Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of ventilation systems, in particular to an information room smoke prevention and ventilation integrated device. BACKGROUND
[0002] As the core place of various information systems, information rooms carry a large amount of electronic equipment, and the smoke prevention and ventilation system is a key part of the environmental control of information rooms, which directly affects the normal operation of equipment and the safety of personnel in the room. Electronic equipment in the information room will generate a large amount of heat during operation, which requires an effective ventilation system to maintain a suitable temperature and humidity environment. At the same time, in case of emergency such as fire, smoke needs to be removed in time to prevent the spread of smoke from causing damage to equipment and personnel.
[0003] The traditional smoke prevention and ventilation system is designed independently, and requires its own pipeline, equipment and control circuit. This results in a large number of pipelines crisscrossing in the room, occupying a large amount of valuable space.
[0004] In the current construction of information rooms, the smoke prevention and ventilation system is often planned and constructed based on the scale of the entire room. When a fire is caused by a short circuit, overload or other reasons in an electronic device in the room, the smoke and heat generated will quickly spread in the room. Due to the lack of precise control capability for individual devices or local areas in the existing smoke prevention and ventilation system, the electronic device where the fire occurs cannot be isolated from the normally operating electronic devices in time. Smoke will spread to every corner of the room along with the ventilation airflow, not only causing corrosion and damage to the surrounding electronic equipment, affecting its normal operation and service life, but also causing other devices to malfunction due to inhaling harmful substances in the smoke, and even triggering a chain reaction, causing greater damage to equipment and data loss in a larger area.
[0005] Therefore, it is necessary to develop and apply a new smoke prevention and ventilation integrated system that can achieve local isolation and precise control. SUMMARY

[0042] 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.
[0043] Example:
[0044] An integrated smoke control and ventilation device for information computer rooms, such as Figures 1-9 As shown:
[0045] like Figure 1 As shown, multiple sets of independently distributed electronic devices 100 are installed on the floor of the computer room, with a certain space between adjacent electronic devices 100. Multiple sets of independent ventilation components 200 are installed on the ceiling of the computer room, with the ventilation components 200 located directly above the corresponding electronic devices 100.
[0046] like Figures 2-4 As shown, the ventilation assembly 200 includes an upper top plate 1, a lower bottom frame 2, an air outlet duct 3, a lower first pipe 4, a lower second pipe 5, an airbag 6, and a steering assembly 7;
[0047] The upper top plate 1 is fixed to the ceiling of the computer room. The bottom wall of the upper top plate 1 has a groove that matches the shape of the lower bottom frame 2. An airbag 6 is connected between the top wall of the groove and the lower bottom frame 2. After the airbag 6 is deflated and shrunk, it can be inserted into the groove. Then the upper part of the lower bottom frame 2 is embedded into the groove. An elastic layer is provided on the outer surface of the lower bottom frame 2 to make an interference fit with the groove.
[0048] The airbag 6 is made of fire-resistant material and has an air inlet 61 and an air outlet 62.
[0049] The steering component 7 includes a valve body 71 and a valve core 74. An air inlet port 72 and an air outlet port 73 are provided at the top of the valve body 71. Both the air inlet port 72 and the air outlet port 73 are connected to the external atmosphere. An air outlet pipe 3, a lower first pipe 4 and a lower second pipe 5 are provided at the bottom of the valve body 71. The air outlet of the air outlet pipe 3 faces the electronic device 100 below. The lower end of the lower first pipe 4 is connected to the air inlet 61 of the airbag 6, and the lower end of the lower second pipe 5 is connected to the air outlet 62 of the airbag 6;
[0050] As Figure 4 shown, the external positive pressure air source ( Figure 4 shown by the red line in
[0051] As Figure 5 shown, under normal conditions, the elastic force of the return spring 75 pushes the valve core 74 to move left to the first mode. At this time, the air inlet port 72 is connected to the air outlet pipe 3 through the second channel 742, and the lower first pipe 4, the lower second pipe 5 and the air outlet port 73 are in a closed state; The axial flow fan 31 blows forward to blow the air in the atmosphere through the air inlet port 72, the second channel 742 and the air outlet pipe 3 to the electronic device 100, achieving a ventilation effect.
[0052] When a fire occurs in the electronic device 100 is detected by external sensors such as a temperature sensor and a smoke sensor, the corresponding solenoid valve is controlled to open. The external positive pressure air source is delivered to the airbag 6 through the lower first pipe 4 and the air inlet 61. The airbag 6 is inflated and expanded to increase its volume. During this process, the lower bottom frame 2 is pushed out of the groove of the upper top plate 1. At this time, the states of the airbag 6 and the lower bottom frame 2 are as Figure 3 shown, the lower bottom frame 2 and the airbag 6 are both in a "square" shape structure to surround the corresponding electronic device 100.
[0053] After the air pressure in the airbag 6 reaches the set value, the positive pressure air source is shunted and delivered to the inner cavity of the valve body 71 through the air delivery pipe 32. The positive pressure air source pushes the valve core 74 to move right to the right limit (the second mode), and compresses the return spring 75 to generate a reverse elastic force. At this time, the check valve 33 on the air delivery pipe 32 blocks the reverse flow of the positive pressure air source. Then, the axial flow fan 31 is controlled to blow in the reverse direction; In the second mode, as Figure 6 shown, the air outlet pipe 3 is connected to the lower first pipe 4 through the second channel 742, and the air outlet port 73 is connected to the lower second pipe 5 through the first channel 741.
[0054] In the second mode, the axial flow fan 31 blows in the opposite direction, drawing the smoke and fumes generated by the fire into the outlet duct 3, and then transporting them through the second channel 742, the lower first pipe 4, and the air inlet 61 to the airbag 6. Figure 3 As shown, the inner cavity of the airbag 6 forms a serpentine air passage through the isolation part 63, so that the air input from the air inlet 61 flows through the serpentine air passage and is discharged from the air outlet 62, and then passes through the lower second pipe 5, the first channel 741 and the air outlet 73 to be discharged into the atmosphere. During this process, the positive pressure air source maintains constant pressure blowing. Furthermore, a one-way valve can be built into the second channel 742 so that when the axial flow fan 31 draws air in the opposite direction, the airflow can only flow from the second channel 742 to the first pipe 4.
[0055] The serpentine air passage of the airbag 6 is uniformly equipped with adsorption components 8 along its trajectory. By placing the adsorption components 8 inside the airbag 6, the flue gas generated from the electronic device 100 is directly drawn into the airbag 6 and immediately filtered, reducing the diffusion and leakage of the flue gas during transmission. Compared to externally placed adsorption components 8, the internal filtration of the adsorption components 8 allows for more timely treatment of the flue gas, improving filtration efficiency and ensuring the removal of harmful substances and particulate matter from the flue gas in a short time. The airbag 6, surrounding the electronic device 100, acts as a physical barrier, preventing the flame from directly contacting surrounding flammable materials and other equipment. The internal structure of the airbag 6 is more robust after deployment, improving its stability.
[0056] The adsorption component 8 includes a memory foam 81, an activated carbon layer 82, and a movable sphere 83. The memory foam 81 has a hollow interior and a spherical shape. The activated carbon layer 82 is fixed to the inner wall of the memory foam 81. One end of the memory foam 81 is fixed to the isolation part 63 of the airbag 6. The movable sphere 83 is smaller than the spherical memory foam 81 and is placed inside the memory foam 81. The movable sphere 83 can be made of rubber and has a certain degree of elasticity.
[0057] Meanwhile, the activated carbon layer 82 has a certain reflective ability for thermal radiation. When thermal radiation is projected onto the surface of the activated carbon layer 82, some of the thermal radiation will be reflected back instead of being completely absorbed or transmitted. This reflective effect can reduce the propagation of thermal radiation to the surrounding environment, just like setting up a "reflective barrier" for thermal radiation.
[0058] like Figure 7 As shown in the left part, the adsorption component 8 is in a flattened state before the airbag 6 is inflated. In this state, the adsorption component 8 will not block the positive pressure air source from flowing rapidly in the serpentine airflow channel of the airbag 6, which is conducive to the rapid deployment of the airbag 6; the temperature of the positive pressure air source is usually low.
[0059] like Figure 8As shown in the right part, in the second mode, the axial flow fan 31 draws the heated flue gas and smoke into the serpentine airflow channel of the airbag 6. When the heated flue gas passes through the adsorption component 8, the memory foam 81 is heated and restores its original shape to a spherical structure. At this time, the memory foam 81 is compatible with the serpentine airflow channel of the airbag 6.
[0060] Once unfolded, the memory foam 81 filters and adsorbs large particles of flue gas flowing through the serpentine airflow channel, while the activated carbon layer 82 on the inner wall of the memory foam 81 filters and adsorbs particulate matter and harmful substances in the flue gas. This achieves the purpose of purifying the flue gas and smoke.
[0061] Activated carbon and a filter can be built into the air outlet 73 to filter the air when the memory foam 81 is not unfolded.
[0062] As the smoke and vapor pass through the memory foam 81, they cause the movable sphere 83 to move. The movement of the movable sphere 83 slightly taps the activated carbon layer 82, which helps the memory foam 81 return to its original shape. At the same time, the tapping of the activated carbon layer 82 accelerates the flow of smoke within the activated carbon layer 82, allowing more smoke molecules to contact the surface and pores of the activated carbon more quickly, increasing the contact opportunities between the smoke and the activated carbon layer 82. The tapping may also re-expose some of the pores in the activated carbon layer 82 that were originally blocked, increasing the effective adsorption area of the activated carbon.
[0063] Furthermore, such as Figure 9 As shown, the inner wall of the memory foam 81 is covered by multiple sets of activated carbon layers 82, and there is a gap between two adjacent activated carbon layers 82 to facilitate the flattening of the memory foam 81. If the inner wall of the memory foam 81 is covered by only one complete activated carbon layer 82, the activated carbon layer 82 has a certain strength and is not easy to flatten the memory foam 81, and there is a possibility of damaging the activated carbon layer 82 during the flattening process.
[0064] The movable sphere 83 has a hollow interior and is filled with activated carbon powder. A notch is provided on the side wall of the movable sphere 83, and a micro-perforated membrane 831 is provided at the notch. When the movable sphere 83 is stationary, the activated carbon powder inside the movable sphere 83 will not pass through the micro-perforated membrane 831. When the movable sphere 83 moves, the activated carbon powder can pass through the micro-perforated membrane 831 and fill the gap between the two activated carbon layers 82. An adhesive layer (adhesive) is provided on the side of the gap between the two activated carbon layers 82 that is close to each other. The activated carbon powder can be adsorbed and fixed through the adhesive layer and fill the gap between the two activated carbon layers 82.
[0065] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
