Description

Technical Field

[0001] This application relates to the field of fire protection, and in particular to gas extinguishing systems. Background Technology

[0002] A gas extinguishing system refers to a fire extinguishing system in which the extinguishing agent is stored in a pressure vessel in liquid, liquefied gas, or gaseous state under normal conditions, and is sprayed as a gaseous (including vapor and aerosol) medium during fire extinguishing. It can form a uniform gas concentration in all directions within the protected space and maintain the extinguishing concentration for at least the impregnation time specified in the regulations to extinguish spatial and three-dimensional fires in the protected area.

[0003] The invention patent with announcement number CN116920298A proposes a high-efficiency gas fire extinguishing system, which includes several gas nozzles and smoke detectors, as well as a modular floor and a modular ceiling panel on which the gas nozzles and smoke detectors are installed. The modular ceiling panel is provided with a fireproof barrier cloth. When the smoke detectors detect smoke, the fireproof barrier cloth falls downwards and the lower end of the fireproof barrier cloth is fixed to the modular floor to create a closed area.

[0004] One of the aforementioned high-efficiency gas fire suppression systems uses gas nozzles to extinguish the fire in a single cabinet when one of the cabinets catches fire, reducing the cost of fire suppression. However, most cabinet fires are caused by the combustion of internal electrical components, and the gas nozzles cannot easily reach the inside of the cabinet when extinguishing the fire, resulting in a reduced fire suppression effect. Utility Model Content

[0005] To address the aforementioned issues, this application provides a gaseous fire extinguishing system.

[0006] The gaseous fire extinguishing system provided in this application adopts the following technical solution:

[0007] A gas extinguishing system includes a cabinet with an extinguishing assembly. The extinguishing assembly includes a through groove at the top of the cabinet. Connecting plates are fixedly connected to both sides of the through groove at the top of the cabinet. A connecting column is rotatably connected between the two connecting plates. The connecting column is vertically positioned with its bottom end inside the cabinet. A gas nozzle is installed at the bottom end of the connecting column. A connecting pipe communicating with the gas nozzle is fixedly connected to the top end of the connecting column. The cabinet is equipped with a push-pull assembly for swinging the connecting column and a gas supply assembly for supplying extinguishing gas. A smoke sensor for controlling the gas supply assembly is installed on one side wall at the bottom end of the connecting column.

[0008] By adopting the above technical solution, when a fire occurs in the electrical components inside the cabinet, the smoke sensor detects the smoke and the gas supply component delivers gas to the gas nozzle. The gas nozzle then sprays the extinguishing gas into the cabinet to extinguish the fire. At the same time, the push-pull component controls the connecting column to swing, allowing the gas nozzle to swing back and forth inside the cabinet, increasing the spray range and improving the extinguishing effect. This avoids the problem that most cabinet fires are caused by the combustion of internal electrical components, making it difficult for the gas nozzle to reach the inside of the cabinet and thus reducing the extinguishing effect.

[0009] Preferably, the push-pull assembly includes an electric push rod rotatably connected to the top of the cabinet, a U-shaped frame fixedly connected to the output end of the electric push rod, a push-pull rod rotatably connected to the opposite side wall of the U-shaped frame, and arc-shaped guide grooves provided on the side walls of the connecting plate. The push-pull rods pass through the arc-shaped guide grooves and are fixedly connected to the connecting column.

[0010] By adopting the above technical solution, the electric push rod is activated to reciprocate and push the U-shaped frame, which in turn drives the push-pull rod to move within the arc-shaped guide groove, causing the connecting column to swing within the through groove, thereby increasing the spray range of the gas nozzle.

[0011] Preferably, the gas supply assembly includes a gas tank installed on one side wall of the cabinet, a gas delivery hose is fixedly connected to the gas outlet end of the gas tank, the end of the gas delivery hose away from the gas tank is fixedly connected to the connecting pipe, a solenoid valve is installed at the gas outlet end of the gas tank, and the smoke sensor is electrically connected to the solenoid valve and the electric push rod.

[0012] By adopting the above technical solution, when the smoke sensor detects smoke, the solenoid valve is opened to allow the fire extinguishing gas stored in the gas tank to be delivered to the connecting pipe through the gas delivery hose, and then sprayed out by the gas nozzle to extinguish the fire inside the cabinet. At the same time, the electric push rod can be automatically activated to swing the gas nozzle.

[0013] Preferably, a fire extinguishing airbag is fixedly connected to the bottom of the cabinet.

[0014] By adopting the above technical solution, when a fire breaks out inside the cabinet and the fire source falls onto the fire extinguishing airbag, the fire extinguishing airbag is burned by the fire source, which can release the fire extinguishing gas inside the fire extinguishing airbag and improve the fire extinguishing effect on the cabinet.

[0015] Preferably, a grid plate is fixedly connected to the bottom of the cabinet inside, above the fire extinguishing airbag.

[0016] By adopting the above technical solution, electrical components can be easily installed inside the cabinet using the grille, preventing the fire extinguishing airbag from being pressed and damaged.

[0017] Preferably, the two side walls of the connecting column are fixedly connected with semi-circular baffles that are adapted to the through groove.

[0018] By adopting the above technical solution, the semi-circular baffle can seal the gap between the connecting column and the through groove while the connecting column swings, preventing dust and other debris from falling into the cabinet.

[0019] Preferably, a mounting base is fixedly connected to one side wall of the cabinet, and a mounting groove is provided at the top of the mounting base, into which the gas tank is inserted.

[0020] By adopting the above technical solution, the gas storage tank can be easily and quickly disassembled and assembled through the mounting base and mounting slot, and the gas storage tank can be regularly inspected and replaced.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the coordinated design of structures such as through channels, connecting plates, and connecting columns. During use, when a fire occurs in the electrical components inside the cabinet, the smoke sensor detects the smoke, prompting the gas supply assembly to deliver gas to the gas nozzle. The gas nozzle then sprays the extinguishing gas into the cabinet to extinguish the fire. Simultaneously, the push-pull assembly controls the connecting column to swing, allowing the gas nozzle to swing back and forth within the cabinet, increasing the spray range and enhancing the extinguishing effect. This avoids the problem that most cabinet fires are caused by the combustion of internal electrical components, making it difficult for the gas nozzle to reach the cabinet and thus reducing the extinguishing effect.

[0023] 2. When a fire breaks out inside the cabinet and the fire source falls onto the fire extinguishing airbag, the fire extinguishing airbag is burned and ruptured by the fire source, which allows the fire extinguishing gas inside the airbag to be discharged, improving the fire extinguishing effect on the cabinet.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a gaseous fire extinguishing system.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A gas extinguishing system includes a cabinet 1, on which extinguishing components are provided. The extinguishing components include a through groove 2, a connecting plate 3, a connecting column 4, a gas nozzle 5, a connecting pipe 6, and a smoke sensor 7.

[0032] The through slot 2 is located at the top of the cabinet 1. Two connecting plates 3 are fixedly connected to the top of the cabinet 1 and located on both sides of the through slot 2. The connecting column 4 is located above the cabinet 1 and has rotating rods fixedly connected to its two side walls. The ends of the two rotating rods away from the connecting column 4 pass through the two connecting plates 3 and form a rotating connection. The connecting column 4 is vertically set and its bottom end passes through the through slot 2 and is located inside the cabinet 1. The gas nozzle 5 is installed at the bottom of the connecting column 4. The connecting pipe 6 is fixedly connected to the top of the connecting column 4 and communicates with the gas nozzle 5. The cabinet 1 is provided with a push-pull assembly for pushing the connecting column 4 to swing and a gas supply assembly for supplying fire extinguishing gas to the gas nozzle 5. The smoke sensor 7 is installed on one side wall at the bottom of the connecting column 4 and is used to control the gas supply assembly to supply fire extinguishing gas to the gas nozzle 5.

[0033] Reference Figure 1 and Figure 3 The push-pull assembly includes an electric push rod 8 rotatably connected to the top of the cabinet 1. A U-shaped frame 9 is fixedly connected to the output end of the electric push rod 8. A push-pull rod 10 is rotatably connected to the opposite side wall of the U-shaped frame 9. Arc-shaped guide grooves 11 are opened on the side walls of the connecting plate 3. The push-pull rods 10 pass through the arc-shaped guide grooves 11 and are fixedly connected to the connecting column 4. By starting the electric push rod 8, the electric push rod 8 reciprocates to push and pull the U-shaped frame 9, which drives the push-pull rod 10 to move in the arc-shaped guide groove 11, causing the connecting column 4 to swing in the through groove 2, which can improve the spraying range of the gas nozzle 5.

[0034] Reference Figure 1 and Figure 4The gas supply assembly includes a gas tank 12 installed on one side wall of the cabinet 1. A gas delivery hose 13 is fixedly connected to the gas outlet of the gas tank 12. The end of the gas delivery hose 13 away from the gas tank 12 is fixedly connected to the connecting pipe 6. A solenoid valve 19 is installed at the gas outlet of the gas tank 12. A smoke sensor 7 is electrically connected to the solenoid valve 19 and the electric push rod 8. When the smoke sensor 7 detects smoke, it controls the solenoid valve 19 to open, so that the fire extinguishing gas stored in the gas tank 12 can be delivered to the connecting pipe 6 through the gas delivery hose 13 and then sprayed out by the gas nozzle 5 to extinguish the fire inside the cabinet 1. At the same time, the electric push rod 8 can be automatically activated to swing the gas nozzle 5.

[0035] Reference Figure 1 A fire extinguishing airbag 14 is fixedly connected to the bottom of the cabinet 1. When a fire starts inside the cabinet 1 and the fire source falls onto the fire extinguishing airbag 14, the fire extinguishing airbag 14 is burned by the fire source, which can release the fire extinguishing gas inside the fire extinguishing airbag 14 and improve the fire extinguishing effect on the cabinet 1.

[0036] Reference Figure 1 A grid plate 15 is fixedly connected to the bottom of the cabinet 1 above the fire extinguishing airbag 14. The grid plate 15 facilitates the installation of electrical components inside the cabinet 1 and prevents the fire extinguishing airbag 14 from being pressed and damaged.

[0037] Reference Figure 1 and Figure 4 The two side walls of the connecting column 4 are fixedly connected with semi-circular baffles 16 that are compatible with the through groove 2. The semi-circular baffles 16 can seal the gap between the connecting column 4 and the through groove 2 while the connecting column 4 swings, preventing dust and other debris from falling into the cabinet 1.

[0038] Reference Figure 1 A mounting base 17 is fixedly connected to one side wall of the cabinet 1. The top of the mounting base 17 has a mounting groove 18. The gas tank 12 is inserted into the mounting groove 18. The mounting base 17 and the mounting groove 18 facilitate quick and easy disassembly and assembly of the gas tank 12, and allow for regular inspection and replacement of the gas tank 12.

[0039] The implementation principle of the gas fire extinguishing system in this application embodiment is as follows: When a fire occurs in the electrical components inside the cabinet 1 and the smoke sensor 7 detects smoke, the solenoid valve 19 is opened by controlling it. This allows the fire extinguishing gas stored in the gas tank 12 to be delivered to the connecting pipe 6 through the gas delivery hose 13. Then, the gas nozzle 5 sprays the gas into the cabinet 1 to extinguish the fire. At the same time, the electric push rod 8 is activated, causing it to reciprocate to push and pull the U-shaped frame 9. This drives the push rod 10 to move within the arc-shaped guide groove 11, causing the connecting column 4 to swing within the through groove 2. This increases the spray range of the gas nozzle 5 and improves the fire extinguishing effect. When the fire source inside the cabinet 1 falls onto the fire extinguishing airbag 14, the fire extinguishing airbag 14 is ruptured by the fire source, allowing the fire extinguishing gas inside the fire extinguishing airbag 14 to be discharged. This improves the fire extinguishing effect on the cabinet 1 and avoids the problem that most fires in the cabinet are caused by the combustion of internal electrical components, making it difficult for the gas nozzle 5 to reach the inside of the cabinet and thus reducing the fire extinguishing effect.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
