Description

[Technical Field]

[0001] The present invention relates to a fire extinguishing apparatus used for electrical equipment such as switchboards and distribution boards. [Background Art]

[0002] Switchboards and distribution boards installed as electrical equipment in residences, factories, automobiles and the like have a risk of fire caused by poor contact, deterioration of capacitors, inadequate wiring work and other factors. Hereinafter, the term "switchboard" includes the meaning of distribution board.

[0003] Fires caused by ignition in switchboards are caused by overload, short circuit, aging deterioration and other factors, and there are many cases where initial detection and fire extinguishing are difficult. In particular, it is difficult to use water or powder fire extinguishing agents for electrical equipment, and there are also concerns about the risk of secondary damage.

[0004] Among conventional fire extinguishers, powder-based fire extinguishers are generally known to eject white powder, but when used on burning articles or equipment, the white powder ejected from the nozzle settles on and stubbornly adheres to the articles or equipment, making it difficult to remove the white powder during post-extinguishing post-treatment. If the white powder is sucked with a vacuum cleaner, it penetrates the filter, causing problems such as malfunction of the vacuum cleaner, which also adversely affects post-treatment after fire extinguishing work, resulting in difficult handling and inconvenience. [Prior Art Documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2012-55360 [Patent Document 2] Japanese Unexamined Patent Application Publication No. 2004-135742 [Patent Document 3] Japanese Unexamined Patent Application Publication No. 2024-153532 [Patent Document 4] Japanese Patent No. 7469507 [Summary of the Invention] [Problem to be Solved by the Invention]

[0006] Commonly available fire extinguishers are heavy, weighing, for example, 5 kg. Because of their weight, these types of fire extinguishers are inconvenient to handle. It is difficult to manually lift heavy fire extinguishers to high places or to maneuver them into confined spaces. Therefore, if a fire occurs at a high place or in a confined space, it may be impossible to perform the desired firefighting operation.

[0007] Patent Document 1 discloses a fire extinguisher that contains a fire extinguishing liquid inside a so-called vertically elongated container, and uses ordinary water, distilled water, or pure water as the fire extinguishing liquid. Therefore, it has been difficult to make the weight of the fire extinguisher body, which contains a certain amount of fire extinguishing liquid required for fire extinguishing, lighter. Furthermore, it is difficult to grasp such a heavy fire extinguisher body with one hand, and if the container is supported with one hand and the nozzle is manually operated with the other hand, it becomes difficult to handle (inconvenient to operate).

[0008] Furthermore, Patent Document 2 discloses a fire extinguisher in which the nozzle is oriented perpendicular to the longitudinal direction of the container. Because the container is placed vertically when not in use and the mist nozzle is positioned perpendicular to the direction of gravity of the vertically oriented container, the operability, which is a criterion for evaluating usability, is poor. Generally, there is a strong demand to complete initial fire suppression (extinguishing the fire within two minutes) when a fire breaks out. Achieving initial fire suppression can significantly reduce the damage and losses caused by fire. Therefore, providing means to achieve initial fire suppression has become a top priority issue that society demands.

[0009] Traditionally, standard fire extinguishers include powder-based, water-based, and gas-based extinguishers. In most cases, all of these fire extinguishers consist of a large-diameter cylindrical container placed vertically on the floor, with a nozzle attached to the outside of the top of the container, or a hose extending from the side of the container with the nozzle at the end of the hose attached to the outer wall of the top of the container. Patent document 3 proposes an automatic fire extinguishing system that employs a laminated structure containing two fire extinguishing agent layers with different compositions. Patent document 4 also proposes a fire extinguishing body for objects to be extinguished, such as power distribution boards and switchboards.

[0010] Patent documents 1, 2, 3, and 4 all disclose fire extinguishing bodies or devices to be placed near objects to be extinguished; however, they do not disclose any technical ideas that take into account maintenance, including replacement of fire extinguishing bodies, etc., when they deteriorate.

[0011] This invention has been made in view of the above-mentioned problems, and its purpose is to provide an automatic fire extinguishing device that detects indoor fires in their initial stages and automatically extinguishes them. [Means for solving the problem]

[0012] The fire extinguishing device of the present invention is a fire extinguishing device (20) for a distribution panel that extinguishes a fire occurring in a room housing a distribution panel, A holder (50) capable of holding a fire extinguishing stick (1) can be attached to partition plates (41, 43, 44) that define a room (40) housing a distribution board (21, etc.), The system includes a movable member (54) for detachably attaching the fire extinguishing stick to the holder, When the fire extinguishing stick is attached to the holder by the movable member, the configuration is such that the ignition portion (7) at one end of the fire extinguishing stick is exposed to the chamber, and the other end of the fire extinguishing stick is exposed to the outside of the chamber.

[0013] According to the fire extinguishing device for power distribution panels of the present invention, it does not use electrical energy, is power-free, and uses a slim fire extinguishing stick, so it requires a small installation space and is easy to install. It can automatically extinguish a fire without human intervention in the initial stages of a fire.

[0014] By using a slim fire extinguishing stick to spray inert gas instead of powder or water-based fire extinguishers, the burden of post-fire cleanup, such as cleaning up after a fire in a room containing an electrical panel, can be significantly reduced, eliminating the need for manual labor. Since fire is extinguished by reducing the oxygen concentration through the release of inert gas ejected from the fire extinguishing stick, damage to surrounding equipment can be minimized.

[0015] The fire extinguishing device can be retrofitted to an existing room where a switchboard is installed, and the installation work of the lightweight and compact fire extinguishing stick can be easily performed. After the device is installed, maintenance management such as inspection and replacement of the fire extinguishing stick can be easily performed. It is effective as a new switchboard fire countermeasure that combines safety and efficiency while reducing the risk of switchboard fire. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Hereinafter, a fire extinguishing device according to an embodiment of the present invention will be described with reference to the drawings. In a plurality of embodiments, substantially identical constituent parts are denoted by the same reference numerals, and descriptions thereof are omitted.

[0018] (One Embodiment) An embodiment of a fire extinguishing device applied to a room accommodating a switchboard will be described with reference to Figs. 1 to 6. (Configuration of Fire Extinguishing Stick) Fig. 1 shows an example of a fire extinguishing stick used in a fire extinguishing device for a switchboard. Fig. 2 is a plan view of a ceiling plate corresponding to a partition plate that partitions a room accommodating a switchboard. A fire extinguishing stick is a lightweight, compact, and slender tool used to extinguish fires, serving as an alternative to conventional fire extinguishers.

[0019] The fire extinguishing stick 1 comprises a cylindrical metal body 3, an ignition part 7 consisting of an igniter installed at the tip of the body 3, a handle 5 integrally connected coaxially to one end of the body 3 on the opposite end, and an end cap 6 that can be detachably attached to the ignition part 7 from the tip side of the body 3 and to one end of the handle 5 on the opposite end.

[0020] The cartridge (not shown) housed in the main unit 3 contains a fire extinguishing agent. The ignition unit 7 is equipped with an igniter that ignites when it reaches a predetermined temperature. This ignition unit 7 corresponds to an ignition unit that ignites when it detects a factor that causes ignition. The handle 5 has a hollow cylindrical section 15, with one end having an opening 8 and the other end connected to the base end of the main body 3, and is grippable by the user.

[0021] The end cap 6 is detachably provided so as to be able to close the opening 8 of the hollow cylindrical portion 15. When the end cap 6 is attached to the hollow cylindrical portion 15, the end cap body 9 is fitted into the opening 8, causing the outer wall of the body 9 and the inner wall of the hollow cylindrical portion 15 to slide against each other. The end cap body (not shown) of the end cap gripping portion 12 comes into contact with the opening 8, is positioned, and the outer wall of the end cap body and the inner wall of the hollow cylindrical portion 15 are joined with a sense of decisiveness. When removing the end cap 6, the end cap gripping portion 12 can be held and pulled out from the opening 8 to remove the end cap 6 from the hollow cylindrical portion 15.

[0022] (Configuration of the power distribution room) Figure 2 shows one embodiment of a fire extinguishing system for a power distribution panel, in which a room 40 (power distribution room) housing the power distribution panel is partitioned by a partition plate. Figure 2 shows the front door in the open position.

[0023] The fire extinguishing device 20 for the power distribution panel has a fire extinguishing stick 1 attached to the approximate center of a ceiling panel 41, which is equivalent to a partition plate that makes up the ceiling of a room 40 that houses a large number of various power distribution panels (including distribution boards, collectively referred to as power distribution panels) 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, and 33.

[0024] Numerous electrical wires, including multiple electrical wirings 34, 35, and 36, are installed inside room 40. The electrical wires are inserted into the room 40 from outside the ceiling panel 41. The room 40 is partitioned by a ceiling panel 41, a bottom panel 42, side panels 43 and 44 that form the left and right side walls, a front door panel 45, and a rear panel 46. The state shown in Figure 2 is with the front door open, but when the front door panel 45 is closed, the room 40 becomes a space enclosed by the partition panel. The ceiling panel 41, the bottom panel 42, the side panels 43 and 44 that form the left and right side walls, the front door panel 45, and the rear panel 46 correspond to the partition panel in the claims.

[0025] (Holder configuration and equipment) As shown in Figures 3, 4, and 5, the holder 50 is fixed to the approximate center of the upper surface of the ceiling panel 41 by fixing screws 53. The holder 50 consists of a cylinder 51 and a flange 52. The flange 52 has a predetermined thickness, extends radially outward from the lower end of the cylinder 51, and has a circular outer wall.

[0026] The cylinder 51 is a cylindrical body with an outer wall diameter smaller than the outer diameter of the flange 52. The lower end surface of the cylinder 51 is joined to the upper surface of the ceiling plate 41 together with the lower surface of the flange 52. The upper surface of the flange 52 is secured to the ceiling panel 41 by fixing screws 53 at three points. This secures the holder 50 to the ceiling panel 41. The cylinder 51 has a screw hole 55 formed on its side, and the screw head 541 of the tightening screw 54, which corresponds to a movable member, is turned to clamp the hollow cylindrical part 15, which corresponds to the handle 5 of the fire extinguishing stick 1 (not shown in Figure 5), between the inner wall 511 of the cylinder 51 and the screw tip (not shown) of the tightening screw 54, thereby fixing the fire extinguishing stick 1 to the holder 50.

[0027] When installing or replacing the fire extinguishing stick, the fixing of the fire extinguishing stick can be released by loosening the tightening screw 54. After releasing the fixing and replacing it with a new fire extinguishing stick, the tightening screw 54 can be tightened to replace the fire extinguishing stick with a new one. For example, by regularly replacing the fire extinguishing stick with a new one, the function of the fire extinguishing device 20 for the distribution board can be maintained at all times. This makes it possible to maintain the function of an automatic fire extinguishing device that can operate without power through a simple replacement procedure.

[0028] When the front door panel is closed, the moment of ignition cannot be visually observed if a fire breaks out inside the room. However, as shown in Figure 6, a flame 37, which is one example of a factor that can be detected as a fire, is generated. Instantly, the ignition part 7 of the fire extinguishing stick reacts, and the fire extinguishing stick 1 is activated. Then, inert gas 38 is sprayed from the nozzle of the fire extinguishing stick 1, creating an oxygen-free environment by spraying the inert gas. By maintaining this oxygen-free environment for a certain period of time, the fire is extinguished. Because firefighting is completed unmanned, it has a high probability of minimizing losses caused by fire after it has started.

[0029] Without requiring a power source, fires in electrical distribution panels can be extinguished automatically and unattended. Furthermore, because it uses a fire extinguishing stick that sprays inert gas instead of the conventional powder-based or water-based fire extinguishers that have been widely used, it has the effect of reducing the burden of post-fire cleanup, such as eliminating the need for human labor to clean up after extinguishing a fire inside an electrical panel.

[0030] (Comparison with comparative forms) The comparative form refers to a fire extinguishing device installed in a room containing a distribution panel, in case the distribution panel catches fire. The fire extinguishing devices used in the comparative configuration utilize large-diameter cylindrical metal containers and are heavy objects, for example, weighing 5 kg. These types of heavy fire extinguishers are typically placed on the floor outside the room housing the electrical panel. There is no custom of installing these heavy fire extinguishers on the partition plates separating the room housing the electrical panel, nor is it structurally unsuitable. The idea of ​​applying the holder of the present invention to these types of heavy fire extinguishers would not arise.

[0031] As mentioned above, the comparative type of fire extinguisher is usually placed on the floor outside, so it does not directly detect fires inside the room. With the front door closed inside the room, fire cannot be detected visually. Unattended firefighting is impossible, as firefighting activities must begin with manual operation of the fire extinguisher.

[0032] In contrast, the fire extinguishing device for electrical distribution boards of this embodiment uses a lightweight fire extinguishing stick, for example, weighing 365g. The holder of this embodiment is applied to fire extinguishing sticks that are significantly smaller, lighter, and offer superior operability and convenience compared to conventional fire extinguishers of comparative form.

[0033] As described above, the fire extinguishing device for electrical distribution boards of this embodiment can be attached to the ceiling panel with simple operation using a lightweight and easy-to-operate fire extinguishing stick. Therefore, the advantages of the fire extinguishing stick, such as convenience, ease of operation, and lightweight / compact size, can be further enhanced. Consequently, the possibility of achieving initial fire suppression can be greatly improved.

[0034] (Regarding the action of fire extinguisher sticks) An example of the operation of the fire extinguishing stick of this embodiment will be described. If a fire breaks out in an electrical panel or other equipment inside the room, the flames will cause the room temperature to rise. When the room temperature rises above a predetermined level or when flames are detected, the ignition unit reacts and the fire extinguishing stick activates.

[0035] When the ignition agent in the main unit 3 is ignited, the components inside the cartridge undergo a chemical reaction, and the extinguishing agent is sprayed from the tip of the main unit 3. Specifically, potassium nitrate and dicyandiamide burn through a chemical reaction, and an inert gas containing white, vapor-like potassium particles is sprayed out. The large amount of potassium radicals depletes the oxygen inside and around the flame, creating a suffocating and suppressive effect that interrupts the combustion chain.

[0036] (Comparison of a fire extinguisher stick with a fire extinguisher) This explanation will compare Fire Extinguishing Stick 1 with a standard fire extinguisher (powder fire extinguisher).

[0037] (1) Spray duration: The fire extinguishing stick can spray continuously for up to 100 seconds, for example. Generally, the first two minutes after a fire starts are called the initial fire extinguishing period, and this has a remarkable effect in achieving initial fire extinguishing. (2) Weight: The fire extinguishing stick (excluding accessories) is lightweight at 365g. Therefore, it is easy to carry in the event of a fire. (3) Residues: Because the fire extinguishing stick sprays an inert gas, no harmful residues are left behind. Therefore, it is easy to restore items and equipment at the site of the fire after it has been extinguished. (4) The fire extinguishing stick can also be used to deal with flammable gas fires that cannot be handled by ordinary fire extinguishers.

[0038] (5) Expiration date: The expiration date for fire extinguishing sticks is 15 years, which is longer than that of general fire extinguishers. (6) Durability: Because the fire extinguishing stick is non-pressurized, it has excellent durability and impact resistance. (7) Periodic inspection: Fire extinguishing sticks do not require periodic inspection by a legally qualified person. (8) Safety and Environment: The fire extinguishing stick uses an inert gas as its propellant. Therefore, it does not adversely affect the breathing or vision of the operator or those nearby, and does not contribute to global warming or ozone layer depletion.

[0039] For reference, the specifications of conventional fire extinguishers are as follows: (1) Spray duration: Conventional fire extinguishers have a spray duration of, for example, about 15 seconds. This often fails to achieve initial fire suppression. (2) Weight: Conventional fire extinguishers are generally heavy, with most weighing around 5 kg. This makes them difficult to carry during a fire. (3) Residues: Standard fire extinguishers leave behind chemical residue and stains after spraying. This makes it difficult to restore items and equipment in the affected area after the fire has been extinguished. (4) Conventional fire extinguishers cannot handle flammable gas fires. (5) Expiry date: Conventional fire extinguishers deteriorate quickly and have a short shelf life. (6) Durability: Conventional fire extinguishers are pressurized, so they have poor durability and impact resistance. (7) Periodic inspections: Conventional fire extinguishers require periodic inspections by legally qualified personnel, and their handling is complicated.

[0040] According to this embodiment, when a fire occurs, a chemical reaction can be used to instantly automate the entire process, from extinguishing the fire to its conclusion without the need for a power source. Moreover, post-fire cleanup is virtually unnecessary, significantly reducing the burden of post-fire cleanup. Furthermore, from a safety and environmental perspective, conventional fire extinguishers tend to affect the breathing and vision of the operator and those around them, and contribute to global warming and ozone layer depletion. However, according to this embodiment, the fire extinguishing device using a fire extinguishing stick has the advantage of not causing such adverse effects in terms of safety and the environment.

[0041] According to this embodiment, maintenance can be easily performed by periodically replacing the fire extinguishing stick with a new one by moving the tightening screw 54, for example, every 5 years or irregularly. According to this embodiment, the other end of the fire extinguishing stick is exposed to the outside, allowing the fire extinguishing stick to be visually inspected from outside the room. Furthermore, during maintenance of the device, the fire extinguishing stick can be easily replaced from outside the partition plate by tightening and loosening the fastening screws.

[0042] (Operation of the Embodiment of the Present Invention) According to this embodiment, if a fire occurs in a room where a power distribution panel or the like is installed, the ignition part of the fire extinguishing stick automatically ignites, spraying inert gas to suppress flying embers and speed up fire extinguishing. Furthermore, by igniting the ignition part due to the temperature rise caused by the fire in the room housing the power distribution panel or the like, and continuing to spray inert gas for, for example, 100 seconds, complete fire extinguishing can be achieved.

[0043] (Other embodiments) The above embodiment was an example in which the holder was applied to the ceiling panel 41, but the present invention can also be applied to side panels (43, 44) corresponding to partition panels that extend in the direction of gravity. In other embodiments applied to the side panel, back panel (46), or front door panel (45), the fire extinguishing stick has its longest side facing horizontally, so when a fire is detected in the room, it sprays inert gas horizontally into the room from the ignition part.

[0044] In another embodiment, when a room (40) is constructed above the floor surface, the holder can be attached to a bottom plate (42) which corresponds to a partition plate.

[0045] In this invention, when a fire extinguishing stick is mounted on a partition plate via a holder, the inclination angle of the axial center of the fire extinguishing stick is not specified, but can be set to any angle. This invention allows the holder to be attached to any partition plate that divides a room. The form of the holder of the present invention is not limited to the form of the embodiment described above, and its shape and size are not limited as long as it can be fixed to the partition plate. Furthermore, the mechanism for attaching and detaching the holder and the fire extinguishing stick using a movable member may also be a mechanism other than that of the embodiment described above.

[0046] Although the above embodiment describes an embodiment applied to a room housing a power distribution panel, it goes without saying that the present invention can also be applied to a room housing equipment other than a power distribution panel, such as a battery power supply. The present invention can also be applied to rooms containing electrical equipment for automobiles, such as switchboards and battery power supplies, which are targets for fire suppression.

[0047] For example, when a camper van is equipped with fire extinguishing devices such as cooking equipment, boilers / propane tanks, heating systems, and engines, the present invention can be applied to partition plates or equivalent components that define the compartments containing these fire extinguishing devices. If these fire extinguishing devices catch fire, the fire extinguishing stick will automatically activate upon detecting the fire, and shortly after ignition, the fire extinguishing stick will automatically spray inert gas, extinguishing the fire source in the compartment. This prevents losses caused by fire and minimizes damage.

[0048] This invention can be applied not only to fire extinguishing devices for power distribution boards and switchboards, but also to fire extinguishing devices that occur in rooms housing electrical equipment. According to the present invention, unmanned firefighting can be quickly achieved for objects after a fire has broken out, enabling initial fire suppression and avoiding significant losses. According to the present invention, since a smaller and slimmer fire extinguishing stick is used than that of generally known fire extinguishers, the device can be installed in a space-saving manner without restricting the installation space for equipment on objects to be extinguished, such as electrical distribution boards.

[0049] According to the present invention, this fire extinguishing device can be easily retrofitted to a room containing an object to be extinguished, and it has the effect of detecting the occurrence of a fire in the object to be extinguished without human intervention, operating without power supply when a fire occurs, and automating the fire extinguishing process. Regarding the maintenance of the fire extinguishing device of the present invention, the work of replacing an old fire extinguishing stick with a new one can be easily performed by operating a movable member periodically or irregularly.

[0050] Furthermore, the fire extinguishing stick to which the present invention is applied is not limited to that of the embodiments described above. For example, a fire extinguishing stick that can use the holder of the present invention will spray a gas, liquid, or powder with fire extinguishing properties from one end, and will not cause any damage to electrical panels or other components inside a room, or will not cause significant damage, and even if damage to an electrical panel occurs, the damage will be kept to a minimum. As stated above, the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from its essence. The fire extinguishing device for a power distribution panel of the present invention may be configured such that the ignition unit ignites when it detects a factor that causes ignition in the chamber (40). The factor that causes ignition may be a predetermined temperature or a flame.

[0051] The fire extinguishing device for a power distribution panel of the present invention may be configured such that the holder and the movable member are a cylinder (51) having a screw hole (55) and a screw (54) that can be screw-rotated into the screw hole. The fire extinguishing device for a power distribution board of the present invention may be configured such that the fire extinguishing stick comprises a cylindrical body (3), an ignition part consisting of an igniter installed at the tip of the body, and a hollow cylindrical part (15) integrally connected coaxially to the opposite end of the body.

[0052] The present invention may use a battery power source instead of the aforementioned distribution board. The present invention can also be applied to a fire extinguishing system powered by a battery. The present invention may use other electrical components or electrical equipment instead of the aforementioned switchboard. The present invention can be applied to both fire extinguishing devices for electrical components and fire extinguishing devices for electrical equipment. The fire extinguishing device of the present invention can be applied not only to rooms inside and outside buildings on the ground, but also to rooms housing switchboards, electrical components, or electrical equipment installed in automobiles, ships, etc. The present invention may apply to the object to be extinguished instead of the distribution board. The present invention can also be applied to fire extinguishing systems for objects to be extinguished. In the description of this invention, the term "distribution board" is a concept included in the concepts of electrical components, electrical equipment, and objects to be extinguished by fire, and the term "distribution board" corresponds to the meaning of electrical components, electrical equipment, and objects to be extinguished by fire.
