Description

  The present invention relates to a sprinkling fire extinguishing equipment for a house, and relates to a sprinkling fire extinguishing equipment for a house suitable for a detached house, for example.

  In recent years, it has been desired to install fire extinguishing equipment in ordinary households. However, in general households, it is not easy to always store fire-fighting water. Has been.

  Many types of fire extinguishing equipment for home use have a structure that branches off the fire-fighting pipe from the home water-pipe. However, tap water is frequently used as domestic water for various purposes in the home. When there is a need to use as fire-fighting water, there is a problem that the amount of water is insufficient and a sufficient fire-extinguishing effect cannot be expected. In addition, there is a problem that water staying in a fire extinguishing pipe that is not normally used (so-called dead water) is mixed in the household pipe and contaminates domestic water.

  In order to solve these problems, the fire extinguishing equipment described in Patent Document 1 is configured such that a three-way solenoid valve is attached to the water main and is selectively switched between the fire extinguishing pipe side and the general water supply pipe side. . This fire extinguishing pipe is connected to a sprinkler installed in a place that needs to be extinguished in advance, and is normally supplied from the water main by keeping the water main and the general water supply pipe connected. Use the water as household water for domestic use. When the fire is extinguished, the three-way solenoid valve is automatically switched according to the signal from the heat sensor to shut off the general water supply pipe side and communicate with the water main and fire extinguishing pipe. In this way, the entire amount of clean water supplied from the water main can be sent to the sprinklers installed at each of the above locations and used for fire extinguishing water.

  The fire extinguishing equipment described in Patent Document 2 temporarily stores the water supplied from the water supply in a water storage tank, and at the time of fire extinguishing, the water is sucked up by a pump, and the sprinkler provided in the house in advance. It is configured to be supplied as fire-fighting water. Accordingly, a predetermined amount of water can be secured by operating the pump, and the water supply and the water storage tank are separated, so that it is not possible for the accumulated water to be mixed into the household piping.

Japanese Utility Model Publication No. 5-9563 JP-A-10-127812

  By the way, the fire extinguishing equipment of Patent Documents 1 and 2 can discharge water only at a place where a sprinkler is installed in advance, and cannot flexibly cope with the case where it is desired to concentrate water on an arbitrary ignition source. In addition, since it is necessary to perform large-scale piping work inside the building, when it is applied to an existing house, the burden increases in terms of cost and construction period, and there may be cases where it cannot be applied depending on the house.

  Moreover, since the fire extinguishing equipment described in Patent Document 2 sucks up the stored water with a pump and supplies it to the sprinkler, the initial cost associated with the installation of the pump and the running cost for operation and maintenance management are large.

  In addition, the fire extinguishing equipment described in the above-mentioned documents 1 and 2 is intended only for fire extinguishing, and when applied to a general household such as a detached house, it has a high added value such that it can be used for other purposes. It is desirable.

  The present invention has been made in view of such problems, and provides a sprinkling fire extinguishing facility for a house that can be easily installed in an existing detached house and can be used for purposes other than fire extinguishing. It is intended to do.

In order to solve the above problems, the present invention
First, a three-way switching valve having one inlet and two switchable outlets communicating with the inlet is provided, and a water supply main branched from a public water pipe is provided at the inlet of the three-way switching valve. Connected to the outlet of one of the three-way selector valve is connected to an in-house pipe for supplying tap water flowing from the water supply main pipe into the house as domestic water, and to the other outlet of the three-way selector valve. A watering fire extinguishing equipment for a house, which is formed by connecting a hose with a nozzle attached to the tip, and is formed by connecting the inlet and the one outlet through the switching means of the three-way switching valve. And either one of the water sprinkling / extinguishing water conduits formed by communicating the inlet and the other outlet can be selectively switched, and the hose and the three-way switching valve are connected to a fire hydrant box with an open / close door. For housing, characterized by being housed It is formed using water extinguishing systems.

  When configured in this way, the nozzle can be moved to an arbitrary location within the entire length of the hose, so that water can be discharged by concentrating on a specific ignition source, and other than fire extinguishing such as watering a garden or washing a car. It can also be used for other applications. In addition, in the state where the water pipe for watering and extinguishing is formed, the entire amount of tap water is supplied to the watering fire hose, so that it is possible to secure the amount of water necessary for fire extinguishing. Moreover, since the action which takes out the said hose and switches the said three-way switching valve and selects the water pipe for sprinkling fire extinguishing can be performed in the fire hydrant box, the fire extinguishing preparation work can be carried out simply and smoothly.

  Secondly, the switching means is configured by a manual switching lever, and the three-way switching valve is switched by rotating the lever, and the life is operated by the three-way switching valve by rotating the switching lever. In the state where the irrigation pipe is formed, the switching lever is housed in the fire hydrant box so that the opening / closing door can be closed, and the three-way switching valve is operated by rotating the switching lever. In the state in which the water pipe for watering and extinguishing is formed, the switching lever is configured to be positioned at a closing obstruction position for preventing the opening and closing of the door. Consists of sprinkling fire extinguishing equipment.

  Therefore, in the fire extinguishing or watering state in which the water pipe for watering and extinguishing is formed, it is impossible to close the open / close door by the switching lever, so that forgetting to switch the three-way switching valve can be prevented. The closing obstruction position of the switching lever is, for example, in a state where the water sprinkle-extinguishing water conduit is formed, the lever is in a horizontal rotating state, and the tip of the lever contacts the inner surface of the opening / closing door to prevent the opening / closing door from closing. Says the position.

  Third, the open / close door is made transparent or translucent, and is constituted by the water sprinkling and extinguishing equipment for a house according to the first or second aspect.

  When configured in this way, the hose and the three-way switching valve inside the box can be visually confirmed through a transparent or translucent opening / closing door, so that the facility can be easily confirmed as a fire extinguishing facility, and the installation location of the fire hydrant box Depending on the situation, it is possible to realize a fire extinguishing facility that can be used not only by residents but also by outsiders, for example.

  Fourth, the fire hydrant box is fixed on a stand erected on the ground, and the water supply main pipe and home piping are piped in the stand. It is comprised of the sprinkling fire extinguishing equipment for houses described in the above.

  With this configuration, for example, by installing the fire hydrant box in a self-supporting state in the vicinity of the entrance outside the house, it is possible to report the occurrence of a fire to not only the resident but also, for example, an outside person. A possible fire extinguishing facility can be realized.

  Fifth, the fire hydrant box is attached to a wall surface in a house, and is constituted by the water sprinkling and extinguishing equipment for a house according to any one of the first to third aspects.

  According to the present invention, it is not necessary to install a sprinkler or the like in the building in advance, it is easy to retrofit not only in a newly built house but also in an existing house, and there is no need for water measures for so-called death. It is possible to realize low-priced water sprinkling fire extinguishing equipment with simple construction.

  In addition, the length of the hose can be freely selected according to the scale of the house, and it has flexibility with respect to the fire-extinguishing position. Can do.

  In addition, since the three-way selector valve can be switched arbitrarily, it is not limited to fire extinguishing, but can be used for other purposes such as garden watering and car washing, and has high added value fire extinguishing equipment for residential use. Can be realized.

  An embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a system configuration diagram showing an embodiment of a residential sprinkling fire extinguishing facility according to the present invention.

  In the figure, reference numeral 2 denotes a water supply main drawn into the site of the house 10, and the upstream side is connected to the public water pipe 1 via a water meter 2 a, and water is supplied from the public water pipe 1.

This in-house piping 3 is continuously piped downstream of the upright pipe 3a at various locations in the house 10, and from the public water pipe 1 to the inlet 5a and first outlet 5b of the three-way switching valve 5. The tap water is supplied to the water facility in the house 10 via the. Specifically, the in-house piping 3 supplies tap water to the taps P of the kitchen 10a, the washroom 10b, and the bathroom 10d, and further supplies tap water to the water supply tank of the toilet 10c.

  4 is a sprinkling fire hose (hose) connected to the second outlet 5c of the three-way switching valve 5, and the hose body is wound and stored in a pair of hose hangers 6f, 6f provided in the fire hydrant box 6. Has been. The water spray fire hose 4 has a water spray fire extinguishing nozzle (nozzle) 4a provided with an open / close valve capable of switching fire water into a sprayed state or a stopped state, and closes the valve of the water spray fire extinguishing nozzle 4a. Thus, it is configured to stop the discharge of fire-extinguishing water. It should be noted that, if the sprinkling fire extinguishing nozzle 4a is provided with a throttle mechanism so that the sprinkling amount and sprinkling range can be adjusted, the sprinkling fire extinguishing can be performed more effectively.

  Reference numeral 5 denotes a three-way switching valve installed in the fire hydrant box 6, and as described above, the end of the upright pipe 2b of the water supply main pipe 2 is connected to the inlet 5a, and the first outlet 5b Is connected to the end of the upright pipe 3a of the in-house piping 3, and to the second outlet 5c is connected to the base end (detachable part) of the watering fire hose 4.

  In the three-way switching valve 5 (see FIG. 4), 5e is a ball valve provided at a branch portion of the inlet 5a and the outlets 5b and 5c. The ball valve 5e rotates the valve 5e by 90 degrees. A drive shaft 5f for driving is connected (see FIG. 5). One end of the drive shaft 5f protrudes outside the housing of the switching valve 5, and the base end of the manual switching lever 5d for rotating the ball valve 5e by 90 degrees and switching the flow channel is fixedly connected to the one end. Has been.

  When the manual switching lever 5d is raised in the vertical direction as shown in FIG. 4 (a), the ball valve 5e completely closes the second outlet 5c to the sprinkling fire hose 4 and An inlet 5a and a first outlet 5b are connected to each other to connect the water supply main pipe 2 and the home piping 3 to form a “commercial water pipe” that supplies the entire amount of the tap water to the home piping 3 ( This position of the switching lever 5d is referred to as “normal water supply position”), and when the switching lever 5d is rotated 90 degrees from the vertical standing state and rotated to a horizontal state as shown in FIG. The ball valve 5e is also rotated 90 degrees, and the ball valve 5e completely closes the first outlet 5b, and flows into the water supply main pipe 2 by connecting the inlet 5a and the second outlet 5c. Sprinkle fire hose 4 for the total amount of tap water And supplies "sprinkler water line" is configured so as to form a (referred to as "sprinkler position" the position of the switching lever 5d).

  As described above, the ball valve 5e selectively communicates either the inflow port 5a and the outflow port 5b or 5c. When the ball valve 5e is in communication with one outflow port 5b or 5c, the other outflow port is provided. The outlet 5c or 5d is configured to be blocked. Therefore, tap water flows only in the channel Q (FIG. 4A) when the water pipe for domestic use is formed, and the second outlet 5c side is completely blocked. In addition, since the tap water flows only in the flow path R (FIG. 4 (b)) and the first outlet 5b side is completely shut off when the water sprinkling / extinguishing water pipe is formed, it is used as domestic water in the house 10 Even during the operation, the supply of tap water is stopped, and it becomes possible to use the entire amount of tap water supplied from the water supply main pipe 2 as water for sprinkling fire extinguishing.

  Further, in the normal water supply position (FIG. 4 (a)) of the three-way switching valve 5, tap water is not supplied to the water spray fire hose 4 at all, so that no so-called dead water is generated. There is no risk of death and water, and there is no need to take separate measures against water.

  Next, the fire hydrant box 6 will be described in detail with reference to FIGS. In the fire hydrant box 6, 6 ′ is a cylindrical main body including a circular bottom plate 6 a and a cylindrical outer peripheral wall 6 b, and a hinge 6 c attached to the outer peripheral wall 6 b is provided on the front side of the main body 6 ′. A circular opening / closing door 6d that is rotatable and opens and closes the front surface of the main body is provided. The circular opening / closing door 6d is formed of a transparent or translucent acrylic resin or the like, and is configured so that the water sprinkling fire hose 4 and the three-way switching valve 5 can be seen even when the opening / closing door 6d is closed. Yes. Further, characters 6e such as “water sprinkler hydrant” are written in red on the surface of the opening / closing door 6d so that any person can be warned that the main body 6 'is a fire hydrant.

  On the bottom plate 6a inside the fire hydrant box 6, the hose hangers 6f and 6f are fixed in two vertical directions with a predetermined distance, and the watering fire hose 4 is wound around the hose hanger 6f. It is stored. In consideration of the diameter and extension of the hose 4, the hose hangers 6f are appropriately selected in installation position and separation distance so that the hose 4 can be stored in the fire hydrant box 6 in a state where the entire length of the hose 4 is wound. The For example, a rotary drum can be installed in the fire hydrant box 6 and the hose 4 can be wound around and stored in the outer periphery of the drum. In this way, the hose 4 can be easily taken out and rolled up. , Can contribute to quick fire fighting.

  In the fire hydrant box 6, the three-way switching valve 5 is fixedly provided adjacent to the watering fire hose 4. The switching lever 5d of the three-way switching valve 5 is housed in the fire hydrant box 6 in the normal position standing in the vertical direction, as shown in FIG. 6d can be closed without hindrance. On the other hand, in the sprinkling fire extinguishing position that is tilted horizontally, the tip of the switching lever 5d protrudes from the front surface of the fire hydrant box 6 as shown in FIG. 2 (b), and the tip is closed by the opening / closing door 6d. The door 6d is previously brought into contact with the inner surface of the door 6d to prevent the opening / closing door 6d from closing (this position of the switching lever 5d is referred to as a “closing obstruction position”).

  Accordingly, when the lever 5d is in the horizontal sprinkling fire extinguishing position, that is, when the water sprinkling water conduit is formed, the opening / closing door 6d cannot be completely closed. Therefore, when the opening / closing door 6d is closed, the switching lever 5d must be closed. By forcing it to stand up and turn, it is possible to prevent forgetting to switch to a domestic water pipeline after sprinkling fire.

  Reference numeral 7 denotes a stand for fixing the fire hydrant box 6 at the tip thereof. For example, a concrete base 7a is formed near the entrance outside the house 10, and is fixed on the base 7a in an upright state. As shown in FIG. 2, the water supply main pipe 2 is piped as an upright pipe 2 b from the underground via the foundation 7 a and connected to the inlet 5 a of the three-way switching valve 5 in the fire hydrant box 6. Has been. Similarly, the standing pipe 3a of the indoor piping 3 is piped from the underground as the standing pipe 3a through the foundation 7a and connected to the first inlet 5b of the three-way switching valve 5. . If the stand 7 is damaged, the piping is adversely affected. Therefore, the stand 7 is made of a strong material such as iron and the surface thereof is subjected to rust prevention treatment. The fire hydrant box 6 and the stand 7 are fixed by welding. These materials and fixing methods are not limited to those described above, and any material that can prevent damage to the piping may be used.

  When the ground where the fire hydrant box 6 is installed is a civil engineering structure such as asphalt or concrete, the stand 7 can be directly fixed to the ground with an anchor bolt or the like. When installing, in order to prevent collapse, it is necessary to provide the above-mentioned foundation 7a stabilized by concrete or the like and fix it on the foundation. Further, in order to facilitate fire extinguishing work, it is desirable to install the fire hydrant box 6 at a certain height, which can be dealt with by adjusting the height (length) of the stand 7.

  In addition to supporting the fire hydrant box 6 with the stand 7 as described above, the fire hydrant box 6 is attached by embedding only the fire hydrant box 6 in a wall surface inside or outside the house without providing the stand 7 as shown in FIG. Can also be used. Even when the stand 7 is used, the stand 7 can be installed not only outdoors but also at appropriate places indoors.

  Reference numeral 8 denotes a red light provided in the fire hydrant box 6 so as to be visible through the transparent door 6d. By attaching the red light 8, the position of the fire hydrant box 6 can be easily understood even in the dark, and quick fire extinguishing activities can be performed. A fire alarm speaker 9 is also provided in the fire hydrant box 6 and emits an alarm sound based on a fire detection by a fire detector 10e described later.

  Next, an electrical configuration relating to fire detection, alarms, notifications and the like according to the present invention will be described. The electrical configuration such as notification described below is not necessarily required for the fire hydrant facility of the present invention, and the object of the present invention can be achieved without the following electrical configuration.

  In FIG. 1, 10e and 10e are fire detectors fixed to the ceiling of an appropriate place (for example, each room) of the house 10, and when detecting smoke and heat accompanying the occurrence of a fire, the detection signal is fired. This is sent to the automatic notification device 10f. 10f is an automatic fire alarm device having the output section connected to the fire alarm speaker 9, which sends an alarm signal to the speaker 9 based on reception of the detection signal, thereby driving the speaker 9 The occurrence of a fire is notified by an alarm sound or voice. At this time, the automatic fire reporting device 10f and the red light 8 are connected, the red light 8 is blinked by the reporting device 10f, or a patrol light is provided as the red light 8 to drive the patrol light. By doing so, it is possible to notify the occurrence of a fire more effectively, and for example, it is possible to notify the occurrence of a fire early to outside persons such as passers-by. In addition, the automatic fire reporting device is connected to a general telephone line, and is configured to automatically report to a predetermined place (for example, a fire department) based on reception of the detection signal or to automatically notify a predetermined mobile phone. be able to.

  The operation of the residential sprinkling fire extinguishing system configured as described above will be described below. In a state in which no fire has occurred, the switching lever 5d of the three-way switching valve 5 in the fire hydrant box 6 is in a normal water supply position (state for forming a domestic water pipe) in the vertical direction. Accordingly, the tap water supplied from the public water pipe 1 passes through the water supply main pipe 2, the inlet 5a of the three-way switching valve 5, and the first outlet 5b installed in the house 10 through the water meter 2a. It flows into the in-home piping 3 and is in a state where it has been filled up to the end of the faucet P and the toilet 10c in various places in the house 10. At this time, since the second outlet 5c of the three-way switching valve 5 is closed, the watering fire hose 6 is in a state where no water is present inside. Therefore, in this state, the tap water can be used as domestic water in the water facilities in the house 10, for example, the kitchen 10a and the washroom 10b, the toilet 10c, and the bathroom 10d.

  Here, when a fire occurs in any place inside or outside the house 10, the fire extinguisher opens the open / close door 6d of the fire hydrant box 6 and tilts the switching lever 5d of the three-way switching valve 5 horizontally in the forward direction. The sprinkling fire extinguishing position is set, and the sprinkling fire extinguishing hose 4 has the sprinkling fire extinguishing nozzle 4a. While unfastening the hose 4, the fire is expedited to the fire site and the sprinkling fire extinguishing nozzle 4a is pointed at the fire occurrence point and the open / close valve of the nozzle 4a is opened . When the fire detector 10e is installed, it is possible to know the occurrence of a fire from the alarm sound of the fire alarm speaker 9 by the automatic fire alarm device 10f. Further, for example, a notification is made from the automatic fire notification device 10f to a fire department, a specific mobile phone or the like through a telephone line.

  Then, the first outflow port 5b of the three-way switching valve 5 is closed, and the inflow port 5a and the second outflow port 5c communicate with each other to form a water sprinkling / fire extinguishing water conduit. The total amount of the supplied tap water flows into the watering fire hose 4 and can be discharged from the watering fire extinguishing nozzle 4a toward the fire occurrence site at a predetermined water pressure. At this time, the residential piping 3 side is completely closed, and thus water for daily life cannot be used. However, since the entire amount of tap water from the water supply main 2 can be used for fire extinguishing work, The necessary amount of water can be secured and there is no risk of water shortage.

  After the fire is extinguished, the switching lever 5d is returned to the normal vertical state so that the pipe in the three-way switching valve 5 is switched to the domestic water pipe and used as domestic water (the domestic water pipe). Returning to the path forming state), the water in the water sprinkling fire hose 4 is drained and wrapped around the hose holder 6f, and the open / close door 6d is closed.

  Further, since the switching lever 5d is in a horizontal rotation state during the fire fighting operation, the opening / closing door 6d cannot be closed, thereby notifying the third party that the fire fighting operation is being performed. it can. In addition, when the fire extinguishing work is finished, the open / close door 6d cannot be closed if the switching lever 5d remains in the horizontal rotation state (closing obstruction position), so that the fire extinguisher always puts the switching lever 5d in the vertical state. The opening / closing door 6d is closed after returning. Therefore, forgetting to switch to the home piping 3 can be prevented.

  Further, since the switching of the pipe line by the switching lever 5d can be arbitrarily performed manually, the lever 5d can be arbitrarily switched to the sprinkling fire extinguishing pipe other than when a fire occurs. Therefore, it can be used for applications such as watering the garden, washing a car, and washing the outer wall of a house.

  As described above, according to the present invention, it is not necessary to previously install sprinkler equipment in the building as in the prior art, and it is easy to retrofit not only in newly built houses but also in existing houses. Because there is no need for water countermeasures, it is possible to realize a low-priced water sprinkling fire extinguisher with relatively simple construction.

  In addition, the length of the sprinkling fire hose 4 can be freely selected according to the scale of the house 10 and has flexibility with respect to the fire-extinguishing position. Activities can be realized.

  Moreover, since the water spray fire extinguishing equipment according to the present invention can arbitrarily switch the three-way switching valve 5, the water spray fire extinguishing equipment is not limited to fire extinguishing, but other uses such as garden water sprinkling, car washing, house exterior wall cleaning (for example, It can also be used for fire-fighting training, etc., and a fire-extinguishing facility with high added value can be realized for residential use.

  Moreover, since it is the structure which switches the water sprinkling fire hose 4 and the home piping 3 by the three-way selector valve 5, simultaneous use of fire-fighting-use water and domestic water can be avoided reliably, and the amount of water and water force required at the time of fire-fighting are ensured. be able to.

  In addition, since the residents can easily perform fire fighting training, it is possible to carry out fire fighting activities without being confused when a fire breaks out.

  In addition, by installing a fire hydrant box in an independent state outside the house, it is possible to provide a fire extinguishing facility that can notify not only residents but also outsiders, for example, to the occurrence of a fire, and external people can also perform fire fighting activities. .

  In addition, since the open / close door 6d of the fire hydrant box 6 is made transparent or translucent, not only residents but also outside persons (for example, passers-by) can use the sprinkling fire extinguishing equipment without hesitation. Very effective for initial fire fighting.
