Description

Technical Field

[0001] This utility model relates to the field of power fence technology, specifically a power fence for power isolation. Background Technology

[0002] Electric fences are facilities used to isolate high-voltage equipment areas and ensure the safety of personnel and equipment. They are mainly used in scenarios such as high-voltage equipment maintenance and power distribution work in power systems. Generally speaking, electric fences need to be set up around high-voltage equipment to prevent unauthorized personnel from accidentally entering the energized area or work site.

[0003] Currently, existing power fences for power isolation are all one-piece designs, with fixed horizontal beams and vertical bars. They are rectangular, requiring the high-voltage equipment to be enclosed in the center. However, due to the varying sizes of different high-voltage equipment models, power fences of different lengths and widths must be selected based on the equipment's dimensions. Traditional power fences are not suitable for all types of high-voltage equipment. If the fence size is mismatched with the equipment size, it may fail to provide effective isolation or become too large, occupying excessive space around the equipment. Therefore, we propose a new type of power fence for power isolation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electric fence for power isolation, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power fence for power isolation, comprising posts and beams. Four concave plates are fixedly installed on both adjacent sides of the posts. Pull pins are slidably installed inside both sides of the beam. A connecting plate is fixedly installed at one end of each pull pin. A spring is installed on the outer side of each pull pin. Sliding pins are fixedly installed on both sides of the connecting plate. Two through slots are formed inside both sides of the beam. A sliding groove is formed on the inner side of each concave plate. Several U-shaped grooves are formed inside the concave plate and below the sliding grooves. The sliding pins cooperate with the sliding grooves and U-shaped grooves.

[0006] Furthermore, several first vertical rails are fixedly installed in the middle of the two crossbeams.

[0007] Furthermore, several second vertical rails are fixedly installed in the middle of the two concave plates.

[0008] Furthermore, a base is fixedly installed at the bottom of the column.

[0009] Furthermore, a cover is fitted onto the outer side of the column, and the cover engages with the base.

[0010] Furthermore, the base has several mounting holes inside.

[0011] This utility model provides a power fence for power isolation, which has the following beneficial effects:

[0012] This power fence for electrical isolation, with its crossbeams, concave plates, pull pins, connecting plates, springs, sliding pins, sliding grooves, and U-shaped grooves, can accommodate high-voltage equipment of different sizes. When the high-voltage equipment is large and the fence width needs to be adjusted, two workers simultaneously pull up the pull pins at the top of the crossbeams, causing the connecting plates and sliding pins to move upwards. This allows the sliding pins to slide from the U-shaped grooves into the sliding grooves, releasing the concave plate's restriction. Then, the uprights on one side can be pushed to allow the concave plate to slide a certain length outside the crossbeams, thus adjusting the fence width. After adjustment, releasing the pull pins causes the springs to rebound, pushing the connecting plates and engaging the sliding pins into the U-shaped grooves to fix the concave plate. The fence width can then be adjusted. It is suitable for high-voltage equipment of different sizes, has high compatibility, and does not occupy excessive space after installation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 5This utility model provides a technical solution: a power fence for power isolation, comprising posts 1 and crossbeams 2. Four concave plates 4 are fixedly installed on both adjacent sides of the posts 1. Pull pins 5 are slidably installed inside both sides of the crossbeam 2. A connecting plate 6 is fixedly installed at one end of each pull pin 5. A spring 7 is installed on the outside of each pull pin 5. Sliding pins 8 are fixedly installed on both sides of the connecting plate 6. Two through slots 9 are opened inside both sides of the crossbeam 2. A sliding groove 10 is opened on the inner side of each concave plate 4. Several U-shaped grooves 11 are opened inside the concave plate 4 and below the sliding grooves 10. The sliding pins 8 cooperate with the sliding grooves 10 and U-shaped grooves 11. The beam 2 is slidably connected to the concave plate 4. The inner side of the concave plate 4 is provided with a side groove that cooperates with the beam 2. When the high-voltage equipment is large and the width or length of the fence needs to be adjusted, the width and length of the fence can be adjusted to cooperate with high-voltage equipment of different sizes, thereby increasing the compatibility with high-voltage equipment of different sizes. When the high-voltage equipment is small, its space occupation can be reduced. When the high-voltage equipment is large, different widths can be adjusted to cooperate with it. It has high compatibility and is convenient and quick to adjust. One side of the slide groove 10 is directly opened to one end of the concave plate 4. The concave plate 4 can be removed from the beam 2, which makes it easy to assemble it around the high-voltage equipment.

[0021] Several first vertical rails 3 are fixedly installed in the middle of the two crossbeams 2; the first vertical rails 3 are fixedly installed in the middle of the two crossbeams 2 to serve as a barrier.

[0022] Several second vertical rails 12 are fixedly installed in the middle of the two concave plates 4. The second vertical rails 12 are fixedly installed in the middle of the two concave plates 4. After the overall width or length of the fence is adjusted, the concave plates 4 can slide a certain distance outside the crossbeam 2 to play a blocking role.

[0023] A base 13 is fixedly installed at the bottom of the post 1; the base 13 is used for the installation and fixation of the four corners of the fence.

[0024] A cover 14 is fitted onto the outer side of the column 1, and the cover 14 cooperates with the base 13. The cover 14 can protect the bolts or ground nails on the base 13 after the base 13 is fixed by bolts or ground nails.

[0025] The base 13 has several mounting holes 15 inside; by setting the mounting holes 15, the high-voltage equipment can be fixed by bolts or ground nails depending on whether the ground around it is cement or soil, thereby playing the role of fixing the fence.

[0026] In summary, this power fence for power isolation is used as follows: First, a post 1 is installed at one corner of the high-voltage equipment via the base 13. Then, the crossbeam 2 and the first vertical rail 3 are moved upward by pulling the pin 5 at the top of the crossbeam 2, causing the connecting plate 6 and the sliding pin 8 to move upward. This causes the connecting plate 6 to compress the spring 7, and simultaneously the connecting plate 6 causes the sliding pin 8 to slide upward in the through groove 9. Then, the crossbeam 2 can be inserted into the grooves inside the two concave plates 4 on one side of the post 1, and the sliding pin 8 slides into the sliding groove 10. After one crossbeam 2 has slid to a suitable distance inside the concave plate 4, the pin 5 is released, causing the spring 7 to rebound and push the connecting plate 6 and the sliding pin 8 back to their original positions. This allows the sliding pin 8 to engage in the U-shaped groove 11, thus fixing the crossbeam 2 inside the concave plate 4. Finally, by pulling the pin 5 on the other side of the top of the crossbeam 2, the sliding pin 8 is moved upward, and the other post 1 is connected to the crossbeam 2 via the concave plate 4. After assembly, the two assembled columns 1, the first vertical railing 3, and the concave plate 4 are used to surround the high-voltage equipment in the middle. Then, on the other side of the high-voltage equipment, the columns 1, the first vertical railing 3, and the concave plate 4 are assembled and connected by the crossbeam 2 to surround the high-voltage equipment in the middle. Finally, the width and length of the high-voltage equipment can be adjusted according to its volume. During adjustment, two workers pull the top pin 5 of the crossbeam 2 at the same time to move the connecting plate 6 and the sliding pin 8 upward, so that the sliding pin 8 slides from the U-shaped groove 11 into the sliding groove 10, thereby releasing the restriction on the concave plate 4. Then, the column 1 on one side can be pushed to make the concave plate 4 slide a certain length outside the crossbeam 2 to adjust the width of the fence. After the adjustment is completed, the pull pin 5 is released and the spring 7 rebounds to push the connecting plate 6 so that the sliding pin 8 is locked into the U-shaped groove 11 to fix the concave plate 4. Then the width of the fence can be adjusted.

[0027] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
