Description

Technical Field

[0001] This application relates to the field of ring main units, and in particular to a primary and secondary integrated ring main unit isolation spring operating mechanism. Background Technology

[0002] The integrated primary and secondary ring main unit is a complete and collaborative intelligent power distribution unit that integrates primary equipment (such as switches and transformers) and secondary equipment (such as protection and control units and communication units) in a traditional ring main unit through standardized interfaces and modular design before leaving the factory.

[0003] The primary and secondary integrated ring main unit is equipped with a spring operating mechanism, which is a mechanical device that uses a spring to store and release energy to drive the switchgear to perform opening or closing operations. The existing primary and secondary integrated ring main unit's spring operating mechanism includes an isolation module and a grounding module. The isolation module and the grounding module are set independently, controlling the opening and closing of the isolation module and the grounding module respectively. This design occupies a large space. Utility Model Content

[0004] To reduce the space occupied, this application provides a primary and secondary fusion ring network box isolation spring operating mechanism.

[0005] This application provides a primary and secondary fusion ring network box isolation spring operating mechanism, which adopts the following technical solution: A primary and secondary fusion ring network box isolation spring operating mechanism includes a frame, an output shaft rotatably mounted on the frame, a rotating disk fixedly connected to the output shaft, an isolation drive module and a grounding drive module on the frame, the isolation drive module driving the rotating disk to rotate in the forward direction and the grounding drive module driving the rotating disk to rotate in the reverse direction, an energy storage module on the frame including an energy storage spring, the isolation drive module and the grounding drive module being located on opposite sides of the energy storage spring and both capable of compressing the energy storage spring, and an indicator module on the frame including an indicator plate rotatably mounted on the frame, the output shaft driving the indicator plate to rotate.

[0006] By adopting the above technical solution, the isolation drive module, grounding drive module, and energy storage module are integrated on the same frame and share the output shaft and rotating disk, realizing the integration of isolation and grounding operation mechanisms. The isolation drive module and the grounding drive module can control the forward and reverse rotation of the output shaft respectively, which significantly reduces the space occupied by the entire spring operating mechanism in the ring network box. At the same time, the energy storage spring provides power to the two operating modules, improving energy utilization efficiency and the structural compactness of the mechanism. The introduction of the indicator module can also reflect the operating status in real time, enhancing the monitorability and operational safety of the equipment.

[0007] Optionally, the isolation drive module includes an isolation operating shaft rotatably mounted on the frame and an isolation crank arm fixedly connected to the isolation operating shaft. An isolation transmission pin is eccentrically mounted on the isolation crank arm, and an oblong hole is provided on the rotating disk for the isolation transmission pin to be inserted and slid.

[0008] By adopting the above technical solution, the isolation drive module uses an eccentrically set isolation transmission pin that cooperates with the waist-shaped hole on the rotating disk, so that the rotational motion of the isolation operation shaft can be effectively converted into the rotation of the rotating disk, thereby realizing the isolation operation. This transmission method has a simple and reliable structure, occupies little space, and the design of the waist-shaped hole allows for a certain degree of freedom of movement, which is convenient for assembly and fine adjustment during the movement process, improving the adaptability and service life of the mechanism.

[0009] Optionally, a clearance hole is provided on the wall of the waist-shaped hole. When the grounding drive module drives the rotating disk to rotate in the opposite direction, the isolation transmission pin can slide from the waist-shaped hole into the clearance hole.

[0010] By adopting the above technical solution, a clearance hole is set on the wall of the oblong hole, so that when the output shaft of the isolation drive module rotates, the isolation transmission pin slides in the oblong hole. When the output shaft of the ground drive module rotates, the isolation transmission pin slides into the clearance hole. When the isolation drive module is not working, it will not interfere with the rotating disk. This achieves effective clearance during the operation of the ground drive module, which helps to prevent the mechanism from jamming, improves the smoothness of operation and the reliability of the mechanism, and simplifies the structural design and reduces the difficulty of manufacturing and assembly.

[0011] Optionally, the grounding drive module includes a grounding operating shaft rotatably mounted on the frame and a grounding crank arm fixedly connected to the grounding operating shaft. The grounding crank arm is eccentrically provided with a grounding transmission pin, and the rotating disk has a strip-shaped hole for the grounding transmission pin to be inserted and slid.

[0012] By adopting the above technical solution, the grounding drive pin in the grounding drive module cooperates with the strip hole on the rotating disk to realize the reverse drive function of grounding operation. The design of the strip hole allows the grounding drive pin to slide in it and push the rotating disk to rotate in the opposite direction, thereby completing the grounding opening and closing operation. This structure is not only compact, but also ensures the independence and coordination of grounding and isolation operations, and improves the functional integrity and operational accuracy of the entire mechanism.

[0013] Optionally, the strip hole penetrates the circumferential sidewall of the rotating disk, and a clearance arc surface is formed on the circumferential sidewall of the rotating disk. The grounding transmission pin can slide out of the strip hole. When the isolation drive module drives the rotating disk to rotate in the forward direction, the clearance arc surface is located outside the movement path of the grounding transmission pin relative to the rotating disk.

[0014] By adopting the above technical solution, the strip hole penetrates the circumferential sidewall of the rotating disk and is provided with a clearance arc surface. When the isolation drive module drives the output shaft to rotate, the grounding transmission pin can be located outside the strip hole, and interference with the grounding transmission pin is avoided when the rotating disk rotates. This avoids interference and wear of the grounding drive module in the non-operational state. The design of the clearance arc surface further optimizes the motion trajectory, reduces unnecessary friction and resistance, and helps to extend the service life of the mechanism and improve its motion accuracy.

[0015] Optionally, the frame includes a middle plate, on which a limiting hole extending around the central axis of the isolation operating shaft is provided. The isolation transmission pin slides within the limiting hole and can slide until it abuts against the wall of the limiting hole.

[0016] By adopting the above technical solution, a limiting hole is set on the middle plate of the frame to limit the movement range of the isolation transmission pin, which effectively prevents over-rotation or positional deviation during the isolation operation, improves the accuracy and safety of the operation, and the limiting hole has a simple structure and is easy to process. At the same time, it enhances the rigidity and stability of the entire mechanism and is suitable for high-frequency operating environments.

[0017] Optionally, the isolation drive module includes an isolation operating shaft rotatably mounted on a frame and an isolation limiting plate fixedly connected to the isolation operating shaft. The frame includes a front plate and a middle plate arranged along the axial direction of the isolation operating shaft. A limiting stud is provided between the front plate and the middle plate. The isolation operating shaft can rotate until the isolation limiting plate abuts against the limiting stud.

[0018] By adopting the above technical solution, the mechanical limiting of the isolation operating shaft is achieved by the contact between the isolation limiting plate and the limiting stud. This limiting method has a stable structure and is easy to adjust. It can effectively prevent damage to the mechanism or misoperation caused by excessive operation. The limiting stud is easy to disassemble and assemble. The arrangement design of the front plate and the middle plate also enhances the overall rigidity and modularity of the frame, making maintenance and component replacement convenient.

[0019] Optionally, the isolation drive module includes an isolation operating shaft rotatably mounted on the frame and an isolation spring drive plate fixedly connected to the isolation operating shaft. An isolation drive shaft pin is eccentrically mounted on the isolation spring drive plate. The grounding drive module includes a grounding operating shaft rotatably mounted on the frame and a grounding spring drive plate fixedly connected to the grounding operating shaft. A grounding drive shaft pin is eccentrically mounted on the grounding spring drive plate. The energy storage module further includes a guide sleeve, a guide seat, and a compression block. The guide seat is fixedly connected to the guide sleeve. The compression block is slidably mounted on the guide sleeve. The energy storage spring is sleeved on the guide sleeve and located between the guide seat and the compression block. The guide seat has a sliding groove adapted to the structure of the circumferential sidewall of the isolation drive shaft pin for insertion of the isolation drive shaft pin. The guide seat can rotate around the isolation drive shaft pin. The grounding drive shaft pin is fixedly connected to the compression block.

[0020] By adopting the above technical solution, the isolation drive shaft pin and the ground drive shaft pin cooperate with the guide seat and the compression block respectively to realize the compression and release of the energy storage spring. The design of the guide sleeve and the guide seat ensures the linearity and stability of the spring movement and can adapt to the offset of the guide sleeve caused by the rotation of the isolation spring drive plate and the ground spring drive plate, avoiding off-center loading and jamming. This modular energy storage structure not only improves the energy transfer efficiency, but also facilitates assembly and debugging, and enhances the reliability and maintainability of the entire operating mechanism.

[0021] Optionally, the isolation drive module includes an isolation operating shaft rotatably mounted on a frame and an isolation limiting plate fixedly connected to the isolation operating shaft. The frame includes a front plate with a limiting screw. The isolation operating shaft can rotate until the isolation limiting plate abuts against the limiting screw.

[0022] By adopting the above technical solution, a limit screw is set on the front plate, which works with the isolation limit plate to achieve precise positioning of the isolation operating shaft. The limit screw is easy to adjust and fix, and can adapt to different operating stroke requirements, improving the adaptability and operating accuracy of the mechanism. At the same time, the structure is simple, reducing manufacturing costs and assembly complexity.

[0023] Optionally, the indicator module further includes an indicator crank arm, a connecting plate, a transmission plate, and a transmission shaft. The indicator crank arm is fixedly connected to the output shaft, the transmission shaft is rotatably mounted on the frame, the indicator plate and the transmission plate are respectively fixedly connected to both ends of the transmission shaft, and both ends of the connecting plate are respectively rotatably connected to the indicator crank arm and the transmission plate.

[0024] By adopting the above technical solution, the indicator module accurately transmits the rotation of the output shaft to the indicator plate through the linkage of the indicator crank arm, connecting plate, transmission plate and transmission shaft, realizing intuitive display of the operation status. This transmission method has a stable structure and accurate transmission ratio, ensuring the consistency between the indication and the actual operation, and can avoid interference with other structures, improving the safety and monitorability of the equipment. At the same time, the modular design facilitates installation and subsequent maintenance.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The mechanism integrates isolation and grounding operations, significantly reducing the space occupied by the entire spring operating mechanism within the ring main unit; 2. The indicator module accurately transmits the rotation of the output shaft to the indicator plate through the linkage of the indicator arm, connecting plate, transmission plate and transmission shaft, realizing intuitive display of the operation status, and can avoid other structures to prevent interference, improving the safety and monitorability of the equipment. At the same time, the modular design facilitates installation and later maintenance. Attached Figure Description

[0033] The following combination Figures 1-6 This application will be described in further detail.

[0034] This application discloses an isolation spring operating mechanism for a primary and secondary fusion ring network box. (Refer to...) Figure 1 and Figure 2 The primary and secondary integrated ring main unit's isolation spring operating mechanism includes a frame 1, an output shaft 2, a rotating disk 3, an isolation drive module 4, a grounding drive module 5, an energy storage module 6, and an indicator module 7. The frame 1 serves as the supporting foundation for the entire mechanism. The output shaft 2 is rotatably mounted on the frame 1, and the rotating disk 3 is fixedly connected to the output shaft 2. The isolation drive module 4 and the grounding drive module 5 are mounted on the frame 1. The energy storage module 6 includes an energy storage spring 61. The isolation drive module 4 and the grounding drive module 5 are located on either side of the energy storage spring 61 and can compress it. The indicator module 7 is mounted on the frame 1 and includes an indicator plate 71 rotatably mounted on the frame 1. The output shaft 2 can drive the rotation of the indicator plate 71.

[0035] This structural layout integrates the isolation and grounding operation mechanisms, significantly reducing the space occupied by the entire spring operating mechanism within the ring network box. At the same time, the energy storage spring 61 provides power to the two operating modules, improving energy utilization efficiency and the structural compactness of the mechanism. The indicator module 7 can also reflect the operating status in real time, enhancing the monitorability and operational safety of the equipment.

[0036] Reference Figure 1The frame 1 serves as the mounting platform for the entire mechanism. It can be made of metal materials, such as carbon steel or aluminum alloy, through welding, casting, or machining. The frame 1 includes a front plate 12, a middle plate 11, and a back plate 13. The middle plate 11 is located between the front plate 12 and the back plate 13. The front plate 12 and the middle plate 11 are connected by support studs, and the middle plate 11 and the back plate 13 are also connected by support studs. The arrangement design between the middle plate 11 and the front plate 12 enhances the overall rigidity and modularity of the frame 1, facilitating maintenance and component replacement.

[0037] Reference Figure 1 and Figure 2 The output shaft 2 is rotatably mounted on the frame 1 via bearings. The output shaft 2 can be made of alloy steel, which has high strength and wear resistance. The output end of the output shaft 2 is located between the middle plate 11 and the back plate 13. A rotating disk 3 is fixedly connected to the output shaft 2. The rotating disk 3 is located between the middle plate 11 and the back plate 13. The rotating disk 3 can be fixed to the output shaft 2 by means of key connection or interference fit to ensure that the two rotate synchronously.

[0038] Reference Figure 1 The isolation drive module 4 includes an isolation operating shaft 41 rotatably mounted on the frame 1, which extends along the arrangement direction of the front plate 12 and the middle plate 11. The isolation operating shaft 41 is also rotatably mounted on the front plate 12 and the middle plate 11 via bearings, and its material can also be alloy steel. The front end of the isolation operating shaft 41 protrudes from the front plate 12 for operation.

[0039] Reference Figure 1 and Figure 3 The isolation drive module 4 also includes an isolation limiting plate 44 fixedly connected to the isolation operating shaft 41. The isolation limiting plate 44 can be made by forging and is fixed to the isolation operating shaft 41 by welding or keying. There are two isolation limiting plates 44, both of which are located between the front plate 12 and the middle plate 11, and are located on both sides of the energy storage spring 61 in the extension direction of the isolation operating shaft 41.

[0040] Reference Figure 2 and Figure 3 A limit stud 8 is threaded between the front plate 12 and the middle plate 11, and a limit screw 9 is also threaded on the front plate 12. When the energy storage spring 61 drives the isolation operating shaft 41 to rotate and reset, the isolation operating shaft 41 can rotate until both ends of the isolation limit plate 44 abut against the limit stud 8 and the limit screw 9 respectively.

[0041] Reference Figure 3The isolation drive module 4 also includes an isolation crank arm 42 fixedly connected to the isolation operating shaft 41. The isolation crank arm 42 can be made by forging and is fixed to the isolation operating shaft 41 by welding or keying. The isolation crank arm 42 is located between the middle plate 11 and the isolation limiting plate 44. An isolation transmission pin 43 is eccentrically fixed on the isolation crank arm 42. The isolation transmission pin 43 can be a cylindrical pin, which extends along the extension direction of the isolation operating shaft 41 and is made of stainless steel, which has good corrosion resistance.

[0042] Reference Figure 3 The middle plate 11 has a limiting hole 111 extending around the central axis of the isolation operation shaft 41. The isolation transmission pin 43 slides within the limiting hole 111 and can slide until it abuts against the wall of the limiting hole 111, thus limiting the range of motion of the isolation transmission pin 43 and effectively preventing over-rotation or positional deviation during the isolation operation. This limiting method has a stable structure, is easy to adjust, and can effectively prevent damage to the mechanism or misoperation caused by excessive operation.

[0043] Reference Figure 2 and Figure 3 The rotating disk 3 has an oblong hole 31 for the isolation transmission pin 43 to be inserted and slide. The design of the oblong hole 31 allows the isolation transmission pin 43 a certain degree of freedom of movement, which is convenient for assembly and fine adjustment during operation. When the isolation operating shaft 41 rotates, the isolation crank arm 42 rotates accordingly, driving the isolation transmission pin 43 to slide in the oblong hole 31, thereby driving the rotating disk 3 to rotate in the forward direction and realizing isolation and closing. This transmission method has a simple and reliable structure and occupies little space.

[0044] Reference Figure 2 To prevent interference between the isolation transmission pin 43 and the rotating disk 3 during operation of the grounding drive module 5, a clearance hole 32 is provided on the wall of the oblong hole 31. When the grounding drive module 5 drives the rotating disk 3 to rotate in the opposite direction, the isolation transmission pin 43 can slide from the oblong hole 31 into the clearance hole 32, achieving effective clearance during the operation of the grounding drive module 5. This helps prevent the mechanism from jamming, improves the smoothness of operation and the reliability of the mechanism, and simplifies the structural design, reducing manufacturing and assembly difficulties.

[0045] Reference Figure 3 The structure of the grounding drive module 5 is similar to that of the isolation drive module 4, including a grounding operation shaft 51, a grounding limit plate 56, a grounding crank arm 52 and a grounding transmission pin 53, which will not be described in detail here. The grounding transmission pin 53 is inserted into and slides in the second oblong hole 31 opened on the middle plate 11.

[0046] Reference Figure 2 and Figure 3The rotating disk 3 has a strip-shaped hole 33 for the grounding transmission pin 53 to be inserted and slide. When the grounding operating shaft 51 rotates, the grounding crank arm 52 rotates accordingly, causing the grounding transmission pin 53 to slide within the strip-shaped hole 33, thereby driving the rotating disk 3 to rotate in the opposite direction and realizing grounding closing. This transmission method has a simple and reliable structure and occupies little space.

[0047] Reference Figure 2 and Figure 3 A strip-shaped hole 33 penetrates the circumferential sidewall of the rotating disk 3. A clearance arc surface 34 is formed on the circumferential sidewall of the rotating disk 3. When the energy storage spring 61 drives the grounding operating shaft 51 to rotate and reset, the grounding operating shaft 51 can rotate until the grounding transmission pin 53 slides out of the strip-shaped hole 33. When the isolation drive module 4 drives the rotating disk 3 to rotate in the forward direction, the clearance arc surface 34 is located outside the movement path of the grounding transmission pin 53 relative to the rotating disk 3. This structure avoids interference and wear of the grounding drive module 5 in the non-operating state. The design of the clearance arc surface 34 further optimizes the motion trajectory, reduces unnecessary friction and resistance, and helps to extend the service life of the mechanism and improve its motion accuracy.

[0048] Reference Figure 3 and Figure 4 The energy storage module 6 also includes a guide sleeve 62, a guide seat 63, and a compression block 64. The guide seat 63 is fixedly connected to the guide sleeve 62, the compression block 64 is slidably mounted on the guide sleeve 62 along the extension direction of the guide sleeve 62, and the energy storage spring 61 is sleeved on the guide sleeve 62 and located between the guide seat 63 and the compression block 64.

[0049] Reference Figure 4 and Figure 5 The isolation drive module 4 also includes an isolation spring drive plate 45 fixedly connected to the isolation operating shaft 41. Two isolation spring drive plates 45 are provided, located on either side of the energy storage spring 61 and between the two isolation limiting plates 44 in the extending direction of the isolation operating shaft 41. An isolation drive shaft pin 46 is eccentrically fixed between the two isolation spring drive plates 45, extending along the extending direction of the isolation operating shaft 41. A sliding groove 631 is provided on the guide seat 63, which is adapted to the structure of the circumferential sidewall of the isolation drive shaft pin 46 for insertion. The groove wall of the sliding groove 631 can slide against the circumferential sidewall of the isolation drive shaft pin 46, allowing the guide seat 63 to rotate around the isolation drive shaft pin 46.

[0050] Reference Figure 3The grounding drive module 5 also includes a grounding spring drive plate 54 fixedly connected to the grounding operation shaft 51. There are two grounding spring drive plates 54, which are located on both sides of the energy storage spring 61 and between the two grounding limit plates 56 in the extension direction of the grounding operation shaft 51. A grounding drive shaft pin 55 is eccentrically fixed between the two grounding spring drive plates 54, and the grounding drive shaft pin 55 is fixedly connected to the compression block 64.

[0051] When the isolation operating shaft 41 or the grounding operating shaft 51 rotates, the guide seat 63 and the compression block 64 move through the isolation drive shaft pin 46 and the grounding drive shaft pin 55 respectively, thereby compressing the energy storage spring 61 and storing energy. The design of the guide sleeve 62 and the guide seat 63 ensures the linearity and stability of the spring movement, and can adapt to the offset of the guide sleeve 62 caused by the rotation of the isolation spring drive plate 45 and the grounding spring drive plate 54, avoiding off-center loading and jamming. This modular energy storage structure not only improves energy transfer efficiency, but also facilitates assembly and debugging, and enhances the reliability and maintainability of the entire operating mechanism.

[0052] Reference Figure 1 and Figure 6 The indicator module 7 also includes an indicator crank arm 72, a connecting plate 73, a transmission plate 74, and a transmission shaft 75. The indicator crank arm 72 is fixedly connected to the output shaft 2 and located between the front plate 12 and the middle plate 11. The transmission shaft 75 extends along the arrangement direction of the front plate 12 and the middle plate 11, and is rotatably mounted on the front plate 12 and the middle plate 11, with its front end extending out of the front plate 12. The indicator plate 71 and the transmission plate 74 are fixedly connected to the two ends of the transmission shaft 75, respectively. The indicator plate 71 is located on the side of the front plate 12 away from the middle plate 11, and the transmission plate 74 is located between the front plate 12 and the middle plate 11. The two ends of the connecting plate 73 are rotatably connected to the indicator crank arm 72 and the transmission plate 74, respectively.

[0053] When the output shaft 2 rotates in the forward direction, the indicator crank arm 72 rotates accordingly, driving the transmission plate 74 to rotate via the connecting plate 73, which in turn drives the transmission shaft 75 and the indicator plate 71 to rotate. The indicator plate 71 rotates to point towards the isolation drive module 4, and vice versa, it rotates to point towards the grounding drive module 5. If both isolation and grounding are in the open state, the indicator plate 71 points to the middle, providing a clear display of the operating status. This transmission method offers structural stability and accurate transmission ratio, ensuring consistency between the indication and actual operation. It also avoids interference with other structures, improving equipment safety and monitorability. Furthermore, the modular design facilitates installation and subsequent maintenance.

[0054] The working principle of the isolation spring operating mechanism of the primary and secondary fusion ring network box in this embodiment is as follows: When the isolation operating shaft 41 rotates clockwise, it drives the rotating disk 3 to rotate clockwise, and the energy storage spring 61 is compressed to store energy, thereby realizing isolation closing; when the isolation operating shaft 41 is released, the energy storage spring 61 is released, driving the isolation operating shaft 41 to rotate counterclockwise to reset, and at the same time, the rotating disk 3 rotates counterclockwise to reset, until the isolation operating shaft 41 rotates to the point where the isolation limit plate 44 abuts against the limit stud 8 and the limit screw 9, and at the same time, the isolation transmission pin 43 abuts against the hole wall of the limit hole 111, thereby realizing isolation opening. When the grounding operating shaft 51 rotates clockwise, it drives the rotating disk 3 to rotate counterclockwise, compressing the energy storage spring 61 to store energy and realize grounding closing; when the grounding operating shaft 51 is released, the energy storage spring 61 is released, driving the grounding operating shaft 51 to rotate counterclockwise to reset, while the rotating disk 3 rotates clockwise to reset, until the grounding operating shaft 51 rotates until the grounding limit plate 56 abuts against the limit stud 8 and the limit screw 9, and the grounding transmission pin 53 abuts against the hole wall of the limit hole 111.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
