Description

Technical Field

[0001] This utility model belongs to the field of fire extinguishing equipment technology, specifically a fire extinguishing device that can achieve fixed-point protection of multiple cabinets. Background Technology

[0002] Perfluorohexanone is an important alternative to halon fire extinguishing agents. It is a fluorinated ketone compound, a clear, colorless, and odorless liquid with excellent environmental performance. Applications include fires in electrical rooms, computer rooms, data centers, ports, and aviation and ship power distribution rooms.

[0003] Currently, perfluorohexanone (PFH) fire extinguishing systems are commonly used in industrial power facilities due to their specific properties, such as high- and low-voltage switchgear (power supply stations, substations, etc.). Most fire extinguishing systems on the market are limited to individual protection of single cabinets. When protecting multiple cabinets or rows of cabinets in multiple spaces, multiple sets of fire extinguishing equipment or a complete fire extinguishing system needs to be installed. When installing a complete fire extinguishing system, if a fire breaks out in one cabinet, multiple cabinets will simultaneously spray the extinguishing agent, easily leading to agent waste. Furthermore, perfluorohexanone extinguishing agents are relatively expensive; if multiple cabinets spray the agent simultaneously, given sufficient extinguishing time, it will significantly increase the cost of agent usage, which does not meet the actual needs of customers. Utility Model Content

[0004] The purpose of this invention is to provide a fire extinguishing device that can achieve fixed-point protection for multiple cabinets, aiming to solve the problems of waste of chemical resources and increased usage costs.

[0005] To address the aforementioned technical problems, this utility model provides a fire extinguishing device capable of providing fixed-point protection for multiple cabinets, including a control box, a chemical agent cabinet, and multiple protective cabinets. Each of the protective cabinets has a temperature-sensitive fire extinguishing component installed on its inner top. A solenoid valve connected to the control box is provided on one side of the chemical agent cabinet. One end of the solenoid valve is connected to a main chemical agent pipe. Multiple chemical agent branch pipes, each corresponding to a protective cabinet, are provided on the main chemical agent pipe. One end of each chemical agent branch pipe is connected to a corresponding temperature-sensitive fire extinguishing component.

[0006] Preferably, the temperature-sensitive fire extinguishing assembly includes a temperature-sensitive magnetic power generation assembly, a control valve, and a nozzle. The input end of the control valve is connected to a first agent branch pipe, and the output end of the control valve is connected to the nozzle through a second agent branch pipe. One end of the control valve is connected to the temperature-sensitive magnetic power generation assembly through a feedback power supply harness, and the temperature-sensitive magnetic power generation assembly is connected to the control box through a feedback signal harness.

[0007] Preferably, the control valve includes a valve body, one side of which has a non-penetrating branch pipe mounting hole 1 connected to a drug branch pipe 1, the bottom of which has a drug channel 1, and the other side of which has a penetrating branch pipe mounting hole 2. The inner wall of the branch pipe mounting hole 2 is connected to the drug channel 1 through the drug channel 2, the bottom of which is connected to the drug branch pipe 2, and the top of which has an opening and closing assembly for controlling the opening and closing of the drug channel 2. The opening and closing assembly is connected to a feedback power supply harness.

[0008] Preferably, the opening and closing assembly includes a puncture-type actuating component and a diaphragm. The diaphragm is installed inside the second branch pipe mounting hole by a fixing nut. The puncture-type actuating component is installed at the top of the second branch pipe mounting hole and is directly opposite the diaphragm. The position height of the diaphragm is lower than the position height of the second drug channel.

[0020] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this utility model. It should also be noted in the description of this utility model that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1 to 4 As shown, this utility model provides a fire extinguishing device that can achieve fixed-point protection for multiple cabinets, including a control box 1, a chemical agent cabinet 2, and a protective cabinet 8. The protective cabinet 8 can be a single cabinet or a row of cabinets, such as high-voltage or low-voltage switch cabinets or computer cabinets. The inner top of the protective cabinet 8 is equipped with a temperature-sensitive fire extinguishing component and a nozzle 14, while the outer top of the chemical agent cabinet 2 is equipped with an audible and visual alarm 5 connected to the control box 1.

[0022] The interior of the agent cabinet 2 contains agent bottles and a nitrogen pressurization cylinder. The nitrogen pressurization cylinder contains high-pressure gas and is equipped with a pressure reducing valve on its upper part, which is connected to the filling switch of the agent bottle. The agent bottles contain fire extinguishing agents, and a solenoid valve controlled by the control box 1 is installed at the outlet of the agent bottle.

[0023] One end of the solenoid valve is connected to the main agent pipe 4 leading to the agent cabinet 2, and a plug 15 is installed at the end of the main agent pipe 4. Multiple control valves 9, each corresponding to a protective cabinet 8, are installed on the main agent pipe 4. These control valves 9 are connected to corresponding temperature-sensitive fire extinguishing components via agent branch pipes 10. A time controller is installed inside the control box 1, and the time controller is connected to the control valves 9 via a wiring harness. Based on the size of the protective cabinet 8, the time controller independently controls the spraying time by controlling the opening time of the corresponding control valves 9. The spraying time can be individually adjusted by the time controller; after the preset time is reached, the control valve 9 automatically closes to avoid agent waste.

[0024] The temperature-sensitive fire extinguishing assembly includes a temperature-sensing magnetic power generation component 6, a control valve 7, and a nozzle 14. The temperature-sensing magnetic power generation component 6 is connected to the control box 1 via a feedback signal harness 3. The control valve 7 includes a valve body. One side of the valve body has a non-penetrating branch pipe mounting hole 701 that connects to the agent branch pipe 10. The other side of the valve body has a penetrating branch pipe mounting hole 702, which is connected to the nozzle 14 via the agent branch pipe 13.

[0025] A chemical channel 703 is provided at the bottom of the branch pipe mounting hole 701. One side of the inner wall of the branch pipe mounting hole 702 is connected to the chemical channel 703 via the chemical channel 704. An opening / closing assembly for controlling the opening and closing of the chemical channel 704 is provided at the top of the branch pipe mounting hole 702. The opening / closing assembly includes a piercing starter 11 and a diaphragm 17. The piercing starter 11 is connected to the temperature-sensing magnetic power generation assembly 6 via a feedback power harness 12. The diaphragm 17 is installed inside the branch pipe mounting hole 702 using a fixing nut 16. The piercing starter 11 is installed at the top of the branch pipe mounting hole 702, directly opposite the diaphragm 17. The height of the diaphragm 17 is lower than the height of the chemical channel 704.

[0026] When a fire occurs inside one or more of the protective cabinets 8, the fire source inside the corresponding protective cabinet 8 is detected by the temperature-sensing magnetic power generation component 6. One path of the temperature-sensing magnetic power generation component 6 generates an instantaneous current, which is quickly transmitted to the puncture-type starting component 11 through the feedback power harness 12. The puncture-type starting component 11 is excited by the current, which quickly pushes the striking pin to move instantaneously. The striking pin punctures the diaphragm 17 in the control valve 7. At the same time, another path of the temperature-sensing magnetic power generation component 6 generates a switching feedback signal, which is transmitted to the control box 1 through the feedback signal harness 3. The control box 1 controls the solenoid valve to open, and the agent is delivered along the agent main pipe 4, agent branch pipe one 10, and agent branch pipe two 13, and released through the nozzle 14. The audible and visual alarm 5 sounds an alarm.

[0027] The embodiments described above are not exhaustive, nor do they limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, enabling those skilled in the art to effectively utilize the invention and its modifications. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the protection scope of the invention.
