Description

Technical Field

[0001] This application relates to the field of fire safety, and in particular to a safety assessment system for use after gas fire suppression in a wine cellar. Background Technology

[0002] With rapid industrialization, the storage and management of various flammable and explosive materials has become a significant challenge in the field of fire safety. Wine cellars, in particular, pose a high risk of fire due to the large quantities of flammable alcoholic beverages they store. Furthermore, once a fire breaks out, it can easily spread, further expanding the fire's reach and increasing the difficulty of extinguishing it. Therefore, gas extinguishing systems, with their advantages of speed, efficiency, and no secondary pollution, have become an important and commonly used technical means for fire protection in wine cellars.

[0003] Gaseous fire suppression systems are particularly suitable for enclosed spaces such as warehouses and computer rooms. Carbon dioxide, as a gaseous fire extinguishing agent, is widely used in industrial and commercial settings due to its significant fire extinguishing effect, minimal residue, and non-destructive properties. However, after a carbon dioxide fire is extinguished, the high concentration of carbon dioxide in the storage room can easily cause asphyxiation and other safety issues. Therefore, post-fire environmental safety assessment and gas disposal have become key issues in fire protection system design.

[0004] Traditional gas extinguishing systems often lack the means to assess the safety of the site after extinguishing a fire, especially after using high concentrations of carbon dioxide to extinguish a fire, making it difficult to accurately determine whether the site is suitable for personnel to enter. Utility Model Content

[0005] Based on this, a safety assessment system for gas fire suppression in wine cellars is provided, which improves safety after fire suppression, realizes intelligent environmental monitoring and control, prevents reignition, ensures safe disposal after fire suppression, reduces the risk of secondary injury to personnel, and improves emergency response efficiency.

[0006] Therefore, in a first aspect, embodiments of this application provide a safety assessment system for post-fire suppression of a wine cellar gas, installed in the wine cellar. The safety assessment system for post-fire suppression of a wine cellar gas includes: an oxygen sensor, a first carbon dioxide sensor, a first temperature sensor, a smoke sensor, a heat detector, a flame recognition camera, and an exhaust system located in the wine cellar. It also includes a control center located outside the wine cellar, and the control center is electrically connected to the oxygen sensor, the first carbon dioxide sensor, the first temperature sensor, the smoke sensor, the heat detector, the flame recognition camera, and the exhaust system.

[0007] In one embodiment, the control center includes a fire control cabinet, a status monitor, and a terminal computer that are electrically connected to each other.

[0025] Traditional gas extinguishing systems often lack the means to assess the safety of the site after extinguishing a fire, especially after using high concentrations of carbon dioxide to extinguish a fire, making it difficult to accurately determine whether the site is suitable for personnel to enter.

[0026] To solve the above problems, refer to Figure 1 and Figure 2 , Figure 1 The diagram shows a structural schematic of a safety assessment system for use after extinguishing a gas fire in a wine cellar. Figure 2 A flowchart is shown for a safety assessment system used after a gas fire in a wine cellar.

[0027] This application provides a safety assessment system for post-fire suppression of a gas fire in a wine cellar. The system is installed in the wine cellar 1 and includes: an oxygen sensor 2, a first carbon dioxide sensor 3, a first temperature sensor 4, a smoke sensor 5, a heat detector 6, a flame recognition camera 7, and an exhaust fan 8, all located in the wine cellar 1. It also includes a control center 9 located outside the wine cellar, which is electrically connected to the oxygen sensor 2, the first carbon dioxide sensor 3, the first temperature sensor 4, the smoke sensor 5, the heat detector 6, the flame recognition camera 7, and the exhaust fan 8.

[0028] It is important to understand that oxygen sensor 2 is located in wine cellar 1. Oxygen sensor 2 is used to detect the oxygen concentration in wine cellar 1 to determine whether it is suitable for personnel to enter. Low-oxygen environments may pose a threat to personnel health; therefore, real-time monitoring of oxygen concentration is an important measure to ensure safety.

[0029] The first carbon dioxide sensor 3 is located in wine cellar 1 and is used to detect the carbon dioxide concentration within wine cellar 1. Carbon dioxide is a common fire extinguishing gas, but excessively high concentrations can pose a suffocation hazard. Monitoring carbon dioxide concentration allows for effective assessment of air quality and safety.

[0030] The first temperature sensor 4 is located in wine cellar 1 and is used to detect the temperature inside wine cellar 1. After a fire, the temperature may rise abnormally, endangering personnel safety. The monitoring by the first temperature sensor 4 can provide necessary temperature information to ensure the safety of personnel entering the cellar.

[0031] The heat detector 6, located in the wine cellar 1, is used to detect temperature changes within the wine cellar. It typically possesses high sensitivity and stability, enabling a rapid response in the early stages of a fire. It detects fires by monitoring changes in ambient temperature. When the ambient temperature exceeds a set value, the heat detector 6 will issue an alarm signal. The heat detector 6 works in conjunction with the first temperature sensor 4 to improve accuracy: the first temperature sensor 4 provides more precise temperature readings, helping to distinguish between actual temperature changes and those caused by non-fire factors such as dust. This helps reduce false alarms and improve the accuracy of fire alarms; it also enhances reliability: by combining the heat detector 6 and the first temperature sensor 4, multiple detection methods can be implemented within a single system, thereby improving the overall reliability of the system. Even if one component fails, the other component can still function normally, ensuring the stable operation of the fire alarm system.

[0032] Smoke sensor 5 is located in wine cellar 1 and is used to detect the smoke concentration within wine cellar 1. After a fire, the smoke level rises abnormally, endangering personnel safety. The monitoring by smoke sensor 5 can provide necessary smoke information to ensure the safety of personnel entering the cellar.

[0033] The flame detection camera 7 is located in the wine cellar 1. It captures images of the wine cellar 1, generating flame images, which are then used to detect whether there is an open flame inside the wine cellar 1. By monitoring the fire situation in real time through the flame detection camera 7, residual fire sources can be detected in a timely manner, preventing the risk of reignition.

[0034] The exhaust unit 8 is located in the wine cellar 1. The exhaust unit 8 can replace the air in the wine cellar 1 and regulate the gas composition and temperature inside the wine cellar 1. After a fire occurs, the exhaust unit 8 can quickly remove smoke and harmful gases, while reducing the temperature inside the wine cellar 1, providing a safe working environment for subsequent personnel rescue and cleanup.

[0035] It also includes a control center 9 located outside the wine cellar 1 to prevent damage to the control center 9 inside the wine cellar 1. The control center 9 is electrically connected to oxygen sensor 2, first carbon dioxide sensor 3, first temperature sensor 4, smoke sensor 5, heat detector 6, flame recognition camera 7, and exhaust system 8 to collect and process various monitoring data. The control center 9 can control the operation of the exhaust system 8 based on oxygen concentration, carbon dioxide concentration, temperature, and camera image information, determine the minimum safe evacuation distance outside the wine cellar 1, and ensure that the environmental conditions inside the wine cellar 1 are suitable for personnel entry. This enables rapid response and environmental control after a fire in the wine cellar 1, ensures the safety of the scene after the fire is extinguished, realizes intelligent environmental monitoring and control, prevents reignition, reduces the risk of secondary injury to personnel, and improves emergency response efficiency.

[0036] In some alternative embodiments, the control center 9 includes a fire control cabinet 91, a status monitor 92, and a terminal computer 93 that are electrically connected to each other. The fire control cabinet 91 is capable of monitoring and controlling the operating status of fire-fighting equipment.

[0037] The fire control cabinet 91 can monitor the status of fire pumps, sprinkler systems, fire extinguishers, and other equipment in the wine cellar 1 in real time, promptly detect and handle malfunctions, and ensure the normal operation of the equipment. In addition, the fire control cabinet 91 can also provide alarm signals; when fire-fighting equipment malfunctions or a fire is detected, it will promptly issue an alarm signal to alert personnel to take action. In the initial stage of a fire, the fire control cabinet 91 can automatically activate the fire extinguishing devices, effectively curbing the spread of fire and reducing losses.

[0038] Status monitor 92 is used to acquire operational information of the gas fire suppression system within wine cellar 1. This information helps determine whether the fire suppression system is functioning properly and to assess its effectiveness.

[0039] The terminal computer 93 is electrically connected to the oxygen sensor 2, the first carbon dioxide sensor 3, the first temperature sensor 4, the smoke sensor 5, the heat detector 6, the flame recognition camera 7, the exhaust fan 8, the fire control cabinet 91, and the status monitor 92. It is used to calculate and process the signals from the oxygen sensor 2, the first carbon dioxide sensor 3, the first temperature sensor 4, the smoke sensor 5, the heat detector 6, the flame recognition camera 7, the exhaust fan 8, the fire control cabinet 91, and the status monitor 92, to enable rapid response and environmental control after a fire in the wine cellar 1, and to ensure the safety of the scene after the fire is extinguished.

[0040] In some optional embodiments, a gaseous fire suppression system 10 is also included. The control center 9 is electrically connected to the gaseous fire suppression system 10, and the gas used in the gaseous fire suppression system 10 is carbon dioxide. When the control center 9 calculates, based on the detection signals fed back from various devices, that fire suppression is still needed in the wine cellar 1, the control center 9 controls the gaseous fire suppression system 10 to spray carbon dioxide into the wine cellar 1 for secondary fire suppression, thereby ensuring the safety of the wine cellar 1, avoiding secondary injuries to staff and rescue personnel, and improving the efficiency and safety of emergency response.

[0041] In some optional embodiments, the gas extinguishing assembly 10 includes a gas cylinder room 101 and multiple nozzles 102 located outside the wine cellar 1 and located inside the wine cellar 1. The multiple nozzles 102 are spaced apart, and the gas cylinder room 101 is connected to the nozzles 102 via pipes. The gas cylinder room 101 is located outside the wine cellar 1 to prevent damage. The spaced arrangement of the multiple nozzles 102 improves the spraying effect within the wine cellar 1, thereby enhancing the extinguishing effect of this application on the wine cellar 1.

[0042] In some optional embodiments, the exhaust component 8 can be either an air conditioner or a fan, and this application does not impose any limitations. The exhaust component 8 can be an air conditioner, which can regulate the temperature in the wine cellar 1 while exchanging air. The exhaust component 8 can also be an emergency exhaust fan, which can perform ventilation treatment on the wine cellar 1.

[0043] In some optional embodiments, the flame recognition camera 7 is a high-definition dome camera. High-definition dome cameras offer high-definition image quality: they are typically equipped with high-definition lenses and large sensors, providing high-resolution video streams with clearer and more detailed images, suitable for scenarios requiring high-definition monitoring. High-definition dome cameras have an aesthetically pleasing appearance: their design makes the device more concealed and aesthetically pleasing, not disrupting the overall interior decoration style, making them suitable for installation in locations requiring both aesthetic appeal and concealed monitoring. High-definition dome cameras are easy to deploy and manage: due to their compact size and high integration, they can be easily placed in the location requiring monitoring and remotely managed and controlled through the control center 9. High-definition dome cameras have strong environmental adaptability: they are typically waterproof and dustproof, capable of operating normally in harsh environments and adapting to different usage scenarios. Intelligent and user-friendly design: they support remote control, intelligent alarms, night vision functions, etc., providing all-weather monitoring services with convenient operation and a good user experience. High-definition dome cameras are multifunctional: they typically have multiple functions, such as automatic cruise, pan-tilt rotation, and day / night operation, adapting to different monitoring needs.

[0044] Furthermore, a sliding rail can be installed on the roof of the wine cellar 1, and the flame recognition camera 7 can be slidably connected to the sliding rail, thereby increasing the shooting range of the flame recognition camera 7 and thus improving the monitoring effect of the wine cellar 1.

[0045] In some optional embodiments, a second carbon dioxide sensor 11 is also included. The second carbon dioxide sensor 11 is located outside the wine cellar 1 and is electrically connected to the control center 9. Located outside the wine cellar 1, the second carbon dioxide sensor 11 can detect the carbon dioxide content outside the wine cellar 1. Electrically connected to the control center 9, it can transmit the carbon dioxide information from outside the wine cellar 1 to the control center 9. At this time, the control center 9 can simultaneously receive signals from the first carbon dioxide sensor 3 regarding the carbon dioxide inside the wine cellar 1 and from the second carbon dioxide sensor 11 regarding the carbon dioxide outside the wine cellar 1. This allows for accurate detection of gas changes inside and outside the wine cellar 1, ensuring that after gas extinguishing, the environment can be assessed promptly and accurately to determine if it is suitable for personnel to enter, thus avoiding secondary injuries caused by the failure to promptly remove harmful gases in traditional systems.

[0046] In some optional embodiments, at least two second carbon dioxide sensors 11 are provided and spaced apart from each other. The number of second carbon dioxide sensors 11 can be two, three, or other numbers, and this application does not impose any restrictions. The control center 9 can take the average data of multiple second carbon dioxide sensors 11 as the detection result of carbon dioxide concentration outside the wine cellar 1, thereby improving the detection effect of carbon dioxide outside the wine cellar 1 and improving the judgment accuracy of the control center 9.

[0047] In some optional embodiments, a second temperature sensor 12 is also included. The second temperature sensor 12 is located outside the wine cellar 1 and is electrically connected to the control center 9. Located outside the wine cellar 1, the second temperature sensor 12 can detect the temperature outside the wine cellar 1. Electrically connected to the control center 9, it can transmit the temperature outside the wine cellar 1 to the control center 9. At this time, the control center 9 can simultaneously receive the temperature signal from the first temperature sensor 4 (indicating the temperature inside the wine cellar 1) and the temperature signal from the second temperature sensor 12 (indicating the temperature outside the wine cellar 1), thereby accurately judging the temperature situation of the wine cellar 1. This further improves safety and intelligence, and significantly reduces the potential secondary injuries to personnel after fire extinguishing.

[0048] In some optional embodiments, at least two second temperature sensors 12 are provided and spaced apart from each other. The number of second temperature sensors 12 can be two, three, or other numbers, and this application does not impose any restrictions. The control center 9 can take the average data of multiple second temperature sensors 12 as the detection result of the external temperature of the wine cellar 1, thereby improving the detection effect of the external temperature of the wine cellar 1 and improving the judgment accuracy of the control center 9.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
