Description

Technical Field

[0001] The present application relates to the technical field of power station equipment, and in particular to a fire extinguishing system for a box inverter room. Background Art

[0002] Inverter rooms serve as a critical hub in photovoltaic power plants, connecting photovoltaic power generation with the power grid. They house crucial equipment for converting solar energy into electricity, such as inverters and distribution systems. They not only maximize energy conversion efficiency but also ensure stable energy output, directly impacting the operational efficiency and reliability of the entire photovoltaic power plant. These rooms are typically distributed across a vast area within a photovoltaic power plant to accommodate the layout of the solar panel arrays. Each inverter room contains high-value electrical equipment that can generate high temperatures during operation, increasing the risk of fire. Due to their unique location and role, a fire could not only directly damage expensive equipment but could also trigger wider grid failures, impacting the power supply of the entire plant. Furthermore, inverter rooms are often located in remote or inaccessible areas, making timely emergency response more challenging.

[0003] Conventional fire safety systems for PV power plants typically include basic fire detectors and manual fire-fighting equipment, such as fire extinguishers. These systems often rely on the timely response and operation of on-site personnel. In some cases, automatic sprinkler or foam fire-fighting systems are also used. However, these traditional fire response measures have certain limitations in PV power plant environments. For example, manual fire-fighting equipment requires manual operation, which can be difficult to implement in a large or dispersed PV plant. Furthermore, water or foam fire-fighting systems may not be effective in extinguishing rapidly spreading electrical fires and may cause additional damage to electrical equipment.

[0004] For widely distributed and densely populated inverter rooms, on-site personnel may not be able to reach the fire scene immediately in an emergency, and traditional automatic fire extinguishing systems may not be able to provide the most effective response to a specific fire situation. Therefore, a fire extinguishing system for inverter rooms is urgently needed to address the technical problem of slow fire response caused by relying on manual labor. Utility Model Content

[0025] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0026] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0027] Existing technologies primarily rely on traditional fire detection and extinguishing methods, such as basic smoke detectors and manually operated fire extinguishers. These devices can detect the earliest signs of a fire when smoke or an abnormally high temperature rise appears. However, this approach often lacks speed and specificity in fire response, especially in equipment-intensive and fire-sensitive environments like inverter rooms. Existing fire extinguishing systems often lack precise control over specific areas, potentially reducing fire extinguishing efficiency and causing additional damage to equipment. In some cases, particularly in power plants with large staff numbers, regular manual inspections are still relied upon to identify potential fire risks. This requires on-site personnel to extinguish fires in their early stages. While effective in initial fires, these methods can be unavailable when the site is unattended or personnel are unable to reach it in a timely manner. This means that existing technologies cannot provide real-time monitoring and alerts.

[0028] In response to the above technical problems, the present invention provides a fire extinguishing system for a box inverter room. By installing a fire detection module and an environmental detection module, fire risks and environmental conditions can be monitored in real time. This not only improves the speed of fire detection, but also increases the possibility of fire prevention. Carbon dioxide fire extinguishing is adopted, and the fire extinguishing agent is delivered to the fire source quickly and effectively through the gas transportation pipeline. Through the remote communication module, key monitoring data can be sent to the remote terminal, so that operation and maintenance personnel can understand the situation in real time and make decisions even if they are not on site. This application effectively improves the efficiency of fire extinguishing while reducing potential damage to equipment.

[0029] This application is primarily intended for use in inverter rooms with multiple independent spaces, complex equipment, or those storing flammable materials. Examples include substations in photovoltaic power plants and control rooms in industrial manufacturing areas. In these scenarios, the fire extinguishing system not only provides efficient fire suppression but also reduces the risk of fire through data monitoring, thereby ensuring the safety of equipment and personnel and minimizing economic losses.

[0030] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0032] like Figure 1 and Figure 2 As shown, the present invention provides a fire extinguishing system for a box inverter room. This fire extinguishing system includes a fire detection module 10, a fire extinguishing mechanism, an environmental monitoring module, and an alarm module 40. The fire detection module monitors the fire risk within the box inverter room in real time. The fire detection module 10 is mounted on the ceiling of the box inverter room, ensuring maximum coverage of the entire room. This location enables the fire detection module 10 to quickly sense any abnormal temperature changes or smoke formation within the room, providing early warning of a fire. Furthermore, the fire detection module 10 is electrically connected to a controller, ensuring real-time and accurate information transmission. Upon detecting signs of fire, the fire detection module 10 immediately sends a signal to the controller, activating the emergency response of the entire fire extinguishing system. Specifically, when the fire detection module 10 detects abnormal indicators, such as smoke particles in the air exceeding a safety threshold or a rapid increase in the room's temperature, it transmits this information to the controller. The controller then analyzes these signals and, based on pre-set procedures, determines the next course of action, such as activating the fire extinguishing mechanism or issuing an audible and visual alarm.

[0033] The inverter room is divided into multiple independent spaces, each with a specific purpose and equipment, potentially including different types of electrical equipment and inverters. Given this layout, a fire detection module 10 is preferably installed in each independent space. Each fire detection module 10 installed in each independent space can monitor environmental changes and potential fire risks in a specific area. For example, if equipment in a particular area overheats or experiences an electrical malfunction (such as rising temperatures or increasing smoke), the corresponding fire detection module 10 can immediately detect the abnormal indicators. Furthermore, considering that different spaces in the inverter room may have different environmental conditions and fire risks due to their layout or the equipment stored, each fire detection module 10 is calibrated to suit the specific conditions of its area. For example, a space storing batteries or inverters may require a more sensitive heat sensor, while a poorly ventilated area may require a detector more sensitive to smoke. The independent operation of each module ensures that localized issues can be quickly identified and addressed without affecting other areas. This localized monitoring approach not only improves the accuracy and efficiency of fire warnings, but also reduces the possibility of false alarms. For example, in non-fire situations, heat or smoke generated by certain tasks or equipment will not cause the fire suppression system in the entire inverter room to malfunction. This ensures that, in the event of a fire, rapid and targeted firefighting actions can be implemented, minimizing potential damage and losses. In summary, the fire detection modules 10 installed in each independent space not only improve the fire monitoring coverage of the entire inverter room, but also enhance its adaptability and responsiveness to diverse environmental conditions and potential risks.

[0034] The fire extinguishing mechanism includes a carbon dioxide storage device 21 and a gas transport pipeline. The synergistic effect of the two ensures the high efficiency and safety of the fire extinguishing process. Carbon dioxide is a highly efficient fire extinguishing medium, and it is safe and harmless to electrical equipment because it will not cause short circuits or damage to electrical equipment. The input end of the gas transport pipeline is connected to the carbon dioxide storage device 21, and the output end is connected to the box inverter room. Among them, the gas transport pipeline is a channel connecting the carbon dioxide storage device 21 and the box inverter room to ensure that carbon dioxide can be quickly transported to the box inverter room. The input end of the gas transport pipeline is directly connected to the carbon dioxide storage device 21, and the output end is open to the area of ​​the box inverter room. This ensures that the entire box inverter room can be effectively protected. Furthermore, each box inverter room is equipped with at least one output end of a gas transport pipeline. That is, each room is equipped with at least one output end of a gas transport pipeline.

[0035] On this basis, the gas transport pipeline comprises a main transport route 221 and multiple branch transport routes 222. The input of the main transport route 221 is connected to the carbon dioxide storage device 21. This direct connection ensures that large quantities of carbon dioxide can be quickly released from the storage device in the event of a fire. The input of each branch transport route 222 is connected to the output of the main transport route 221, and the output of each branch transport route 222 is connected to the inverter room. Multiple branch transport routes 222 extending from the main transport route 221 are responsible for transporting carbon dioxide from the main route to each independent space in the inverter room. The input of each branch transport route is connected to the output of the main transport route 221, and the output leads directly to the corresponding independent space. In the event of a fire, a rapid response can be initiated to the specific fire location, accurately delivering fire extinguishing agent to the required area. To ensure the effectiveness and coverage of the system, at least one branch transport route 222 is assigned to each independent space in the inverter room. This not only ensures that each space receives a timely supply of fire extinguishing agent, but also improves the adaptability and responsiveness of the entire fire extinguishing system to different fire scenarios. In summary, the installation of gas pipelines improves the efficiency and reliability of the fire extinguishing system. This ensures that even within the complex structure of a box-type inverter room, each independent space can receive prompt and effective fire extinguishing action in the event of a fire, effectively controlling the fire and safeguarding the safety of the box-type inverter room, the equipment within it, and the personnel.

[0036] In one specific embodiment, each transport branch 222 is equipped with a solenoid valve 223, which is electrically connected to a controller. The primary function of the solenoid valves 223 is to control the flow of carbon dioxide gas. They can be rapidly opened or closed based on signals from the controller, ensuring that carbon dioxide is released only to the appropriate areas when needed, thereby improving the efficiency of the fire extinguishing system. For example, if the fire detection module 10 in a separate space detects signs of fire, the controller will immediately send a signal to the solenoid valve 223 in the corresponding space, instructing it to open, allowing carbon dioxide to flow into that area for extinguishing the fire. This automated control improves fire extinguishing response speed and efficiency. The solenoid valves 223 operate stably under high pressure and long-term use, and are highly resistant to environmental changes (such as temperature fluctuations or vibration). Furthermore, to address emergencies or control system failures, the solenoid valves 223 are typically designed with a manual override function, allowing for manual control when needed, providing an additional layer of safety.

[0037] Next, a pressure monitoring sensor 211 is installed on the carbon dioxide storage device 21 to monitor the pressure of the stored carbon dioxide in real time. The pressure monitoring sensor 211 is electrically connected to the controller. This monitoring ensures that the available carbon dioxide can be quickly detected in the event of a fire, ensuring smooth firefighting operations. Furthermore, the connection to the controller enables an immediate alarm to be issued if abnormal pressure is detected in the carbon dioxide storage device 21, ensuring the maintenance and safety of the fire extinguishing system. Both the environmental monitoring module 50 and the alarm module 40 are electrically connected to the controller. The environmental monitoring module 50 is installed on the inner wall of the inverter room to continuously monitor the indoor environmental conditions. The environmental monitoring module 50 typically includes multiple sensors that work together to provide comprehensive, real-time monitoring of the environment within the inverter room. The alarm module 40 provides an alarm when a fire or other dangerous situation is detected. The alarm module 40 may include various warning devices to alert on-site personnel to take timely countermeasures and indicate safe evacuation routes. A remote communication module is installed at the output of the controller. The remote communication module transmits environmental monitoring and fire detection data to a remote terminal, such as a central control room or mobile device. Through the remote communication module, system administrators can obtain real-time information about the environment and safety status of the inverter room, allowing for effective monitoring and management even when not on site. This not only improves the convenience and efficiency of monitoring, but also increases response speed.

[0038] Preferably, the alarm module 40 includes a plurality of buzzers and warning lights. When the buzzer detects signs of fire, such as smoke or abnormal temperature, it will attract the attention of personnel by emitting a continuous high-decibel sound. The alarm sound of the buzzer is intended to indicate an emergency situation and prompt personnel to take action, such as evacuating quickly or performing other safety procedures. The warning light provides a visual warning by emitting a strong light signal. These warning lights usually operate in a flashing mode to increase the probability of being noticed. The light signal not only assists the sound alarm, but also provides an effective warning in a noisy environment, ensuring that everyone is aware of the emergency and responds in time. Through the effective combination of the buzzer and the warning light, a dual warning mechanism is provided, which greatly enhances the safety notification effect in an emergency situation, ensures the safety of personnel in the inverter room and the timely response to the fire.

[0039] In one specific embodiment, the environmental monitoring module 50 includes a temperature and humidity sensor, an oxygen content sensor, and a hazardous gas detection sensor. The temperature and humidity sensor monitors the temperature and humidity levels in the room in real time. In a photovoltaic power plant, inverters and other electrical equipment may experience performance degradation or damage due to high temperatures or abnormal humidity. Therefore, the temperature and humidity sensor can identify equipment overheating or abnormal humidity early, thereby preventing the risk of fire. The oxygen content sensor measures the oxygen content in the environment to indicate whether the oxygen level in the space has decreased during a fire and carbon dioxide is used to extinguish the fire. The hazardous gas detection sensor monitors the presence of potentially hazardous gases in the air, such as carbon monoxide or other gases generated by electrical problems and equipment failures. These gases may be released in the early stages of a fire or due to equipment failure. The temperature and humidity sensor, oxygen content sensor, and hazardous gas detection sensor are all installed on the inner wall of the inverter room, continuously monitoring key environmental indicators within the room to ensure timely detection of any abnormal conditions that could cause a fire. The temperature and humidity sensors, oxygen content detection sensors, and harmful gas detection sensors are all electrically connected to the controller. The detection data from these sensors is transmitted to a remote terminal via a remote communication module. The data collected by the temperature and humidity sensors, oxygen content detection sensors, and harmful gas detection sensors is transmitted to the controller in real time. The controller analyzes this data to determine whether there are any abnormal conditions, such as excessively high temperatures or elevated concentrations of harmful gases, which could indicate a risk of fire. Once such conditions are detected, the controller can immediately take action, such as activating a fire extinguishing mechanism or sounding an alarm. Furthermore, through the remote communication module, the data from the environmental detection module 50 is not limited to local use. It can also be sent to remote terminals, such as a central control room or mobile devices, allowing operations and maintenance personnel to monitor the environmental conditions of the inverter room from a distance, even when they are not on site. This function also enables timely response to potential fire threats, maintains the operating status of equipment, and ensures the safe operation of the entire photovoltaic power station.

[0040] Preferably, the hazardous gas detection sensor includes a carbon monoxide (CO) sensor. Carbon monoxide is an early indicator of combustion, providing a timely alarm at the onset of a fire and buying valuable time for firefighting operations. The CO sensor detects CO concentrations in the air and immediately transmits this information to a controller if it detects concentrations exceeding a safety threshold. Upon receiving data from the CO sensor, the controller will respond accordingly, potentially activating the fire suppression system or initiating emergency notification procedures. The CO sensor is also connected to a remote communication module. This means that if abnormal CO concentrations are detected, this information can be transmitted in real time to a remote terminal, such as a central control room or mobile device, allowing the operations and maintenance team to gain real-time insight and, if necessary, remotely intervene. Furthermore, a CO sensor can also be provided. Both the CO and CO sensors transmit their respective gas levels to a remote terminal via the remote communication module. This allows maintenance personnel or rescue workers to implement appropriate rescue strategies based on the CO and CO levels. The application of carbon monoxide content detection sensors not only enhances the early identification capability of potential fires, but also improves the response efficiency and safety performance of the entire fire extinguishing system, ensuring the comprehensive protection of the box inverter room and its internal equipment.

[0041] In addition to carbon dioxide fire extinguishing, the fire extinguishing mechanism also includes a dry powder spraying device in the fire extinguishing system. Dry powder is used as a fire extinguishing medium. It can quickly cover the flames and block oxygen without causing damage to electrical equipment. Specifically, the dry powder spraying device includes a plurality of dry powder nozzles 61 distributed in various areas of the box inverter room, and the dry powder nozzles 61 are set toward the equipment in the box inverter room, such as the electrical panel and inverter. This positioning strategy ensures that once a fire is detected, the nozzles 61 can spray dry powder directly onto the fire source, thereby quickly extinguishing the flames. The dry powder spraying device is electrically connected to the controller. It is automatically activated when a fire is detected. Based on the data from the fire detection module 10, the controller can decide whether to activate the dry powder spraying device and which specific dry powder nozzles 61 should be activated. This control not only improves the efficiency and speed of fire extinguishing, but also reduces the extra cleanup work that may be caused by unnecessary use of dry powder.

[0042] To enhance the ability to detect early signs of fire, a smoke detection sensor is also provided. It is electrically connected to the controller and, through the controller, to the alarm module 40. The smoke detection sensor can sense the initial signs of smoke, which is often the first obvious sign of a fire. The smoke detection sensor is installed within the inverter room to ensure full coverage and promptly detect the presence of smoke. Upon receiving the signal from the smoke detection sensor, the controller quickly analyzes it and determines whether to activate the fire extinguishing system or other emergency response measures. This ensures swift action in the early stages of a fire, effectively mitigating potential damage. Furthermore, the controller is connected to the alarm module 40. Upon detecting smoke, the alarm module 40 is activated, emitting audible and visual signals to warn personnel within the inverter room and instruct them to take appropriate safety measures. This combination of smoke detection sensors, the controller, and the alarm module 40 not only speeds up fire detection and response, but also enhances the safety of the entire fire extinguishing system. Through real-time monitoring and an automated response process, the inverter room is provided with comprehensive fire protection, ensuring the safe operation and equipment integrity of the photovoltaic power station.

[0043] Furthermore, flow sensors 224 are installed at the output ports of the main transport route 221 and each branch transport route 222. Flow sensors 224 can measure the amount of carbon dioxide gas passing through the pipeline in real time, providing the controller with real-time data on the rate and total amount of carbon dioxide released. This data ensures that sufficient carbon dioxide is delivered to the fire source during the fire extinguishing process, while avoiding unnecessary waste or potential safety risks caused by excessive carbon dioxide release. In particular, during a fire, the controller can use the information provided by flow sensors 224 to adjust the carbon dioxide flow rate to adapt to different fire scenarios. For example, if a fire in a certain area requires more carbon dioxide to extinguish, the controller can adjust the flow rate of the corresponding branch to ensure a quick and effective response to the fire. Conversely, if excessive flow is detected, it may indicate a system leak or other problem. The controller can take measures, such as closing valves in the corresponding area, to avoid unnecessary waste of resources or potential safety risks. As can be seen, flow sensors 224 not only make the fire extinguishing system more responsive, but also improve the reliability and maintenance convenience of the entire fire extinguishing system. It should be noted here that all the sensors mentioned above, such as temperature and humidity sensors, oxygen content detection sensors and carbon monoxide content detection sensors, etc., are existing sensors. Their main purpose is to monitor relevant information, and their connection with the controller adopts existing feasible connection technologies and methods, which will not be repeated here.

[0044] This application achieves more comprehensive early detection of fires and improves the ability to respond to potential fires in a timely manner by installing a fire detection module 10 in each independent space of the box inverter room. The use of a carbon dioxide storage device 21 and a gas transport pipeline ensures rapid and effective delivery of fire extinguishing media, improving the efficiency and speed of fire extinguishing. The smoke detection sensor can quickly identify dangers in the early stages of a fire, enhancing the overall safety monitoring capability. By deploying flow sensors 224 on the gas transport pipeline, the effect of accurately controlling the carbon dioxide flow is achieved, optimizing resource utilization. The environmental detection module 50 provides comprehensive environmental monitoring and enhances adaptability to complex working environments. The remote communication module can promptly transmit key information to the remote control center, providing support for remote monitoring and timely intervention, and enhancing the flexibility and emergency management capabilities of the fire extinguishing system.

[0045] The workflow of the fire extinguishing system is further explained below. During routine operation, the environmental monitoring module 50 continuously monitors the temperature, humidity, and hazardous gas levels within the inverter room, while the smoke detection sensor monitors smoke in the air. When one of these sensors detects a potential fire sign, such as an abnormally elevated temperature, hazardous gas concentration, or smoke, it immediately sends a corresponding signal to the controller. Upon receiving these signals, the controller first activates the alarm module 40, which then emits an audible and visual alarm, alerting occupants of the emergency and directing them to evacuate safely. The controller then determines whether to activate the fire extinguishing mechanism based on the severity and location of the fire. If so, the controller opens the corresponding solenoid valve 223 connected to the carbon dioxide storage device 21, allowing carbon dioxide to flow through the main and branch gas transport pipelines to the area where the fire has been detected. A flow sensor 224 monitors this process, ensuring that the carbon dioxide is delivered to the target area at the appropriate flow rate and speed. In some cases, the dry powder spraying system may also be activated as a supplementary fire extinguishing measure, particularly when carbon dioxide may not be sufficient for large fires. The dry powder nozzle 61 sprays dry powder directly at the fire source, further ensuring rapid extinguishing. Throughout the firefighting process, the remote communication module transmits real-time data and status updates to the remote control center. This allows the operations team to monitor the fire situation from a remote location and intervene when necessary. This overall workflow constitutes a specific implementation of the firefighting system, enabling not only a rapid response to fires but also adapting firefighting strategies to varying circumstances, thereby maximizing the safety of the inverter room and the equipment within.
