Technical Field

[0001] This utility model relates to the field of substation cable laying technology, specifically to a cross-clamping cable trench box of different types. Background Technology

[0002] With the acceleration of urbanization, electricity demand continues to grow, and the requirements for power infrastructure are also increasing. Laying different types of cables in separate trenches has become a key measure to meet this demand, ensuring the safety and stability of the power system and improving grid security and power supply reliability. Under complex layout conditions, the crossing of different types of cable trenches is unavoidable. Generally, buried pipes or fireproof partitions are used at the crossing points, but because the cables are concentrated at the crossing points, heat dissipation is poor, posing a fire safety hazard to the substation. Furthermore, these methods encroach on cable laying space in later renovation and expansion projects, involve a large workload, and have poor visual appeal, creating difficulties for cable laying and subsequent work.

[0003] To address this issue, a different type of cross-clamp cable trench box is proposed. Utility Model Content

[0005] The specific technical solution of this utility model is: a cross-type snap-fit ​​cable trench box of different types, including a cable trench and a cable trench box set at the intersection of the cable trenches. The bottom of the cable trench box is provided with multiple support members, and the four corners of the cable trench box are longitudinally provided with limiting angle steel to limit the overall position of the cable trench box.

[0006] The cable tray is composed of multiple snap-fit ​​trays stacked in a crisscross pattern. The middle of each snap-fit ​​tray is a cable culvert. The two outer side walls of each snap-fit ​​tray are respectively provided with snaps and slots that can engage. Adjacent snap-fit ​​trays on the left and right are connected by snaps and slots.

[0007] Furthermore, preferably, the snap-fit ​​trough is provided with several reinforcing partitions to divide the cable culvert into several channels.

[0008] Furthermore, preferably, the reinforcing partition is arranged longitudinally, laterally, or in a crisscross pattern.

[0009] Furthermore, preferably, both the snap-fit ​​slot box and the reinforcing partition are made of fire-resistant materials or galvanized sheets coated with fire-retardant paint.

[0010] Furthermore, preferably, the support member separates the bottom of the cable tray from the bottom surface of the cable trench, so that there is a gap between the bottom of the cable tray and the bottom surface of the cable trench.

[0011] Furthermore, preferably, the gap between the support and the bottom surface of the cable trench is filled with a layer of crushed stone.

[0012] Furthermore, preferably, the crushed stone layer is surrounded by a stainless steel filter screen for fixation.

[0013] The present invention has the following beneficial effects: The snap-fit ​​cable tray designed in this invention can be freely assembled to adapt to cable laying at the intersection of different types of cable trenches, providing a solution for cable laying at the intersection of different types of cable trenches.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 Figure 2 As shown in the figure, this embodiment provides a different type of cable trench cross-clamping trough box, including a cable trench 1 and a cable trough box 2 set at the intersection of the cable trench 1. The bottom of the cable trough box 2 is provided with multiple support members 3, which are fixed to the bottom surface of the cable trench 1 by bolts. Limiting angle steel 4 is set longitudinally at the four corners of the cable trough box 2 to limit the overall position of the cable trough box 2 and prevent the cable trough box 2 from shifting during cable laying.

[0024] like Figures 3 to 5 As shown, the cable tray 2 is composed of multiple snap-fit ​​trays 5 stacked in a crisscross pattern. The central part of each snap-fit ​​tray 5 is a cable culvert 51 for laying cables. The two outer side walls of each snap-fit ​​tray 5 are respectively provided with snaps 52 and slots 53 that can engage. Adjacent snap-fit ​​trays 5 on the left and right sides are connected by snaps 52 and slots 53. The top and bottom surfaces of each snap-fit ​​tray 5 are provided with matching protruding limiting blocks 54 and concave limiting grooves 55. Adjacent snap-fit ​​trays 5 on the top and bottom are matched and locked by the protruding limiting blocks 54 and concave limiting grooves 55. It should be noted that the cable tray 2 can be configured with appropriate sizes and quantities of snap-fit ​​trays 5 according to the width and depth of different types of cable trenches, as well as the type, model, and quantity of cables to be separated. These can be assembled to obtain a suitable overall cable tray 2 to meet the cable separation and laying requirements at the intersections of cable trenches 1.

[0025] like Figure 3 The cable tray 2 shown is arranged in four layers, with two snap-fit ​​trays 5 in each layer. The snap-fit ​​trays 5 in each layer are connected as one unit by snap-fit ​​52 and snap-fit ​​groove 53 on the side wall. The snap-fit ​​trays 5 between adjacent layers are matched and snapped together by the outer protruding limiting block 54 and inner concave limiting groove 55 at the bottom of the upper layer and the inner concave limiting groove 55 and outer protruding limiting block 54 at the bottom of the lower layer. The adjacent layers are arranged in a cross pattern.

[0026] In a preferred embodiment of this invention, the snap-fit ​​cable tray 5 is provided with several reinforcing partition plates 56. On the one hand, this increases the structural strength of the snap-fit ​​cable tray 5, making it sufficient to withstand the weight of the laid cables; on the other hand, it divides the cable culvert 51 into several channels, meeting the construction requirements for further separated cable laying. Moreover, depending on specific usage needs, the reinforcing partition plates 56 can be arranged horizontally or in a crisscross pattern, in addition to the longitudinal arrangement as in this embodiment.

[0027] As a preferred embodiment of this example, both the snap-fit ​​slot box 5 and the reinforcing partition plate 56 are made of fireproof materials or galvanized plates coated with fireproof paint to meet fire protection requirements.

[0028] In a preferred embodiment of this invention, the support member 3 separates the bottom of the cable tray 2 from the bottom surface of the cable trench 1, creating a gap between the bottom of the cable tray 2 and the bottom surface of the cable trench 1. This gap ensures proper drainage of the cable trench and prevents water accumulation.

[0029] Furthermore, the gap between the support member 3 and the bottom surface of the cable trench 1 is filled with a layer of crushed stone 6, and a stainless steel filter screen 7 is fixed around the crushed stone layer 6. The crushed stone layer 6 and the stainless steel filter screen 7 can make the cable trough 2 stably supported and ensure smooth drainage.

[0030] In use, select the appropriate size and quantity of snap-fit ​​cable trays 5 according to the length, width, and height of the structure at the intersection of cable trench 1, as well as the type, model, and quantity of the separated cables. Assemble all snap-fit ​​cable trays 5 into a single cable tray 2 by connecting them horizontally and vertically, and install support members 3 at the bottom of the cable tray 2. Place the assembled cable tray 2 at the intersection of cable trench 1, connect and fix the support members 3 to the bottom surface of cable trench 1, then fill the gap between the cable tray 2 and the bottom surface of cable trench 2 with a layer of crushed stone 6, and fix a stainless steel filter screen 7 around the crushed stone layer 6 to ensure proper drainage at the intersection of cable trench 1. Then, fix limiting angle steel 4 longitudinally at the four corners of the cable tray 2 to limit and fix it. This completes the installation of the snap-fit ​​cable trays, and cables are laid through the cable culverts 51 of each snap-fit ​​cable tray 5.

[0031] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above.
