Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle charging safety technology, and specifically to an intelligent automatic fire extinguishing method and system for new energy vehicle charging stations, which aims to improve the safety of the new energy vehicle charging process and reduce fire accidents and economic losses caused by charging. Background Art

[0002] With the rapid development of the new energy vehicle industry, the safety of charging stations, as key facilities for the energy supply of new energy vehicles, has received increasing attention. In order to improve the safety performance of charging stations, intelligent automatic fire extinguishing systems have emerged. The system integrates advanced fire detection, intelligent control, efficient fire extinguishing and remote monitoring and management technologies, aiming to achieve rapid response and effective control of charging station fires.

[0003] At present, the intelligent automatic fire extinguishing system for charging new energy vehicles has made some progress. For example, some systems use advanced sensor technology to monitor the smoke, temperature, flame and other fire parameters in the charging station in real time. Once an abnormal situation is found, the system will immediately start the alarm program and send an alarm message to the remote monitoring management platform. At the same time, the system is also equipped with efficient and environmentally friendly fire extinguishing devices, such as dry powder fire extinguishers and gas fire extinguishers. These fire extinguishing devices can be quickly activated and accurately extinguished according to the type and size of the fire.

[0004] In addition, some intelligent automatic fire extinguishing systems also have remote monitoring and management functions, and users can view the status of the charging station, the operation of the fire extinguishing device, and the record of alarm information in real time through mobile phone APP, computer and other terminals. This not only improves the convenience and practicality of the system, but also helps managers to discover and deal with potential safety hazards in a timely manner.

[0005] Although the existing intelligent automatic fire extinguishing system for new energy vehicle charging has achieved certain results, there are still some shortcomings:

[0006] The accuracy and timeliness of fire detection need to be improved: Although the existing system uses advanced sensor technology, the performance of the sensor may be affected in certain complex environments, such as high temperature, high humidity, extreme cold, etc., resulting in a decrease in the accuracy and timeliness of fire detection.

[0007] Insufficient adaptability and flexibility of fire extinguishing devices: Different types of fires require different fire extinguishing methods and extinguishing agents. However, existing fire extinguishing devices can often only extinguish specific types of fires and lack adaptability and flexibility. In addition, some fire extinguishing devices take a long time to extinguish the fire after being activated, which may cause greater losses to personnel and property.

[0008] System reliability and stability need to be improved: The intelligent automatic fire extinguishing system is a complex system involving multiple components and modules. Therefore, the reliability and stability of the system are crucial to ensure the safety of charging stations. However, the existing system may fail or degrade in performance during long-term operation, which may affect the fire extinguishing effect and safety of the system.

[0009] Insufficient convenience for user operation and maintenance: Although the existing systems provide remote monitoring and management functions, there are still some deficiencies in user operation and maintenance. For example, the operation interface of some systems is not intuitive and easy to use, which makes it difficult for users to quickly get started; at the same time, the maintenance process of some systems is also cumbersome and requires regular maintenance and maintenance by professionals.

[0010] In summary, although the intelligent automatic fire extinguishing method and system for charging new energy vehicles have made certain progress, they still need to be improved and perfected in terms of fire detection, fire extinguishing equipment, system reliability and stability, and user operation and maintenance convenience. Summary of the invention

[0011] The present invention aims to provide an intelligent automatic fire extinguishing method and system for charging new energy vehicles. Through multiple stages such as real-time monitoring, early warning, initial fire extinguishing, linked fire extinguishing and remote manual control, the present invention aims to solve the problem of lack of effective fire-fighting measures in existing new energy vehicle charging stations, ensure that new energy vehicle users can charge safely, and reduce the occurrence of charging fire accidents.

[0012] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0013] An intelligent automatic fire extinguishing method for charging new energy vehicles comprises the following steps:

[0014] a) Monitoring phase:

[0015] Use smoke detectors and flame detectors installed at new energy vehicle charging stations to monitor smoke and flame conditions in the charging area in real time;

[0016] When smoke or flame is detected, a linkage response is made respectively;

[0017] The power supply of the intelligent fire monitoring system comes from the main power supply of the charging station, and is equipped with a backup power supply. When the charging station starts to supply power, the monitoring system enters the working state without additional triggering. The backup power supply is used to keep the monitoring system running continuously when the main power supply fails. That is, the power of the monitoring system is provided by the charging station, including normal power supply and backup power supply, to ensure that the system can maintain the monitoring state under any circumstances.

[0018] b) Early warning stage:

[0019] When the smoke detector or flame detector detects an abnormal signal, the smoke control unit immediately triggers the alarm system, emits an audible and visual alarm signal, and sends an alarm text message and calls the alarm phone number of the preset manager;

[0020] At the same time, the video surveillance system obtains real-time images of the fire scene so that management personnel can remotely judge the fire situation;

[0021] c) Initial fire extinguishing stage:

[0022] If the fire is in the early stages, the battery will emit a lot of heat. When the temperature of the dry powder fire extinguisher and sprinkler head in the pit where the new energy vehicle battery is located reaches 68 degrees, the pit water sprinkler system and dry powder fire extinguisher will be turned on to quickly extinguish the fire.

[0023] When the pit fire extinguisher and sprinkler cannot control the fire, and flames are generated, when the parking flame camera and the flame cameras on the left and right ends of the ceiling detect the flames, the linkage control system will open the fire curtain and automatically lower it to isolate the burning vehicle from adjacent vehicles to prevent the fire from spreading and injuring adjacent vehicles;

[0024] d) Linked fire extinguishing stage:

[0025] If the pit fire extinguishing system cannot effectively control the fire, the flame camera of the linkage system will detect the flame and further activate the dry powder fire extinguisher on the roof for linkage fire extinguishing;

[0026] At the same time, the water circuit switch is opened for the rapid start of the subsequent linkage spray system through the electric blasting spray glass thermostat;

[0027] e) Remote manual control stage:

[0028] The manager can use a mobile phone or on-site control terminal to manually move the fire extinguisher in the adjacent parking space to the fire source for multiple fire extinguishing operations;

[0029] If the fire cannot be extinguished after multiple dry powder extinguishing, the manager can remotely open the solenoid valve and start the pipeline booster pump, and use the sprinkler system to extinguish the fire from both the bottom pit and the top;

[0030] f) Leakage disconnection stage:

[0031] During the fire extinguishing process, when the temperature-sensitive glass beads explode, the heating wire contacts the metal casing of the fire extinguisher, causing leakage. The leakage protection switch of the control box automatically disconnects the power supply to ensure the safety of personnel.

[0032] An intelligent automatic fire extinguishing system for charging new energy vehicles, comprising:

[0033] a) Monitoring device: including smoke detectors and flame detectors, used to monitor smoke and flame conditions in the charging area in real time;

[0034] b) Linkage device: used to automatically start the smoke exhaust fans and dry powder fire extinguishing devices at both ends of the charging shed in response to smoke and flame conditions;

[0035] c) Alarm system: including sound and light alarm, SMS alarm module and telephone alarm module, used to send alarm signals when a fire occurs and send alarm information to management personnel;

[0036] d) Initial fire extinguishing equipment: including dry powder fire extinguishers and water sprinkler systems in the pit, used for rapid fire extinguishing in the early stages of a fire;

[0037] e) Linked fire extinguishing device: including dry powder fire extinguishers and sprinkler systems on the roof and bottom of the vehicle, as well as fireproof curtains and electric blasting sprinkler glass thermostats, which are used for linked fire extinguishing when the fire cannot be controlled by the initial fire extinguishing device;

[0038] f) Remote manual control device: including mobile control terminal and on-site control terminal, which is used by managers to remotely and manually control the fire extinguishing system, move nearby fire extinguishers to the fire source and start fire extinguishing;

[0039] g) Leakage disconnect device: It is used to automatically disconnect the power supply to ensure the safety of personnel during the fire extinguishing process when the temperature-sensitive glass beads explode and the heating wire contacts the metal casing of the fire extinguisher.

[0040] Furthermore, it also includes:

[0041] Video surveillance system: used to obtain real-time images of the fire scene so that managers can remotely judge the fire situation;

[0042] Fire cabinet: It is set up at the charging station site and equipped with two-person firefighting equipment and tools for management personnel to handle on-site situations;

[0043] Fire emergency lighting and escape direction signs: When the on-site power supply is cut off, emergency lighting provides on-site rescue lighting and indicates the direction of escape to avoid disaster relief without light.

[0044] Training and instruction module: Provides training and instruction materials to ensure that managers can skillfully use fire-fighting systems and equipment for emergency response.

[0045] Beneficial effects of the present invention:

[0046] 1. Significantly improve safety and emergency response speed

[0047] By integrating highly sensitive smoke detectors, flame detectors and temperature sensors, the intelligent automatic fire extinguishing system can monitor the environmental parameters in the charging station in real time. Once the initial signs of fire are detected, the early warning mechanism is immediately triggered and the fire extinguishing process is automatically started. This instant response capability greatly shortens the time from fire discovery to control, effectively curbs the spread of fire, and significantly improves the safety of charging stations.

[0048] 2. Multi-level fire extinguishing mechanism enhances fire extinguishing effect

[0049] The system adopts a multi-level fire extinguishing mechanism, including initial fire extinguishing and linkage fire extinguishing, and forms a three-dimensional defense system through various fire extinguishing means such as pit dry powder fire extinguishers, water sprinkler systems, roof / underbody dry powder fire extinguishers, etc. This multi-level, all-round fire extinguishing strategy can provide targeted fire extinguishing solutions for different fire source types and fire sizes, thereby enhancing the fire extinguishing effect and reducing the losses caused by fire.

[0050] 3. Remote manual control and monitoring functions improve flexibility

[0051] The system provides remote manual control and monitoring functions. Managers can remotely monitor the status of the charging station anytime and anywhere through the mobile phone APP or on-site control panel, and manually activate the fire extinguishing equipment when necessary. This design not only enhances the flexibility of the system, but also enables managers to respond quickly in emergency situations and effectively deal with emergencies such as fires.

[0052] 4. Optimize resource utilization and reduce maintenance costs

[0053] The intelligent automatic fire extinguishing system can automatically identify fire risks and formulate fire extinguishing strategies according to risk levels through data analysis and decision-making functions. This intelligent management method not only optimizes the use of fire extinguishing resources and avoids unnecessary waste, but also reduces the maintenance cost of the system. At the same time, the system also has self-diagnosis and alarm functions, which can detect and handle equipment failures in a timely manner to ensure that the system is always in the best working condition.

[0054] 5. Improve the safety management level of the new energy vehicle industry

[0055] The implementation of this intelligent automatic fire extinguishing method and system not only improves the safety management level of charging stations, but also sets an example for the overall safety management of the new energy vehicle industry. Through the demonstration effect and technology promotion, it will drive the progress of the entire new energy vehicle industry in safety management and promote the industry to develop in a safer, more reliable and efficient direction.

[0056] In summary, an intelligent automatic fire extinguishing method and system for charging new energy vehicles has multiple beneficial effects, including significantly improving safety and emergency response speed, enhancing fire extinguishing effect, improving flexibility, optimizing resource utilization and reducing maintenance costs, and improving the safety management level of the new energy vehicle industry. These effects work together to ensure the safety management of charging stations, providing a strong guarantee for the popularization and development of new energy vehicles.

[0108] Specific application examples:

[0109] 1. Building Description

[0110] 1. Based on the fact that there are no fire-fighting measures in social new energy vehicle charging stations, it is designed to ensure that new energy vehicle users can charge and use new energy vehicles safely, reduce the occurrence of charging fire accidents, and avoid property and economic losses caused by charging.

[0111] 2. This automatic fire-fighting design for new energy vehicles adopts two technologies: an intelligent fire-fighting method for electric vehicle charging stations and a fire-fighting method for electric vehicles to extinguish multiple fires at one time, so as to prevent the occurrence of charging fire accidents for new energy vehicles and avoid the huge economic losses and even life losses caused by charging accidents.

[0112] 3. The design uses 6mm thick steel plates combined with welded steel frames, and 100*100*2 square steels as purlins, and rock wool fireproof insulation boards and glass-shaped color steel tile roof panels to achieve the purpose of charging, heat insulation and cooling. The square steel and roof frame are connected by welding or bolts.

[0113] 4. Steel column foundation 900*900*1000 reinforced concrete, embedded with 12mm thick steel plate, The steel bars are pre-buried and the embedding depth in concrete is not less than 600, and the concrete strength grade is C30.

[0114] 5. The bodies of new energy electric vehicles are separated by linked fire-proof curtains to protect neighboring vehicles from damage when an accidental fire occurs in one vehicle.

[0115] 6. The steel body of the scaffolding is painted with fire-retardant paint to meet the requirements of fire resistance and anti-corrosion.

[0116] 2. Firefighting instructions

[0117] 1. The building uses A-grade high-temperature resistant fiberglass smoke curtains, roof rock wool insulation and cooling, and metal square steel fire retardant paint protection.

[0118] 2. Set up the industry smoke and flame alarm push information and telephone dialing intelligent alarm system, and install automatic fire extinguishing and one-fire-multiple-extinguishing intelligent system functions.

[0119] 3. When a hot car that has been running for a long time without equipment control is immediately charged, the battery is prone to spontaneous combustion and explosion. First, a large amount of smoke is generated before the battery spontaneously ignites. The dense smoke is sensed by the smoke detector in the smoke gathering area of ​​the charging station, and the alarm is sounded through the alarm of the equipment. At the same time, the alarm phone number and information are pushed to the manager (10 management phone numbers can be pre-stored), prompting the manager to deal with the dangerous situation.

[0120] 4. If the manager has not arrived at the scene, the danger will gradually increase, and the temperature will continue to rise to the ignition temperature, causing flames. The batteries installed on the new energy chassis will generate a lot of heat to burn. When the temperature reaches 68°C, the dry powder fire extinguisher and water sprinkler in the pit will be turned on. The opened dry powder fire extinguisher will block the air at the source of the fire, so that the flammable point lacks the necessary and sufficient combustion conditions, and the generation of the fire source is controlled;

[0121] Secondly, the water is sprayed to the fire source to cool it down and control the temperature to extinguish the fire, thus eliminating the fire source in its infancy; if the temperature rises too quickly, the bottom pit fire extinguishing cannot control the occurrence of the fire, and the flame rises to the car body, the flame monitoring camera will quickly start the linkage system to quickly heat the heating wire to open the fire extinguisher and quickly extinguish the fire with dry powder on the roof. At this time, the linked fire-proof curtain will be powered on and heated to melt the binding materials of the curtain, and the curtain will sag under the action of its own weight, and the curtain will surround the burning vehicle and isolate it from the fire source of adjacent vehicles to protect it from harm; at the same time, the electric blasting spray glass Thermostat, alarm horn starts to power on the remote control switch and enter the online state. The management personnel can turn on the mobile phone remote switch to move the hanging fire extinguisher to the fire source multiple times, and remotely and manually move the dry powder fire extinguisher to the fire source for multiple fire extinguishing disposals, so as to put out the fire and control the fire. Finally, the pipeline booster pump and solenoid valve can be manually opened to extinguish the fire with spraying, which completely avoids the property loss caused by charging. After the temperature-sensitive glass beads explode, the heating wire will contact the metal casing of the fire extinguisher, and the power supply is connected to the ground through the steel frame, resulting in leakage and disconnection of the power supply.

[0122] Fire prevention measures for this system:

[0123] 1. Fire retardant coating for steel frame;

[0124] 2. Roof insulation and cooling;

[0125] 3. Fireproof curtains to block fire;

[0126] 4. Dry powder fire extinguishing in pits without oxygen;

[0127] 5. Pit fire sprinkler;

[0128] 6. Top electronically controlled spray of dry powder automatically extinguishes fire when oxygen is cut off;

[0129] 7. The mobile top electronically controlled spray dry powder can extinguish multiple fires when oxygen is cut off;

[0130] 8. Electric explosion and double spray water fire extinguishing;

[0131] 9. Manual fire extinguishing. three,

[0133] New energy vehicles have a canopy and the battery also has a protective structure. Any form of fire extinguishing cannot enter the fire source. An effective way is to set up an automatic curtain through the intelligent linkage system. When the system detects a flame alarm, the intelligent linkage system will electronically control it to freely droop and separate it from adjacent vehicles to prevent the fire from burning other vehicles; secondly, to control the development of the fire, the intelligent linkage system automatically starts the dry powder fire extinguisher and sprinkler water fire extinguishing installed on the roof and under the vehicle to carry out initial fire extinguishing, control the development of the fire and extinguish the fire.

[0134] IV. Conclusion

[0135] This implementation plan takes into account the safety needs of new energy vehicle charging stations and designs an intelligent automatic fire extinguishing system that integrates monitoring and early warning, multi-level fire extinguishing, remote manual control and safety protection. The implementation of this system will significantly improve the safety management level of charging stations and provide strong guarantees for the healthy development of the new energy vehicle industry.

[0136] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
