Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a novel rack-mounted perfluorohexanone fire extinguishing device. Background Technology

[0002] Perfluorohexanone (PFH), as a highly efficient and environmentally friendly clean fire extinguishing agent, is widely used for fire protection in various precision equipment, electrical cabinets, data center racks, and other scenarios due to its high fire extinguishing efficiency, excellent insulation properties, no ozone depletion potential, and low greenhouse effect. Rack-mounted PPH fire extinguishing systems, designed for small, enclosed spaces, typically consist of a fire extinguishing agent storage container, activation components, spray lines, and heat or smoke detection elements. Their core principle is to extinguish initial fires by rapidly releasing PPH, utilizing the agent's heat absorption and cooling properties, and isolating oxygen, thus preventing the fire from spreading and damaging equipment.

[0003] With the rapid development of industrial automation and data center construction, the integration of rack-mounted equipment is constantly increasing, leading to a corresponding increase in the fire risk of internal circuits and components. Traditional rack-mounted fire suppression systems mostly rely on automatic activation, meaning that the release of fire extinguishing agents is automatically triggered after a fire is detected by detection elements. This automatic activation mode can quickly respond to initial fires in unattended scenarios, offering a certain degree of timeliness and convenience.

[0004] However, in practical applications, automatic activation systems may fail to activate reliably due to factors such as detector component malfunction (e.g., false alarms, delayed alarms), environmental interference (e.g., dust, high-temperature steam), or specific fire types (e.g., smoldering fires not being detected in time). In such cases, manual assessment of the fire situation and manual activation of the extinguishing device can effectively compensate for the shortcomings of the automatic system and improve the success rate of fire suppression. However, existing rack-mounted perfluorohexanone (PFH) extinguishing devices generally lack a reliable manual activation function. This results in the inability to achieve convenient and reliable manual activation during use, leading to difficulties in effectively extinguishing initial fires when the automatic activation system fails, and failing to meet the needs of actual emergency scenarios. Therefore, there is an urgent need for a new type of rack-mounted PPH extinguishing device that can be both automatically and easily manually activated. Utility Model Content

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] Example:

[0040] like Figures 1 to 8As shown, this embodiment discloses a novel rack-mounted perfluorohexanone fire extinguishing device, including a mounting box 10, a fire extinguishing agent storage component 11, and a fire extinguishing agent release component 12. The fire extinguishing agent storage component 11 and the fire extinguishing agent release component 12 are disposed inside the mounting box 10, and the fire extinguishing agent storage component 11 is connected to the fire extinguishing agent release component 12.

[0041] The extinguishing agent release assembly 12 includes a multi-functional nozzle 13 and a manual triggering structure 14. The multi-functional nozzle 13 includes a discharge valve body 15, a nozzle assembly 16, an electric drive structure 17, and a temperature sensing structure 18. The discharge valve body 15 is located at the bottom of the mounting box 10, and one end of the discharge valve body 15 penetrates through the mounting box 10. The discharge valve body 15 is detachably connected to the mounting box 10. The electric drive structure 17 is located at the top of the discharge valve body 15. The nozzle assembly 16 is located at the lower end of the discharge valve body 15. The temperature sensing structure 18 is located at the bottom of the discharge valve body 15. The mounting box 10 is provided with a wiring terminal 19. The wiring terminal 19 is embedded in the top of the mounting box 10 and is detachably connected to the mounting box 10. The electric drive structure 17 is electrically connected to the wiring terminal 19. The wiring terminal 19 can be connected to an external power source.

[0042] The manual trigger structure 14 includes a battery pack 20 and a manual start button 21. The battery pack 20 is detachably connected to the mounting housing 10 and electrically connected to the electric drive structure 17. The manual start button 21 is embedded in the top of the mounting housing 10 and is fixedly connected to the top of the mounting housing 10. The manual start button 21 is used to control the battery pack 20 to supply power to the electric drive structure 17.

[0043] Compared to traditional rack-mounted perfluorohexanone fire extinguishing devices, this invention adds a manual triggering structure 14, providing an additional manual activation path. In use, when a fire is discovered manually, and the electric drive structure 17 and temperature sensing structure 18 have not automatically triggered, the manual activation button 21 can be pressed manually. This activates the battery pack 20 to provide starting current to the electric drive structure 17, thereby releasing the extinguishing agent. This solves the problem that current rack-mounted perfluorohexanone fire extinguishing devices, due to the lack of convenient and reliable manual activation, struggle to effectively extinguish initial fires when the automatic activation system fails, thus failing to meet the needs of actual emergency scenarios.

[0044] The connection circuit between the manual start button 21, the battery pack 20, and the electric drive structure 17 is existing technology and will not be described in detail. The external power supply connected to the terminal 19 is the current generated after the external alarm is triggered, typically 24V, 1.5A.

[0045] To facilitate the control of extinguishing agent release, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the main body 15 of the discharge valve is provided with an installation cavity 22, which runs through the main body 15 of the discharge valve from top to bottom. The installation cavity 22 includes an upper cavity 23 and a lower cavity 24 that are connected. A sealing piston 25 is provided in the lower cavity 24. The sealing piston 25 slides and is sealed to the lower cavity 24. A flow cavity 26 is provided in the sealing piston 25. A groove 27 is provided on the outside of the sealing piston 25. A plurality of flow ports 28 communicating with the flow cavity 26 are provided in the groove 27. An installation groove 29 communicating with the flow cavity 26 is provided on the top of the sealing piston 25. A sealing diaphragm 30 and a diaphragm pressure ring 31 are provided in the installation groove 29. The diaphragm pressure ring 31 is located above the sealing diaphragm 30 and is threadedly connected to the installation groove 29 to fix the sealing diaphragm 30 in the installation groove 29.

[0046] The nozzle assembly 16 includes a plurality of atomizing nozzles 32, which are respectively disposed at the lower end of the discharge valve body 15 and communicate with the lower cavity 24. The plurality of atomizing nozzles 32 are threadedly connected to the discharge valve body 15.

[0047] The temperature sensing structure 18 includes a temperature sensing glass ball 33 and a protective cover 34. One end of the protective cover 34 is fixedly connected to the bottom of the discharge valve body 15. The protective cover 34 is provided with several windows 35. The bottom of the protective cover 34 is provided with a fixing plate 36, which is threadedly connected to the protective cover 34. The temperature sensing glass ball 33 is placed inside the protective cover 34. One end of the temperature sensing glass ball 33 abuts against the fixing plate 36, and the other end abuts against the piston to support the sealing piston 25.

[0048] The temperature-sensing glass ball 33 can be selected according to actual needs, and the temperature-sensing glass ball 33 is existing technology.

[0049] In use, when the temperature-sensing glass bulb 33 cracks due to heat, the sealing piston 25 loses its support and slides downward under the push of the extinguishing agent, allowing the extinguishing agent to be sprayed from several atomizing nozzles 32 to extinguish the fire. The atomizing nozzles are designed to better cover the fire point when the extinguishing agent is sprayed.

[0050] To further facilitate the control of extinguishing agent release, this embodiment is an improvement on the above embodiment. The difference lies in that the electrically driven structure 17 includes a mounting housing 37, a needle body 38, a support spring 39, a locking head 40, and a connector 41. The mounting housing 37 is located on top of the discharge valve body 15 and is threadedly connected to the upper cavity 23. The mounting housing 37 contains a receiving cavity 42. The support spring 39 and the needle body 38 are disposed within the receiving cavity 42. One end of the support spring 39 contacts the needle body 38, and the other end contacts the bottom of the receiving cavity 42. One end of the needle body 38 passes through the support spring 39 and penetrates... The bottom of the mounting housing 37 extends into the upper cavity 23. The needle body 38 is slidably connected to the bottom of the mounting housing 37. One end of the needle body 38 passes through the mounting housing 37 and is slidably engaged with the upper cavity 23, the lower cavity 24 and the diaphragm pressure ring 31 respectively. The locking head 40 is located at the top of the mounting housing 37. One end of the locking head 40 is located inside the mounting housing 37 and contacts the top of the needle body 38. A drug filling cavity 43 is provided between the locking head 40 and the needle body 38. A wiring cavity 44 communicating with the drug filling cavity 43 is provided on the locking head 40. The wiring head 41 is fixedly installed in the wiring cavity 44 and is electrically connected to the battery pack 20 and the terminal 19.

[0051] The needle body 38 includes a contact part 45, a connecting part 46, and a needle part 47 that are fixedly connected in sequence. The contact part 45 is slidably connected to the receiving cavity 42. One end of the support spring 39 contacts the bottom of the contact part 45. The connecting part 46 passes through the support spring 39 and extends through the bottom of the mounting housing 37 into the upper cavity 23. The connecting part 46 is slidably connected to the bottom of the mounting housing 37. One end of the connecting part 46 that passes through the mounting housing 37 is slidably engaged with the upper cavity 23 and the lower cavity 24 respectively. The needle part 47 is slidably engaged with the diaphragm pressure ring 31. The needle part 47 is used to puncture the sealing diaphragm 30.

[0052] When the starting current generated by the external alarm or the starting current provided by the battery pack 20 is transmitted to the terminal 41, the starting current triggers the agent in the agent filling chamber 43 to generate a large amount of gas, which in turn pushes the contact part 45, causing the needle body 38 to slide downward, thereby causing the needle part 47 to pierce the diaphragm, and then the extinguishing agent passes through the installation groove 29, the flow chamber 26, the flow port 28, the groove 27 and the lower chamber 24, and finally sprays out from the atomizing nozzle.

[0053] To facilitate the installation of the perfluorohexanone storage bottle 48 and to provide perfluorohexanone extinguishing agent to the multi-functional nozzle 13, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the extinguishing agent storage assembly 11 includes a pair of perfluorohexanone storage bottles 48. The pair of perfluorohexanone storage bottles 48 are fitted together and installed in the mounting box 10. The pair of perfluorohexanone storage bottles 48 are respectively connected to the mounting box 10 by a pair of clamps 49. The pair of clamps 49 are respectively installed on the perfluorohexanone storage bottles 48, and one end is detachably connected to the mounting box 10 by bolts. The output port of the pair of perfluorohexanone storage bottles 48 is connected through a first connecting copper pipe 50. The first connecting copper pipe 50 is provided with a three-way connector 51. The main body 15 of the discharge valve is provided with a liquid inlet 52 communicating with the upper cavity 23 on one side. A second connecting copper pipe 53 is provided on one side of the liquid inlet 52. One end of the second connecting copper pipe 53 is connected to the liquid inlet 52, and the other end is connected to the three-way connector 51.

[0054] The clamp 49 facilitates the installation of the perfluorohexanone storage bottle 48. The first connecting copper pipe 50, the tee connector 51, and the second connecting copper pipe 53 facilitate the supply of perfluorohexanone extinguishing agent to the multi-functional sprinkler head 13.

[0055] To facilitate testing during installation, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a three-way ball valve 54 is provided on the second connecting copper pipe 53. The three-way ball valve 54 is located at the bottom of the mounting box 10. A third connecting copper pipe 55 is provided at one end of the three-way ball valve 54. An external pressure interface 56 is provided at the bottom of the mounting box 10. One end of the third connecting copper pipe 55 is connected to the three-way ball valve 54, and the other end is connected to the external pressure interface 56.

[0056] The three-way ball valve 54 allows this invention to have three states: closed, standby, and maintenance. Closed means the three-way ball valve 54 is closed, and the second connecting copper pipes 53 at both ends of the three-way ball valve 54 and the third connecting copper pipe 55 at the other end of the three-way ball valve 54 are not connected. Standby means the second connecting copper pipes 53 at both ends of the three-way ball valve 54 are connected, while the third connecting copper pipe 55 is not connected. Maintenance means the third connecting copper pipe 55 is connected to the second connecting copper pipe 53 on the side of the three-way ball valve 54 closest to the discharge valve body 15.

[0057] To facilitate real-time monitoring of the extinguishing agent pressure, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a pressure interface 57 communicating with the upper cavity 23 is provided on one side of the discharge valve body 15, and a pressure gauge 58 is embedded in the top of the mounting box 10. The pressure gauge 58 is fixedly connected to the top of the mounting box 10. A fourth connecting copper pipe 59 is provided at one end of the pressure interface 57. One end of the fourth connecting copper pipe 59 is connected to the pressure interface 57, and the other end is connected to the pressure gauge 58.

[0058] The pressure gauge 58 allows for real-time monitoring of the extinguishing agent pressure, preventing the extinguishing device from malfunctioning due to insufficient pressure.

[0059] As a further preferred embodiment, a safety valve 61 communicating with the upper cavity 23 is provided on one side of the discharge valve body 15.

[0060] To facilitate the disassembly and assembly of various components, the front end of the mounting box 10 is provided with a mounting box cover 60 that is adapted to the mounting box 10, and the mounting box cover 60 is detachably connected to the mounting box 10.

[0061] The mounting cover 60 is detachably connected to the mounting box 10, which facilitates the disassembly and assembly of various components installed in the mounting box 10. At the same time, the mounting cover 60 can also protect the various components and wiring inside the mounting box 10.

[0062] Working principle of this utility model:

[0063] Compared to traditional rack-mounted perfluorohexanone fire extinguishing devices, this invention adds a manual triggering structure 14, providing an additional manual activation path. In use, when a fire is discovered manually, and the electric drive structure 17 and the temperature sensing structure 18 have not automatically triggered, the manual activation button 21 can be pressed manually. This activates the battery pack 20 to provide starting current to the electric drive structure 17, thereby releasing the extinguishing agent.
