Description

Technical Field

[0001] This utility model belongs to the field of switchgear technology, specifically relating to an intelligent switchgear operation control device based on multi-feature information monitoring. Background Technology

[0002] In rural power grid architecture, switchgear, as a critical power distribution node, is often installed outdoors on the exterior wall. This type of installation faces complex environmental disturbances: First, temperature and humidity fluctuate significantly. In summer afternoons, the internal temperature of the cabinet can rise above 40°C, while during the rainy season, the relative humidity often remains above 90%, which can easily lead to the degradation of the insulation performance of electrical components. Second, the intrusion of dust, corrosive gases (such as ammonia released from agricultural production), insects, and small rodents in the atmosphere can accelerate contact oxidation and line damage. Third, rural areas have a large maintenance radius and low response time. Traditional switchgear lacks proactive state perception capabilities and relies solely on passive protection structures, making it difficult to detect potential risks such as internal overheating and localized fires in real time.

[0003] Meanwhile, the operation and management of this type of equipment faces multiple challenges: on the one hand, unauthorized personnel's illegal opening and electricity theft are difficult to trace, easily leading to inaccurate electricity metering and equipment damage; on the other hand, the operational standards of maintenance personnel lack effective supervision, and the efficiency of emergency response to sudden failures is limited by on-site conditions. Traditional switchgear, lacking a multi-parameter linkage control mechanism, has significant shortcomings in environmental adaptability, safety protection, and intelligent management, resulting in a shortened mean time between failures (MTBF) and high maintenance costs, thus hindering the improvement of rural power grid reliability. Utility Model Content

[0004] To address the problems and shortcomings of the existing technology, this utility model provides an intelligent switchgear operation control device based on multi-feature information monitoring, which realizes intelligent monitoring and control of multi-feature information of the switchgear, improves operational safety and reliability, adapts to the rural exterior wall installation environment, and reduces failure and maintenance costs.

[0005] This utility model is achieved through the following technical solution:

[0006] An intelligent switchgear operation control device based on multi-feature information monitoring is characterized by comprising a cabinet and a detection device. Electrical components are installed inside the cabinet, and a cabinet door is provided on one side of the cabinet. The detection device includes a control device installed inside the cabinet and temperature sensors, humidity sensors, smoke sensors, and pressure sensors connected to the control device. The opening and closing of the cabinet door triggers the pressure sensors. A camera device, a fire extinguishing device, a cooling fan, and a rainproof device are also installed on the cabinet and connected to the control device. The rainproof device includes a U-shaped fixing frame, a rainproof plate installed inside the U-shaped fixing frame, and a motor that drives the rainproof plate to move vertically.

[0007] By integrating the cabinet with detection devices, temperature, humidity, smoke, and pressure sensors are linked with the control unit. Combined with cameras, fire suppression systems, cooling fans, and rain protection devices, this creates an integrated architecture for multi-feature information collaborative monitoring and control. This design breaks through the traditional single-protection mode of switchgear, achieving comprehensive perception and intelligent response to equipment operating status, environmental parameters, and operational behaviors, thereby improving the equipment's adaptability and safety redundancy in complex rural environments from the source.

[0008] Furthermore, the U-shaped fixing frame opens downwards, and a vertically arranged T-shaped groove is formed on the inner side of the U-shaped fixing frame. T-shaped sliders that mate with the T-shaped groove are located on both sides of the rain shield. This mating structure of the T-shaped groove and T-shaped sliders provides high-precision guiding constraints for the rain shield, effectively eliminating the risk of lateral displacement during vertical movement. This design ensures that the rain shield maintains stability of its movement trajectory under the influence of external forces such as wind and rain, guaranteeing alignment with the cooling fan when in the shielding state and avoiding the potential for rainwater leakage due to mechanical shaking.

[0009] Furthermore, a lead screw and a motor driving the lead screw are vertically installed in the middle of the U-shaped fixing frame. A threaded block that mates with the lead screw is fixed inside the rain shield. The rain shield has a covered state and an open state. When the rain shield is in the covered state, the rain shield and the cooling fan are on the same horizontal plane. The rain shield is driven by a lead screw-threaded block transmission mechanism. Utilizing the self-locking property and displacement precision of the lead screw transmission, reliable switching between the two working states of the rain shield is achieved: in the covered state, the rain shield is precisely aligned with the horizontal plane of the cooling fan, forming a rain barrier; in the open state, it completely avoids the fan's air intake path, ensuring that the heat dissipation efficiency is not affected. The motor drive method solves the problem of lag in manual adjustment and improves the response speed to sudden rainfall.

[0010] Furthermore, the top of the U-shaped mounting bracket has a slot for accommodating the rain shield. A magnetic component is installed within the slot, attracting the top of the rain shield. This slot design provides storage space for the rain shield, allowing its top to be concealed within the top of the U-shaped mounting bracket when the rain shield is in its sheltered state, reducing the erosion of the cabinet's interior by external rainwater. The magnetic component further enhances the rain shield's stability through its attraction, preventing vibration and noise under conditions such as strong winds, and extending the equipment's lifespan.

[0011] Furthermore, a solar panel is installed on the top of the cabinet, and an energy storage power supply is installed inside the cabinet to connect the solar panel and electrical components. This combination of solar panels and energy storage power supply constructs a clean energy power supply system independent of mains power. This not only reduces reliance on traditional electricity but also ensures the operation of core components such as sensors and control devices during power outages, guaranteeing uninterrupted monitoring and enhancing the equipment's continuous operational capability.

[0012] Furthermore, a light is installed at the bottom of the cabinet, which is electrically connected to the energy storage power supply. A photosensitive switch is also installed on the light. Linking the light to the photosensitive switch enables adaptive control of light intensity. It automatically turns on when the ambient illuminance is below a threshold, providing localized lighting for nighttime maintenance; it automatically turns off when there is sufficient light, avoiding energy waste. This design optimizes the convenience of outdoor operations in rural areas while ensuring the independence of the lighting function through the energy storage power supply.

[0013] Furthermore, the fire extinguishing device is a dry powder fire extinguishing device, with its nozzles directed towards the densely packed electrical components within the cabinet. By directionally positioning the nozzles in this area, the electrical insulation and rapid asphyxiation properties of the dry powder extinguishing agent allow for precise application to the core risk area in the early stages of a fire. Compared to an all-space spray system, this design reduces the amount of extinguishing agent used while minimizing secondary damage to components in non-faulty areas, thus improving fire extinguishing efficiency and equipment protection accuracy.

[0014] Furthermore, the camera device includes a high-definition camera and a storage module, which is connected to the monitoring terminal via a wireless communication module. The high-definition camera and the wirelessly transmitted storage module enable visual recording and remote traceability of the operation process. High-definition image quality ensures that operational details are identifiable, and the dual-path design of local backup in the storage module and real-time upload from the monitoring terminal effectively prevents the risk of data loss, providing a complete data chain for evidence collection of violations and tracking of illegal intrusions, thus strengthening the management standardization of rural power distribution facilities.

[0015] Furthermore, the control device controls the speed of the cooling fan via a PWM signal, while a temperature sensor monitors the temperature inside the cabinet in real time and transmits this information to the control device. By using PWM signals to control the cooling fan speed, combined with real-time feedback from the temperature sensor, a closed-loop temperature control system is constructed. By dynamically adjusting the fan output power, the fan speed is reduced or even stopped to save energy when the cabinet temperature is below a threshold, and the heat dissipation capacity is linearly increased when the temperature rises, achieving a dynamic balance between heat dissipation efficiency and energy consumption, thus avoiding the energy waste problem of traditional fixed-speed fans.

[0016] Furthermore, a pressure sensor is installed on the side of the cabinet near the door. When the door is opened, the pressure sensor is triggered and sends a signal to the control device. Installing the pressure sensor near the door utilizes the mechanical contact trigger signal during door opening and closing to ensure an immediate response to door opening actions. This installation position is more effective at detecting door displacement compared to the latch, effectively avoiding trigger delays caused by lock wear, improving the timeliness of the camera device's activation, and ensuring the integrity of recorded user actions.

[0017] The beneficial effects of this utility model are:

[0018] 1. Significantly improved environmental adaptability: Addressing issues such as drastic fluctuations in outdoor temperature and humidity in rural areas and rain intrusion, the system achieves precise temperature control inside the cabinet through the linkage of a temperature sensor and a PWM speed-regulating fan, preventing electrical components from aging due to high temperatures; the humidity sensor triggers the automatic opening and closing of the rainproof device, which, combined with the stable structure of the T-shaped slide and the screw drive, can prevent rainwater from entering through the fan in rainy weather without affecting the heat dissipation efficiency in sunny weather, effectively solving the contradiction between waterproofing and heat dissipation in outdoor equipment.

[0019] 2. Comprehensive Enhancement of Safety Protection System: Constructing a Closed-Loop Protection Mechanism of "Monitoring-Early Warning-Response": Smoke sensors capture potential fire hazards in real time, and dry powder fire extinguishers target areas with dense electrical appliances to quickly suppress initial fires; the press sensor is linked with a high-definition camera device, and the opening of the cabinet door triggers video recording, storage, and remote transmission, enabling traceability of operational behavior. This not only prevents unauthorized electricity theft and damage but also standardizes the operating procedures of maintenance personnel, significantly reducing the risk of safety accidents.

[0020] 3. Optimized Energy Supply and Maintenance Convenience: The combination of solar panels and energy storage power sources eliminates reliance on mains power, making it particularly suitable for scenarios with insufficient rural power grid stability and reducing energy consumption. The photosensitive control design of the bottom lighting in the cabinet allows it to automatically turn on when there is insufficient sunlight. The fully automated operation of the system reduces the frequency of manual inspections, and combined with data interaction from remote monitoring terminals, it significantly reduces maintenance costs and response time in rural areas.

[0021] 4. Increased equipment reliability and lifespan: The structured design of each component (such as the magnetic fixing of the rain shield and the T-shaped slider guide) improves the stability of mechanical movements; real-time monitoring and predictive control by multiple sensors avoid insulation failure or short circuit faults caused by abnormal temperature and humidity or foreign object intrusion of electrical components, greatly extending the mean time between failures of the equipment and ensuring the continuity of power supply to rural power grids.

[0022] In summary, this invention achieves "autonomous sensing, automatic handling, and remote monitoring" of switchgear in complex outdoor environments through deep collaboration of multi-feature information fusion perception and intelligent execution, comprehensively improving the safety, economy, and reliability of equipment operation, and providing a practical solution for the intelligent upgrading of rural power grids.

[0034] like Figures 1 to 5The present invention discloses an intelligent switchgear operation control device 2 based on multi-feature information monitoring, which aims to achieve comprehensive monitoring and automated control of switchgear installed on rural exterior walls by integrating multiple types of sensors and intelligent control components.

[0035] The core components of the device include a cabinet 1 and a detection device. Electrical components 11 are installed inside the cabinet 1, and a cabinet door 12 is located on one side. The detection device, centered on a control device 2, is connected to a temperature sensor, a humidity sensor, a smoke sensor, and a pressure sensor 3 (installed on the side of the cabinet 1 near the cabinet door 12, triggered when the door 12 is opened or closed). The cabinet 1 is also equipped with a camera device 4 (including a high-definition camera and a storage module, the storage module being connected to a monitoring terminal via a wireless communication module), a dry powder fire extinguishing device 5 (the nozzle is directed towards the area densely populated with electrical components 11), a cooling fan 6 (its speed is adjusted by the control device 2 via a PWM signal), and a rainproof device 7.

[0036] The rain shield device 7 has the following specific structure: a U-shaped fixing frame 71 with its opening facing downwards, and a vertical T-shaped sliding groove 711 on its inner side; T-shaped sliders 721 that cooperate on both sides of the rain shield 72; a lead screw 74 and a drive motor are vertically installed in the middle of the fixing frame; a threaded block 722 that cooperates with the lead screw 74 is fixed to the inner side of the rain shield 72, allowing the rain shield 72 to switch between a covered state (at the same level as the cooling fan 6) and an open state; a slot 712 for accommodating the rain shield 72 is provided at the top of the fixing frame, and a magnetic component 75 is provided inside to attract the top of the rain shield 72. In addition, a solar panel 8 is installed on the top of the cabinet 1, and an energy storage power supply connecting the solar panel 8 and the electrical components 11 is located inside the cabinet; a lighting lamp 9 connected to the energy storage power supply is installed at the bottom of the cabinet 1, and a photosensitive switch is installed on it.

[0037] During operation, control device 2 receives signals from various sensors: the temperature sensor transmits temperature data in real time, and control device 2 adjusts the fan speed via PWM signals; the humidity sensor detects a sudden increase in humidity (such as during rain), controlling the motor of rain shield device 7 to drive the lead screw 74, causing the rain shield 72 to move upwards along the T-shaped slide 711 to the slot 712 where it is attracted by the magnetic component 75, forming a shield to prevent rainwater from entering. After the rain stops, the rain shield 72 moves downwards to avoid obstructing the airflow of the cooling fan 6; the smoke sensor detects a fire and triggers the dry powder fire extinguishing device 5 to spray directional fire extinguishing; when the cabinet door 12 is opened, the press sensor 3 is triggered, and control device 2 activates the camera device 4, recording and storing the high-definition video in the storage module, and uploading it to the monitoring terminal via the wireless communication module. The solar panel 8 converts light energy into electrical energy and stores it in the energy storage power supply to power various components; the bottom lighting 9 of the cabinet 1 is controlled by a photosensitive switch, automatically turning on when there is insufficient light, improving operational convenience and the brightness around the cabinet 1.

[0038] In one embodiment, the temperature and humidity control and the rain shield 7 work together, fully integrating various technical features. The cabinet 1 is made of cold-rolled steel plate, and the cabinet door 12 is connected to the cabinet 1 via hinges. The control device 2 uses a microcontroller, with a temperature sensor installed in the middle of the cabinet and a humidity sensor located on the inner top of the cabinet 1; both have high detection accuracy. The U-shaped fixing frame 71 of the rain shield 7 is made of aluminum alloy, with the opening facing downwards. The inner T-shaped sliding groove 711 precisely matches the T-shaped sliders 721 on both sides of the rain shield 72. The screw 74 in the middle of the fixing frame is driven by a stepper motor, and the threaded block 722 on the inner side of the rain shield 72 meshes with the screw 74 for transmission, which can stably switch between the blocking and open states. The slot 712 at the top of the fixing frame contains a magnetic component 75, which can securely attract the top of the rain shield 72.

[0039] The cooling fan 6 is an axial fan. The control device 2 adjusts the speed through a PWM signal and automatically adjusts it according to the temperature sensor detection results: it runs at high speed when the temperature is high, at medium speed when the temperature is medium, and stops when the temperature is low.

[0040] The pressure sensor 3 is installed on the side of the cabinet 1 near the cabinet door 12. When the cabinet door 12 is opened, a signal is triggered, and the control device 2 then starts the camera device 4. The high-definition camera records the video and stores it in the storage module, and then uploads it to the monitoring terminal via the wireless module.

[0041] The top of cabinet 1 is equipped with a monocrystalline silicon solar panel 8, which is connected to an energy storage power supply to power the various components; the bottom of cabinet 1 has an LED lighting light 9 equipped with a photosensitive switch, which automatically turns on when the light is dim. The fire extinguishing device 5 is a dry powder fire extinguisher, with the nozzle pointed towards the dense area of ​​electrical components 11 inside the cabinet, and it is activated when the smoke sensor detects the fire threshold.

[0042] In one embodiment, the focus is on security protection functions, and the technical features are configured as follows.

[0043] Cabinet 1 is made of stainless steel, and cabinet door 12 is equipped with a mechanical lock. Control device 2 uses PLC, smoke sensor is installed in a reasonable position on the top of the cabinet, and fire extinguishing device 5 is a suspended dry powder fire extinguishing device, with nozzles precisely directed towards densely populated areas such as contactors and circuit breakers via hoses.

[0044] The camera device 4 includes a high-definition camera with infrared night vision, a storage module with ample capacity, and a wireless communication module that can upload video recordings to the cloud monitoring terminal in real time. The pressure sensor 3 is a mechanical limit switch installed on the cabinet 1 near the latch of the cabinet door 12. When the cabinet door 12 is opened, the camera device 4 is immediately triggered to record images.

[0045] The rain shield 7U-shaped fixing bracket 71 is made of stainless steel, and the surface of the T-shaped slide 711 is specially treated to enhance wear resistance. The rain shield 72 fits precisely with the slide, and is driven by a servo motor and a lead screw 74 to ensure that the rain shield 72 moves quickly and accurately. When the humidity sensor detects the humidity threshold during rain, the rain shield 72 quickly moves up to the slot 712 and is attracted by the magnetic component 75 to block the cooling fan 6. When the humidity drops to a safe value, the rain shield 72 moves down to avoid the air outlet of the cooling fan 6.

[0046] The solar panel 8 is compatible with the energy storage power supply to meet power requirements; the bottom lighting 9 of the cabinet 1 has moderate power, and the photosensitive switch automatically turns on and off when the light is suitable. The cooling fan 6 is controlled by the control device 2 via a PWM signal, and its speed is adjusted proportionally according to the temperature sensor detection results.
