Description
[Technical field]
[0001] The present invention relates to a fire hydrant device, and more particularly to a fire hydrant device equipped with an indicator light. [Background technology]
[0002] Conventionally, there are fire hydrant devices installed in tunnels. Such fire hydrant devices have been installed by embedding them in spaces created by cutting out a box from the tunnel wall, but in recent years, tunnels have come to be excavated using the shield tunneling method, and in this case, the inner wall of the tunnel is constructed of steel segments at the same time as the excavation, making it difficult to secure the installation space for the fire hydrant device by cutting out a box from the tunnel wall.
[0003] Therefore, in tunnels excavated using the shield tunneling method, fire hydrant devices are not embedded in the tunnel walls, but are installed in open spaces within the tunnel, such as guard passages (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2017-56020 A Summary of the Invention [Problem to be solved by the invention]
[0005] Fire hydrant devices are provided with indicator lights to indicate the location of the fire hydrant device and push-button transmitter so that the location of the fire hydrant device can be quickly confirmed in the event of a fire, etc. In the case of fire hydrant devices installed in tunnels, due to the nature of the tunnel, it is expected that the indicator lights will be visible to vehicles passing through the lane, and visibility from the side is more important than visibility from the front.
[0006] On the other hand, since the space of the guard passage and the like is relatively limited, the fire hydrant device installed in the tunnel is required to be thin so as to occupy as little space as possible. In order to make the fire hydrant device thin, it is also necessary to shape the indicator light provided on the front side of the housing of the fire hydrant device so that the indicator part protrudes as little as possible from the housing. However, reducing the amount of protrusion of the indicator part from the housing causes a problem in that it becomes difficult to ensure the luminous intensity from the side direction.
[0007] On the other hand, the indicator lights installed in tunnels are mainly visible from the lane, and the closer the fire hydrant device is installed to the lane, the smaller the lateral visible area of the indicator light from the lane. As a result, the closer the fire hydrant device is installed to the lane, the shorter the lateral distance between the observer and the fire hydrant device at which the indicator light can be seen, making it difficult to ensure visibility.
[0008] As a result, when installing a fire hydrant device in a space such as a guard's passage, the device will be installed closer to the lane than in the conventional case where it is installed without a box. This, combined with the reduced amount of protrusion of the indicator light from the housing, reduces the luminous intensity from the side, creating a new problem in that it is more difficult to ensure visibility from the side than when it is installed without a box.
[0009] Therefore, an object of the present invention is to provide a fire hydrant device having improved visibility of an indicator light from the side compared to conventional fire hydrant devices. [Means for solving the problem]
[0010] The present invention relates to A fire hydrant device installed in a tunnel, having a door for mounting an indicator light A housing and Provided on the indicator light mounting door, An indicator light having a display portion; a door opening means for rotating the indicator light mounting door toward one side in the event of a fire; Equipped with The indicator light-mounted door is configured to be opened by the door-opening means at least in the event of a fire and to be held so as to face in a direction opposite to the traveling direction of vehicles traveling through the tunnel, and the door-opening means is configured to automatically open the indicator light-mounted door in response to a fire signal, and the display unit is arranged so that, at least in the event of a fire, substantially the entirety of the display unit is visible from at least one of the lateral sides and faces in a direction opposite to the traveling direction of vehicles traveling through the tunnel. This is a fire hydrant device characterized by the above.

[0018] A first embodiment of the present invention will be described with reference to Fig. 1 to Fig. 4, taking as an example a fire hydrant device 1A installed in an open space such as a guard passage in a tunnel. Note that this embodiment is an example assuming that vehicles passing through the tunnel keep to the left, and when vehicles pass through the tunnel on the right, the device can be installed with the left and right reversed.
[0019] Here, the terms "front," "left," "back," and other terms indicating position and direction used in explaining this invention are used according to the position and direction of the fire hydrant device 1A when it is installed. Also, the side and lateral sides refer to the left and right sides of the fire hydrant 1A when it is installed.
[0020] The fire hydrant device 1A includes a housing 2 and an indicator light 3A. The housing 2 has a side plate 20 on at least one side of the housing. In this embodiment, the housing 2 has a front panel 21, which is a front plate constituting the front side of the housing 2, and a main body 22 provided on the rear side of the front panel 21, and various fire hydrant devices (not shown), a fire hose (not shown) having a fire nozzle attached to its tip, and a fire extinguisher (not shown) are housed inside the housing 2.
[0021] The front panel 21 is provided with a fire hydrant door 23 for taking out the fire hose to the outside of the housing 2, a work door 24 for installing and inspecting the fire hydrant device, and a fire extinguisher door 25 for taking out the fire extinguisher to the outside of the housing 2, and is fitted with a push-button type transmitter 4 for reporting. The main body 22 is substantially box-shaped, and its front side is closed by the front panel 21, and in this embodiment, the side portion on the left side surface side is the side panel 20.
[0022] The indicator light 3A has a display unit 30A and a light-emitting unit (not shown) provided inside the display unit 30A and having LEDs (light-emitting diodes) or the like arranged therein, and is attached to the side plate 20. The display unit 30A is provided so that it can be seen almost entirely from one side, in this embodiment, the left side, at least in the event of a fire. In this embodiment, the fire hydrant device 1A is not installed by cutting out a box from the wall of the tunnel, so the side plate 20 is exposed to the outside, and by providing the indicator light 3A on the side plate 20, it is possible to make the display unit 30A almost entirely visible from one side at least in the event of a fire.
[0023] Moreover, when the fire hydrant device 1A is installed in the tunnel, the display unit 30A is preferably provided so as to face in a direction opposite to the traveling direction of the vehicle traveling through the tunnel at least in the event of a fire, that is, to the left when the vehicle drives on the left side as in this embodiment, and to the right when the vehicle drives on the right side. By doing so, when a fire breaks out in the tunnel, the indicator light 3A becomes easily visible to drivers and others in vehicles traveling in the lane who may be looking for the fire hydrant device 1A.
[0024] In this embodiment, the display unit 30A is formed in a streamlined shape, for example, in a substantially conical shape. This reduces the air resistance of the display unit 30A, prevents dust and other contaminants floating in the tunnel from adhering to the display unit 30A, and maintains the luminosity of the indicator light 3A. The shape of the display unit 30A can be changed as necessary, but when a so-called convex streamlined shape is used as the display unit 30A, the display unit 30A can be provided on the top panel 26 of the main body 22 instead of on one of the sides, so as to maintain the visibility of the indicator light from the side direction.
[0025] Therefore, in the fire hydrant device 1A of this embodiment, an indicator light 3A is provided on the side panel 20, and at least in the event of a fire, substantially the entire display portion 30A of the indicator light 3A is visible from one side, thereby improving the visibility of the indicator light from the side.
[0026] Furthermore, even if the indicator light is made thin, it is installed on the side plate 20, so it is seen from the front by the driver in the vehicle traveling on the roadway in the viewing direction, and visibility is good. Since the indicator light itself does not need to be made thin because it is installed on the side plate of the fire hydrant, it is possible to use an indicator light with a conventional protruding shape. The indicator light 3A installed on the side plate 20 emits a straight light when turned on, so while it has good lateral visibility, it may be dazzling to some viewers. In such a case, a luminance adjustment mechanism is provided to adjust the luminance of the display part 30A of the indicator light 3A. This makes it possible to reduce glare while maintaining visibility.
[0027] A second embodiment of the present invention will be described with reference to Figs. 5 and 6, taking a fire hydrant device 1B installed in a tunnel as an example. Note that, like the first embodiment, this embodiment is also an example assuming that vehicles passing through the tunnel keep to the left. The difference between this embodiment and the first embodiment is that an indicator light mounting door 27 is provided on the housing 2, and instead of providing the indicator light 3A on the side panel 20, an indicator light 3B is provided on the indicator light mounting door 27. The configurations denoted with the same reference numerals as those in the first embodiment are similar to those in the first embodiment, and therefore description thereof will be omitted.
[0028] In the fire hydrant device 1B of this embodiment, the housing 2 is equipped with an indicator light mounting door 27, and the indicator light 3B is provided on the indicator light mounting door 27. In this embodiment, in order to reduce the amount of protrusion of the indicator light 3B from the housing 2, the display unit 30B has a flat shape and is provided so as to be approximately flush with the front surface of the housing 2. Otherwise, it has the same configuration as the display unit 3A, and is provided on the front surface side of the indicator light mounting door 27. The amount of protrusion of the display unit 30B from the housing 2 can be appropriately changed as necessary, and it is also possible to form the display unit 30B in a shape that does not substantially protrude from the housing 2.
[0029] The indicator light mounting door 27 is configured to be opened by a door-opening means (not shown) and rotated toward one side, in this embodiment, toward the left, in the event of a fire. This makes it possible to view the display unit 30B almost entirely from at least one side in the event of a fire. In this embodiment, the indicator light mounting door 27 rotates toward the left for the same reason as in the first embodiment (see paragraph
[0023] ).
[0030] In this embodiment, the indicator light mounting door 27 is configured to rotate by about 90 degrees and be held by the door opening means so that the display unit 30B faces the direction opposite to the traveling direction of the vehicles traveling through the tunnel at least in the event of a fire, as in the first embodiment. The indicator light mounting door 27 is provided integrally with the fire extinguisher door 25.
[0031] As the door-opening means, a known means can be appropriately used, but for example, an actuator or the like can be provided as the door-opening means, and the indicator light mounting door 27 can be rotated toward one of the lateral sides by linear or rotary motion of the actuator or the like. Also, the indicator light mounting door 27 can be manually opened by directly operating a handle 28 provided on the indicator light mounting door 27. In this embodiment, the indicator light mounting door 27 is integrated with the fire extinguisher door 25, so the fire extinguisher door 25 is also rotated in the same direction by the door-opening means.
[0032] In this embodiment, the fire hydrant device 1B is capable of communicating with or connected to an automatic fire alarm system including a detector that detects a fire in the tunnel and a disaster prevention receiving panel (not shown; hereinafter also referred to as the receiving panel). After a fire signal is transmitted to the receiving panel upon activation of a transmitter 4 provided in the fire hydrant device 1B and / or detection of a fire by various devices including detectors provided in the tunnel, the receiving panel sends a signal directly or indirectly to the door-opening means, and the door-opening means is configured to automatically open the indicator light mounting door 27 in response to the signal.
[0033] Therefore, in the fire hydrant device 1B of this embodiment, when the receiving panel receives a fire signal, a signal is sent from the receiving panel to the door-opening means, and the signal causes the door-opening means to rotate the indicator light mounting door 27 toward one of the sides, making almost the entire display section 30B of the indicator light 3B visible from one side at least in the event of a fire, thereby improving the visibility of the indicator light from the side.
[0034] Furthermore, as in this embodiment, by automatically opening the indicator light mounting door 27 in the event of a fire, it becomes easier for the driver and others to detect the abnormality, the visibility of the indicator light can be improved, and early evacuation becomes possible.
[0035] Furthermore, in this embodiment, the indicator light mounting door 27 is formed integrally with the fire extinguisher door 25, so that in the event of a fire, the fire extinguisher door 25 is opened together with the indicator light mounting door 27, making it possible to quickly find or remove the fire extinguisher from the housing 2, and making it possible to start initial fire extinguishing activities more quickly.
[0036] Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit and scope of the invention.
[0037] (1) In the above embodiment, the fire hydrant device 1A and the fire hydrant device 1B installed in a tunnel have been described as examples. However, the present invention is also applicable to fire hydrant devices installed in places other than tunnels.
[0038] (2) It is also possible to provide multiple indicator lights in the fire hydrant apparatus 1A or the fire hydrant apparatus 1B. For example, in the first embodiment, a second indicator light (not shown), for example an indicator light of the same form as the indicator light 3A, can be provided on the side panel 29 of the side portion on the other side surface side of the main body 22. Also, in the second embodiment, a second indicator light can be provided on the back side of the indicator light mounting door 27.
[0039] In this way, at least in the event of a fire, substantially the entirety of at least either display unit 30A or display unit 30B or the display unit of the second indicator light can be seen from both sides, and it is possible to ensure visibility of the indicator light, for example, even for evacuees who get off the vehicle and are evacuating in the opposite direction to the vehicle's traveling direction through a guard passage or the like.
[0040] In the above embodiment, it is of course possible to further provide an indicator light (not shown) on the front panel 21, for example an indicator light of the same form as the indicator light 3B, in the same manner as in a conventional fire hydrant device.
[0041] (3) In the second embodiment, the indicator light mounting door 27 can be provided separately from the fire extinguisher door 25. In this case, the indicator light mounting door 27 and the fire extinguisher door 25 can be connected to each other and the fire extinguisher door 25 can be opened together with the indicator light mounting door 27 by the door-opening means, but it is also possible to open only the indicator light mounting door 27 by the door-opening means.
[0042] (4) In the second embodiment described above, the indicator light mounting door 27 opens to the left or right. However, for example, in a fire hydrant device embedded in a guard passage, the indicator light mounting door may open upward toward one of the sides, or, if necessary, may open downward toward the same direction.
[0043] (5) When a fire occurs, the display units 30A and 30B may be configured to light up or flash, for example, when triggered by a signal from a receiving panel of an automatic fire alarm system or activation of the transmitter 4. This, combined with improved visibility from the side of the display units 30A and 30B, makes it easier for the driver or the like to detect abnormalities, and can further improve the visibility of the indicator lights 3A and 3B.
