Description

Technical Field

[0001] This application relates to the field of container technology, and in particular to a fire extinguishing device for containers with non-pressurized temperature sensing. Background Technology

[0002] With the rapid development of the new energy industry, containerized battery storage and charging devices are widely used in battery swapping stations, energy storage stations and other scenarios due to their flexible deployment and high mobility. However, the closed nature of the container and the dense storage of batteries make it face a high risk of thermal runaway and fire. Once a fire occurs, if it is not dealt with in time, it can easily cause large-scale property damage or even safety accidents. Therefore, a supporting efficient fire protection system has become a core requirement.

[0003] Existing traditional fire extinguishing systems have slow response speeds, low fire extinguishing efficiency, and unreasonable sprinkler point layouts, which can easily lead to blind spots in protection. They also lack the ability to monitor and handle internal gas concentrations in real time and cannot cut off the circuit in time when gas leaks or concentrations exceed the standard, posing safety hazards. In addition, they lack gas purification functions, and the harmful gases remaining after a fire can easily cause secondary harm to equipment and personnel. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing traditional fire extinguishing systems, such as slow response speed, low fire extinguishing efficiency, unreasonable sprinkler point layout leading to blind spots, lack of real-time monitoring and handling of internal gas concentration exceeding standards, inability to cut off circuits in time when gas leaks or concentrations exceed standards, posing safety hazards, and lack of gas purification function, which can easily cause secondary harm to equipment and personnel due to residual harmful gases after a fire. Therefore, this invention proposes a fire extinguishing device for containers with non-pressurized temperature sensing.

[0005] The fire extinguishing device for containers with non-pressurized temperature sensing provided in this application adopts the following technical solution: A fire extinguishing device for containers with non-pressurized temperature sensing, comprising: The entire unit and the shelving set up inside it; the entire unit has internal charging interfaces and matching charging plugs; Multiple batteries were placed on the shelf; The automatic fire extinguishing system is installed inside the whole system and achieves rapid fire identification and automatic fire extinguishing based on the non-pressurized temperature sensing triggering principle; The exhaust ventilation system is installed inside the entire structure to regulate the airflow within the structure in real time. The lighting system, installed inside the entire system, provides sufficient and stable lighting support for equipment maintenance, battery upkeep, emergency response, and other operations within the system. An explosion-proof control and autonomous alarm system is installed inside the entire system to monitor and provide graded alarms for dangerous signals such as smoke, combustible gas, and ambient temperature in real time. The remote-controlled air conditioning cooling system is installed inside the entire system and can achieve precise control of the overall internal temperature through a remote terminal.

[0006] Furthermore, a charger is fixedly installed on the left side of the shelf.

[0007] Furthermore, the automatic fire extinguishing system includes multiple temperature-sensing magnetic power generation devices installed on the top side of the interior of the system. Multiple nozzle ends are fixedly installed on both the left and right ends of the top side of the interior of the system. Multiple sprinkler points are placed inside the system to achieve fire protection without blind spots. A gas sensing system is also installed inside the system. Multiple electric initiator linkage data cable ends are fixedly installed on both the left and right ends of the top side of the interior of the system.

[0008] Furthermore, the temperature-sensing magnetic power generation device is electrically connected to the data line terminal of the electric initiator, and the data line terminal of the electric initiator is signal-linked with the nozzle terminal.

[0009] Furthermore, the explosion-proof control and autonomous alarm system includes a smoke detector, a manual alarm button, an audible and visual alarm, an alarm linkage controller, a combustible gas detector, and emergency lighting. The charging compartment is equipped with an aerosol fire extinguishing device.

[0010] Furthermore, the exhaust ventilation system can actively control the flow rate and direction of the overall internal air, and the exhaust volume of the exhaust ventilation system reaches no less than the actual air volume of the cabin per minute, ensuring that the internal gas is quickly replaced.

[0011] Furthermore, the automatic fire extinguishing system includes smoke detectors, heat detectors, fire detection probes, and an alarm system; a water-based fire extinguisher is installed on the top of the entire system. The water-based fire extinguisher should possess the following characteristics: all-around effective fire extinguishing, fluoride-free, environmentally friendly and non-toxic, rapid cooling, heat insulation and flame retardant to prevent reignition, and international certification. It can be sprayed on people to aid escape. After its expiration date, it will naturally degrade and can be used as fertilizer without special treatment. Furthermore, the lighting system includes main lights and emergency lights, and the piping, wiring, and the system itself are explosion-proof.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution uses a non-pressurized, temperature-sensing, magnetic fire detection and extinguishing device, which requires no additional power supply, contact springs, or conventional smoke and temperature-sensing fire detectors. It also eliminates the need for complex equipment and wiring, integrating alarm and fire extinguishing functions, thus significantly reducing engineering construction and maintenance costs. At the same time, the extinguishing agent perfluorohexanone is highly environmentally friendly, causing no harm to humans or goods inside containers, making it suitable for container transportation and application scenarios, and combining economy and safety. 2. This solution, through the design of rotating 180 degrees and reinstalling each nozzle end and electric initiator wire inlet after installation, effectively ensures the uniformity of fire extinguishing agent spraying and improves the comprehensiveness and effectiveness of fire response. 3. This solution uses thermal induction wires to connect all fire extinguishing devices in series. When a fire occurs in the protected area, all fire extinguishing devices can be fired almost simultaneously, which can quickly control the fire in the early stage of the fire, minimize the loss of goods, and greatly improve the fire extinguishing efficiency and protection effect. 4. This solution precisely designs the clamp installation position, offsetting it 850mm from the center of the container to both sides. Each device is equipped with 3 clamps, and the fire-fighting equipment is installed inside the U-shaped wall panel on the top of the container. This ensures the stability of the installation, does not occupy the effective space inside the container, does not affect the utilization rate of the container size, and adapts to the spatial layout requirements of the container.

[0013] This invention deploys multiple spray points inside the energy storage container to achieve comprehensive fire protection coverage. The supporting fire terminal system integrates temperature and smoke detection, and adds a gas sensing system to detect gas concentration in real time. When the concentration exceeds the standard, the circuit is automatically cut off, greatly improving safety. At the same time, it has a gas purification function, which can effectively remove harmful gases remaining after a fire, further ensuring the safety of equipment and personnel. The overall system has high fire extinguishing efficiency and comprehensive protection, and is suitable for the high safety requirements of container energy storage scenarios.

[0019] Reference Figure 3The automatic fire extinguishing system 7 includes multiple temperature-sensing magnetic power generation devices 4 installed on the top side inside the whole 1. Multiple nozzle ends 3 are fixedly installed on both the left and right ends of the top side inside the whole 1. Multiple sprinkler points are placed inside the whole 1 to achieve fire protection without blind spots. The whole 1 is also equipped with a fire terminal system to control the internal temperature and smoke sensors. The whole 1 is also equipped with a gas sensing system that can detect whether the gas concentration in the internal space exceeds the standard. If it exceeds the critical value, the circuit switch will be disconnected to increase safety. Multiple electric initiator linkage data line ends 2 are fixedly installed on both the left and right ends of the top side inside the whole 1.

[0020] Reference Figure 3 The temperature-sensing magnetic power generation device 4 is electrically connected to the electric initiator linkage data line terminal 2. The electric initiator linkage data line terminal 2 is signal-linked with the nozzle terminal 3. When the temperature-sensing magnetic power generation device 4 senses the preset temperature threshold, it triggers the nozzle terminal 3 through the electric initiator linkage data line terminal 2 to complete the directional spraying of the fire extinguishing medium.

It is recommended that users install fire hydrants and water pipe connections within 30 meters of the battery swapping station. The station control system should monitor the batteries within the station 24 hours a day and have an early warning function. Upon triggering a thermal runaway early warning signal, the station control system should automatically hoist the faulty battery into the battery swapping channel.

[0022] Reference Figure 1 The exhaust ventilation system 9 can actively control the flow rate and direction of the air inside the whole 1, and the exhaust volume of the exhaust ventilation system 9 reaches no less than the actual air volume of the cabin per minute, ensuring that the internal gas is quickly replaced.

[0023] Reference Figure 1 The automatic fire extinguishing system 7 includes smoke detectors, heat detectors, fire detection probes, and an alarm system.

It can be sprayed onto people to aid escape. After its expiration date, it will naturally degrade and can be used as fertilizer without special treatment. It can immediately extinguish fires on battery 5. If the water-based fire extinguisher fails, the system will detect this and automatically trigger a continuous water supply to the interior of the main unit 1, completely immersing battery 5 inside for final fire extinguishing.

[0024] Reference Figure 1 The lighting system 10 includes lighting lamps and emergency lights, and the piping, wiring and the system itself are explosion-proof.

[0025] Reference Figures 1-3 The device 1 uses a metal roof directly as a lightning rod. At least two grounding electrodes are pre-embedded in the foundation of the casing of the device 1, and these grounding electrodes are reliably connected to the casing of the device 1. The grounding electrodes are pre-embedded simultaneously in the foundation of the battery swapping station, and the grounding resistance does not exceed 1 ohm, ensuring reliable grounding and lightning and explosion protection for the battery swapping station. The device has functions such as actively monitoring the operating status of the electric vehicle's BMS, the characteristic parameters of battery 5, and the operating status of the charger 8 itself. It adopts a safety redundancy design and can actively diagnose and handle equipment faults and operational anomalies, achieving active protection during the electric vehicle charging process. The device is equipped with a 4G communication module and uses a 4G communication data card to connect to the network, supporting login to the cloud platform via mobile APP, PAD, and PC terminals. This device enables remote monitoring, data query, and operation control of the charging status. It also features power outage recording, power outage fault identification, and operational data storage. The charging gun (unit 1) is equipped with an electronic locking device to prevent accidental disconnection during charging, ensuring the gun cannot be removed during charging. If the electronic lock fails to reliably engage, the power supply equipment or electric vehicle will automatically stop charging or not start charging. The charging gun also has an over-temperature power-off function, further enhancing charging safety. The charger cabinet (unit 8) and charging pile have an IP54 outdoor protection rating. The printed circuit boards, connectors, and other circuits inside the charger (unit 8) are treated for moisture resistance, mildew resistance, and salt spray resistance. The motor 8 casing and exposed iron bracket are equipped with double-layer anti-rust measures to achieve anti-rust (anti-oxidation) protection; the electric shock protection of the charger 8 meets the requirements of GB / T18487.1-2015 standard; each energized circuit of the charger 8 and the metal casing of each energized circuit to ground are subjected to a short-time impulse voltage test of the specified standard lightning wave according to their working voltage, and no breakdown discharge phenomenon occurs during the test; the charger 8 has overvoltage protection and undervoltage protection functions on the power input side; the charger 8 has output overvoltage protection function, and the charger 8 has output overcurrent and short circuit protection functions; the charger 8 has internal over-temperature protection function, and when the internal temperature reaches the protection value, it automatically reduces power or stops output. The charger 8 has protective measures; it also has an over-temperature power-off function. When the temperature is too high, it can automatically cut off the charging circuit to prevent accidents such as high-temperature spontaneous combustion and protect the charging equipment and the safety of the new energy vehicle. If the temperature rises by more than 15 degrees within 20 minutes during the charging process, the charger 8 will automatically trigger the temperature protection mechanism. The insulation detection function of the charger 8 works in conjunction with the vehicle insulation detection function. When the emergency stop switch or control guidance failure occurs during the charging process, the charger 8 can disconnect the DC output contactor within 100ms, and the DC output voltage drops to below 60V within 1 second. Before automatic charging, the charger 8 has a battery voltage detection function, and the charging process is started after the detection is qualified.

[0026] The implementation principle of a fire extinguishing device with non-pressurized temperature sensing for containers according to an embodiment of this application is as follows: The device is equipped with a charging interface and a charger 8 to provide a stable power supply for charging the battery 5 and operating the internal systems. The lighting system 10 provides explosion-proof lighting support for daily operation and maintenance and emergency response, ensuring the safety of basic operations. The explosion-proof control and autonomous alarm system 11 monitors internal smoke, combustible gas and temperature in real time. The gas sensing system detects gas concentration simultaneously. The charger 8 actively monitors the characteristic parameters of the electric vehicle BMS and battery 5 as well as its own operating status. The grounding and lightning protection structure ensures lightning and explosion protection. All monitoring data can be uploaded to the cloud platform through the 4G communication module to achieve remote real-time monitoring. The remote-controlled air conditioning cooling system 12 remotely and automatically adjusts the internal temperature according to the battery condition to avoid thermal runaway caused by high temperature; the exhaust ventilation system 9 achieves rapid internal gas replacement with a minute exhaust volume of not less than the cabin volume, exhausting hot air and harmful gases to maintain a suitable working environment. When the temperature-sensing magnetic power generation device 4 senses the preset temperature, or when the temperature sensor or smoke sensor detects a fire precursor or the gas concentration exceeds the standard, the system will immediately disconnect the circuit switch, and the explosion-proof control and autonomous alarm system 11 will trigger an audible and visual alarm. If the temperature reaches 170℃ or an open flame or charging short circuit occurs, the aerosol fire extinguishing device will automatically start. At the same time, the temperature-sensing magnetic power generation device 4 will trigger the nozzle end 3 through the data line terminal 2 of the electric initiator, so as to achieve the spraying of the fire extinguishing medium without dead angles and complete the initial fire handling. If the water-based fire extinguisher fails in the initial stage, the automatic fire extinguishing system 7 will trigger a continuous water injection to completely submerge the battery 5 and achieve final fire extinguishing. The faulty battery can be automatically hoisted to the battery swapping channel to prevent the fire from spreading. The charger 8 has multiple protections including input and output overvoltage, overcurrent, short circuit, and internal overtemperature. The charging gun is electronically locked to prevent accidental disconnection. Over-temperature power-off and protection against temperature rise exceeding 15 degrees Celsius in 20 minutes further enhance charging safety. In the event of an emergency stop or control guidance failure, the charger 8 disconnects the DC contactor within 100ms and reduces the output voltage to below 60V within 1 second. In addition, battery voltage detection and insulation detection must be completed before charging to coordinate with the vehicle, thus avoiding safety risks throughout the entire charging process. The device has the functions of power failure recording, fault identification and data storage. All faults and early warning signals can be pushed through the cloud platform to realize rapid fault tracing and handling. At the same time, it supports remote querying and control of the charging process, improving operation and maintenance efficiency.
