[0046] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0047] One embodiment of the present invention relates to an explosion-proof fire extinguishing cabinet 100. For example... Figure 1 , Figure 2 As shown, the explosion-proof fire extinguishing cabinet 100 includes: a cabinet body 1, a moving component 2, a flame-retardant socket module 3, a fire extinguishing module 4, a surge module 5, an air switch module 6, and a pressure relief module 7. The cabinet body 1 has a cabinet main body 11 and a protrusion 12 connected to the cabinet main body 11. The protrusion 12 protrudes outside the cabinet main body 11, and its internal space is connected to the internal space of the cabinet main body 11. The moving component 2 is connected to the cabinet main body 11. The flame-retardant socket module 3, fire extinguishing module 4, surge module 5, and air switch module 6 are disposed within the protrusion 12. The pressure relief module 7 is disposed within the cabinet main body 11. The air switch module 6 is electrically connected to the surge module 5. The flame-retardant socket module 3 is connected to a plug for external power supply; devices requiring charging, such as emergency lights, can be charged by inserting the flame-retardant socket module 3 after being placed inside the cabinet main body 11. The explosion-proof fire extinguishing cabinet 100 also includes a cabinet door 401 for opening or closing the cabinet.

[0048] The rail transit system has a large number of emergency lighting fixtures at each station for emergency lighting and routine maintenance. These emergency lighting fixtures require daily charging of their built-in lithium batteries. Currently, the charging stations are located in the station control center. The owner is concerned that the lithium batteries in the fixtures might explode and ignite during installation or charging, potentially triggering a chain reaction in the station's fire suppression system. To address this issue, the rail transit operating company requested that we develop a portable explosion-proof fire extinguisher (model 100) made of perfluorohexanone (PFH). This fire extinguisher should be power-off resistant, flame-retardant, explosion-proof, and capable of diluting dense smoke. In the event of a battery explosion during charging, it should be able to quickly cut off the power, seal and transfer the burning battery, control the fire, and prevent its spread. During the transfer, the internal pressure should be adjusted to prevent the cabinet from bursting. Simultaneously, the design of the explosion-proof fire extinguisher (model 100) must dilute the dense smoke generated during the fire to prevent panic among station personnel.

[0049] As described above, the protrusion 12 extending beyond the cabinet body 11 allows modules such as the flame-retardant socket module 3, fire extinguishing module 4, surge module 5, and air switch module 6 to be housed within the protrusion 12, without occupying space within the cabinet body 11. This frees up space within the cabinet body 11, enabling the placement of emergency lights or equipment requiring explosion-proof protection. In contrast, existing cabinets are large rectangular units, requiring space for all components and modules while still needing room for emergency lights or explosion-proof equipment, resulting in a large overall size. This solution allows for more modules to be placed within the protrusion 12, reducing the cabinet size to accommodate only emergency lights or explosion-proof equipment. Furthermore, the inclusion of a movable component 2, combined with the miniaturized cabinet, facilitates the movement of the explosion-proof fire extinguishing cabinet 100. The flame-retardant socket module 3 allows charging devices to be placed within the cabinet body 11 for charging. This invention addresses the problem of the existing explosion-proof fire extinguisher cabinet 100 being too large and difficult to move flexibly. When a fire breaks out inside the explosion-proof fire extinguisher cabinet 100, it can be quickly moved to a safe area.

[0050] Specifically, the flame-retardant socket module 3 adopts a 16A rated current specification, and a single socket can carry the power of devices up to 3500W, fully meeting the power requirements of conventional charging equipment. In this embodiment, the explosion-proof fire extinguishing cabinet 100 is equipped with two independent socket units, supporting parallel charging of multiple devices, balancing ease of use and load balance, and avoiding electrical risks caused by overloading of a single socket. The core of the flame-retardant socket module 3 uses flame-retardant engineering plastic as the shell material, with a limiting oxygen index (LOI) ≥32%, far exceeding the 21% of ordinary plastics. When encountering abnormal currents such as short circuits or overloads, the shell can form a dense carbonized layer at high temperatures, blocking the path of flame spread and preventing the socket itself from becoming a fire source. At the same time, it is equipped with an overcurrent protection device, which automatically cuts off the power supply within 0.1 seconds when the current exceeds the 16A threshold, fundamentally avoiding the fire hazard caused by short circuits and providing double safety protection for equipment charging scenarios. The pressure relief module 7 can be installed at the bottom of the cabinet body 11. It employs a composite filter structure of activated carbon and HEPA. The activated carbon adsorbs harmful gases produced by combustion (such as carbon monoxide and hydrogen sulfide), while the HEPA filter intercepts PM2.5 and larger harmful particulate matter, achieving a filtration efficiency of 99.97%. When combustion occurs inside the explosion-proof fire extinguishing cabinet 100, the pressure relief module 7 effectively prevents the leakage of harmful substances, avoiding secondary harm to the surrounding environment and personnel health, meeting both environmental and safety standards. The pressure relief module 7 has a built-in pressure-sensing diaphragm. When pressure fluctuations (exceeding 0.01 MPa) occur inside the cabinet due to combustion or equipment operation, the diaphragm automatically opens to release pressure, ensuring that the pressure inside the cabinet remains balanced with the external environment. This design avoids the risk of deformation and rupture caused by excessive pressure in traditional sealed cabinets, ensuring the structural integrity of the equipment while maintaining the normal operating environment of the internal equipment. Figure 1As shown, the movable component 2 includes: anti-slip casters 21 located at the bottom of the cabinet body 11, and triangular casters 22 located on the back of the cabinet body 11. The anti-slip casters 21 can be rubber wheels, with four casters located at the four corners of the bottom of the cabinet. The triangular casters 22 are located on the lower back of the cabinet body 11 and can be used on stairs or other surfaces. A handle 301 is also provided on the top of the cabinet body 11. The handle 301 is detachable for easy use and storage in different scenarios. The detachable structure uses quick-release buckles or threaded connections, facilitating the installation and removal of the handle 301 without affecting the cabinet's appearance or use. The handle 301 features an ergonomic design with a curved gripping section and an anti-slip textured surface for improved grip comfort. This enhances mobility and stability. Anti-slip wheels 21, combined with precision bearings, ensure smooth and uninterrupted rotation during cabinet movement. The anti-slip design prevents slippage, improving stability. The anti-slip wheel assembly and compatible handle 301 work together to reduce the risk of equipment tipping or damage due to slippage or uncomfortable grip during movement. The fire suppression module 4, equipped with a temperature sensing module, automatically triggers the fire suppression device 201 when a temperature surge of 140℃±5℃ is detected, releasing environmentally friendly perfluorohexanone (PFH). The fire suppression gas fills the internal space of the equipment within 3 seconds, extinguishing initial fires through a combination of chemical inhibition and physical cooling, enabling rapid handling of fire hazards and preventing the fire from spreading. The surge module 5 incorporates multi-stage varistors and gas discharge tubes, enabling rapid response to instantaneous voltage fluctuations in the power grid (such as surges caused by lightning strikes or equipment start-up / shutdown). When the voltage exceeds the rated value (220V±10%), the surge module 5 guides the surge energy to the ground wire within nanoseconds, ensuring that the output voltage is stable within a safe range and avoiding damage such as chip burnout and data loss caused by voltage fluctuations to the charging equipment, effectively protecting the core components of the equipment.

[0051] Furthermore, such as Figure 5 , Figure 7 As shown, an opening slot 110 is provided on the back of the cabinet body 11, and a protrusion 12 is provided on the outside of the back of the cabinet body 11 and is connected to the opening slot 110. In this embodiment, as... Figure 7 , Figure 8 , Figure 9 As shown, in order to achieve a detachable connection between the protrusion 12 and the cabinet body 11, a sliding groove 111 extending along the length direction of the opening slot 110 is provided on the back of the cabinet body 11. The protrusion 12 is slidably connected to the sliding groove 111 and covers the opening slot 110. Figure 2 As shown, a mounting rail 13 is provided on the wall surface of the protrusion 12, and the fire extinguishing module 4 and surge module 5 are mounted on the mounting rail 13. Figure 5 , Figure 6 , Figure 9As shown, the protrusion 12 can also be connected to the cabinet body 11 via a snap-fit ​​structure, or locked to the cabinet body 11 with screws, or the cabinet body 11 and the protrusion 12 can be a single piece. Both the upper and lower ends of the protrusion 12 are provided with extension edges 121, which can be inserted into the slide groove 111 to mate with the cabinet body 11. A sealing strip 122 is fitted onto the extension edge 121 to seal against the inner wall of the slide groove 111. In other embodiments, the protrusion 12 and the cabinet body 11 can also be detachably connected via other snap-fit ​​methods, or connected by bolts. If the cabinet body 11 and the protrusion 12 are non-detachable structures, they can also be directly welded together. The cabinet body 11 and the protruding body 12 can be made of the same material. The cabinet body is made of 1.2 mm thick stainless steel, with its core components being chromium (approximately 18%), nickel (approximately 8%), and carbon (approximately 0.08%), forming a stable austenitic stainless steel structure. This material has the following technical advantages and performance benefits: As the main structural component of the cabinet, this stainless steel material must bear the overall load of the equipment, including the weight of the internal fire extinguishing device 201, mechanical impacts from the external environment, and stress changes under extreme temperatures. Actual testing has verified that its tensile strength reaches over 520 MPa, far exceeding that of traditional ordinary carbon steel (the tensile strength of ordinary carbon steel is typically in the range of 370-460 MPa). This high-strength characteristic ensures that the cabinet will not fail due to structural deformation or breakage during long-term use, making it particularly suitable for scenarios with stringent requirements for equipment stability, such as chemical and power industries. The explosion-proof fire extinguishing cabinet 100 must maintain its structural integrity in high-temperature environments such as fires to prevent the cabinet from melting or deforming and affecting the activation and operation of the fire extinguishing device 201. The chromium in this stainless steel material forms a dense chromium oxide passivation film on the surface, while nickel enhances the material's high-temperature strength and toughness. The synergistic effect of these two elements gives the cabinet excellent high-temperature stability. In simulated fire tests, the cabinet maintained its structural integrity for one hour at 800℃, with a strength retention rate exceeding 85%. This effectively solves the technical problem of traditional materials experiencing a sharp drop in strength at high temperatures, leading to equipment malfunction. Ordinary carbon steel is susceptible to corrosion from environmental humidity, acidic or alkaline gases, and other factors. Rust products not only weaken the material but can also clog the cabinet's heat dissipation vents and interfere with the triggering mechanism of the fire extinguishing device 201, ultimately causing structural failure. However, this stainless steel material, thanks to the corrosion-resistant properties of chromium and nickel, can withstand long-term corrosion from moisture, salt spray, and weak acid / alkaline environments. After a salt spray test (5% NaCl solution, 35℃, 1000 hours), no obvious rust marks were observed on the surface. This characteristic fundamentally solves the structural failure problem caused by rust in traditional equipment, significantly extending the equipment's service life and improving overall safety and reliability.Compared to traditional carbon steel cabinets, this stainless steel structure achieves the following breakthroughs: a strength breakthrough, with tensile strength increased by over 30%, meeting the demands of high-load structures; a breakthrough in environmental adaptability, combining high-temperature stability and corrosion resistance to adapt to extreme working conditions; and a breakthrough in maintenance costs, eliminating the need for additional anti-corrosion coatings, reducing later maintenance costs and decreasing equipment failure rates due to rust. In summary, this stainless steel structure design not only fulfills the cabinet's supporting function but also, through optimized material properties, solves the structural failure problems of traditional fire extinguisher cabinets caused by rust and insufficient high-temperature strength. It provides a reliable guarantee for the long-term stable operation and safety protection of the equipment, representing the core innovation in the design of the explosion-proof fire extinguisher cabinet 100.

[0052] Furthermore, such as Figure 2 , Figure 10 As shown, a mounting rail 13 is provided on the wall surface of the protruding body 12, and the fire extinguishing module 4 and the surge module 5 are mounted on the mounting rail 13. The fire extinguishing module 4 and the surge module 5 are independent modules. The fire extinguishing module 4 is provided with a fire extinguishing mounting seat 8, which is connected to the mounting rail 13. The surge module 5 is provided with a surge mounting seat 9, which is connected to the mounting rail 13.

[0053] In this embodiment, the fire extinguishing mounting base 8 and the surge mounting base 9 have roughly the same structure. The fire extinguishing mounting base 8 will be used as an example for explanation. The side of the fire extinguishing mounting base 8 away from the fire extinguishing module 4 has a first latching position 81 for the mounting rail 13 to be inserted. The first latching position 81 can be a recessed area into which the mounting rail 13 is inserted.

[0054] In addition, such as Figure 10 , Figure 11 As shown, a first latching member 82 is provided on the side of the fire extinguishing mounting base 8 opposite to the fire extinguishing module 4. The first latching member 82 is used to lock the mounting rail 13. The fire extinguishing module 4 and the fire extinguishing mounting base 8 can be detachably connected or fixedly connected.

[0055] Furthermore, such as Figure 10 , Figure 11 As shown, the first fastener 82 is slidably connected to the fire extinguishing mounting base 8, and the first fastener 82 can be operably slid along the height direction of the fire extinguishing module 4.

[0056] In addition, such as Figure 10 , Figure 11 As shown, the top surface of the first latching position 81 has a protrusion 810. The first latching position 81 is used for the external mounting rail 13 to be latched in. The protrusion 810 cooperates with the first latching member 82 to latch the mounting rail 13.

[0057] Furthermore, such as Figure 10 , Figure 11 , Figure 12As shown, the fire extinguishing module 4 has a fire extinguishing top surface 41, a fire extinguishing bottom surface 42 opposite to the fire extinguishing top surface 41, a pair of fire extinguishing side surfaces 43 opposite to each other, a fire extinguishing front surface 44 connecting the pair of fire extinguishing side surfaces 43, and a fire extinguishing back surface 45 opposite to the fire extinguishing front surface 44. A top spray nozzle 46 is provided on the fire extinguishing top surface 41, and both the fire extinguishing top surface 41 and the fire extinguishing bottom surface 42 have heat-sensitive lines 47 extending from them. A bottom spray nozzle is also provided on the fire extinguishing bottom surface 42. The direction from the fire extinguishing top surface 41 to the fire extinguishing bottom surface 42 is the height direction of the fire extinguishing module 4.

[0058] Furthermore, such as Figure 10 , Figure 11 , Figure 12 As shown, the fire extinguishing mounting base 8 has a second latching position 83 on the side facing the fire extinguishing module 4 for the fire extinguishing module 4 to be engaged. The fire extinguishing mounting base 8 is provided with a second latching member 84 on the side facing the fire extinguishing module 4, which is used to engage with the top spray nozzle 46 of the fire extinguishing module 4.

[0059] Furthermore, such as Figure 10 , Figure 11 , Figure 12 As shown, the second fastener 84 is slidably connected to the fire extinguishing mounting base 8, and the second fastener 84 can be operably slid along the height direction of the fire extinguishing module 4, and when the second fastener 84 slides down to the preset position, it engages with the top spray nozzle 46.

[0060] In addition, such as Figure 10 , Figure 11 , Figure 12 As shown, each of the edges of the pair of fire-extinguishing sides 43 has a protruding edge 430, and each of the pair of sides of the fire-extinguishing mounting base 8 has a limiting groove 85. When the fire-extinguishing device 201 is engaged in the second latching position 83, the pair of protruding edges 430 respectively embed into the corresponding limiting grooves 85, and the pair of protruding edges 430 cooperate to clamp the fire-extinguishing mounting base 8. This prevents the fire-extinguishing module 4 from moving left or right, that is, prevents the fire-extinguishing module from moving along the direction of the pair of fire-extinguishing sides 43.

[0061] In addition, such as Figure 10 , Figure 11 , Figure 12 As shown, the first latching member 82 and the second latching member 84 are located below and above the first latching position 81, respectively. That is, in this embodiment, the first latching member 82 moves downwards to engage with the top spray nozzle 46, and the second latching member 84 moves upwards to engage with the mounting rail 13. The first latching member 82 and the second latching member 84 can be guide rail latches. In other embodiments, the first latching member 82 and the second latching member 84 can also be latching members positioned stationary on the fire extinguishing mounting base 8, using their slight elasticity to engage the mounting rail 13 and the fire extinguishing module 4.

[0062] In this example, the fire extinguishing module 4 and the surge module 5 are independent modules. The fire extinguishing module 4 is equipped with a fire extinguishing mounting base 8, and the surge module 5 is equipped with a surge mounting base 9. In other embodiments, such as Figure 13 The fire extinguishing module 4 and surge module 5 can be an integrated fire extinguishing and surge module 101, such as... Figure 14 Taking the device as an example, five modules are connected as a whole, one of which is the fire extinguishing module 4, and the other four are surge modules 5. The integrated fire extinguishing and surge module 101 is equipped with a mounting base, which is connected to the mounting rail 13. The structure of this mounting base is roughly the same as that of the fire extinguishing mounting base 8, and will not be described in detail here.

[0063] Furthermore, such as Figure 3 , Figure 4 As shown, the inner surface of the cabinet has an inner protective layer 14, which includes an outer layer 141, a middle layer 142, and an inner layer 142 stacked sequentially from the outside to the inside of the cabinet. The outer layer 141 includes mineral fiber felt, providing mechanical strength and thermal insulation; the middle layer 142 includes a bromine-containing composite material; and the inner layer 142 includes a microcapsule fire-extinguishing coating, which can actively extinguish fires. The outermost shell of the cabinet can be made of stainless steel, and the inner protective layer 14 is attached to the inner surface of the stainless steel.

[0064] Furthermore, the intermediate layer 142 is bonded and fixed to the inner layer 142 and the outer layer 141. The intermediate layer 142 is bonded to the inner layer 142 and the outer layer 141 with a high-temperature resistant adhesive, thereby enhancing the interfacial adhesion. The bromine content of the bromine-containing composite material ranges from 14% to 16%, preferably 15.2%. Bromine-containing composite materials can be categorized as follows: Brominated butyl rubber adhesives: These adhesives use brominated butyl rubber as the main raw material and contain two formulation components, A and B. Component A contains lead dioxide, and component B contains p-benzoquinone dioxime. Both components contain zinc oxide, stearic acid, and gasoline as solvents. They are mixed in a 1:1 ratio before use. This adhesive uses a heat-curing method and is suitable for bonding silicone to other materials in applications such as sealants and road / bridge vibration damping. Brominated epoxy resin adhesives: Brominated epoxy resins possess excellent electrical insulation, adhesion, and flame retardancy. They are widely used in electronics, building materials, composite materials, and flame retardant treatment of engineering plastics. When the bromine content in the epoxy resin reaches 16% or more, it exhibits good self-extinguishing properties. The higher the bromine content, the better the flame retardant performance. Tetrabromophthalic anhydride diol modified adhesives: Tetrabromophthalic anhydride diol, as a reactive flame retardant, is mainly used for flame retardant treatment of rigid polyurethane foam, adhesives, and coatings. Its bromine content is ≥44.0%, exhibiting high flame retardant efficiency. Brominated SBS modified adhesives: Brominated SBS can be used as a crosslinking agent and curing agent in the adhesive field, which can improve the bonding strength, weather resistance and corrosion resistance of adhesives. Its molecular structure makes it well dispersed in the matrix material and can effectively form a flame-retardant protective layer. Decabromodiphenyl ether added flame-retardant adhesives: Decabromodiphenyl ether is a general flame retardant with a bromine content as high as 83.3%. It can be used in various plastics, rubbers, unsaturated resins, adhesives, coatings, etc. It has a significant synergistic effect when used with antimony trioxide, and the flame-retardant performance is even higher. Polybrominated diphenyl ethers (PBDEs) adhesives: These include 209 homologues such as tetrabromodiphenyl ether, pentabromodiphenyl ether, hexabromodiphenyl ether, octabromodiphenyl ether, and decabromodiphenyl ether. As a commercial product, PBDEs are a mixture of diphenyl ethers with different numbers of bromine atoms. They have flame-retardant effects, but may pose environmental and health risks.

[0065] Specifically, the microcapsule dispersion treatment method involves mixing the microcapsules and the composite layer with a bromine-containing composite high-temperature resistant adhesive, followed by ultrasonic dispersion for 30 minutes to prevent agglomeration. The mineral fiber felt pretreatment methods include: surface activation: oxygen plasma treatment or silane coupling agent coating to enhance adhesion to the microcapsule layer; pore sealing treatment: spraying a pore-sealing agent (such as phenolic resin) onto the pores of the rock wool felt to prevent microcapsule penetration; composite process implementation: immersing the mineral fiber felt in the microcapsule suspension, vacuum degassing, drying (70℃, 5 hours), and using high-pressure airless spraying to uniformly cover the felt surface with a microcapsule coating thickness of 2.0 mm. Hot pressing is then performed at 120℃ and 1–2 MPa pressure for 30 minutes to form a dense interface, followed by room temperature curing for 24 hours or accelerated curing at 150℃ for 2 hours to ensure complete cross-linking of the adhesive.

[0066] In this embodiment, the inner lining layer is a high-performance composite fireproof material that combines passive fire protection (mineral fiber felt insulation and bromine-containing composite material flame retardancy) and active fire extinguishing (microcapsule release of extinguishing agent). It can actively intervene in the initial development of a fire, suppress the spread of flames, and ensure the structural integrity of the cabinet. The outer layer 141 mineral fiber felt and the inner layer 142 adhesive work together to improve the mechanical strength and impact resistance of the cabinet. The hot-pressing process ensures a tight bond between the layers, making it less prone to delamination and cracking under explosive impact. At the same time, the active fire extinguishing function can quickly reduce the pressure inside the cabinet. However, in the prior art, traditional fireproof materials only have passive fire protection functions, relying on the flame retardancy of the material itself to delay the spread of fire, but cannot actively extinguish fires. This has limited improvement on the pressure resistance of the explosion-proof cabinet. Traditional fireproof materials (such as rock wool boards) have low strength and are brittle, easily falling off under explosive impact, and cannot effectively maintain the integrity of the cabinet. PVC rolls have poor impact resistance and are prone to damage to the cabinet. Traditional fire extinguishing materials are based on active fire extinguishing (such as dry powder and gaseous fire extinguishing agent spraying), which can quickly extinguish open flames, but they do not provide continuous fire protection and may cause secondary damage to the internal structure of the cabinet and the stored items. Fire extinguishing equipment (such as sprinkler systems) may generate additional pressure fluctuations during the spraying process, which may increase the risk of explosion and cannot provide structural support for the cabinet, making it difficult to meet explosion-proof requirements.

[0067] Another embodiment of the present invention relates to a fire extinguishing device 201, such as Figure 11 , Figure 12 As shown, the fire extinguishing device 201 can be used in the aforementioned explosion-proof fire extinguishing cabinet 100 (e.g. Figure 2 (in the middle). The fire extinguishing device 201 includes: a fire extinguishing module 4 and a fire extinguishing mounting base 8. The fire extinguishing module 4 has a heat-sensitive wire 47 and a top spray nozzle 46. The fire extinguishing module 4 and the fire extinguishing mounting base 8 are detachably connected. The side of the fire extinguishing mounting base 8 opposite to the fire extinguishing module 4 has a first latching position 81.

[0068] Because a fire extinguishing mounting base 8 is provided, the fire extinguishing module 4 is installed through the fire extinguishing mounting base 8 to form a fire extinguishing device 201. This allows the fire extinguishing device 201 to be installed independently in the mounting rail 13 of the explosion-proof fire extinguishing cabinet 100, instead of directly fixing the fire extinguishing module 4 to the cabinet body of the explosion-proof fire extinguishing cabinet 100. This makes installation easier and more flexible. In addition, the fire extinguishing module 4 or the fire extinguishing device 201 can be disassembled and replaced during later maintenance, which is convenient for repair and replacement.

[0069] Furthermore, such as Figure 11 , Figure 12As shown, the fire extinguishing module 4 has a fire extinguishing top surface 41, a fire extinguishing bottom surface 42 opposite to the fire extinguishing top surface 41, a pair of fire extinguishing side surfaces 43 opposite to each other, a fire extinguishing front surface 44 connecting the pair of fire extinguishing side surfaces 43, and a fire extinguishing back surface 45 opposite to the fire extinguishing front surface 44. A top spray nozzle 46 is opened on the fire extinguishing top surface 41, and both the fire extinguishing top surface 41 and the fire extinguishing bottom surface 42 have heat-sensitive wires 47 extending from them.

[0070] Furthermore, the fire extinguishing mounting base 8 has a second latching position 83 on the side facing the fire extinguishing module 4 for the fire extinguishing module 4 to be engaged. The fire extinguishing mounting base 8 is provided with a second latching member 84 on the side facing the fire extinguishing module 4, which is used to engage with the top spray nozzle 46 of the fire extinguishing module 4.

[0071] Furthermore, the second fastener 84 is slidably connected to the fire extinguishing mounting base 8, and the second fastener 84 can be operably slid along the height direction of the fire extinguishing module 4, and when the second fastener 84 slides down to the preset position, it engages with the top spray nozzle 46.

[0072] In addition, each of the two fire-extinguishing side surfaces 43 has a protruding edge 430, and each of the two side surfaces of the fire-extinguishing mounting base 8 has a limiting groove 85. When the fire-extinguishing device 201 is engaged in the second latching position 83, the two protruding edges 430 respectively embed into the corresponding limiting grooves 85, and the two protruding edges 430 cooperate to clamp the fire-extinguishing mounting base 8. This prevents the fire-extinguishing module 4 from moving left or right.

[0073] Furthermore, a first latching member 82 is provided on the side of the fire extinguishing mounting base 8 opposite to the fire extinguishing module 4. The first latching member 82 is used to lock the mounting rail 13. The fire extinguishing module 4 and the fire extinguishing mounting base 8 can be detachably connected or fixedly connected.

[0074] Furthermore, the first fastener 82 is slidably connected to the fire extinguishing mounting base 8, and the first fastener 82 can be operably slid along the height direction of the fire extinguishing module 4. The height direction of the fire extinguishing module 4 is the direction from the top surface 41 of the fire extinguishing module 41 to the bottom surface 42 of the fire extinguishing module 4.

[0075] In addition, the top surface of the first latching position 81 has a protrusion 810. The first latching position 81 is used for the external mounting rail 13 to be latched in. The protrusion 810 cooperates with the first latching member 82 to latch the mounting rail 13.

[0076] Additionally, the first latching member 82 and the second latching member 84 are located below and above the first latching position 81, respectively. That is, in this embodiment, the first latching member 82 moves downwards to engage with the top spray nozzle 46, and the second latching member 84 moves upwards to engage with the mounting rail 13. The first latching member 82 and the second latching member 84 can be guide rail latches. In other embodiments, the first latching member 82 and the second latching member 84 can also be latching members positioned stationary on the fire extinguishing mounting base 8, using their slight elasticity to engage the mounting rail 13 and the fire extinguishing module 4.

[0077] It is not difficult to see that this embodiment corresponds to the first embodiment, and this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and will not be repeated here to reduce repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.
