Description

Technical Field

[0001] This utility model belongs to the field of power transmission engineering technology, and in particular relates to a modular cable support structure for power transmission. Background Technology

[0002] In power transmission projects, to ensure the orderly laying and long-term stable operation of cables, cable supports are usually installed on the inner walls of underground trenches. These supports are structurally sound and fixed to the side walls or top of the trenches with anchors. They are arranged horizontally or in a stepped manner and can support multiple cables in layers. This facilitates the installation, maintenance, and ventilation of the cables, and effectively avoids mechanical damage and heat accumulation caused by the cables contacting the ground or overlapping, thereby ensuring the safe operation of the power system.

[0003] Currently, cable supports are generally independent unit-shaped support components, fixed to the inner wall of underground trenches via their vertical connections, and supported by horizontal supports. While this structure provides basic support, it has several shortcomings in practical applications. First, each support needs to be installed individually, resulting in a cumbersome installation process and low construction efficiency, especially noticeable in long-distance laying scenarios. Second, the supports rely on multi-point anchoring connections to the trench sidewalls, requiring numerous anchor points to be created in the trench's concrete structure during installation. This not only increases the workload but also easily damages the original trench structure, leading to a decrease in overall strength. Furthermore, the dense distribution of anchor points may cause stress concentration, posing a risk of concrete cracking or anchor loosening during long-term operation, further affecting the stability and safety of the supports. Third, because the supports are dispersed, their horizontal arrangement is difficult to uniformly adjust, resulting in irregular cable arrangement, which is detrimental to later maintenance and ventilation. In summary, the existing support structure has significant deficiencies in installation efficiency, structural integrity, operational safety, and cable management effectiveness, urgently requiring optimization and improvement. Utility Model Content

[0004] To address the problems of low efficiency of independent installation of existing cable supports, dense anchor points that damage the channel structure, poor support stability, and irregular cable layout, this utility model provides a modular cable support structure for power transmission.

[0005] This utility model is implemented as follows: a modular cable support structure for power transmission, characterized in that it includes a vertical support module and a horizontal support module. The upper part of the horizontal support module forms a cable support plane and its end is fixed to the vertical support module. The horizontal support module and the vertical support module form a single-layer overhead line unit. Several single-layer overhead line units are connected end to end through the vertical support modules to form the modular cable support structure for power transmission. At least the first and last vertical support modules in the modular cable support structure for power transmission are provided with anchor holes.

[0006] In the above technical solution, preferably, the vertical seat module is a vertical beam body composed of two side wing plates and a bottom plate. The two ends of the vertical seat module are provided with sleeves on the left and right sides, and adjacent vertical seat modules are connected by pins inserted into the sleeves.

[0007] In the above technical solution, preferably, a countersunk hole for inserting the pin is formed on the inner side of the sleeve, and the opening of the countersunk hole faces the outer side of the end of the vertical seat module.

[0008] In the above technical solution, preferably, the two ends of the pin form a conical structure.

[0009] In the above technical solution, preferably, the annular outer wall of the sleeve is welded to the inner wall of the side wing plate and the inner wall of the bottom plate of the vertical seat module, and two sleeves are symmetrically arranged on the inner side of the vertical seat module.

[0010] In the above technical solution, preferably, the anchor holes are respectively provided on the bottom plate of the sleeve near both ends.

[0011] In the above technical solution, preferably, the horizontal support module has a wedge-shaped structure, and the width of the end of the horizontal support module near the vertical seat module is greater than the other end. The end face of the end of the horizontal support module near the vertical seat module is in contact with the inner wall of the bottom plate of the vertical seat module. The end of the horizontal support module near the vertical seat module is connected to the side wing plate of the vertical seat module by bolts.

[0012] This modular cable support structure for power transmission adopts a single-layer overhead line unit composed of vertical support modules and horizontal support modules. Through the vertical assembly of multiple units, modular construction is achieved, which has the following advantages and effects:

[0013] First, the highly modular structure and standardized design of each cable-laying unit allow for flexible assembly and installation, facilitating rapid on-site construction and adjustments, and significantly improving installation efficiency. Second, only anchor holes at the beginning and end of the support frame are needed for overall fixation, reducing anchoring interference with the cable tray structure and avoiding weakening of the concrete structure due to extensive drilling, thereby improving the overall stability and durability of the cable tray. Third, the vertical support modules form a continuous support system through end-to-end connections, enhancing the overall stability and seismic performance of the support frame and reducing the risk of loosening and deformation during operation. In summary, this modular cable tray effectively solves the problems of low installation efficiency, dense anchoring, and structural instability associated with traditional supports.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] To address the problems of low efficiency in independent installation of existing cable supports, dense anchor points damaging the channel structure, poor support stability, and irregular cable layout, this utility model provides a modular cable support structure for power transmission. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0019] Please see Figures 1-3 A modular cable support structure for power transmission includes a vertical support module 1 and a horizontal support module 2.

[0020] The upper part of the horizontal support module forms a cable support plane, and its ends are fixed to the vertical support module. The horizontal support module is a component used to support cables, which are arranged horizontally to form a cable tray supported on the cable support plane of the horizontal support module. The horizontal support module is installed along the side wall of the channel at the same height, forming support for the cable tray.

[0021] The vertical support module is the basic component for installing the horizontal support module, and it is connected to the side wall of the channel and set in the vertical direction.

[0022] Horizontal support modules and vertical base modules form a single-layer cable-laying unit. Several single-layer cable-laying units are connected end-to-end through vertical base modules to form a modular cable support structure for power transmission. At least the first and last vertical base modules in the modular cable support structure for power transmission have anchor holes. The modular cable support structure for power transmission provides support for cables at different heights from top to bottom.

[0023] In this embodiment, specifically, the vertical support module is a vertical beam composed of two side wing plates 1-1 and a base plate 1-2, using metal channel steel profiles. Sleeves 3 are provided on the inner left and right sides of both ends of the vertical support module, and adjacent vertical support modules are connected by pins 4 inserted into the sleeves. Further, countersunk holes for pin insertion are formed on the inner side of the sleeves, with the openings facing the outer side of the end of the vertical support module and flush with the end of the module. The two ends of the pins form a tapered structure to facilitate insertion of the probe sleeves at both ends. The annular outer wall of the sleeve is welded to the inner wall of the side wing plates and the inner wall of the base plate of the vertical support module, and two sleeves are symmetrically arranged on the inner left and right sides of the vertical support module. The connection between adjacent vertical support modules is achieved through the insertion of pins into the sleeves.

[0024] Anchor holes are provided near both ends on the base plate of the sleeve. The anchor holes are through holes that penetrate the base plate of the sleeve.

[0025] The horizontal support module has a wedge-shaped structure, with the end of the horizontal support module closest to the vertical base module being wider than the other end. The end face of the horizontal support module closest to the vertical base module is flush with the inner wall of the base plate of the vertical base module. The end of the horizontal support module closest to the vertical base module is connected to the side wing plate of the vertical base module by bolts. The horizontal support module can be made of nylon, with a protrusion on the outer end to prevent the cable from slipping outwards. The inner end has a through hole for the bolt. With the inner end face of the horizontal support module against the inner side of the base plate of the vertical base module, the through hole at the end aligns with the bolt hole on the upper part of the vertical base module, and is fixed by a bolt and nut assembly that passes through both holes.

[0026] This structure allows for the selection of the number of single-layer overhead line units according to specific construction needs, thereby forming a support structure with the required number of layers. Furthermore, for fixing the device, the vertical base modules at both ends are anchored to the sidewalls of the construction channel to achieve the entire device's fixation, resulting in high construction efficiency.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
