Description

Technical Field

[0001] This invention relates to the field of fire suppression technology for computer rooms, and more particularly to a gas fire suppression system for computer rooms. Background Technology

[0002] Computer rooms, being hubs for precision electronic equipment, are prone to fires due to excessive loads, outdated equipment, and untimely replacements, as well as battery ignition. If a fire in a computer room is not dealt with promptly, it can cause significant damage. To prevent damage to internal equipment, gaseous fire extinguishers are typically used for fire suppression in computer rooms. The extinguishing agent in gaseous fire extinguishers has excellent insulating properties, is non-conductive, easily vaporizes, leaves no residue, and vaporizes completely in a very short time. Therefore, professional gaseous fire extinguishers should be used in computer rooms storing high-precision electronic equipment. However, existing gaseous fire extinguishers use a gaseous extinguishing agent that can easily diffuse outside the computer room, leading to waste and reduced extinguishing effectiveness. In particular, if the ventilation openings in the computer room are not properly sealed, a large amount of gas can escape, filling the building's ventilation system with smoke and dust. Current technology cannot effectively seal these ventilation openings, failing to address the technical problem of large gas leaks causing smoke and dust accumulation in the ventilation system.

[0003] A search revealed Chinese patent application CN220404672U, which discloses a gas fire suppression system for a computer room. The system includes a fire extinguishing agent container, electrically operated doors and windows located in the computer room, a fire extinguishing controller, smoke detectors, and heat detectors. The smoke and heat detectors are located on the ceiling of the computer room. The fire extinguishing agent container contains fire extinguishing agent and is equipped with an electrically operated valve. The valve is connected to a nozzle via a gas pipeline. The nozzles are positioned horizontally or downwards. A pressure relief device is installed inside the computer room. However, this patent cannot effectively seal the ventilation openings of the computer room, failing to address the problem of large amounts of gas leaking out and filling the building's ventilation system with smoke and dust. Summary of the Invention

[0004] This invention provides a computer room gas fire suppression system. The technical problem to be solved is that it is impossible to seal the ventilation openings of the computer room well, and it is impossible to solve the problem of a large amount of gas flowing out, causing the building ventilation system to be filled with smoke and dust.

[0009] As a preferred embodiment of the present invention: the recycling pipe is slidably connected to the sliding baffle in the groove on one side, and a spring is fixedly connected between the recycling pipe and the sliding baffle.

[0010] As a further embodiment of the present invention: guide ramps are fixedly connected to the upper and lower ends of the sliding baffle, an extrusion ramp is fixedly connected to one side of the material nozzle, and one side of the extrusion ramp is slidably connected to the guide ramp.

[0025] A computer room gas fire suppression system, such as Figures 1-9 As shown, the firewall body 1 includes a host 5 and a vent 7 installed inside. The firewall body 1 is a wall with heat insulation and flame retardant effect. Multiple fan blades 8 are rotatably connected to the inside of the vent 7. A duct 12 is fixedly connected to the rear of the vent 7. A translation component and a recovery pipe 25 are fixedly connected to the inside of the duct 12. A material nozzle 21 is drivenly connected to one end of the translation component. A feeding component is fixedly connected to one side of the material nozzle 21. A connecting pipe 26 is fixedly connected to the lower end of the recovery pipe 25. A recovery box 9 is fixedly connected to the lower end of the connecting pipe 26. One side of the recovery box 9 is fixedly connected to the firewall body 1. The feeding assembly includes a mixing assembly 16, a mixing tank 17, a paint pump 18, and a spray pipe 19. The upper end of the mixing assembly 16 is a motor part, and the lower end is a main shaft with a mixing paddle installed. The spray pipe 19 is fixedly connected to one side of the material nozzle 21. The spray pipe 19 is fixedly connected to the air outlet of the paint pump 18. One end of the inlet of the paint pump 18 is fixedly connected to the mixing tank 17 through a pipe. The mixing assembly 16 is fixedly connected to the top of the mixing tank 17. A partition 11 is fixedly connected to one side of the firewall body 1. A mixing box 13, a cleaning agent box 14, and a mixing box 2 15 are fixedly connected to one side of the partition 11. Preferably, the mixing box 13 contains isocyanate semi-prepolymer, and the mixing box 2 15 contains amino-terminated polyether. Electric switches 28 are fixedly connected to the bottom of the mixing box 13, the cleaning agent box 14, and the mixing box 2 15 through pipes. The multiple electric switches 28 are fixedly connected to the top of the mixing tank 17. When a fire occurs inside the firewall 1, multiple fan blades 8 inside the ventilation opening 7 rotate, thereby closing the ventilation opening 7. At this time, in order to prevent the ventilation opening 7 from being completely sealed by the fan blades 8 alone, the electric switches 28 at the lower end of the mixing box 13 and the mixing box 25 are opened, allowing the isocyanate semi-prepolymer and the amino-terminated polyether to enter the mixing tank 17. Then the mixing assembly 16 is started to mix the two. Then the paint pump 18 is started, and the mixed material is sprayed out from the material nozzle 21 with multiple nozzles at one end through the spray pipe 19. It can evenly cover the back side of the ventilation opening 7. In this way, the foam after mixing the isocyanate semi-prepolymer and the amino-terminated polyether can fill the gaps. The isocyanate semi-prepolymer and the amino-terminated polyether can be cured within a few minutes to a dozen minutes after mixing. The curing is accelerated in the hot environment of a fire. This can prevent the airflow from flowing out from the gaps between the ventilation opening 7 and the fan blades 8, allowing the smoke to spread in the duct 12 and affect the air in other areas of the building where the machine room is located. During the spraying process, the translation component can drive the material nozzle 21 to move slowly and repeatedly, so that the foam mixture can completely cover the rear side of the vent 7. After the slow reciprocating movement is repeated many times, in order to prevent the foam material in the mixing component 16, mixing tank 17, paint pump 18 and spray pipe 19 from solidifying and affecting reuse, the material nozzle 21 is moved to the opening on one side of the recovery pipe 25. At this time, the electric switch 28 below the cleaning agent box 14 is turned on, allowing the cleaning agent in the cleaning agent box 14 to flow into the mixing tank 17. The cleaning agent can be dichloromethane, acetone, or ethyl acetate. After the mixture on the mixing tank 17 and the mixing component 16 is stirred and dissolved, the paint pump 18 sprays the cleaning agent from one end of the spray pipe 19 and the material nozzle 21, and at the same time, the cleaning agent can clean the paint pump 18, the spray pipe 19, and the material nozzle 21 simultaneously. The recovery pipe 25 can prevent the sprayed cleaning agent from affecting the mixture behind the vent 7, and the sprayed cleaning agent is blocked and recovered into the recovery box 9 below the connecting pipe 26 for storage. There is a solenoid valve on the top of the recovery box 9, which can close the inlet to prevent evaporation from flowing into the air duct 12 when not in use.

[0026] like Figures 1-9 As shown, the translation component includes a drive motor 20, a lead screw 23, and a slide rod 24. The slide rod 24 is fixedly connected to the inner side of the air duct 12, the drive motor 20 is fixedly connected to the outer side of the air duct 12, the lead screw 23 is fixedly connected to the power output end of the drive motor 20, the lead screw 23 is threadedly connected to the lower end of the material nozzle 21, and the drive motor 20 is slidably connected to the material nozzle 21 above. The drive motor 20 can drive the material nozzle 21 to move back and forth by rotating in both directions using the lead screw 23 for spraying, and the slide rod 24 can stabilize the sliding of the material nozzle 21.

[0027] like Figures 1-9 As shown, the recycling pipe 25 is slidably connected to the sliding baffle 27 in the groove on one side, and a spring 30 is fixedly connected between the recycling pipe 25 and the sliding baffle 27; guide ramps 29 are fixedly connected to the upper and lower ends of the sliding baffle 27, and an extrusion ramp 31 is fixedly connected to one side of the material nozzle 21, and the extrusion ramp 31 is slidably connected to the guide ramp 29 on one side. The recovery tube 25 and the sliding baffle 27 can surround the front and sides of the material nozzle 21 to prevent the cleaning agent from being sprayed onto the mixture foam behind the vent 7. At the same time, the squeezing ramps 31 at the upper and lower ends of the material nozzle 21 can squeeze the sliding baffle 27 forward by the guide ramp 29 when the material nozzle 21 enters or exits the recovery tube 25, so that the material nozzle 21 can smoothly enter and exit the recovery tube 25. After the guide ramp 29 and the squeezing ramp 31 are separated, the sliding baffle 27 is reset by the spring 30 to achieve the blocking function.

[0028] like Figures 1-9 As shown, a second collection box 10 is fixedly connected to the bottom of the air duct 12 via a pipe, and a protective bracket 22 is fixedly connected to the air duct 12. There is a solenoid valve above the second collection box 10, which can collect the cleaning agent falling from the bottom of the air duct 12 and seal it after the device stops working to prevent the cleaning agent from evaporating. The protective bracket 22 can prevent the mixture foam from splashing onto the lead screw 23 when it is sprayed out.

[0029] In this embodiment, when a fire occurs inside the firewall 1, multiple fan blades 8 inside the ventilation opening 7 rotate, thereby closing the ventilation opening 7. To prevent the ventilation opening 7 from being completely sealed by the fan blades 8 alone, the electric switches 28 at the lower ends of mixing boxes 13 and 25 are opened, allowing the isocyanate semi-prepolymer and terminal amino polyether to enter the mixing tank 17. Then, the stirring assembly 16 is started to mix the two. Next, the paint pump 18 is started, spraying the mixed material through the spray pipe 19 from one end... The material from the nozzle 21 is sprayed out from one end and can evenly cover the back side of the vent 7. This allows the foam made from the mixture of isocyanate semi-prepolymer and amino-terminated polyether to fill the gaps. The mixture of isocyanate semi-prepolymer and amino-terminated polyether can be cured within a few minutes to a dozen minutes. In the hot environment of a fire, the curing will be accelerated. This can prevent airflow from flowing out from the gaps between the vent 7 and the fan blades 8, allowing smoke to spread in the duct 12 and affect the air in other areas of the building where the computer room is located. During the spraying process, the translation component can drive the material nozzle 21 to move slowly and repeatedly, so that the foam mixture can completely cover the rear side of the vent 7. After the slow reciprocating movement is repeated many times, in order to prevent the foam material in the mixing component 16, mixing tank 17, paint pump 18 and spray pipe 19 from solidifying and affecting reuse, the material nozzle 21 is moved to the opening on one side of the recovery pipe 25. At this time, the electric switch 28 below the cleaning agent box 14 is turned on, allowing the cleaning agent in the cleaning agent box 14 to flow into the mixing tank 17. The cleaning agent can be dichloromethane, acetone, or ethyl acetate. After the mixture on the mixing tank 17 and the mixing component 16 is stirred and dissolved, the paint pump 18 sprays the cleaning agent from one end of the spray pipe 19 and the material nozzle 21, and at the same time, the cleaning agent can clean the paint pump 18, the spray pipe 19, and the material nozzle 21 simultaneously. The recovery pipe 25 can prevent the sprayed cleaning agent from affecting the mixture behind the vent 7, and the sprayed cleaning agent is blocked and recovered into the recovery box 9 below the connecting pipe 26 for storage. There is a solenoid valve on the top of the recovery box 9, which can close the inlet to prevent evaporation from flowing into the air duct 12 when not in use. The drive motor 20 can drive the material nozzle 21 to move back and forth for spraying by using the lead screw 23 to rotate in both directions. The slide bar 24 can stabilize the sliding of the material nozzle 21. The recovery tube 25 and the sliding baffle 27 can surround the front and sides of the material nozzle 21 to prevent the cleaning agent from being sprayed onto the mixed foam behind the vent 7. At the same time, the squeezing ramps 31 at the upper and lower ends of the material nozzle 21 can squeeze the sliding baffle 27 forward by the guide ramp 29 when the material nozzle 21 enters or exits the recovery tube 25, so that the material nozzle 21 can smoothly enter and exit the recovery tube 25. After the guide ramp 29 and the squeezing ramp 31 are separated, the sliding baffle 27 is reset by the spring 30 to achieve the blocking function. The recycling box 210 has a solenoid valve on top, which can collect the cleaning agent that falls from the bottom of the air duct 12 and seal it after the device stops working to prevent the cleaning agent from evaporating. The protective bracket 22 can prevent the mixture foam from splashing onto the lead screw 23 when it is sprayed out. Example

[0030] A computer room gas fire suppression system, such as Figures 1-9 As shown, a synchronous pulley assembly 32 is fixedly connected to one end of the fan blade 8, and a reversing motor 34 is fixedly connected to the inside of the ventilation opening 7. The power output end of the reversing motor 34 and the multiple synchronous pulley assemblies 32 are connected by a synchronous belt component 33. The timing pulley assembly 32 and timing belt component 33 can be in the form of sprocket chain drive or timing belt drive, so that multiple fan blades 8 can rotate synchronously to achieve opening and closing, while the output shaft of the flip motor 34 is equipped with parts that can match the timing belt component 33 to drive the fan blades 8.

[0031] like Figures 1-9As shown, a monitoring component 3 is fixedly connected to the top of the firewall body 1, and multiple gas fire extinguishers 6 are fixedly connected to the bottom of the firewall body 1. The monitoring component 3 contains various electronic components for fire monitoring, such as temperature monitoring components, smoke detectors, and wireless signal transmission components. When a fire is detected, the gas fire extinguishers 6 can be controlled to spray gas to extinguish the fire and the ventilation openings 7 can be sealed.

[0032] like Figures 1-9 As shown, a pressure relief valve 4 is fixedly connected to the top of the firewall body 1, and a sealing door 2 is rotatably connected to one side of the firewall body 1. The sealing door 2 is preferably a sealing door 2 with a sealing airbag installed, which can prevent gas from flowing from the door gap. The pressure relief valve 4 can prevent the firewall body 1 from being damaged by the increase in air pressure due to long-term sealing.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
