover 2 is provided with a first claw 14 on both sides that cooperates with the slot 13. The first claw 14 is located on the inner side of the upper cover 2.

[0040] A cable tray bracket 5 is installed on the base 1, and a second cable tray compartment 6 is installed on the cable tray bracket 5, thus separating the first cable tray compartment 3 and the second cable tray compartment 6. This further prevents the cables from crossing and tangling, avoiding overheating and fire caused by cable tangling. A tree-shaped support part 7 is provided to increase the number of second cable tray compartments 6 that can be installed. Each branch of the tree-shaped support part 7 has a support end, and each support end has a second cable tray 6, thereby increasing the number of second cable tray compartments 6 and allowing the cable tray to hold and separate more cables. The second cable tray compartment 6 is designed to be C-shaped or U-shaped, with an arc-shaped support part, which fits the cable better and provides better support. The cable tray bracket 5 is snapped into the base 1, allowing the cable tray bracket 5 to be disassembled, making it easier to use and replace with different specifications of cable tray bracket 5, thus allowing for the installation of different numbers and sizes of second cable tray compartments 6. At the same time, the first cable tray compartments 3 are respectively set on both sides of the first snap-fit ​​part 8, resulting in a more compact space arrangement. Each first cable tray 3 consists of two clamping plates 10, which are respectively mounted on the base 1 and positioned opposite each other. During use, the cable is clamped between the two clamping plates 10. Each clamping plate 10 has an outer clearance portion 11. The two outermost clearance portions 11 on both sides of the base 1 connect to the abutment portion 12, forming a slot 13 between them. The first claw 14 of the upper cover 2 engages with the slot 13, thus achieving the engagement between the upper cover 2 and the base 1. Furthermore, between adjacent first cable trays 3, the two clearance portions 11 form a large clearance area. This clearance area is used to set up the engagement structure between the cable tray support 5 and the base 1, i.e., to avoid the first engagement portion 8 and the second engagement portion 9. Further, the abutment portion 12 has a plate-like structure.

[0041] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0042] Example 3

[0043] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0044] like Figure 1-3 As shown, the first latching part 8 is T-shaped and includes a vertical plate 15 connected to the base 1 and a first horizontal plate 16 connected to the vertical plate 15. The second latching part 9 includes a second horizontal plate 17 disposed at the bottom of the wire groove bracket 5 and second claws 18 respectively disposed on both sides of the horizontal plate. The first latching part 8 latches between the second claws 18, the second horizontal plate 17 abuts against the first horizontal plate 16, and the second claws 18 abut against both sides of the first horizontal plate 16 respectively. The clamping plate 10 includes a connecting part 19 connected to the base 1 and an arc-shaped clamping plate 20 connected to the connecting part 19. A clearance part 11 is disposed on the connecting part 19. The upper cover 2 is semi-enclosed and covers both sides and the top surface of the first wire groove compartment 3. The heat insulation cavity 4 extends to both ends of the upper cover 2.

[0045] The first locking part 8 is T-shaped and specifically includes a vertical plate 15 and a first horizontal plate 16. The second locking part 9 includes a second horizontal plate 17 and second claws 18 disposed on both sides of the second horizontal plate 17. A locking position is formed between the second horizontal plate 17 and the two second claws 18. The first horizontal plate 16 is locked in the locking position. That is, after the first locking part 8 and the second locking part 9 are locked, the first horizontal plate 16 is located below the second horizontal plate 17 and between the two second claws 18. In order to maintain the stability of the wire trough bracket 5 and control the overall size of the second locking part 9, the top surface of the first horizontal plate 16 abuts against the second horizontal plate 17 after locking, and the two sides of the first horizontal plate 16 abut against the second claws 18 respectively, thereby preventing the second locking part 9 and the wire trough bracket 5 from shaking. An air-relief portion 11 is provided on the connecting portion 19, i.e., on the outer side of the connecting portion 19. The clamping plate 10 is connected to the connecting portion 19 and is used to fix the cable. Specifically, the connecting portion 19 is preferably designed as a plate-like structure, and the air-relief portion 11 is provided by setting a bend or fold. The upper cover 2 is set in a semi-enclosed shape to increase the opening angle of the base 1, making it easier to place the cable. The heat insulation cavity 4 extends to both ends of the upper cover 2, increasing the coverage area of ​​the heat insulation cavity 4, improving the heat insulation effect, improving the protective effect of the upper cover 2, and improving the overall strength of the cable tray.

[0046] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0047] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
