Description

Technical Field

[0001] This utility model relates to the technical field of GIS busbar cylinders, and in particular to a protective structure for GIS busbar cylinders. Background Technology

[0002] GIS (Gas Insulated Switchgear) mainly consists of circuit breakers, disconnectors, grounding switches, instrument transformers, surge arresters, busbars, connectors, and outgoing terminals. It has advantages such as small footprint and fully enclosed components, making it unaffected by environmental interference. Therefore, with the rapid development of power grids and the increase in land costs, GIS equipment has been widely used. In high-altitude areas, due to extreme temperature differences between day and night, coupled with intense sunlight, GIS busbar cylinders are prone to cracking, causing gas leakage. Existing technologies address this problem by constructing GIS equipment inside buildings or building protective sheds. Existing technology publication number CN221709299U proposes a GIS busbar cylinder protection structure, including a support component, a fastening component, and a protection component. The fastening component is located at the upper end of the support component, with fastening frame screws connected to the upper surface of the connecting plate. The protection component is located inside the fastening component. However, height adjustment is relatively complex, and there is a certain distance between the through holes, making misalignment during GIS busbar cylinder installation easy, affecting its performance. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a GIS busbar protection structure that can be arbitrarily adjusted in height, is easy to install, increases the support area, and ensures stability.

[0004] This utility model discloses a GIS busbar protection structure, comprising a base, a support column, a height adjustment component, a support component, a protective component, and connecting components. The support column is installed at the top of the base, and the height adjustment component is installed inside the support column. The protective component is installed on the top of the height adjustment component via connecting components. The support component is installed on the outer wall of the base. The base is placed on the ground, and the support component allows adjustment of the support position according to the flatness of the ground, increasing the support area and ensuring stability. The GIS busbar is placed on the protective component, which is installed on the height adjustment component via connecting components. The height adjustment component allows for arbitrary height adjustment, facilitating the installation of the GIS busbar.

[0005] Preferably, the height adjustment assembly includes a lifting screw, a bevel gear, a drive shaft, a drive gear, a nut, a lifting column, and a support plate. The support column has a drive cavity at its bottom and a telescopic cavity at its top. The lifting screw is rotatably mounted within the telescopic cavity, with the bevel gear installed at its lower end extending into the drive cavity. The drive shaft is rotatably mounted on the side wall of the support column, with a drive gear installed at its left end, meshing with the bevel gear. A nut is installed at the other end of the drive shaft. The lifting column is located within the telescopic cavity and screwed onto the outer wall of the lifting screw. A support plate is installed at the top of the lifting column. Rotating the nut drives the drive gear via the drive shaft, which meshes with the bevel gear, causing the lifting screw to rotate and pushing the lifting column out of the telescopic cavity, thus adjusting the height of the support plate. This allows for arbitrary height adjustment, facilitating the installation of GIS busbars and improving practicality.

[0006] Preferably, it also includes multiple guide sliders, and multiple guide grooves are provided on the inner wall of the telescopic cavity. Multiple guide sliders are axially and evenly installed on the outer wall of the lower end of the lifting column. The guide sliders are slidably installed in the guide grooves. When the lifting column moves up and down, it drives the guide sliders to slide in the guide grooves to limit and guide them, ensuring stability.

[0007] Preferably, the protective assembly includes two mounting bases, two protective plates, multiple sets of springs, and two sets of fastening plates. The two mounting bases are located above the support plate, and the protective plates are mounted on the mounting bases. The fastening plates are connected to the inner walls of the protective plates by multiple springs. The protective plates are fitted onto the outer surface of the GIS busbar. The fastening plates on the inner side of the protective plates push the springs to perform elastic compression, thereby improving the fastening effect. When the GIS busbar cracks, the fastening plates will be stretched open, but due to the elastic force, the fastening plates will contract, thereby tightening the crack and closing it with elastic force, reducing the possibility of air leakage in the GIS busbar.

[0008] Preferably, the connecting component includes two arc-shaped insert plates, two sets of connecting plates, and two sets of studs. The top of the support plate has symmetrical insertion slots on the left and right sides. The bottom of the mounting base is connected to the arc-shaped insert plate. The front and rear ends of the arc-shaped insert plate are equipped with connecting plates. The two connecting plates are connected by studs. The arc-shaped insert plate and the connecting plate at the bottom of the mounting base are inserted into the insertion slots at the top of the support plate. The connecting plates are connected by studs, which makes it easy to fit the protective plate on the outside of the GIS busbar.

[0009] Preferably, the support assembly includes multiple support arms, multiple threaded sleeves, multiple threaded support rods, multiple drive nuts, and multiple rotating push seats. Multiple rotating grooves are formed on the outer wall of the base. The support arms are rotatably installed within these grooves. A rotating seat is rotatably mounted on the top of each threaded sleeve, and the rotating seat is mounted on the outer wall of the support column. The threaded support rods are screwed into the threaded sleeves, and the other end of each threaded support rod is rotatably connected to the top of the support arm via a rotating push seat. A drive nut is installed on the outer wall of the threaded sleeve. The multiple support arms increase the support area at the bottom of the base, ensuring stability. The drive nuts rotate the threaded sleeves, adjusting the extension length of the threaded support rods and the angle of the support arms, making it suitable for surfaces with varying flatness and improving practicality.

[0010] Preferably, it also includes vertical plates and multiple connecting screws. The vertical plates are installed on the top of the protective plates, and the two vertical plates are connected by multiple connecting screws. Tightening the connecting screws connects the two protective plates through the two vertical plates to ensure stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the base is placed on the ground, and the support position can be adjusted according to the flatness of the ground through the support component, which can increase the support area and ensure stability. The GIS busbar is placed on the protective component, and the protective component is installed on the height adjustment component through the connecting parts. The height can be adjusted arbitrarily through the height adjustment component, which is convenient for installing the GIS busbar. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5 As shown, a support column 2 is installed at the top of the base 1. A drive cavity is opened at the bottom of the support column 2, and a telescopic cavity is opened at the top of the support column 2. A lifting screw 3 is rotatably installed in the telescopic cavity. A bevel gear 4 is installed at the lower end of the lifting screw 3, which extends into the drive cavity. A drive shaft 5 is rotatably installed on the side wall of the support column 2. A drive gear 6 is installed at the left end of the drive shaft 5, and the drive gear 6 meshes with the bevel gear 4. A nut 7 is installed at the other end of the drive shaft 5. A lifting column 8 is located in the telescopic cavity and is screwed onto the outer wall of the lifting screw 3. A support plate 9 is installed at the top of the lifting column 8. Multiple guide grooves are opened on the inner wall of the telescopic cavity. Multiple guide sliders 10 are axially and evenly installed on the outer wall of the lower end of the lifting column 8. The guide sliders 10 are slidably installed in the guide grooves. Two mounting seats 16 are located above the support plate 9. Mounting seats 16 are equipped with... There is a protective plate 17, and a fastening plate 19 is connected to the inner wall of the protective plate 17 by multiple springs 18. A vertical plate 20 is installed on the top of the protective plate 17, and two vertical plates 20 are connected by multiple connecting screws 21. The top of the support plate 9 has symmetrical insertion slots on the left and right. The bottom of the mounting base 16 is connected to an arc-shaped insert plate 22. The front and rear ends of the arc-shaped insert plate 22 are connected to connecting plates 23. Two connecting plates 23 are connected by studs 24. The outer wall of the base 1 has multiple rotating slots. The support arm 11 is rotatably installed in the rotating slot. The top of the threaded sleeve 12 is rotatably provided with a rotating seat. The rotating seat is installed on the outer wall of the support column 2. The threaded support rod 13 is screwed into the threaded sleeve 12. The other end of the threaded support rod 13 is rotatably connected to the top of the support arm 11 through a rotating push seat 15. The outer wall of the threaded sleeve 12 is equipped with a drive nut 14.

[0020] Multiple support arms 11 increase the support area at the bottom of the base 1, ensuring stability. The threaded sleeve 12 rotates via the drive nut 14, adjusting the extension length of the threaded support rod 13 and the angle of the support arms 11, making it suitable for ground with varying flatness and improving practicality. The protective plate 17 is fitted onto the outer surface of the GIS busbar drum. The fastening plate 19 on the inner side of the protective plate 17 pushes the spring 18 for elastic compression, improving the fastening effect. When the GIS busbar drum cracks, the fastening plate 19 will be stretched open, but due to elasticity, it will contract, tightening the crack and reducing air leakage in the GIS busbar drum. The mounting base 16 has an arc-shaped insert at the bottom. Plate 22 and connecting plate 23 are inserted into the insertion slot at the top of support plate 9. Connecting plate 23 is connected by stud 24, which facilitates the fitting of protective plate 17 onto the outside of GIS busbar. Tightening connecting screw 21 connects the two protective plates 17 through two vertical plates 20 to ensure stability. Rotating nut 7 drives drive gear 6 to rotate through drive shaft 5. Drive gear 6 meshes with bevel gear 4 to drive lifting screw 3 to rotate, pushing lifting column 8 to extend out of telescopic cavity. Adjusting the height of support plate 9 allows for arbitrary height adjustment, facilitating the installation of GIS busbar and improving practicality. When lifting column 8 moves up and down, it drives guide slider 10 to slide in guide groove for limiting and guiding, ensuring stability.

[0021] like Figures 1 to 5 As shown, this utility model discloses a GIS busbar protection structure. During operation, multiple support arms 11 increase the support area at the bottom of the base 1, ensuring stability. Depending on the flatness of the ground, the threaded sleeve 12 is rotated by the drive nut 14, adjusting the extension length of the threaded support rod 13 and the angle of the support arms 11. This structure is suitable for grounds with varying flatness. The protective plate 17 is fitted onto the outer surface of the GIS busbar. The fastening plate 19 on the inner side of the protective plate 17 pushes the spring 18 for elastic compression. The arc-shaped insert plate 22 and connecting plate 23 at the bottom of the mounting base 16 are inserted into the insertion slot at the top of the support plate 9. The structure is then secured by screws... The column 24 connects to the connecting plate 23. Tightening the connecting screw 21 connects the two protective plates 17 through the two vertical plates 20. When the GIS busbar cylinder cracks, the fastening plate 19 will be stretched open, but based on the elastic force, the fastening plate 19 will contract, thereby tightening the crack. This will cause the crack to be closed by the elastic force, reducing the air leakage of the GIS busbar cylinder. Rotating the nut 7 drives the drive gear 6 to rotate through the drive shaft 5. The drive gear 6 meshes with the bevel gear 4 to drive the lifting screw 3 to rotate, pushing the lifting column 8 to extend out of the telescopic cavity. The height of the support plate 9 can be adjusted arbitrarily, which is convenient for installing the GIS busbar cylinder.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
