Description

Battery Rack Fire Suppression System for UPS

[0001] The present invention relates to a fire suppression system for a battery rack of an uninterruptible power supply.

[0002] Due to the recent development of the IT industry, loads sensitive to power conditions, such as computers and communication equipment, are increasing, and accordingly, demand for and interest in power sources with stable electricity quality are rapidly increasing.

[0003] However, in general power systems, there is a possibility that unexpected accidents may temporarily limit power supply, and the interruption of computer and information systems due to such power system accidents can cause enormous social loss and confusion.

[0004] Accordingly, the importance of power supply through an uninterruptible power supply (UPS) is increasing to prevent power abnormalities such as voltage fluctuations, frequency fluctuations, momentary power outages, and transient power outages and to provide stable power at all times.

[0005] A typical UPS consists of a rectifier, an inverter, and a battery. When supplied with an external commercial power source, the rectifier converts AC power from the external commercial power source into DC power. Some of the DC power converted by the rectifier is then converted into AC power by the inverter and supplied to the AC load, while the remainder charges the battery.

[0006] When the supply of external commercial power is interrupted, such as during a power outage, the DC power charged in the battery is discharged from the battery, converted into AC power by the inverter, and then supplied to the AC load, thereby ensuring that power is continuously supplied to the AC load even when the supply of power from the external commercial power source is interrupted.

[0007] The batteries of the uninterruptible power supply are used by placing multiple batteries on a shelf and connecting them to each other.

[0008] Each of these multiple batteries has a risk of fire due to deterioration caused by increased load and repeated continuous charging and discharging, and if a fire occurs in one of the multiple batteries, the fire may spread to adjacent batteries, potentially causing a major accident.

[0009] As such, fires in UPSs can cause significant casualties and economic damage, so prevention is paramount.

[0010] Therefore, continuously monitoring the temperature of the battery of an uninterruptible power supply to predict fire is a very important issue, and various technologies related to this are being studied.

[0011] The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide a battery rack fire suppression system of an uninterruptible power supply that, when fire or smoke is detected through a detection unit, cuts off power, lowers a flame retardant blanket, and sprays fire extinguishing liquid onto a battery module through a fire extinguishing nozzle to quickly extinguish a fire.

[0012] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0045] The following detailed description of the present invention refers to the accompanying drawings, which illustrate specific embodiments in which the present invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present invention. It should be understood that the various embodiments of the present invention, while different from each other, are not necessarily mutually exclusive. For example, specific shapes, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the present invention. Furthermore, it should be understood that the positions or arrangements of individual components within each disclosed embodiment may be modified without departing from the spirit and scope of the present invention. Accordingly, the following detailed description is not intended to be limiting, and the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly described. Like reference numerals in the drawings designate the same or similar functionality throughout the several aspects.

[0046] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0047] First, Fig. 1 is a diagram showing the overall configuration of a battery rack fire suppression system of a UPS according to the first embodiment of the present invention. Fig. 2 is a plan view of a battery rack fire suppression system of a UPS according to the first embodiment of the present invention. Fig. 3 is a side view of a battery rack fire suppression system of a UPS according to the first embodiment of the present invention. Fig. 4 is a diagram showing a state in which a detection unit is installed on the upper part of a case in which a case equipped with a battery rack is continuously installed.

[0048] The battery rack fire suppression system of the uninterruptible power supply according to the first embodiment of the present invention may include a body (100), a flame retardant cloth operating unit (200), a fire extinguishing unit (300), a detection unit (400), a water tank (500), and a drain pipe (600).

[0049] The above-mentioned body (100) is formed in a roughly rectangular shape, and is equipped with a battery rack (110) that is open at the front and rear and closed on both sides with vertical plates.

[0050] Inside the above battery rack (110), a plurality of battery modules (120) are mounted at regular height intervals.

[0051] The body (100) including the battery rack (110) and battery module (120) can be arranged in series with a certain distance between them in the front and rear directions.

[0052] The above flame retardant fabric operating part (200) can be installed on the upper part of the body (100).

[0053] The flame retardant cloth operating unit (200) is configured so that the flame retardant cloth (220) is raised in normal times when no fire occurs, and when a fire occurs, the power is cut off, and when the power is cut off, the fixing force of the clutch (240) is released, lowering the flame retardant cloth (220).

[0054] The above flame retardant cloth operating part (200) may include a rotating shaft (210), a flame retardant cloth (220), and a driving motor (230).

[0055] The above rotation axis (210) can be wound with a flame retardant fabric (220) of a certain length.

[0056] The rotation axis (210) is rotatably fixed to an inner frame (211) fixed to the upper inner side of the body (100).

[0057] The above rotation shafts (210) are mounted on both sides of the upper portion of the body (100), and one rotation shaft (210) is coupled to an inner frame (211), and the other rotation shaft (210) is coupled to a clutch (700) that is fixed to the inner frame (211).

[0058] The above flame retardant fabric (220) can be wound to a certain length around the rotation axis (210).

[0059] In the event of a fire, the fire retardant sheet (220) is quickly lowered to close the front and rear of the hull (100) and create a suffocating state, thereby preventing the spread of fire.

[0060] A weight (221) can be fixed to the lower part of the above flame retardant fabric (220) so that it can be lowered by its own weight.

[0061] The above driving motor (230) is fixed to the inner frame, and the pulley of the driving motor (230) and the pulley mounted on the rotation shaft (210) are connected through a chain.

[0062] The drive motor (230) is driven by a 24V DC power source to wind the flame retardant cloth (220) around the rotation shaft (210), and when the winding of the flame retardant cloth (220) is completed, it is maintained by a 12V DC power source.

[0063] The drive motor (230) can also rotate the rotation shaft (210) to rewind the flame retardant cloth (220) that has descended to the bottom of the tank (500) in the event of a malfunction of the fire suppression system or a non-large fire.

[0064] In addition, the fire extinguishing unit (300) can prevent the spread of fire by spraying water to the front and rear of the battery module (120) when a fire occurs.

[0065] The above digestion unit (300) includes a water supply pipe (320), a branch pipe (340), and a digestion nozzle (350).

[0066] The above water supply pipe (320) is a pipe through which water is supplied from the outside, and the water supply pipe (320) is located at the top of the battery rack (110).

[0067] The above branch pipes (340) are pipes that are connected to each water supply pipe (320) and distribute the water supplied through the water supply pipe (320) and supply it to the fire extinguishing nozzle (350).

[0068] The branch pipe (340) may be equipped with a deformable corrugated pipe (341) so that it can be accurately positioned on both sides of the battery rack (110) regardless of the size or height of the battery rack (110). Accordingly, the branch pipe (340) can be accurately positioned on both sides of each battery module (120), enabling water to be accurately and quickly supplied to the battery module (120).

[0069] Referring to FIGS. 5 and 6, the fire extinguishing nozzle (350) is mounted at regular intervals on the branch pipe (340) to spray water.

[0070] The fire extinguishing nozzles (350) can be mounted in an alternating manner with respect to the battery module (120).

[0071] For example, the fire extinguishing nozzle (350) located on one side of the battery module (120) is located on the 1st, 3rd, and 5th (odd-numbered) battery modules (120) from the bottom among the battery modules (120), and the fire extinguishing nozzle (350) located on the other side is located on the 2nd, 4th, and 6th (even-numbered) battery modules (120).

[0072] When the fire extinguishing nozzle (350) is mounted on the branch pipe (340), it can be mounted at a certain angle so that the fire extinguishing agent can be sprayed into the inside of the battery module (120).

[0073] That is, since the fire extinguishing nozzles (350) are mounted at a certain height interval at the front and rear of the battery module (120), the fire extinguishing agent can be sprayed evenly on the battery module (120) rather than spraying the fire extinguishing agent from the top of the body (100), and fire extinguishing in the battery module (120) can be more effectively performed.

[0074] In addition, since the fire extinguishing nozzle (350) is mounted at an angle toward the inside of the battery module (120), it sprays the fire extinguishing agent deep into the inside of the battery module (120) rather than spraying the fire extinguishing agent on the front and rear of the battery module (120), thereby enabling the fire to be extinguished more quickly and effectively. Accordingly, when spraying the fire extinguishing agent on the battery module (120), blind spots can be minimized so that there is no place where the fire extinguishing agent is not sprayed, thereby enabling the fire to be extinguished stably.

[0075] In addition, the above detection unit (400) is installed on the upper part of the body (100) and can detect temperature, smoke, flames, etc. generated from the battery module (120).

[0076] The detection unit (400) is installed on the upper part of the body (100), but is installed facing forward from the rear of the battery module (120).

[0077] The above detection unit (400) is installed with a horizontal fixing member (410) at an upper portion spaced apart from the body (100) at a certain height. The fixing member (410) may be installed on the ceiling or the upper portion of the side wall to fix the detection unit (400).

[0078] Here, the above detection unit (400) may be a thermal imaging camera.

[0079] The detection unit (400) detects temperature, smoke, flames, etc. generated from the battery module (120) in real time, and the detected data is transmitted to the control unit (420).

[0080] The above control unit (420) updates data such as temperature, smoke, and flame detected by the detection unit (400) in real time, and if the detected data exceeds the standard value, the power of the fire suppression system is cut off and the fire extinguishing agent is sprayed through the fire extinguishing unit (300).

[0081] The above tank (500) extinguishes the battery module (120) and stores a certain amount of falling water when water is sprayed through the fire extinguishing unit (300) due to a fire.

[0082] The tank (500) must be formed to have a larger cross-sectional area than the body (100), and the height of the tank (500) must be 40 cm or more.

[0083] The above drain pipe (600) discharges water stored inside the tank (500) to the outside. The drain pipe (500) may be equipped with an opening / closing valve (610).

[0084] When a certain amount of digestive fluid stored in the tank (500) is stored, the opening / closing valve (610) can be opened to discharge the digestive fluid to the outside.

[0085] The above opening / closing valve (610) can be manually operated by the worker to open / close the flow path.

[0086] The above-mentioned opening / closing valve (610) is connected to the control unit (420) and can be controlled through the control unit (420). A water level sensor is installed inside the water tank (500) to detect the water level of the water stored in the water tank (500). Accordingly, the control unit (420) can open the opening / closing valve (610) when the water level detected by the water level sensor exceeds a reference value.

[0087] In addition, referring to FIG. 7, the clutch (700) is mounted on an inner frame (211) on one side of the rotation shaft (210) of the flame retardant cloth operating part (200).

[0088] The clutch (700) is used to fix the rotating shaft (210) with the flame retardant sheet (220) wound on it so that it does not rotate in normal times when no fire is detected, and when fire or smoke is detected, the power supply is cut off to release the fixing force that was fixing the rotating shaft (210), thereby creating conditions in which the rotating shaft (210) can rotate.

[0089] The clutch (700) may be an electronic clutch.

[0090] A clutch (700) may include a hub (710) fixed to a rotating shaft (210), a non-rotating female coil (720) fixed to a yoke, an armature (730) positioned close to the hub (710), and a rotor (740) fixed to the armature (730) and having a pulley formed on an outer surface thereof, and this clutch has the same structure as a conventional one.

[0091] That is, when the clutch is excited by energizing the female coil (720), the armature (730) moves axially and is absorbed into the cross section of the hub (710), thereby transmitting the torque of the rotating shaft (210) from the armature (730). When the female coil (720) is not energized, the restoring force of the elastic body separates the armature (730) from the hub (710) by a small gap, so that the torque of the rotating shaft (210) is not transmitted.

[0092] In addition, referring to FIGS. 10 to 13, the fire extinguishing unit (300) can also extinguish a fire by spraying water or extinguishing agent.

[0093] The above digestion unit (300) includes a digestion cabinet (310), a water supply pipe (320), a supply pipe (330), a branch pipe (340), and a digestion nozzle (350).

[0094] The above digestive cabinet (310) can be installed at any location outside the body (100).

[0095] The digestive cabinet (310) has a certain amount of digestive fluid stored inside, and the digestive fluid is pumped and supplied by the operation of the pump (311).

[0096] The above water supply pipe (320) is a pipe through which water is supplied from the outside, and the water supply pipe (320) is located at the top of the battery rack (110).

[0097] The above supply pipe (330) is a pipe that supplies the extinguishing agent stored in the extinguishing agent cabinet (310), and the pump can be installed on the supply pipe (330).

[0098] One end of the supply pipe (330) is connected to the digestion cabinet (310), and the other end is connected to the water supply pipe (320).

[0099] The above branch pipes (340) are pipes that are connected to the water supply pipes (320) and distribute the water or extinguishing agent supplied through the water supply pipes (320) and supply them to the extinguishing nozzles (350).

[0100] The branch pipe (340) may be equipped with a deformable corrugated pipe (341) so that it can be accurately positioned on both sides of the battery rack (110) regardless of the size or height of the battery rack (110). Accordingly, the branch pipe (340) can be accurately positioned on both sides of each battery module (120), enabling water or extinguishing agent to be accurately and quickly supplied to the battery module (120).

[0101] The above fire extinguishing nozzle (350) is mounted at regular intervals on the branch pipe (340) and sprays water or fire extinguishing agent.

[0102] The fire extinguishing nozzles (350) can be mounted in an alternating manner with respect to the battery module (120).

[0103] A control valve (360) may be mounted on the above water supply pipe (320) and supply pipe (330).

[0104] The control valve (360) can control the supply of water and extinguishing agent supplied to the water supply pipe (320) and the supply pipe (330), respectively.

[0105] That is, when a fire occurs, the control valve (360) on the water supply pipe (320) side is closed, the control valve (360) on the supply pipe (330) side is opened, and the fire extinguishing agent is supplied from the fire extinguishing agent cabinet (310) through the supply pipe (330) to initially extinguish the fire in the battery module (120).

[0106] If the fire is not extinguished until all the extinguishing fluid is exhausted, the control valve (360) on the water supply pipe (320) side is opened and the control valve (360) on the supply pipe (330) side is closed so that water is supplied through the water supply pipe (320) to extinguish the fire in the battery module (120).

[0107] The above control valve (360) is connected to the control unit (420), and the supply of water or extinguishing agent can be controlled through the control of the control unit (420).

[0108] In addition, the above tank (500) may include a digestion liquid splash prevention unit (800) that prevents the digestion liquid from splashing in all directions when the digestion liquid is sprayed from the digestion unit (300).

[0109] The above digestive juice splash prevention unit (800) may include a cover (810), a support (820), a rack (830), a support frame (840), and a motor (850).

[0110] The above cover (810) is fixed to the inside of the tank (500) and installed so as to be able to be lifted.

[0111] The cover (810) is made of multi-level folds and can be raised and lowered, and a connecting frame (811) that connects the cover (810) and the support (820) is fixed to the upper part. Accordingly, the shape of the cover (810) is maintained constant under normal conditions, and when fire extinguishing agent is sprayed due to a fire, the cover (810) is raised and lowered to the same height by the connecting frame (811).

[0112] The above support (820) is fixed to a connecting frame (811) fixed to the upper part of the cover (810) and serves to lift the cover (810).

[0113] The above rack (830) can be installed vertically on the outside of the tank (500).

[0114] The lower part of the rack (830) can be fixed to the outer surface of the tank (500), and the upper part can be fixed to the upper bottom surface of the support (820).

[0115] The above support frame (840) is installed on the outside of the tank (500) to stably support the motor (850), and the motor (850) is fixed to the upper part of the support frame (840).

[0116] The above motor (850) is equipped with a pinion gear and engages with the rack (830), and the pinion gear rotates as the motor (850) drives the rack (830) upwards. Accordingly, when the cover (810) is raised to a certain height from the tank (500) and the extinguishing agent is sprayed, the phenomenon of the extinguishing agent splashing in all directions can be prevented.

[0117] A stopper (860) may be provided on the inner lower part of the above tank (500).

[0118] When the cover (810) is lowered into the tank (500) by driving the above motor (850), the rack (830) is lowered as a whole by the rotation of the pinion gear, and when the lowering of the rack (830) is completed, the lower part of the rack (830) is caught by the stopper (860) and supported so that it does not lower any further.

[0119] Additionally, a check valve (900) may be mounted on the branch pipe (340) of the above digestion unit (300).

[0120] The above check valve (900) can be connected to the control unit (420) and controlled respectively.

[0121] The above-mentioned hull (100) is installed continuously in the front and rear directions at a certain distance apart, and inside the hull (100), a battery rack (110) equipped with a battery module (120) is installed continuously in the left and right directions.

[0122] That is, when fire or smoke is detected in any one of the continuously installed battery racks (110), the control unit (420) opens the check valve (900) of the branch pipe (340) located in the corresponding battery rack (110) so that water can be sprayed through the fire extinguishing nozzle (350).

[0123] Accordingly, water can be sprayed only on battery racks (110) where fire or smoke is detected, without spraying water on battery racks (110) where fire or smoke is not detected, thereby preventing unnecessary loss of battery racks (110).

[0124] In addition, the front and rear of the above-mentioned body (100) further include a guide part (910) that guides the lowering of the flame retardant cloth (220).

[0125] The guide part (910) includes a support (911) and a guide rail (912).

[0126] The above support (911) is formed vertically on both the front and rear sides of the body (100) to reinforce the rigidity of the body (100).

[0127] The above guide rail (912) is fixed in a bent shape in the inner direction of each support (911) and guides the raising and lowering of the flame retardant fabric (220).

[0128] The above guide rail (912) accommodates both ends of the flame retardant fabric (220) to suffocate the body (100) to the maximum extent possible.

[0129] In addition, referring to FIG. 8, when the flame retardant fabric (220) descends along the guide rail (912), a shock absorbing part (920) may be further included to elastically absorb the shock generated when the weight plate (221) at the bottom of the flame retardant fabric (220) hits the bottom of the body (100).

[0130] The above shock absorbing member (920) includes an outer case (9921), a first buffer member (922), a partition (923), an elastic member (924), and a second buffer member (925).

[0131] The above outer case (921) is connected to the lower part of the body (100), and a hook is formed at the lower part to prevent it from being detached from the body (100) while performing the raising and lowering operation.

[0132] The first buffer member (922) is attached to the upper inner side of the outer case (921) and the upper part protrudes upward from the outer case (921) to primarily buffer the impact when the flame retardant fabric (220) is lowered.

[0133] The above-mentioned partition (923) is formed of metal or resin material and separates the elastic member (924) and the buffer member (925).

[0134] The above elastic member (924) is formed of an elastic material to secondary absorb the impact when the flame retardant fabric (220) is lowered.

[0135] The above second buffer member (925) is formed of a sponge material that can effectively absorb shock and is installed between elastic members (924).

[0136] In addition, when the flame retardant fabric (220) is completely lowered to the lower part of the body (100), an anti-lifting unit may be further included to prevent the weight plate (221) at the lower part of the flame retardant fabric (220) from being bounced upward when the rebound force of the shock absorbing unit (920) occurs.

[0137] The above anti-lifting member is formed with a support rib (926) formed on the outside of the guide rail (912), and an anti-lifting member (927) is mounted on the support rib (926) so as to rotate around an axis.

[0138] A spring (928) is mounted on the above axis to restore the initial state after the anti-lift member (927) rotates, thereby supporting the upper part of the weight plate (221) after the flame retardant cloth (220) is lowered, thereby preventing the flame retardant cloth (220) from being bounced upward.

[0139] In addition, referring to FIG. 9, when the flame retardant fabric (220) is lowered to the lower part of the body (100) along the guide rail (912), an anti-wrinkle part (930) may be further included to ensure that both ends of the flame retardant fabric (220) located inside the guide rail (912) are spread out taut without being wrinkled.

[0140] The above anti-wrinkle part (930) includes a striking rib (931), a support frame (932), an anti-wrinkle member (933), and an operating space (934).

[0141] The above striking rib (931) is formed to protrude on both sides of the upper part of the weight plate (221) fixed to the lower part of the flame retardant cloth (220), and is formed to slope inward from the top to the bottom.

[0142] The above support frame (932) is each fixed to the outer side of the guide rail (912), and the inner and outer directions of the guide rail (912) are formed in an open shape.

[0143] The above anti-wrinkle member (933) is rotatably fixed to the inside of the support frame (932) through an axis, and is rotated by the impact of the impact rib (931) when the flame retardant cloth (220) is lowered.

[0144] The above anti-wrinkle member (933) includes a striking plate (933a) and an anti-wrinkle guide (933b).

[0145] The above striking plate (933a) is positioned at the lower part of the striking rib (931), and the anti-wrinkle guide (933b) is formed at a certain angle from the striking plate (933a) and is positioned on the inside of the support frame (932).

[0146] The above striking plate (933a) and the anti-wrinkle guide (933b) form an obtuse angle.

[0147] The above operating space (934) is a space formed through the guide rail (912) and in which the anti-wrinkle member (933) rotates.

[0148] In addition, a support piece (935) is formed on the inside of the support frame (932) to support the anti-wrinkle guide (933b) of the anti-wrinkle member (933) to prevent the anti-wrinkle guide (933) from rotating under normal conditions.

[0149] An elastic piece (936) is formed on the inner lower part of the above support frame (932) to allow the impact plate (933a) to rotate elastically when the anti-wrinkle member (933) rotates due to the lowering of the flame retardant fabric (220).

[0150] A stopper (937) is formed at the bottom of the support piece (935) on one side of the elastic piece (936), and after the anti-wrinkle member (933) rotates due to the lowering of the flame retardant cloth (220), the striking plate (933a) is supported so that it does not rotate any further.

[0151] As described above, when the anti-wrinkle member (933) rotates due to the lowering of the flame retardant fabric (220), the anti-wrinkle guide (933b) is positioned close to or in close contact with both sides of the flame retardant fabric (220), so that the flame retardant fabric (220) is spread out tautly.

[0152] For example, in a state where there is no anti-wrinkle member (933), when the flame retardant fabric (220) is lowered, if it is not properly guided by the guide rail (912) or by the rebound force due to the floor impact, the flame retardant fabric (220) may become wrinkled, resulting in a poor suffocation state of the body (100). However, the anti-wrinkle member (930) can prevent this phenomenon.

[0153]

[0154] In addition, the battery rack fire suppression system of the uninterruptible power supply, which is the second embodiment of the present invention, includes a battery rack (10), a frame (20), a first operating unit (30), a flame retardant cloth (40), a second operating unit (50), a water tank (60), a waterproof cloth (70), a water spray unit (80), and a water replenishment unit (90), as shown in FIGS. 14 to 17.

[0155] The above battery rack (10) is formed in a roughly rectangular shape, and a plurality of battery modules (M) are mounted inside at regular height intervals.

[0156] The above battery rack (10) is formed so that both sides and the upper surface are closed and the front and rear are open.

[0157] The above battery rack (10) is formed in a roughly rectangular shape, and has a structure in which the front, rear, and top are open, and both sides are closed by fixing a transfer prevention plate (11).

[0158] The above battery rack (10) is individually manufactured in a customized manner so that it can be installed continuously on the left and right.

[0159] The above battery rack (10) is connected to each corner and the upper and lower parts by angles (12) to form a basic frame, and a number of uninterruptible power supply devices (UPS) and battery modules are installed inside.

[0160] The above-mentioned transfer prevention plate (11) closes both sides of the battery rack (10), so that even if a fire occurs in the battery rack (10), it prevents the fire from spreading to the battery racks (10) installed on one or both sides.

[0161] The above frame (20) is installed to maintain a certain distance from the outside of the battery rack (10).

[0162] The above frame (20) is closed on both sides by vertical plates (21), and an upper fixing plate (22) is fixed to the upper part to increase the rigidity of the frame (20).

[0163] The above upper fixed plate (22) has a shape that protrudes outward more than the vertical plate (21).

[0164] The guide roller (53) of the second operating part (50) is fixed to the inside of both sides of the upper fixed plate (22) and the double-structured wheel (511) fixed to the shaft (51) is protected from being exposed to the outside.

[0165] For example, when only one battery rack (10) is installed, the frame (20) may be installed at a certain distance from the battery rack (10) and may be installed in a structure that surrounds the battery rack.

[0166] In addition, when the battery racks (10) are installed in a row on the left and right to form a group of five battery racks (10), the frame (20) can be formed to a size that can wrap around all five battery racks (10).

[0167] That is, the battery rack (10) is individually manufactured and has a structure that can be installed continuously left and right, and the frame (20) is manufactured in a size that can cover all of the installed battery racks (10) regardless of the number of battery racks (10).

[0168] The above first operating part (30) is installed on the upper part of the frame (20) and lowers the flame retardant cloth (40).

[0169] The above first operating part (30) includes a support member (31), a shaft (32), a driving motor (33), a driving chain (34), and a clutch (35).

[0170] The above support member (31) is a structure fixed to the inside of the vertical plate (21) of the frame (20) to install a shaft (32), and the above support member (31) is manufactured by bending a metal plate.

[0171] Among the above support members (31), one side of the support member (31) can be folded in multiple stages to secure the driving motor (33).

[0172] Among the above support members (31), the support member (31) on the other side is bent into a square shape and fixed to the inside of the vertical plate (21) to support the end of the shaft (32).

[0173] The above shaft (32) is connected to a support member (31) that is folded in multiple stages at one end and rotates by a bearing, and the other end of the shaft (32) is connected to a support member (31) that is folded in a square shape.

[0174] The above driving motor (33) is fixed to the bent end of the support member (31) on one side, and the driving chain (34) is connected to a wheel formed on the shaft of the driving motor (33) and a wheel formed on the shaft (32), thereby rotating the shaft (32) by driving the driving motor (33).

[0175] The above driving motor (33) can also rotate the shaft (32) to rewind the flame retardant fabric (40) lowered to the lower part of the frame (20) in the event of a malfunction of the fire prevention system or a non-large fire.

[0176] The above clutch (35) is installed at one end of the shaft (32) to control the rotation of the shaft (32), and the clutch (35) is coupled to the end of the shaft (32) inside the support member (31) on one side.

[0177] The above clutch (35) is normally powered when fire and smoke are not detected, and thus the clutch (35) holds the shaft (32) in place, thereby preventing the shaft (32) from rotating.

[0178] When fire or smoke is detected through the sensor unit, the control unit stops supplying power to the clutch (35), and the pressure of the clutch (35) holding the shaft (32) is released, causing the shaft (32) to rotate.

[0179] The above shaft (32) can be controlled to rotate by a control unit, and when a power outage occurs due to a fire, the supply of electricity to the clutch (35) is cut off, and the pressure of the clutch (35) holding the shaft (32) is released, allowing the shaft (32) to rotate.

[0180] Here, the clutch (35) may use an electromagnetic clutch that controls the rotation of the shaft (32) by using the magnetic force of an electromagnet. Since the clutch has the same structure as a conventional clutch, a detailed description thereof will be omitted.

[0181] In addition, the flame retardant cloth (40) is wound to a certain length on the shaft (32) of the first operating unit (30). Before fire or smoke is detected, the flame retardant cloth (40) is wound on the shaft (32) so that the front and rear of the battery rack (10) are open, and when fire or smoke is detected, the flame retardant cloth (40) is quickly lowered by its own weight, enabling a quick response to the fire.

[0182] A weight plate (41) having a certain weight is attached to the inside and outside of the lower part of the flame retardant fabric (40), and at least one rivet (42) is fastened to the weight plate (41) to fix the weight plate (41) to the flame retardant fabric (40).

[0183] The above second operating part (50) is installed on the upper part of the frame (20) and is configured to raise the waterproof cover (70).

[0184] The second operating part (50) includes a driving shaft (51), a driving motor (52), a guide roller (53), and a wire (54).

[0185] The above driving shaft (51) is installed horizontally in the upper center of the frame (20), and a double-structured wheel (511) is fixed to both ends of the driving shaft (51).

[0186] The above wheel (511) is formed in duplicate so that wires (54) are connected to each side based on the driving shaft (51).

[0187] A driving motor (52) that rotates the driving shaft (51) is installed at one end of the driving shaft (51).

[0188] The above guide rollers (53) are fixed to the upper sides of the frame (20) on both sides and rotate to guide the wire (54). One end of the wire (54) is wound around a double-structured wheel (511), and the other end is connected to the lower support (71) of the waterproof cloth (70).

[0189] The driving motor (52) of the first operating unit (50) can lower the waterproof sheet (70) that has risen toward the middle of the frame (20) again and fold it and store it inside the water tank (60) in case of a malfunction of the fire prevention system or a non-large fire.

[0190] In addition, when fire or smoke is detected, the reservoir (60) prevents the spread of fire by storing a certain amount of water inside the reservoir (60) through a water supply means provided on one side of the reservoir (60) or on the upper part of the frame (20).

[0191] The above reservoir (60) must be formed to be larger than the cross-sectional area of ​​the frame (20), and the height of the reservoir (60) is formed to be 60 cm.

[0192] The above water supply means may be installed in the form of a pipe on the upper part of the reservoir (60), and a drain pipe (not shown) may be installed on one side of the reservoir (60) to drain the water stored therein.

[0193] In addition, the waterproof cover (70) can be raised by the operation of the second operating unit (50) to store a certain amount of water in the reservoir (60).

[0194] The above waterproof cloth (70) is normally stored folded inside the water tank (60) when no fire or smoke is detected, and when fire or smoke is detected by the sensor and the detection temperature is 80 to 90°C or higher, the drive shaft (51) rotates to unfold and raise the waterproof cloth (70).

[0195] At this time, the waterproof cloth (70) rises to a height of 40 cm from the upper part of the reservoir (60).

[0196] The above waterproof cover (70) is connected between the lower support (71) and the fixed support (72), the lower support (71) is fixed to the lower end of the wire (54) of the second operating part (50), and the fixed support (72) is fixed to the bottom inside the reservoir (60).

[0197] In addition, the water injection unit (80) can quickly extinguish a fire by pumping and spraying water stored in the reservoir (60) to the upper part of the battery rack (10).

[0198] The above water injection unit (80) includes a pumping motor (81), a supply pipe (82), and a injection nozzle (83).

[0199] The above pumping motor (81) is mounted inside the reservoir (60) to pump water stored in the reservoir (60), and the supply pipe (82) supplies water pumped from the pumping motor (81) to the upper part of the battery rack (10).

[0200] The above injection nozzle (83) is fixed to the end of the supply pipe and sprays water pumped through the supply pipe (82) from the top of the battery rack (10), so that a fire occurring in the battery rack (10) can be quickly extinguished.

[0201] Here, both sides of the battery rack (10) are formed into a closed structure through a heat-resistant material transfer prevention plate (11), so that fire is prevented from spreading to other battery racks (10) installed in succession on one or both sides of the battery rack (10), thereby reducing the spread of fire and minimizing damage.

[0202] In addition, when the water replenishment unit (90) sprays water onto the battery rack (10) through the spray nozzle (83), a certain amount of water stored in the reservoir (60) is evaporated by heat, and the reservoir (60) is replenished with water equal to the evaporated water level.

[0203] The above water replenishment unit (90) includes a water level detection sensor (91), a water replenishment pipe (92), and a valve (93).

[0204] The above water level detection sensor (91) is installed inside the water tank (60) and detects the water level of the water stored inside the water tank (60).

[0205] The above water replenishment pipe (92) replenishes water inside the reservoir (60) by the amount of water evaporated by heat, and it is preferable that the water replenishment pipe (92) be placed above the waterproof sheet (70) so as not to interfere with the waterproof sheet (70) rising to the upper part of the reservoir (60).

[0206] The above valve (93) is installed on the water replenishment pipe (92) and opens when water is replenished, and closes when water replenishment is completed.

[0207] That is, when the water level of the reservoir (60) is detected by the water level detection sensor (91), the water replenishment unit (90) transmits the detected water level information to the control unit.

[0208] The control unit controls the valve (93) to open, and water is replenished into the water tank (60) through the water replenishment pipe (92). The water level sensor (91) transmits a detection signal to the control unit when the water in the water tank (60) reaches a certain level, and the control unit controls the valve (93) to close the water replenishment pipe (92).

[0209] In addition, a guide portion (1100) formed before and after the frame (20) may be further included.

[0210] The above guide part (1100) includes a support (1101) and a guide rail (1102).

[0211] The above support (1101) is formed vertically on both front and rear sides of the frame (20) to reinforce the rigidity of the frame (20).

[0212] The above guide rail (1102) is fixed in a bent shape in the inner direction of each support (1101) and guides the raising and lowering of the flame retardant fabric (40).

[0213] The above guide rail (1102) accommodates both ends of the flame retardant fabric (40) to suffocate the battery rack (10) as much as possible.

[0214] In addition, referring to FIG. 21, when the flame retardant fabric (40) descends along the guide rail (1102), a shock absorbing part (1110) may be further included to elastically absorb the shock generated when the weight plate (41) at the bottom of the flame retardant fabric (40) hits the bottom of the frame (20).

[0215] The above shock absorbing member (1110) includes an outer case (1111), a first buffer member (1112), a partition (1113), an elastic member (1114), and a second buffer member (1115).

[0216] The above outer case (1111) is connected to the lower part of the frame (20), and a hook is formed at the lower part to prevent it from being detached from the frame (20) while performing the up-and-down operation.

[0217] The first buffer member (1112) is attached to the upper inner side of the outer case (1111) and the upper part protrudes upward from the outer case (1111) to primarily buffer the impact when the flame retardant fabric (40) is lowered.

[0218] The above-mentioned partition (1113) is formed of metal or resin material and separates the elastic member (1114) and the buffer member (1115).

[0219] The above elastic member (1114) is formed of an elastic material to secondary absorb the impact when the flame retardant fabric (40) is lowered.

[0220] The above second buffer member (1115) is formed of a sponge material that can effectively absorb shock and is installed between elastic members (1114).

[0221] In addition, when the flame retardant fabric (40) is completely lowered to the lower part of the frame (20), a rebound force of the shock absorbing part (1110) is generated, an anti-lifting part may be further included to prevent the weight plate (41) at the lower part of the flame retardant fabric (40) from being bounced upward.

[0222] The above anti-lifting member is formed with a support rib (1116) formed on the outside of the guide rail (1102), and an anti-lifting member (1117) is mounted on the support rib (1116) so as to rotate around an axis.

[0223] A spring (1118) is mounted on the above axis to restore the initial state after the anti-lift member (1117) rotates, thereby supporting the upper part of the weight plate (41) after the flame retardant cloth (40) is lowered, thereby preventing the flame retardant cloth (40) from being bounced upward.

[0224] In addition, referring to FIGS. 22 and 23, when the flame retardant fabric (40) is lowered to the lower part of the frame (20) along the guide rail (1102), an anti-wrinkle part (1120) may be further included to ensure that both ends of the flame retardant fabric (40) located inside the guide rail (1102) are spread out taut without being wrinkled.

[0225] The above anti-wrinkle part (1120) includes a striking rib (1121), a support frame (1122), an anti-wrinkle member (1123), and an operating space (1124).

[0226] The above striking rib (1121) is formed to protrude on both sides of the upper part of the weight plate (41) fixed to the lower part of the flame retardant cloth (40), and is formed to slope inward from the top to the bottom.

[0227] The above support frame (1122) is each fixed to the outer side of the guide rail (1102), and the inner and outer directions of the guide rail (1102) are formed in an open shape.

[0228] The above anti-wrinkle member (1123) is rotatably fixed to the inside of the support frame (1122) through an axis, and is rotated by the impact of the impact rib (1121) when the flame retardant cloth (40) is lowered.

[0229] The above anti-wrinkle member (1123) includes a striking plate (1123a) and an anti-wrinkle guide (1123b).

[0230] The above striking plate (1123a) is positioned at the lower part of the striking rib (1121), and the anti-wrinkle guide (1123b) is formed at a certain angle from the striking plate (1123a) and is positioned on the inside of the support frame (1122).

[0231] The above striking plate (1123a) and the anti-wrinkle guide (1123b) form an obtuse angle.

[0232] The above operating space (1124) is a space formed through the guide rail (1102) and in which the anti-wrinkle member (1123) rotates.

[0233] In addition, a support piece (1125) is formed on the inside of the support frame (1122) to support the anti-wrinkle guide (1123b) of the anti-wrinkle member (1123) to prevent the anti-wrinkle guide (1123) from rotating under normal conditions.

[0234] An elastic piece (1126) is formed on the inner lower part of the above support frame (1122) to allow the impact plate (1123a) to rotate elastically when the anti-wrinkle member (1123) rotates due to the lowering of the flame retardant fabric (40).

[0235] A stopper (1127) is formed at the bottom of the support piece (1125) on one side of the elastic piece (1126), and after the anti-wrinkle member (1123) rotates due to the lowering of the flame retardant cloth (40), the striking plate (1123a) is supported so that it does not rotate any further.

[0236] As described above, when the anti-wrinkle member (1123) rotates due to the lowering of the flame retardant fabric (40), the anti-wrinkle guide (1123b) is positioned close to or in close contact with both sides of the flame retardant fabric (40), so that the flame retardant fabric (40) is spread out tautly.

[0237] For example, in a state where there is no anti-wrinkle member (1123), when the flame retardant fabric (40) is lowered, if it is not properly guided by the guide rail (1102) or by the rebound force due to the floor impact, the flame retardant fabric (40) may be wrinkled, resulting in a poor suffocation state of the battery rack (10). However, the anti-wrinkle member (1120) of the present invention can prevent this phenomenon.

[0238] That is, with reference to FIGS. 19 and 20, the battery rack fire suppression system of the uninterruptible power supply of the present invention detects fire through a temperature or smoke-detecting sensor unit installed in the frame (20) or in a location close to the frame (20) when fire or smoke is detected, and when fire is detected, the control unit controls the first operating unit (30) and the second operating unit (50).

[0239] As described above, when fire or smoke is detected through the sensor unit, the control unit stops supplying power to the clutch (35), and the pressure of the clutch (35) holding the shaft (32) is released, causing the shaft (32) to rotate.

[0240] The above shaft (32) can be controlled to rotate by a control unit, and when a power outage occurs due to a fire, the power supply to the clutch (35) is cut off, and the pressure of the clutch (35) holding the shaft (32) is released, allowing the shaft (32) to rotate.

[0241] The flame retardant cloth (40) wound on the shaft (32) is quickly lowered to the lower part of the frame (20) as the shaft (32) rotates due to the load of the weight plate (41) fixed to the lower part.

[0242] As described above, when the flame retardant fabric (40) is lowered to the bottom of the frame (20), the front and rear of the battery rack (10) are closed, putting the battery rack (10) into a suffocating state, thereby quickly extinguishing the fire and preventing further spread of the fire.

[0243] In addition, if the temperature within the battery rack (10) or frame (20) is higher than the set temperature, the control unit operates the drive motor (52) of the second operating unit (50) to raise the wire (54), and as the wire (54) rises, the waterproof sheet (70) rises to the middle part of the frame (20) and is spread out.

[0244] At this time, water is supplied through a water supply means, and the supplied water is stored at a certain level inside a reservoir (60), and the water stored in this way submerges the battery module (M) located in the middle of the frame (20) to prevent the spread of fire.

[0245] The water stored in the above reservoir (60) is pumped through the pumping motor (81) and sprayed onto the upper part of the battery rack (10) through the spray nozzle (83).

[0246] That is, the present invention can effectively extinguish the fire by spraying water through a sprinkler from the ceiling and additionally spraying water through a spray nozzle (83) of a water spray unit (80) when a fire occurs in the battery rack (10).

[0247] In addition, in the process of extinguishing a fire, a certain amount of water stored in the reservoir (60) may evaporate due to the heat generated. The water replenishment unit (90) detects the level of the evaporated water by the water level detection sensor (91) during the process of extinguishing a fire and replenishes water in the amount of evaporated water, thereby enabling the fire to be extinguished stably.
