Description

Technical Field

[0001] This utility model relates to the field of cable laying equipment technology, and in particular to a serpentine cable trough that is easy to lay. Background Technology

[0002] In power transmission systems, the laying of high-voltage cables is a crucial step. With increasing urban power load demand and higher voltage levels, cables are becoming an increasingly common choice for urban power supply lines. However, changes in cable load can cause conductor temperature rise, leading to thermal expansion and contraction of the cable itself. This thermal expansion effect is particularly pronounced when voltage levels, cable cross-sections, and line lengths increase, resulting in deformation and mechanical stress that severely damage cable accessories and ancillary facilities.

[0003] Currently, serpentine laying methods are commonly used to absorb the changes in cable thermal expansion and contraction and eliminate mechanical stress. However, traditional cable troughs have many problems when used for serpentine laying. The fixed structure of traditional cable troughs makes it difficult to flexibly adapt to the bending shape required for serpentine laying, resulting in installation difficulties and low construction efficiency; during the laying process, the cable is subjected to uneven stress, which can easily lead to damage due to excessive local stress. Utility Model Content

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a serpentine cable trough that is easy to lay, comprising a base plate, side plate a, and side plate b, wherein the base plate is semi-circular; both side plate a and side plate b are curved; side plate a and side plate b are respectively fixed to the base plate by perpendicular snap-fit; positioning holes B are provided at the curved parts of side plate a and side plate b; positioning holes A are provided on the base plate at positions opposite to positioning holes B; positioning pins are inserted through positioning holes A and positioning holes B to assemble and fix multiple sets of base plates, side plates a, and side plates b.

[0006] Furthermore, the bottom plate has a curved slot; both side plate a and side plate b have curved blocks at their bottoms; the blocks are inserted into and fixed to the slots.

[0007] Furthermore, an elastic buffer layer is provided on the inner side of the bend of side plate a; an elastic buffer layer is provided on the outer side of the bend of side plate b.

[0008] Furthermore, side plate a and side plate b are inserted and fixed to the base plate; the two ends of the positioning pin are respectively provided with external threads; the positioning pin passes through positioning hole A and positioning hole B in sequence, and is fixed by threaded connection between the positioning pin and the nut.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] This utility model features a curved base plate and side plates, facilitating serpentine cable laying, simplifying the installation process, and improving construction efficiency. The positioning holes and pins ensure the stability and uniform stress distribution of the cable trough, preventing cable damage. The slots in the base plate and the locking blocks in the side plates make assembly simple and quick. The elastic buffer layer of the side plates effectively absorbs external impacts, protecting the cables. Structural stability is further enhanced by the insertion and fixing of the side plates to the base plate, as well as the connection of nuts and positioning pins, ensuring long-term reliability.

[0017] The technical solution of this utility model embodiment will be clearly and completely described below with reference to the accompanying drawings: A serpentine cable trough that is easy to lay includes a base plate 1, side plate a2 and side plate b3. The base plate 1 is semi-circular. The side plates a2 and b3 are both curved, so that the cable trough can flexibly adapt to the bending shape required for serpentine laying, thereby simplifying the installation process and improving construction efficiency. The side plates a2 and b3 are respectively fixed to the base plate 1 by vertical snap-fit. The curved parts of the side plates a2 and b3 are provided with positioning holes B4. The base plate 1 is provided with positioning holes A102 at the opposite position to the positioning holes B4. Positioning pins 7 are inserted through the positioning holes A102 and B4 to assemble and fix multiple sets of base plates 1, side plates a2 and side plates b3. The positioning pins are used to fix the cable trough, ensuring the stability of the cable trough during installation and use, so that the cable is subjected to uniform force and avoiding cable damage caused by excessive local force.

[0018] Specifically, the base plate 1 has a curved slot 101 on its surface; the side plates a2 and b3 each have curved blocks 6 at their bottoms; the blocks 6 are inserted into and fixed to the slot 101. The base plate has a curved slot, and the side plates a and b each have curved blocks at their bottoms. The blocks are inserted into and fixed to the slots, making the assembly of the cable trough simple and quick.

[0019] An elastic buffer layer 5 is provided on the inner side of the bend of side plate a2; an elastic buffer layer 5 is provided on the outer side of the bend of side plate b3, which can effectively absorb and disperse external force impacts and protect the cable from damage.

[0020] The side plates a2 and b3 are inserted and fixed to the base plate 1; the two ends of the positioning pin 7 are respectively provided with external threads; the positioning pin 7 passes through the positioning hole A102 and the positioning hole B4 in sequence, and is fixed by the nut 8 to the positioning pin 7 through threaded connection, which further enhances the structural stability of the cable trough and ensures the reliability of long-term use.

[0021] When in use, after the construction personnel insert and fix the side plates a2 and b3 to the base plate 1, they place the bent cable clips into the cable trough. Since there are vertical laying situations in the serpentine laying, the base plate 1, side plate a2 and side plate b3 can be assembled upwards in sequence according to the number of cables to be laid. After placing multiple cables, the positioning pins 7 are inserted into the positioning holes A102 and B4 in sequence, and the nuts 8 are fixed at both ends respectively.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
