Description

Technical Field

[0001] This invention relates to the field of ring main units, specifically to an intelligent protective ring main unit. Background Technology

[0002] Ring main units (RMUs) are core basic power equipment in urban power distribution networks and industrial and mining enterprise power supply systems. They are mainly used for cable branching, ring network power supply, and line protection and control. They are characterized by high integration, small footprint, and neat wiring, and are widely used in various power supply scenarios such as outdoor substations, municipal power grids, and industrial parks. Currently, most mainstream traditional RMUs on the market adopt a fixed enclosure structure. The internal electrical functional modules, heat dissipation components, and dust removal components are all fixedly installed. The overall structural form, internal space partitioning, and module position angles cannot be dynamically adjusted. They rely solely on the fixed heat dissipation slots and fixed cooling fans pre-installed in the enclosure for passive ventilation and heat dissipation. At the same time, they rely on a simple enclosure sealing structure to achieve basic protection, meeting the basic power operation requirements under normal working conditions.

[0003] Traditional ring main units suffer from core defects in long-term operation, including poor heat dissipation and dust removal performance, and a rigid spatial layout. The internal modules of traditional ring main units are densely and fixedly arranged with narrow gaps and a rigid layout, easily creating numerous ventilation dead zones and dust accumulation blind spots. Airflow within the unit is impeded, and cooling fans can only provide localized, point-to-point cooling, failing to target high-temperature modules. Simultaneously, the internal electrical modules remain stationary, allowing dust to continuously adhere to and accumulate on module surfaces and within gaps. Conventional passive ventilation methods are ineffective in dust removal, and accumulated dust further blocks ventilation gaps, creating a vicious cycle of dust accumulation, air blockage, and heat accumulation. Furthermore, traditional equipment lacks a dynamic spatial adjustment structure; internal functional modules cannot adjust their position and angle according to temperature and humidity conditions, resulting in a severe deficiency in overall intelligent control capabilities, making it unable to adapt to the dynamic operational needs of complex conditions.

[0004] The aforementioned defects in existing technologies directly lead to numerous safety hazards and maintenance problems in power operation, severely impacting the stable operation of the distribution network. Firstly, the inability to dissipate heat from modules in a timely manner, resulting in continuous accumulation of localized high temperatures, accelerates the aging of electrical components and damages insulation layers, significantly increasing the probability of short circuits, overloads, and tripping faults, thus reducing the lifespan of the ring main unit and the stability of power supply. Secondly, long-term accumulation of dust absorbs moisture from the air, easily causing modules to become damp and leak electricity, making them highly susceptible to electrical faults in high humidity and rainy environments, and exhibiting extremely poor adaptability to harsh outdoor environments. Thirdly, traditional ring main units lack adaptive sealing protection structures, and their heat dissipation slots are mostly permanently open, allowing sand, rainwater, and debris to easily penetrate the interior of the unit, further exacerbating equipment damage. Finally, the fixed integrated structure makes equipment maintenance and repair difficult, preventing modular rapid maintenance and visual inspection, resulting in a large workload, low efficiency, and high cost, failing to meet the current requirements of refined, intelligent, and highly stable operation and maintenance for smart grids.

[0005] Therefore, an intelligent protective ring network box was proposed to solve the above problems. Summary of the Invention

[0006] 1. The technical problem to be solved by the present invention

[0007] The purpose of this invention is to propose an intelligent protective ring network box to solve the technical problems of poor heat dissipation and dust removal performance and low level of intelligence in existing ring network boxes.

[0008] 2. Technical Solution To achieve the above objectives, the present invention provides the following technical solution: 1. An intelligent protective ring network box, characterized in that it includes a ring network box body, a protective door is installed on one side of the ring network box body, a multi-dimensional adjustment mechanism and a multi-functional auxiliary mechanism are respectively installed in the middle part of the ring network box body, the multi-dimensional adjustment mechanism is symmetrically arranged on the inner wall of the ring network box body, the multi-dimensional adjustment mechanism is used for spatial control of the multi-functional auxiliary mechanism, the multi-functional auxiliary mechanism is arranged in the middle of the multi-dimensional adjustment mechanism, and the multi-functional auxiliary mechanism is used for automatic dust removal and heat dissipation of the box body.

[0009] Preferably, the multi-dimensional adjustment mechanism includes a track plate, which is slidably installed on the inner wall of the ring network box. A heat dissipation device is installed in the middle of the ring network box, and a dust collection device is installed above the ring network box. A drive device is installed in the middle of the track plate, and a sensory limit plate is fixedly installed on the drive shaft of the drive device.

[0010] Preferably, a push plate is fixedly installed on one side of the sensory impairment limiting plate, and a slip ring is rotatably installed on the push plate. An arc-shaped notch is opened on the side of the sensory impairment limiting plate near the slip ring. A cross-shaped functional block is provided above the sensory impairment limiting plate. The center of the cross-shaped functional block is rotatably installed on the track plate, and an arc-shaped notch is also evenly opened on the cross-shaped functional block.

[0011] Preferably, a guide groove is provided between the arc-shaped notches of the cross-shaped functional block, and the sliding ring on the push plate slides in the guide groove. The arc-shaped notches on the cross-shaped functional block are in contact with the outer arc surface of the notch limiting disk. The middle part of the cross-shaped functional block is fixedly installed on the multi-functional auxiliary mechanism. A collector fan is installed on the outer surface of the cross-shaped functional block, and the outer side of the collector fan is fixedly installed on the inner wall of the track plate by a bracket.

[0012] Preferably, the multifunctional auxiliary mechanism includes a drive shaft, which is fixedly installed in the middle of the cross-shaped functional block. A V-shaped module frame is fixedly installed on the outer circumference of the drive shaft. An airflow groove is formed in the middle of the V-shaped module frame and the drive shaft. The airflow groove is used for heat exchange and cooling of the V-shaped module frame.

[0013] Preferably, a module box is slidably installed in the middle of the V-shaped module frame, a positioning plate is rotatably installed at the end of the drive shaft away from the cross functional block, the positioning plate is fixedly installed on the track plate, a limit groove is opened in the middle of the positioning plate, ventilation holes are evenly opened on the inner side of the limit groove, and a positioning rod is fixedly installed on the side of the module box near the positioning plate, and the positioning rod is slidably installed in the limit groove.

[0014] Furthermore, this solution proposes an intelligent control method for intelligent protective ring network boxes, including the following steps: S1. Normal monitoring and ventilation: The temperature and humidity data inside the ring network box are collected in real time by the temperature and humidity sensors integrated inside the box. Under normal working conditions, the sealing heat dissipation device on the outer wall of the ring network box is opened to keep the heat dissipation slots open. Together with the heat dissipation device, the collector fan and the dust collection device, a normal ventilation and dust removal air duct is formed inside the box to continuously dissipate heat and adsorb floating dust on the electrical modules inside the module box. S2. Abnormal operating condition judgment: The control system compares the sensor data with the preset temperature and humidity thresholds in real time. When the temperature of any module box exceeds the standard or the humidity inside the box is too high, it determines that the equipment is in an abnormal high temperature and high humidity condition and triggers the multi-dimensional adjustment mechanism to start. S3. Precise repositioning adjustment: The drive device in the middle of the track plate drives the corner limiting disk to rotate in one direction. The corner limiting disk drives the sliding ring at the end of the push plate to slide along the guide groove of the cross functional block. When the corner limiting disk rotates one revolution, it drives the cross functional block to complete a precise 90-degree flip through the limiting fit between the arc-shaped corner and the arc-shaped corner of the cross functional block. S4. Targeted heat dissipation and dehumidification: The cross-shaped functional block synchronously drives the drive shaft, V-shaped module frame and abnormal module box to flip and reposition as a whole, rotating the abnormal electrical module to the heat dissipation position that fits the heat dissipation device. The airflow groove between the drive shaft and the V-shaped module frame forms a through-type directional air duct, which, together with the collector fan, concentrates and delivers air to complete targeted and rapid cooling, dehumidification and dust removal operations. S5. Reset to normal operation: After the sensor monitors the internal temperature and humidity data of the enclosure to the preset normal threshold, the control system controls each mechanism to reset, the multi-functional auxiliary mechanism returns to the initial position, and the equipment resumes normal ventilation and heat dissipation operation.

[0015] As a preferred option, a harsh environment adaptive protection and visualized operation and maintenance method is also included, with the following specific steps: When the ring network enclosure is in harsh environments such as heavy rain, sandstorms, and high humidity, the control system shuts down all sealing and heat dissipation devices on the outer wall of the enclosure, blocks all heat dissipation slots, and, together with the protective door, forms a completely sealed protective cavity to prevent external moisture and sand from entering the enclosure. After the harsh environment ends, the sealing and heat dissipation devices are automatically turned on to restore ventilation and dust removal. During equipment inspection, the multi-dimensional adjustment mechanism is slightly rotated and adjusted, and the positioning rod slides along the limit groove of the positioning plate to dynamically extend each group of module boxes to the observation area of ​​the enclosure, realizing visual inspection without disassembly. During equipment maintenance, the entire mechanism can be pulled out directly by pulling the track plate, and the module boxes can be slid and disassembled individually to complete modular rapid maintenance.

[0016] Compared with existing technologies, the intelligent protective ring network box provided by this invention has the following beneficial effects: Compared to traditional fixed ring main units, this invention offers the advantage of dynamic three-dimensional heat dissipation and dust removal, effectively reducing the industry pain points of static dust adhesion and numerous heat dissipation dead zones inherent in existing technologies. Traditional ring main units have fixed internal electrical modules, which easily accumulate dust on module surfaces and in gaps during long-term static operation. Furthermore, the fixed airflow in the ductwork is limited, making it impossible to alleviate dust and heat accumulation problems on their own. This invention employs a multi-dimensional dynamic flipping structure, using a corner-limiting disc and a cross-shaped functional block to achieve controllable 90-degree flipping of the modules, breaking the static dust adhesion conditions. Simultaneously, the modular staggered structure continuously maintains uniform ventilation gaps, eliminating ventilation blind spots and heat dissipation dead zones in traditional equipment. Combined with the dust collection device and the collector fan, it achieves active circulating dust removal and heat dissipation, fundamentally preventing the vicious cycle of dust accumulation, air blockage, and heat aging.

[0017] This invention features intelligent targeted temperature and humidity control, overcoming the shortcomings of traditional ring main unit (RMU) cooling systems, which rely on a single cooling mode and cannot provide targeted cooling and dehumidification. Traditional RMUs depend solely on fixed fans for passive cooling across the entire area, failing to identify localized high-temperature and high-humidity areas, resulting in high energy consumption, low efficiency, and frequent localized overheating failures. This solution utilizes internal temperature and humidity sensors for real-time, comprehensive monitoring, accurately locating abnormal module areas. A multi-dimensional adjustment mechanism automatically flips high-temperature and high-humidity modules to their designated positions aligned with the cooling device. Combined with a through-flow channel between the drive shaft and the V-shaped module frame, this forms a directional airflow, achieving one-to-one targeted and rapid cooling and dehumidification. This significantly improves the accuracy and response speed of temperature and humidity control, effectively preventing electrical modules from overheating and aging, and avoiding short circuits due to moisture, thus significantly enhancing equipment operational stability and lifespan.

[0018] This invention features an adaptive sealing and protection function, effectively overcoming the technical shortcomings of traditional ring main units, such as poor environmental adaptability and weak protection capabilities. Traditional ring main units typically have fixed, normally open heat dissipation troughs, unable to switch protection modes according to the external environment. Under harsh conditions such as heavy rain, sandstorms, and high humidity, moisture, dust, and debris can easily penetrate the unit, accelerating corrosion and damage to internal components, resulting in poor outdoor operational safety. This solution integrates a controllable sealing and heat dissipation device on the outer wall of the ring main unit. It can adaptively switch between ventilation and sealing modes according to operating conditions and environmental requirements. In harsh environments, the heat dissipation troughs can be completely sealed, forming a fully enclosed protective cavity with a protective door, completely blocking the intrusion of external pollutants. Under normal operating conditions, ventilation and heat dissipation are activated, addressing both ventilation and sealing protection needs, greatly improving the equipment's adaptability to complex environments.

[0019] This invention employs a high-precision limit linkage structure, effectively solving the problems of poor positioning accuracy, easy jamming, and insufficient stability in traditional adjustable ring main units. Existing adjustable ring main units often use simple shaft adjustment, lacking a precise limit structure for flipping and positioning. Long-term operation easily leads to malfunctions such as angle deviation, module shaking, and mechanism jamming, resulting in poor adjustment reliability. This solution uses a notched corner limit plate and a cross-shaped functional block with an arc-shaped notched corner for limiting, combined with a push plate slip ring and guide groove sliding guidance, and a positioning plate with a limit groove and positioning rod for auxiliary positioning, forming a double limit guiding structure. This achieves the effect of limiting during rotation and precise positioning during repositioning. The mechanism has high linkage accuracy and strong stability, effectively reducing the probability of failure during long-term operation and improving the durability of the equipment.

[0020] This invention features a modular, pull-out, and convenient operation and maintenance structure, completely overcoming the drawbacks of traditional ring main units (RMUs) that are cumbersome to assemble and disassemble, difficult to inspect, and have high maintenance costs. Traditional RMUs are fixed structures with difficult internal module assembly and disassembly, making visual inspection impossible. Fault diagnosis and module replacement require complete disassembly, resulting in a large workload and extremely low efficiency. This solution integrates a multi-dimensional adjustment mechanism onto a sliding track plate, enabling pull-out maintenance. Simultaneously, the module boxes on the V-shaped module frame adopt an independent sliding assembly and disassembly structure, supporting individual module maintenance. Furthermore, modules can be dynamically repositioned to extend into the observation area, achieving non-disassembly visual inspection, significantly simplifying the operation and maintenance process, reducing maintenance difficulty and labor costs, and adapting to the refined and efficient operation and maintenance needs of smart grids.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] For an example, please refer to... Figures 1 to 9 As shown: To address the problems mentioned in the technical solutions, this application discloses an intelligent protective ring main unit, belonging to the technical field of power ring main unit equipment. The equipment includes a ring main unit 1, with a protective door 11 hinged to one side for opening, closing, and sealing, providing basic protection for the internal electrical modules. A multi-dimensional adjustment mechanism 2 and a multi-functional auxiliary mechanism 3 are respectively installed in the central area inside the ring main unit 1. The multi-dimensional adjustment mechanism 2 is symmetrically arranged and fixed to the left and right inner walls of the ring main unit 1, mainly used to achieve precise multi-dimensional spatial position and angle control of the multi-functional auxiliary mechanism 3. The multi-functional auxiliary mechanism 3 is mounted in the middle of the multi-dimensional adjustment mechanism 2, relying on the dynamic adjustment capability of the multi-dimensional adjustment mechanism 2 to achieve automated dust removal, intelligent heat dissipation, dehumidification, and ventilation within the unit, solving the technical drawbacks of traditional ring main units' single and fixed heat dissipation and dust removal methods.

[0026] Specifically, the multi-dimensional adjustment mechanism 2 includes track plates 21 symmetrically slidably mounted on the inner wall of the ring mesh housing 1. The track plates 21 can be adjusted slightly forward and backward and left and right along the inner wall of the housing, providing a structural basis for internal module maintenance and space expansion. A heat dissipation device 22 is fixedly mounted between multiple sets of track plates 21, and a dust collection device 23 is fixedly installed on the top of the ring mesh housing 1. The two work together to achieve coordinated heat dissipation and dust removal inside the housing. A drive device is embedded and fixed in the middle of the track plate 21, and a notched corner limiting disc 24 is fixedly mounted on the output shaft end of the drive device, providing power support for the mechanism's angle rotation and precise positioning.

[0027] This solution uses a drive device to rotate the notched corner limiting plate 24 one full rotation in one direction, which can precisely drive the matching cross-shaped functional block 26 to complete a 90-degree precise rotation. This enables the angle switching and workstation adjustment of the various functional modules of the multi-functional auxiliary mechanism 3, completing the dynamic transformation of the internal functional space of the enclosure. Compared with the traditional fixed ring network enclosure structure, this three-dimensional modular design has multiple technical advantages: First, it completely solves the problem of static dust adhesion and accumulation on the surface of electrical modules of traditional equipment, which is difficult to clean, by relying on the dynamic rotation structure to destroy the dust adhesion conditions; second, it greatly improves the integration of the internal space of the enclosure, integrating multiple functions such as heat dissipation, dust removal, adjustment, and protection within the limited enclosure space, resulting in a higher degree of equipment integration; third, uniform ventilation gaps are reserved between the modular structures, eliminating the heat dissipation dead corners and ventilation blind spots inside the traditional enclosure, and comprehensively improving the overall heat dissipation and ventilation performance.

[0028] Meanwhile, the ring network enclosure 1 is equipped with integrated temperature and humidity sensors, which can collect real-time temperature and humidity data of the internal environment 24 hours a day. Relying on the built-in control system, it coordinates and controls the multi-dimensional adjustment mechanism 2 to complete precise spatial adjustment and module repositioning operations. Furthermore, multiple sets of sealing and heat dissipation devices are evenly distributed on the outer wall of the ring network enclosure 1. The opening and closing states of each heat dissipation slot can be independently controlled, allowing for adaptive switching between enclosure sealing and ventilation modes based on the external environment and internal operating conditions. In severe environments such as heavy rain, sandstorms, and high humidity, the heat dissipation slots can be completely closed, achieving overall enclosure sealing and protection, preventing moisture, dust, and debris from entering the enclosure, and ensuring stable operation of the electrical modules.

[0029] To further refine the mechanism structure, a push plate 25 is fixedly welded to the outer wall of the notched corner limiting disk 24, and a wear-resistant slip ring is rotatably assembled at the end of the push plate 25; an arc-shaped notched corner structure is provided on the side of the notched corner limiting disk 24 near the slip ring, and a cross-shaped functional block 26 is matched and arranged directly above the notched corner limiting disk 24. The center position of the cross-shaped functional block 26 is rotatably assembled on the inner side of the track plate 21, and the four ends of the cross-shaped functional block 26 are evenly provided with arc-shaped notches that match the notched corner limiting disk 24.

[0030] The technical advantages of this limiting structure are as follows: by matching the notched corner limiting plate 24 with the arc-shaped notched corner of the cross-shaped functional block 26, precise limiting of the cross-shaped functional block 26 during the flipping process can be achieved, eliminating angle deviation and shaking problems; at the same time, relying on the sliding cooperation between the slip ring at the end of the push plate 25 and the guide groove 27, the cross-shaped functional block 26 can be precisely driven to complete the rotation of the set angle, achieving a stable operation effect of "rotation is limiting, and repositioning is positioning", effectively improving the adjustment accuracy and operation stability of the mechanism, and avoiding misalignment and jamming failures during long-term operation.

[0031] In this design, an arc-shaped guide groove 27 is formed between two adjacent sets of arc-shaped notches in the cross-shaped functional block 26. The sliding ring of the push plate 25 is slidably embedded in the guide groove 27, forming a closed-loop sliding guide structure. The inner wall of the arc-shaped notch of the cross-shaped functional block 26 is tightly fitted with the outer arc surface of the notch limiting plate 24, further improving the limiting fit. The center of the cross-shaped functional block 26 is fixedly connected to the multi-functional auxiliary mechanism 3. A collector fan 28 is assembled on the outside of the cross-shaped functional block 26. The collector fan 28 is installed on the inner wall of the track plate 21 through a fixed bracket. The collector fan 28 can be synchronously moved with the cross-shaped functional block 26 to specifically gather airflow, enhance local heat dissipation and dust removal effects, and solve the problems of limited heat dissipation range and uneven dust removal of traditional fixed fans.

[0032] The multi-dimensional adjustment mechanism 2 is integrated into the inner side of the track plate 21, featuring a compact, integrated design that is easy to assemble and disassemble. Workers can directly pull the track plate 21 for pull-out maintenance of the entire mechanism without disassembling the entire housing structure, significantly reducing the difficulty of later maintenance, repair, and replacement, improving operational efficiency, and lowering maintenance costs. Simultaneously, multiple track plates 21 share a single heat dissipation device 22, achieving coordinated heat dissipation across multiple modules of a single device, resulting in higher equipment utilization and lower energy consumption.

[0033] The intelligent control logic of the supporting sensors has significant technical advantages: the temperature sensor monitors the operating temperature of the electrical modules inside each module box 34 in real time. When the monitored temperature exceeds the preset safety threshold, the control system automatically triggers the operation of the multi-dimensional adjustment mechanism 2, which precisely flips the high-temperature module to the heat dissipation position that fits the heat dissipation device 22, so as to achieve targeted and rapid cooling. At the same time, it works with the airflow structure to complete the module dehumidification operation, quickly eliminate the hidden dangers of high temperature and high humidity conditions, effectively avoid the electrical modules from overheating and aging, and short circuits due to moisture, and greatly improve the safety and service life of the equipment.

[0034] Specifically, the multifunctional auxiliary mechanism 3 includes a drive shaft 31, the top of which is fixedly mounted to the center of the cross-shaped functional block 26, and can rotate synchronously with the cross-shaped functional block 26. A V-shaped module frame 32 is uniformly fixedly mounted on the outer circumference of the drive shaft 31. The area where the V-shaped module frame 32 connects to the drive shaft 31 is uniformly provided with through-flow airflow slots 33. The airflow slots 33 form a through-flow ventilation and heat dissipation channel, continuously providing commutation, heat dissipation, dehumidification, and ventilation conditions for the electrical modules on the V-shaped module frame 32, preventing heat accumulation and moisture retention, and ensuring continuous and stable operation of the modules.

[0035] A detachable module box 34 is slidably mounted on the inner side of the V-shaped module frame 32, facilitating the disassembly, replacement, and individual maintenance of electrical modules. A positioning disk 35 is rotatably mounted on the bottom end of the drive shaft 31 away from the cross-shaped functional block 26. The positioning disk 35 is fixedly embedded inside the track plate 21 to maintain structural stability. An annular limiting groove 36 is formed in the center of the positioning disk 35, and multiple sets of ventilation holes are evenly distributed inside the limiting groove 36 to ensure bottom ventilation and heat dissipation while achieving limiting positioning. A positioning rod 37 is fixedly mounted on the side of the module box 34 near the positioning disk 35, and the positioning rod 37 is slidably embedded inside the limiting groove 36.

[0036] The technical advantages of this positioning and matching structure are as follows: When the multi-dimensional adjustment mechanism 2 drives the transmission shaft 31 to rotate and change position with the module box 34, the sliding limit cooperation between the limiting groove 36 and the positioning rod 37 can accurately limit the rotation trajectory and final position of the module box 34, ensuring the repositioning accuracy. At the same time, it can drive each group of module boxes 34 to dynamically approach the observation window of the enclosure, realizing the dynamic extension and display of electrical modules. The staff can intuitively observe the operating status of each module without disassembling the structure, realizing modular dynamic adjustment and visualized operation and maintenance, greatly improving the convenience of equipment inspection and adapting to the needs of refined operation and maintenance.

[0037] Example 2: Based on Embodiment 1, but with some differences, the present invention provides an intelligent protective ring network box with reference to specific examples and accompanying drawings. The specific details are as follows: First, the ring network enclosure 1 is fixedly installed. A protective door 11 is hinged and installed on one side of the ring network enclosure 1. The protective door 11 enables the opening and closing of the enclosure and provides a sealed protection for the foundation, providing a closed installation space for the internal mechanisms. Then, two sets of multi-dimensional adjustment mechanisms 2 are symmetrically installed on the left and right inner walls of the ring network enclosure 1, so that the track plate 21 of the multi-dimensional adjustment mechanism 2 slides against the inner wall of the enclosure, ensuring that the track plate 21 can flexibly slide back and forth and left and right in small increments.

[0038] A heat dissipation device 22 is fixedly assembled between multiple symmetrically arranged track plates 21, while a dust collection device 23 is fixedly installed on the top of the ring network box 1, forming a heat dissipation and dust removal basic assembly. A drive device is embedded and fixed in the middle of each track plate 21, and the output shaft of the drive device is fixedly connected to the corner limiting plate 24, completing the assembly of the power drive assembly. Finally, the multi-functional auxiliary mechanism 3 is mounted as a whole in the middle of the two sets of multi-dimensional adjustment mechanisms 2, so that the top of the multi-functional auxiliary mechanism 3 is fixedly connected to the cross function block 26, and the bottom end is rotatably engaged with the positioning plate 35, completing the assembly of the whole machine structure.

[0039] After the equipment is put into normal power operation, the temperature and humidity sensors integrated inside the ring network box 1 continuously collect environmental data inside the box for 24 hours, monitor the operating temperature of the electrical modules inside each module box 34 and the air humidity inside the box in real time, and transmit the monitoring data to the built-in control system of the equipment in real time, providing data support for subsequent intelligent adjustment.

[0040] Under normal operating conditions, the sealed heat dissipation device on the outer wall of the ring main unit 1 is always open, and each heat dissipation slot is kept ventilated, forming a normalized ventilation and heat dissipation airflow in conjunction with the internal heat dissipation device 22 and the collector fan 28. At the same time, the dust collection device 23 continuously adsorbs floating dust inside the unit, preventing dust from being statically attached to the surface of the electrical modules for a long time, thus solving the problem of difficult-to-clean dust accumulation in traditional ring main units. At this time, the multi-dimensional adjustment mechanism 2 and the multi-functional auxiliary mechanism 3 maintain fixed operation, and the ventilation gaps reserved between each module continue to ventilate, eliminating heat dissipation dead zones and ensuring the stable operation of the equipment under normal conditions.

[0041] When the sensor detects that the temperature of an electrical module inside a module box 34 exceeds a preset safety threshold, or that the humidity inside the box is too high, the control system immediately triggers the multi-dimensional adjustment mechanism 2 to start working. The drive device in the middle of the track plate 21 starts, driving the corner limiting disk 24 to rotate in one direction. During the rotation of the corner limiting disk 24, the wear-resistant slip ring at the end is driven to slide inside the guide groove 27 of the cross functional block 26 through the push plate 25 fixed on the outside.

[0042] When the notched corner limiting plate 24 rotates one revolution, the arc-shaped notch and the arc-shaped notch of the cross-shaped functional block 26 are fitted together to precisely drive the cross-shaped functional block 26 to complete a 90-degree flip. The cross-shaped functional block 26 simultaneously drives the centrally fixed drive shaft 31, V-shaped module frame 32 and corresponding module box 34 to flip and reposition as a whole, so as to precisely rotate the electrical module corresponding to high temperature and high humidity to the dedicated heat dissipation station that fits the heat dissipation device 22.

[0043] After the repositioning is completed, the heat dissipation device 22 starts high-intensity heat dissipation, forming a directional ventilation channel with the through airflow groove 33 between the drive shaft 31 and the V-shaped module frame 32. This quickly removes the accumulated heat and moisture inside the module box 34, achieving targeted and rapid cooling and dehumidification. At the same time, the collector fan 28, which repositions synchronously with the cross-shaped functional block 26, gathers the airflow, enhancing the local heat dissipation and dust removal effect, and further improving the temperature and humidity regulation efficiency. Once the sensor monitoring data returns to the normal threshold, the mechanism resets and returns to normal operating status.

[0044] Throughout the entire process of flipping and repositioning the cross-shaped functional block 26, the adjustment accuracy is ensured by a dual limiting structure: First, the outer arc surface of the notched corner limiting plate 24 always fits against the arc-shaped notched corner of the cross-shaped functional block 26 to achieve angle limiting and prevent angle deviation and mechanism shaking during flipping; Second, the slip ring at the end of the push plate 25 always slides in a closed loop inside the guide groove 27 to limit the rotation trajectory and achieve the operating effect of "rotation is limiting and repositioning is positioning", effectively avoiding misalignment and jamming failures during long-term operation of the mechanism.

[0045] Meanwhile, the positioning plate 35 at the bottom of the drive shaft 31 remains fixed, and the positioning rod 37 on one side of the module box 34 is always slidably embedded in the limiting groove 36 of the positioning plate 35, further limiting the rotation trajectory and final position of the module box 34, ensuring consistent positioning accuracy each time. Furthermore, the ventilation holes arranged inside the limiting groove 36 provide continuous ventilation, preventing the limiting structure from obstructing the airflow and ensuring continuous heat dissipation and dust removal.

[0046] During equipment inspection, the multi-dimensional adjustment mechanism 2 can be rotated slightly to move each group of module boxes 34 to move dynamically closer to the observation area of ​​the ring network box 1 in sequence, so that the internal electrical modules can be dynamically extended and displayed. Staff can intuitively observe the operating status of each module without disassembling any structure and complete the visual inspection operation.

[0047] When the equipment is in a particularly harsh environment such as heavy rain, sandstorms, or high humidity, the control system shuts down all sealing and heat dissipation devices on the outer wall of the ring network box 1 and blocks all heat dissipation slots based on external environmental sensing data or manual control commands, so that the ring network box 1 forms a completely closed protective cavity.

[0048] Combined with the sealing effect of the protective door 11, it completely prevents external moisture, dust, and debris from entering the cabinet, avoiding short circuits and damage to internal electrical modules due to moisture and dust accumulation. After the harsh environment ends, the control system automatically activates the sealing and heat dissipation device, restoring the cabinet's ventilation, heat dissipation, and dust removal operation modes, achieving adaptive sealing protection in harsh environments.

[0049] When the equipment needs to be inspected, modules replaced, or fault repaired, the staff only need to open the protective door 11 and pull the track plate 21 to pull out the entire component integrating the multi-dimensional adjustment mechanism 2 and the multi-functional auxiliary mechanism 3 from the ring network box 1, so as to realize the pull-out overall maintenance.

[0050] Meanwhile, the module box 34 inside the V-shaped module frame 32 adopts a sliding and detachable structure, allowing individual module boxes 34 to be pulled out separately for the inspection and replacement of a single electrical module without disassembling the entire machine structure. After inspection and maintenance, the track plate 21 is pushed back to its original position, and the positioning rod 37 and the limiting groove 36 automatically align and engage, allowing the mechanism to resume normal operation. This significantly simplifies the maintenance process and reduces the difficulty and cost of maintenance.

7. A method for intelligent control of an intelligent protective ring main unit, applicable to the intelligent protective ring main unit as described in any one of claims 1-6, characterized in that, Includes the following steps: S1. Normal monitoring and ventilation: The temperature and humidity data inside the ring network box (1) are collected in real time by the temperature sensor and humidity sensor integrated inside the box. Under normal working conditions, the sealing heat dissipation device on the outer wall of the ring network box (1) is turned on to keep the heat dissipation slot open. Together with the heat dissipation device (22), the collector fan (28) and the dust collection device (23), a normal ventilation and dust removal air duct is formed inside the box to continuously dissipate heat and adsorb floating dust inside the module box (34). S2, abnormal working condition judgment: The control system compares the sensor data with the preset temperature and humidity thresholds in real time. When the temperature of any module box (34) exceeds the standard or the humidity inside the box is too high, it is determined that the equipment is in an abnormal working condition of high temperature and high humidity, and the multi-dimensional adjustment mechanism (2) is triggered to start. S3, Precise repositioning adjustment: The drive device in the middle of the track plate (21) drives the corner limiting disk (24) to rotate in one direction. The corner limiting disk (24) drives the end slip ring of the push plate (25) to slide along the guide groove (27) of the cross function block (26). When the corner limiting disk (24) rotates one revolution, it drives the cross function block (26) to complete a precise 90-degree flip through the limiting fit between the arc-shaped corner and the arc-shaped corner of the cross function block (26). S4, Directional heat dissipation and dehumidification: The cross-shaped functional block (26) synchronously drives the drive shaft (31), V-shaped module frame (32) and abnormal module box (34) to flip and change position as a whole, rotating the abnormal electrical module to the heat dissipation position that fits the heat dissipation device (22). The airflow groove (33) between the drive shaft (31) and the V-shaped module frame (32) forms a through directional air duct, which, together with the collector fan (28), concentrates and delivers air to complete targeted rapid cooling, dehumidification and dust removal operations. S5. Reset to normal operation: After the sensor monitors the temperature and humidity data inside the box and restores to the preset normal threshold, the control system controls each mechanism to reset, the multi-functional auxiliary mechanism (3) returns to the initial position, and the equipment resumes normal ventilation and heat dissipation operation.

8. The intelligent control method for an intelligent protective ring network box according to claim 7, characterized in that, It also includes adaptive protection and visualized operation and maintenance methods for harsh environments, with the following specific steps: When the ring network box (1) is in a harsh environment of heavy rain, sandstorm, and high humidity, the control system shuts down all the sealing and heat dissipation devices on the outer wall of the box and blocks all the heat dissipation slots. With the help of the protective door (11), the ring network box (1) forms a completely closed protective cavity to block external water vapor and sand from entering the box. After the harsh environment ends, the sealing and heat dissipation devices are automatically turned on to restore the ventilation and dust removal conditions. During equipment inspection, the multi-dimensional adjustment mechanism (2) is rotated slightly and adjusted. With the help of the positioning rod (37) sliding along the limit groove (36) of the positioning plate (35), the module boxes (34) are dynamically extended to the box observation area to achieve visual inspection without disassembly. During equipment maintenance, the track plate (21) can be pulled directly to remove the whole mechanism. At the same time, the module boxes (34) can be slid and disassembled separately to complete modular rapid maintenance.
