Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a vibration-damping foundation for a substation. Background Technology

[0002] Vibration-resistant foundations for substations typically employ reinforced concrete foundations or foundations with vibration-damping layers to reduce the impact of vibrations generated during equipment operation on the surrounding environment and equipment. In existing technologies, a common method is to use a rubber pad layer to create an elastic buffer layer between the foundation and the ground to improve stability and extend the service life of the equipment. However, the service life of the rubber layer is closely related to the environment. In some areas, it is not convenient to use rubber as a foundation layer. The service life of rubber is greatly shortened in areas with high intensity such as sunlight and acid corrosion. Therefore, a vibration-resistant foundation for substations is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Substation vibration-damping foundations typically employ reinforced concrete foundations or foundations with vibration-damping layers to reduce the impact of vibrations generated during equipment operation on the surrounding environment and equipment. Existing technologies commonly use rubber pads to create an elastic buffer layer between the foundation and the ground to improve stability and extend equipment lifespan. However, the lifespan of rubber layers is highly dependent on environmental conditions; in some areas, rubber is not suitable as a foundation layer, and its lifespan is significantly shortened in environments with high levels of sunlight and acid corrosion. Therefore, this invention provides a vibration-damping foundation for substations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a vibration-damping foundation for a substation, comprising a base and a top plate, wherein multiple sets of vibration-damping mechanisms are provided between the base and the top plate, multiple sets of square grooves are provided parallel to the side of the base opposite to the top plate, and multiple sets of sliding plates are provided parallel to the side of the top plate opposite to the base, wherein the outer surface of the sliding plate is slidably fitted into the square groove to form a set of nested components, and a vibration-damping mechanism is provided between each set of nested components.

[0005] In a preferred embodiment, the vibration damping mechanism includes multiple fixed plates. A shaft is rotatably connected to both sides of each fixed plate. A stop block is fixedly connected to one end of each shaft. Two rotating plates are rotatably mounted on the outer surface of each shaft. A rotating hole is formed on one side of each rotating plate, and the inner wall of the rotating hole is rotatably connected to the outer surface of the shaft. A rotating hole is formed on one side of each rotating plate, and a rotating rod is rotatably connected to the inner wall of the rotating hole. A molded plate is fixedly connected between the two ends of the rotating rod. A telescopic rod is fixedly connected to one side of the molded plate, and a spring is provided on the outer surface of the telescopic rod. The top of the fixed plate is fixedly connected to the bottom of the top plate.

[0006] In a preferred embodiment, the vibration damping mechanism further includes multiple fixed shells, the inner wall of the fixed shells being slidably connected to the outer surface of the template, the inner wall of the template being fixedly connected to one end of the telescopic rod, and the bottom of the fixed shells being fixedly connected to the top of the base.

[0007] In a preferred embodiment, one end of the spring is fixedly connected to one side of the mold plate, and the other end of the spring is fixedly connected to the inner wall of the fixed shell.

[0008] In a preferred embodiment, the top of the top plate is provided with a sliding hole, and a limit plate is slidably connected to the inner wall of the sliding hole.

[0009] In a preferred embodiment, the bottom of the limiting plate is fixedly connected to the top of the base, and a support plate is fixedly connected to the top of the limiting plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By fixing multiple fixed plates along the center line of the top plate and by using shafts and rotating plates to balance each other, the structural stability of the top plate can be greatly increased. At the same time, by using springs to impart elastic potential energy, the elastic potential energy imparted by the springs will act on the rotating plates during the rotation of the plate. Thus, when vibration occurs, the springs act as a damping mechanism, greatly reducing the damage caused by vibration. The cooperation between the limiting plate and the sliding hole can ensure the stability of the top plate's movement trajectory and prevent the top plate from tilting. The cooperation between multiple square grooves and sliding plates can further prevent the top plate from tilting during movement, increasing the structural stability of the equipment. The telescopic rod can not only protect the springs from compression and bending, but also limit the plate, making the structure of the plate inside the fixed shell more stable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a vibration-damping foundation for a substation, comprising a base 1 and a top plate 5. Multiple sets of vibration-damping mechanisms 2 are provided between the base 1 and the top plate 5. Multiple sets of square grooves 3 are provided parallel to the side of the base 1 opposite to the top plate 5. Multiple sets of sliding plates 4 are provided parallel to the side of the top plate 5 opposite to the base 1. The outer surface of each sliding plate 4 is slidably fitted within the square grooves 3 to form a nested assembly. A vibration-damping mechanism 2 is provided between each nested assembly. The vibration-damping mechanism 2 includes multiple fixed plates 21, with both sides of the fixed plates 21 rotatably connected. A shaft 22 is connected to a stop block at one end. Two rotating plates 23 are rotatably mounted on the outer surface of the shaft 22. A rotating hole is opened on one side of the rotating plate 23. The inner wall of the rotating hole is rotatably connected to the outer surface of the shaft 22. A rotating hole is opened on one side of the rotating plate 23. A rotating rod is rotatably connected to the inner wall of the rotating hole. A mold plate 25 is fixedly connected between the two ends of the rotating rod. A telescopic rod 26 is fixedly connected to one side of the mold plate 25. A spring 27 is provided on the outer surface of the telescopic rod 26. The top of the fixed plate 21 is fixedly connected to the bottom of the top plate 5.

[0022] The vibration damping mechanism 2 also includes multiple fixed shells 24. The inner wall of the fixed shell 24 is slidably connected to the outer surface of the molded plate 25. The inner wall of the molded plate 25 is fixedly connected to one end of the telescopic rod 26. The bottom of the fixed shell 24 is fixedly connected to the top of the base 1.

[0023] One end of the spring 27 is fixedly connected to one side of the mold plate 25, and the other end of the spring 27 is fixedly connected to the inner wall of the fixed shell 24.

[0024] Through the above embodiments, multiple fixed plates 21 are fixed by the center line of the top plate 5, and the shaft 22 and the rotating plate 23 weigh each other, which can greatly increase the structural stability of the top plate 5. At the same time, the spring 27 imparts elastic potential energy. During the rotation of the rotating plate 23 by the mold plate 25, the elastic potential energy imparted by the spring 27 will act on the rotating plate 23. Thus, when vibration occurs, the spring 27 acts as a buffer for the vibration damping mechanism 2, which can greatly reduce the damage caused by vibration.

[0025] Furthermore, the telescopic rod 26 not only protects the spring 27 from being compressed and bent, but also limits the position of the mold plate 25, making the structure of the mold plate 25 inside the fixed shell 24 more stable.

[0026] A sliding hole 6 is provided at the top of the top plate 5, and a limit plate 7 is slidably connected to the inner wall of the sliding hole 6;

[0027] The bottom of the limiting plate 7 is fixedly connected to the top of the base 1, and the top of the limiting plate 7 is fixedly connected to the support plate 8;

[0028] Through the above embodiments, the cooperation between the limiting plate 7 and the sliding hole 6 can ensure the stability of the moving trajectory of the top plate 5 and prevent the top plate 5 from tilting.

[0029] Through the above embodiments, the cooperation of multiple square grooves 3 and sliding plates 4 can further prevent the top plate 5 from tilting during movement, thereby increasing the structural stability of the equipment.

[0030] Working principle:

[0031] like Figures 1-5 As shown, in use, multiple fixed plates 21 are fixed along the center line of the top plate 5, and the shaft 22 and the rotating plate 23 weigh each other, which greatly increases the structural stability of the top plate 5. At the same time, the spring 27 imparts elastic potential energy, and during the rotation of the rotating plate 23 by the mold plate 25, the elastic potential energy imparted by the spring 27 will act on the rotating plate 23. Thus, when vibration occurs, the spring 27 acts as a buffer for the vibration damping mechanism 2, which can greatly reduce the damage caused by vibration. The cooperation of multiple square grooves 3 and sliding plate 4, and the cooperation of limiting plate 7 and sliding hole 6, can ensure the stability of the moving trajectory of the top plate 5, prevent the top plate 5 from tilting, and thus increase the reset effect of the vibration damping mechanism 2.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
