  However, in facilities that prohibit tunnel entry using such traffic lights and information display panels, traffic lights are generally not regulated on expressways and motorway roads, so traffic lights turn red. However, even if you enter the tunnel without noticing it, you will not be able to grasp the situation even if you notice a red light, so it is assumed that you will enter as it is, which may lead to a serious accident. Also, if the tunnel is long, the traffic lights will not be useful for vehicles that have already entered.

  Also, traffic lights and information display panels are installed in tunnels with heavy traffic and long distances. However, for short tunnels of 2 km or less, for example, it is not possible to install traffic lights or information display panels on all of them. If an abnormality such as an accident or a vehicle fire occurs in such a tunnel, it will enter the tunnel without noticing the abnormality, and it will stop immediately after approaching the site where the accident occurred There is a risk of an accident.

  An object of the present invention is to provide a fire hydrant apparatus that can visually notify a traveling driver of the occurrence of an abnormality in a tunnel using a fire hydrant facility and can make an emergency stop before a tunnel entrance. And

The present invention is a fire hydrant device that is installed in a tunnel and draws a hose with a nozzle to discharge water,
An emergency head that discharges water into the tunnel to form an emergency pattern,
A valve device for supplying pressurized fire-fighting water to the emergency head,
A control device that controls the valve device to discharge water from the emergency head when the water spray water discharge detection switch that detects the water discharge of the water spray equipment installed in the tunnel before the start of water discharge;
Is provided.

  Here, the emergency head is arranged on one side or both sides in the tunnel.

  The emergency head is installed outside the housing and connected to the valve device in the housing by piping.

  The emergency head is installed in the housing and discharges water from a water discharge opening formed in the housing.

  When water is discharged from the emergency head, the control device discharges water from the emergency head of the fire hydrant device in one or more sections in front of the installation section.

  The emergency sense head forms a rod-like pattern as the emergency sense pattern.

  The emergency head forms a bar-like pattern obliquely with respect to the direction across the lane and / or the direction along the lane.

  The emergency sense head forms a rod-like pattern in a direction transverse to the lane.

  A plurality of emergency sensing heads are arranged to form a plurality of bar-shaped patterns.

  The emergency awareness head discharges water intermittently or periodically to form a bar-shaped pattern.

  According to the fire hydrant device of the present invention, when an abnormality such as an accident or a vehicle fire occurs in a tunnel and a water hose with a nozzle is pulled out from a fire hydrant device installed nearby, Based on the detection of emergency equipment operation such as detecting the opening of a fire hydrant valve, water is discharged in the lane direction in the tunnel from the emergency head connected to the fire hydrant device in the abnormal zone to form an emergency notification pattern. Even if the driver makes an emergency stop after seeing the emergency sense pattern, and breaks through without being aware of the emergency sense pattern, the driver knows that the vehicle has watered, stops the emergency, and enters the location where the abnormality occurred. It is possible to prevent the occurrence of secondary disasters.

  In addition, the water discharge pattern from the emergency head is made into a rod-shaped pattern, and by performing oblique water discharge, cross water discharge, side water discharge, etc., the driver can be notified of the occurrence of an abnormality due to the minimum water discharge amount equivalent to the water discharge amount of the fire hydrant device. You can be surely aware. Moreover, it can discharge without disturbing the smoke layer formed in the tunnel upper part by the water discharge by a rod-shaped pattern.

  A pump start switch 57 is arranged in front of the water supply valve 54. The water supply valve 54 and the pump start switch 57 are devices that the fire brigade operates when extinguishing the fire, and even if the fire hydrant door 30 is opened, it is hidden by the maintenance door 32 and is not shown to the general user who wants to operate the fire hydrant device. , So as not to cause unnecessary confusion.

  In the present embodiment, the signal from the valve opening / closing detection switch and the pump activation switch 57 installed behind the fire hydrant valve opening / closing lever 55 can also be used as a control signal for performing conscious water discharge from the emergency conscious head.

  FIG. 3 is an explanatory view showing an embodiment of a water discharge valve system provided in the fire hydrant apparatus of the present invention. In FIG. 3, a water supply valve 54, a fire hydrant valve 56, an automatic pressure regulating valve 58, an emergency notification water discharge valve 60, an automatic drain valve 62, and a pressure sensor 64 are provided in a valve storage space.

  The fire hydrant valve 56 is branched and connected to the primary pipe of the water supply valve 54 connected to the water supply pipe extending from the water supply source, and is opened and closed by operating the fire hydrant valve opening / closing lever 55. The automatic pressure regulating valve 58 is connected to the secondary side of the fire hydrant valve 56 and adjusts the water discharge pressure on the hose 50 side to a specified pressure.

  The emergency tactile water discharge valve 60 uses an electric valve, functions as a valve device for tactile water discharge, is provided in a pipe branched from the primary side of the fire hydrant valve 56, and has a head that draws the secondary side to the outside. The pipe 24 is connected, and the opening / closing control is performed by the control device 11 shown in FIG. The emergency sensing head 14 is connected to the tip of the head pipe 24. If necessary, a plurality of emergency sensing heads 14 can be provided as shown by the dotted emergency sensing head 14.

  Further, the emergency notification water discharge valve 60 is controlled by the control device 11 of FIG. 1 so as to keep the detection pressure of the pressure sensor 64 provided on the secondary side at a predetermined discharge water pressure, whereby the discharge pressure from the emergency notification head 14 is controlled. Can be adjusted to the specified pressure.

  The automatic drain valve 62 is opened when there is no pressure, and is closed when pressure is applied. The automatic drain valve 62 is opened when the emergency sensation water discharge valve 60 is closed after conscious discharge, and drains water from the head pipe 24.

  FIG. 4 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant device of the present invention, and is characterized in that an emergency head is built in the fire hydrant device.

  In FIG. 4, the water supply valve 54, the fire hydrant valve 56, the automatic pressure regulating valve 58, the emergency sense water discharge valve 60, the automatic drain valve 62 and the pressure sensor 64 provided in the valve storage space are the same as those in the embodiment of FIG. 3. For example, three emergency awareness heads 14 are accommodated in the housing of the fire hydrant device 10, a water discharge opening 25 indicated by a dotted line is formed on the front surface of the housing relative to the head opening, and a bar-shaped pattern of water discharge is provided outside. Like to do.

  The emergency head 14 is disposed, for example, behind the maintenance door 22 shown in FIG. 2A, and forms a water discharge opening 25 at the position of the maintenance door 22 opposite the head end. The water discharge pattern discharged from the emergency awareness head 14 is formed at an angle or orientation that does not interfere with the person who operates the fire hydrant device 10. The water discharge opening 25 has a lid structure and is opened only during water discharge. Moreover, it is good also as a structure which the emergency awareness head 14 extends outside from the fire hydrant apparatus 10 only at the time of water discharge.

  By incorporating the emergency awareness head 14 in the fire hydrant apparatus 10 in this way, installation and piping of the emergency awareness head on the exterior tunnel wall surface and the like are not required, and the installation work can be simplified and the cost can be reduced.

  Next, an emergency sense pattern by the emergency sense head of this embodiment will be described with reference to FIGS.

  5A and 5B are explanatory views showing lateral water discharge by a stick-like pattern of the emergency head, FIG. 5A shows a tunnel cross section, and FIG. 5B shows a tunnel plane.

  In FIG. 5, the emergency awareness head 14 discharges water with a bar-like pattern 15 in order to minimize the amount of water discharge necessary for awareness, and in this embodiment, the emergency cross section 14 has a tunnel cross section in FIG. As shown in the figure, water is discharged from the emergency head 14 on the side wall of the tunnel connected to the head pipe 24 from the fire hydrant device 10 in the direction of right across the road with a bar-like pattern 15 and shown in the tunnel plane of FIG. In addition, the rod-like pattern 15 is discharged in a direction transversely to the running direction.

  By such horizontal discharge of the bar-shaped pattern 15, a vehicle traveling in the tunnel 12 can recognize the occurrence of an abnormal situation by seeing the water discharge by the bar-shaped pattern 15 that crosses the road in the traveling direction, and does not notice the discharge. By receiving water discharge across the side of the vehicle body, it is possible to recognize the occurrence of an abnormal situation.

  In addition, a smoke layer is formed in the upper part of the tunnel due to the occurrence of a fire. However, since the rod-shaped pattern 15 from the emergency awareness head 14 is lateral water discharge at a position close to the road surface of the road 22, the smoke layer is disturbed by the water discharge. Smoke does not spread throughout.

  Furthermore, since the fire-fighting water discharged in a rod shape is discharged to the opposite wall surface of the tunnel, it is drained to a drain outlet provided below the wall surface, so it does not stay on the road, so secondary vehicles such as slipping It is also possible to prevent disasters as much as possible.

  The height of the bar-shaped pattern 15 is not particularly limited. However, when the height is set to be slightly higher than the height of a general vehicle, fire-fighting water is not applied to the passing vehicle, which hinders the driver's view. There is nothing.

  FIG. 6 is an explanatory view showing oblique water discharge by the rod-like pattern of the emergency head. In this embodiment, as shown in the tunnel cross section of FIG. 6 (A), the rod-shaped pattern 15 from the emergency head 14 on the side wall of the tunnel connected to the head pipe 24 from the fire hydrant device 10 crosses the road. As shown in the tunnel plane of FIG. 6 (B), the rod-shaped pattern 15 is discharged obliquely with respect to the traveling direction.

  Due to the oblique water discharge of the rod-shaped pattern 15, the vehicle traveling in the tunnel 12 crosses obliquely from the traveling direction, so that the occurrence of an abnormal situation is noticed by seeing the water discharge by the rod-shaped pattern 15, and the water discharge is not noticed. In both cases, it is possible to recognize the occurrence of an abnormal situation by receiving water discharge obliquely across the vehicle body.

  In addition, a smoke layer is formed in the upper part of the tunnel due to the occurrence of a fire. However, since the rod-shaped pattern 15 from the emergency head 14 is an oblique water discharge near the road surface of the road 22, the smoke layer is disturbed by the water discharge and the tunnel is disturbed. Smoke does not spread throughout.

  FIG. 7 is an explanatory view showing cross water discharge by a bar-shaped pattern in an embodiment in which an emergency head is arranged in a tunnel.

  7A, the emergency head 14 connected to the head pipe 24 from the fire hydrant apparatus 10 is arranged on the side wall of the tunnel 12 in the tunnel cross section, and further, the head pipe 24 is placed on the side of the tunnel opposite to the upper side of the tunnel. Piping, the emergency head 14 is disposed there, and the bar pattern 15 is discharged from the emergency head 14 installed on the side walls on both sides of the tunnel in the direction across the road. As shown in the tunnel plane, cross-water discharge is performed by discharging the rod-shaped pattern 15 obliquely in the traveling direction from the emergency heads 14 arranged on both sides.

  By such two cross water discharges of the bar-shaped pattern 15, the vehicle traveling in the tunnel notices the occurrence of an abnormal situation by seeing the water discharge by the bar-shaped pattern 15 that crosses and crosses in the traveling direction, and discharges water. Even if you do not notice, you can be aware of the occurrence of an abnormal situation by receiving water discharge diagonally across the car body.

  In addition, if cross water discharge is performed simultaneously from the emergency heads 14 provided in the plurality of fire hydrant devices 10 arranged at predetermined intervals in the tunnel traveling direction, a plurality of cross water discharge patterns emerge in front of the tunnel, and an abnormal situation occurs. You can be sure. Moreover, since the cross water discharge becomes a water discharge near the road surface, the smoke layer formed at the upper part of the tunnel is not disturbed.

  Further, it is possible to prevent the driver's view from being obstructed even in cross water discharge.

  FIG. 8 is an explanatory view showing multi-water discharge by a bar-shaped pattern in an embodiment in which a plurality of emergency detection heads are arranged, and an example in which three emergency detection heads are provided is taken as an example.

  8A, three emergency heads 14 connected to the head pipe 24 from the fire hydrant device 10 are arranged on the side wall of the tunnel 12, and the rod-shaped pattern 15 is discharged in a direction crossing the road 22. doing. Further, in the tunnel plane of FIG. 8B, the multi-water discharge is performed from the three emergency sensing heads 14 in the direction transverse to the side and in different oblique directions.

  By the multi-water discharge using such a bar-shaped pattern 15, a vehicle traveling in the tunnel can recognize the occurrence of an abnormal situation by watching the water discharge by the bar-shaped pattern 15. It is easier to notice by water discharge than a single water discharge pattern. If the pattern position is set so that the vehicle body receives the water discharge even if the water discharge is not noticed, the occurrence of an abnormal situation can be recognized by the sound and water droplets received by the vehicle body. Moreover, if the water is discharged near the road surface, the smoke layer formed at the upper part of the tunnel will not be disturbed. Even if a water discharge pattern is formed in the smoke layer, it is a rod-shaped pattern, so there is not enough power to disturb the smoke layer.

  FIG. 9 is an explanatory view showing another embodiment of multi-water discharge by a bar-shaped pattern in which a plurality of emergency detection heads are arranged, and an example in which three emergency detection heads are provided is taken as an example.

  In the present embodiment, the tunnel cross section of FIG. 9A is also multi-directional in the direction across the road 22 from the three emergency sensing heads 14 connected to the head pipe 24 from the fire hydrant device 10 in different diagonal directions. The water is discharged. Also, the tunnel plane of FIG. 9B also multi-sprays the bar-shaped pattern 15 from the three emergency sensing heads 14 in a direction transverse to the side and in different oblique directions.

  By such multi-water discharge using the bar-shaped pattern 15, a vehicle traveling in the tunnel recognizes the occurrence of an abnormal situation by watching the water discharged by the bar-shaped pattern 15 and receives the water discharge even if the water discharge is not noticed. Thus, the occurrence of an abnormal situation can be known.

  In addition, the water discharge by the rod-like pattern of the emergency head 14 shown in FIGS. 5 to 9 is the upward water discharge within a range that does not disturb the smoke layer above the tunnel other than the horizontal water discharge and the multi-water discharge from a plurality of emergency heads. Can be made into an appropriate water discharge pattern such as cross water discharge.

The emergency notification water discharge valve 60 uses an electric valve, and is provided in the branch pipe on the secondary side of the automatic pressure regulating valve 56, connected to the head pipe 24 drawn to the outside on the secondary side, and the control device of FIG. 11 is controlled to open and close.

  Since the emergency sense water discharge valve 60 supplies the fire extinguishing water adjusted to the specified pressure by the automatic pressure regulating valve 58 to the emergency sense head 14, it is necessary to provide a pressure sensor 64 and control the pressure as in the embodiment of FIG. No, it ’s easy. The pressure switch 68 is turned on in response to the pressure at the time of supplying pressurized fire-extinguishing water to the emergency awareness head 14, and for example, sends a detection signal to the disaster prevention receiver 18 of FIG.

  The automatic drain valve 62 drains the fire-extinguishing water in the head pipe 24 when the alert water discharge is stopped by closing the emergency water discharge valve 60.

  FIG. 11 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant apparatus of the present invention. In FIG. 11, a water supply valve 54, a fire hydrant valve 56, and an automatic pressure regulating valve 58 are provided in the valve housing space, and the emergency head 14 is connected to the head pipe 24 branched from the secondary side of the automatic pressure regulating valve 58 and drawn to the outside.

Pressurized water for fire extinguishing is supplied and also supplied to the emergency awareness head 14 to perform awareness discharge.

  Here, in order to perform the water discharge from the hose with the nozzle and the emergency water discharge from the emergency head 14 separately, a nozzle with an opening / closing lever is used as the nozzle attached to the tip of the hose, and the nozzle is always used. If it is placed in a fire hydrant device in a closed state, it is possible to prevent water from being discharged from the nozzle even if emergency alert water discharge is performed.

  In the present embodiment, by using a normal water discharge valve system as it is, the tactile water discharge can be performed with a simple and low-cost configuration.

  FIG. 12 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant apparatus of the present invention. In FIG. 12, a water supply valve 54, a fire hydrant valve 70 using an electric valve, and an automatic pressure regulating valve 58 are provided in a valve storage space, and the head piping 24 branched from the secondary side of the automatic pressure regulating valve 56 and drawn to the outside. An emergency head 14 is connected.
