Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to a data center fire protection system. Background Technology

[0002] With the rapid development of modern communication technology, the communication industry has become a significant symbol of modern social progress. Large data centers, serving as central hubs for communication, are global collaborative networks of specific equipment used to transmit, accelerate, display, compute, and store data information on the internet infrastructure. Most electronic components in data centers are driven by low-DC power supplies. Due to the large number of electrical appliances inside, data centers require enhanced fire safety measures. For example, a data center fire protection system based on the Internet of Things (IoT), as disclosed in publication number "CN218458513U," remotely controls motors and pumps to operate when a fire occurs. The motors drive sprinkler heads out of a circular groove, and the pumps draw water from a storage tank and spray it onto the vicinity of the fire extinguishing unit through the sprinkler heads for fire suppression. By incorporating a drive mechanism, the sprinkler heads can be housed inside the fire extinguishing unit, protecting them from damage. However, this IoT-based data center fire protection system still has the following drawbacks in practical use:

[0003] When the above-mentioned institutions are in use, they spray water to the vicinity of the fire box through the sprinkler head to carry out fire extinguishing work. However, using water to extinguish fire can easily wet the server, which can easily cause the server to short-circuit and burn out, resulting in data loss and causing significant losses. At the same time, it can easily cause high-voltage current to be conducted along the water column to the fire-fighting equipment, causing electric shock injuries and deaths to personnel.

[0004] For example, a modular data center fire protection system with publication number "CN110279962A" transmits signals detected by detectors to a fire controller when a fire occurs. The fire controller then controls the fire suppression pipelines to extinguish the fire. These pipelines, in conjunction with multiple rows of server racks, meet the fire suppression pressure of a large data center. Air conditioning indoor units are connected to outdoor units via pipes. The cold air blown out by the indoor units enters the cold aisle. The cold air in the cold aisle is then drawn into the server racks for heat exchange, becoming hot air that accumulates in the hot aisle. The hot air in the hot aisle is then processed by the indoor units and sent back into the cold aisle, creating a cycle. Aisle partitions, along with the data center ceiling, isolate the hot and cold aisles. A flip-up skylight, aisle partitions, and server racks on both sides of the cold aisle form a cold aisle, ensuring that cold air can only flow through the server racks to the hot aisle. The flip-up skylights can be closed when the external ambient temperature is low, allowing external cold air to flow in. By installing exhaust fans in the hot aisle for cold air circulation and heat exchange, energy can be saved. However, this modular data center fire protection system still has the following drawbacks in actual use:

[0005] The aforementioned institutions used fire extinguishing pipes for fire suppression, but lacked the function of expelling smoke and harmful gases from the data center. As a result, after a fire broke out, the data center was filled with smoke and harmful gases, causing staff to become hypoxic and unconscious after inhaling them. At the same time, the institutions were unable to promptly alert staff after a fire broke out.

[0006] Therefore, we propose a data center fire protection system to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a data center fire protection system to address the problems mentioned in the background art. Existing data center fire protection systems on the market, when used with water for fire extinguishing, easily wet the servers, causing short circuits and data loss, resulting in significant losses. Furthermore, they can easily cause high-voltage current to be conducted along the water jet to the fire extinguishers, leading to electric shock injuries. Additionally, they lack the function of expelling smoke and harmful gases from the data center, resulting in the data center being filled with smoke and harmful gases after a fire, causing staff to inhale the smoke and become unconscious due to oxygen deprivation. Moreover, they cannot promptly alert staff after a fire occurs.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a data center fire protection system equipment, including a computer room and servers, wherein multiple servers are installed inside the computer room, and smoke detectors and heat detectors are fixedly installed on both sides of the top of the inner wall of the computer room, and alarms are fixedly connected to both sides of the top of the computer room, and a motor is installed on the left side of the top of the computer room.

[0009] It also includes: exhaust pipes are fixedly installed above the left and right sides inside the computer room, and transmission rods are rotatably connected inside the two exhaust pipes. A fan is installed at one end of each of the two transmission rods. A box is fixedly connected to the top of the computer room wall, and a pipe is fixed to the bottom of the box.

[0010] The bottom of the pipe is equipped with nozzles at equal intervals, and the pipe is connected to the inside of the box. A solenoid valve is installed inside the connection between the pipe and the box. A feeding hopper is fixed at equal intervals on the top of the box.

[0011] The top of the inner wall of the machine room is rotatably connected to the left and right sides, and the top of the first threaded rod on the left side is fixedly connected to the output end of the motor. The bottom of both first threaded rods extends into the interior of the exhaust pipe, and the outer sides of the upper ends of the two first threaded rods are connected by a pulley assembly.

[0012] Preferably, a first sleeve block is threadedly connected to the outer side of the first threaded rod, and the left side of the first sleeve block is slidably engaged with the inner wall of the machine room.

[0013] By adopting the above technical solution, the first set of blocks can be raised and lowered on the first threaded rod.

[0014] Preferably, movable rods are hinged to both sides of the housing, and a movable contact switch is fixedly connected to one end of each movable rod. Magnets are fixed to the other end of the movable rod and the right side of the first block. A spiral spring is installed at the connection position between the shaft end in the middle of the movable rod and the housing.

[0015] By adopting the above technical solution, the stored force of the spiral spring can drive the movable rod to reset.

[0016] Preferably, the two magnets are positioned opposite each other, and the magnetic properties of the opposite surfaces of the two magnets are the same. Fixed contact switches are installed on the upper part of the left and right sides of the inner wall of the computer room, and the fixed contact switches are positioned opposite to the movable contact switches.

[0017] By adopting the above technical solution, the active contact switch and the fixed contact switch come into contact, which can activate the alarm.

[0018] Preferably, the top of the inner wall of the box is symmetrically fixed with partitions, and the bottom of each partition is rotatably connected to a movable plate via a shaft. The outer side of the movable plate is in a sealed sliding connection with the inner wall of the box, and the shaft ends of the two movable plates are connected to the inner wall of the box via torsion springs.

[0019] By adopting the above technical solution, the torsion spring can be used to drive the movable plate to reset.

[0020] Preferably, a second threaded rod is rotatably connected to both sides of the bottom of the inner wall of the box, and a second sleeve block is threadedly connected to the outer side of the upper end of each of the two second threaded rods. The two sides of the second sleeve block are fixedly connected to the bottom of the movable plate by a pull rope.

[0021] By adopting the above technical solution, the second block descends and the movable plate is rotated downwards by pulling the rope.

[0022] Preferably, a stirring rod is rotatably connected between two second threaded rods inside the housing, and guide grooves are provided on the outer sides of the lower ends of the stirring rod and the two second threaded rods. A movable sleeve is slidably connected to the outer sides of the stirring rod and the two second threaded rods, and a ball is embedded in the inner wall of the movable sleeve, and the ball rolls along the guide groove.

[0023] By adopting the above technical solution, the stirring rod rotates to mix nitrogen, argon and carbon dioxide together.

[0024] Preferably, limit frames are fixed on both sides of the top of the pipe, and airbags are provided on the inner walls of the limit frames. Linkage blocks are symmetrically slidably connected through the bottom of the inner wall of the box, and the linkage blocks are I-shaped. Both ends of the linkage blocks are fixedly connected to the sides of the movable sleeve, and the bottom of the linkage blocks is in contact with the surface of the airbags.

[0025] By adopting the above technical solution, the thrust generated by the thermal expansion of the airbag can be used to push the linkage block upward.

[0026] Preferably, the end of the transmission rod away from the fan is connected to the bottom of the first threaded rod via a bevel gear set, and the transmission rod and the first threaded rod are arranged perpendicular to each other.

[0027] By adopting the above technical solution, the first threaded rod is driven to rotate by a bevel gear set.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the data center fire protection system equipment uses inert gas fire extinguishing agent to spray onto the server, thereby reducing the oxygen concentration in the computer room, preventing the fire from spreading, and achieving the effect of extinguishing the fire. It effectively avoids data loss caused by fire inside the server. At the same time, it can exhaust smoke and harmful gases in the computer room, keep the air fresh, thereby reducing the damage of fire to the server. In addition, the alarm can sound and promptly remind staff, improving safety.

[0029] 1. Equipped with a movable plate, when the server catches fire, the temperature inside the server room will rise. At this time, the airbag will expand due to the heat and push the linkage block to move upward, which will cause the second threaded rod to rotate. The movable plate will be pulled by the pull rope. At this time, the nitrogen, argon and carbon dioxide inside the box will mix together and produce an inert extinguishing agent. The inert extinguishing agent will then be sprayed onto the server through the nozzle, thereby reducing the oxygen concentration in the server room, preventing the fire from spreading, and achieving the effect of extinguishing the fire. This effectively avoids data loss caused by fire inside the server.

[0030] 2. A transmission rod is installed. The smoke detector monitors the smoke concentration inside the computer room and transmits the signal to the processor. Then, the motor drives the first threaded rod to rotate, while the fan rotates to expel the smoke and harmful gases from the computer room, keeping the air fresh and thus reducing the damage of fire to the server.

[0031] 3. Equipped with a movable contact switch, the first threaded rod drives the sleeve block to move downwards, and using the principle of like poles repelling each other, the movable rod rotates, causing the movable contact switch to come into contact with the fixed contact switch. At this time, the alarm will sound and can promptly remind the staff, improving safety. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-8 The present invention provides a technical solution: a data center fire protection system equipment, including a computer room 1 and servers 2, multiple servers 2 are installed inside the computer room 1, and smoke detectors 3 and heat detectors 30 are fixedly installed on both sides of the top of the inner wall of the computer room 1, and alarms 4 are fixedly connected to both sides of the top of the computer room 1, and a motor is installed on the left side of the top of the computer room 1.

[0043] It also includes: exhaust pipes 7 are fixedly installed through the upper left and right sides of the machine room 1, and transmission rods 8 are rotatably connected inside the two exhaust pipes 7. A fan is installed at one end of each of the two transmission rods 8. The end of the transmission rod 8 away from the fan is connected to the bottom of the first threaded rod 11 through a bevel gear set. The transmission rod 8 and the first threaded rod 11 are set perpendicular to each other. A box 5 is fixedly connected to the top of the inner wall of the machine room 1, and a pipe 10 is fixed to the bottom of the box 5. Nozzles are installed at equal intervals at the bottom of the pipe 10, and the pipe 10 is connected to the inside of the box 5. A solenoid valve 9 is installed inside the connection position between the pipe 10 and the box 5. A feeding hopper 6 is fixedly opened at equal intervals on the top of the box 5. The first threaded rod 11 is rotatably connected through the left and right sides of the top of the inner wall of the machine room 1, and the top of the left first threaded rod 11 is fixedly connected to the output end of the motor. The bottom of the two first threaded rods 11 extends into the interior of the exhaust pipe 7, and the outer sides of the upper ends of the two first threaded rods 11 are connected through a pulley assembly.

[0044] like Figure 1 and Figure 7 As shown, when a fire occurs inside server 2, the heat detector 30 and the smoke detector 3 will detect the heat and smoke in the fire, and then start the motor, causing the motor to drive the first threaded rod 11 to rotate. At the same time, the pulley assembly drives the other first threaded rod 11 to rotate synchronously. Then, the first threaded rod 11 drives the transmission rod 8 to rotate through the bevel gear set, causing the fan to rotate and exhaust the smoke and harmful gases in the computer room 1, keeping the air fresh and thus reducing the damage of the fire to server 2.

[0045] The outer side of the first threaded rod 11 is threadedly connected to the first sleeve block 12, and the left side of the first sleeve block 12 is slidably engaged with the inner wall of the machine room 1. Both sides of the housing 5 are hinged with movable rods 14, and one end of the movable rod 14 is fixedly connected to a movable contact switch 15. The other end of the movable rod 14 and the right side of the first sleeve block 12 are both fixed with magnets 16. A spiral spring 28 is installed at the connection position between the shaft end of the movable rod 14 and the housing 5. The positions of the two magnets 16 are corresponding, and the magnetic properties of the opposite faces of the two magnets 16 are the same. Fixed contact switches 13 are installed on the upper left and right sides of the inner wall of the machine room 1, and the positions of the fixed contact switches 13 and the movable contact switches 15 are corresponding.

[0046] like Figure 1 and Figure 7As shown, when the motor drives the first threaded rod 11 to rotate, the first threaded rod 11 drives the first sleeve block 12 to move downward and to the end of the movable rod 14. At this time, due to the principle of like poles repelling each other, the movable rod 14 rotates and drives the movable contact switch 15 to contact the fixed contact switch 13, thereby activating the alarm 4, which can promptly alert the staff and improve safety. After the fire is extinguished, the motor drives the first threaded rod 11 to rotate forward, causing the first sleeve block 12 to move upward and away from the end of the movable rod 14. Then, the stored force of the spiral spring 28 drives the movable rod 14 to reset, causing the movable contact switch 15 to separate from the fixed contact switch 13, thereby turning off the alarm 4.

[0047] Symmetrical partitions 31 are fixed to the top of the inner wall of the box 5, and movable plates 17 are rotatably connected to the bottom of the partitions 31 via shafts. The outer side of the movable plates 17 is in a sealed sliding connection with the inner wall of the box 5. The shaft ends of the two movable plates 17 are connected to the inner wall of the box 5 via torsion springs 19. Second threaded rods 20 are rotatably connected to both sides of the bottom of the inner wall of the box 5, and second sleeve blocks 29 are threadedly connected to the outer side of the upper end of the two second threaded rods 20. The two sides of the second sleeve blocks 29 are fixedly connected to the bottom of the movable plates 17 via pull ropes 21. A stirring rod 18 is rotatably connected inside the box 5 between the two second threaded rods 20. Furthermore, guide grooves 23 are provided on the outer sides of the lower ends of the stirring rod 18 and the two second threaded rods 20. A movable sleeve 24 is slidably connected to the outer sides of the stirring rod 18 and the two second threaded rods 20. A ball bearing 26 is embedded in the inner wall of the movable sleeve 24. The ball bearing 26 rolls along the guide groove 23. Limit frames 22 are fixed on both sides of the top of the pipe 10. An air bladder 27 is provided on the inner wall of the limit frame 22. A linkage block 25 is symmetrically slidably connected through the bottom of the inner wall of the box 5. The linkage block 25 is I-shaped. Both ends of the linkage block 25 are fixedly connected to the side of the movable sleeve 24. The bottom of the linkage block 25 is in contact with the surface of the air bladder 27.

[0048] like Figures 1-6 and Figure 8As shown, when a fire breaks out inside server 2, the temperature inside server room 1 rises sharply, causing airbag 27 to expand and push linkage block 25 upward. At this time, ball bearing 26 slides along guide groove 23, thereby driving moving sleeve 24 to automatically rotate second threaded rod 20 and stirring rod 18. Simultaneously, second threaded rod 20 drives second sleeve block 29 downward and pulls movable plate 17 downward using pull rope 21. At the same time, stirring rod 18 rotates to stir nitrogen, argon and carbon dioxide, thereby promoting their reaction. Then, the solenoid valve 9 is activated, allowing the inert extinguishing agent inside the enclosure 5 to enter the pipe 10 and be sprayed onto the server 2 through the nozzle. This reduces the oxygen concentration in the server room 1, prevents the fire from spreading, and effectively extinguishes the fire, thus preventing data loss due to a fire inside the server 2. The second threaded rod 20 is then manually rotated to move the second sleeve block 29 upward. Then, the torsion spring 19 is used to reset the movable plate 17. Finally, nitrogen, argon, and carbon dioxide are added to the enclosure 5 through the feeding hopper 6.

[0049] The working principle of this embodiment: When using this data center fire protection system equipment, combined with... Figures 1-8 As shown, when a fire occurs inside server 2, the temperature inside server room 1 rises sharply, causing the airbag 27 to expand due to the heat. This drives the movable sleeve 24 to rotate the second threaded rod 20 and the stirring rod 18 automatically. The pull rope 21 pulls the movable plate 17 downwards. At the same time, the stirring rod 18 rotates to stir the nitrogen, argon, and carbon dioxide, thereby promoting their reaction. Then, the inert extinguishing agent is sprayed onto server 2 through the nozzle, thereby reducing the oxygen concentration in server room 1, preventing the fire from spreading, and achieving the effect of extinguishing the fire. This effectively prevents data loss caused by a fire inside server 2. Next, the motor drives the first threaded rod 11 to rotate, causing the fan to rotate and expel smoke and harmful gases from server room 1, keeping the air fresh and reducing the damage of the fire to server 2. At the same time, the movable contact switch 15 contacts the fixed contact switch 13, thereby activating the alarm 4, which sounds an alarm and can promptly remind staff, improving safety and completing a series of operations.
