Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and in particular to an intelligent non-pressurized perfluorohexanone fire extinguisher. Background Technology

[0002] Fire extinguishers are common firefighting equipment. Based on the type of extinguishing agent, they can be categorized into dry powder extinguishers, carbon dioxide extinguishers, foam extinguishers, water-based extinguishers, ammonium chloride extinguishers, halon extinguishers, and metal extinguishers. Different types of extinguishing agents are suitable for slightly different firefighting scenarios. For example, carbon dioxide extinguishers are suitable for electrical equipment fires, foam extinguishers are suitable for grease fires, while halon extinguishers can be used for both electrical equipment fires and flammable liquid fires, making them a commercially promising type of fire extinguisher.

[0003] Traditional fire extinguishers are mostly handheld and require manual control. In some scenarios, traditional fire extinguishers have been integrated with automation technology to form intelligent fire suppression systems with automatic detection and extinguishing functions, which are now widely used in homes, businesses, and parking sheds in residential areas. While these intelligent fire suppression systems achieve intelligent detection and extinguishing to a certain extent, they suffer from the following problems due to structural limitations: First, the coordination between fire extinguishers and intelligent control systems is not reliable enough; detection, analysis, extinguishing, and monitoring are affected by the fire situation, resulting in insufficient reliability. Second, the extinguishing agents in fire extinguishers are mostly stored under pressure, maintaining a high-pressure state for extended periods, which can easily lead to leakage, pressure loss, and even failure, resulting in high maintenance and repair costs. Third, fire extinguishers and control systems are too bulky to be miniaturized, making them unsuitable for effective installation and normal operation in smaller spaces such as electrical distribution boxes. Fourth, due to the use of traditional extinguishing agents and control methods, the extinguishing efficiency is insufficient, the methods are limited, and it is impossible to provide timely feedback to users on the fire situation and the operating status of the fire suppression system.

[0004] The aforementioned problems did not attract much attention when there was sufficient personnel, small fire protection areas, and low fire protection requirements. However, as residential and office buildings are built taller and the number of electrical devices increases, the space for fire protection installations becomes increasingly limited. The exponential growth in personnel numbers, electrical equipment density, and monitoring areas places enormous pressure on fire protection systems. Even if smoke detectors, gas detectors, and surveillance cameras are installed haphazardly in various areas, it is still impossible to reliably realize the functions of detection, analysis, fire extinguishing, monitoring, and analysis. Once a fire occurs, problems such as fire extinguishers failing to activate, fire extinguishers failing to extinguish effectively, fire extinguishers malfunctioning, fire extinguishing effects being unassessable, and the post-fire scene being undetectable frequently occur. On the one hand, this poses a great risk to personal and property safety; on the other hand, firefighters cannot effectively monitor and assess the fire scene and fire protection systems, making it difficult to achieve effectiveness, timeliness, and economy in subsequent fire-fighting measures.

Figure 6 This is a cross-sectional view of the intelligent non-pressurized perfluorohexanone fire extinguisher in an embodiment of this utility model. Figure 7 This is a partial enlarged view of the intelligent non-pressurized perfluorohexanone fire extinguisher in this embodiment of the present invention.

[0033] like Figures 1 to 7 As shown, the intelligent non-pressurized perfluorohexanone fire extinguisher provided by this utility model includes: a fire extinguishing module, a monitoring module, and a control module.

[0034] The fire extinguishing module is used to spray extinguishing agent at the fire source to extinguish the fire.

[0035] The fire extinguishing module in this embodiment includes: a tank 2, liquid perfluorohexanone 12, a pressure assembly, and a nozzle 3. The tank 2 can be cylindrical, cubic, or other shapes, and has an internal cavity for storing the extinguishing agent. The tank 2 includes an inlet and an outlet, and the nozzle 3 is installed at the outlet of the tank 2 (see...). Figure 1 and Figure 6 The nozzle 3 has a jet hole inside (see...). Figure 6 (Unmarked), used to spray the extinguishing agent from the jet orifice. When the tank body 2 is cylindrical, the inlet and outlet are generally located at both ends of the cylinder.

[0036] Perfluorohexanone 12, used as an extinguishing agent, is liquid at room temperature and located within the canister. The canister 2 has a seal at its opening to prevent perfluorohexanone 12 from leaking from the nozzle. This seal ruptures or detaches when the pressure inside the canister 2 increases to a certain level, allowing gas, liquid, or a gas-liquid mixture to be ejected from the jet orifice. One possible seal is a circular cardboard with a sealing function, glued to the circular jet orifice. Under normal pressure, the sealing effect of the cardboard prevents perfluorohexanone from leaking from the nozzle. When the pressure inside the canister exceeds a certain value, the pressure difference between the inside and outside of the canister forces the cardboard open, allowing the extinguishing agent inside the canister 2 to be ejected from the jet orifice.

[0037] The pressure assembly includes a solid nitrogen sealing assembly 14, an exciter 13, and an excitation connector 4. The function of the pressure assembly is to cause a sudden increase in pressure (typically 2 MPa or higher) when solid nitrogen 15 sublimates into a gaseous state within the solid nitrogen sealing assembly 14 and enters the tank 2. The excitation connector 4 is installed at the inlet of the tank 2. Its function is to transmit an excitation signal to the exciter 13, enabling the exciter 13 to break the protective shell of the solid nitrogen sealing assembly 14, thereby rapidly vaporizing the solid nitrogen 15. A possible structure and positional relationship of the solid nitrogen sealing assembly 14, the exciter 13, and the excitation connector 4 are as follows: Figure 6 As shown. One possible structure of the solid nitrogen sealing assembly 14 is as follows: the solid nitrogen 15 can be cylindrical or spherical, sealed in an empty shell to form the so-called solid nitrogen sealing assembly 14 in this embodiment of the present invention. The structure of the empty shell can be destroyed by the exciter 13. It should be noted that the function of the exciter 13 is only to destroy the outer shell of the solid nitrogen sealing assembly 14 (i.e., the aforementioned empty shell, which can be ruptured or punctured under mechanical action, causing the solid nitrogen to vaporize), so as to release gaseous nitrogen gas. There are many types of exciters 13 and corresponding shells, and many mature products are available on the market. They can be selected according to the destruction mechanism and design requirements. The solid nitrogen sealing assembly 14 is disposed on the exciter 13, located at... Figure 6 Inside the tank 2 shown, the exciter 13 is electrically connected to the excitation connector 4. The excitation connector 4 is used to receive an excitation signal from the outside and switch the operating state of the exciter 13 to vaporize the solid nitrogen sealing assembly 14 and achieve a rapid increase in pressure inside the tank 2. To enable rapid vaporization of the solid nitrogen 15, the structure of the exciter 13 can be referenced. Figure 7 As shown, the destruction mechanism 16 inside the activator 13 is used to destroy the sealed shell of the solid nitrogen 15. A snap-fit ​​positioning with a through hole is provided at the connection between the activator 13 and the solid nitrogen sealing assembly 14. The function of the through hole is to quickly discharge the nitrogen gas released from the destruction point into the tank. The pressure inside the tank increases rapidly, and the airflow carries liquid perfluorohexanone and sprays it out from the nozzle. The atomized perfluorohexanone is sprayed towards the fire source, which on the one hand cools the fire source, and on the other hand isolates oxygen, thus achieving a dual fire extinguishing function.

[0038] The monitoring module, used to monitor fire sources within the monitoring space to detect fires, is existing technology. A common monitoring module includes a camera, a signal transmission line, and a signal processing module. The camera captures images of a specific area and transmits them to the program execution module via the signal transmission line. The signal processing module (including common modules such as processors, memory, and input / output, which are existing technologies) runs a computer program that determines whether a fire has occurred based on the transmitted images. If a fire is detected, a fire information signal is sent after the judgment. This fire information signal is then sent to the control module, which sends an activation signal to the activation connector 4. In this embodiment, the monitoring module and the activation connector 4 are electrically connected to the control module. The control module acts like a computer host, making logical judgments, using the information obtained from the monitoring module to determine whether to send an activation signal to the activation connector 4, thereby switching the working state of the exciter 13 to achieve effective fire extinguishing. All of this is existing technology.

[0039] The working principle of the intelligent non-pressurized perfluorohexanone fire extinguisher provided by this utility model is as follows: When the monitoring module detects a fire source in the monitoring space, the control module sends an excitation signal to the excitation connector 4. The excitation signal is transmitted to the exciter 13 through the excitation connector 4. The exciter 13 releases solid nitrogen 15 through the destruction mechanism 16, which causes a sudden increase in pressure inside the tank 2. Liquid perfluorohexanone 12 is then sprayed out from the nozzle 3 in an atomized state. After being sprayed onto the fire source, the liquid perfluorohexanone 12 will quickly vaporize and absorb heat, reducing the temperature of the combustible. At the same time, the vaporized perfluorohexanone adheres to the vicinity of the fire source, isolating oxygen from the combustible and eliminating the conditions for continued combustion, thereby extinguishing the fire.

[0040] This technical solution provides a miniaturized and intelligent fire extinguisher using perfluorohexanone as the extinguishing agent. The extinguisher utilizes the heat absorption during vaporization and the oxygen-isolating properties of perfluorohexanone to extinguish fires without causing secondary damage to electrical equipment. In particular, by integrating the monitoring and control modules into the extinguisher, it prevents fires from failing due to damage to the control circuitry, thus improving the reliability and effectiveness of fire suppression. Furthermore, compared to existing fire extinguishers, it has a compact structure and high space utilization, making it suitable for confined spaces such as electrical cabinets.

[0041] Optionally, the monitoring module includes at least two of an optical detection unit, a smoke detection unit, or a temperature detection unit, and the optical detection unit, the smoke detection unit, or the temperature detection unit are electrically connected to the control module.

[0042] The optical detection unit is used to detect fire sources in the monitoring space and is a prior art technology.

[0043] The smoke detection unit is used to detect the air in the monitored space and to determine whether a fire has occurred by detecting smoke particles in the air. This is existing technology.

[0044] The temperature detection unit is used to detect the temperature in the monitored space. Common detection methods, such as infrared detection, are used to determine whether a fire has occurred, which is existing technology.

[0045] In this technical solution, two or more of the above-mentioned detection units (each detection unit is independent of each other, i.e., they are connected in parallel) are integrated into the fire extinguisher (all connected to the control module). On the one hand, the accuracy of fire detection can be improved by the joint judgment of the two detection units. On the other hand, it is also to use the more sensitive detection unit to start the control module, and then use the control module to start another detection unit for active detection, thereby improving the reliability and timeliness of fire detection. In other words, the detection process has been improved.

[0046] Optionally, it further includes: a first excitation wire, which is connected to an excitation connector, the first excitation wire being an excitation cable for providing an excitation signal to the excitation connector.

[0047] This technical solution involves directly supplying an excitation signal to the excitation connector via an excitation cable to initiate the fire extinguishing process.

[0048] Optionally, it also includes: a second excitation wire, which is connected to the excitation connector. The second excitation wire is an excitation fuse used to provide an excitation signal to the excitation connector.

[0049] This technical solution uses a trigger rope to provide the ignition signal, and is mainly used in situations where there is an open flame or the fire can reach the trigger rope.

[0050] It should be noted that, in Figure 7 Only one firing wire 18 is shown in the diagram. In reality, multiple firing wires of different types can be arranged in a fire extinguisher, depending on the fire protection requirements.

[0051] Optionally, it also includes a wireless communication module, which is electrically connected to the control module.

[0052] One possible wireless communication module uses LoRa wireless communication technology.

[0053] This technical solution was adopted to prevent fires from damaging communication lines and affecting fire monitoring.

[0054] Optionally, it further includes a positioning module, which is electrically connected to the control module.

[0055] This technical solution allows users to easily locate fire extinguishers in a timely manner, facilitating management and maintenance.

[0056] Optionally, it also includes an alarm module 8, which is electrically connected to the control module.

[0057] This technical solution is adopted to promptly warn users when a fire is detected.

[0058] Optionally, the alarm module 8 uses an audible and visual device for warning.

[0059] This technical solution was adopted because the combined sound and light alarm device provides excellent warning effects day and night. Figure 5 As shown, the sound can be emitted from the gap at the bottom of the fire extinguisher, and a warning light can be installed at the bottom of the fire extinguisher. One possible warning light is a red-yellow-green warning light, with red indicating that a fire has been discovered, yellow indicating that a fire exists but needs to be verified, and green indicating that there is no fire.

[0060] Optionally, it also includes: a housing 1, wherein the fire extinguishing module, the monitoring module and the control module are located inside the housing.

[0061] like Figure 1 and Figure 5 As shown, the purpose of setting up the box is to protect the various components of the fire extinguisher in this embodiment, and at the same time to facilitate the installation and arrangement of the fire extinguisher.

[0062] One possible structural layout of box 1 is as follows Figure 5 and Figure 6 As shown, a control end cover 9 and a fire extinguishing end cover 10 are respectively provided at both ends of the housing 1. In order to supply power or control the intelligent non-pressurized perfluorohexanone fire extinguisher, a power interface 14 and a network cable interface 12 are provided at the control end cover 9. The power interface 14 is electrically connected to the control module and is used to supply power to the control module, and the network cable interface 12 is electrically connected to the control module and is used to communicate with the control module.

[0063] To achieve miniaturization of the fire extinguisher, an electronic component mounting area (i.e., Figure 6 The area between the right end of the middle tank 2 and the control end cover 9, such as Figure 6 As shown, the wireless communication module (not shown in the figure, which is electrically connected to the control module to achieve wireless communication), the positioning module (not shown in the figure, which is electrically connected to the control module to locate the fire extinguisher) and the control module can be installed together in the electronic component installation area to reduce the space occupied.

[0064] Optionally, it further includes: an adjustment module, wherein the housing 1 is located on the adjustment module, and the adjustment module is used to adjust the orientation of the nozzle.

[0065] One possible adjustment module is a rotatable mechanism fixed to the wall, including a rotating motor and a rotating flange.

The control module controls the rotation direction, rotation amplitude, and rotation frequency of the rotating motor according to the information obtained by the monitoring module, so that the fire extinguisher nozzle in this embodiment is always facing the area where the fire occurs, thereby achieving dynamic fire extinguishing.
