Description

Technology Field

[0001] The present invention relates to a fire suppression system using electrical devices in multi-unit housing within the field of firefighting technology. More specifically, it relates to an improved fire suppression system using electrical devices in multi-unit housing that automatically detects the occurrence of a fire and suppresses it in the early stages when a fire occurs in an internal ceiling space that is obscured by ceiling panels and not visible to the naked eye. Background Technology

[0002] Fire extinguishing devices are installed in the form of sprinklers at regular intervals on the ceilings inside the building.

[0003] This fire extinguishing device sprays water radially from the center point when a fire occurs.

[0004] Building fires have the disadvantage that it is difficult to suppress the initial fire even if water is sprayed in a radial pattern when the fire occurs in the corners of the building interior where fire extinguishing devices are not installed.

[0005] Recently, fires occurring in large shopping malls, sports centers, or traditional markets can result in significant casualties and property damage.

[0006] In particular, the recent fire at the Jecheon Sports Center in Korea was caused by the exterior walls being manufactured using the Dryvit method, which allowed the fire to spread easily and uncontrollably, resulting in many casualties.

[0007] Dryvit is an insulating exterior material made of styrofoam coated with cement, and it is a material that is highly sensitive to fire and is used in many buildings.

[0008] The biggest reason for the failure to suppress the Jecheon Sports Center fire in its early stages was that sprinklers were installed on the underside of the ceiling panels, and the fire's ignition point was within the interior space of the ceiling panels, which amplified the heat and spread rapidly throughout the entire building along the exterior walls made of Dryvit material, making immediate detection and response to the fire impossible.

[0009] Therefore, conventional sprinklers had the problem that they could not quickly detect fires within the ceiling space or suppress them in the early stages because they were installed only on the underside of the ceiling panels. Prior art literature

[0017] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0018] Prior to describing the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein.

[0019] In addition, since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification. However, this is not intended to limit the embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention.

[0020] Prior to a detailed explanation, the system according to the present invention adopts the configuration of "Registered Patent No. 1895975 (August 31, 2018), Fire Monitoring and Suppression System Using Electrical Devices in Multi-unit Housing" as is. Accordingly, some of the contents described below are the configuration of the aforementioned registered patent and are to be cited as is.

[0021] As illustrated in the examples of FIGS. 1 to 6, the system according to the present invention installs a fire suppression device (110) in the ceiling interior space (40) above the ceiling panel (20) of a multi-unit dwelling (10), and forms a plurality of sensor modules (140, see FIG. 4) for monitoring fire at each coverage area in the ceiling interior space (40).

[0022] Although the fire suppression device (110) is exemplified as being installed in the ceiling interior space (40), it is not limited thereto and can also be installed in the lower interior space (30) of the ceiling panel (20).

[0023] Additionally, the fire suppression device (110) has a ball screw member (104) of a certain length formed across the center of the ceiling interior space (40), a first support (101) is connected to one end of the ball screw member (104), a drive motor (102) is connected to the other end of the ball screw member (104) on the opposite side, and a second support (103) is connected to the lower surface of the drive motor (102) to fix and support the drive motor (102).

[0024] And, the moving block part (111) shown in FIG. 3 is cylindrical in shape, and the ball screw member (104) passes through the central part and is joined, and screw threads are formed on the inner surface (112) that engage with the screw threads on the outer surface of the ball screw member (104).

[0025] The moving block (111) moves linearly in the axial direction of the ball screw member (104) according to the rotation of the ball screw member (104) by the driving force of the driving motor (102).

[0026] The moving block part (111) includes an inner cylinder (113) that surrounds the inner surface (112) and an outer cylinder (115) spaced apart from the inner cylinder (113) at a certain distance.

[0027] The inner cylinder (113) has a motor (117) coupled to its outer surface, and a pinion gear (114) coupled to the motor shaft (117a) of the motor (117) to rotate.

[0028] The outer cylinder (115) is spaced a certain distance from the inner cylinder (113) for 180-degree rotation.

[0029] The motor (117) is coupled to the outer surface of the inner cylinder (113) and is in a form that does not come into contact with the outer cylinder (115).

[0030] The outer cylinder (115) has a rack gear (116) formed along the inner circumference.

[0031] The rack gear (116) rotates according to the rotational movement of the pinion gear (114) while in a state where it is meshed with the pinion gear (114).

[0032] The moving block part (111) has a fire extinguishing liquid spraying part (120) attached to one side of its outer surface for discharging fire extinguishing liquid.

[0033] The fire extinguishing liquid spraying unit (120) is connected to a first spray nozzle (121), a second spray nozzle (122), and a third spray nozzle (123) that receive and spray fire extinguishing liquid from the outside.

[0034] The first spray nozzle (121) is connected to a fire pump (118) that pumps the fire extinguishing liquid from a fire extinguishing liquid tank (119) in which the fire extinguishing liquid is stored into the transfer pipe.

[0035] The first spray nozzle (121) forms a camera unit (130) on the upper outer surface to capture images of the fire monitoring area.

[0036] The interior of the first injection nozzle (121) includes a first pipe (121a) that forms a straight line, a second pipe (121b) formed to spread out toward the first injection nozzle (121) from the end forming the first straight pipe (121a), and a third pipe (121c) formed to narrow by connecting to the end forming the second pipe (121b).

[0037] A flow rate acceleration section (124) is formed in the center of the second conduit (121b) and the third conduit (121c) to rapidly accelerate the flow rate of the incoming digestive fluid.

[0038] The shape of the flow velocity acceleration part (124) is formed into a teardrop shape by making the front and back pointed so that fluid resistance is minimized.

[0039] The flow velocity acceleration unit (124) is fixedly supported in the second conduit (121b) or the third conduit (121c) through a connecting member (124a).

[0040] Inside the second injection nozzle (122), a fourth pipe (122a) is formed that is horizontally connected to one end of the third pipe (121c) and forms a straight line.

[0041] Inside the third injection nozzle (123), the fourth conduit (122a) is extended, and a first rotation shaft (126) with a first motor (126a) and a second rotation shaft (128) with a second motor (128a) are formed at both ends of one end of the fourth conduit (122a).

[0042] A first variable conduit (125) and a second variable conduit (127) are connected to the first rotation axis (126) and the second rotation axis (128), respectively.

[0043] The first variable pipe (125) and the second variable pipe (127) are rotated by the first rotating shaft (126) and the second rotating shaft (128) according to the driving of the first motor (126a) and the second motor (128a), so that the width gradually narrows toward the discharge port to form a straight line shape for the spray of the extinguishing liquid, or widens toward the discharge port to form a fan shape for the spray of the extinguishing liquid.

[0044] The pinion gear (114) rotates according to the driving of the motor (117), and accordingly, the rack gear (116) engaged with the pinion gear (114) rotates, causing the moving block (111) to rotate together.

[0045] The rotation of the moving block (111) causes the fire extinguishing liquid spraying unit (120) and the camera unit (130) to rotate back and forth in the ceiling interior space (40).

[0046] The sensor module (140) detects fire-related risks and represents a sensor group, and is one of a smoke sensor, a temperature sensor, and a flame sensor; in the present invention, for convenience of explanation, it is provided with a temperature sensor.

[0047] The sensor module (140) forms a sensor coverage area of ​​a certain zone that detects fire when a fire, which is a fire risk, occurs, and when a temperature value greater than a preset temperature is detected, it generates a fire detection signal and transmits it to the fire suppression device (110).

[0048] According to FIG. 6, the moving block unit (111) according to an embodiment of the present invention includes a control unit (105), an encoder (117b), a motor driving unit (106), a camera driving unit (107), a wireless communication unit (108), an infrared detection unit (109), and a storage unit (109a).

[0049] When the control unit (105) receives a fire detection signal from the sensor module (140), it obtains location information included in the fire detection signal. Here, the location information represents location information indicating a specific area within the ceiling interior space (40).

[0050] When the moving block (111) moves on the ball screw member (104), the control unit (105) receives the number of rotations of the motor (117) from the encoder (117b) coupled to the motor (117) and generates the position coordinates (X coordinates) of the moving block (111) on the ball screw member (104) corresponding to the number of rotations.

[0051] The control unit (105) continuously changes the position coordinates of the moving block part (111) on the ball screw member (104) according to the rotational speed of the motor (117).

[0052] The control unit (105) compares the position information of the acquired sensor module (140) with the position coordinates (X coordinates) of the moving block unit (111) on the ball screw member (104) corresponding to the rotational speed of the motor (117), calculates the X-axis distance information and direction information for the moving block unit (111) to move from its current position, and stores them in the storage unit (109a).

[0053] The control unit (105) receives a rotation angle measurement value from an encoder (117b) that is embedded in the motor (117) and measures the rotation angle of the motor (117), and calculates the angle value to be rotated by comparing the received rotation angle measurement value with calculated direction information.

[0054] The control unit (105) generates a rotation speed signal of the motor (117) based on the angle value to be rotated and transmits it to the motor drive unit (106), and rotates the pinion gear (114) by the rotation of the motor (117), and accordingly rotates the rack gear (116) engaged with the pinion gear (114) to rotate the moving block unit (111) and the fire extinguishing liquid spray unit (120) together toward the sensor module (140).

[0055] The control unit (105) controls the drive motor (102) to rotate the ball screw member (104) by the X-axis distance information to be moved, thereby moving the moving block unit (111) in a straight line.

[0056] When the control unit (105) generates a drive control signal and transmits it to the drive motor (102), the moving block unit (111) moves in a straight line, and the camera drive unit (107) is controlled to capture image information of the fire monitoring area by the camera unit (130) and to store the captured image information in the storage unit (109a).

[0057] The control unit (105) can transmit video information of the captured fire monitoring area to an external manager terminal or fire station center via the wireless communication unit (108).

[0058] The infrared detection unit (109) uses a photovoltaic cell to detect single-wavelength infrared emissions generated by flames in a fire monitoring area.

[0059] When the control unit (105) detects infrared emission from the infrared detection unit (109), it determines the location of the fire and operates the fire pump (118), and sprays fire extinguishing liquid from the fire extinguishing liquid tank (119) through the fire extinguishing liquid spraying unit (120) to quickly suppress the fire.

[0060] The control unit (105) continuously captures image information of a fire monitoring area at regular intervals by the camera unit (130), identifies a flame part in the captured image information, and selects pixels located at the outermost edge of the flame (13) part. That is, it derives a first line segment connecting the outermost pixels of the right end and the left end, and derives a second line segment connecting the outermost pixels of the top and bottom.

[0061] The control unit (105) calculates the area of ​​the flame (13) using the first line segment and the second line segment, and controls the first variable pipe (125) and the second variable pipe (127) to vary according to the calculated area of ​​the flame (13) to control the width of the discharge port for discharging the fire extinguishing liquid.

[0062] The control unit (105) has a preset discharge port width for the extinguishing liquid determined according to the area of ​​the calculated flame (13), and drives the first motor (126a) and the second motor (128a) to rotate the first variable pipe (125) and the second variable pipe (127) simultaneously to adjust the discharge port width for extinguishing liquid.

[0063] The control unit (105) adjusts the width of the discharge port for discharging the extinguishing liquid so that, depending on the area of ​​the flame (13), the spray of the extinguishing liquid may form a straight line shape, or the first variable pipe (125) and the second variable pipe (127) may spread out toward the discharge port and spray radially.

[0064] Additionally, the fire suppression device (110) is connected to the management server (200) via wireless or wired communication.

[0065] Since the fire suppression device (110) is installed in each household, it is connected to a management server (200) so that it can be managed with a management number assigned to each household, so the management server (200) can control each fire suppression device (110) individually according to the fire detection signal.

[0066] In particular, the above-mentioned management server (200) performs various signal processing, such as signal processing for fire detection, signal processing for device control, and signal processing for database management, through a plurality of processing modules, and these processing modules are installed in a server housing (300) as shown in FIG. 7.

[0067] At this time, the server housing (300) is characterized by having an eco-friendly natural cooling structure to prevent heat generation, deterioration due to dust, and short circuits of the installed processing modules.

[0068] To this end, the server housing (300) includes a front door (DR), and a housing controller (310) is installed on the front door (DR). A ventilation hole (H) communicating with the interior is formed on the lower side of the front door (DR) at a distance from the housing controller (310), and the ventilation hole (H) is configured to be filtered by a filter cloth (320). A plurality of exhaust holes (D) are formed on the upper surface of the server housing (300), and the exhaust holes (D) are covered by an exhaust fan (330) to allow air inside the server housing (300) to be discharged to the outside.

[0069] Additionally, a fine dust detector (340) and a temperature sensor (350) are installed inside the server housing (300), and are configured to be electrically connected to the housing controller (310) to transmit detection information to the housing controller (310).

[0070] Thus, when the fine dust inside the server enclosure (300) exceeds the set value, the enclosure controller (310) immediately activates the exhaust fan (330) to discharge the internal air to the outside, thereby lowering the fine dust concentration.

[0071] In addition, a space cut to a certain size is formed on the rear of the server housing (300), and a plate heat exchanger (360) is fitted into this space and fixed by adhesive in an overlay form.

[0072] In this case, the plate heat exchanger (360) is formed with two different independent flow paths inside, and internal air circulation openings (362) are formed on the upper and lower sides facing the inside of the server housing (300).

[0073] The above internal air circulation port (362) is in a form where internal air enters through one of the two sides and is discharged through the other side, and circulates in a convection form that occurs naturally depending on the temperature of the internal air.

[0074] Additionally, external air circulation ports (364a, 364b) are formed on the upper and lower plates of the plate heat exchanger (360) facing the outside of the server housing (300) so that external air, particularly cooling air, can be forcibly supplied.

[0075] To this end, an external air circulation port (364a) on the upper side is provided with a supply pipe (P1) connected to a blower (BR), and a solenoid valve (S) is installed on the supply pipe (P1) and is controlled to open and close by the housing controller (310).

[0076] In addition, an exhaust pipe (P2) is installed in the lower external air circulation port (364b) so that the heat-exchanged cooling air can be naturally discharged to the outside.

[0077] In addition, it is preferable that a part of the supply pipe (P1) be immersed in a cooling water tank (WT) so that the external air discharged from the blower (BR) maintains a cooling state.

[0078] Then, as the outside air passes through the supply pipe (P1) submerged in the cooling water tank (WT), it undergoes heat exchange and can be supplied in an even colder state.

[0079] Thus, when the internal temperature detected by the temperature sensor (350) exceeds the specified value, the enclosure controller (310) opens the solenoid valve (S) and simultaneously activates the blower (BR). As the cooling air passes through the plate heat exchanger (360), it exchanges heat with the internal air circulating through another path to cool it, so the internal air is naturally cooled. Since it is cooled without generating dust or introducing external air, the cooling efficiency is improved.

[0080] Additionally, a cooling jacket (CH) is further installed on the outer surface of the plate heat exchanger (360), and water can be filled into the cooling jacket (CH). Then, the cooling performance can be further improved.

[0081] Here, since the adhesive must ensure strong adhesion, prevention of interfacial separation, water resistance, heat resistance, and chemical resistance without easily peeling off, it is prepared by mixing 5.5 parts by weight of sodium erythorbate, 10 parts by weight of benzoic acid vinyl ester, 8.5 parts by weight of sodium laureth-6 carboxylate, 10 parts by weight of polyvinyl butyral, 10 parts by weight of isooctyl glucoside, and 8 parts by weight of trimellitic anhydride with respect to 100 parts by weight of polyimide.

[0082] At this time, sodium erythorbate increases surface oxidation resistance and photothermal resistance, and increases discoloration resistance and erosion resistance against ultraviolet rays.

[0083] In addition, benzoic acid vinyl ester is a substance corresponding to CAS number 769-78-8 that increases UV resistance, thereby suppressing surface cracking and detachment of the adhesive and contributing to strengthening the adhesive strength.

[0084] In addition, sodium laureth-6 carboxylate reduces moisture content and decreases porosity, thereby enhancing water resistance, durability, and corrosion resistance.

[0085] In addition, polyvinyl butyral is a material corresponding to CAS number 63148-65-2, which contributes to ensuring chemical resistance and flexibility, inhibiting oxidation, and enhancing water resistance.

[0086] In addition, Isooctyl Glucoside is a substance corresponding to CAS No. 125590-73-0, and when combined, it decomposes and removes oil from the mixture, thereby inducing surface homogenization and contributing to the enhancement of adhesion and bonding strength.

[0087] In addition, trimellitic anhydride has the property of inhibiting cracking and even improving waterproofing.

[0088] On the other hand, the above-mentioned management server (200) is further connected to a danger zone monitor (210) that is installed in a blind spot of a multi-unit dwelling and performs a monitoring function, as shown in the example of FIG. 8.

[0089] At this time, the danger area monitor (210) includes a built-in monitoring control unit (212), a CCD camera (214) that photographs a blind area in real time according to a control signal from the monitoring control unit (212), a flame detector (216) installed at a location adjacent to the CCD camera (214) that detects whether a fire has occurred in the blind area by a flame and outputs a detection signal to the monitoring control unit (212), and an alarm (218) connected to the monitoring control unit (212) that broadcasts a warning when unidentified persons, including delinquent youths, gather.

[0090] Here, blind spots are secluded areas of apartment buildings, which can mainly be shelters, smoking areas, or secluded places between buildings.
