Description

Technical Field

[0001] The invention relates to a smoke prevention system for an uninterruptible power supply room. Background Art

[0002] With the development of the IT industry in recent years, there are more and more loads such as computers and communication equipment that are sensitive to the power supply environment, and the demand and attention for power supplies with stable power quality are also increasing rapidly.

[0003] However, in general power systems, there is the possibility that power supply will be temporarily restricted due to unexpected events, and the interruption of computer and information systems caused by such events will cause huge social losses and chaos.

[0004] Therefore, it becomes more and more important to supply power through an uninterruptible power supply (UPS), which can ensure that the power supply is not affected by power abnormalities such as voltage fluctuations, frequency fluctuations, momentary power outages, and momentary power outages.

[0005] The uninterruptible power supply room is usually composed of a rectifier, an inverter and a battery. When an external commercial power supply is supplied, the rectifier converts the AC power of the external commercial power supply into DC power, part of the DC power converted by the rectifier is converted into AC power by the inverter to power the AC load, and the rest is used to charge the battery.

[0006] When the supply from the external commercial power source is interrupted (such as a power outage), the DC power in the battery is discharged from the battery and converted into AC power by the inverter, and then supplied to the AC load, so that the AC load can continue to receive power supply even if the supply from the external commercial power source is interrupted.

[0007] The battery rack 11 of the uninterruptible power supply room is composed of a plurality of battery modules, which are arranged on the rack and connected to each other.

[0008] Reference Figure 1 A ventilation facility 12 is provided on the inner ceiling of the uninterruptible power supply room 10. In the absence of a fire, the ventilation facility is used to ventilate the air in the uninterruptible power supply room.

[0009] Each of these multiple battery modules has the potential to catch fire due to increased load and performance degradation caused by repeated charge and discharge.

[0010] In the early stages of a fire, the battery module first emits smoke, then flames appear and spread into a large fire.

[0011] The smoke from the battery module must be quickly discharged to the outside to prevent the fire from spreading to the surrounding area, thereby minimizing personal injury and economic losses.

[0012] Therefore, it is very important to continuously monitor the temperature of the batteries in the uninterruptible power supply room to predict the occurrence of fire, and to quickly exhaust smoke and control the spread of fire as much as possible when a fire occurs. Various technologies in this regard are currently being studied. Summary of the invention

[0013]

Technical issues

[0014] The present invention is proposed to solve the above-mentioned problems, and its purpose is to provide a smoke prevention system for an uninterruptible power supply room. When a fire occurs in one of the multiple uninterruptible power supply devices arranged inside the uninterruptible power supply room, the smoke of the uninterruptible power supply device is discharged centrally and quickly, so that the fire can be quickly extinguished while preventing personal injury.

[0015] The technical problems of the present invention are not limited to the above-mentioned technical problems, and those skilled in the art should be able to clearly understand other technical problems not mentioned based on the following description.

[0016]

Technical solution

[0017] In order to solve the above technical problems, the present invention provides a smoke prevention system for an uninterruptible power supply room, comprising: battery racks, which are arranged at certain intervals inside the uninterruptible power supply room; a main air duct, which is arranged on the upper part of each of the battery racks and discharges the smoke ejected from the battery racks to the outside in case of fire; an independent air flow regulator, which is arranged on the main air duct at certain intervals in order to be located on the upper part of the battery rack and opens and closes the main air duct separately; a main air intake fan, which is arranged on the main air duct to provide suction to the main air duct; an auxiliary air duct, which forms a branch from the main air duct and discharges the smoke sucked from the main air duct to the outside when the main air intake fan fails; and an auxiliary air intake fan, which is arranged on the auxiliary air duct to provide suction to the auxiliary air duct.

[0018] The uninterruptible power supply room uses a smoke sensing sensor to sense the extent of smoke generation, and the main air intake fan sets the suction volume according to the opening degree and number of independent air flow regulators.

[0019] The smoke sensing sensor and temperature sensing sensor arranged on the battery rack sense the interior of the uninterruptible power supply room in real time. When a fire occurs, the independent air flow regulator corresponding to the battery rack where the fire occurs is opened, and the independent air flow regulators corresponding to the battery racks in the front, rear, left and right directions of the battery rack where the fire occurs are further opened to discharge the smoke together.

[0020] When a fire occurs, the fireproof cloth installed on the top of the battery rack descends to seal the front and rear of the battery rack to prevent the fire from spreading. When the fireproof cloth descends, the impact absorption part installed at the lower end of the fireproof cloth absorbs the reaction force caused by the descending of the fireproof cloth to prevent the formation of a gap at the lower end of the fireproof cloth.

[0021] It includes a secondary airflow regulator, which is arranged between the branch point of the secondary air duct and the secondary air intake fan, and is used to open and close the secondary air duct. When the main air intake fan works normally, the secondary airflow regulator is closed. When the main air intake fan fails, the secondary airflow regulator is opened and the smoke is discharged to the outside based on the drive of the secondary air intake fan.

[0022]

Beneficial Effects

[0023] According to the present invention, when a fire occurs in one of the multiple uninterruptible power supply devices arranged inside the uninterruptible power supply room, smoke from the uninterruptible power supply device can be discharged centrally and quickly, thereby quickly extinguishing the fire and preventing personal injury.

It should also be understood that the position or arrangement of individual elements in the disclosed embodiments can be changed without exceeding the spirit and scope of the present invention. Therefore, the following detailed description is not intended to limit the present invention, and the scope of the present invention, if recorded reasonably, is only limited by the scope of the equivalents required by the attached claims and all claims. In the accompanying drawings, similar figure marks refer to features that are the same or similar in all aspects.

[0042] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0043] The existing uninterruptible power supply (UPS) room is provided with ventilation equipment on the ceiling. In normal times when there is no fire, ventilation is performed through the ventilation equipment. If a fire occurs, the ventilation equipment is turned off to seal the inside of the uninterruptible power supply (UPS) room.

[0044] In the present invention, in a state where ventilation equipment is arranged inside the uninterruptible power supply room, a smoke prevention system is further arranged in order to quickly discharge smoke emitted from the battery module in case of fire, so that the smoke can be quickly discharged to the outside.

[0045] first, Figure 2 is a plan view of a smoke prevention system for an uninterruptible power supply room according to an embodiment of the present invention, Figure 3 It is a front structural diagram of a smoke prevention system for an uninterruptible power supply room according to an embodiment of the present invention.

[0046] The smoke prevention system of the uninterruptible power supply room according to an embodiment of the present invention includes a battery rack 100 , a main air duct 200 , an independent air flow regulator 300 , a main air intake fan 400 , a secondary air duct 500 , and a secondary air intake fan 700 .

[0047] The battery racks 100 can be arranged at certain intervals in a space of an uninterruptible power supply room (UPS), and the battery racks 100 can be uninterruptible power supply devices.

[0048] The battery rack 100 is generally in the shape of a rectangular parallelepiped, with the front and rear being open and the two side surfaces being closed by vertical plates.

[0049] The battery rack 100 has shelves arranged at intervals of a certain height inside, and battery modules are placed and fixed on the shelves.

[0050] Such battery racks 100 may be continuously arranged at a certain distance in the front-rear direction.

[0051] Each battery rack 100 may also be provided with a smoke sensing sensor 110 .

[0052] The smoke sensing sensor 110 senses the amount of smoke generated inside the uninterruptible power supply room 10 , and the sensed amount of smoke can be transmitted to the control unit 900 .

[0053] Each battery rack 100 may also be provided with a temperature sensing sensor 120 .

[0054] The temperature sensing sensor 120 senses the temperature generated inside the uninterruptible power supply room 10 , and the sensed temperature may be transmitted to the control unit 900 .

[0055] A fireproof cloth 130 is disposed on the upper portion of the battery rack 100 . When a fire occurs, the fireproof cloth 130 descends to the lower portion of the battery rack 100 to prevent oxygen from flowing in.

[0056] A driving motor 140 for rolling up the fireproof cloth 130 is provided on the upper part of the battery rack 100. The driving motor 140 is driven by a 24V DC power supply and winds the fireproof cloth 130 on a rotating shaft. After the fireproof cloth 130 is wound, a 12V DC power supply is maintained.

[0057] The rotating shaft may also be provided with a clutch, which is used to fix the rotating shaft with the fireproof cloth 130 wound on it so that it does not rotate when no fire is sensed. If a fire is sensed, the power supply is terminated and the fixing force used to fix the rotating shaft is released, thereby satisfying the conditions for rotating the rotating shaft.

[0058] The fireproof cloth 130 may include a shock absorbing portion 150 at a lower end portion thereof.

[0059] Reference Figure 4 The impact absorbing part 150 may include a shell 151 , a reaction force absorbing component 152 , and a buffer component 153 .

[0060] The outer shell 151 is fixed to the lower end of the fireproof cloth 130 at a certain interval, and a space portion may be formed inside.

[0061] The reaction force absorbing member 152 is formed with a certain diameter, and a plurality of spaces can be provided inside the housing 151. Thus, when a fire occurs, the fireproof cloth 130 descends and generates a reaction force, and the reaction force absorbing member 152 absorbs the reaction force while moving upward in the space.

[0062] Therefore, even if the fireproof cloth 130 drops rapidly under the action of its own weight, the reaction force absorbing component 152 can offset this effect, so that even after the fireproof cloth 130 drops, the gap can be minimized, thereby effectively preventing the oxygen supply.

[0063] The buffer component 153 is formed at the lower portion of the housing 151 and can be made of rubber or liquid silicone rubber (LSR) material.

[0064] The buffer component 153 may be closely attached to the inner bottom surface of the water tank 160 , or may be closely attached to the floor surface of the uninterruptible power supply room 10 .

[0065] The buffer component 153 absorbs the impact for the first time when the fireproof cloth 130 descends, and then the reaction force absorbing component 152 absorbs the impact for the second time, thereby preventing the fireproof cloth 130 from bouncing upward due to the reaction force.

[0066] A water tank 160 is disposed at the lower portion of the battery rack 100 , and a fire extinguishing liquid spraying portion 170 for spraying fire extinguishing liquid is disposed at the upper central portion of the battery rack 100 through a pipe introduced from the outside.

[0067] The pipe of the fire extinguishing liquid spraying unit 170 has nozzles, each of which is located at the upper portion of the battery rack 100 .

[0068] Thus, when a fire occurs, the fire extinguishing liquid can be sprayed through the nozzle of the fire extinguishing liquid spraying unit 170 when the fireproof cloth 130 is lowered, and the sprayed fire extinguishing liquid is stored in the water tank 160. One side of the water tank may have a drain pipe portion, and the fire extinguishing liquid stored in the water tank can be discharged as needed.

[0069] The main air duct 200 is arranged on the upper part of the battery rack 100 inside the uninterruptible power supply room 10 and can be connected to the outside of the building.

[0070] The main air duct 200 is a passage for discharging smoke generated when a fire occurs to the outside. The main air duct 200 may have different inner diameters according to the number of battery modules arranged.

[0071] The independent air flow regulator 300 can be disposed on the main air duct 200 and disposed facing the upper part of the battery rack 100 at a certain interval.

[0072] That is, the independent air flow regulator 300 may be disposed on the upper portion of each battery rack 100 to rapidly discharge smoke.

[0073] The independent air flow regulator 300 may be opened and closed by a motor drive, and the independent air flow regulator 300 may be connected to the control part 900 and operated by the control of the control part 900 .

[0074] The independent damper 300 is closed during normal operation and is opened in the event of a fire.

[0075] In this case, the independent air flow regulator 300 disposed on the upper portion of the battery rack 100 where no fire occurs will remain in a closed state.

[0076] That is, the smoke sensing sensor 110 and the temperature sensing sensor 120 disposed on the top of the battery rack 100 are always powered on to sense the internal conditions of the uninterruptible power supply room 10 .

[0077] When smoke is sensed by the smoke sensing sensor 110 and the temperature sensing sensor 120, the control unit 900 may open the independent airflow regulator 300 of the uninterruptible power supply device and close the independent airflow regulators 300 around the uninterruptible power supply device to discharge smoke in a centralized manner.

[0078] When a fire is sensed by the smoke sensing sensor 110 and the temperature sensing sensor 120, the control unit 900 opens the independent airflow regulator 300 of the uninterruptible power supply device, opens the independent airflow regulators 300 corresponding to the uninterruptible power supply devices in the left and right, front and back directions of the uninterruptible power supply device, and closes the independent airflow regulators 300 of the uninterruptible power supply devices where no fire has occurred.

[0079] As described above, when a fire occurs, the main intake fan 400 or the auxiliary intake fan 700 may be controlled by the control unit 900 to adjust the rotation speed to adjust the suction volume, and the control unit 900 sends notification information to the management office and the competent fire department.

[0080] That is, in the present invention, when a fire occurs in an uninterruptible power supply device, a total of five independent airflow regulators 300, including an independent airflow regulator 300 corresponding to the uninterruptible power supply device where the fire occurs and independent airflow regulators 300 corresponding to a total of four uninterruptible power supply devices in front, behind, left and right, will be opened and smoke will be discharged in a concentrated manner to effectively prevent the spread of fire and achieve rapid fire response.

[0081] In the present invention, when smoke is sensed, the fireproof cloth 130 may not be lowered, but when a fire occurs, the fireproof cloth 130 is lowered to block the inflow of oxygen and the independent airflow regulator 300 of the uninterruptible power supply where the fire occurs is opened to discharge the smoke.

[0082] The main air intake fan 400 may be disposed behind the independent air flow regulator 300 .

[0083] The main air intake fan 400 provides suction to the passage inside the main air duct 200 so as to quickly discharge smoke in the battery module to the outside when a fire occurs.

[0084] The independent air flow regulator 300 and the main air intake fan 400 are connected to the control unit 900 and are operated under the control of the control unit 900 .

[0085] The main air intake fan 400 starts to operate according to the opening signal of the independent air flow regulator 300. When the independent air flow regulator 300 is opened, the main air intake fan 400 can discharge smoke.

[0086] That is, all the smoke sensing sensors 110 arranged on the battery racks 100 inside the uninterruptible power supply room 10 sense smoke.

[0087] After receiving the sensed signal, the control unit 900 sets the opening of the independent air flow regulator 300 , detects the number of independent air flow regulators 300 corresponding to the battery rack 100 where the fire occurs, and sets the suction force of the main intake fan 400 .

[0088] Therefore, the present invention can quickly respond to the fire by intensively sucking the smoke emitted from the battery rack 100 where the fire occurs and discharging it to the outside.

[0089] In addition, when the smoke cannot be discharged to the outside through the main air duct 200, the auxiliary air duct 500 is configured to discharge the smoke in the main air duct 200 to the outside.

[0090] The auxiliary air duct 500 is branched from the main air duct 200 and extends outward.

[0091] When the main intake fan 400 fails, the secondary air duct 500 may discharge smoke to the outside.

[0092] The secondary air intake fan 700 is configured to suck and discharge the smoke discharged through the main air duct 200 disposed on the secondary air duct 500 toward one side of the secondary air duct 500 .

[0093] The secondary air intake fan 700 may be disposed on the secondary air duct 500 behind the secondary air flow regulator 600 .

[0094] The auxiliary air intake fan 700 is connected to the control unit 900 and is operated under the control of the control unit 900 .

[0095] When the main air intake fan 400 fails, the control unit 900 drives the auxiliary air intake fan 700 to redirect the smoke discharged through the main air duct 200 to the auxiliary air duct 500. In this way, even if the smoke cannot be discharged from the main air duct 200 due to a failure, the delayed discharge of the smoke can be prevented, the smoke will not flow back to the uninterruptible power supply room 10, and the smoke can be quickly discharged from the auxiliary air duct 500.

[0096] In addition, a secondary air flow regulator 600 may be further included between the branch point between the main air duct 200 and the secondary air duct 500 and the secondary air intake fan 700 .

[0097] When smoke is discharged from the main air duct 200 side, the secondary air flow regulator 600 can prevent the smoke from flowing back from the secondary air duct 500 side.

[0098] The secondary air flow regulator 600 is connected to the control unit 900 and operates under the control of the control unit 900. Therefore, when the main air intake fan 400 fails, the secondary air flow regulator 600 can be opened to change the channel, and the secondary air intake fan 700 can be started to discharge smoke to the outside through the secondary air duct 700.

[0099] In addition, refer to Figure 6 The smoke prevention system for an uninterruptible power supply room according to another embodiment of the present invention may further include an air supply unit 800, which can provide external air to the internal space of the uninterruptible power supply room after the fire is extinguished.

[0100] The air supply unit 800 may include an air supply pipe 810 , a filter unit 820 , and an air suction pump 830 .

[0101] The air supply pipe 810 may be arranged to connect the inner space of the uninterruptible power supply room with the outside.

[0102] The end of the air supply pipe 810 does not need to extend a certain length into the uninterruptible power supply room, and only needs to meet the condition of being connected to the inside of the uninterruptible power supply room.

[0103] The filter unit 820 may be disposed on the air supply pipe 810 .

[0104] The filter unit 820 filters impurities contained in the external air flowing in through the air supply pipe 810 and supplies only clean air to the inside of the uninterruptible power supply room.

[0105] The air suction pump 830 sucks in external air and provides it to the inside of the uninterruptible power supply room through the air supply pipe 810.

[0106] The air suction pump 830 is connected to the control unit 900 , and the air suction pump 830 can be operated under the control of the control unit 900 .

[0107] The suction pump 830 can change the rotation speed according to the amount of smoke discharged from the inside of the uninterruptible power supply room, thereby changing the supply amount of external air.

[0108] The air supply pipe 810 may include a temperature adjustment part 840 for adjusting the temperature of external air.

[0109] The temperature adjustment unit 840 may include a heating unit 841 and a cooling unit 842 .

[0110] The heating unit 841 is used to heat the external cold air to normal temperature, and the cooling unit 842 is used to cool the external hot air. Thus, the temperature of the external air can be adjusted to a preset temperature and provided to the inside of the uninterruptible power supply room 10.

[0111] An external temperature sensor 843 is disposed outside the uninterruptible power supply room 10 .

[0112] The temperature sensing sensor 120 and the external temperature sensor 843 are used to sense the temperature inside the uninterruptible power supply room 10 and outside the building. The control unit 900 determines whether the external air needs to be heated or cooled based on the sensed temperature and operates the temperature adjustment unit 840.

[0113] That is, if it is summer, the sensed temperature of the outside air is higher than 30 degrees, and the control unit 900 receives the temperatures sensed by the temperature sensing sensor 120 and the external temperature sensor 843 respectively, and detects the temperature difference. According to the temperature difference between the temperature inside the uninterruptible power supply room 10 and the temperature of the outside air, the control unit 900 controls the cooling unit 842, and the cooling unit 842 cools the air at normal temperature and provides air with suitable temperature to the inside of the uninterruptible power supply room 10.

[0114] In addition, if it is winter, the temperature of the sensed external air is lower than 0 degrees, and the control component 900 receives the temperatures sensed by the temperature sensing sensor 120 and the external temperature sensor 843, respectively, and detects the temperature difference. According to the temperature difference between the internal temperature of the uninterruptible power supply room 10 and the external air temperature, the control component 900 controls the heating component 841, and the heating component 841 heats the low-temperature air to provide air with a suitable temperature to the inside of the uninterruptible power supply room 10. In this way, the air in the uninterruptible power supply room 10 can quickly return to normal, which is also helpful for subsequent work after the fire is extinguished.

[0115] The preferred embodiments of the present invention are illustrated and described above, but the present invention is not limited to the specific embodiments described above. Ordinary technicians in the technical field to which the present invention belongs can make various modifications without departing from the spirit of the present invention as claimed in the claims, and these modifications should not be understood as departing from the technical ideas or viewpoints of the present invention.
