Description

Technical Field

[0001] The invention relates to the technical field of ventilation systems, and in particular to an integrated smoke prevention and ventilation device for an information room. Background Art

[0002] As the core location of various information systems, the information room carries a large number of electronic equipment. The smoke prevention and ventilation system is a key part of the information room environment control, which directly affects the normal operation of the equipment in the room and the life safety of personnel. The electronic equipment in the information room will generate a lot of heat during operation, and an effective ventilation system is required to maintain a suitable temperature and humidity environment. At the same time, once an emergency such as a fire occurs, smoke must be removed in time to prevent the spread of smoke from causing damage to equipment and personnel.

[0003] Traditional smoke control and ventilation systems are designed independently, requiring their own pipes, equipment and control lines. This results in crisscrossing pipes in the machine room, taking up a lot of valuable space.

[0004] In the current construction of information rooms, smoke control and ventilation systems are often planned and constructed uniformly based on the scale of the entire room. When a fire occurs in an electronic device in the room due to short circuit, overload, etc., the smoke and heat generated will quickly spread in the room. Since the existing smoke control and ventilation systems lack the ability to accurately control a single device or a local area, they cannot isolate the electronic equipment that has caught fire from the electronic equipment that is operating normally. Smoke will spread to every corner of the room with the ventilation airflow, which will not only corrode and damage the surrounding electronic equipment, affecting their normal operation and service life, but may also cause other equipment to malfunction due to the inhalation of harmful substances in the smoke, and even trigger a chain reaction, causing equipment damage and data loss on a larger scale.

[0005] Therefore, it is necessary to develop and apply a new integrated smoke prevention and ventilation system that can achieve local isolation and precise control. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an integrated smoke prevention and ventilation device for an information room to solve the above problems.

[0007] The present invention provides the following technical solutions: An integrated smoke prevention and ventilation device for an information room, comprising ventilation components arranged one by one just above the electronic equipment; The ventilation component comprises: An upper top plate and a lower bottom frame, wherein an airbag is connected between the upper top plate and the lower bottom frame, and when the airbag is deployed, the corresponding electronic device below is enclosed; The upper top plate is provided with an air outlet duct, a lower first tube, a lower second tube, an air inlet port and an air outlet port, and the air outlet duct is equipped with an axial flow fan; One end of the lower first tube is connected to the air inlet of the airbag, and one end of the lower second tube is connected to the air outlet of the airbag; A steering assembly, wherein the steering assembly has at least two modes; in the first mode, the air outlet duct is controlled to be connected to the air inlet port, and the lower first tube, the lower second tube and the air outlet port are closed; in the second mode, the air outlet duct is controlled to be connected to the lower first tube, the lower second tube and the air outlet port are connected, and the air inlet port is closed.

[0008] Preferably, the bottom wall of the upper top plate is provided with a groove matched with the lower bottom frame, and the airbag is folded and stored in the groove under normal conditions.

[0009] Preferably, the steering assembly comprises a valve body and a valve core sliding in the valve body, and the valve core is provided with a second channel of a U-shaped structure and a first channel of a straight-through structure; In the first mode, the air outlet duct and the air inlet port are connected through the second channel; In the second mode, the air outlet duct and the lower first tube are connected through the first channel, and the lower second tube and the air outlet port are connected through the second channel.

[0010] Preferably, a return spring is provided between the valve body and the valve core, and the return spring pushes the valve core to move toward the first mode.

[0011] Preferably, the lower first tube is connected to an external positive pressure gas source, and the lower first tube is communicated with the inner cavity of the valve body through an air supply pipe, and a one-way valve is installed on the air supply pipe.

[0012] Preferably, the inner cavity of the airbag forms a serpentine air passage extending from the air inlet to the air outlet.

[0013] Preferably, the serpentine gas passage has an adsorption component built into it.

[0014] Preferably, the adsorption component includes a memory foam body with a hollow structure and an activated carbon layer arranged on the inner side wall of the memory foam body, and the memory foam body is adapted to the serpentine air passage after being heated and unfolded.

[0015] Preferably, the adsorption component further comprises a movable ball movably placed in the inner cavity of the memory sponge.

[0016] Preferably, the activated carbon layers on the inner and outer walls of the memory foam body are provided with more than two groups, and a gap is left between two adjacent activated carbon layers; The movable sphere is internally provided with activated carbon powder, a notch is provided on the side wall of the movable sphere, and a micro-perforated film is provided at the notch.

[0017] The present invention has the following beneficial technical effects: The present invention performs positive blowing ventilation on the electronic equipment under normal conditions by cooperating with the axial flow fan and the air outlet duct; When a fire occurs in an electronic device, the external positive pressure air source controls the corresponding airbag to deploy, and the deployed airbag surrounds the local area of ​​the electronic device and isolates it from the surrounding area, preventing the fire from spreading to the surrounding normal equipment area. At the same time, the axial flow fan reverses the air suction to suck away the smoke, preventing the smoke from spreading to the surrounding normal equipment area.

[0018] Under normal circumstances, the memory foam is small in size and will not block the rapid flow of air in the serpentine air channel of the airbag, thus not hindering the rapid deployment of the airbag; after the airbag is deployed, when the heated smoke flows in the serpentine air channel, the memory foam is heated and expanded, and the expanded memory foam filters the smoke through the activated carbon layer thereon.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: An integrated smoke prevention and ventilation device for an information room, such as Figure 1-Figure 9 As shown: like Figure 1 As shown, multiple groups of independently distributed electronic devices 100 are installed on the floor of the machine room, with a certain space left between adjacent electronic devices 100, and multiple groups of mutually independent ventilation components 200 are installed on the ceiling of the machine room, and the ventilation components 200 are relatively located directly above the corresponding electronic devices 100.

[0023] like Figure 2-Figure 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 tube 4, a lower second tube 5, an air bag 6 and a steering assembly 7; The upper top plate 1 is fixed to the ceiling of the machine room, and a groove matching the shape of the lower bottom frame 2 is provided on the bottom wall of the upper top plate 1. An airbag 6 is connected between the top wall in the groove and the lower bottom frame 2. The airbag 6 can be inserted into the groove after being deflated and reduced in size, and then the upper part of the lower bottom frame 2 is embedded in the groove. An elastic layer is provided on the outer surface of the lower bottom frame 2 to ensure an interference fit with the groove.

[0024] The airbag 6 is made of fireproof material and has an air inlet 61 and an air outlet 62 .

[0025] The steering assembly 7 includes a valve body 71 and a valve core 74. The top of the valve body 71 is provided with an air inlet port 72 and an air outlet port 73. The air inlet port 72 and the air outlet port 73 are both connected to the external atmosphere. The bottom of the valve body 71 is provided with an air outlet duct 3, a lower first tube 4 and a lower second tube 5. The air outlet of the air outlet duct 3 faces the electronic device 100 below. The lower end of the lower first tube 4 is connected to the air inlet port 61 of the airbag 6, and the lower end of the lower second tube 5 is connected to the air outlet port 62 of the airbag 6. like Figure 4 As shown, the external positive pressure gas source ( Figure 4The air outlet pipe 3 is connected to the inner cavity of the valve body 71 through the air delivery pipe 32, and a one-way valve 33 is installed on the air delivery pipe 32; the air outlet pipe 3 has an axial flow fan 31 built in. The valve body 71 is linearly slidably connected with a valve core 74, and a return spring 75 is connected between the valve core 74 and the inner wall of the valve body 71. The valve core 74 is provided with a second channel 742 of a U-shaped structure and a first channel 741 of a straight-through structure.

[0026] like Figure 5 As shown, under normal conditions, the elastic force of the return spring 75 pushes the valve core 74 to move to the left and is in the first mode. At this time, the air inlet port 72 is connected to the air outlet duct 3 through the second channel 742, and the lower first tube 4, the lower second tube 5 and the air outlet port 73 are in a closed state; the axial flow fan 31 blows forward to blow the space in the atmosphere through the air inlet port 72, the second channel 742 and the air outlet duct 3 to the electronic device 100, thereby achieving a ventilation effect.

[0027] When the temperature sensor, smoke sensor, or other external monitoring device detects a fire in the electronic device 100, the corresponding solenoid valve is controlled to open, and the external positive pressure air source is delivered to the airbag 6 through the lower first tube 4 and the air inlet 61. The airbag 6 is inflated and expanded, and in the process, the lower bottom frame 2 is pushed out of the groove of the upper top plate 1. At this time, the state of the airbag 6 and the lower bottom frame 2 is as follows: Figure 3 As shown, the lower frame 2 and the airbag 6 are both in a "mouth"-shaped structure to surround the corresponding electronic device 100.

[0028] After the air pressure in the airbag 6 reaches the set value, the positive pressure air source is diverted and delivered to the inner cavity of the valve body 71 through the air supply pipe 32, and the positive pressure air source pushes the valve core 74 to move rightward to the right limit position (the second mode), and compresses the return spring 75 to generate a reverse elastic force. At this time, the one-way valve 33 on the air supply pipe 32 blocks the reverse flow of the positive pressure air source, and then controls the axial flow fan 31 to blow in the reverse direction; in the second mode, Figure 6 As shown, the air outlet duct 3 is connected to the lower first tube 4 through the second channel 742 , and the air outlet port 73 is connected to the lower second tube 5 through the first channel 741 .

[0029] In the second mode, the axial flow fan 31 blows in the opposite direction to suck the smoke and fumes generated by the fire into the air outlet duct 3, and transports them into the air bag 6 through the second channel 742, the lower first pipe 4 and the air inlet 61. Figure 3As shown, the inner cavity of the airbag 6 forms a serpentine air path through the isolation portion 63, so that the air input from the air inlet 61 flows through the serpentine air path and is discharged from the air outlet 62, and then passes through the lower second tube 5, the first channel 741 and the air outlet port 73 to be discharged to the atmosphere; in this process, the positive pressure air source maintains constant pressure blowing, and further, a one-way valve can be built into the second channel 742, so that when the axial flow fan 31 reverses the air intake, the air flow can only flow from the second channel 742 to the first tube 4.

[0030] Adsorption components 8 are evenly arranged along the trajectory of the serpentine air passage of the airbag 6. The adsorption component 8 is placed inside the airbag 6. After the smoke is generated from the electronic device 100, it is directly sucked into the airbag 6 and filtered immediately, reducing the diffusion and leakage of the smoke during the transmission process. Compared with the external adsorption component 8, the built-in filtration of the adsorption component 8 can process the smoke more timely, improve the filtration efficiency, and ensure that harmful substances and particulate matter in the smoke are removed in a short time; the airbag 6 surrounds the electronic device 100, which is itself a physical barrier that can prevent the flame from directly contacting the surrounding flammable materials and other equipment. After the built-in adsorption component 8, the internal structure of the airbag 6 is more substantial, which improves the stability of the airbag 6 after deployment; The adsorption component 8 includes a memory sponge 81, an activated carbon layer 82 and a movable ball 83. The memory sponge 81 is hollow inside and has a spherical structure. The activated carbon layer 82 is fixed to the inner wall of the memory sponge 81. One end of the memory sponge 81 is fixed to the isolation portion 63 of the airbag 6. The movable ball 83 is smaller than the spherical memory sponge 81 and is placed in the inner cavity of the memory sponge 81. The movable ball 83 can be made of rubber material and has a certain elastic force.

[0031] At the same time, the activated carbon layer 82 has a certain reflective ability to thermal radiation. When thermal radiation is projected onto the surface of the activated carbon layer 82, part of the thermal radiation will be reflected back instead of being completely absorbed or transmitted. This reflection effect can reduce the spread of thermal radiation to the surrounding environment, just like setting up a "reflective barrier" for thermal radiation.

[0032] like Figure 7 As shown in the left part, the adsorption component 8 is in a flattened state before the airbag 6 is ventilated. The adsorption component 8 in this state will not block the positive pressure air source from flowing quickly 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.

[0033] like Figure 8 As shown in the right part, in the second mode, the axial flow fan 31 sucks the heated smoke and fumes into the serpentine airflow channel of the airbag 6. When the heated smoke passes through the adsorption component 8, the memory sponge 81 is heated and returns to its original spherical structure. At this time, the memory sponge 81 is adapted to the serpentine airflow channel of the airbag 6.

[0034] The unfolded memory sponge 81 will filter and absorb the large smoke particles flowing in the serpentine airflow channel, and the activated carbon layer 82 on the inner wall of the memory sponge 81 will filter and absorb the smoke particles and harmful substances, thereby achieving the purpose of purifying smoke and smog.

[0035] Activated carbon and a filter device may be built into the air outlet port 73 to perform filtering when the memory foam body 81 is not deployed.

[0036] The smoke and fumes will drive the movable spheres 83 to move in the process of passing through the memory foam body 81. The movement of the movable spheres 83 will slightly knock on the activated carbon layer 82, which is conducive to the memory foam body 81 to return to its original state. At the same time, the knocking of the activated carbon layer 82 will accelerate the flow of smoke in the activated carbon layer 82, so that more smoke molecules can contact the surface and pores of the activated carbon faster, increasing the contact opportunity between the smoke and the activated carbon layer 82; the knocking may also cause some of the pores of the activated carbon layer 82 that were originally blocked to be exposed again, thereby increasing the effective adsorption area of ​​the activated carbon.

[0037] Further, such as Fig. 9 As shown, the inner wall of the memory sponge 81 is covered by multiple groups of activated carbon layers 82, and a gap is left between two adjacent activated carbon layers 82 to facilitate the flattening of the memory sponge 81. If the inner wall of the memory sponge 81 is only covered by a complete activated carbon layer 82, the activated carbon layer 82 has a certain strength that is not convenient for the memory sponge 81 to be flattened, and there is a situation where the activated carbon layer 82 is damaged during the flattening process; The movable sphere 83 is hollow inside and 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. The activated carbon powder inside the movable sphere 83 will not pass through the micro-perforated membrane 831 when it is stationary, but can pass through the micro-perforated membrane 831 when the movable sphere 83 is moving. The activated carbon powder can fill the gap between the two activated carbon layers 82, and a glue layer (self-adhesive) is provided on the side where the gap between the two activated carbon layers 82 is close to each other, and the activated carbon powder can be adsorbed and fixed by the glue layer to fill the gap between the two activated carbon layers 82.

[0038] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
