Disclosure of Invention
Problems to be solved by the invention
However, it is not easy for an operator to accurately spray the fire extinguishing agent toward the fire source due to unfamiliarity with the fire extinguisher, or the sprayed fire extinguishing agent widely scatters and sufficient fire extinguishing efficiency cannot be obtained, or secondary damage occurs due to contamination or damage of surrounding articles by the scattered fire extinguishing agent.
Further, there is a problem that a sprinkler fire extinguishing system using tap water does not always start fire extinguishing as soon as possible because it operates when the temperature rise due to the hot air flow satisfies the operating condition and does not operate if the size of the fire is not large to some extent. Further, the sprinkler head locally sprays the fire extinguishing water with the installation place as a spray point, and when the discharge amount per unit time is limited like tap water, it is difficult to secure a sufficient spray range and a sufficient spray amount, and there is a possibility that fire cannot be sufficiently extinguished.
Further, in a conventional fire extinguishing sheet, a fire extinguishing agent (such as a dry powder fire extinguishing agent or a fire extinguishing liquid) is sealed in a soluble sheet (film), and the fire extinguishing sheet is melted by heat generated by a fire when it is covered on a fire source, and the sealed fire extinguishing agent is discharged to extinguish the fire. However, since the amount of the fire extinguishing agent sealed in the fire extinguishing sheet is relatively small, it is conceivable that a sufficient fire extinguishing effect cannot be obtained. In addition, when there is no flame like a smoldering fire, it takes time for the sheet to melt and discharge the fire extinguishing agent, and there is a possibility that the sheet does not work for initial fire extinguishing.
The invention aims to provide a fire extinguishing apparatus and a fire extinguishing facility which are easy to install and can effectively extinguish fire with a small amount of spraying amount.
Another object of the present invention is to provide a fire extinguishing apparatus and a fire extinguishing method that can be easily used by a user, can reliably extinguish a fire, and can also reduce secondary damage.

Effects of the invention
(basic effect of fire extinguishing apparatus fixedly set)
In the fire extinguishing apparatus of the present invention, the sheet member is disposed in a room or the like as a protective fence, and a plurality of discharge ports are disposed at each position of the sheet member located on one surface side facing the inside of the protective fence, for example, and the sheet member is discharged from the plurality of discharge ports to perform surface discharge in the event of a fire.
Here, "surface discharge" refers to discharge of the fire extinguishing agent in a surface form from a plurality of portions by disposing a plurality of discharge ports (discharge points) at each of the sheet surfaces of the sheet body, that is, discharge of the fire extinguishing agent from the discharge ports disposed at each of the sheet surfaces to discharge the fire extinguishing agent from a wide range of the sheet surfaces. In addition, "dot discharge" means that a discharge port (discharge point) exists at 1 point (installation site) and the fire extinguishing agent is discharged from 1 point. Further, the case where the fire extinguishing agent is discharged linearly from a plurality of discharge ports arranged linearly in a line is referred to as "line discharge".
Further, the sheet member has a size corresponding to the size of the opening, wall surface, ceiling surface, etc. of the protection fence, for example, if the amount of fire extinguishing agent discharged from each discharge port is reduced, the fire extinguishing agent can be discharged to each corner of the target space with a relatively small pressure using the fire extinguishing agent smaller than the amount of fire sprayed from the sprinkler head as a whole, and a fire protection device can efficiently extinguish a fire in a predetermined range in a short time with little influence on the outside.
Further, in the case where the ejection port for ejecting the fire extinguishing agent mainly in the direction perpendicular to the sheet surface is used when the sheet body is spread from the top to the bottom (spread along the side surface of the protected area), the fire extinguishing agent is ejected in the lateral direction (from the side of the protected area, for example, to the room), and the fire extinguishing agent can reach even a position that is not visible from the top, such as below a table or desk installed in the room or the like, and can reliably extinguish a fire. Further, "fire extinguishing" refers to a concept of suppressing combustion or extinguishing a fire. Here, "suppression" means suppression of, for example, fire spread, combustion speed, or combustion scale-up.
(effect of unfolding sheet body in case of fire)
Further, since the sheet member having the fire extinguishing agent flow path and the discharge port has flexibility, the sheet member is not spread (for example, rolled up in a cylindrical shape) and is disposed on the upper portion of the wall surface side of the room at a predetermined position of the boundary portion of the guard fence in a normal state, for example, and the installation space can be made small.
Further, when the sheet body is released from holding at the time of fire occurrence, the other end of the sheet body having one end fixed falls downward and is developed from above downward, and the fire extinguishing agent can be discharged in a planar manner from the discharge ports arranged at each position of the developed sheet body to extinguish the fire.
(effect of expansion action of sheet body based on fire extinguishing agent supply)
In addition, the non-expanded state of the holding sheet body can be released and expanded using the distribution pressure of the fire extinguishing agent supplied at the time of fire occurrence as a driving source. Further, since the electrical holding releasing operation is not required, the sheet body can be reliably spread and the fire extinguishing agent can be discharged even in the event of a power failure.
(effect of fixed setting of unfolded sheet body)
The sheet member may be initially set in an expanded state (expanded state) on a wall surface of a room as a barrier, and the fire extinguishing agent may be discharged in a planar manner from a plurality of discharge ports arranged at various positions of the sheet member to extinguish a fire in the event of a fire.
(Effect of sheet body construction 1)
Further, by the sheet structure in which the crushable and deformable sheet pipe in which the fire extinguishing agent supply port and the discharge port are arranged is arranged between the two covering sheets (the 1 st covering sheet and the 2 nd covering sheet), a flexible sheet body having the fire extinguishing agent flow path and the discharge port can be manufactured simply and easily at low cost.
(Effect of sheet Structure 2)
Further, since the 1 st covering sheet, the 1 st waterproof sheet, the 2 nd waterproof sheet, and the 2 nd covering sheet may be sewn together in a laminated state to form the fire extinguishing agent flow path in which the fire extinguishing agent supply port and the discharge port are arranged, the formation of the fire extinguishing agent flow path and the integration of the laminated sheet bodies can be simultaneously achieved by sewing, the flexible sheet bodies having the fire extinguishing agent flow path and the discharge port can be produced more easily and easily, the mass production is also easy, and the production cost can be further reduced.
In addition, the fire extinguishing agent flow path can be formed in an arbitrary path pattern simply and easily by, for example, sewing with a sewing machine or bonding with an adhesive.
(Effect of cover sheet)
Further, since the covering sheet (the 1 st covering sheet, the 2 nd covering sheet) has fire-proof property, fire-resistant property, heat-insulating property, flame-retardant property, or smoke-retardant property, the fire extinguishing agent can be continuously discharged without burning even if it receives heat or flame generated by a fire, and when the covering sheet is arranged and expanded in an opening such as an entrance or the like which is a boundary portion of a protection fence, the fire can be prevented from spreading and an evacuation route can be secured by flame-blocking, heat-insulating, and smoke-blocking with respect to the outside of the protection fence. Further, due to the flexibility of the cloth-like body, the sheet body can be evacuated from the inside of the protective partition to the outside even after being unfolded.
(wetting effect of fire extinguishing agent on sheet body)
In addition, when the fire extinguishing agent flow path is formed by, for example, sewing or bonding, the fire extinguishing agent is discharged as a coolant to the outside of the fire extinguishing agent flow path to wet the sheet body, thereby improving the flame resistance, smoke resistance, and heat insulation properties of the sheet body.
(effect of arrangement of fire extinguishing agent flow path with respect to discharge port array)
Further, by supplying the fire extinguishing agent from both ends of the ejection port row element in which the plurality of ejection ports are arranged in the transverse direction, for example, of the sheet body, the ejection pressures of the plurality of ejection ports can be made substantially uniform, and the ejection pattern (angular distribution) and the ejection amount of the fire extinguishing agent can be made uniform.
(Effect of installation site of fire extinguisher)
Further, in the fire extinguishing apparatus, the sheet surface is arranged along the boundary surface of the boundary portion at an arbitrary position, for example, the entrance, the wall surface, the window, the ceiling surface, or the like of the room, which is the boundary portion of the protection plan, for example, in the expanded state of the sheet body, so that the fire extinguishing apparatus can be easily installed and used in the non-expanded state or the expanded state of the sheet body, and the fire extinguishing apparatus can be installed optimally in accordance with the usage form of the room.
(Effect of pressure buffer Unit)
Further, when the fire extinguisher is opened to supply the fire extinguishing agent to the fire extinguishing agent flow path, the accumulated pressure of the fire extinguisher is high, for example, 0.7MPa to 0.98MPa, and if the fire extinguishing agent is applied to the fire extinguishing agent flow path of the fire extinguishing device at the time of opening the fire extinguisher, there is a possibility that these will be damaged, and therefore, for example, a buffer region is provided on the inlet side of the fire extinguishing agent flow path as a pressure buffer means, and the rise (or rise rate) of the fire extinguishing agent supply pressure from the fire extinguisher is made to be a predetermined value or less, thereby preventing the fire extinguishing agent flow path and the discharge port from being damaged. Further, by providing the 2 nd pressure buffer means such as a tank or an orifice at the fire extinguishing agent supply port, the rise (or rate of rise) of the fire extinguishing agent supply pressure from the fire extinguisher is similarly made to be equal to or less than a predetermined value, thereby preventing the fire extinguishing agent flow path and the discharge port from being damaged.
(Effect of fire extinguishing facility 1 Using piping for tap Water)
Further, since the tap water pipe is connected to the fire extinguishing agent pipe and tap water is discharged as the fire extinguishing agent from the discharge port of the fire extinguishing device in the event of a fire, a dedicated pump device is not required, and the installation is easy and the cost can be reduced.
(effect of fire extinguishing apparatus 2 Using extinguisher)
Further, a fire extinguishing agent supply device such as a nozzle of a fire extinguisher is connected to a fire extinguishing agent supply port via a fire extinguishing agent pipe, and a fire extinguishing agent such as a dry powder fire extinguishing agent or a reinforcing liquid fire extinguishing agent is sprayed into a protected area from a spray port of the fire extinguishing device by a fire extinguishing agent opening operation of the fire extinguisher at the time of a fire occurrence, whereby fire can be effectively extinguished.
Further, even if the operation of the fire extinguisher as the fire extinguishing agent supplying tool is not familiar, the fire extinguishing agent such as the dry powder fire extinguishing agent can be supplied to the fire extinguishing tool installed in the room at a high pressure by pulling out the safety pin of the fire extinguisher disposed, for example, on the outside of the room as the protected area and holding the handle, and the dry powder fire extinguishing agent can be discharged from the discharge port of the fire extinguishing tool to a wide range while the sheet body is spread, thereby effectively extinguishing the fire in a short time.
(effect of fire extinguisher using fire extinguisher and water piping 3)
In addition, in addition to the effects of the fire extinguishing system 1 using the water supply line pipe and the fire extinguishing system 2 using the fire extinguishing device described above, the fire extinguishing agent supply device, such as a fire extinguisher, is operated to open the hydrant, and the fire extinguishing agent, such as a dry powder fire extinguishing agent or a reinforcing liquid fire extinguishing agent, is discharged from the discharge port of the fire extinguishing device into the protective area at the time of a fire occurrence, whereby initial fire extinguishment is performed, and the time for which the fire extinguisher continues to discharge the fire extinguishing agent is short, for example, for ten seconds.
(Effect of the Structure of the piping opening/closing means)
In the fire extinguishing system 1 or 3, the remote opening/closing valve is opened by remote control based on a control signal from the fire detection system in response to the occurrence of a fire in the protected area, whereby the fire extinguishing agent can be discharged from the discharge port of the fire extinguishing device in conjunction with the fire detection, and the fire extinguishing agent can also be discharged from the fire extinguishing device by manual opening operation of the manual opening/closing valve.
(Effect of connection Unit of extinguisher)
Further, since the fire extinguishing device is detachably connected to the fire extinguishing agent pipe by the connecting means, when the fire extinguisher runs out, the fire extinguishing agent can be continuously discharged by replacing the fire extinguishing device with an unused fire extinguisher as needed, and fire can be reliably extinguished. Further, if a plurality of coupling units having a check valve structure are provided and the fire extinguisher is connected to each other, the work of attaching and detaching and replacing the fire extinguisher can be omitted, the fire extinguishing agent can be rapidly continuously discharged, and the fire can be reliably extinguished.
In addition, when a fire breaks out in a place outside the protected area where no fire extinguishing device is installed, the fire extinguisher can be removed by the coupling means of the fire extinguishing agent pipe and transported to the place for use.
(Effect of the 2 nd pressure buffering Unit of the fire extinguishing agent supplying System)
In the fire extinguishing system 2 or 3, the 2 nd pressure buffering means is provided at the connection means or the fire extinguishing agent pipe of the fire extinguishing agent supply system, and the rise (or the rate of rise) of the fire extinguishing agent supply pressure from the fire extinguisher is made to be a predetermined value or less, thereby preventing the fire extinguishing agent flow path and the discharge port from being damaged.
(basic effect of Portable fire extinguisher)
In the fire extinguishing device of the present invention, when extinguishing a fire such as a fire, a user places the sheet body with one surface of the sheet body facing downward and covers the sheet body over, for example, a fire source, and performs a bolt opening operation on a fire extinguishing agent supply device such as a fire extinguisher to eject a fire extinguishing agent in a planar manner from an ejection port arranged on the surface of the sheet body, that is, the surface facing the side to be extinguished, thereby efficiently ejecting the fire extinguishing agent to the fire source covered with the sheet body, and a synergistic effect of, for example, cooling by the fire extinguishing agent and blocking oxygen supply (suffocation) by being covered with the sheet body can be obtained, and reliable fire extinguishing can be achieved.
Here, "fire source" is a concept indicating a fire source (combustion source) and its surroundings, and the like. The term "surface discharge" refers to a discharge of the fire extinguishing agent in a surface form from a plurality of locations by disposing a plurality of discharge ports (discharge points) at respective positions on one surface of the sheet body, that is, a discharge of the fire extinguishing agent from discharge ports disposed at respective positions on one surface of the sheet body to spray the fire extinguishing agent from a wide area on one surface of the sheet body. The terms "cover" and "cover" are not limited to covering the entirety of an object (e.g., a fire source) or covering the entirety of the object, and include covering a part of an object or covering a part of an object.
Further, the sheet member may have a size that can cover a virtual fire-extinguishing object including a device or a place that may be a fire source such as a gas range or a heating appliance, and the fire-extinguishing device can be simplified by adopting a relatively small size.
(Effect of shape of sheet body)
Further, since the sheet body has a sheet shape corresponding to the fire extinguishing target as the fire source, when a fire breaks out in the fire extinguishing target, for example, a gas range, a heating appliance, or the like, the sheet body can cover and discharge the fire extinguishing agent so that a gap is not easily formed between the boundary portion between the space on the fire source (fire extinguishing target) side covered with the sheet body and the external space.
(effect of weighting of outer periphery of sheet body)
Further, since the weight is provided along the outer peripheral edge of the sheet body, when the user spreads the sheet body and throws the sheet body to cover the fire source, the sheet body can be thrown while spreading the sheet body by the weight on the outer peripheral edge like a net throwing, and the sheet body can be easily and reliably covered on the fire source. Further, the floating of the sheet body at the time of ejecting the fire extinguishing agent is pressed by the weight on the outer peripheral edge, and the fire extinguishing agent can be prevented from leaking and scattering from the space covered with the sheet body, thereby improving the fire extinguishing effect and reducing the contamination around.
(effect of normally setting the sheet body to a non-expanded state)
In addition, the sheet body is normally disposed in the vicinity of the fire extinguishing object and is in a non-expanded state, for example, stored in the storage unit or hung on the rack unit, and preferably folded into a bag-like state so as to use a small installation space, whereby, for example, in the event of a fire, the user can quickly take out and expand the sheet body without looking for a place to place, cover the fire source, and eject the fire extinguishing agent from the fire extinguishing sheet surface of the sheet body in a planar manner.
(effect of normally disposing sheet body on fire-extinguishing object)
In addition, in a case where a fire is caused by a fire, the user can quickly extinguish the fire by simply performing a bolt-releasing operation on a fire extinguishing agent supplying tool such as a fire extinguisher without performing an operation of spreading the sheet body to cover the fire source by covering the sheet body in a spread state on a predetermined fire extinguishing target (for example, furniture such as a bed using an electric blanket that may become a fire source) in a normal state.
The effects other than the above of the portable fire extinguishing device are the same as those of the fixedly installed fire extinguishing device.

[ A. basic concept of embodiment ]
First, the basic concept of the embodiment of the fixedly installed fire extinguishing apparatus and fire extinguishing equipment will be explained. The present invention is not limited to the following embodiments.
Embodiments generally relate to fire extinguishing appliances and fire extinguishing equipment. "fire extinguishing apparatus" refers to an apparatus that sprays or sprays a fire extinguishing agent to extinguish a fire. Here, the "guard division" is a concept as follows: the fire extinguishing apparatus is a partition provided with a fire extinguishing apparatus, for example, an external partition including a building, an internal partition within the building, and an internal partition within the building, for example, a room including the building, a corridor, a staircase, and the like.
The fire extinguishing apparatus of the embodiment has a sheet body, a fire extinguishing agent flow path, a fire extinguishing agent supply port, and a discharge port. The "sheet body" is a concept as follows: for example, the fabric is flexible, thin and large, and can be used for covering or covering, and includes, for example, a fabric-like body that can be held in an undeployed state or released from the undeployed state to be brought into a deployed state.
In addition, the "fire extinguishing agent flow path" is a concept as follows: the present invention refers to a channel for flowing a fire extinguishing agent provided in a sheet body, and includes, for example, a sheet pipe disposed between cloth bodies. The "sheet pipe" is, for example, a flexible pipe that can be crushed and deformed freely and that expands when a fire extinguishing agent flows therethrough.
In addition, the "fire extinguishing agent supply port" is a concept as follows: the inlet for supplying the fire extinguishing agent to the fire extinguishing agent flow path provided in the sheet body includes, for example, a connection port of a fire extinguishing agent pipe.
The "discharge port" is an outlet of the fire extinguishing agent supplied from the fire extinguishing agent supply port to the fire extinguishing agent flow path, and discharges the fire extinguishing agent from each location on at least one surface side of the sheet body.
In addition, the fire extinguishing apparatus has a sheet unwinding unit. Here, the "sheet spreading means" is a means for holding the sheet body at a predetermined position of the boundary of the protection plan in a non-spread state in a normal state and releasing the holding of the sheet body to spread the sheet body in the case of a fire, and for example, in the normal state, the sheet body is held at the upper ceiling side of the opening (e.g., the entrance of a room) of the boundary of the protection plan in the non-spread state in which it is rolled up, and in the case of a fire, the holding of the sheet body is released to spread the sheet body, so that in a state in which one end edge (upper end edge) is fixed, the other end edge (lower end edge) falls by its own weight and spreads from above to below, thereby closing the opening.
In addition, the "fire extinguishing apparatus" is a concept as follows: the term "equipment for extinguishing a fire using a fire extinguishing apparatus" includes, for example, equipment for operating a fire extinguishing apparatus by a manual fire extinguishing operation, equipment for detecting a fire by a fire detection apparatus or the like in which a detector is connected to a receiver, and equipment for automatically operating a fire extinguishing apparatus.
Fire extinguishing equipment using a fire extinguishing apparatus includes a fire extinguishing agent pipe and a fire extinguishing agent supply source. Here, the "fire extinguishing agent pipe" is a concept as follows: the piping is a piping for supplying a fire extinguishing agent to a fire extinguishing apparatus, and includes, for example, piping or hoses for supplying fire extinguishing water, a liquid fire extinguishing agent, a dry powder fire extinguishing agent, and the like to the fire extinguishing apparatus. In addition, the "fire extinguishing agent supply source" is a concept as follows: the fire extinguishing agent supply source is a source for supplying a fire extinguishing agent to a fire extinguishing agent pipe, and includes, for example, a water pipe for supplying tap water, a pressurized water supply device having a pump for supplying fire extinguishing water, a water storage tank, an overhead water tank, and a fire extinguishing agent supply device such as a fire extinguisher.
In the following description, first, specific contents of the embodiments of the fire extinguishing equipment and the fire extinguishing facility will be described with respect to the case where the "protected area" is a "room of a building and the" fire extinguishing agent supply source "is a" water pipe line "and/or a" fire extinguisher ". Next, the basic concept and specific contents of the embodiment will be described with respect to a warehouse fire-extinguishing facility using a fire-extinguishing apparatus.
[ details of the embodiments ]
The specific contents of the embodiments will be described with respect to a fire extinguishing apparatus and a fire extinguishing facility which are fixedly installed.
(B1. Structure of fire extinguishing apparatus and fire extinguishing facility)
As shown in fig. 1, the fire extinguishing device 12 of the present embodiment is installed at the upper part of a boundary portion (e.g., the doorway 11) of a room as the protected area 10, for example, at a home of a cognitive aged person or the like. In the fire extinguishing device 12, the sheet body 28 using a flexible cloth-like body is normally held in the main body 62 in a non-spread state, for example, wound in a cylindrical shape, and the sheet body 28 is provided with a fire extinguishing agent flow path and a plurality of discharge ports. Here, as shown in the drawing, the vertical direction in which the ceiling surface on which the fire detector 14 is provided is located is referred to as a vertical direction or a height direction, the direction perpendicular to the vertical direction and connecting the left and right wall surfaces when viewed from the entrance 11 (opening) which is a boundary of a room is referred to as a left-right direction or a lateral direction, and the direction from the entrance 11 toward the inside of the room is referred to as a depth direction with respect to the guard fence 10 of fig. 1.
In the guard fence 10, a fire detector 14 is connected as a fire detection device to a receiver 16. The fire extinguishing apparatus 12 is connected to a fire extinguishing agent pipe 20 from a water pipe 18 of a water pipe facility via a gate valve 25. A remote on-off valve 24 and a manual on-off valve 26 are connected in parallel to the fire extinguishing agent pipe 20 as pipe opening/closing means for opening/closing the pipe flow path by remote control or manual operation. Here, the fire extinguishing apparatus of the present embodiment includes a fire extinguishing device 12, a fire extinguishing agent pipe 20, a remote opening/closing valve 24, a manual opening/closing valve 26, and a water pipe 18.
The remote on-off valve 24 is an electromagnetic valve or an electrically operated valve, and when receiving a fire signal from the fire detector 14 provided in the protected area 10, the receiver 16 outputs a control signal (opening control signal) to the remote on-off valve 24 to open the valve, and supplies tap water as a fire extinguishing agent to the fire extinguishing device 12.
When the remote opening/closing valve 24 is opened to supply tap water to the fire extinguishing device 12, a sheet expanding portion described later is operated to release the holding of the sheet body 28, and as shown in fig. 2, one end edge of the sheet body 28 is expanded from above to below (in the longitudinal direction) to close the entrance 11 of the protection area 10, and tap water is supplied to the fire extinguishing agent flow path of the sheet body 28, and tap water is discharged from the plurality of discharge ports 30 into the protection area 10 to extinguish a fire.
Here, the deployed sheet member 28 is set to have a vertical direction (height direction) and a horizontal direction perpendicular to the vertical direction, and tap water is ejected as a fire extinguishing agent into the depth direction in the protected area 10 from, for example, an ejection port row in which 3 ejection ports 30 × 3 ejection ports 30 are arranged in the vertical direction to extinguish a fire. At this time, the tap water is sprayed from the side into the guard fence 10.
As shown in fig. 3, the ejection distances of the ejection ports 30 arranged in, for example, 3 stages in the longitudinal direction (vertical direction) of the sheet body 28 are set such that the ejection ports 30 are located farther as the position is higher, and substantially the entire region covering the ground surface side of the guard fence 10 is set as the ejection range. In addition, when furniture such as a dining table 31 is placed in the guard fence 10, the water jet from the ejection port 30 of the spread sheet material 28 can reach the lower side of the dining table 31. When water is sprayed onto the ceiling surface, the uppermost part of the discharge ports 30 may be directed upward so as to wet the ceiling surface and prevent the spread of fire.
The fire extinguishing agent (tap water) is discharged from the plurality of discharge ports 30 disposed at each position of the spread sheet-like body 28 as a whole as a surface, and is discharged at a point which is one point with respect to the discharge point in the case where a conventional sprinkler head is provided on the ceiling surface, so that even if the discharge amount is the same, a large discharge range (water spray range) can be covered, and the fire extinguishing agent can reach a position which cannot be seen from above such as below the table 31 or desk, and as a result, fire can be extinguished with a small discharge amount of the fire extinguishing agent.
(B2. fire extinguishing facility of family of cognitive disease old man)
As shown in fig. 4, in the fire extinguishing facility of the cognitive elderly using the fire extinguishing apparatus 12 according to the present embodiment, the fire extinguishing apparatus 12 is provided in, for example, an upper portion of an entrance of each room as the protective bay 10(10-1, 10-2.. 10-n), one end side of the fire extinguishing agent pipe 20 is connected to a fire extinguishing agent supply port of the fire extinguishing apparatus 12, and the other end side of the fire extinguishing agent pipe 20 is connected to the water pipe 18 of the water pipe facility via a remote on-off valve 24 and a manual on-off valve 26 connected in parallel. In addition, the gate valve 25 shown in fig. 1 is omitted.
The fire detectors 14 respectively provided in the guard bays 10(10-1, 10-2.. 10-n) are connected to the receivers 16, and the receivers 16 monitor each guard bay (room) for a fire.
When a fire breaks out in any of the protection bays 10(10-1, 10-2.. 10-n), the corresponding fire detector 14 issues an alarm and transmits a fire signal to the receiver 16, the receiver 16 outputs a control signal (opening control signal) to open the remote on-off valve 24 corresponding to the protection bay where the fire breaks out in accordance with the fire signal, and supplies a fire extinguishing agent (tap water) to the fire extinguishing device 12 installed in the protection bay where the fire breaks out, and as shown in fig. 2 and 3, the sheet member 28 of the fire extinguishing device 12 is spread out and the fire extinguishing agent (tap water) is ejected in a planar manner from the plurality of ejection ports 30 arranged at each position of the spread sheet member 28 to extinguish the fire.
[ sheet Material for fire extinguishing apparatus ]
(C1. Structure of sheet body)
The sheet body 28(28a) of the present embodiment shown in fig. 5 is a rectangular sheet body having a longitudinal and lateral length corresponding to the size of the installation place (e.g., entrance/exit) of the protective partition in the unfolded state, and is flexible by using a cloth-like body, and can be easily put into the unfolded state by being rolled into a cylindrical shape or the like.
A fire extinguishing agent supply port 32 as a fire extinguishing agent inlet is disposed on one end (upper end) side of the sheet body 28, a fire extinguishing agent flow path 34 indicated by a broken line is provided inside, and a plurality of discharge ports 30 are disposed at each position of the fire extinguishing agent flow path 34. In the present embodiment, the ejection ports 30 are arranged at 9 of the vertical and horizontal 3 rows.
The fire extinguishing agent flow path 34 is formed in a ladder shape having 4 stages in the vertical direction (the direction in which the fire extinguishing agent flows down), the fire extinguishing agent supply port 32 is provided at the center of the 1 st stage which is the uppermost stage, and 3 discharge ports 30 are arranged from the 2 nd stage to the 4 th stage, for example.
The discharge port rows arranged in the horizontal direction at each stage are used as one discharge port row element, and the discharge port row elements are arranged in 3 stages from the 2 nd stage to the 4 th stage as an entire discharge port row, and the fire extinguishing agent flow path 34 is formed to supply the fire extinguishing agent to the horizontal discharge port rows arranged at the discharge ports 30 of the 2 nd stage to the 4 th stage from both end sides of each discharge port row element. This makes it possible to substantially equalize the discharge pressure of the fire extinguishing agent supplied to the plurality of discharge ports 30 in the same row, and to equalize the discharge pattern (angular distribution) and the discharge amount in the same row.
The form of the fire extinguishing agent flow path 34 for supplying the fire extinguishing agent to the plurality of discharge ports 30 is not limited to the ladder shape shown in the figure, and may include an appropriate form such as a tree shape or a championship tree shape. In order to make the discharge pressures of the plurality of discharge ports 30 substantially uniform, the thickness (cross-sectional area) of the fire extinguishing agent flow path 34 may be made large on the fire extinguishing agent supply port 32 side and may be made small as it is farther from the fire extinguishing agent supply port 32. The number and arrangement of the discharge ports 30 provided corresponding to the fire extinguishing agent flow path 34 are arbitrary.
(C2. method for producing sheet Material 1)
The sheet body 28(28a) of the present embodiment shown in fig. 5 is produced by, for example, the method shown in fig. 6. First, the 1 st cover sheet 36 and the 2 nd cover sheet 38 having a predetermined size are prepared. The 1 st cover sheet 36 and the 2 nd cover sheet 38 are, for example, cloth-like bodies having fire-proof, fire-resistant, heat-resistant, or flame-retardant properties, and can withstand high heat of 1200 ℃. The 1 st cover sheet 36 and the 2 nd cover sheet 38 also have heat insulating properties, flame retarding properties, smoke retarding properties, and the like. Further, only the covering sheet facing the inside of the guard fence may have fire resistance, heat resistance, fire resistance, heat insulation, or flame retardancy.
Next, the sheet piping 40, which is, for example, a 4-step ladder shape, is prepared. The sheet pipe 40 is obtained by, for example, forming a cloth-like body of polyester or the like used for umbrella production into a tubular shape and connecting the tubular shape to a ladder shape (a connecting portion through which the flow can be passed), and as shown in fig. 7 (a), the sheet pipe 40 is crushed and deformed freely and flattened by being crushed, and when the fire extinguishing agent 41 is supplied, as shown in fig. 7 (B), the sheet pipe 40 is expanded to form the fire extinguishing agent flow path 34.
As shown in fig. 6, the fire extinguishing agent supply port 32 and the discharge ports 30 are disposed in the sheet pipe 40, and the through-hole 56 is opened in the 1 st covering sheet 36 corresponding to the discharge ports 30.
The discharge port 30 has a structure shown in fig. 8, for example. The ejection port 30 has a pedestal 42 and a retainer ring 44. A screw shaft 46 is erected on the base 42, and a discharge hole 50 penetrates the screw shaft 46. The clamp ring 44 has a threaded bore 48, and the clamp ring 44 is threaded into and secured to the threaded shaft 46.
As shown in fig. 8 (a), the base 42 is disposed in the sheet pipe 40, and is fixed by adhesion via an adhesion portion 43 as shown in fig. 8 (C), for example, so that the screw shaft 46 is extended to the outside. The screw shaft 46 extending from the opening provided in the sheet pipe 40 extends through the through hole 56 (see fig. 6) of the 1 st cover sheet 36, and the clamp ring 44 is screwed thereon, whereby the sheet pipe 40 is clamped and fixed in a state of being disposed on the back surface of the 1 st cover sheet 36.
Next, as shown in fig. 6, the sheet 28(28a) shown in fig. 5 is completed by disposing the sheet pipe 40 provided with the ejection port 30 and the fire extinguishing agent supply port 32 on the back side of the 1 st covering sheet 36, disposing the 2 nd covering sheet 38 on the opposite side of the 1 st covering sheet 36 with the sheet pipe 40 interposed therebetween, sandwiching the sheet pipe 40 between the 1 st covering sheet 30 and the 2 nd covering sheet 32, and bonding the 1 st covering sheet 30 and the 2 nd covering sheet 32 together or sewing them with a waterproof thread.
Here, the discharge hole 50 provided in the base 42 of the discharge port 30 determines the opening diameter of the discharge port 30, and since the water pressure of tap water supplied as the fire extinguishing agent is about 0.02MPa, a hole diameter of about 3 mm to 4 mm, for example, is adopted.
The pore diameter of about 3 mm to 4 mm is equivalent to the pore diameter of one of a plurality of water jetting holes formed in a common shower head using tap water. Therefore, a discharge pattern of tap water corresponding to 1 hole of the shower head can be obtained from the discharge ports 30, and the discharge pattern is discharged from the plurality of discharge ports 30 arranged at each position of the sheet 28, thereby achieving surface discharge as a whole.
The discharge holes 50 function as nozzles for determining the discharge pattern of the fire extinguishing agent. For example, the straight ejection hole 50 shown in the figure forms an ejection pattern with a relatively narrow angle, and if the outlet opening of the ejection hole 50 is expanded in a conical shape, a wide-angle ejection pattern expanded in a conical shape is formed, and an appropriate opening shape can be adopted according to a desired ejection pattern. The ejection ports 30 having different opening shapes may be mixed appropriately.
In the present embodiment, the center axis of the discharge hole 50 (the dashed dotted line in the drawing) is perpendicular to the sheet surface, but the present invention is not limited thereto. For example, the directivity of the fire extinguishing agent discharge may be adjusted by adjusting the inclination angle of the central axis with respect to the sheet surface.
As a wetting means (cooling means) for wetting and cooling the 1 st cover sheet 36 and the 2 nd cover sheet 38 independently of the ejection port 30, a coolant ejection port may be provided in a sheet pipe 40 constituting a fire extinguishing agent flow path, or a coolant sheet pipe constituting a coolant flow path may be provided independently of the sheet pipe 40 or branched from the sheet pipe 40, and a coolant ejection port may be provided in the coolant sheet pipe. This can improve the fire resistance, heat resistance, and the like of the 1 st covering sheet 36 and the 2 nd covering sheet 38, and can reduce the cost by using a sheet of a low grade.
(C3. method for producing sheet Material body 2)
Fig. 9 is an explanatory diagram illustrating another manufacturing method of the sheet body 28. The sheet member 28(28b) of fig. 9 is prepared with the 1 st covering sheet 36, the 1 st waterproof sheet 52, the 2 nd waterproof sheet 54, and the 2 nd covering sheet 38 having predetermined sizes. The 1 st cover sheet 36 and the 2 nd cover sheet 38 are the same as the manufacturing method of fig. 6, and the 1 st waterproof sheet 52 and the 2 nd waterproof sheet 54 are cloth-like bodies of polyester or the like used for umbrella manufacturing, for example, as in the sheet pipe 40 of the manufacturing method of fig. 6.
The 1 st waterproof sheet 52 has the fire extinguishing agent supply port 32 disposed corresponding to the fire extinguishing agent flow path 34 to be formed, and through holes 56, 58 formed corresponding to the discharge ports 30.
As shown in fig. 10, the 1 st covering sheet 36 and the 1 st waterproof sheet 52 are fixed by attaching the ejection port 30 in a state where the through holes 56 and 58 of the 1 st covering sheet 36 and the 1 st waterproof sheet 52 are aligned and overlapped. The structure of the ejection port 30 is the same as that shown in fig. 8, and includes: a base 42 having a screw shaft 46, and a discharge hole 50 penetrating the screw shaft 46; and a clamp ring 44 having a threaded bore 48.
In a state where the 1 st covering sheet 36 and the 1 st waterproof sheet 52 are fixed to each other through the spout 30, as shown in fig. 9, the 2 nd waterproof sheet 54 and the 2 nd covering sheet 38 are superimposed, and in this state, as shown in fig. 11, a sewn portion 60 is formed by a sewing operation using a waterproof thread by a sewing machine or the like, for example, to produce the fire extinguishing agent flow path 34. In addition, in a state where the sheets are stacked, the peripheral edges of the sheets are sewn to obtain sewn portions 61, and the sewn portions 61 are integrated to form the sheet body 28.
Fig. 12 (a) shows the fire extinguishing agent flow path 34 formed by a sewn portion 60, the sewn portion 60 being obtained by sewing the 1 st covering sheet 3, the 1 st waterproof sheet 52, the 2 nd waterproof sheet 54, and the 2 nd covering sheet 38 with waterproof thread by a sewing machine, for example, and when the fire extinguishing agent 41 is supplied, the fire extinguishing agent flow path 34 is in a crushed state in normal times and the fire extinguishing agent flow path 34 is expanded as shown in fig. 12 (B) to allow the fire extinguishing agent to flow therethrough.
Here, the sealing performance of the fire extinguishing agent flow path 34 is improved by doubling the sewn portion 60, but when tap water is supplied as the fire extinguishing agent, a small amount of tap water may leak from the seams. However, tap water leaking from the fire extinguishing agent flow path 34 wets the sheet body 28, thereby improving fire resistance, heat insulation, flame retardancy, and smoke resistance against fire.
As described above, as a wetting means (cooling means) for wetting and cooling the 1 st covering sheet 36 and the 2 nd covering sheet 38 independently of the spout 30, a coolant spout may be provided on the fire extinguishing agent flow path 34 formed by the sewn portion 60. The sewing portion 60 forming the fire extinguishing agent flow path 34 may be adjusted such that, for example, the stitches are locally enlarged, or the stitches are locally jumped, or the gaps are locally enlarged to form the coolant discharge ports. Further, the flow path (cooling flow path) provided with the coolant discharge port may be provided independently of the fire extinguishing agent flow path. Further, although the fire extinguishing agent doubles as a coolant here, the fire extinguishing agent and the coolant may be different. In this case, the coolant pipe may be provided separately from the fire extinguishing agent pipe, and the coolant supply port having the same configuration as the fire extinguishing agent supply port may be provided separately from the fire extinguishing agent supply port and connected to the coolant pipe.
[ Structure of sheet development ]
(D1. sheet spreading structure)
As shown in fig. 13 (a) and (B), in the fire extinguishing device 12 of the present embodiment, one end edge (upper end edge when deployed) of the sheet body 28 is fixed to the main body 62 by the sheet fixing portion 63, and in a normal state, the sheet body 28 is held in a suspended state at a plurality of places by the sheet holding members 64 in a non-deployed state wound in a cylindrical shape, the sheet holding members 64 using a wire or a rope.
The sheet holding member 64 has one end fixed to the main body 62 and the other end detachably held by a sheet holding releasing portion 66 on the opposite side (fixed opposite side) of the main body 62 via the outer peripheral lower side of the sheet roll of the sheet body 28. The sheet holding releasing portion 66 is operated by receiving the supply of the fire extinguishing agent from the fire extinguishing agent pipe 20, and releases the holding sheet holding member 64.
When the sheet holding releasing portion 66 releases holding of one end of the sheet holding member 64, as shown in fig. 13 (C) and (D), in a state where one end (upper end) of the sheet body 28 is fixed to the main body 62, the other end (lower end when unfolded) side opposite thereto falls due to its own weight and is unfolded from the upper side to the lower side (vertical direction). Further, a predetermined weight member may be provided on the lower end side of the sheet body 28, so that the falling of the lower end side of the sheet body 28 and the stabilization after the sheet body 28 is developed can be assisted.
(D2. Structure of sheet development part)
As shown in fig. 14, the sheet holding/releasing portion 66 of the present embodiment is provided with an actuator 68 that operates upon receiving the supply of the fire extinguishing agent in the main body 62. In the actuator 68, a piston 72 is slidably attached to a cylinder 70 via a return spring 76, a cylinder chamber 70a is formed on one side of the piston 72, and the fire extinguishing agent pipe 20 is branched and connected to a fire extinguishing agent supply port 78. An automatic drain valve 73 is provided for the cylinder chamber 70 a. The automatic water discharge valve 73 is closed by the supply of the fire extinguishing agent exceeding a predetermined pressure, and when the pressure drops below the predetermined pressure, the automatic water discharge valve 73 is opened.
The piston 72 coaxially has a rod 74. An opening 82 is provided in the front surface portion of the main body 62 so that a part of the lever 74 can be visually recognized and the operation lever 80 provided in the lever 74 can be operated to be exposed.
When the sheet holding member 64 is to be held by the lever 74, the lever 74 is moved to the left by operating the lever 80, and the sheet body 28 wound in a cylindrical shape is held by inserting a fixed ring 64a, which is obtained by annularly connecting the tip of the sheet holding member 64 using a wire, through the lever 74.
In the event of a fire, tap water is supplied as a fire extinguishing agent to the cylinder chamber 70a via the fire extinguishing agent pipe 20, and the piston 72 is moved in the left direction against the return spring 76, whereby the rod 74 is disengaged from the retainer ring 64a, the sheet holding member 64 is released from holding, and the sheet body 28 falls by its own weight and is deployed from above to below.
The sheet holding/releasing portion 66 is provided with an actuator 68 that releases the holding of the sheet holding member 64 upon receiving the supply of the fire extinguishing agent, and thereby, even when power is interrupted, the sheet member 28 in the non-expanded state can be expanded and the fire extinguishing agent can be discharged in conjunction with the supply of the fire extinguishing agent.
The sheet holding releasing portion 66 is not limited to the above configuration, and may be configured to release the holding of the sheet holding member 64 by driving of an electromagnetic solenoid or the like in accordance with a control signal from the receiver 16 and to unfold the sheet body 28.
As the sheet material deployment structure of the fire extinguishing device 12, other suitable structures may be applied, and a structure may be employed in which the sheet material body 28 is wound around a rotation shaft, and the sheet material body 28 is deployed by releasing the latch of the rotation shaft, or a structure in which winding and unwinding are performed by driving a motor. Alternatively, the sheet member 28 may be held in a state folded in a bellows shape, and the holding may be released to unfold the sheet member 28.
In addition to the ladder-shaped arrangement shown in fig. 5 and 11, the fire extinguishing agent flow path 34 of the sheet body 28 may be arranged in a rectangular shape so as to surround the ladder-shaped periphery, and may function as a counterweight that assists the expansion of the sheet body 28 when fire extinguishing water is supplied as a fire extinguishing agent and stabilizes the expanded state. Further, the fire extinguishing agent flow path up to the nozzle 30 is long, and therefore, the fire extinguishing agent flow path can function as a buffer area that suppresses a pressure rise (or a rate of rise) at the start of supplying the fire extinguishing agent from the fire extinguisher to a predetermined level or less (to such an extent that the fire extinguishing agent flow path 34 and the discharge port 30 are not broken), as will be explained later.
[ E. fire extinguishing apparatus and fire extinguishing facility using fire extinguisher ]
As shown in fig. 15, in the present embodiment, a fire extinguisher is taken as an example of the fire extinguishing agent supply device, and a predetermined fire extinguishing agent (for example, a dry chemical fire extinguishing agent or a reinforcing liquid fire extinguishing agent) is supplied from the fire extinguisher 84 to the fire extinguishing device 12 provided at an upper portion of a boundary portion (for example, an entrance) of a room as the protected area 10 and is discharged.
The fire extinguisher 84 is filled with fire extinguishing agent in a pressure accumulating state in the main body container, and when the safety pin 90 is pulled out and the handle 92 is pressed, the fire extinguisher 84 is unlatched and fire extinguishing agent is ejected from the hose 86.
One end of the fire extinguishing agent pipe 20 is connected to the fire extinguishing agent supply port 32 provided in the sheet body 28(28c) of the fire extinguishing device 12, and the other end of the fire extinguishing agent pipe 20 is connected to a fire extinguisher nozzle 94a at the distal end of the hose 86 of the fire extinguisher 84 via a fire extinguisher connection portion 94 functioning as a connection means. The fire extinguisher coupling section 94 has a fire extinguisher nozzle 94a and a fire extinguisher connection port 94b, and uses a known coupling joint similar to a coupling joint for detachably connecting a hose to a faucet by a one-touch operation, for example.
Here, in the present embodiment, the fire extinguisher nozzle 94a is configured such that a nozzle attached to the hose end of the fire extinguisher 84 in advance is removed and a separately prepared fire extinguisher nozzle 94a is attached in advance, but the present invention is not limited thereto.
Fig. 16 shows an example of the fire extinguisher coupling portion 94, which includes a fire extinguisher nozzle 94a and a fire extinguisher connection port 94b, and the hose 86 of the fire extinguisher 84 can be attached to and detached from the fire extinguishing agent pipe 20 by providing the fire extinguisher nozzle 94a separately prepared at the tip of the hose 86 of the fire extinguisher 84 and providing the fire extinguisher connection port 94b at the other end of the fire extinguishing agent pipe 20.
The fire extinguisher nozzle 94a has a nozzle joint 95a to which an O-ring is attached at the tip, and the nozzle joint 95a is inserted into an opening of the fire extinguisher connection port 94b to be connected and fixed. The fire extinguisher connection port 94b has a slider 95b, and when the slider 95b is slid in the direction of the arrow shown in the figure, the connected fire extinguisher nozzle 94a can be removed.
Fig. 17 shows an embodiment of the sheet body 28(28c) for discharging the fire extinguishing agent from the fire extinguisher 84, in which a buffer area 96 is provided in the sheet body 28(28c) next to the fire extinguishing agent supply port 32, the fire extinguishing agent flow path 34 is provided via the buffer area 96, and the fire extinguishing agent flow path 34 is provided with discharge ports 30 at each location.
When the fire extinguisher 84 is opened to supply the fire extinguishing agent to the sheet body 28(28c), the accumulated pressure of the fire extinguisher 84 is high, for example, 0.7MPa to 0.98MPa, and if the fire extinguishing agent is applied to the fire extinguishing agent flow path 34 and the discharge port 30 of the sheet body 28(28c) at the time of opening the fire extinguisher 84, there is a possibility that these components may be damaged.
Therefore, a buffer area 96 is provided on the inlet side of the fire extinguishing agent flow path 34 as a pressure buffer means, and the fire extinguishing agent from the fire extinguisher 84 is temporarily retained to reduce the rise (or rate of rise) of the fire extinguishing agent supply pressure to a predetermined level or less in an initial stage after the start of the supply of the fire extinguishing agent, thereby preventing the fire extinguishing agent flow path 34 and the discharge port 30 from being damaged. The other structure is the same as the sheet member 28(28a) of fig. 5 or the sheet member 28(28b) of fig. 11.
In addition, instead of the buffer area 96 (pressure buffer means), or in addition to this, a pressure buffer device (2 nd pressure buffer means) such as an orifice or a tank may be provided at the fire extinguisher connection portion 94, the fire extinguishing agent pipe 20, the fire extinguishing agent supply port 32, or the like, and the pressure buffer device (2 nd pressure buffer means) may adjust the rise (or rate of rise) of the fire extinguishing agent supply pressure from the fire extinguisher 84 to a predetermined value or less (to such an extent that the fire extinguishing agent flow path 34 and the discharge port 30 are not broken). The cushion region 96 may be disposed below the sheet body 28(28c) to function as a weight (assist unit) when the sheet body 28(28c) is unfolded. Such a pressure buffer unit or 2 nd pressure buffer unit may be appropriately provided as necessary in the embodiment illustrated in fig. 1 to 14.
In the protective bay 10 shown in fig. 15, a fire detector 14 is provided as a fire detection device and is connected to a receiver 16. In the present embodiment, the fire alarm lamp 16a is provided near the installation location of the fire extinguisher 84, and when the receiver 16 receives the fire signal from the fire detector 14 and outputs a fire alarm, the fire alarm lamp 16a is turned on or blinks in accordance with a control signal from the receiver 16 in conjunction with the fire alarm, thereby indicating the installation location of the fire extinguisher 84 where a fire extinguishing operation (specifically, a bolt opening operation) is required or the fire extinguishing operation can be performed. Here, the fire extinguishing system of the present embodiment includes the fire extinguishing device 12, the fire extinguishing agent pipe 20, the fire extinguisher 84, and the fire extinguisher coupling portion 94.
In the fire extinguishing device 12 of the present embodiment, when a user performs a bolt opening operation, that is, pulls out the safety pin 90 of the fire extinguisher 84 disposed at a predetermined position outside the room as the protected area 10 and holds the handle 92, the fire extinguishing agent is supplied to the sheet body 28(28c) provided at the upper portion of the boundary portion (for example, the entrance or the exit) of the room as the protected area 10, and the fire extinguishing agent is spread out and is ejected in a planar manner from the plurality of ejection ports 30 disposed at each position of the sheet body 28(28c), thereby effectively extinguishing a fire in a short time.
Further, even if the user is unfamiliar with the operation of the fire extinguisher 84, the location where the fire extinguisher 84 is installed is located outside the room as the protected area 10, for example, and is far from the location where the fire occurs, so that the user can operate the fire extinguisher 84 without confusion and without much burden, and the unlatching operation of the fire extinguisher 84 can be performed quickly and reliably.
Further, the fire extinguishing agent is discharged from the fire extinguisher 84 in a short time, for example, in the order of tens of seconds, and when the fire extinguisher 84 is not extinguished even when the fire is exhausted, the fire extinguisher nozzle 94a is removed from the fire extinguisher connection port 94b of the fire extinguisher connection portion 94 and replaced with an unused fire extinguisher 84 prepared separately in advance (the fire extinguisher nozzle 94a prepared separately is attached to the hose 86 in advance), whereby the fire extinguishing agent can be continuously discharged and the fire can be reliably extinguished. Further, it is also possible to provide fire extinguisher coupling portions to which a plurality of fire extinguishers can be connected, or to provide fire extinguisher coupling portions at a plurality of locations in the fire extinguishing agent pipe and connect a plurality of fire extinguishers to the fire extinguishing agent pipe 20 in advance, thereby enabling continuous injection of the fire extinguishing agent without replacing a used fire extinguisher.
Further, when a fire breaks out in a place different from the protected area 10 (a place where the fire extinguishing apparatus 12 of the present embodiment is not installed), the fire extinguisher 84 can be removed from the fire extinguishing agent pipe 20 and transported to the place where the fire breaks out for use, so that there is no need to increase the number of fire extinguishers installed, and an increase in maintenance and management costs is suppressed.
[ F. fire extinguishing facility combining fire extinguisher and water supply piping ]
As shown in fig. 18, the present embodiment is characterized in that the fire extinguishing agent supply source of the fire extinguishing device 12 installed at the upper portion of the boundary portion (e.g., entrance or exit) of the room as the protective area 10 is a combination of a fire extinguisher 84 and a water pipe 18, the fire extinguisher 84 supplies, for example, a dry powder fire extinguishing agent or a fire extinguishing agent with a reinforcing liquid as a fire extinguishing agent, and the water pipe 18 supplies water as a fire extinguishing agent.
One end of the fire extinguishing agent pipe 10 is connected to a fire extinguishing agent supply port 32 of the sheet body 28(28c), and the other end is connected to the tap water pipe 18 via a remote on-off valve 24 and a manual on-off valve 26, which are connected in parallel as a pipe opening and closing means for opening and closing a pipe flow path by remote control or manual operation.
Further, a fire extinguisher 84 is connected to a pipe branching from a portion between one end side of the fire extinguishing agent pipe 20 and the remote on-off valve 24 and the manual on-off valve 26 (point a in the drawing) via a check valve 98 as a backflow prevention means for preventing backflow of tap water from the fire extinguishing agent pipe 20 side to the fire extinguisher 84 side, and a fire extinguisher connection portion 94 as a connection means for detachably connecting the fire extinguisher 84 to the fire extinguisher pipe 20 is provided. The fire extinguisher coupling portion 94 has a fire extinguisher nozzle 94a and a fire extinguisher connection port 94b, and adopts, for example, a coupling joint structure similar to that shown in fig. 16.
A fire detector 14 is provided as fire detection equipment in the protective bay 10 and is connected to a receiver 16. An alarm display lamp 16a is provided near the location where the fire extinguisher 84 is installed, and is connected to the receiver 16. The fire alarm lamp 16a is a display unit as follows: when the receiver 16 receives the fire signal from the fire detector 14 and outputs a fire alarm, the fire alarm lamp 16a receives a control signal from the receiver 16 in conjunction with the fire alarm, lights up or blinks, and displays an indication of the installation location of the fire extinguisher 84 where a fire extinguishing operation is required or possible. The receiver 16 is connected to the control line of a remote on-off valve 24. Here, the fire extinguishing system of the present embodiment includes the fire extinguishing device 12, the fire extinguishing agent pipe 20, the fire extinguisher 84, the fire extinguisher connecting portion 94, the check valve 98, the remote opening/closing valve 24, the manual opening/closing valve 26, and the water pipe 18.
The receiver 16 can set, for example, an automatic fire extinguishing mode and a manual fire extinguishing mode. The automatic fire extinguishing mode is set in a time zone such as nighttime, for example, and the fire extinguishing agent is discharged by the remote on-off valve 24 based on the opening control of the control signal (opening control signal) from the receiver 16 in conjunction with the fire detection by the fire detector 14 (fire alarm of the receiver). The manual fire extinguishing mode is set, for example, in a daytime, and the fire extinguishing agent is discharged by a bolt opening operation of the fire extinguisher 84 or an opening operation of the manual on-off valve 26. Further, in addition to the manual fire extinguishing mode/automatic fire extinguishing mode being switched in accordance with the time period of day/night in this way, the manual fire extinguishing mode/automatic fire extinguishing mode may be switched depending on presence/absence of a person, or they may be combined.
When a fire occurs in the protective bay 10 while the manual fire extinguishing mode is set in the receiver 16, the receiver 16 outputs a fire alarm upon receiving a fire signal from the fire detector 14, and lights or blinks an alarm display lamp 16a provided corresponding to the protective bay 10 in which the fire has occurred.
When it is confirmed that a person who knows that a fire has occurred travels to the protected area 10, the safety pin 90 of the fire extinguisher 84 is removed and the handle 92 is pressed to open the fire extinguisher 84, and the fire extinguishing agent is supplied from the fire extinguisher 84 to the fire extinguishing device 12, whereby the sheet body 28(28c) is spread and the dry chemical agent or the like is discharged in a planar manner from the plurality of discharge ports 30 disposed at each position of the sheet body 28(28c) to extinguish the fire.
When the extinguishing agent from the fire extinguisher 84 is discharged to the maximum extent, the manual on-off valve 26 is opened to supply tap water to the fire extinguishing device 12, and tap water is discharged in a planar manner from the plurality of discharge ports 30 disposed at each position of the spread sheet body 28(28c) to extinguish the fire. Since the discharge of tap water is performed after the fire is suppressed by discharging the fire extinguishing agent from the fire extinguisher 84, and the discharge of tap water is not time-limited, the fire can be reliably extinguished.
On the other hand, when the automatic fire extinguishing mode is set in the receiver 16, the receiver 16 that has received the fire signal from the fire detector 14 sends an open control signal to the remote on-off valve 24 to open the valve, and supplies tap water to the fire extinguishing device 12, thereby spreading the sheet body 28(28c), and discharging tap water from the plurality of discharge ports 30 disposed at each position of the sheet body 28(28c) in a planar manner to extinguish the fire.
In the automatic fire extinguishing mode, for example, when the person concerned who has gone away after receiving the fire notification knows that the fire has not declined, the receiver 16 may perform a predetermined operation of closing the remote on-off valve 24 (for example, an operation of releasing the automatic fire extinguishing mode and setting the automatic fire extinguishing mode to the manual fire extinguishing mode), and then remove the safety pin 90 of the fire extinguisher 84 and press the handle 92 to cock the fire extinguisher 84, supply the fire extinguishing agent from the fire extinguisher 84 to the fire extinguishing device 12, and eject the fire extinguishing agent in a planar manner from the plurality of ejection ports 30 disposed at each position of the spread sheet body 28(28c) to extinguish the fire.
After the fire extinguishing agent is discharged from the fire extinguisher 84 in this manner, the manual on-off valve 26 may be opened again to switch to discharge tap water again.
[ G. fire extinguishing apparatus fixedly provided with sheet body ]
As shown in fig. 19, the present embodiment is characterized in that the sheet member 28 of the fire extinguishing device 12 is fixedly installed in the protection area 10 in a spread state.
The fire extinguishing device 12 of the present embodiment includes a mounting portion 12a and a sheet member 28, and one end edge of the sheet member 28 is fixed to the mounting portion 12 a. In the fire extinguishing equipment 12, for example, the mounting portion 12a is fixed to an upper portion of a predetermined wall surface of a room as the protective partition 10, the sheet member 28 having one end fixed to the mounting portion 12a is lowered along the wall surface, and the sheet member 28 is fixed to the wall surface by rivets or the like to such an extent that it does not rattle. The structure other than this is the same as the embodiment of fig. 1.
According to the present embodiment, the sheet spreading structure shown in fig. 13 is not necessary, and therefore, the structure is simple and the cost can be reduced.
Fig. 20 shows another embodiment of the fire extinguishing device 12 in which the sheet member is fixedly installed, and the fire extinguishing device 12 of the present embodiment includes the mounting portion 12a and the sheet member 28 (linear sheet member 28d), and the plurality of discharge ports 30 are arranged in a straight line in the sheet member 28(28 d). The sheet body 28(28d) can be produced by the same method as that shown in fig. 6 or 9. The fire extinguishing agent pipe 20 is connected to the sheet body 28(28d), and when a fire breaks out, the receiver 16 opens the remote opening/closing valve 24 or opens the manual opening/closing valve 26, thereby supplying tap water as the fire extinguishing agent, and the fire extinguishing agent is discharged from the discharge port 30 provided in the sheet body 28(28d) to extinguish the fire.
The sheet body 28(28d) of the present embodiment has the discharge port array elements formed by arranging the discharge ports 30 as the discharge points on a straight line in the lateral direction to form the entire discharge port array, and thus extinguishes the fire by discharging the fire extinguishing agent in a line discharge manner. The sheet body 28(28d) may be disposed in the vertical direction (longitudinal direction) or may be disposed in an oblique direction.
Further, although the fire extinguishing device 12 shown in fig. 19 and 20 is exemplified by using tap water as a fire extinguishing agent, the fire extinguisher 84 shown in fig. 15 may be used as a fire extinguishing agent supply source, or the fire extinguisher 84 and tap water may be combined as shown in fig. 18. In this case, a pressure buffer device (2 nd pressure buffer means) may be provided at the fire extinguisher connection portion 94, the fire extinguishing agent pipe 20, the fire extinguishing agent supply port 32, and the like between the fire extinguisher 48 and the linear sheet member 28(28d), and the pressure buffer device (2 nd pressure buffer means) may adjust the rise of the fire extinguishing agent supply pressure from the fire extinguisher 48 to a predetermined value or less.
Further, the surface discharge of the fire extinguishing agent may be obtained by the plurality of sheet members 28(28 d). For example, by arranging the plurality of sheet bodies 28(28d) in parallel on the same surface, the fire extinguishing agent can be discharged in a surface discharge manner as a whole.
[ H. modification of the present embodiment ]
A modification of the present embodiment will be described in detail.
(arrangement of ejection ports of sheet body)
In the above embodiment, the plurality of ejection ports 30 are arranged at each position on one surface of the sheet 28, but the present invention is not limited thereto, and the plurality of ejection ports 30 may be arranged at each position on both surfaces of the sheet 28. The sheet material 28 having the plurality of discharge ports 30 arranged at each of both surfaces is fire-extinguished by arranging the fire extinguishing device 12 at a ceiling portion or the like at the center of a room as the protected area 10, spreading the sheet material 28 from the upper side to the lower side in the event of a fire, and discharging the fire extinguishing agent in a planar manner from the plurality of discharge ports 30 at each of both surfaces of the sheet material to both sides.
(protective zoning)
In the above embodiment, the room of a cognizant aged person who faces elderly people is taken as an example as the protective bay, but in the case of a room of a general house or an apartment house, for example, a wireless-linkage type house fire alarm device may be used instead of the fire detector 14 and the receiver 16, the remote open/close valve 24 may be connected to a wireless-linkage type adapter that receives a fire linkage signal from the house fire alarm device and outputs a contact signal, and the remote open/close valve 24 may be driven to open by the contact signal when a fire occurs, and the fire extinguishing agent may be ejected in a planar manner from the plurality of ejection ports 30 disposed at each position of the sheet body 28.
Further, the application object of the fire extinguishing apparatus of the present invention can be applied to, for example, factories, schools, institutions, and other appropriate facilities. Of course, the protective zoning is not limited to rooms, and suitable zoning may be employed.
(fire extinguishing agent flow path)

[ Portable fire extinguishing apparatus ]
Next, embodiments of the portable fire extinguishing apparatus according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiments.
[ basic concept of embodiment ]
Embodiments generally relate to a portable fire suppression apparatus for a user to cover a fire source to extinguish a fire. Here, the "fire extinguishing device" refers to a device for extinguishing a fire by spraying or sprinkling a fire extinguishing agent, and the fire extinguishing device of the present embodiment includes a sheet body, a fire extinguishing agent flow path, a fire extinguishing agent supply port, and a discharge port.
The "sheet body" is a concept as follows: the nozzle has a thin (thick) nozzle having flexibility on one surface, and has a desired size, and can be used for covering or covering, for example, a cloth-like body which can be stored in a non-expanded state and put into an expanded state when used (when a fire is extinguished). Here, the "one surface of the sheet body" refers to a surface facing downward (a surface facing the fire source) when the user covers the sheet body on the fire source, and refers to a surface having a function of ejecting the fire extinguishing agent.
The sheet body is not spread in a normal state, and is spread over the fire source in a fire extinguishing state. In addition, in a normal case, the sheet member is disposed in the vicinity of the fire extinguishing target and is in an undeployed state, for example, stored in a storage unit or hung on a rack unit, and when a fire breaks out, the user takes out and unfolds the sheet member quickly to cover the fire source and eject the fire extinguishing agent from one surface of the sheet member.
In addition, the "fire extinguishing agent flow path" is a concept as follows: the channel through which the fire extinguishing agent flows is provided in the sheet body, and includes, for example, a sheet pipe disposed between the cloth bodies. The "sheet pipe" is, for example, a flexible pipe that can be crushed and deformed freely and that expands when the fire extinguishing agent flows therethrough.
In addition, the "fire extinguishing agent supply port" is a concept as follows: the inlet for supplying the fire extinguishing agent to the fire extinguishing agent flow path provided in the sheet body includes, for example, a connection port of a fire extinguishing agent pipe.
The "discharge port" is an outlet of the fire extinguishing agent supplied from the fire extinguishing agent supply port to the fire extinguishing agent flow path, and is an opening through which the fire extinguishing agent is discharged from each of the plurality of discharge ports disposed at each of the one surface of the sheet body.
In addition, the "fire extinguishing agent pipe" is a concept as follows: the flexible piping is a flexible piping for supplying the fire extinguishing agent to the fire extinguishing agent flow path of the sheet body, and includes, for example, a hose made of rubber or synthetic resin for supplying the fire extinguishing agent to the fire extinguishing device.
In addition, the "fire extinguishing agent supplying equipment" is a concept as follows: when a user performs a predetermined operation, the fire extinguishing agent is supplied to the fire extinguishing agent pipe, and the fire extinguishing agent pipe includes a fire extinguisher that supplies a fire extinguishing agent such as a liquid fire extinguishing agent, a fire extinguishing enhancing liquid, or a dry powder fire extinguishing agent.
In the fire extinguishing device according to the embodiment, when the sheet member is covered with the fire source so that one surface of the sheet member faces the fire source side and the fire extinguishing agent supplying device is operated in a predetermined manner, the fire extinguishing agent supplied from the fire extinguishing agent supplying device to the fire extinguishing agent flow path through the fire extinguishing agent pipe is discharged from the discharge port on the one surface.
In the following description, specific contents of the embodiment of the fire extinguishing device will be described with respect to a case where "fire source" is "indoor equipment or equipment" and "fire extinguishing agent supplying device" is "fire extinguisher".

[ A. outline of fire extinguishing apparatus ]
As shown in fig. 21, the fire extinguisher 100 of the present embodiment includes a sheet body 112, a fire extinguishing agent supply hose 126, and a fire extinguisher 84, and the fire extinguishing agent supply hose 126 functions as a fire extinguishing agent pipe.
[ b. sheet Material ]
The sheet member 112 discharges the fire extinguishing agent to extinguish a fire in a state of covering the fire source, and has any structure and structure, and includes, for example, a fire extinguishing agent flow path 34, a fire extinguishing agent supply port 32, and a discharge port 30.
The sheet body 112 is, for example, a flexible cloth-like body, and as shown in fig. 21 a, fire extinguishing is performed by spraying the fire extinguishing agent from one surface 112a in a state where the sheet body 112 is covered on the fire source with the one surface 112a facing the fire source (the one surface 112a side facing the fire source).
The sheet body 112 is a rectangular sheet body having a longitudinal and transverse length corresponding to an object of fire suppression, including a gas range, a heating appliance, and other devices, equipment, places, and the like that may be a fire source installed in a residence or the like, for example, a square sheet body, and the sheet body 112 has flexibility, and thus can be folded to be in a non-unfolded state in a normal time when not in use, and can be unfolded to be in an unfolded state for use in a time of fire suppression.
Here, in the illustrated developed state, the sheet member 112 has a vertical direction as a vertical direction, a lateral direction as a horizontal direction, and a depth direction toward the paper surface as a thickness direction shown in fig. 21 (B). The longitudinal direction and the lateral direction are directions relatively determined when the sheet body 112 in the developed state is viewed from an arbitrary direction.
(b1. fire extinguishing agent flow path and fire extinguishing agent supply port)
The fire extinguishing agent flow path 34 is a passage for flowing the fire extinguishing agent provided in the sheet body 112, and has an arbitrary structure and structure, and for example, the fire extinguishing agent supply port 32 is disposed at one end side (illustrated lower end side) of the sheet body 112, the buffer region 96 serving as pressure buffering means indicated by a broken line is provided inside the sheet body 112 following the fire extinguishing agent supply port 32, and the fire extinguishing agent flow path 34 is provided following the buffer region 96, and the fire extinguishing agent flow path 34 has a plurality of discharge ports 30 disposed at each position of the one surface 112 a.
The fire extinguishing agent flow path 34 is formed in a ladder shape having, for example, 5 stages in the vertical direction, a buffer area 96 having the fire extinguishing agent supply port 32 is provided at the center of the 1 st stage which is the lowest stage, and 4 discharge ports 30 are arranged from the 2 nd to 5 th stages from the bottom, for example.
The fire extinguishing agent flow path 34 is formed to supply the fire extinguishing agent from both sides of the row of discharge ports to the transverse row of discharge ports 30 arranged from the 2 nd stage to the 5 th stage from the bottom.
The form of the fire extinguishing agent flow path 34 for supplying the fire extinguishing agent to the plurality of discharge ports 30 is not limited to the ladder shape shown in the figure, and may include a tree shape, a championship tree shape, and other suitable forms. In order to make the discharge pressures of the plurality of discharge ports 30 substantially uniform, the thickness (cross-sectional area) of the fire extinguishing agent flow path 34 may be made large on the fire extinguishing agent supply port 32 side and may be made small as it is farther from the fire extinguishing agent supply port 32. The number and arrangement of the discharge ports 30 provided corresponding to the fire extinguishing agent flow path 34 are arbitrary.
(b2. spout)
The discharge port 30 is an outlet of the fire extinguishing agent supplied from the fire extinguishing agent supply port 32 to the fire extinguishing agent flow path 34, and is arbitrary in structure and structure, and as shown in fig. 21 (B), for example, the discharge port 30 is opened on one surface 112a of the sheet body 112, and the fire extinguishing agent supplied from the fire extinguishing agent supply port 32 to the fire extinguishing agent flow path 34 is discharged from each part of the one surface 112a of the sheet body 112 to extinguish the fire.
The sheet body 112 covers the fire source with the one surface 112a facing downward (toward the fire source side), and at this time, the sheet surface opposite to the one surface 112a becomes the other surface 112b exposed to the outside.
[ fire extinguishing agent piping ]
The fire extinguishing agent pipe is a flexible pipe for supplying the fire extinguishing agent to the fire extinguishing agent flow path 34 of the sheet body 112, and is of any structure, and kind, and is provided with a fire extinguishing agent supply hose 126, for example, the fire extinguishing agent supply hose 126 is a flexible hose made of rubber or synthetic resin.
[ fire extinguishing agent supply device ]
The fire extinguishing agent supply device is configured to supply the fire extinguishing agent to the fire extinguishing agent supply hose 126 provided as a fire extinguishing agent pipe when a user performs a predetermined operation, and the fire extinguishing agent supply device may have any structure, function, and type, and is connected to one end of the fire extinguishing agent supply hose 126 using, for example, the fire extinguisher 84. The extinguisher 84 is filled with a prescribed fire extinguishing agent (such as a dry powder fire extinguishing agent or a fire extinguishing agent of a fire-extinguishing-intensifying liquid) in a pressure-accumulating state in the main body container, and when the user pulls off the safety pin 90 and presses the handle 92, the extinguisher 84 is unlatched to supply the fire extinguishing agent to the extinguisher hose 86.
Regarding the connection between the sheet body 112 and the fire extinguisher 84, one end of a fire extinguishing agent supply hose 126 is connected to the fire extinguishing agent supply port 32 of the sheet body 112, and the other end of the fire extinguishing agent supply hose 126 is connected to a fire extinguisher nozzle 94a at the tip end of the fire extinguisher hose 86 of the fire extinguisher 84 via a fire extinguisher coupling portion 94.
The fire extinguisher coupling section 94 as the coupling means has a fire extinguisher nozzle 94a and a fire extinguisher connection port 94b, and uses a known coupling joint similar to a coupling joint for detachably connecting a hose to a faucet by a one-touch operation, for example. Here, the fire extinguisher nozzle 94a is not limited to a configuration in which a nozzle attached to the hose end of the fire extinguisher 84 in advance is removed and a fire extinguisher nozzle 94a prepared separately is attached in advance. The details of the fire extinguisher coupler 94 are the same as those shown in fig. 16.
The fire extinguishing agent flow path 34 has a buffer area 96 as a pressure buffer means on the inlet side, and the fire extinguishing agent from the fire extinguisher 84 is temporarily retained to make the rise (or rate of rise) of the fire extinguishing agent pressure a predetermined value or less in an initial stage after the start of the supply of the fire extinguishing agent, thereby preventing the fire extinguishing agent flow path 34 and the discharge port 30 from being damaged.
In addition, instead of the buffer area 96 (pressure buffer means), or in addition to this, a pressure buffer device (2 nd pressure buffer means) such as an orifice may be provided at the fire extinguisher connection portion 94, the fire extinguishing agent supply hose 126, the fire extinguishing agent supply port 32, or the like, and the pressure buffer device (2 nd pressure buffer means) may adjust the rise (or rate of rise) of the fire extinguishing agent pressure from the fire extinguisher 84 to a predetermined value or less (to such an extent that the fire extinguishing agent flow path 34 and the discharge port 30 are not broken).
[ e. method 1 for producing sheet Material ]
The sheet body 112 of the present embodiment shown in fig. 21 is produced by the method shown in fig. 22, for example. The sheet body 112 of the present embodiment has the same structure as the sheet body 28(28a) shown in fig. 6, except that the weight 122 is provided. First, the 1 st cover sheet 36 and the 2 nd cover sheet 38 having a predetermined size are prepared. The illustrated upper surface of the 1 st covering sheet 36 becomes one surface 112a of fig. 21 when the sheet body 112 covers the fire source, and the illustrated lower surface of the 2 nd covering sheet 38 becomes the other surface 112B of fig. 21 (B) when the sheet body 112 covers the fire source. In addition, the two sheets are illustrated in a horizontally arranged state.
The 1 st cover sheet 36 and the 2 nd cover sheet 38 are, for example, cloth-like bodies having fire-proof, fire-resistant, heat-resistant, or flame-retardant properties, and can withstand high heat of 1200 ℃.
The 1 st cover sheet 36 and the 2 nd cover sheet 38 also have heat insulating properties, flame retarding properties, smoke retarding properties, and the like. The second covering sheet 38 whose lower surface is the other surface 12b may be a normal cloth having no fire resistance, heat resistance, flame retardancy, heat insulation, flame retardancy, or smoke retardancy.
Next, the plurality of weights 122 are arranged along the outer peripheral edge of the 2 nd covering sheet 38 at intervals, and the weights 122 are fixed along the sheet outer peripheral edge by, for example, folding inward and bonding the protruding portions 38a formed on the outer peripheral edge.
The weight 122 is, for example, a member such as lead having a predetermined length, and when the user spreads the sheet body 112 and throws it to cover the fire source, the sheet body 112 can be spread and thrown by the weight 122 on the outer peripheral edge like a net throwing, and the fire source can be easily covered in the spread state of the sheet body 112.
Further, when the sheet body 112 is spread to the fire source, the weight 122 presses the outer peripheral edge, whereby the rising of the sheet body 112 due to the ejection of the fire extinguishing agent is suppressed, the fire extinguishing agent is suppressed from leaking and scattering from the fire source covered with the sheet body 112, the fire extinguishing effect is improved, and the contamination of the periphery is reduced.
Next, 5-stage ladder-shaped sheet pipes 40 are prepared. The sheet pipe 40 is obtained by, for example, forming a cloth-like body such as polyester for umbrella production into a tubular shape and connecting the tubular shape into a ladder shape (a connecting portion for circulation). The sheet pipe 40 is crushable and deformable, and is crushed and flattened at normal times, and when the fire extinguishing agent 41 is supplied, the sheet pipe 40 expands to form the fire extinguishing agent flow path 34. The buffer area 96 provided next to the fire extinguishing agent supply port 32 is also flattened by being crushed in a normal state, and expands to form the buffer area 96 when the fire extinguishing agent is supplied.
Further, a plurality of discharge ports 30 are arranged in sheet pipes 40 of 2 nd to 5 th stages after the 1 st stage where the buffer area 96 is provided, and through holes 56 are opened in the 1 st covering sheet 36 corresponding to the discharge ports 30. The ejection port 30 has the same structure as that shown in fig. 8.
[ f. method 2 for producing sheet Material ]
Fig. 23 shows another method of manufacturing the sheet body 112. The sheet body 112 of the present embodiment has the same configuration as the sheet body 28(28b) shown in fig. 9, except that the weight 122 is provided. First, the 1 st covering sheet 36, the 1 st waterproof sheet 52, the 2 nd waterproof sheet 54, and the 2 nd covering sheet 38 having predetermined sizes are prepared. In addition, each sheet is illustrated in a state of being horizontally arranged.
The 1 st cover sheet 36 and the 2 nd cover sheet 38 are produced in the same manner as in fig. 22, and the 1 st waterproof sheet 52 and the 2 nd waterproof sheet 54 are made of, for example, a cloth-like material such as polyester used for umbrella production. The second covering sheet 38 whose lower surface is the other surface 12b may be a normal cloth having no fire-proof, fire-resistant, heat-resistant, or flame-retardant properties.
The 1 st waterproof sheet 52 is provided with the fire extinguishing agent supply port 32 corresponding to the fire extinguishing agent flow path 34 to be formed, the through hole 58 corresponding to the discharge port 30 to be fixed, and the through hole 56 formed in the 1 st covering sheet 36. Further, similarly to the manufacturing method of fig. 22, a weight 122 is fixed to the outer peripheral edge of the 2 nd covering sheet 38.
In a state where through holes 56 and 58 of the 1 st covering sheet 36 and the 1 st waterproof sheet 56 are aligned and overlapped, the ejection port 30 is attached in the same manner as shown in fig. 10.
Next, the 2 nd waterproof sheet 54 and the 2 nd waterproof sheet 38 are superimposed in a state where the 1 st covering sheet 36 and the 1 st waterproof sheet 52 are fixed through the ejection outlet 30. In this state, as shown in fig. 24, for example, a sewing operation is performed using a waterproof thread by a sewing machine or the like to form a sewn portion 60, thereby producing a cushioning region 96 and an extinguishing agent flow path 34. In addition, in a state where the sheets are stacked, the sewn portion 61 is obtained by sewing along the outer peripheral edge of the sheets except for the portion of the weight 122, and the sewn portion 61 is integrated to form the sheet body 112.
[ configuration and use of fire extinguishing apparatus ]
Next, the arrangement of the fire extinguishing apparatus according to the present embodiment in a normal state and the use thereof in the case of a fire will be described in detail.
For example, as shown in fig. 25 (a), when a sofa 130 placed in a smoking site or the like is to be put out a fire, the fire extinguishing device 100 of the present embodiment is disposed in a state in which the sheet body 112 is hung on the holder 128 provided near the sofa 130.
As shown in fig. 26 (a), for example, the holder 128 has a rod 138 standing on a pedestal 136, a hemispherical attachment piece 140 at the tip of the rod 138, a hose holder 142 in the middle of the rod 138, and a fire extinguisher holder 144 on a pedestal 1136.
As shown in fig. 26 (B), the installation mode of the fire extinguishing device 100 is such that the sheet member 112 is suspended with the sheet member 112 suspended from the sheet member 112 by the substantially central portion of the sheet member 112 being the inside of the one surface 112a of the sheet member 112 being the hanging sheet member portion 1144 at the tip end of the rod 138, the sheet member 112 is in a state such as a closed umbrella, the fire extinguisher 84 is disposed on the fire extinguisher holder 144 of the pedestal 136, the fire extinguishing agent supply hose 126 is hung on the hose holder 142 in a wound state, and the user can easily take off the sheet member 112 from the holder 128 and use it in the event of a fire.
As shown in fig. 25 (B), when a fire such as the fire source 132 occurs in the sofa 130 due to the remaining fire of smoking, the user 134 removes the sheet body 112 of the fire extinguishing apparatus 100 hung on the bracket 128 and spreads it so that one surface 112a thereof covers the fire source of the sofa 130 shown in the fire source 132 downward. In this case, since the weight is disposed on the outer peripheral edge of the sheet body 112, the sheet body 112 can be thrown while being spread like a net, and the fire source of the sofa 130 can be covered easily and reliably.
Next, as shown in fig. 25 (C), when the user 134 performs a fire-extinguishing operation, that is, removes the safety pin 90 shown in fig. 26 (B) of the fire extinguisher 84 disposed on the holder 128 and presses the handle 92, the fire extinguishing agent is supplied from the fire extinguisher 84 to the sheet body 112 via the fire extinguishing agent supply hose 126, and the fire extinguishing agent is discharged in a planar shape from the discharge ports disposed at the respective positions of the lower surface 112a of the sheet body 112, whereby the fire extinguishing agent spreads over the fire source covered with the sheet body 112 without fail, and a fire can be effectively extinguished in a short time.
At this time, although the sheet body 112 is intended to float from a state covering the fire source due to the discharge pressure of the fire extinguishing agent, the floating of the sheet body 112 is suppressed by the operation of the weight disposed on the outer peripheral edge, and the sheet body 112 is not curled or flown. Further, since the fire extinguishing agent is discharged in the process of being covered with the sheet body 112, the fire extinguishing agent can be suppressed from leaking and scattering to the surroundings, and contamination of the surroundings can be reduced in addition to fire extinguishing.
Further, the fire extinguishing agent is discharged from the fire extinguisher 84 in a short time, for example, in the order of tens of seconds, and when the fire extinguisher 84 is not extinguished even when the fire is exhausted, the user 134 removes the fire extinguisher nozzle 30 from the fire extinguisher connection port 32 of the fire extinguisher connection portion 94 shown in fig. 21 and replaces the exhausted fire extinguisher 84 with an unused fire extinguisher 84 prepared separately in advance (the fire extinguisher nozzle 94a prepared separately is mounted in advance on the fire extinguisher hose 86), whereby the fire extinguishing agent can be continuously discharged and the fire can be reliably extinguished.
In addition, when a fire breaks out in another place where the fire extinguishing apparatus 100 of the present embodiment is not installed, the user 134 can remove the fire extinguisher 84 from the fire extinguishing agent supply hose 126 and transport it to the fire source for use, and therefore, there is no need to increase the number of installed fire extinguishers, and it is possible to suppress an increase in maintenance and management costs. Further, casters and the like may be provided on the base 136 of the bracket 128 shown in fig. 26 as a carriage, and the fire extinguisher 100 may be configured to be movable so as to be moved to a fire source for use.
[ arrangement of fire extinguishing apparatus in normal conditions ]
(h1. storage case)
The installation mode of the fire extinguishing apparatus 100 in a normal state may be an installation mode using the housing case 146 shown in fig. 27, in addition to the installation mode using the bracket 128 shown in fig. 26.
The housing case 146 shown in fig. 27 is provided with a case cover 150 that can be opened and closed on a case main body 148, and the case main body 148 houses the folded sheet member 112, the fire extinguishing agent supply hose 126 in a wound state, and the fire extinguisher 84.
When extinguishing a fire, the user 134 opens the case cover 150 as shown by the case cover 150a, takes out the folded sheet body 112, and spreads it to cover the fire source with one surface 112a facing downward. Next, the fire extinguisher 84 exposed to the outside is subjected to a fire extinguishing operation, whereby the fire extinguishing agent is supplied to the sheet body 112 through the fire extinguishing agent supply hose 126, and the fire extinguishing agent is discharged in a planar manner from the discharge ports at the respective positions of the one surface 112a of the sheet body 112 toward the covered fire source to extinguish the fire. Further, the fire extinguishing device 100 may be configured to be movable by providing casters or the like as a carriage on the housing main body 148 so as to be movable to a fire source for use.
(h2. folding of sheet Material body)
As shown in fig. 28, the sheet body 112 may be folded into a bag shape and hung on the stand 128 shown in fig. 26 or stored in the storage case 146 shown in fig. 27.
The structure and method for folding the sheet body 112 into a handbag-like state are arbitrary, and for example, as shown in fig. 28 (a), in a state where the sheet body 112 is unfolded, a handle 152 and a fixing band 154 are provided on the other surface 112b of the sheet body 112. Here, the fold of the sheet body 112 is shown by a one-dot chain line, and the sheet body 112 can be folded into, for example, 1/12 size as shown in fig. 28 (a) to (D) by dividing the sheet body into vertical and horizontal parts 12.
As shown in fig. 28 (a) to (D), the fixing band 154 includes a hook member 156 provided on the fixing band 154 and a hook base member 158 provided at a predetermined position on the other surface 112b, which together constitute a holding means for releasably holding the sheet body 112 in a predetermined folded state obtained by folding the sheet body 112a plurality of times with a single-dot chain line passing through the fixing position of the handle 152 as an initial fold line.
In detail, the handle 152 is formed in a half-moon shape by fixing both ends of the handle 152 to the center portion along the first fold line (the central lateral fold line in the figure) of the other surface 112 b. The proximal end (one end) of the fixing band 154 is fixed to the sheet surface between the fixing portions at both ends of the handle 152, and the distal end (the other end) can pass through the handle 152 and be positioned on the opposite side.
For example, a hook member 156 is provided on the distal end side of the fixing band 154, and a hook female member 158 is provided at a predetermined position on the other surface 112b in accordance with the hook member. As shown in fig. 28 (D), the hook member 156 is provided at a predetermined position where it can be locked to the hook member 158 of the fixing tape 154 in a state where the sheet body 112 is folded to be small.
In the folding method of the sheet body 112, first, the sheet body is folded in two from the top to the bottom in the state shown in fig. 28 (a), and is folded into an 1/2-sized folded state shown in fig. 28 (B). Next, the left side of the sheet body 112 folded into 1/2 size is folded from the front to the center, and the right side is folded from the front to the center in an overlapping manner, thereby forming a folded state of 1/6 size shown in fig. 28 (C).
Next, the lower side of the sheet body 112 folded into 1/6 size is folded from the front to the upper side so that the hooking base 158 comes to the front, and a folded state of 1/12 size shown in fig. 28 (D) is obtained, and finally, the hooking base 156 of the fixing tape 154 passing through the inside of the handle 152 is locked to the hooking base 158 to maintain the folded state.
Thus, for example, if the sheet body 112 has a longitudinal and lateral dimension of 150 cm, it can be folded to a dimension (area 1/12) of approximately 37.5 cm in the longitudinal direction and 50 cm in the lateral direction, and the installation space in a normal state can be reduced. In addition, the sheet body 112 is preferably folded in a reasonable range (a range where the sheet body piping 40 and the ejection port 30 are not damaged by folding) in a minimum size.
In addition, at the time of fire extinguishing, the user takes out the sheet body 112 in a folded state with the handle 152 being held, spreads the sheet body 112 by unfastening the fastening band 154, and covers the fire source with one surface 112a facing downward. In this case, the sheet member 112 can be easily and safely covered with the fire source by holding the handle 152.
[ i. arrangement in a normal state in which a sheet body is covered on a fire extinguishing object ]
As another example of the normal arrangement of the present embodiment, as shown in fig. 29, the following state may be adopted: the sheet body 112 of the fire extinguishing device 100 is covered with a predetermined fire extinguishing object, for example, furniture such as a bed 160 on which bedding 162 including an electric blanket is placed, with one surface 112a facing downward.
In this case, the sheet body 112 is sized to cover the bed 160 sufficiently. The fire extinguisher 84 is disposed in the vicinity of the bed 160 as a fire extinguishing target or outside the room in which the bed 160 is placed, and the fire extinguisher 84 is connected to the fire extinguishing agent supply port 32 of the sheet body 112 through the fire extinguishing agent supply hose 126 via the fire extinguisher connection portion 94.
In the present embodiment, when the bed 160 to be extinguished is on fire, the user can quickly extinguish the fire by simply performing a bolt-opening operation on the fire extinguisher 84 without performing an operation of spreading the sheet body 112 and covering the fire source by the user.
