Description

Technical Field

[0001] The utility model belongs to the technical field of cable installation, and in particular relates to a connection component for an assembled cable trench. Background Art

[0002] Cable trenches are common structures used for laying cables and are essential infrastructure for substations, serving as a connecting link between various power distribution devices. Currently, cable trenches are primarily constructed using on-site bricklaying or poured concrete. This on-site approach requires waiting for the bricklaying or poured concrete to solidify, resulting in a long construction period, a cluttered environment, and increased costs.

[0003] The existing method of laying cable trenches is to prefabricate U-shaped cable trenches. Prefabricated U-shaped cable trenches can be produced on a large scale and in batches, saving materials and labor, and significantly reducing construction costs. At the same time, they can also reduce various constraints on on-site construction, improve installation efficiency, and speed up project progress. In the process of laying cables, due to the small number of cables at the end of the U-shaped cable trench, in order to dynamically adjust the trench depth and trench width of the U-shaped cable trench according to the number of local cables to achieve a "tailor-made" effect, the U-shaped cable trench generally has two different sizes of cable trenches: larger and smaller. However, when the cross-section of the U-shaped cable trench changes, it needs to be cast on-site, which brings inconvenience to the construction. In view of this, how to design a U-shaped cable trench with a variable cross-section to improve the degree of prefabrication is the technical problem to be solved by the present invention.

[0057] In one aspect, combined Figures 1 to 11 As shown, an embodiment of the present disclosure provides a connection component for an assembled cable trench. The connection component for the assembled cable trench includes a first connection member 1. The first connection member 1 is prefabricated and includes a first base plate 11 and a first side plate 12.

[0058] The first bottom plate 11 has a stepped structure. Two first side plates 12 are provided, and the two first side plates 12 are symmetrically arranged on both sides of the first bottom plate 11 . The two first side plates 12 are connected to the first bottom plate 11 and are located on the same side of the first bottom plate 11 .

[0059] The two first side plates 12 and the first bottom plate 11 are combined to form a first groove 13 . The first groove 13 also has a U-shaped structure. The first groove 13 is used for laying cables.

[0060] Combine Figure 2 As shown, along the installation direction of the cable, a first opening 14 and a second opening 15 are formed at both ends of the first groove 13 respectively, the groove width a1 of the first opening 14 is greater than the groove width a2 of the second opening 15, and the groove width a1 of the first opening 14 is equal to the groove width of the existing first cable trench 5, and the groove width a2 of the second opening 15 is equal to the groove width of the existing second cable trench 6, wherein the size of the first cable trench 5 is larger, and it is a larger U-shaped cable trench; the size of the second cable trench 6 is smaller, and it is a smaller U-shaped cable trench.

[0061] The width and depth of the first cable trench 5 are both greater than the width and depth of the second cable trench 6 .

This makes it easier for the two ends of the first connecting member 1 to be docked with the first cable trench 5 and the second cable trench 6, respectively, thereby realizing a variable cross-section of the U-shaped cable trench.

[0063] Specifically, by setting a first connecting member 1, the first connecting member 1 includes a first bottom plate 11 and a first side plate 12. The first bottom plate 11 has a stepped structure, and two first side plates 12 are provided.

The two first side plates 12 and the first bottom plate 11 enclose a first groove 13. A first opening 14 and a second opening 15 are formed at both ends of the first groove 13 respectively. The groove width of the first opening 14 is greater than the groove width of the second opening 15, and the groove depth of the first opening 14 is greater than the groove depth of the second opening 15. In this way, the first opening 14 of the first connecting member 1 can be connected to the existing first cable trench 5, and the second opening 15 can be connected to the existing second cable trench 6, thereby completing the variable cross-section conversion of the U-shaped cable trench. The first connecting member 1 improves the prefabrication degree of the cable trench under the variable cross-section condition, thereby improving installation efficiency and accelerating project progress, and greatly reducing construction costs.

[0064] Specifically, the first connector 1 is made of reinforced concrete, which has high strength and durability, can withstand the pressure of underground space, and can provide good support and protection. In addition, reinforced concrete has good fire resistance and can effectively protect the cable from the impact of fire.

[0065] In some embodiments of the present application, the first bottom plate 11 includes a first plate segment 111 , a second plate segment 112 and a third plate segment 113 .

[0066] The first plate segment 111 has a straight plate structure; the distance between the second plate segment 112 and the top of the first side plate 12 is smaller than the distance between the first plate segment 111 and the top of the first side plate 12, that is, the second plate segment 112 is located above the first plate segment 111; the width of the second plate segment 112 is smaller than the width of the first plate segment 111, the first opening 14 is located at the end of the first plate segment 111, and the second opening 15 is located at the end of the second plate segment 112, and the size of the first opening 14 is larger than the size of the second opening 15.
