Description

Technical Field

[0001] This utility model belongs to the field of operating mechanism opening and closing technology, specifically relating to a device for visualizing the opening and closing position of an operating mechanism. Background Technology

[0002] In the operating mechanism of high-voltage switchgear, the open / close position indicator is a core component ensuring the safe operation of the power grid. Its function is to provide critical operational feedback to maintenance personnel by intuitively displaying the "closed" or "open" status of the switch. However, existing technical solutions have significant defects in transmission structure, space utilization, and functional integration, resulting in low equipment reliability and high maintenance costs, making it difficult to meet the needs of smart grids for efficient and visualized operation and maintenance.

[0003] Currently, traditional operating mechanism position indicators generally use bevel gear pairs to achieve vertical reversal of the movement direction, thereby displaying the open and closed status. However, this technology has significant bottlenecks. The bevel gear pairs require matching bearings, lubrication systems, and seals, resulting in redundancy in the transmission chain. Secondly, the bevel gear material must be high-strength alloy steel and undergo carburizing and quenching treatment. The cost of a single gear pair accounts for about 40% of the total indicator cost, and the requirements for machining accuracy are stringent. Although the traditional four-bar linkage can achieve the conversion between linear and rotary motion, it requires a large swing space, which increases the overall size of the indicator. Utility Model Content

[0004] The purpose of this utility model is to provide a visual device for the opening and closing position of the operating mechanism, so as to solve the technical defects in the prior art, which are that the bevel gear pair requires matching bearings, lubrication system and seals, resulting in redundancy of the transmission chain, and the four-bar linkage, although it can realize the conversion between linear motion and rotational motion, requires a large swing space, resulting in an increase in the overall size of the indicator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for visualizing the opening and closing positions of an operating mechanism, characterized in that it comprises:

[0007] A support plate is provided with a counting component, an indicating component and a driving component. The counting component and the indicating component are located at one end of the support plate, and the driving component is located at the other end of the support plate, with the driving component being axially perpendicular to the indicating component.

[0008] The ends of both the counting component and the driving component are connected to the bottom of the indicating component; wherein, when the driving component drives the indicating component to rotate to display the open / close position, the counting component records the number of times the indicating component rotates.

[0009] Furthermore, the counting component includes a bent plate, which is fixedly connected to a support plate. A counting unit is provided on the top of the bent plate, and the end of the counting unit is connected to the bottom of the indicating component through an elastic unit.

[0010] The drive assembly includes an output shaft mounted on a support plate. One end of the output shaft is connected to an external operating mechanism, and an adjusting rod is screwed onto the other end. The end of the adjusting rod is connected to the bottom of the indicating assembly via a telescopic assembly.

[0011] When the drive component rotates clockwise, the adjusting rod drives the telescopic component to push the indicator component to rotate and display the opening and closing position. Simultaneously, the indicator component drives the counting unit to work through the elastic unit.

[0012] Furthermore, a rotating plate is connected to the end of the counting unit, and one end of the elastic unit is connected to the rotating plate;

[0013] The telescopic component includes two spherical bearings connected by a double-ended screw. The spherical bearing closer to the counting unit is connected to the adjusting rod, while the spherical bearing farther from the counting unit is connected to the indicating component.

[0014] Furthermore, the indicating component includes a connecting plate, one end of which is connected to the other end of the elastic unit, and the other end is connected to a connecting shaft, with an indicator mounted on the top of the connecting shaft;

[0015] A bushing is provided on the outside of the connecting shaft, and the bushing is installed in the fixing block.

[0016] Furthermore, a limit block is screwed onto the outer side of the adjusting rod, and the limit block abuts against the outer side of the output shaft.

[0017] Furthermore, the counting unit is a counter.

[0018] Furthermore, the elastic unit is a spring.

[0019] Furthermore, the bent plate has an L-shaped structure.

[0020] Furthermore, the indicator is equipped with a position status display component.

[0021] Furthermore, the position status display component includes an open status display unit and a closed status display unit, both of which are engraved on the outside of the indicator.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The support plate serves as the basic structure, integrating the counting component, indicating component, and drive component together. This results in a compact overall device structure, facilitating installation and maintenance while reducing costs. The counting component records the number of rotations of the indicating component, providing quantitative data for the opening and closing operations of the operating mechanism. This helps monitor and evaluate the operating status and service life of the operating mechanism. Simultaneously, the indicating component displays the opening and closing position through rotation, simplifying the transmission process, improving transmission efficiency, and allowing operators to intuitively understand the current status of the operating mechanism, thus enhancing operational safety and convenience. Finally, the drive component, as the power source, drives the indicating component to rotate, achieving automatic indication of the opening and closing position and enhancing the automation and flexibility of the device.

[0024] 2. The end of the counting unit is connected to the bottom of the indicating component through an elastic unit, which not only ensures a reliable connection between the counting unit and the indicating component, but also allows for a certain degree of elastic deformation. This helps to absorb and buffer the impact force generated when the indicating component rotates, protecting the counting unit from damage. When the indicating component rotates, the counting unit is driven by the elastic unit, which enables accurate recording of the number of rotations of the indicating component, providing reliable data support for the monitoring and maintenance of the operating mechanism.

[0025] 3. The double-ended screw connects two spherical bearings, which not only ensures the structural stability of the telescopic assembly but also enables precise transmission. By adjusting the length of the double-ended screw, the overall length of the telescopic assembly can be finely adjusted, thereby precisely controlling the rotation angle and position of the indicator assembly and improving the accuracy of the opening and closing position indication.

[0026] 4. An indicator is installed on the top of the connecting shaft so that the indicator can rotate with the rotation of the connecting shaft, thereby intuitively displaying the open and closed position of the operating mechanism. This allows operators to quickly and accurately understand the status of the operating mechanism, improving the safety and efficiency of operation.

[0027] 5. The limiting block screwed to the outside of the adjusting rod can be rotated to adjust the position of the limiting block on the adjusting rod, thereby achieving precise limitation on the movement range of the adjusting rod. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] This embodiment provides a visualization device for the opening and closing position of an operating mechanism. The following is a further detailed description of this utility model with reference to the accompanying drawings:

[0039] like Figures 1-3 As shown, a visual device for the opening and closing position of an operating mechanism includes a support plate 1, on which a counting component, an indicating component, and a driving component are provided. The counting component and the indicating component are located at one end of the support plate 1, and the driving component is located at the other end of the support plate 1, with the driving component being axially perpendicular to the indicating component.

[0040] Both the counting component and the drive component are connected to the bottom of the indicating component; when the drive component drives the indicating component to rotate to display the opening and closing position, the counting component records the number of times the indicating component rotates.

[0041] In the above structure, the support plate 1 serves as the basic structure, integrating the counting component, indicating component, and drive component together, making the entire device compact and easy to install and maintain. The counting component and indicating component are located at one end of the support plate 1, and the drive component is located at the other end, with the drive component axially perpendicular to the indicating component. This optimizes space utilization, avoids mutual interference between components, and reduces the size of the indicating component. During application, one end of the drive component is connected to the operating mechanism, and the other end serves as a power source to drive the indicating component to rotate. The counting component is responsible for recording the number of rotations of the indicating component, realizing automatic indication of the opening and closing position, enhancing the automation and flexibility of the device, providing quantitative data for the opening and closing operation of the operating mechanism, and helping to monitor and evaluate the working status and service life of the operating mechanism. The indicating component displays the opening and closing position by rotating, allowing operators to intuitively understand the current status of the operating mechanism, improving the safety and convenience of operation.

[0042] Furthermore, the counting component includes a bent plate 2, which has an L-shaped structure and is fixedly connected to the support plate 1. A counting unit 3 is located on the top of the bent plate 2, and the end of the counting unit 3 is connected to the bottom of the indicating component via an elastic unit 4. The drive component includes an output shaft 13, which is mounted on the support plate 1. One end of the output shaft 13 is connected to an external operating mechanism, and the other end is screwed with an adjusting rod 12. The end of the adjusting rod 12 is connected to the bottom of the indicating component via a telescopic component, and a limit block is screwed to the outer side of the adjusting rod 12, abutting against the outer side of the output shaft 13. When the drive component rotates clockwise, the adjusting rod 12 drives the telescopic component to push the indicating component to rotate and display the opening / closing position. Simultaneously, the indicating component drives the counting unit 3 to operate via the elastic unit 4. The fixed connection between the bent plate 2 and the support plate 1 provides stable support for the counting unit 3, ensuring that the counting unit 3 will not shift or be damaged due to vibration or external force during operation. The end of the counting unit 3 is connected to the bottom of the indicating component via an elastic unit 4. This ensures a reliable connection between the counting unit 3 and the indicating component while allowing for a certain degree of elastic deformation, which helps absorb and buffer the impact force generated when the indicating component rotates, protecting the counting unit 3 from damage. When the indicating component rotates, the elastic unit 4 drives the counting unit 3 to operate, achieving accurate recording of the number of rotations of the indicating component and providing reliable data support for the monitoring and maintenance of the operating mechanism. The output shaft 13 is mounted on the support plate 1 and connected to the external operating mechanism, allowing the drive component to easily receive external power and transmit it to the indicating component to indicate the opening and closing positions. The other end of the output shaft 13 is screwed with an adjusting rod 12. By rotating the adjusting rod 12, its position can be adjusted, thereby adjusting the pushing force and angle of the telescopic component on the indicating component, improving the adaptability and flexibility of the device. When the drive component rotates clockwise, the adjusting rod 12 drives the telescopic component to push the indicating component to rotate and display the opening and closing positions. At the same time, the indicating component synchronously drives the counting unit 3 to operate via the elastic unit 4, achieving synchronous operation of the opening and closing position indication and counting functions, improving the working efficiency of the device.

[0043] Specifically, the counting unit 3 is a counter, and a rotating plate is connected to one end of the counting unit 3. One end of the elastic unit 4 is connected to the rotating plate. The telescopic component includes two spherical bearings 10, which are connected by a double-ended screw 11. The spherical bearing 10 closer to the counting unit 3 is connected to the adjusting rod 12, and the spherical bearing 10 farther from the counting unit 3 is connected to the indicating component. In the above structure, the rotating plate connected to the end of the counting unit 3 and the elastic unit 4 connected to the rotating plate allow for a certain relative movement space between the counting unit 3 and the elastic unit 4, enhancing the flexibility of the connection and enabling it to adapt to the dynamic changes generated when the indicating component rotates. This reduces stress concentration and component damage that may be caused by rigid connection. At the same time, the presence of the rotating plate can disperse and buffer the force transmitted from the rotating indicating component, preventing the force from acting directly on the counting unit 3, thereby protecting the counting unit 3 from excessive impact and extending its service life.

[0044] The telescopic assembly employs a structure where two spherical bearings 10 are connected by a double-ended screw 11. The spherical bearings 10 have multi-directional rotation and adjustment functions, allowing the entire telescopic assembly to be flexibly adjusted in multiple directions to adapt to transmission requirements at different angles and in different directions. The double-ended screw 11 connects the two spherical bearings 10, ensuring both structural stability and precise transmission. By adjusting the length of the double-ended screw 11, the overall length of the telescopic assembly can be fine-tuned, thereby precisely controlling the rotation angle and position of the indicator assembly and improving the accuracy of the opening and closing position indication.

[0045] In this embodiment, the indicating component includes a connecting plate 6, one end of which is connected to the other end of the elastic unit 4, and the other end is connected to the connecting shaft 8. An indicator 9 is mounted on the top of the connecting shaft 8. A bushing 7 is provided on the outer side of the connecting shaft 8, and the bushing 7 is installed in the fixing block 5. The connection of one end of the connecting plate 6 to the elastic unit 4 and the other end to the connecting shaft 8 can stably transmit the power from the drive component to the connecting shaft 8, ensuring that the indicating component can accurately respond to the action of the drive component and realize reliable indication of the opening and closing position.

[0046] The elastic unit 4 is a spring, and the connecting plate 6 is an intermediate connecting part, which simplifies the connection structure between the elastic unit 4 and the connecting shaft 8, reduces unnecessary parts, reduces the complexity and cost of the device, and also improves the reliability and maintainability of the device.

[0047] An indicator 9 is installed on the top of the connecting shaft 8, so that the indicator 9 can rotate with the rotation of the connecting shaft 8, thereby intuitively displaying the opening and closing position of the operating mechanism, making it easy for operators to quickly and accurately understand the status of the operating mechanism, and improving the safety and efficiency of operation.

[0048] A bushing 7 is provided on the outer side of the connecting shaft 8. The bushing 7 is installed in the fixing block 5, providing stable support and guidance for the connecting shaft 8. The bushing 7 can reduce friction and wear of the connecting shaft 8 during rotation, extend the service life of the connecting shaft 8, and ensure that the connecting shaft 8 can rotate smoothly and accurately. The fixing block 5 fixes the bushing 7 to the bearing plate 1, so that the entire indicating assembly can be stably installed in the device, which is not easy to shake or shift, improving the overall stability and reliability of the device and ensuring the accuracy of the opening and closing position indication.

[0049] In this embodiment, the indicator 9 is provided with a position status display component, which includes an open status display unit and a closed status display unit. Both the open status display unit and the closed status display unit are engraved on the outside of the indicator 9. The open status display unit is marked with the word "open", and the closed status display unit is marked with the word "close".

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
