Description

[Technical field]

[0001] The present invention relates to a fire extinguishing device capable of effectively extinguishing a fire occurring in a material or waste dump. [Background technology]

[0002] For example, at a building demolition site, temporary storage areas for materials and industrial waste such as containers are set up, and as fires may break out from these, they are also subject to fire prevention measures. As an example of such a fire extinguishing device for a temporarily installed fire prevention target, there is an arson detection system disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-303093 A Summary of the Invention [Problem to be solved by the invention]

[0004] The system disclosed in Patent Document 1 sends an arson signal to a mobile terminal in the event of arson or other such incident in an unmanned material storage area, but does not disclose a method for extinguishing a fire that has occurred. Although various fire extinguishing methods are known, there are special circumstances in material storage areas and industrial waste storage areas, as described below. These special circumstances will be explained using an industrial waste container as an example.

[0005] Industrial waste containers are used to temporarily store industrial waste before it is transported by vehicle to an industrial waste site. Industrial waste includes various combustible materials such as interior materials and insulation materials, which may cause a fire. If a fire breaks out inside a waste container, it may not be possible to pour water directly on the burning object because of the piled up garbage. In addition, if the container has a bottom and walls, such as an industrial waste container, it may be possible to submerge it in water, but there is a risk that some flammable materials will float on the water and be washed away.

[0006] In addition, waste is generally piled higher than the walls of the industrial waste container, so it cannot be covered with foam. Although foam extinguishing is possible by surrounding the industrial waste container with a partition to block the foam, such a partition would get in the way when disposing of waste in the industrial waste container and when collecting it, so this is not a practical method.

[0007] The present invention has been made to solve the above problems, and has an object to provide a fire extinguishing device that can effectively extinguish fires that occur in material storage areas or industrial waste storage areas. [Means for solving the problem]

[0008] (1) A fire extinguishing device according to the present invention comprises at least three guide members erected to surround a material or waste storage area, a fire-resistant cloth capable of covering the material or waste storage area, a holding mechanism for holding the fire-resistant cloth on an upper portion of the guide members, and a fire detector for detecting a fire occurring in the material or waste storage area; the holding mechanism has a holding / releasing function that releases the holding of the fire-resistant cloth from the guide member upon receiving a detection signal from the fire detector, When the fire-resistant cloth is released from the guide member, it falls, guided by the guide member, to cover the material or waste storage area.

[0009] (2) In the above (1), the fireproof cloth is arranged to have an inclined surface, The fire detector is characterized in that it is disposed at a high position on the inclined surface of the fire-resistant cloth.

[0010] (3) Furthermore, in the above-mentioned (1) or (2), the fire-resistant cloth has a hanging portion that hangs down around its periphery when in the held state, making it difficult for smoke and / or heat from a fire to escape to the outside of the fire-resistant cloth.

[0011] (4) Furthermore, in any one of the above (1) to (3), the material or waste storage area is characterized in that it is surrounded by a peripheral wall. Effect of the Invention

[0012] In the fire extinguishing device of the present invention, upon receiving a detection signal from a fire detector, the guide member releases the fire-resistant cloth, and the fire-resistant cloth is guided by the guide member and falls to cover the materials or waste storage area, thereby enabling effective fire extinguishing even in cases where it is difficult to extinguish a fire with water or foam. In addition, compared to extinguishing fires with water or foam, recovery after activation is easier, and it has the added advantage of having absolutely no impact on materials or the surrounding area in the event of a malfunction. Furthermore, since no water source or extinguishing agent tank is required, the equipment is simple and easy to install. [Brief description of the drawings]

[Diagram 3] FIG. 4 is a front view of another aspect of the fire extinguishing apparatus according to the embodiment of the present invention. [Figure 4] FIG. 4 is a right side view of the fire extinguisher shown in FIG. 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] As shown in Figures 1 and 2, the fire extinguishing device 1 of this embodiment is equipped with four guide members 5 erected to surround an industrial waste container 3 serving as a waste disposal site, a fire-resistant cloth 7 that can cover the industrial waste container 3, a holding mechanism 9 provided on the upper part of each guide member 5 to hold the fire-resistant cloth 7 on the upper part of the guide member 5, and a fire detector 11 that detects a fire that breaks out in the industrial waste container 3. Each component will be described in detail below.

[0015] <Industrial waste container> The industrial waste container 3 is an example of a waste dump of the present invention, and is used to temporarily store industrial waste before it is transported by car to the industrial waste site. The industrial waste is temporarily stored in the industrial waste container 3 and then transported by car to the industrial waste site. As shown in Figure 1, the industrial waste container 3 is made of a rectangular frame with a bottom and a perimeter wall and a bottom.

[0016] <Fireproof cloth> The fireproof cloth 7 has an area large enough to cover the industrial waste container 3, and in the event of a fire, it drops onto the industrial waste container 3 to cover it and extinguish the fire by suffocating it. The fire-resistant cloth 7 of this embodiment is rectangular and must be kept open when dropped, so it has rod-shaped rib members 13 extending from left to right on the front and back sides. The rib members 13 are disposed in front of the left and right guide members 5 on the front side shown in Fig. 1, and disposed behind the guide members 5 on the back side.

[0017] The material of the fire-resistant cloth 7 is not particularly limited as long as it can be placed over the source of a fire to smother and extinguish the fire. For example, high-purity silica cloth may be used.

[0018] As shown in FIG. 1, the fire-resistant cloth 7 of this embodiment is installed in an inclined state so that the right side is higher when viewed from the front. By installing the fire-resistant cloth 7 at an angle, it is possible to prevent rainwater from accumulating. In addition, the fire-resistant cloth 7 has a function of guiding hot air currents containing smoke generated in the event of a fire to the fire detector 11. In relation to this function, as shown in Fig. 1, by disposing the fire detector 11 at a high position on the fire-resistant cloth 7 installed at an angle, the smoke / heat guiding function can be more effectively exerted.

[0019] 1 and 2, the fire-resistant cloth 7 preferably has a hanging portion 15 that hangs down around its periphery when it is held by the guide member 5. The provision of the hanging portion 15 makes it difficult for smoke and heat from a fire to escape to the outside of the fire-resistant cloth 7, so that the smoke / heat guide function can be more effectively exerted. In this embodiment, hanging portions 15 are provided on two of the four sides of the fire-resistant cloth 7, namely, the front side and the back side in FIG.

[0020] <Guide parts> The guide members 5 are four pillar-shaped members erected to surround the industrial waste container 3. The guide members 5 have the function of holding the fireproof cloth 7 above the industrial waste container 3 and the function of guiding the fireproof cloth 7 when it falls. In order to achieve such a function, the number of guide members 5 needs to be at least three, and the shape thereof is not particularly limited, and is not limited to the columnar member of this embodiment. A stopper 16 may be provided at the bottom of the guide member 5 to control the lowest position of the fire-resistant cloth 7 when it falls.

[0021] <Retention mechanism> The holding mechanism 9 holds the fire-resistant cloth 7 on the top of the guide member 5 under normal circumstances, and has a holding / release function that releases the hold of the fire-resistant cloth 7 on the guide member 5 in the event of a fire upon receiving a detection signal from a fire detector 11.

[0022] One example of a retaining mechanism 9 is one that includes a convex piece 17 that is attached to a frame member 13 of the fire-resistant cloth 7 and that protrudes and retracts so that it can be inserted and removed from a locking hole (not shown) provided in the upper part of the guide member 5, as shown in Figure 1, a solenoid 19 that operates the convex piece 17, and a control unit 21 that receives a signal from the fire detector 11 and controls the solenoid 19.

[0023] <Fire detector> The fire detector 11 is a smoke or heat type fire detector that detects a fire by a hot air current containing smoke generated in the event of a fire and transmits a detection signal to the control unit 21. The fire detector 11 is disposed adjacent to the underside of the fire-resistant cloth 7 via a mounting member 23 at a high position on the slope of the fire-resistant cloth 7. The form of the fire detector of the present invention is not particularly limited, and in addition to a general fire detector, it may be a special type adapted to outdoor or dusty environments.

[0024] The operation and effect of the fire extinguisher 1 of the present embodiment configured as above will be described. 1, the industrial waste container 3 is normally placed below the approximate center of the fireproof cloth 7. Therefore, even if it rains, the fireproof cloth 7 acts as a roof, preventing the industrial waste from getting wet with rainwater and preventing water from accumulating inside the industrial waste container 3.

[0025] When a fire breaks out inside the industrial waste container 3, the hot air current containing smoke is guided by the fire-resistant cloth 7 to the higher side of the incline. When the hot air current reaches the fire detector 11 and the fire detector 11 detects a fire, a detection signal is sent to the control unit 21, which then operates the solenoid 19. When the solenoid 19 is operated, the protruding piece 17 comes out of the locking hole and the lock is released. As a result, the fire-resistant cloth 7 falls while being guided by the guide member 5, covering the industrial waste container 3 and extinguishing the fire by suffocation.

[0026] As described above, the fire extinguisher 1 of the present embodiment can effectively extinguish a fire even in cases where it is difficult to extinguish the fire with water or foam. In addition, in this embodiment, the fire-resistant cloth 7 is installed at an angle and has a hanging portion 15, so that the hot air current containing smoke can be effectively guided to the fire detector 11 without escaping, making it possible to extinguish a fire in its early stages. In addition, compared to extinguishing fires with water or foam, recovery after activation is easier, and it has the added advantage of having no impact on materials or the surrounding area, particularly in the event of a malfunction. Furthermore, since no water source or extinguishing agent tank is required, the equipment is simple and easy to install.

[0027] In the above embodiment, the fire-resistant cloth 7 is installed at an angle, but the invention is not limited to this, and the fire-resistant cloth 7 may be installed horizontally as shown in Figures 3 and 4. In this case, hanging parts 15 are provided on the four sides of the fire-resistant cloth 7, and the fire detector 11 is installed in the center of the fire-resistant cloth 7, as shown in Figures 3 and 4.

[0028] In addition, in the above embodiment, rib members 13 are provided on the opposite edges of the fire-resistant cloth 7 at the front and back when viewed from the front, and the rib members 13 are guided by the guide members 5 to fall, but it is also possible to provide rings at the four corners of the fire-resistant cloth 7, for example, and insert the rings into the four guide members 5.

[0029] In addition, in the above embodiment, an industrial waste container 3 is used as an example of a waste disposal site, but the waste disposal site of the present invention is not limited to the industrial waste container 3, and also includes a waste disposal site on the ground with a surrounding wall that acts as an enclosure, or a waste disposal site that is simply on the ground with no enclosure. Furthermore, the application of the present invention is not limited to waste dump sites, but is also applicable to material dump sites at construction sites and the like. [Explanation of symbols]
