[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0043] Please refer to Figures 1 to 4 , wherein, Figure 1 a schematic diagram of an energy storage cabinet with an intelligent fire extinguishing system provided by the embodiments of the present application, Figure 2 a logic diagram of an energy storage cabinet with an intelligent fire extinguishing system provided by the embodiments of the present application, Figure 3 a circuit of an energy storage cabinet with an intelligent fire extinguishing system provided by the embodiments of the present application Figure 1 , Figure 4 a circuit of an energy storage cabinet with an intelligent fire extinguishing system provided by the embodiments of the present application Figure 2 .

[0044] In a first specific embodiment, the energy storage cabinet with an intelligent fire extinguishing system provided by the embodiments of the present application mainly comprises a cabinet body 1, which is provided with a fire extinguishing agent device 2, a detection device 3, a control device 4 and an exhaust device 5.

[0045] The fire extinguishing agent device 2 stores fire extinguishing medium, the detection device 3 is used to detect the fire in the cabinet body 1 in real time, the exhaust device 5 is used to exhaust the gas in the cabinet body 1, and the control device 4 is signal connected with the fire extinguishing agent device 2, the detection device 3 and the exhaust device 5, so as to realize that when the fire occurs in the cabinet body 1, the fire extinguishing agent device 2 sprays fire extinguishing medium for fire extinguishing, and the exhaust device 5 exhausts the gas for explosion prevention.

[0046] In view of the problems existing in the existing industrial and commercial energy storage cabinet fire extinguishing system mentioned in the background art, the technical solution realizes real-time detection, rapid response and effective control of the fire, especially improvement in the aspect of harmful gas exhaust, and significantly improves the fire safety performance of the energy storage cabinet through intelligent design.

[0047] In existing technologies, the fire suppression systems of energy storage cabinets often lack effective real-time monitoring and rapid response mechanisms, leading to delayed fire detection, rapid fire spread, and increased fire damage. Furthermore, existing systems rely on limited fire control methods, often depending on a single extinguishing technique, lacking comprehensive fire handling capabilities. In particular, they are inadequate in handling hazardous gases during a fire, increasing the risk of explosion.

[0048] This technical solution integrates a fire extinguishing agent device 2, a detection device 3, a control device 4, and an exhaust device 5 into the energy storage cabinet, forming an intelligent fire protection system. The control device 4, as the core of the system, is connected to the fire extinguishing agent device 2, detection device 3, and exhaust device 5 via signal links, achieving a high degree of coordination. When the detection device 3 detects a fire inside the cabinet 1 in real time, the control device 4 responds quickly, activating the fire extinguishing agent device 2 to spray the extinguishing medium for fire suppression. Simultaneously, the exhaust device 5 works in sync to expel harmful gases generated by the fire, preventing the risk of explosion due to gas accumulation.

[0049] This integrated design not only improves the timeliness of fire detection but also enhances fire control capabilities through diversified processing methods. Compared to traditional single fire extinguishing methods, this solution can address fires more comprehensively, including the two key aspects of fire extinguishing and gas venting, thereby significantly improving the fire safety performance of the energy storage cabinet.

[0050] Based on the above structural and process descriptions, it can be seen that the energy storage cabinet with an intelligent fire protection system has at least the following beneficial effects: the energy storage cabinet with an intelligent fire protection system realizes real-time detection, rapid response and effective control of fire in the energy storage cabinet, especially the timely discharge of harmful gases, thereby improving the fire safety performance of the energy storage cabinet and effectively solving the problems of untimely fire detection, single fire control methods and insufficient handling capacity in the existing technology.

[0051] It should be noted that the cabinet 1 of the energy storage cabinet should also be equipped with an energy storage device 9, which can provide stable power support for various components. In addition, an additional power supply can be provided, which should also be within the scope of this embodiment.

[0052] In addition, the extinguishing agent device 2 can be divided into two parts: an extinguishing agent storage device and a spraying device, with thermal aerosol as the extinguishing medium. For example... Figure 2 As shown, Figure 3 The thermal aerosol in the image represents extinguishing agent device 2; such as Figure 3 As shown, Figure 4 In the text, QRJ represents extinguishing agent device 2; such as Figure 4 As shown, Figure 4The fire-fighting QRJ and aerosol extinguishing device in the text represent extinguishing agent device 2.

[0053] like Figure 4 As shown, in some embodiments, the exhaust device 5 includes an intake valve 501, an exhaust valve 502, and an axial flow fan 503, which are connected in parallel to the power supply circuit of the control device 4, and each of the three circuits is equipped with a relay 6.

[0054] In this embodiment, the exhaust device 5 is designed to effectively expel harmful gases from the cabinet in the event of a fire, preventing potential explosions caused by gas accumulation. The exhaust device 5 consists of three main components: an intake valve 501, an exhaust valve 502, and an axial flow fan 503. These three components are connected in parallel to the power circuit of the control device 4, meaning they can operate simultaneously, and each component draws power directly from the control device 4.

[0055] The advantage of parallel connection is that even if one component fails, the others can continue to operate, thus improving system reliability. Furthermore, each circuit is equipped with a relay 6, which, upon receiving a signal from the control device 4, quickly responds and connects or disconnects the power supply to control the operating status of the intake valve 501, exhaust valve 502, and axial flow fan 503. This design allows the exhaust device 5 to start quickly, respond promptly to fire situations, and effectively expel gases, enhancing system safety and responsiveness.

[0056] In some cases, the venting device 5 is only activated when the extinguishing agent device 2 is activated; that is, the venting device 5 is dedicated to the exhaust of gases during fire extinguishing. Under normal conditions, the venting device 5 is in the closed state.

[0057] In some embodiments, the detection device 3 includes a smoke sensor 301 and a temperature sensor 302, both of which are connected in parallel to the power supply circuit of the control device 4.

[0058] In this embodiment, the detection device 3 is used to monitor the environmental conditions inside the energy storage cabinet in real time, so as to detect the fire in a timely manner. The detection device 3 consists of two types of sensors: a smoke sensor 301 and a temperature sensor 302. The smoke sensor 301 is specifically designed to detect smoke generated in the early stages of a fire, and can sense changes in the concentration of smoke particles within its field of view, thus issuing an alarm in the early stages of fire development. The temperature sensor 302 is used to detect abnormal increases in ambient temperature. It can trigger an alarm when the temperature reaches a specific threshold, which is particularly useful for detecting fires that do not produce obvious smoke.

[0059] like Figure 2As shown, both sensors are connected in parallel to the power supply circuit of the control device 4, which allows them to work independently while drawing power from the same source.

[0060] It should be noted that the number of sensors is not limited in this embodiment, that is, regardless of the number of smoke sensors 301 and the number of temperature sensors 302, they are connected in parallel to the power supply circuit.

[0061] In some embodiments, the smoke sensor 301 is divided into a first smoke sensor 3011 and a second smoke sensor 3012, and the temperature sensor 302 is divided into a first temperature sensor 3021 and a second temperature sensor 3022. The first smoke sensor 3011 and the first temperature sensor 3021 transmit signals to the control device 4, and the second smoke sensor 3012 and the second temperature sensor 3022 transmit signals to the extinguishing agent device 2.

[0062] In this embodiment, the design of the detection device 3 achieves a division of labor in signal transmission by subdividing the smoke sensor 301 and the temperature sensor 302 into two sensors each, enhancing the reliability and redundancy of the system. Specifically, the first smoke sensor 3011 and the first temperature sensor 3021 are responsible for sending signals to the control device 4. This configuration ensures that the control device 4 can receive smoke and temperature signals from two different sensors, allowing real-time monitoring of the internal environment of the energy storage cabinet.

[0063] At the same time, the second smoke sensor 3012 and the second temperature sensor 3022 directly transmit signals to the extinguishing agent device 2. This design means that even if the control device 4 fails or signal transmission is blocked, the extinguishing agent device 2 can still independently receive smoke and temperature signals from the second smoke sensor 3012 and the second temperature sensor 3022, triggering the extinguishing action.

[0064] Through this division of labor, the system not only improves the accuracy of fire detection, but also enhances the robustness in various situations. This design does not rely on the performance of a single sensor, but rather on the coordinated work of multiple sensors to ensure that fire can be detected in a timely and accurate manner under any circumstances, triggering the appropriate extinguishing program and improving the fire safety performance of the energy storage cabinet. This configuration improves the overall reliability of the system, ensuring that it can respond quickly and effectively to fire in emergency situations.

[0065] As shown, Figure 2 Figure 3 ​Smoke 1 represents the first smoke sensor 3011, and Temperature 1 represents the first temperature sensor 3021. Smoke 2 represents the second smoke sensor 3012, and Temperature 2 represents the second temperature sensor 3022. Monitoring system represents the control device 4. Figure 4 and Figure 3 as shown, Figure 4 and Figure 4 Smoke YG1 represents the first smoke sensor 3011, and Temperature WG1 represents the first temperature sensor 3021. Smoke YG2 represents the second smoke sensor 3012, and Temperature WG2 represents the second temperature sensor 3022.

[0066] In some embodiments, the signal feedback mode of the smoke sensor 301 and the temperature sensor 302 is dry contact feedback.

[0067] In this embodiment, the smoke sensor 301 and the temperature sensor 302 use dry contact feedback to transmit signals to the control device 4 and other related devices, which are not limited to the first smoke sensor 3011 and the first temperature sensor 3021, and the second smoke sensor 3012 and the second temperature sensor 3022. As shown, Figure 2 Dry contact feedback is an electrical switching signal that typically changes between two states, "open" and "closed", corresponding to the opening and closing of the circuit.

[0068] The advantage of using dry contact feedback is its simplicity and reliability. Since dry contact does not involve the flow of current, it does not produce any current consumption except during state changes, making the system more energy efficient. At the same time, the signal of dry contact is clear and unambiguous, not easily disturbed by electrical noise, thereby improving the stability and reliability of the signal.

[0069] When the smoke sensor 301 or the temperature sensor 302 detects an abnormal situation, such as an increase in smoke concentration or a temperature rise exceeding the preset threshold, they will change the signal state from "open" to "closed" through dry contact, or vice versa, sending a clear alarm or action signal to the control device 4. This signal change can directly trigger the control device 4's preset emergency program, such as starting the audible and visual alarm 7, the exhaust device 5 or the fire extinguishing agent device 2, etc., thereby achieving rapid response and effective control of the fire situation.

[0070] As shown, Figure 4 Smoke 1 and the monitoring system are dry contact feedback, Temperature 1 and the monitoring system are dry contact feedback, and Hot Aerosol and the monitoring system are dry contact feedback. In addition, Smoke 2, Temperature 2 and Hot Aerosol can also be electrically activated.

[0071] As shown, Figure 2As shown, in some embodiments, the energy storage cabinet also includes an audible and visual alarm 7, which is connected in parallel with the fire extinguishing agent device 2 in the power supply circuit of the control device 4. A second smoke sensor 3012 is located at the parallel connection point of the audible and visual alarm 7 and the fire extinguishing agent device 2, and a second temperature sensor 3022 is located in the circuit of the fire extinguishing agent device 2, so as to achieve the following: when the second smoke sensor 3012 is closed, the audible and visual alarm 7 is activated; when the second smoke sensor 3012 is closed and the second temperature sensor 3022 is closed, the fire extinguishing agent device 2 is activated.

[0072] In this embodiment, an audible and visual alarm 7 is added to the energy storage cabinet design. It is connected in parallel with the fire extinguishing agent device 2 to the power circuit of the control device 4. This configuration allows the audible and visual alarm 7 and the fire extinguishing agent device 2 to simultaneously receive power signals from the control device 4. A second smoke sensor 3012 is located at the parallel connection point of the audible and visual alarm 7 and the fire extinguishing agent device 2, while a second temperature sensor 3022 is installed on the circuit of the fire extinguishing agent device 2.

[0073] This layout means that when the second smoke sensor 3012 (smoke sensor YG2) detects smoke and changes from an open state to a closed state, it will first trigger the audible and visual alarm 7, emitting an audible and visual alarm to alert personnel on site to the fire situation. This design allows for sufficient early warning in the initial stages of a fire, providing valuable time for personnel evacuation and initial fire response.

[0074] Furthermore, when the second smoke sensor 3012 closes and the second temperature sensor 3022 (temperature sensor WG2) also detects an abnormal temperature and closes, the fulfillment of these two conditions will trigger the activation of the extinguishing agent device 2, releasing the extinguishing medium to extinguish the fire. This design ensures that the extinguishing agent device 2 is only activated upon confirmation of a fire (through dual confirmation of smoke and temperature), thereby avoiding misoperation and unnecessary release of extinguishing agent.

[0075] In summary, this design improves the energy storage cabinet's response efficiency and accuracy to fires. Through the early warning of the audible and visual alarm 7 and the conditional activation of the fire extinguishing agent device 2, it achieves rapid response and effective control of fires, thereby enhancing the safety of the energy storage cabinet.

[0076] like Figure 2 As shown, Figure 3 The audible and visual alarm in the text represents the audible and visual alarm device 7; such as Figure 3 As shown, Figure 4 In the text, "BELL audible and visual alarm" represents audible and visual alarm device 7; such as... Figure 4 As shown, Figure 2 In the text, "BELL" represents the sound and light alarm device 7.

[0077] In some embodiments, the control device 4 includes a working condition machine 401, a power supply 402, and a monitor 403, the monitor 403 is in signal connection with the working condition machine 401, and the monitor 403 is used to display operation information and alarms.

[0078] In the present embodiment, the design of the control device 4 integrates three main components: the working condition machine 401, the power supply 402, and the monitor 403. The working condition machine 401 serves as the core processing unit of the control device 4, responsible for receiving signals from the detection device 3 and making logical judgments and decisions based on these signals to control other components of the energy storage cabinet.

[0079] The monitor 403 is an important part of the control device 4, which is in signal connection with the working condition machine 401, and receives the processing results and system state information of the working condition machine 401 in real time. The main function of the monitor 403 is to display the operation information and alarm signals of the energy storage cabinet, so that the operator can timely understand the working state of the energy storage cabinet, including any abnormal situation or fire alarm.

[0080] Through this integrated design, the control device 4 not only can realize real-time monitoring and control of the internal environment of the energy storage cabinet, but also can provide an intuitive user interface for the operator to effectively manage and respond to emergencies. This design improves the intelligent level of the energy storage cabinet, enhances the reliability and user-friendliness of the system, and ensures that correct measures can be taken quickly in the event of a fire.

[0081] As shown in FIG. 1, Figure 2 , the display / alarm in Figure 3 represents the monitor 403; as shown in FIG. 2, Figure 3 , the GK working condition machine in Figure 4 represents the working condition machine 401; as shown in FIG. 3, Figure 4 , the working condition machine in Figure 5 represents the working condition machine 401.

[0082] It should be noted that the power supply 402 can use the energy storage device 9 to provide stable power support for each component.

[0083] Please refer to Figure 6 and Figure 5 , among which, Figure 6 is a front view of the energy storage cabinet with an intelligent fire-fighting system provided by the present embodiment, Figures 7 to 11 is a rear view of the energy storage cabinet with an intelligent fire-fighting system provided by the present embodiment.

[0084] In some embodiments, the energy storage cabinet further includes an integrated electric control box 8, which is arranged in the cabinet body 1.

[0085] In this embodiment, the integrated electrical control box 8 centralizes most of the original bottom electrical control components inside the box, which reduces the wiring requirements inside the cabinet 1 and thus reduces the complexity of assembly. Since the components are centrally managed, the cabinet 1 and the electrical control box 3 can be assembled independently, which allows parallel assembly and saves overall assembly time.

[0086] In some embodiments, the integrated electrical control box 8 is detachably connected to the cabinet 1 by fasteners. This design allows the electrical control box 3 to be quickly disassembled and installed when needed, facilitating maintenance and upgrades while maintaining the integrity and stability of the cabinet structure.

[0087] In some embodiments, the integrated electrical control box 8 integrates the first components and a connector, which has a first connection end and a second connection end. The first connection end is electrically connected to the first components, and the second connection end is used to realize the external connection of the integrated electrical control box 8.

[0088] It should be noted that the first components include but are not limited to components, terminal blocks.

[0089] The connector design in the integrated electrical control box 8 further simplifies the assembly process. The first and second connection ends of the connector are respectively arranged towards the inside and outside of the box, making the connection of external components to the electrical control box 3 direct and simple. This design reduces the complex wiring work inside the cabinet 1 in traditional designs, reduces the error rate, and improves the accuracy and efficiency of assembly.

[0090] Specifically, the advantages of the integrated electrical control box 8 are as follows.

[0091] The design of the integrated electrical control box 8 allows the assembly of the cabinet 1 and the electrical control box 3 to be performed separately, which means that they can be performed simultaneously in different work areas or work stages without waiting for the cabinet 1 to be completely assembled before starting the installation of the electrical control box 3. This parallel operation significantly reduces the overall assembly time and improves production efficiency.

[0092] The connector design of the integrated electrical control box 8 simplifies the wiring work. In traditional designs, the connection between external components and components inside the cabinet 1 requires precise wiring and connection, which not only increases the complexity of assembly but also increases the risk of errors. In this scheme, external components only need to be connected to the connector of the integrated electrical control box 8, greatly simplifying the wiring process, reducing the difficulty of assembly, and also reducing the risk of failure due to wiring errors.

[0093] The design of the integrated electric control box 8 improves the efficiency of equipment debugging. In traditional designs, debugging work needs to be carried out after all components and wiring are installed in place, which limits the flexibility of debugging work. The present scheme allows separate debugging of components inside the integrated electric control box 8 first, and then overall system debugging after confirmation, which not only improves the debugging efficiency, but also helps to quickly locate and solve problems.

[0094] The design of the integrated electric control box 8 improves the maintainability of the equipment. Since the integrated electric control box 8 can be used as a general component in different types of cabinet 1, when components need to be replaced or repaired, the electric control box 3 can be quickly disassembled and replaced, without having to operate the entire cabinet 1. This modular design makes maintenance more convenient, reduces maintenance costs, and also improves the flexibility and applicability of the energy storage cabinet.

[0095] In some embodiments, the first component includes a high-voltage box, a circuit breaker, an electric energy meter, and an industrial computer, which are all built-in in the integrated electric control box 8 to achieve efficient electrical control and management of the energy storage cabinet. The high-voltage box is responsible for bearing and distributing high voltage, the circuit breaker is used for overload protection of the circuit, the electric energy meter monitors energy consumption, and the industrial computer serves as the control center of the entire system. Such integrated design simplifies the internal structure of the electric control box, improves the convenience of operation and the reliability of the system.

[0096] Please refer to Figure 7 , wherein, Figure 8 the plug wiring diagram of the movable connector provided by the embodiment of the present application, Figure 9 the socket wiring diagram of the movable connector provided by the embodiment of the present application, Figure 10 the external wiring diagram of the fixed connector provided by the embodiment of the present application, Figure 11 the internal wiring diagram of the fixed connector provided by the embodiment of the present application, Figure 7 the structure diagram of the energy storage cabinet with intelligent fire fighting system provided by the embodiment of the present application.

[0097] As shown in Figure 8 and Figure 9 , the technical scheme relates to a design of a movable connector for an integrated electric control box to realize electrical connection between the inside and outside of the electric control box. The movable connector is composed of two main parts: a socket and a plug. The socket is fixed to the box body, and the plug cooperates with the socket, and the two are connected to realize transmission of electrical signals.

[0098] Specifically, the socket and plug of the movable connector are designed with specific connection terminals. The first connection terminal is located on the side of the socket facing away from the plug, and this terminal is used for electrical connection with internal components of the cabinet, such as high-voltage boxes, circuit breakers, etc. Correspondingly, the second connection terminal is located on the side of the plug facing away from the socket, and this terminal is used for external connection of the cabinet, realizing electrical connection between the integrated electric control cabinet and external equipment.

[0099] In some cases, the movable connector adopts an aviation plug and an aviation socket.

[0100] As shown in Figure 10 and Figure 5 , the technical solution involves the design of a fixed connector for realizing stable connection between internal components of an integrated electric control cabinet and external equipment. The fixed connector is composed of a fixed body, which is fixed on the cabinet as the core part of the connector. The design feature of the fixed connector is that the first connection terminal and the second connection terminal are respectively fixed on the inner and outer sides of the fixed body.

[0101] Specifically, the first connection terminal faces the internal side of the cabinet and is responsible for electrical connection with internal components of the cabinet, such as high-voltage boxes, circuit breakers, etc. This internal connection is usually to connect the electrical signals or power of these components to the outside of the cabinet to realize the control and monitoring functions of the equipment. The second connection terminal faces the external side of the cabinet and is used for connection with external equipment or cables. Such a design allows external equipment to establish electrical connection with internal components of the cabinet through this fixed terminal, thereby achieving the purpose of external control or data transmission.

[0102] In some cases, the fixed connector adopts a phoenix terminal.

[0103] It should be noted that the design of the integrated electric control cabinet 8 provides high flexibility and adaptability, and is not limited to using only one of the movable connector or the fixed connector. In fact, the electric control cabinet 3 can simultaneously use the movable connector and the fixed connector according to actual application requirements to meet different connection requirements and environmental conditions.

[0104] In some embodiments, the energy storage cabinet further comprises an energy storage converter 10 and a liquid cooling unit 11 arranged in the cabinet body 1.

[0105] The energy storage converter 10 is one of the core components in the energy storage system, which is responsible for converting the direct current (DC) stored in the energy storage device 9 into alternating current (AC) for power grid or other equipment. In this embodiment, the energy storage converter 10 is directly connected to the integrated electric control cabinet 8, which can simplify electrical connection, reduce energy loss in the conversion process, and improve the response speed and control accuracy of the system.

[0106] The liquid cooling unit 11 is used to provide cooling for the energy storage device 9, so as to maintain its operation at an optimal temperature, improve the energy storage efficiency and prolong the service life. The liquid cooling unit 11 is connected to the energy storage device 9 through the liquid cooling pipeline 12, ensuring that the cooling liquid can circulate efficiently and take away the heat generated by the energy storage device 9. In this embodiment, the liquid cooling unit 11 is also connected to the integrated electric control box 8, which makes the electric control box 3 able to monitor and manage the liquid cooling system, optimize the cooling effect and reduce the land occupation of the cooling system.

[0107] Please continue to refer to Figure 6 and Figure 6 In some embodiments, the top of the cabinet 1 is provided with lifting rings 101 and explosion venting plates 102. The lifting rings 101 are distributed at the four corners of the top of the cabinet 1, which makes the cabinet 1 convenient to be lifted and hoisted by lifting equipment, especially when the energy storage cabinet needs to be moved or installed, the lifting rings provide stable lifting points, ensuring the safety and convenience of operation. The explosion venting plates 102 are safety devices that can quickly release pressure when the internal pressure of the cabinet abnormally rises, preventing the cabinet from exploding or being damaged due to excessive internal pressure, thereby protecting personnel safety and equipment integrity. The arrangement of these two components enhances the practicality and safety of the cabinet 1.

[0108] In this embodiment, the front side of the cabinet 1 is equipped with openable and closable cabinet doors for easy operation and maintenance of the internal components. In order to monitor the opening and closing state of the cabinet doors in real time, ensure safety and convenience, the front side of the cabinet 1 is provided with a travel switch 103. This travel switch 103 can send a signal when the cabinet door is opened or closed, prompting the operator of the state of the cabinet door, and can also be used to feedback to the control system whether the cabinet door is properly closed, thereby ensuring the safe operation of the equipment.

[0109] As shown in ​ , the rear side of the cabinet 1 integrates multiple functional components. The working condition machine antenna 104 is used for wireless communication, the nameplate 105 identifies the information of the equipment, the dehumidifier 106 is used to adjust the humidity in the cabinet to prevent the equipment from being damp. The guide rail terminal 107 provides a quick connection and fixing method for internal components, and the electric control box grounding row 108 and the cabinet grounding point 109 are used to ensure the safe grounding of the equipment to prevent electrical faults and lightning damage. The arrangement of these components not only enhances the functionality of the cabinet 1, but also improves the convenience and safety of its operation.
