Description

Technical Field

[0001] This utility model relates to the field of cable platform technology, specifically to an independent cable platform. Background Technology

[0002] In power transmission networks, when transmission lines enter cities, cross special terrains, or areas that need to be coordinated with the environment, it is often necessary to convert the overhead conductors on the power towers into buried insulated underground cables. This conversion process requires the connection and insulation of the conductors through cable terminals, and is equipped with protective equipment such as surge arresters. In order to centrally install, support, and maintain these large pieces of equipment, a dedicated cable platform must be set up at the conversion point.

[0003] Currently, most common cable platforms are steel structures. During the erection of the power tower, the cable platform needs to be fixed to the tower, usually welded or bolted directly to the main structure of the transmission tower, forming an integrated structure. The top of the cable platform is covered with steel plates or a grating floor to provide a working surface for workers. However, because the cable platform is pre-fixed to the tower, its position and dimensions are determined before installation, which limits its versatility and flexibility. If the height or position of the cable platform changes, the entire tower and cable platform assembly needs to be redesigned and reinstalled, which not only increases costs but also reduces project efficiency.

[0004] Secondly, and more inconveniently, during the installation of the platform floor, the finished floor needs to be measured and cut on-site according to the specific installation locations of equipment such as cable terminals and surge arresters to make room for the equipment installation. This method is not only cumbersome and inefficient, but the cutting operation also damages the anti-corrosion layer of the material, affecting its service life, and also causes waste of materials.

[0005] Furthermore, running the cable down along the main structure of the power tower can cause the cable to bend during the process, which can easily lead to insufficient bending radius, damage to the insulation layer, and cause safety and quality accidents. Utility Model Content

[0006] The present invention aims to provide an independent cable platform, which adopts a modular and adaptable design to improve the flexibility and efficiency of cable platform installation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An independent cable platform includes a platform structure and multiple columns fixed to the bottom of the platform structure. The top of the platform structure is equipped with a row of cable terminals and a row of surge arresters. The platform structure includes multiple angle steels and multiple floor plates. The angle steels are crisscrossed and fixed to form a grid-like frame. The floor plates are arranged and fixed on the top of the grid-like frame. The platform structure is equipped with cable terminal mounting seats and surge arrester mounting seats. There are mounting holes for cable terminal mounting seats and surge arrester mounting seats between each floor plate. The top of the platform structure is equipped with a guardrail along the circumference. The side of the platform structure is also equipped with a ladder leading to the ground.

[0008] The principle and advantages of this scheme are: 1. This independent cable platform is set up next to the power tower. In some areas that cross highways, railways, etc., where it is not possible to lay overhead cables and underground cables are required, the overhead conductors on the power tower are converted into underground cables. The cable platform is used to house equipment such as surge arresters, cable terminals, and grounding boxes. It is suitable for situations where the power tower itself does not have a cable platform and a cable platform needs to be installed later or the platform needs to be modified to be buried underground.

[0009] 2. The number of independent cable platforms can be flexibly configured according to the number of circuits in the power tower, generally ranging from 1 to 4. The number of cable terminals and surge arresters can also be flexibly configured according to the number of cables in a single circuit. This modular design allows it to be widely used in transmission lines of different scales and has strong versatility.

[0010] 3. A modular installation mode is adopted. The platform structure consists of a grid frame formed by multiple angle steels and multiple floor panels of various specifications. The floor panels can be flexibly arranged according to the number and location of cable terminals and surge arresters, precisely clearing installation positions. For example, when there are 3 cables in each circuit, the floor arrangement needs to clear 3 cable terminal installation positions and 3 surge arrester installation positions. Adjustments can be made on-site as needed, making the installation process more flexible and convenient, improving installation efficiency, and reducing the workload of cutting or modifying the floor panels on-site, significantly shortening the construction cycle.

[0011] 4. The top of the platform structure is equipped with a guardrail along the circumference, which effectively prevents workers from falling while working on the cable platform, providing good safety protection for workers and reducing work risks; at the same time, there is a ladder leading to the ground on the side, and the guardrail has an opening at the connection between the ladder and the platform structure, which facilitates workers to go up and down the cable platform to carry out operation and maintenance work, thus improving work efficiency.

[0012] 5. This solution makes extensive use of common materials and structures such as angle steel, flooring, and standard parts (such as clamps), which are relatively simple to manufacture and do not require separate molds, thus reducing processing and construction costs.

[0013] Preferably, as an improvement, the cable terminal mounting base includes a lower cable terminal mounting plate, a plurality of cable terminal support rods, and an upper cable terminal mounting plate, which are fixedly connected from bottom to top. The lower cable terminal mounting plate and the upper cable terminal mounting plate are coaxially provided with cable terminal mounting holes.

[0014] Technical benefits: This solution uses the above-mentioned setup to raise the cable terminal so that the bottom of the cable terminal is higher than the cable platform, making it easier for workers to connect the insulated cable to the lower end of the cable terminal on the platform structure without having to go under the platform structure to perform wiring operations.

[0015] Preferably, as an improvement, the surge arrester mounting base includes a lower surge arrester mounting plate, a plurality of surge arrester support rods, and an upper surge arrester mounting plate, which are fixedly connected from bottom to top, and the upper surge arrester mounting plate is provided with mounting holes.

[0016] Technical effect: The above-mentioned configuration of this solution adopts a multi-layer support structure to provide circumferential support for the upper part of the surge arrester, ensuring that the surge arrester can be installed firmly and upright, avoiding the impact on its electrical performance or mechanical damage caused by shaking.

[0017] Preferably, as an improvement, the guardrail has an opening at the connection between the ladder and the platform structure.

[0018] Technical effect: The above-mentioned setup ensures that workers can safely and smoothly enter the work area when climbing the ladder to the cable platform without having to climb over the guardrail, thus eliminating a potential safety risk.

[0019] Preferably, as an improvement, the column is provided with a cable fixing device, which includes a plurality of cable fixing parts spaced apart from top to bottom. Each cable fixing part includes a connector, a support arm and a clamp. The connector is fixedly connected to the column, one end of the support arm is connected to the connector, and the clamp is fixed to the other end of the support arm.

[0020] Technical effect: The above-mentioned setup in this solution uses multiple spaced cable fixing components to force the cable to maintain a vertical downward posture, preventing the cable from bending excessively due to its own weight or wind swaying, protecting the cable insulation layer, and meeting the specifications for cable laying.

[0021] Preferably, as an improvement, the cable fixing assembly further includes a sleeve that is connected to the lowermost plurality of cable fixing members.

[0022] Technical benefits: The above-mentioned setup provides a robust mechanical protection layer for the part of the cable closest to the ground, preventing damage from external forces such as small animals gnawing, mechanical impacts, and accidental digging, thus significantly improving the operational safety of the cable in the underground section.

[0023] Preferably, as an improvement, the plurality of said floorboards include floorboards of various different sizes.

[0024] Technical benefits: The above-mentioned setup allows for flexible selection and installation based on the quantity and location of cable terminals and surge arresters, as well as the actual dimensions of the platform structure. This better adapts to different engineering needs. Furthermore, the reasonable arrangement of floor panels of different sizes allows for more precise clearing of installation positions for cable terminals and surge arresters, resulting in a more compact and rational spatial layout of the platform structure. This avoids wasting space and facilitates the installation and securing of cable terminals and surge arresters.

[0025] Preferably, as an improvement, multiple warning lights are fixedly provided on the side of the platform structure.

[0026] Technical effect: The above-mentioned settings can play a good warning role at night or in low visibility environments, alerting vehicles in the air and on the ground to avoid collisions and other accidents, and ensuring the safety of personnel and equipment around the cable platform.

[0027] Preferably, as an improvement, the number of cable terminals in a row is at least one, and the number of surge arresters in a row is also at least one.

[0028] Technical benefits: The above-mentioned setup of this solution is applicable to power systems of different sizes, whether small single-circuit systems or large-scale multi-circuit systems, and can meet the installation requirements of cable terminals and surge arresters, thus having a wide range of applications.

[0038] The following detailed description illustrates the specific implementation method: Example The basics are as follows: Figure 1-8 As shown: like Figure 1 As shown, independent cable platforms are installed next to overhead power tower 1 to convert overhead conductors into underground cables 5. The number of independent cable platforms matches the number of circuits in power tower 1, typically ranging from 1 to 4. Figure 1 The power tower 1 shown has two circuits, and two independent cable platforms are set up next to it. Each independent cable platform includes a platform structure 6 and multiple columns 7 fixed to the bottom of the platform structure 6. The bottom of each column 7 has a flange, which is fixed to the ground by ground bolts. A grounding box 4 for grounding is installed on each column 7. The top of the platform structure 6 has a row of cable terminals 2 and a row of surge arresters 3. The cable terminals 2 and surge arresters 3 are arranged side by side. There is at least one cable terminal 2 and at least one surge arrester 3 per row, depending on the number of cables 5 in each circuit. Each cable 5 is matched with one cable terminal 2 and one surge arrester 3. Figure 2 As shown in the figure, this embodiment illustrates the case where each loop includes 3 cables 5.

[0039] like Figure 6As shown, the platform structure 6 includes multiple angle steels 601 and multiple floor plates 602. The multiple angle steels 601 are fixed in a crisscross pattern to form a grid-like frame. The multiple floor plates 602 are arranged and fixed on top of the grid-like frame. The multiple floor plates 602 include floor plates of various sizes and specifications. The floor plates of various specifications are installed according to a specific number and position, which can just leave open the mounting holes of the cable terminal 2 and the surge arrester 3, so as to facilitate the fixing of the cable terminal mounting base 8 and the surge arrester mounting base 9 in the mounting holes. Moreover, the arrangement rule of the floor plates 602 can also be changed according to the number and position of the cable terminal 2 and the surge arrester 3, so that when the floor plates cover the grid-like frame formed by the angle steels 601, the mounting holes of the cable terminal 2 and the surge arrester 3 can be just left open.

[0040] like Figure 3-5 As shown, a guardrail 11 is provided around the top of the platform structure 6. The guardrail 11 can prevent workers from falling onto the platform structure 6, thus achieving a protective effect. A ladder 10 leading to the ground is also provided on the side of the platform structure 6, making it convenient for workers to climb onto the platform structure 6 for operation. The guardrail 11 has an opening at the connection between the ladder 10 and the platform structure 6, so that workers can easily enter the platform structure 6 after climbing to the top of the ladder 10 without being obstructed by the guardrail 11.

[0041] like Figure 7 As shown, the cable terminal mounting base 8 includes a lower cable terminal mounting plate 801, multiple cable terminal support rods 802, and an upper cable terminal mounting plate 803, which are fixedly connected from bottom to top. The cable terminal 2 is assembled to the first and last ends of the cable 5 to connect the overhead conductor of the power tower 1 to the underground insulated cable 5. Therefore, both the upper and lower ends of the cable terminal 2 are connected to the cable 5. Since the insulated cable 5 connected to the lower end of the cable terminal 2 needs to extend underground through the platform structure 6, the lower cable terminal mounting plate 801 and the upper cable terminal mounting plate 803 are coaxially provided with cable terminal mounting holes 804 to facilitate the installation of the insulated conductor at the bottom of the cable terminal 2. The cable terminal 2 is fixedly connected to the upper cable terminal mounting plate 803, raising the bottom of the cable terminal 2 to facilitate the connection of the insulated conductor to the lower end of the cable terminal 2.

[0042] like Figure 8 As shown, the surge arrester mounting base 9 includes a lower surge arrester mounting plate 901, multiple surge arrester support rods 902, and an upper surge arrester mounting plate 903, which are fixedly connected from bottom to top. The surge arrester 3 is connected between the overhead conductor and the ground and is connected in parallel with the cable 5 circuit. Therefore, the surge arrester 3 only needs to be electrically connected to the overhead conductor with a conductor at its top. This allows the surge arrester 3 to immediately activate and conduct the high-voltage surge current to the ground when a high voltage occurs, thereby limiting the voltage amplitude and protecting the cable. The bottom of the surge arrester 3 is fixedly connected to the lower surge arrester mounting plate 901. The upper surge arrester mounting plate 903 is provided with mounting holes to provide circumferential support for the upper part of the surge arrester 3 and improve the stability of the surge arrester 3 installation.

[0043] like Figure 4 As shown, a cable fixing device 12 is provided on the column 7. The cable fixing device 12 includes multiple cable 5 fixing parts arranged at intervals from top to bottom. Each cable 5 fixing part includes a connector 1201, a support arm 1202, and a clamp 1203. The connector 1201 is fixedly connected to the column. One end of the support arm 1202 is connected to the connector 1201, and the clamp 1203 is fixed to the other end of the support arm 1202. The insulated cable 5 extends downward from the bottom of the cable terminal 2, and the cable 5 cannot be bent. It is necessary to ensure that the cable 5 is perpendicular to the ground downward. Therefore, the clamp 1203 is used to fix the cable 5 to the support arm 1202. The multiple cable 5 fixing parts arranged from top to bottom ensure that the insulated cable 5 extends perpendicular to the ground downward. The cable 5 fixing assembly also includes a sleeve 13, which is connected to the multiple cable 5 fixing parts at the bottom, to achieve the protection effect of the cable 5 before the insulated cable 5 enters the ground.

[0044] like Figure 1 As shown, multiple warning lights 14 are fixedly installed on the side of the platform structure 6.
