Description

Technical Field

[0001] This invention relates to the field of power energy storage cabinet technology, and in particular to an energy-saving smart grid power energy storage cabinet. Background Technology

[0002] Against the backdrop of the rapid advancement of smart grid construction, power storage cabinets, as core equipment for grid energy storage, peak shaving and valley filling, and emergency power supply, are widely used in outdoor substations, distributed photovoltaic power stations, and other scenarios. They integrate a large number of battery modules and control modules, continuously generating heat during operation. Temperature control within the cabinet directly affects battery cycle life and equipment operational safety; therefore, heat dissipation and protection have become core requirements for the design and application of power storage cabinets. At the same time, the complex outdoor environment with its high temperature, humidity, dust, and sunlight also places higher demands on the ventilation adaptability and sealing protection of the energy storage cabinets.

[0003] Existing power storage cabinets mostly employ fixed vents or manually adjustable louvers for heat dissipation and ventilation, which cannot adjust the ventilation volume according to changes in internal temperature and outdoor environmental conditions. This presents significant technical defects: insufficient ventilation under high-temperature conditions can lead to delayed heat dissipation and cause safety hazards due to excessive temperature rise inside the cabinet; in low-temperature, rainy, snowy, or dusty weather, the vents cannot be effectively sealed, allowing rainwater and dust to seep into the cabinet, corroding internal electrical components and reducing the equipment's lifespan. The existing structure is no longer suitable for the efficient, safe, and intelligent operation requirements of smart grids for energy storage equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an energy-saving smart grid power storage cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving smart grid power storage cabinet, comprising a distribution cabinet and two door panels with self-locking function hinged to the front of the distribution cabinet, wherein at least two support blocks are fixedly fixed at equal intervals at the bottom of the distribution cabinet, characterized in that: a closing mechanism for adjusting the size of the natural ventilation opening is installed on the upper side of one side of the distribution cabinet, and a sunshade mechanism for blocking direct sunlight is installed on the upper side of the distribution cabinet, and a heat dissipation mechanism for rapid heat dissipation is installed on the lower rear side of the distribution cabinet; a soft-connection control module is configured inside the distribution cabinet, the soft-connection control module is electrically connected to the closing mechanism and the heat dissipation mechanism respectively, and an environmental sensing component electrically connected to the soft-connection control module is also provided inside the distribution cabinet, the soft-connection control module adjusts the ventilation opening of the closing mechanism and the operating status of the heat dissipation mechanism based on the monitoring data of the environmental sensing component, thereby realizing intelligent control of energy-saving heat dissipation inside the cabinet.

[0006] Preferably, the sealing mechanism includes a sealing opening through one side of the distribution cabinet, with sealing plates vertically and equidistantly hinged at the sealing opening, a triangular adjusting block tightly fitted at the lower end of the sealing plate, and an adjusting plate fixedly connected to one side of the triangular adjusting block inside the distribution cabinet.

[0007] Preferably, the sunshade mechanism includes support columns symmetrically mounted on the distribution cabinet by bolts, with inverted T-shaped grooves opened on the same side of the two support columns, into which a sunshade plate is slidably inserted, and a barrier plate is installed abutting on one side of the sunshade plate, with the barrier plate installed on the support columns by fixing bolts.

[0008] Preferably, the heat dissipation mechanism includes a heat dissipation vent that extends through the lower rear side of the distribution cabinet, an exhaust plate that is vertically hinged to the heat dissipation vent, and a fixing block that is fixed to the heat dissipation vent on the inner wall of the distribution cabinet. A fixing frame is fixed to the fixing block, and a fan is installed on the fixing frame.

[0009] Preferably, the adjusting plate is vertically mounted with an electric telescopic rod, which is installed on a fixed plate and fixedly connected to the inner wall of the distribution cabinet.

[0010] Preferably, the electric telescopic rod and the adjusting plate are installed inside the protective cover, and the protective cover is fixedly connected to the inner wall of the power distribution cabinet.

[0011] Preferably, the environmental sensing component includes a temperature sensing unit, a humidity sensing unit, and a dust sensing unit. Each sensing unit is installed in the functional module installation area inside the power distribution cabinet, and the signal output terminal of each sensing unit is communicatively connected to the signal input terminal of the soft-connect control module. The soft-connect control module receives real-time monitoring data from each sensing unit and performs data analysis and processing.

[0012] Preferably, the soft-connect control module includes a main control unit, a drive unit, and a communication unit. The main control unit is electrically connected to the drive unit and the communication unit, respectively. The drive unit is electrically connected to the electric telescopic rod of the enclosed mechanism and the fan of the heat dissipation mechanism, respectively. The main control unit outputs control commands through the drive unit to control the extension and retraction stroke of the electric telescopic rod and the start, stop, and operating power of the fan. The communication unit is used to realize bidirectional data interaction between the soft-connect control module and the external power grid control system.

[0013] Preferably, the soft-control module further includes a storage unit, which is electrically connected to the main control unit. The storage unit pre-stores multiple sets of control thresholds corresponding to temperature, humidity, and dust concentration, as well as linkage control strategies for the sealing mechanism and heat dissipation mechanism. The main control unit automatically generates control commands based on the matching results of real-time monitoring data from the environmental sensing component and the pre-stored control strategies.

[0014] Preferably, the soft-connect control module is configured with an energy-saving control mode. In the energy-saving control mode, the soft-connect control module prioritizes controlling the closure mechanism to adjust the ventilation opening to achieve natural ventilation and heat dissipation. When the monitoring data of the environmental sensing component reaches the preset forced heat dissipation threshold, the fan of the heat dissipation mechanism is started step by step and its operating power is adjusted. When the monitoring data drops to the safety threshold, the soft-connect control module gradually reduces the fan operating power until it is turned off, and simultaneously controls the closure mechanism to reduce the ventilation opening until it is closed.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This solution, through the configuration of a soft-connection control module and environmental sensing components, combined with the linkage of the enclosed mechanism's electric telescopic rods and sealing plates, achieves intelligent automatic adjustment of the ventilation opening. This completely solves the problem that traditional energy storage cabinets with fixed ventilation openings or manually adjustable louvers cannot adjust the ventilation volume as needed. Based on environmental data such as temperature and humidity inside the cabinet, dust concentration, and outdoor light intensity, it can precisely match ventilation requirements. During high temperatures, the opening is increased to improve heat dissipation efficiency; during low temperatures or harsh environments, the opening is reduced or even closed, effectively avoiding heat dissipation lag. Simultaneously, it prevents dust and rainwater from seeping into the cabinet and corroding electrical components, improving the equipment's adaptability to complex outdoor environments.

[0017] 2. This solution incorporates an energy-saving control mode, combined with a shading mechanism for physical sun protection and cooling, achieving energy-efficient operation of the energy storage cabinet. The shading panel effectively blocks direct sunlight, reducing cabinet temperature rise at the source and minimizing energy loss during heat dissipation. The soft-connect control module prioritizes natural ventilation and heat dissipation through a closed mechanism, only activating the fans in stages when the forced cooling threshold is reached. Furthermore, the fan power is dynamically adjusted according to cooling demand, avoiding energy waste from continuous high-power fan operation. This ensures effective heat dissipation while minimizing equipment operating energy consumption, aligning with the energy-saving development needs of smart grids.

[0018] 3. This solution constructs a multi-dimensional intelligent control and remote interaction system, improving the intelligence level and ease of operation and maintenance of the power storage cabinet. The soft-connect control module incorporates algorithms such as data fusion and threshold matching, which can comprehensively analyze multi-source data from environmental sensing components and automatically generate precise control commands to achieve coordinated operation of the enclosure and heat dissipation mechanisms. The communication unit supports wired and wireless dual-mode communication, enabling bidirectional data interaction with the external power grid control system. It can not only upload data on the cabinet's internal environment and equipment operation but also receive remote control commands, achieving remote intelligent control of the enclosure and heat dissipation mechanisms without on-site manual operation, significantly reducing operation and maintenance costs and adapting to the remote management and control requirements of smart grids.

[0019] In summary, this solution deeply integrates mechanical structure and soft-touch control technology to optimize the heat dissipation and protection system of the power storage cabinet from multiple dimensions, including structural design, operation control, and intelligent interaction. It not only solves the technical defects of traditional products, such as rigid ventilation regulation and difficulty in balancing heat dissipation and protection, but also realizes energy-saving and intelligent operation of the equipment. At the same time, it improves the environmental adaptability and ease of operation and maintenance of the equipment, ensures the stable and safe operation of the battery modules and control modules inside the energy storage cabinet, and extends the service life of the equipment.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] See Figures 1 to 13 This invention discloses an energy-saving smart grid power storage cabinet, comprising a distribution cabinet 2 and two self-locking door panels 4 hinged to the front of the distribution cabinet 2, at least two support blocks 1 equidistantly fixed to the bottom of the distribution cabinet 2, a closing mechanism for adjusting the size of the natural ventilation opening installed on one side of the distribution cabinet 2, and a sunshade mechanism for shielding the distribution cabinet 2 from direct sunlight. A temperature sensor for detecting the internal temperature is also installed inside the distribution cabinet 2. A heat dissipation mechanism for rapid heat dissipation is installed on the lower rear side of the distribution cabinet 2. The overall framework of the energy-saving smart grid power storage cabinet is constructed through the distribution cabinet 2, door panels 4, support blocks 1, closing mechanism, sunshade mechanism, and heat dissipation mechanism, integrating ventilation opening adjustment, sunshade, and rapid heat dissipation functions, providing a core structural foundation for energy-saving heat dissipation and protection of the power storage cabinet.

[0037] The power distribution cabinet 2 is equipped with a soft-connection control module, which is electrically connected to the enclosure mechanism and the heat dissipation mechanism. The power distribution cabinet 2 is also equipped with an environmental sensing component that is electrically connected to the soft-connection control module. The soft-connection control module adjusts the ventilation opening of the enclosure mechanism and the operating status of the heat dissipation mechanism based on the monitoring data of the environmental sensing component, so as to realize intelligent control of energy-saving heat dissipation in the cabinet.

[0038] Specifically, the enclosure mechanism includes a sealing opening through one side of the distribution cabinet 2, with sealing plates 7 vertically and equidistantly hinged at the sealing opening. A triangular adjusting block is tightly fitted to the lower end of the sealing plate 7, and an adjusting plate 13 is fixedly connected to one side of the triangular adjusting block inside the distribution cabinet 2. Through the sealing opening, sealing plate 7, triangular adjusting block, adjusting plate 13, and distribution cabinet 2, the opening angle of the sealing plate 7 can be easily adjusted to control the size of the natural ventilation opening and adapt to the ventilation and heat dissipation needs of different working conditions; the sunshade mechanism includes... Support columns 5 are symmetrically installed on the distribution cabinet 2 by bolts. Inverted T-shaped grooves are opened on the same side of the two support columns 5. The sunshade 3 is slidably inserted into the inverted T-shaped grooves. A barrier plate 6 is installed on one side of the sunshade 3. The barrier plate 6 is installed on the support column 5 by fixing bolts. Through the support columns 5, inverted T-shaped grooves, sunshade 3, barrier plate 6, fixing bolts, and distribution cabinet 2, it is easy to block direct sunlight and reduce the internal temperature rise of the cabinet. At the same time, it can realize the quick installation and removal of the sunshade 3.

[0039] In this invention, the heat dissipation mechanism includes a heat dissipation vent that extends through the lower rear side of the distribution cabinet 2. An exhaust plate 8 is vertically hinged to the heat dissipation vent, and a fixing block 9 is fixedly connected to the inner wall of the distribution cabinet 2. A fixing frame 10 is fixedly connected to the fixing block 9, and a fan 11 is mounted on the fixing frame 10. Through the heat dissipation vent, exhaust plate 8, fixing block 9, fixing frame 10, fan 11, and distribution cabinet 2, heat inside the cabinet is actively dissipated, achieving rapid forced heat dissipation of the cabinet. The exhaust plate 8 assists in regulating the airflow for heat dissipation. An electric telescopic rod 12 is vertically mounted downwards on an adjusting plate 13, and the electric telescopic rod 12 is mounted on the fixing plate. The fixed plate is fixedly connected to the inner wall of the distribution cabinet 2, and the electric telescopic rod 12 is electrically connected to the soft-connection control module. Through the adjustment plate 13, the electric telescopic rod 12, the fixed plate, and the distribution cabinet 2, it is easy to drive the sealing plate 7 to open and close automatically, realize the automatic adjustment of the ventilation opening size, and improve the accuracy of heat dissipation control. The electric telescopic rod 12 and the adjustment plate 13 are installed inside the protective cover 14, and the protective cover 14 is fixedly connected to the inner wall of the distribution cabinet 2. Through the electric telescopic rod 12, the adjustment plate 13, the protective cover 14, and the distribution cabinet 2, it is easy to protect the internal adjustment components, prevent dust and debris from entering, and ensure the stable and reliable operation of the adjustment mechanism.

[0040] Specifically, the environmental sensing components include a temperature sensing unit, a humidity sensing unit, and a dust sensing unit. Each sensing unit is located within the functional module installation area inside the power distribution cabinet 2, and the signal output of each sensing unit is communicatively connected to the signal input of the soft-connect control module. Each sensing unit acquires monitoring data according to a preset acquisition frequency, and after signal amplification, filtering, and analog-to-digital conversion, the data is transmitted to the soft-connect control module. The soft-connect control module normalizes the received multi-dimensional monitoring data using the following normalization algorithm: Where X represents the raw monitoring data collected by the sensing unit. This is the preset minimum value for this type of monitoring data. This is the preset maximum value for this type of monitoring data. The data is normalized standard data; the Softcom control module receives the normalized real-time monitoring data from each sensing unit and performs data analysis and processing, and determines the heat dissipation and protection requirements of the cabinet and surrounding environment based on the processing results.

[0041] Specifically, the Softcom control module includes a main control unit, a drive unit, and a communication unit. The main control unit is electrically connected to both the drive unit and the communication unit. The drive unit is electrically connected to the electric telescopic rod 12 of the enclosed mechanism and the fan 11 of the heat dissipation mechanism. The main control unit has a built-in multi-dimensional data fusion algorithm to perform weighted fusion processing on the normalized data transmitted by the environmental sensing components. The fusion algorithm is as follows: Where S is the integrated environmental assessment value after fusion. Let be the weighting coefficient of the i-th type of monitoring data. Let be the normalized value of the i-th type of monitoring data, n be the number of monitoring data types, and the weight coefficients satisfy . The weighting coefficients are dynamically adjusted based on the operating conditions of the energy storage cabinet. The main control unit generates corresponding control commands based on the comprehensive environmental assessment value S, and converts the control commands into electrical signals through the drive unit to control the extension and retraction stroke of the electric telescopic rod 12 and the start / stop and operating power of the fan 11. The extension and retraction stroke of the electric telescopic rod 12 is linearly related to the opening and closing angle of the sealing plate 7, and the operating power of the fan 11 is positively related to the heat dissipation airflow. The communication unit is used to realize bidirectional data interaction between the soft communication control module and the external power grid control system, uploading the comprehensive environmental assessment value, the execution status of the control commands, and the equipment operating parameters to the external power grid control system, while receiving remote control commands and parameter configuration information issued by the external power grid control system.

[0042] Specifically, the Softcom control module also includes a storage unit, which is electrically connected to the main control unit. The storage unit pre-stores multiple sets of control thresholds corresponding to temperature, humidity, and dust concentration, as well as linkage control strategies for the sealing mechanism and heat dissipation mechanism. The control thresholds include natural ventilation threshold ranges, forced heat dissipation start thresholds, forced heat dissipation stop thresholds, and sealing protection thresholds. Each threshold range is non-overlapping and has a gradient distribution. The main control unit compares the real-time monitoring data of the environmental sensing component with the pre-stored control thresholds and completes strategy matching by combining the pre-stored linkage control strategies. The matching process adopts the nearest matching algorithm, that is, when the real-time comprehensive environmental assessment value S falls into a certain threshold range, the linkage control strategy corresponding to that range is directly matched. If the real-time comprehensive environmental assessment value S exceeds the preset threshold range, an emergency control strategy is matched. The main control unit automatically generates control commands based on the matching results and simultaneously stores the real-time monitoring data, strategy matching results, and control command generation information in the storage unit in real time, forming an operation data ledger. The storage unit supports the cyclic overwriting and fixed-point retrieval of historical data.

[0043] Specifically, the Softcom control module is equipped with an energy-saving control mode, which is the default operating mode of the Softcom control module. In the energy-saving control mode, the Softcom control module follows the control principle of "natural ventilation priority, forced heat dissipation on demand and graded start-up". First, it obtains real-time monitoring data through the environmental sensing component and generates a comprehensive environmental assessment value S. When S falls within the natural ventilation threshold range, the Softcom control module only controls the extension and retraction of the electric telescopic rod 12 of the enclosure mechanism to adjust the ventilation opening of the sealing plate 7. The adjustment value of the ventilation opening is obtained by matching the comprehensive environmental assessment value S with the natural ventilation opening mapping table to achieve pure natural ventilation heat dissipation. When the real-time monitoring data of the environmental sensing component reaches the preset forced heat dissipation start-up threshold, the Softcom control module first maintains the current ventilation opening of the enclosure mechanism, and then starts the fan 11 of the heat dissipation mechanism step by step and adjusts its operating power. The power adjustment of the fan 11 adopts a stepped increase method, each The first-level power increase corresponds to the preset comprehensive environmental assessment value increment, until the operating power of fan 11 matches the heat dissipation requirements; when the monitoring data drops to the preset forced heat dissipation stop threshold, the soft-connect control module first gradually reduces the operating power of fan 11 until it shuts down, with the power reduction step consistent with the increase step, and then synchronously controls the electric telescopic rod 12 of the sealing mechanism to extend and retract in the opposite direction, gradually reducing the ventilation opening of the sealing plate 7, until the comprehensive environmental assessment value S falls into the sealing protection threshold range and the sealing plate 7 is completely closed. During the entire control process, the soft-connect control module collects the environmental monitoring data after the control in real time, and corrects the control command through the negative feedback adjustment algorithm, so that the environment inside the cabinet is always maintained in the safe operating range. The core of the negative feedback adjustment algorithm is: according to the deviation value between the monitoring data after the control and the safety threshold, adjust the extension and retraction of the electric telescopic rod 12 or the operating power of fan 11 according to the preset ratio, until the deviation value approaches zero.

[0044] More specifically, the communication unit supports both wired and wireless data interaction methods. Wired communication uses an industrial bus communication protocol, while wireless communication uses a low-power IoT communication protocol. The communication unit has a built-in communication mode switching algorithm. Where M is the communication mode ultimately selected by the communication unit. It is a wired communication mode. This represents the wireless communication mode, where R is the real-time packet loss rate of the communication link. Here, Q represents the preset packet loss rate threshold, and Q is the connectivity quality value of the wired communication link. To preset a connectivity quality threshold, the soft-connection control module receives remote control commands from the external power grid control system via the communication unit. After decoding and verification by the communication unit, the remote control commands are transmitted to the main control unit. The main control unit parses the compliant commands and converts them into execution signals. Through the drive unit, it controls the electric telescopic rod 12 of the enclosure mechanism and the fan 11 of the heat dissipation mechanism to complete the corresponding actions, realizing remote intelligent control of the enclosure mechanism and the heat dissipation mechanism. At the same time, the communication unit encodes and packages the normalized environmental monitoring data, comprehensive environmental assessment values, and equipment operating status parameters inside the distribution cabinet 2, and uploads them to the external power grid control system according to the preset upload frequency. The uploaded data uses data verification codes for fault tolerance processing to ensure the accuracy and integrity of data transmission.

[0045] More specifically, the environmental sensing component also includes a light sensing unit. This light sensing unit is installed on the outer wall of the distribution cabinet 2 facing direct sunlight and is electrically connected to the soft-connect control module. The light sensing unit acquires real-time light intensity data I from the outside of the distribution cabinet 2 according to the unified acquisition frequency of the environmental sensing component, and transmits it to the soft-connect control module after signal processing. The soft-connect control module normalizes the real-time light intensity data and generates an auxiliary control prompt signal for the shading mechanism using a light threshold determination algorithm. The light threshold determination algorithm is as follows: Where T represents the type of auxiliary control prompt signal. This is the normalized value of light intensity. For strong light threshold, The threshold for low light intensity, and , This serves as a strong indication that the sun visor 3 is fully deployed. This is a weak warning signal that the sun visor has been deployed in three parts. The signal indicates no action when the sunshade 3 is retracted; the auxiliary control signal is linked to the cabinet's overall environmental assessment value S for analysis. Furthermore, when S is at the upper edge of the natural ventilation threshold range, the soft-control module will assign a weighting coefficient to the illumination data. Dynamically boosted, with a boosting coefficient of k and This enables coordinated control of the lighting environment and the internal heat dissipation environment of the cabinet.

[0046] The working principle of this energy-saving smart grid power storage cabinet is as follows:

[0047] Equipment placement and initial protection: Place the distribution cabinet 2, which is fixed with the support block 1, in the designated working position to ensure that the cabinet is stable. Close and lock the two self-locking door panels 4 on the front of the distribution cabinet 2 to provide initial protection for the power storage and related components inside the cabinet.

[0048] Manual adjustment of the sunshade mechanism: If the outside sunlight is strong, slide the sunshade 3 along the inverted T-shaped groove of the support column 5 and adjust it to a position that can completely block the direct sunlight on the top and sides of the distribution cabinet 2. Then tighten the fixing bolts on the support column 5 and limit the sunshade 3 with the barrier plate 6 to prevent it from shifting due to wind. This will block the direct sunlight, reduce the temperature rise inside the cabinet, and reduce heat dissipation energy consumption.

[0049] Environmental sensing and data processing: The environmental sensing components inside the power distribution cabinet 2 continuously collect data on temperature, humidity, and dust concentration inside the cabinet. The light sensing unit outside the power distribution cabinet 2 collects real-time light intensity data. All data are transmitted to the soft-connect control module after signal processing. The soft-connect control module normalizes and integrates the data to generate a comprehensive environmental assessment value and determine the heat dissipation and protection requirements inside the cabinet.

[0050] Natural ventilation and heat dissipation control: When the comprehensive environmental assessment value falls within the natural ventilation threshold range, the soft-connection control module sends a control command to the electric telescopic rod 12 of the enclosure mechanism. The electric telescopic rod 12 extends and retracts, driving the adjustment plate 13 to move, which in turn pushes the triangular adjustment block up and down. The triangular adjustment block lifts or lowers the sealing plate 7 at the sealing opening, adjusting the opening angle of the sealing plate 7, controlling the opening of the natural ventilation opening, so that the hot air in the cabinet can be naturally discharged through the ventilation opening, achieving natural ventilation and heat dissipation. Moreover, the electric telescopic rod 12 and the adjustment plate 13 are inside the protective cover 14 to prevent dust and debris from entering and affecting operation.

[0051] Forced heat dissipation control: When the comprehensive environmental assessment value reaches the forced heat dissipation start threshold, the soft-connect control module first maintains the current ventilation opening of the closed mechanism, and then sends start commands to the fan 11 of the heat dissipation mechanism step by step to adjust the operating power of the fan 11. The fan 11 generates negative pressure, blows open the exhaust plate 8 at the heat dissipation port, and allows the high temperature air in the cabinet to be quickly discharged through the heat dissipation port. Meanwhile, the cold air from outside continuously enters the cabinet through the ventilation port of the closed mechanism, forming an air circulation and achieving rapid forced heat dissipation.

[0052] Heat dissipation shutdown and sealing protection: When the monitoring data inside the cabinet drops to the forced heat dissipation shutdown threshold, the soft-connect control module gradually reduces the operating power of the fan 11 until it shuts down, and the exhaust plate 8 resets and closes under its own gravity; at the same time, the soft-connect control module controls the electric telescopic rod 12 to extend and retract in the opposite direction, driving the adjustment plate 13 and the triangular adjustment block to reset, gradually reducing the ventilation opening of the sealing plate 7. When the comprehensive environmental assessment value falls into the sealing protection threshold range, the sealing plate 7 closes completely to prevent external dust, rainwater, etc. from entering the cabinet and corroding electrical components.

[0053] Remote Interaction and Collaborative Control: The communication unit of the Softcom control module can automatically switch between wired and wireless communication modes based on the communication link status. It receives remote control commands from the external power grid control system, parses them, and controls the operation of the enclosure and heat dissipation mechanisms to achieve remote intelligent control. Simultaneously, it uploads environmental monitoring data and equipment operating status parameters from inside the cabinet to the external power grid control system for data interaction. Furthermore, the Softcom control module generates auxiliary control prompts for the shading mechanism based on monitoring data from the light sensing unit. When there is strong sunlight and the heat dissipation demand inside the cabinet approaches a threshold, it dynamically adjusts the weight of the light data to achieve collaborative control of the light environment and the heat dissipation environment inside the cabinet.

[0054] Equipment shutdown protection: When the energy storage cabinet is not in use, shut down all electrical components, check and confirm that the door panel 4 is in the closed and self-locking state, and complete the protection operation of the entire usage process.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

Each sensing unit is installed in the functional module installation area inside the power distribution cabinet (2), and the signal output terminal of each sensing unit is connected to the signal input terminal of the soft-connect control module. The soft-connect control module receives the real-time monitoring data of each sensing unit and performs data analysis and processing.

8. The energy-saving smart grid power storage cabinet according to claim 6, characterized in that: The soft-connect control module includes a main control unit, a drive unit, and a communication unit. The main control unit is electrically connected to the drive unit and the communication unit respectively. The drive unit is electrically connected to the electric telescopic rod (12) of the closed mechanism and the fan (11) of the heat dissipation mechanism respectively. The main control unit outputs control commands through the drive unit to control the extension and retraction stroke of the electric telescopic rod (12) and the start, stop and operating power of the fan (11). The communication unit is used to realize bidirectional data interaction between the soft-connect control module and the external power grid control system.

9. The energy-saving smart grid power storage cabinet according to claim 8, characterized in that: The soft-control module also includes a storage unit, which is electrically connected to the main control unit. The storage unit pre-stores multiple sets of control thresholds corresponding to temperature, humidity, and dust concentration, as well as linkage control strategies for the sealing mechanism and heat dissipation mechanism. The main control unit automatically generates control commands based on the matching results of real-time monitoring data from the environmental sensing component and the pre-stored control strategies.

10. The energy-saving smart grid power storage cabinet according to claim 8, characterized in that: The soft-connect control module is equipped with an energy-saving control mode. In the energy-saving control mode, the soft-connect control module prioritizes the control of the closed mechanism to adjust the ventilation opening to achieve natural ventilation and heat dissipation. When the monitoring data of the environmental sensing component reaches the preset forced heat dissipation threshold, the fan (11) of the heat dissipation mechanism is started step by step and its operating power is adjusted. When the monitoring data drops to the safety threshold, the soft-connect control module gradually reduces the operating power of the fan until it is turned off, and simultaneously controls the closed mechanism to reduce the ventilation opening until it is closed.
