For example, water that discharges water in the form of a shower, a mist that forms a flat surface, a jet that gives water, or the like can be employed. The water discharger 110 is supported so as to be swingable with respect to the vertical M at a rotating portion 113 which is a support position on the tubular portion 111 separated from the nozzle portion 112.

<Storage unit 120>
In the present embodiment, the storage unit 120 is a recess provided in the vertical M, and has a length and a width that allow the water discharger 110 to be stored in the recess. Further, a rotating portion 113 of the water discharger 110 is provided on the one end side above the storage portion 120. The water discharger 110 swings around the rotating portion 113 as a shaft, so that the nozzle portion 112 shown in FIG. It is swingable between the second positions separated from each other.

  In FIG. 2, the state in which the water discharger 110 is stored in the storage unit 120 is indicated by a solid line in the drawing, and the state in which the water discharger 110 is deployed is indicated by a dotted line in the drawing. Moreover, the supply apparatus 130 and the control apparatus 140 which supply water to the water discharger 110 and control water discharge are shown by FIG.

  Referring to FIG. 2, when discharging water, water discharger 110 swings and expands in the direction indicated by the arrow in the drawing due to the water pressure of water supplied from supply device 130 (dotted line in the drawing). The water discharger 110 includes a supply bellows portion 114 that supplies water into the tubular portion 111 adjacent to the rotating portion 113. The supply bellows portion 114 is connected to the supply device 130.

<Supply device 130>
The supply device 130 includes a supply pipe 131 connected to the supply bellows portion 114 of the water discharger 110, a pump 132 that applies pressure to water from a water source (not shown), and an open / close that opens and closes communication between the pump 132 and the supply pipe 131. And a valve 133.

  The supply pipe 131 is disposed inside the building BL so as to supply water to each of the plurality of water dischargers 110 installed. At least one pump 132 may be provided to supply water pressure to the plurality of water dischargers 110, but a plurality of pumps 132 may be provided depending on the number of water dischargers 110 and the operation of the water dischargers 110. For example, when the water discharger 110 is provided on each floor of the building BL, if it is desired to control the water discharge of the water discharger 110 on each floor, a pump can be provided on each floor according to the capacity of the pump 132. Similar to the pump 132, a plurality of on-off valves 133 can be provided according to the number and operation of the water dischargers 110.

<Control device 140>
The control device 140 controls driving of the pump 132 and the on-off valve 133. FIG. 3 shows a block diagram of the control device 140. The control device 140 includes a processing unit 141, a storage unit 142, and an interface unit 143, which are connected to each other via a bus (not shown). The processing unit 141 executes the program stored in the storage unit 142. The processing unit 141 is a CPU, for example.

  The storage unit 142 is, for example, a RAM, a ROM, a hard disk, or the like. The interface unit 143 is provided between the processing unit 141 and external devices (host computer 146, sensor 144, actuator 145), and is, for example, a communication interface or an I / O interface. The sensor 144 includes a sensor for detecting a fire, a sensor for detecting whether the start push button has been pressed, and the like, which will be described later. The actuator 145 includes a drive source for the pump 132 or a drive source for opening and closing the valve 133.

  Next, with reference to FIG. 2, a state where the water discharger 110 is deployed from the storage unit 120 of the vertical M will be described in detail. With reference to FIG.2 and FIG.3, the operation | movement until the water discharger 110 is expand | deployed is demonstrated. When the water discharger 110 is operated, the control device 140 starts the operation of the water discharge facility 1 by a signal from a sensor for detecting a fire (not shown) or a signal generated by pressing a start push button manually pressed by a person who has found the fire. .

  When a signal from the sensor 144 is input to the control device 140, the pump 132 connected to an external water source is activated, the valve is released, and water is supplied to the supply pipe 131. Water containing a predetermined pressure is supplied from the supply pipe 131 to the nozzle part 112 via the supply bellows part 114 and the tubular part 111 and discharged from the nozzle part 112. At this time, the water discharger 110 swings in the direction indicated by the arrow in FIG. 2 around the rotating part 113 due to the reaction caused by the water discharge from the nozzle part 112. Thus, the water discharger 110 is deployed from the storage part 120, and the nozzle part 112 moves away from the wall surface of the vertical M. In the present embodiment, the water discharger 110 is deployed by the water discharge from the nozzle unit 112, so the nozzle unit 112 serves as a water pressure utilization means.

  That is, the water discharger 110 further includes water pressure utilization means that swings the tubular part 111 from the first position to the second position by the water pressure of the water supplied to the tubular part 111. The water pressure utilization means is the nozzle portion 112.

  The water discharger 110 completes swinging and stops when the nozzle part 112 is separated from the wall surface by a predetermined distance so that water discharge from the nozzle part 112 appropriately forms a water curtain on the wall surface. As shown in FIG. 2, as a mechanism for stopping the swinging of the water discharger 110, a locking projection 117 provided at the end of the tubular portion 111 on the rotating portion 113 side and a wall surface of the storage portion 120 are provided. A locked protrusion 118 can be employed. The locking protrusion 117 moves with the swing of the tubular portion 111 by the water pressure utilization means and is locked to the locked protrusion 118, whereby the swing of the water discharger 110 is stopped. In addition to such a configuration, for example, the water discharger 110 is swung by a predetermined angle by a ratchet mechanism attached to the rotation shaft of the rotation unit 113, a one-way clutch mechanism, or the like, and then moved to the storage unit 120 side. You may comprise so that it may not return. That is, the water discharger 110 further includes a stopping unit that stops the swing when the swing to the second position is completed.

  Since the water discharger 110 is fixed in a deployed state, the water discharger 110 itself does not wobble due to the influence of the wind, and water can be discharged from a stable nozzle position to form an appropriate water curtain. Can do. In this way, as shown in FIG. 1, the water discharger 110 is in a deployed state, and it is possible to discharge water to the outer wall of the building BL with less influence of wind.

  The state of water discharge will be specifically described with reference to FIG. As shown in FIG. 1A, in a state where the water discharger 110 is deployed at an angle α with the vertical surface of the vertical M, the nozzle portion 112 faces the outer wall including the vertical M and the window glass WG. To discharge water. At this time, the nozzle part 112 is arrange | positioned so that the water discharge direction may face the outer wall side. By directing the water discharge direction, the water WC positively forms a water curtain on the outer wall side. Further, by discharging water toward the outer wall, the water WC has a momentum toward the outer wall surface, and even if the wind shown in FIG. Is less affected by wind flow.

  Moreover, as shown to FIG. 1 (B), the water discharger 110 is arrange | positioned at each of the vertical column M of several rows. When a plurality of water dischargers 110 are deployed, water curtains by water discharge from the respective water dischargers 110 can be formed so as to cover the entire outer wall by overlapping the water curtains adjacent to each other. In addition, in this embodiment, although the water discharger 110 is arrange | positioned to each of the plurality of columns M, it is not limited to this, If the water discharger 110 can discharge water to a wide range, the number will reduce. You may arrange.

  In the state before water discharge, the tubular portion 111 is disposed at the first position along the outer wall, so that the water discharger 110 does not stand up and protrude from the outer wall. Therefore, the installation of the water discharger 110 is less likely to appear on the exterior of the building BL, and the water discharger 110 is less likely to affect the design of the entire building BL. Further, by storing the water discharger 110 in the storage unit 120, the outer surface of the water discharger 110 and the outer surface of the vertical M form the same plane. By doing so, the installation of the water discharger 110 is less likely to appear on the exterior of the building BL, and the water discharger 110 is further less likely to affect the design of the entire building BL.

  In addition, since the mechanism for deploying the water discharger 110 is achieved mainly by the nozzle portion 112 and the rotating portion 113 of the tubular portion 111, the configuration is simplified and the structure can be easily incorporated in the vertical M or the like. . The vertical body incorporating the water discharger 110 can be replaced or replaced with a new one even after the building is built.

<Variation 1 of the first embodiment>
An example in which a bellows portion 115 is further provided adjacent to the supply bellows portion 114 of the water discharger 110 shown in FIGS. 1 and 2 will be described with reference to FIG. 4. 4, members having the same reference numerals as those in FIGS. 1 and 2 are members similar to the members described in FIGS. FIG. 4A is an enlarged view of the rotating portion 113 and the nozzle portion 112 of the water discharger 110, and shows a state where the water is stored in the storage portion 120 before the start of water discharge. FIG. 4B shows a state in which water is supplied to the water discharger 110 and the water discharger 110 is deployed as indicated by arrows in the drawing.

  As shown in FIG. 4 (A), in the present embodiment, a bellows portion 115 is provided adjacent to the supply bellows portion 114 to promote swinging of the water discharger 110 when the water discharger 110 is deployed. ing. One end of the bellows portion 115 is connected to a passage 116 to which water of the tubular portion 111 is supplied, and the other end is a bottomed cylindrical shape provided with a bottom portion, and is provided with a telescopic bellows. In the state shown in FIG. 4A, the bellows portion 115 is contracted, and the bottom portion of the bellows portion 115 is in contact with the bottom surface of the storage portion 120.

  Next, referring to FIG. 4B, the water supplied to the tubular portion 111 via the supply bellows portion 114 moves to the nozzle portion 112 at the distal end of the tubular portion 111. Is flowed to the bellows portion 115 adjacent to the supply bellows portion 114. The bellows portion 115 gradually expands when water is supplied, and biases the water discharger 110 to swing. In the present embodiment, the bellows portion 115 is also included as the water pressure utilization means.

  That is, the water pressure utilization means is disposed on the tubular portion 111 between the nozzle portion 112 and the support position (the rotation portion 113), and is disposed between the tubular portion 111 and the outer wall, and communicates with the tubular portion 111. A bellows portion 115 at the bottom is further provided, and the water supplied to the tubular portion 111 is accumulated in the bellows portion 115 so that the bellows portion 115 is extended and the water discharger 110 is urged to swing.

  At this time, the pressure of the water ejected from the nozzle part 112 is lower than that when the bellows part 115 is not provided because a part of the water is supplied to the bellows part 115. Furthermore, in the water discharger 110 of this embodiment, the water discharger 110 is slightly swung by the extension of the bellows part 115, and after the extension of the bellows part 115 is finished, the momentum of the water from the nozzle part 112 increases. The water discharger 110 is further swung and deployed. Therefore, it is possible to prevent the water discharger 110 from starting to swing rapidly at the start of operation. In addition, since the bellows portion 115 serves as a damper after the end of water discharge, the water discharge device 110 can be prevented from being stored suddenly due to a decrease in water pressure.

<Modification 2 of the first embodiment>
FIG. 5 shows an embodiment in which a nozzle part 112 is added to the water discharger 110 shown in FIGS. In FIG. 5, members having the same reference numerals as those in FIGS. 1 and 2 are members similar to the members described in FIGS. 1 and 2. In the water discharger 110 shown in FIG. 5, a nozzle part 112 is added adjacent to the rotating part 113. By doing so, as shown in detail in FIG. 5 (B) in particular, the outer wall of the upper part of the vertical M, the water can be discharged also near the connection point with the water discharger 110, A water curtain can be formed.

  In the embodiment shown in FIGS. 1 to 5 described above, the deployment of the water discharger 110 has been illustrated using water pressure, but is not limited to this, for example, a motor or a spring incorporated in the rotating unit 113. It may be deployed by a drive mechanism. Alternatively, a telescopic mechanism may be employed in which the tubular portion 111 formed in a nested shape is employed as the tubular portion 111 and a portion where the nozzle portion 112 is provided is extended by water pressure. Moreover, the location where the water discharger 110 is attached and the location where the storage unit 120 is provided are not limited to the vertical M, and a joint portion between the outer walls may be adopted. Furthermore, in this embodiment, although the water discharger 110 expand | deployed to a perpendicular direction was illustrated, you may store in the intangible T etc., for example, and may apply to the water discharger 110 expand | deployed horizontally.

<Second embodiment>
FIG. 6 shows a water discharge facility 2 according to the second embodiment of the present invention. As shown in FIG. 1 (B), for example, the water discharge facility 2 has an invisible T above the window glass WG on the outer wall including the vertical M and the invisible T, and the window glass WG surrounded by them. A water discharger 202 is provided. 6 (A) and 6 (B) are plan views of the water discharger 202 as viewed from above, for example, as shown in FIG. 8 (B).

  The water discharge facility 2 is erected on the vertical wall M on the side of the window glass WG, and has a plurality of plate-like louvers 201 extending along the vertical wall M, and a water discharger 202 disposed between adjacent louvers 201. , And a rotation mechanism 203. The water discharger 202 is provided on the seamless T on the upper end side of the window glass WG. The rotation mechanism 203 is a rotation unit that enables the louver 201 to rotate. The size of the louver 201 is not limited to the illustrated size, and the water discharged from the water discharger 202 is less likely to be affected by the wind and is set to a size that can reach a predetermined position. Good.

  FIG. 6A shows a state where water is discharged from the water discharger 202 in a state where the louver 201 is not rotated. Since the water discharger 202 is installed between the plurality of louvers 201 and the wind tends to be blocked by the louver 201, the water discharged from the water discharger 202 is less affected by the wind.

  FIG. 6B shows a state where the louver 201 is rotated by the rotation mechanism 203. The rotation mechanism 203 rotates the louver 201 so that the end portion separated from the outer wall of the louver 201 moves to the outer wall side. By appropriately rotating the louver 201 depending on the direction in which the wind blows, the diffusion direction of the water discharged from the water discharger 202 can be changed, so that the water is less affected by the wind. Therefore, it is possible to prevent the spread of fire by forming a water curtain on the window glass WG against a fire that has occurred outside.

  In addition, in the state shown in FIG. 6B, the louver 201 covers a part of the surface of the window glass WG when viewed from the outside of the building. It can be effectively protected. Specifically, as shown by a width W1 in FIG. 6A, in the state where the louver 201 is erected with respect to the outer wall, the entire surface of the window glass WG is exposed to the outside. On the other hand, as shown by the width W2 in FIG. 6B, since the louver 201 covers a part of the window glass WG, the portion (width W2) of the window glass WG exposed to the outside can be reduced. it can. This can prevent the radiant heat of the fire that occurred outside from reaching the window glass WG. That is, rotating the louver 201 not only reduces the influence of wind on the water discharged from the water discharger 202, but also serves to protect the window glass WG from the radiant heat of the fire. . Therefore, the spread of fire can be prevented more efficiently.

  In the second embodiment, all of the plurality of louvers 201 are rotated in the same direction. However, the present invention is not limited to this, and at least one of the plurality of louvers 201 may be rotated. Also, the direction in which the louvers 201 rotate does not have to be the same for all louvers 201. For example, you may rotate each of the louver 201 located in the both sides of the water discharger 202 to a mutually different direction. Moreover, although the material of the louver 201 is not specifically limited, you may employ | adopt wood. Since this embodiment allows water to be sprayed onto the wooden louver 201, it can be effectively used as an outer wall material of a building BL without using expensive processed wood with fire prevention measures, even if it is wood such as thinned wood. can do. Further, as the rotation mechanism 203, a drive mechanism such as a motor or a spring may be employed. Also in this embodiment, control by the control device used in the first embodiment can be performed. At this time, the actuator 145 includes a drive source that drives the rotation mechanism 203.

<Third embodiment>
FIG. 7 shows a water discharge facility 3 according to a third embodiment of the present invention. With reference to ST1 of FIG. 7, the structure of the water discharge facility 3 is demonstrated. The water discharge facility 3 is attached to a window frame 301 of a building, and is provided with a fire blind 302, a water discharger 303, an external water discharger 304, a fire detection device, which are disposed inside the building with respect to the window glass WG as a window member. 305 and a damage detection device 306. The water discharger 303 is disposed between the window glass WG and the fire blind 302 and can discharge water on the outer surface of the fire blind 302. The external water discharger 304 is attached to the outer wall of the building adjacent to the window frame 301. The fire detection device 305 is fire detection means for detecting a fire inside and outside the building. Examples of the fire detection device 305 include smoke detection type, photoelectric type, ionization type, heat detection type, ultraviolet detection type, carbon monoxide detection type, infrared detection type and the like. The installation location of the fire detection device 305 is not limited as long as it can detect a fire inside and outside the building, such as an outer wall and an inner wall of the building. The breakage detection device 306 is breakage detection means for detecting breakage of the window glass WG. In the present embodiment, the breakage detection device 306 is attached to the window glass WG, but the installation location is not limited to this. As the breakage detection device 306, for example, a glass breakage detector that detects vibration can be used.

  Next, how the water discharge facility 3 shown in FIG. 7 operates by detecting a fire will be described with reference to three state diagrams indicated by ST1, ST2, and ST3 in FIG. ST1 in FIG. 7 is a state where the water discharge facility 3 does not detect a fire. At this time, the fire blind 302 arranged inside the window glass WG is in the release position, and is in a state where the outside scenery can be seen and light from outside can be taken in.

  Next, ST2 of FIG. 7 shows a state in which, for example, a fire outside the building is detected by the fire detection device 305. The water discharge facility 3 that has detected the fire first activates the external water discharger 304 to protect the window glass WG from heat from an external fire. Next, the fire blind 302 is closed to prevent the radiant heat of the fire from entering the room. At this time, in the figure, the fire blind 302 is closed so as to close the entire window frame 301, but the present invention is not limited to this, and a part of the window frame 301 may be closed.

  Next, ST3 in FIG. 7 shows a state in which an external fire does not stop and the window glass WG is broken by the heat of the fire. The broken window glass WG is indicated by a dotted line in the figure. At this time, when the breakage of the window glass WG is detected by the breakage detection device 306 that detects breakage of the windowglass WG, the water discharger 303 disposed between the windowglass WG and the fire blind 302 is activated, The water discharger 303 starts water discharge. The water discharged from the water discharger 303 is mainly sprayed on the outer surface of the fire prevention blind 302, thereby protecting the fire prevention blind 302 from heat due to fire. Since the water WC on the surface of the fire blind 302 formed at this time is located inside the building by the window frame 301, it is less likely to be affected by external wind.

  In the state of ST3, as shown by the dotted line in the figure, the water discharge from the external water discharger 304 may be continued. Also in the present embodiment, control by the control device 140 used in the first embodiment may be performed. At this time, signals from the fire detection device 305 and the breakage detection device 306 can be adopted as the sensor 144, and the actuator that drives the water discharger 303 and the external water discharger 304 and the fire blind 302 are closed as the actuator 145. And an actuator to be driven can be employed.

  In the present embodiment, the window glass WG is adopted as the window member, but is not limited to glass, and may be a resin such as plastic or acrylic. Further, the window member is not limited to a transparent member that can see the outside. In addition to the blind of this embodiment, a roll curtain-shaped fire blind may be adopted as the fire blind 302.

  Moreover, the water discharge equipment and water discharger according to the first to third embodiments may be applied to a watering device for cooling a building. For example, by spraying water on the outer wall of a building at high temperatures such as in summer, the ambient temperature can be lowered by using latent heat of evaporation, and the air conditioning load inside the building can be reduced. Therefore, the water discharge facilities and water dischargers according to the first to third embodiments can also contribute to heat island mitigation in urban areas.
