Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and specifically relates to a waterproof cable trench cover. Background Technology

[0002] Traditional cable trench covers are precast concrete slabs that are directly installed on the trench walls without any connection between them. Because a tight fit between the covers is impossible during installation, gaps remain. These gaps lack waterproofing, and rainwater seeping in is currently primarily drained through drainage channels at the bottom of the trench to a centralized drainage point. However, this method poses risks such as excessive water accumulation and poor drainage, potentially leading to water damage to the cables. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a waterproof cable trench cover, which solves the problem of the risk of cables being soaked in water in the existing solution, and prevents water from flowing into the cable trench through the gaps in the cable trench cover. The structure and construction are relatively simple.

[0004] According to the technical solution of this utility model, this utility model provides a waterproof cable trench cover, including a cable trench cover body, a positive U-shaped groove component, and an inverted U-shaped groove component. The positive U-shaped groove component and the inverted U-shaped groove component are respectively located on both sides of the cable trench cover body. Both the positive U-shaped groove component and the inverted U-shaped groove component are profiles, and the cable trench cover body is a concrete slab. When the cable trench cover body is horizontal, the positive U-shaped groove component forms an upward-opening positive U-shaped groove, and the outer edge of the positive U-shaped groove component is an upward-extending positive U-shaped groove cantilever. The inverted U-shaped groove component forms a downward-opening inverted U-shaped groove, and the outer edge of the inverted U-shaped groove component is a downward-extending inverted U-shaped groove cantilever. Between two adjacent waterproof cable trench covers, the positive U-shaped groove cantilever is inserted into the inverted U-shaped groove, and the inverted U-shaped groove cantilever is inserted into the positive U-shaped groove.

[0005] In some embodiments, an S-shaped gap is formed between two adjacent waterproof cable trench covers, between the interlocking positive U-shaped groove and the inverted U-shaped groove.

[0006] In some implementations, after two adjacent waterproof cable trench covers are inserted together, the top surfaces of the two waterproof cable trench covers are flush.

[0007] In some embodiments, in a waterproof cable trench cover, a positive U-shaped groove support plate and an inverted U-shaped groove support plate are respectively formed at the bottom of the positive U-shaped groove component and the bottom of the inverted U-shaped groove component. The positive U-shaped groove support plate and the inverted U-shaped groove support plate are flush with each other and extend relative to each other. The positive U-shaped groove support plate and the inverted U-shaped groove support plate are both fitted and fixed to the main body of the cable trench cover plate.

[0008] In some embodiments, the profile cross-sectional shape of the U-shaped slot component further includes an inner U-shaped slot plate and a bottom U-shaped slot plate. The inner U-shaped slot plate and the cantilever of the U-shaped slot are parallel, and the bottom U-shaped slot plate is located below the inner U-shaped slot plate and the cantilever of the U-shaped slot. The inner U-shaped slot plate, the bottom U-shaped slot plate, and the cantilever of the U-shaped slot are sequentially connected to form a U-shaped slot. The inner U-shaped slot plate is in contact with the side of the cable trench cover body, and the inner U-shaped slot plate is perpendicular to the U-shaped slot support plate. The inverted U-shaped groove component is directly connected; the profile cross-section also includes an inverted U-shaped groove inner plate and an inverted U-shaped groove bottom plate. The inverted U-shaped groove inner plate and the inverted U-shaped groove cantilever are parallel. The inverted U-shaped groove bottom plate is located below the inverted U-shaped groove inner plate and the inverted U-shaped groove cantilever. The inverted U-shaped groove inner plate, the inverted U-shaped groove bottom plate, and the inverted U-shaped groove cantilever are connected in sequence to form an inverted U-shaped groove. The inverted U-shaped groove inner plate is attached to the side of the cable trench cover body. The inverted U-shaped groove inner plate is perpendicularly connected to the inverted U-shaped groove support plate.

[0009] In some implementations, the sum of the height of the cantilever of the U-shaped groove and the thickness of the bottom plate of the U-shaped groove is not greater than the height of the inner plate of the U-shaped groove; the sum of the height of the cantilever of the inverted U-shaped groove and the thickness of the bottom plate of the inverted U-shaped groove is not greater than the height of the inner plate of the inverted U-shaped groove.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] This utility model's waterproof cable trench cover uses a splicing method, with a U-shaped groove at the splicing position of the cable trench cover. This creates an S-shaped area at the connection between the two cover plates, achieving a seal and preventing rainwater from flowing into the cable trench through the gaps between the cable trench covers, thus reducing the possibility of water accumulation in the cable trench. Furthermore, the cable trench cover of this solution has a simple plug-in connection interface, making it easy to disassemble when inspecting the cables inside the cable trench. In addition, the cable trench cover of this solution is formed from profiles and concrete, resulting in a simple process, low cost, and a reliable structure with stable performance.

[0017] This utility model provides a waterproof cable trench cover that solves the problem of the risk of cables being soaked in water in existing solutions. It prevents water from flowing into the cable trench through the gaps in the cable trench cover, reduces the possibility of water accumulation in the cable trench, and has a relatively simple structure and construction.

[0018] Please see Figures 1 to 3 This utility model discloses a waterproof cable trench cover, comprising a cable trench cover body 1, a U-shaped groove component 2, and an inverted U-shaped groove component 3, which are located on the two side edges of the cable trench cover body 1. Both the U-shaped groove component 2 and the inverted U-shaped groove component 3 are profiles, such as steel profiles or steel plates welded onto steel profiles. The cable trench cover body 1 is a concrete slab, for example, cast between the U-shaped groove component 2 and the inverted U-shaped groove component 3. Optionally, the U-shaped groove component 2 and the inverted U-shaped groove component 3 are first welded together with reinforcing bars or other structures before concrete is poured to make the overall structure more robust; alternatively, the concrete slab of the cable trench cover body 1 is prefabricated using appropriate molds and then fixedly connected to the U-shaped groove component 2 and the inverted U-shaped groove component 3 by means such as bonding or bolting.

[0019] With the cable trench cover body 1 in a horizontal state, the positive U-shaped slot 2 forms a positive U-shaped slot with the opening facing upward, and the outer edge of the positive U-shaped slot 2 is a positive U-shaped slot cantilever 21 extending upward; the inverted U-shaped slot 3 forms an inverted U-shaped slot with the opening facing downward, and the outer edge of the inverted U-shaped slot 3 is an inverted U-shaped slot cantilever 31 extending downward.

[0020] Between two adjacent waterproof cable trench covers, a U-shaped cantilever 21 is inserted into an inverted U-shaped groove, and an inverted U-shaped cantilever 31 is inserted into a U-shaped groove. Specifically, the height and thickness of the U-shaped cantilever 21 match (or are slightly smaller than) the internal dimensions of the inverted U-shaped groove, and the height and thickness of the inverted U-shaped cantilever 31 match (or are slightly smaller than) the internal dimensions of the U-shaped groove. After insertion, an S-shaped structure (a tight insertion structure or a labyrinth structure) is formed, which seals the joint and prevents external water from seeping under the waterproof cable trench cover.

[0021] Preferably, an S-shaped seam is formed between two adjacent waterproof cable trench covers, between the interlocking positive U-shaped groove member 2 and the inverted U-shaped groove member 3. For example... Figure 3As shown, the two waterproof cable trench covers are not tightly interlocked, but rather have a narrow S-shaped gap. Furthermore, the S-shape of the S-shaped gap is horizontal, with the horizontal width of the cross-section being much smaller than its vertical height. This S-shaped gap structure is sufficient to meet waterproofing requirements, effectively preventing rainwater from flowing into the area beneath the cover through the gap. It also allows for easy interlocking and disassembly, eliminating the need for additional connecting structures or asphalt paving.

[0022] Preferably, after two adjacent waterproof cable trench covers are inserted together, the top surfaces of the two waterproof cable trench covers are flush, which facilitates on-site maintenance and operation using the cable trench. More specifically, the upper and lower end faces of the positive U-shaped groove component 2 and the inverted U-shaped groove component 3 do not exceed (preferably are flush with) the upper and lower surfaces of the cable trench cover body 1, forming an integral flat plate structure. Combined with the size design of the positive U-shaped groove component 2 and the inverted U-shaped groove component 3, the two waterproof cable trench covers are flush.

[0023] Please see Figure 2 More specifically, in a waterproof cable trench cover, the bottom of the U-shaped groove component 2 and the bottom of the inverted U-shaped groove component 3 are respectively provided with a U-shaped groove support plate 22 and an inverted U-shaped groove support plate 32. The U-shaped groove support plate 22 and the inverted U-shaped groove support plate 32 are flush and extend relative to each other. Both the U-shaped groove support plate 22 and the inverted U-shaped groove support plate 32 are fitted and fixed to the cable trench cover body 1 (the bottom of the cable trench cover body 1 forms a matching groove for fitting). The U-shaped groove support plate 22 and the inverted U-shaped groove support plate 32 in this solution can make the connection between the U-shaped groove component 2 and the inverted U-shaped groove component 3 and the cable trench cover body 1 more stable, especially when the U-shaped groove component 2 and the inverted U-shaped groove component 3 are metal profiles and the cable trench cover body 1 is a concrete structure.

[0024] Furthermore, the profile cross-sectional shape of the U-shaped slot component 2 also includes an inner plate 23 and a bottom plate 24. The inner plate 23 and the cantilever 21 are parallel. The bottom plate 24 is located below the inner plate 23 and the cantilever 21. The inner plate 23, the bottom plate 24, and the cantilever 21 are connected in sequence to form a U-shaped structure, i.e., a U-shaped slot. The inner plate 23 is attached to the side of the cable trench cover body 1. The inner plate 23 is perpendicularly connected to the support plate 22. In the illustrated embodiment, the U-shaped slot 2 is located on the left side of the cable trench cover body 1. The cross-section of the U-shaped slot 2 is a horizontally placed F-shape. The U-shaped slot support plate 22 is flush with the U-shaped slot bottom plate 24 and the U-shaped slot support plate 22 is located on the right side.

[0025] Similarly, the profile cross-sectional shape of the inverted U-shaped slot component 3 also includes an inverted U-shaped slot inner plate 33 and an inverted U-shaped slot bottom plate 34. The inverted U-shaped slot inner plate 33 and the inverted U-shaped slot cantilever 31 are parallel. The inverted U-shaped slot bottom plate 34 is located below the inverted U-shaped slot inner plate 33 and the inverted U-shaped slot cantilever 31. The inverted U-shaped slot inner plate 33, the inverted U-shaped slot bottom plate 34, and the inverted U-shaped slot cantilever 31 are connected in sequence to form a U-shaped structure, i.e., an inverted U-shaped slot. The inverted U-shaped slot inner plate 33 is attached to the side of the cable trench cover body 1. The inverted U-shaped slot inner plate 33 is perpendicularly connected to the inverted U-shaped slot support plate 32. In the illustrated embodiment, the inverted U-shaped slot 3 is located on the right side of the cable trench cover body 1. The cross-section of the inverted U-shaped slot 3 is a horizontal S-shape. The inverted U-shaped slot support plate 32 is flush with the lower end of the inverted U-shaped slot inner plate 33 and the inverted U-shaped slot support plate 32 is located on the left side.

[0026] In the aforementioned specific structure, both the positive U-shaped slot component 2 and the inverted U-shaped slot component 3 possess complete U-shaped structures, rather than forming a U-shaped structure through the outer cantilever of the profile and the side of the cable trench cover body 1. This overall U-shaped structure fully utilizes the structural strength, toughness, and precision of the profile, ensuring convenient processing and forming while meeting the structural fit requirements. Simultaneously, the inner plates and support plates in the positive U-shaped slot component 2 and the inverted U-shaped slot component 3 form a structure similar to angle steel, enabling a larger bonding area with the cable trench cover body 1 and providing structural support, thus increasing the overall structural strength.

[0027] For more details, please refer to Figure 2 , Figure 3 The sum of the height of the U-shaped slot cantilever 21 and the thickness of the U-shaped slot base plate 24 is no greater than the height of the U-shaped slot inner plate 23; the sum of the height of the inverted U-shaped slot cantilever 31 and the thickness of the inverted U-shaped slot base plate 34 is no greater than the height of the inverted U-shaped slot inner plate 33. This allows the desired S-shaped structure to be formed at the insertion point, ensuring that the U-shaped slot component 2 and the inverted U-shaped slot component 3 are compatible, making the two waterproof cable trench covers flush and relatively stable after insertion.

[0028] In summary, the waterproof cable trench cover of this utility model adopts a splicing method, with a U-shaped groove at the splicing position of the cable trench cover. This creates an S-shaped area at the connection between the two cover plates, achieving a seal and preventing rainwater from flowing into the cable trench through the gaps between the cable trench covers, thus reducing the possibility of water accumulation in the cable trench. Furthermore, the plug-in connection interface of the cable trench cover in this solution is simple, and the cable trench cover is easy to disassemble during cable maintenance inside the cable trench. Additionally, the cable trench cover of this solution is formed from profiles and concrete, resulting in a simple process, low cost, and a robust structure with stable performance. While some existing cable trench covers require asphalt paving, the structure of this solution eliminates the need for asphalt, avoiding environmental and fire resistance risks. It meets waterproofing requirements while facilitating the opening of the cable trench during later operation and maintenance, making it particularly suitable for large-scale open-air deployments in scenarios with strict fire prevention and maintenance requirements, such as substations.
