DETAILED DESCRIPTION

[0054] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0055] like Figures 1-8 As shown, an embodiment of this utility model proposes a cable terminal pole platform, comprising:

[0056] Support steel frame 2 connected to terminal pole 1;

[0057] An insulating base plate laid on the supporting steel frame 2;

[0058] An insulated fence is distributed around the perimeter of the supporting steel frame 2.

[0059] In this embodiment, cable terminal pole platforms are set on both sides of the terminal pole 1. The connection between the supporting steel frame 2 and the terminal pole 1 provides a stable foundation support for the cable terminal pole platforms, ensuring the overall stability and safety of the equipment. This structure can effectively resist the influence of the external environment, thereby extending the service life of the equipment.

[0060] When a single-core cable passes through a closed loop, it generates electromagnetic current. The high conductivity of the cable terminal pole platform can cause the platform to generate heat and induce electricity, thereby affecting the cable insulation level and reducing the cable service life. In this application, by laying an insulating base plate on the supporting steel frame 2, the closed loop formed by the cable passing through the platform is effectively isolated, thereby greatly reducing the platform heating and extending the cable service life.

[0061] To prevent energized accidents caused by cable line faults, energized parts must maintain a certain safe distance from the fence. For 220kV and above cables and overhead lines, the existing cable terminal pole platform size is about 8-10m to meet the safety distance requirements. This utility model uses an insulating fence distributed around the perimeter of the supporting steel frame 2. Due to the good insulation performance of the insulating fence, the size of the cable terminal pole platform can be reduced by 1-2m, effectively reducing the cost while achieving the same effect. Furthermore, the insulating fence not only provides insulation but also serves as a safety protection measure, preventing maintenance personnel from accidentally coming into contact with cable terminal equipment or high-voltage lines during operation, thereby reducing the occurrence of safety accidents.

[0062] This utility model solves the problems of platform overheating and induced electricity affecting cable insulation levels by laying an insulating base plate on the supporting steel frame 2 and an insulating fence distributed along the perimeter of the supporting steel frame 2, while maintaining a safe distance.

[0063] In an optional embodiment of this utility model, the supporting steel frame 2 further includes:

[0064] The first end is fixedly connected to the connecting rod 11 on the terminal rod 1;

[0065] The bottom surface of the first channel steel 12 is fixedly connected to the top surface of the second end of the connecting rod 11;

[0066] The platform steel frame 13 is fixedly connected to the top surface of the first channel steel 12 at its bottom, and the insulating base plate is laid on the surface of the platform steel frame 13.

[0067] Multiple support columns 14 are connected to the bottom surface of the platform steel frame 13, and the bottom ends of the multiple support columns 14 are connected to the ground.

[0068] In this embodiment, the connecting rod 11 is erected at the bottom of the platform steel frame 13 via the first channel steel 12 and fixed by bolts, connecting to multiple support columns 14 on the bottom surface of the platform steel frame 13. The bottom ends of the multiple support columns 14 are connected to the ground. Erecting supports generally allows for more adjustment and adaptability, and can be adjusted according to different installation environments and conditions. Erecting supports can be quickly installed and disassembled, which is very useful in situations where frequent adjustments or maintenance are required. Erecting supports can reduce structural weaknesses, thereby improving the safety of the entire structure.

[0069] In an optional embodiment of this utility model, the platform steel frame 13 includes:

[0070] A U-shaped frame structure is formed by welding a first square steel 131, a second square steel 132, and a third square steel 133 end to end in sequence.

[0071] The included angle between the first square steel 131 and the second square steel 132 is equal to 90 degrees, and the included angle between the second square steel 132 and the third square steel 133 is equal to 90 degrees;

[0072] A fourth square steel 134 is welded to the second square steel 132. Multiple fourth square steels 134 are provided and are evenly distributed at a preset distance inside the U-shaped frame structure. The fourth square steels 134 closer to the first square steel 131 are spaced apart by a preset distance from the first square steel 131, and the fourth square steels 134 closer to the third square steel 133 are spaced apart by a preset distance from the third square steel 133.

[0075] In this embodiment, the lengths of the first square steel 131, the second square steel 132, and the third square steel 133 are equal, which is used to form the U-shaped frame structure into a square structure, which has many advantages. First, the square structure can make the internal space of the U-shaped frame structure highly symmetrical and balanced, and also makes the internal space of the U-shaped frame structure more effectively utilized.

[0076] The U-shaped frame structure of the square structure also has significant advantages in terms of stress, making the U-shaped frame structure have similar stiffness and strength in all directions, so that the U-shaped frame structure exhibits higher stability and load-bearing capacity when subjected to various loads; in addition, the diagonals of the U-shaped frame structure of the square structure are equal and perpendicular to each other, which makes the U-shaped frame structure maintain good stability when subjected to oblique loads.

[0077] The U-shaped frame structure of the square structure is relatively easy to construct, and it is easier to position and measure during construction, which reduces the difficulty and time of construction. In addition, the component dimensions of the U-shaped frame structure of the square structure are relatively uniform, which facilitates standardized production and processing, and improves construction efficiency and quality.

[0082] In this embodiment, two adjacent L-shaped angle steels 3 are symmetrically arranged to form a laying cavity, which restricts the laying direction of the insulating unit plate 4. The overall insulating base plate is decomposed into multiple strip plates, and the strip plates are further decomposed into multiple insulating unit plates 4. The side length of the insulating unit plate 4 is equal to the width of the laying cavity. The above-mentioned unitized laying method makes the insulating base plates densely laid and the structure stable. At the same time, decomposing the insulating base plate into smaller insulating unit plates 4 is convenient for manufacturing and maintenance and replacement.

[0083] In an optional embodiment of this utility model, the insulating unit plate 4 is a grid plate made of fiberglass.

[0084] In this embodiment, the insulating unit plate 4 is a grid plate made of fiberglass, which can effectively solve the problem of water accumulation in rainy and snowy weather.

[0090] Insulating plates 6 are installed between two adjacent insulating posts 5 by plugging them in, which facilitates the installation and removal of the insulating plates 6, thereby facilitating later maintenance and replacement. The insulating fence is formed by the detachable insulating posts 5 and insulating plates 6. The insulating posts 5 and insulating plates 6 are of uniform specifications, which is convenient for processing. At the same time, the plugging connection method can effectively improve construction efficiency.

[0091] In this embodiment, insertion cavities for inserting insulating strips 6 can be provided on both sides of the insulating post 5 to realize the insertion connection between the insulating post 5 and the insulating strips 6.
