Description

Technical Field

[0001] This utility model relates to the field of electrical testing technology, and in particular to a protective structure for an electrical equipment operation and maintenance strategy generation device. Background Technology

[0002] In the field of electrical testing technology, the electrical equipment operation and maintenance strategy generation device plays an irreplaceable role as a key piece of equipment. This device utilizes data processing and analysis technologies, combined with professional knowledge and experience, to provide decision support for the operation and maintenance of electrical equipment. Its core architecture typically consists of a data collection module, an analysis and modeling module, and a strategy generation module. Through the collaborative work of these modules, real-time monitoring and intelligent analysis of the operating status of electrical equipment are achieved, thereby generating scientifically sound and reasonable operation and maintenance strategies.

[0003] However, existing electrical equipment operation and maintenance strategy generation devices (including but not limited to line fault location and repair devices and power distribution equipment operation and maintenance devices) have significant shortcomings in hardware design. Specifically, such devices typically consist of multiple modules integrated into a single housing and fixed inside the electrical equipment. The housing is usually fixed using traditional methods such as bolts and clips. While these methods ensure the device's robustness, they cause considerable inconvenience during actual maintenance.

[0004] For example, CN213517398U discloses a line fault location and repair device. This device, through the design of specific structures such as a repair box, support frame, top cover, protection mechanism, and movement adjustment mechanism, aims to improve the efficiency of line fault location and repair.

[0005] However, in practical applications, this device still has some shortcomings. For example, although it has a mobile adjustment function, facilitating fault location and repair in different locations, its overall design may still be relatively bulky, making rapid deployment and relocation difficult. Furthermore, for line faults in complex environments, the device may lack sufficient adaptability and flexibility, making it difficult to meet diverse operation and maintenance needs. At the same time, the existing enclosure design also has significant shortcomings in terms of adaptability and protection. In complex and changing working environments, the device enclosure cannot effectively resist external mechanical damage, thus shortening the equipment's lifespan. In addition, due to the lack of a robust locking mechanism, the device may shift its position due to unexpected vibrations during operation, further increasing the risks and uncertainties of operation and maintenance.

[0006] Similar to the new type of safety protection device for power distribution automation operation and maintenance disclosed in CN218498637U, this device aims to improve the safety and convenience of power distribution equipment operation and maintenance by designing power distribution operation and maintenance units, lifting and adjusting units, and manual stretching units.

[0007] However, the device also has some technical drawbacks in practical applications. For example, although its lifting and adjusting unit can lower the distribution box to ground level for maintenance personnel to inspect and maintain, the process may still be time-consuming, and for the maintenance of high-altitude power distribution equipment, maintenance personnel still need to climb to a certain height to operate, which poses certain safety hazards.

[0008] In addition, the device may lack sufficient rapid response capability when dealing with sudden failures or emergencies, making it difficult to meet the real-time operation and maintenance needs of the power system.

[0009] In summary, existing line fault location and repair devices and power distribution equipment maintenance devices still have certain shortcomings in improving maintenance efficiency, safety, and convenience. Therefore, developing a more efficient, safe, and convenient line fault location and repair device and power distribution equipment maintenance device is of great significance for improving the stability and reliability of power systems. Summary of the Invention

[0010] The technical problem to be solved by this utility model is to provide a protective structure for an electrical equipment operation and maintenance strategy generation device, which solves the technical problem of inconvenient hardware maintenance of electrical equipment operation and maintenance strategy generation devices in the field of electrical testing technology. Specifically, the shell design of the existing device requires the entire device to be disassembled during maintenance, which makes the maintenance process cumbersome, time-consuming and costly, and may lead to excessive downtime of the equipment, affecting the stable operation of the power system.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A protective structure for an electrical equipment operation and maintenance strategy generation device mainly includes an operation and maintenance box, a protective mechanism, and a set of symmetrically arranged linkage components. The operation and maintenance box is designed to slide vertically inside the protective mechanism. This design allows the operation and maintenance box to be easily extended when maintenance is needed, and to be safely retracted into the protective mechanism for protection when not needed.

[0013] The protective mechanism serves as the supporting and protective frame for the entire structure. Its upper end is open and equipped with a set of movable end caps. Driven by the linkage assembly, these end caps can open in an arc trajectory, facilitating the extension and retraction of the maintenance box.

[0014] The protective mechanism also includes a protective frame, end caps, and connecting plates. The protective frame has openings on the top, bottom, and three sides of the front, facilitating both the extension and retraction of the maintenance box and front-facing wiring operations. The linkage assemblies, key components for the stable extension and retraction of the maintenance box, are symmetrically arranged on both sides of the protective mechanism. Each linkage assembly includes a pivot, a first link, a second link, a third link, a fourth link, and a gear. The pivot, serving as the rotation center of the linkage assembly, has a regular hexagonal cross-section to ensure stable connection with each link and gear, prevent relative rotation, and guarantee accurate force transmission.

[0015] The first link, gear, and third link are all connected to the rotating shaft. Two opposing gears mesh with each other to achieve coordinated movement of the link assembly. The other end of the first link is rotatably connected to the end cover, allowing the end cover to open in an arc trajectory as the first link swings. One end of the third link is rotatably connected to the second link, and the other end is rotatably connected to the maintenance box. Thus, when the rotating shaft rotates, the coordinated action of the links drives the maintenance box to move vertically within the protective mechanism.

[0016] The fourth link is set parallel to the first link, with one end rotatably connected to the protective mechanism and the other end rotatably connected to the maintenance box. This design ensures that the end cover can remain horizontal during the operation and also enhances the stability of the maintenance box during the extension and retraction process.

[0017] Furthermore, to further enhance the safety of operation and maintenance, this invention also incorporates a locking structure. This locking structure includes a locking part and a clamping plate. The locking part is configured to screw into the clamping plate, preventing horizontal movement. When the maintenance box extends to a certain position, the locking structure secures it, preventing accidental retraction and ensuring the safe conduct of operation and maintenance.

[0018] Furthermore, a heat dissipation cover is fastened to the upper end of the maintenance box. The heat dissipation cover is provided with multiple heat dissipation holes to enhance air convection, improve heat dissipation efficiency, and ensure the normal operation of the electronic components inside the maintenance box.

[0019] Furthermore, both the protective mechanism and the linkage assembly are made of high-strength metal materials to ensure the stability and durability of the structure.

[0020] In summary, the technical solution of this utility model, through the ingenious design of the linkage assembly, the optimization of the protection mechanism, and the introduction of the locking structure, realizes the convenience and efficiency of the electrical equipment operation and maintenance strategy generation device on the hardware side, providing a strong guarantee for the stable operation of the power system.

[0021] The protective structure for the electrical equipment operation and maintenance strategy generation device provided by this utility model has the following beneficial effects:

[0022] 1. This utility model effectively solves the problem of inconvenient hardware maintenance of electrical equipment operation and maintenance strategy generation device. Through innovative linkage component design, it realizes the rapid and stable extension and retraction of the operation and maintenance box, avoiding the cumbersome, time-consuming and high cost brought about by the traditional shell disassembly method.

[0023] 2. The design of the connecting rod assembly of this utility model enables the opening of the end cover and the extension of the maintenance box to be carried out simultaneously, which greatly improves the convenience and efficiency of device maintenance.

[0024] 3. The hexagonal cross-section fit design between the shaft, connecting rod, and gear in this utility model eliminates the radial runout problem of traditional round shafts, significantly improves the force transmission accuracy and structural stability, further enhances the reliability and durability of the device, and extends the service life of the equipment.

[0025] 4. The introduction of the locking structure in this utility model provides a stable locking function for the maintenance box, avoiding positional displacement caused by accidental vibration, effectively preventing accidental movement of the maintenance box during operation, and improving the safety of maintenance operations.

[0026] 5. The introduction of the locking structure in this utility model makes operation and maintenance safer and more reliable, and reduces the risks in the operation and maintenance process.

[0027] 6. Through innovative linkage assembly design and synchronous drive mechanism, this utility model realizes the stable extension and retraction of the maintenance box within the protective mechanism, as well as the opening of the end cover, which greatly improves the adaptability of the device in complex environments and effectively protects the maintenance box from external mechanical damage.

[0028] 7. The device of this utility model has better adaptability in complex environments and can meet the usage needs in different scenarios.

[0029] 8. The implementation of this utility model shortens maintenance time, reduces maintenance costs, and reduces equipment downtime, thereby ensuring the continuous and stable operation of the power system.

[0030] 9. The protective structure of the electrical equipment operation and maintenance strategy generation device of this utility model significantly improves the convenience of maintenance, enhances the structural stability and durability, improves the safety of operation and maintenance, adapts to complex environments, shortens maintenance time, and reduces costs through a series of innovative designs, thus providing a strong guarantee for the stable operation of the power system.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments:

[0039] Example 1

[0040] Please see Figures 1 to 4 An embodiment of this utility model provides a protective structure for an electrical equipment operation and maintenance strategy generation device, including an operation and maintenance box 1, a protective mechanism 2, and two linkage assemblies 3.

[0041] The upper end of the protective mechanism 2 is open and closed with a set of end caps 23. The maintenance box 1 can be vertically slidably installed inside the protective mechanism 2, so that when not in use, the maintenance box 1 can be stored inside the protective mechanism 2 and protected.

[0042] In this embodiment, each linkage assembly 3 includes a rotating shaft 31, a first linkage 32, a lifting component, and a gear 36. The lifting component includes a second linkage 33 and a third linkage 34. The second linkage 33 and the third linkage 34 are rotatably connected by a pivot pin, and one end of the third linkage 34 is rotatably connected to the maintenance box 1.

[0043] Furthermore, the first link 32, gear 36, and lifting component are all connected to the rotating shaft 31 to facilitate the synchronous movement of the first link 32, gear 36, and lifting component. Two opposing gears 36 mesh with each other, and the other end of each first link 32 is rotatably connected to an end cover 23, so that the two end covers 23 can move in opposite directions along an arc trajectory as a set of first links 32 swings. The other end of the lifting component is connected to the maintenance box 1, so that the maintenance box 1 can be driven to move vertically within the protective mechanism 2.

[0044] In an optional embodiment, the linkage assembly 3 further includes a fourth linkage 35, which is arranged parallel to the first linkage 32, with one end of the fourth linkage 35 rotatably connected to the protective mechanism 2 and the other end rotatably connected to the maintenance box 1.

[0045] This design allows the end cap 23 to remain horizontal as it moves along the arc-shaped trajectory of the first link 32.

[0046] The protective mechanism 2 includes a protective frame 21, an end cap 23, and a connecting plate 22. The connecting plate 22 is connected to the protective frame 21 to support the protective mechanism 2. The protective frame 21 has openings on the top, bottom, and three sides of the front to facilitate the top and bottom extension of the maintenance box 1 and front wiring.

[0047] Both sides of the protective frame 21 are provided with through slots 211, which correspond to the trajectories of the fourth link 35 and the first link 32, so that the link assembly 3 will not be interfered with by the protective frame 21 during the movement.

[0048] In an optional embodiment, the device further includes a locking structure comprising a locking part 5 and a clamping plate 4, the locking part 5 being configured to screw into the clamping plate 4 to block its horizontal movement, thereby securing the maintenance box 1 to a certain position by the locking structure to prevent it from being accidentally retracted.

[0049] To limit the relative movement between the components of the linkage assembly 3, the cross-section of the shaft 31 is a regular hexagon, and the first link 32, the second link 33 and the gear 36 connected to it are all provided with corresponding hexagonal holes. This design can prevent relative rotation between the shaft 31 and each link and gear 36, and ensure the accuracy of force transmission.

[0050] It should be noted that a rotating pin 311 is provided on the end of the rotating shaft 31 facing the protective frame 21. The rotating pin 311 is rotatably connected to the inner wall of the protective frame 21, so that the rotating shaft 31 can rotate stably inside the protective frame 21.

[0051] The rear sidewall of the protective frame 21 extends vertically upward, so that one side of the end cap 23 contacts it, so that when the maintenance box 1 is retracted, the end cap 23 can tightly seal the upper end of the protective mechanism 2.

[0052] The upper end of the maintenance box 1 is fitted with a heat dissipation cover 11, which is used to dissipate the heat generated by the maintenance box 1 during operation and ensure its normal operation.

[0053] When performing maintenance on this device, first rotate the locking parts 5 located on both sides of the protective frame 21 so that the two locking parts 5 can disengage from the locking state of the clamping plate 4. Then, pull the two end caps 23 on the upper part of the protective frame 21 to the sides and slide them open. At this time, the first connecting rod 32 connected to the end cap 23 swings, causing the rotating shaft 31 connected to its other end to rotate. The rotation of the rotating shaft 31 drives the second connecting rod 33, the third connecting rod 34 and the gear 36 connected to it to move. Since the two opposing gears 36 mesh with each other, the two connecting rod assemblies 3 will move in coordination. The movement of the second connecting rod 33 and the third connecting rod 34 in the lifting component drives the maintenance box 1 to move vertically in the protective mechanism 2, so that while the end caps 23 open to the sides, the maintenance box 1 can extend out of the protective mechanism 2 to facilitate the opening of the heat dissipation cover 11 for maintenance. After the work is completed, squeeze the two end caps 23 so that the connecting rod assembly 3 drives it to move downward and retract into the protective mechanism 2 for effective protection. When the maintenance box 1 returns to the appropriate position, it can be fixed by the locking structure. At this time, the locking part 5 is screwed into the clamping plate 4, blocking the horizontal movement of the clamping plate 4, thereby preventing the position of the maintenance box 1 from changing during operation.

[0054] Example 2

[0055] In another preferred embodiment, based on the above embodiment 1, this embodiment provides a protective structure for an electrical equipment operation and maintenance strategy generation device, which mainly includes an operation and maintenance box 1, a protective mechanism 2, and a set of symmetrically arranged linkage assemblies 3.

[0056] The protective mechanism 2 consists of a protective frame 21, an end cap 23, and a connecting plate 22. The protective frame 21 has openings on the top, bottom, and three sides of the front, facilitating the extension of the maintenance box 1 from the top and bottom and the front wiring. The end cap 23 is located at the top of the protective mechanism 2 and can be opened.

[0057] The linkage assembly 3 includes a rotating shaft 31, a first connecting rod 32, a second connecting rod 33, a third connecting rod 34, a fourth connecting rod 35, and a gear 36. The rotating shaft 31 has a regular hexagonal cross-section, and the first connecting rod 32, the second connecting rod 33, and the gear 36 connected to it all have corresponding hexagonal holes to ensure a stable connection between the rotating shaft 31 and each connecting rod and gear 36, preventing relative rotation. The first connecting rod 32, the gear 36, and the lifting components (the second connecting rod 33 and the third connecting rod 34) are all connected to the rotating shaft 31 for synchronous movement. Two opposing gears 36 mesh with each other to achieve coordinated movement of the linkage assembly 3.

[0058] The other end of the first link 32 is rotatably connected to the end cover 23, allowing the end cover 23 to open in an arc trajectory as the first link 32 swings. One end of the third link 34 is rotatably connected to the second link 33, and the other end is rotatably connected to the maintenance box 1. Thus, when the rotating shaft 31 rotates, the coordinated action of the links drives the maintenance box 1 to move vertically within the protective mechanism 2. The fourth link 35 is arranged parallel to the first link 32, with one end rotatably connected to the protective mechanism 2 and the other end rotatably connected to the maintenance box 1. This design ensures that the end cover 23 remains horizontal during movement and also enhances the stability of the maintenance box 1 during extension and retraction.

[0059] In addition, this utility model also incorporates a locking structure, including a locking part 5 and a clamping plate 4. The locking part 5 is configured to screw into the clamping plate 4 to prevent its horizontal movement. Thus, when the maintenance box 1 extends to a certain position, it is fixed by the locking structure to prevent accidental retraction and ensure the safe operation of maintenance procedures.

[0060] When maintaining this device, first rotate the locking parts 5 located on both sides of the protective frame 21 to release the locking state. Then, pull the two end caps 23 on the upper part of the protective frame 21 to the sides to slide open. At this time, the first connecting rod 32 connected to the end cap 23 swings, driving the rotating shaft 31 to rotate, which in turn drives the second connecting rod 33, the third connecting rod 34, and the gear 36 to move. Since the two opposing gears 36 mesh with each other, the two connecting rod assemblies 3 will move in coordination. The movement of the second connecting rod 33 and the third connecting rod 34 in the lifting component drives the maintenance box 1 to move vertically within the protective mechanism 2, so that while the end caps 23 open to the sides, the maintenance box 1 can extend out of the protective mechanism 2 for maintenance operations. After the work is completed, squeeze the two end caps 23 to drive the connecting rod assemblies 3 to move the maintenance box 1 downward and retract it into the protective mechanism 2 for effective protection. When the maintenance box 1 returns to the appropriate position, it is fixed by the locking structure. At this time, the locking part 5 is screwed into the clamping plate 4 to prevent the clamping plate 4 from moving horizontally and to prevent the maintenance box 1 from changing position during operation.

[0061] Example 3

[0062] In another preferred embodiment, based on the above embodiment 2, the present invention provides a protective structure for an electrical equipment operation and maintenance strategy generation device, the specific implementation of which is described in detail below.

[0063] The protective structure mainly includes a maintenance box 1, a protective mechanism 2, and a set of symmetrically arranged linkage assemblies 3.

[0064] The maintenance box 1 is vertically slidably installed inside the protective mechanism 2 to house the components of the electrical equipment maintenance strategy generation device. The upper end of the protective mechanism 2 is open and equipped with a set of end caps 23 for sealing and protecting the maintenance box 1.

[0065] The linkage assembly 3 is used to drive the maintenance box 1 to extend and retract within the protective mechanism 2, and to drive a set of end covers 23 to open. Specifically, the linkage assembly 3 includes a first link 32 rotatably mounted on the end cover 23, and the other end of the first link 32 is mounted with a lifting component and a gear 36 via a rotating shaft 31. The lifting component includes a second link 33 and a third link 34 rotatably connected together, the other end of the second link 33 being rotatably connected to the first link 32, and the other end of the third link 34 being rotatably connected to the maintenance box 1. A pair of gears 36 of the linkage assembly 3 mesh with each other to achieve coordinated movement of the two linkage assemblies 3.

[0066] In addition, the linkage assembly 3 also includes a fourth linkage 35, which is arranged parallel to the first linkage 32. One end of the fourth linkage 35 is rotatably connected to the end cap 23 of the protective mechanism 2, and the other end is rotatably connected to the back plate of the protective frame 21 of the protective mechanism 2. This design ensures that the end cap 23 can remain horizontal during operation, and also enhances the stability of the maintenance box 1 during extension and retraction.

[0067] To ensure stable connection between the components of the linkage assembly 3, the first link 32, the second link 33, the third link 34, and the gear 36 are all provided with hexagonal holes that match the cross-section of the rotating shaft 31. A rotating pin 311 is provided on the end of the rotating shaft 31 facing the protective frame 21. The rotating pin 311 is rotatably connected to the inner wall of the back plate of the protective frame 21, so that the rotating shaft 31 can rotate stably within the protective frame 21.

[0068] The protective mechanism 2 includes a protective frame 21 with openings on the top, bottom, and front sides. An end cap 23 is installed on the top, and a connecting plate 22 is installed on the bottom to support the protective mechanism 2. Through slots 211 are provided on both sides of the protective frame 21, and the through slots 211 correspond to the tracks of the fourth connecting rod 35 and the first connecting rod 32 to ensure that the connecting rod assembly 3 is not interfered with by the protective frame 21 during movement.

[0069] The protective structure also includes a locking structure installed at the lower end of the end cover 23. The locking structure includes a clamping plate 4, which is installed at the lower end of the end cover 23. A groove is provided at the lower end of the clamping plate 4, and a locking part 5 is installed in the groove.

[0070] The locking part 5 passes through the protective frame 21 and screws into the side of the maintenance box 1, and is rotatably connected to it. The clamp 4 cooperates with the locking part 5 to lock the maintenance box 1 and prevent it from moving accidentally during operation.

[0071] The upper end of the maintenance box 1 is fitted with a heat dissipation cover 11 to dissipate the heat generated by the maintenance box 1 during operation.

[0072] The front of the maintenance box 1 has a wiring port for connecting to external devices to enable data transmission and interaction.

[0073] Both the protective mechanism 2 and the linkage assembly 3 are made of high-strength metal materials to ensure the stability and durability of the structure and adapt to various complex working environments.

[0074] When maintaining this device, first release the locking structure, then operate the end cover 23 to drive the linkage assembly 3 to extend the maintenance box 1 into the protective mechanism 2 for maintenance operations. After the work is completed, operate the end cover 23 again to drive the linkage assembly 3 to retract the maintenance box 1 into the protective mechanism 2, and lock it with the locking structure to ensure its stability and safety.

[0075] Example 4

[0076] In another preferred embodiment, based on embodiments 1, 2, and 3 above, the design of the linkage assembly 3 can be further optimized. For example, a lighter material can be used to manufacture the linkage assembly 3 to reduce the weight of the entire protective structure; or the length ratio of each link in the linkage assembly 3 can be adjusted to optimize the extension and retraction speed of the maintenance box 1. These optimized designs all fall within the protection scope of this utility model and can be flexibly adjusted according to actual needs.

[0077] Through the description of the above four specific embodiments, those skilled in the art can successfully reproduce the technical solution of this utility model and fully understand its innovativeness and practicality. The protective structure of the electrical equipment operation and maintenance strategy generation device of this utility model, through the ingenious design of the linkage assembly 3, the optimization of the protective mechanism 2, and the introduction of the locking structure, achieves convenience and efficiency in hardware-side maintenance of the electrical equipment operation and maintenance strategy generation device, providing strong support for the stable operation of the power system.

[0078] In a preferred embodiment, the linkage assembly 3 includes a first linkage 32 rotatably mounted on the end cover 23. The other end of the first linkage 32 is equipped with a lifting component and a gear 36 via a rotating shaft 31. The lifting component includes a second linkage 33 and a third linkage 34 rotatably connected together. The other end of the second linkage 33 is rotatably connected to the first linkage 32, and the other end of the third linkage 34 is rotatably connected to the maintenance box 1. A pair of gears 36 in a set of linkage assemblies 3 mesh with each other. The above configuration enables the smooth lifting and positioning of the maintenance box 1. Through the meshing transmission of the gears 36, the synchronous movement of the linkage assemblies 3 on both sides is ensured, improving the stability and reliability of the lifting process and providing solid support and convenient operating conditions for maintenance operations.

[0079] In a preferred embodiment, the linkage assembly 3 further includes a fourth linkage 35, which is arranged parallel to the first linkage 32. One end of the fourth linkage 35 is rotatably connected to the end cap 23 of the protective mechanism 2, and the other end is rotatably connected to the back plate of the protective frame 21 of the protective mechanism 2. This arrangement, together with the first linkage 32, forms a stable structure, enhances rigidity, prevents the maintenance box 1 from swaying when it extends and retracts, and ensures accurate maintenance. The coordinated movement of the fourth linkage 35 allows the end cap 23 to open horizontally, improving convenience, avoiding tilting and jamming, and also sharing the force of the first linkage 32, making the linkage assembly 3 evenly stressed, extending the component life, and improving the load-bearing capacity. At the same time, it optimizes the movement trajectory of the maintenance box 1, making its extension and retraction smoother and improving maintenance efficiency.

[0080] In a preferred embodiment, the first connecting rod 32, the second connecting rod 33, the third connecting rod 34, and the gear 36 are all provided with hexagonal holes that are adapted to the cross-section of the rotating shaft 31. This arrangement allows the first connecting rod 32, the second connecting rod 33, the third connecting rod 34, and the gear 36 to be stably mounted on the rotating shaft 31, avoiding relative rotation and improving the stability of the mechanism and the accuracy of transmission.

[0081] In a preferred embodiment, the protective mechanism 2 includes a protective frame 21 with openings on the top, bottom, and front sides. An end cap 23 is installed on the top, and a connecting plate 22 is installed on the bottom to support the protective mechanism 2. These features allow the protective frame 21 to be easily installed and disassembled. The end cap 23 is designed to be openable and closable, facilitating internal maintenance and repair. The connecting plate 22 is fixed to the main body of the equipment by bolts or other fasteners to ensure the stability of the protective mechanism 2.

[0082] In a preferred embodiment, through slots 211 are provided on both sides of the protective frame 21, and the through slots 211 correspond to the trajectories of the fourth connecting rod 35 and the first connecting rod 32. This arrangement provides sufficient space for the movement of the connecting rod assembly 3, ensuring that the connecting rod can pass smoothly when driving the maintenance box 1 to extend and retract, avoiding interference with the protective frame 21, and ensuring the smoothness of maintenance operations. At the same time, the through slots 211 facilitate observation and maintenance, further improving the stability of the movement of the maintenance box 1 and the convenience of use.

[0083] In a preferred embodiment, the protective structure further includes a locking structure installed at the lower end of the end cover 23. The locking structure includes a clamping plate 4, which is installed at the lower end of the end cover 23. A groove is provided at the lower end of the clamping plate 4, and a locking part 5 is installed in the groove. The locking part 5 passes through the protective frame 21 and is screwed into the side of the maintenance box 1, where it is rotatably connected. The clamping plate 4 and the locking part 5 cooperate to lock the maintenance box 1. The above settings effectively prevent the maintenance box 1 from being accidentally opened during transportation or installation, enhancing the stability and safety of the overall structure. At the same time, the rotation locking design of the locking part 5 facilitates quick installation and disassembly by users, improving maintenance efficiency and convenience.

[0084] In a preferred embodiment, a rotating pin 311 is provided on one end of the rotating shaft 31 facing the protective frame 21. The rotating pin 311 is rotatably connected to the inner wall of the back plate of the protective frame 21. The back plate of the protective frame 21 extends upward in the vertical direction, so that one side of the end cap 23 contacts it. The above arrangement ensures the stable rotation of the rotating shaft 31 within the protective frame 21. At the same time, the end cap 23 is tightly attached to the back plate due to gravity, which enhances the stability of the structure and effectively prevents dust and other impurities from entering the interior of the protective frame 21, thus ensuring the normal operation of the equipment.

[0085] In a preferred embodiment, a heat dissipation cover 11 is fastened to the upper end of the maintenance box 1, and a wiring port is provided on the front of the maintenance box 1 for connecting to external devices. These features not only facilitate heat dissipation for maintenance personnel inside the box but also ensure convenient wiring operations. A status indicator light is also installed on the side of the maintenance box 1 to display the real-time operating status of the equipment, improving maintenance efficiency.

[0086] In the preferred embodiment, both the protective mechanism 2 and the connecting rod assembly 3 are made of high-strength metal materials. The above configuration ensures that the protective mechanism 2 can effectively resist external impacts and maintain the stability of the structure. At the same time, the high strength of the connecting rod assembly 3 ensures its transmission efficiency and durability, thereby improving the overall safety and service life of the equipment.

[0087] In summary, the protective structure for the electrical equipment operation and maintenance strategy generation device provided by this utility model effectively solves the technical problem of inconvenient hardware maintenance of electrical equipment operation and maintenance strategy generation devices in the field of electrical testing technology. Addressing the limitations of existing devices that require complete disassembly of the casing, resulting in cumbersome, time-consuming, and costly maintenance, and potentially causing excessive equipment downtime and affecting the stable operation of the power system, this utility model successfully overcomes these limitations.

[0088] This utility model employs an innovative linkage assembly 3 design. Through the coordinated action of the rotating shaft 31, the first linkage 32, the second linkage 33, the third linkage 34, the fourth linkage 35, and the gear 36, the stable extension and retraction of the maintenance box 1 within the protective mechanism 2, as well as the opening of the end cover 23, are achieved. This design is novel in the existing protective structures of electrical equipment maintenance strategy generation devices.

[0089] The linkage assembly 3 in this invention enables the opening of the end cover 23 and the extension of the maintenance box 1 to proceed synchronously. This synchronous driving mechanism improves operational convenience and enhances the overall structural stability, a feature rarely seen in existing technologies. Furthermore, this invention incorporates a locking structure 5 in its protective structure to secure the maintenance box when it extends to a certain position, preventing accidental retraction and improving the safety of maintenance operations—a feature also uncommon in existing technologies.

[0090] The hexagonal cross-section mating design between the rotating shaft 31, the connecting rod and the gear 36 eliminates the radial runout problem of the traditional round shaft, significantly improving the force transmission accuracy and structural stability. Through the innovative design of the connecting rod assembly 3 and the synchronous drive mechanism, the present utility model realizes the linkage operation of the operation and maintenance box 1 and the end cover 23, greatly enhancing the convenience and efficiency of device maintenance. The introduction of the anti-lock structure 5 not only enhances the safety of operation and maintenance operations, but also enables the device to have better adaptability in complex environments.

[0091] In summary, the present utility model not only innovates in individual components or structures, but also organically combines these innovative components or structures to form a complete and creative solution. This solution has achieved remarkable results in improving the convenience, safety and stability of the protection structure of the electrical equipment operation and maintenance strategy generation device.
