Description

[Technical Field]

[0001] The present invention relates to a fire hydrant device installed in a tunnel and housing a fire hose, a fire extinguisher, etc. [Background technology]

[0002] Conventionally, fire hydrants have been installed as emergency tunnel equipment in tunnels such as expressways and expressways. A fire hydrant system consists of a housing with a fire hydrant door, a fire hose with a nozzle attached to the end, and valves including a fire hydrant valve, housed in a fire hydrant housing section, and a fire extinguisher housing section with a fire extinguisher door, which houses, for example, two fire extinguishers. Furthermore, fire hydrant systems are generally installed by embedding boxes into the tunnel wall at intervals of, for example, 50 meters along the length of the tunnel.

[0003] However, in tunnels constructed using methods such as shield tunneling, the structure of the tunnel body makes it difficult to cut out a box in the tunnel wall and install a fire hydrant device by embedding it in place, due to the cost and effort involved, so the fire hydrant must be installed in an exposed position in the guard's passage.

[0004] Furthermore, in order to install the fire hydrant device on the tunnel wall surface without removing the box, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a stand installed on the tunnel wall surface.In this case, the stand is composed of a main support part fixed to the wall surface and a position-maintaining member that maintains the position of the fire hydrant device (Patent Document 2).

[0005] Furthermore, since wall-mounted fire hydrant devices have issues such as the time and labor required to install them on the tunnel wall, it is being considered to use a so-called stationary structure in which the fire hydrant device is attached and fixed in an exposed state to a stand installed on the road surface of the guard passage, which is easier to install.

[0007] In the case of a stationary structure in which the fire hydrant device is attached and fixed in an exposed state to a stand installed on the road surface of the monitor's passage, the height of the stand is determined so that the height of the operating part of the transmitter etc. installed on the fire hydrant device is within the legally specified range or at a height that is easy for the user to operate from their position on the road surface.In such cases, a height in the range of, for example, 20 to 40 cm is required.

[0008] Furthermore, the mounting frame is a box-frame structure made of steel, for example, angle iron, and the angle iron is exposed, and it is installed at a certain height below the red-painted fire hydrant device, which makes it look unsightly. Furthermore, while the interior of the mounting frame can be used as storage space for the equipment and devices associated with the fire hydrant device, such as wiring cables, piping, and valves, dust from inside the tunnel can accumulate over time and cause contamination, which can impair the durability of the stored equipment and devices.

[0009] The object of the present invention is to provide a fire hydrant device that improves the appearance of a stand that places the fire hydrant device in an exposed state at a predetermined height above a guard's walkway, prevents the stand and the equipment and devices stored within the stand from being soiled, and improves durability.

[0021] (Structure of the mounting frame) When the stand is installed on the road surface at the installation location, the side shape in the depth direction is an inverted trapezoid with the top side longer than the bottom side.

[0022] (equipment storage on the stand) The frame has predetermined equipment attached to the fire hydrant device placed or stored inside it. [Effects of the Invention]

[0023] (Effect of fire hydrant equipment) The present invention relates to a fire hydrant device in which a housing is fixed to a mount installed on the road surface of a guard passageway provided along the wall of a tunnel with a road, and a mount cover is provided to cover the front and both side surfaces of the mount, so that the angle iron of the mount is not exposed below the fire hydrant device, and the finished appearance of the equipment is appropriate and does not deteriorate. In addition, by covering the opening of the mount with the mount cover, it is possible to suppress and prevent contamination of equipment such as pipes, wiring cables, and valves arranged or stored in the housing by dust in the tunnel space, thereby improving durability.

[0024] (Effect of the mount cover that is freely movable on the housing side) In addition, the mount cover is provided with a front mount cover corresponding to the front of the mount and a pair of side mount covers corresponding to each of the two side surfaces of the mount, which can be moved freely on the housing side. Therefore, when the fire hydrant device is transported to the installation location in the tunnel and installed on the mount, the mount cover does not get in the way and does not impair the workability involved in installation.

[0025] The front pedestal cover and the pair of side pedestal covers can be moved toward the pedestal to cover the front and both sides of the pedestal, or moved toward the housing to open the front and both sides of the pedestal, making it easy to position the pedestal covers to cover the openings of the pedestal. Furthermore, by moving the pedestal covers toward the housing to open the openings of the pedestal, it is easy to work on the equipment and devices stored in the pedestal.

[0026] (Effect of the housing support structure of the stand cover placed on the housing side) In addition, the front base cover is pivotally supported on the bottom edge of the front of the housing so that it can rotate freely in the vertical direction, and can be rotated toward the base to cover the front of the base, or rotated toward the housing to open the front of the base, while the pair of side base covers are pivotally supported on the bottom edges of both sides of the housing so that they can rotate freely in the vertical direction, and can be rotated toward the base to cover each of both sides of the base, or slide toward the housing to open each of both sides of the base, allowing the front base cover and the pair of side base covers to be easily moved toward the housing or the housing.

[0027] (Effect of the sliding structure of the stand cover placed on the chassis side) In addition, the front frame cover is supported on the outside of the front surface of the housing on the bottom side of the housing so that it can slide freely in the vertical direction, and is held in a position where it slides toward the frame to cover the front surface of the frame, or slides toward the housing to open the front surface of the frame, and the pair of side frame covers are supported on the outside of each of both side surfaces on the bottom side of the housing so that it can slide freely in the vertical direction, and is held in a position where it slides toward the frame to cover each of both side surfaces of the frame, or slides toward the housing to open each of both side surfaces of the frame, so that the front frame cover and the pair of side frame covers can be easily moved toward the housing or the frame, and because the front frame cover and the pair of side frame covers slide up and down along the surfaces of the housing and the frame, they will not protrude into the guard passage and obstruct passage.

[0028] (Effect of the mount cover that is freely movable on the mount side) The gantry cover includes a front gantry cover corresponding to the front of the gantry and a pair of side gantry covers corresponding to each of the two sides of the gantry, and these gantry covers are movable toward the gantry. The front gantry cover and the pair of side gantry covers can be moved toward the gantry to a position covering the front and both sides of the gantry, or moved toward the housing to a position opening the front and both sides of the gantry, thereby enabling the gantry cover to be easily positioned to cover the opening of the gantry. Furthermore, by moving the front gantry cover and the pair of side gantry covers toward the housing to open the opening of the gantry, it is possible to easily perform work on the equipment and devices stored in the gantry. Furthermore, because the front gantry cover and the pair of side gantry covers are positioned on the gantry side, they do not affect the structure of the housing.

[0029] (Effect of the first pivoting mechanism of the stand cover placed on the stand side) In addition, the front frame cover is pivotally supported on the upper edge of the front of the frame so that it can rotate freely in the vertical direction, and is held in a position where it can rotate toward the frame to cover the front of the frame, or rotate toward the housing to open the front of the frame, and the pair of side frame covers are pivotally supported on each of the upper edges of both sides of the frame so that it can rotate toward the frame to cover each of both side faces of the frame, or rotate toward the housing to open both side faces of the frame, so that the front frame cover and the pair of side frame covers can be easily moved toward the housing or the frame, just as when the front frame cover and the pair of side frame covers are pivotally supported on the housing side.

[0030] (Effect of the second pivoting mechanism of the base cover located on the base side) In addition, the front platform cover is pivotally supported on the lower edge of the front of the platform so that it can rotate freely in the vertical direction, and can be rotated toward the platform to cover the front of the platform, or rotated toward the road surface side of the monitor's passage to open the front of the platform.The pair of side platform covers are pivotally supported on the lower edge of each of both sides of the platform so that they can rotate freely in the vertical direction, and can be rotated toward the platform to cover each of both sides of the platform, or rotated toward the road surface side of the monitor's passage to open each of both sides of the platform.This allows the front platform cover and the pair of side platform covers to be easily moved toward the housing side or the road surface side of the monitor's passage.

[0031] (Effect of the sliding structure of the stand cover placed on the stand side) In addition, the front frame cover is supported on the outside of the front of the frame so that it can slide freely in the vertical direction, and is held in a position where it slides toward the frame to cover the front of the frame, or slides toward the housing to open the front of the frame, and the pair of side frame covers are supported on the outside of each of both side faces of the frame so that it can slide freely in the vertical direction, and is held in a position where it slides toward the frame to cover each of both side faces of the frame, or slides toward the housing to open each of both side faces of the frame.This allows the front frame cover and the pair of side frame covers to be easily moved toward the housing or the frame, just as if the front frame cover and the pair of side frame covers were positioned so that they could slide freely toward the housing, and further, because the front frame cover and the pair of side frame covers slide up and down along the surfaces of the housing and the frame, they will not protrude into the guard passage and obstruct passage.

[0032] (Effect of dividing the front rack cover) In addition, the front stand cover can be divided longitudinally to the left and right, for example, into two parts, which reduces the width of each cover, making it easier to open and close the stand cover, and also making it possible to open the stand cover of the part of the stand that requires work and perform the work.

[0033] (Effect of the text on the front cover) In addition, the front mount cover has the word "fire hydrant" written horizontally on the front side corresponding to the fire hydrant equipment storage section of the housing, and the word "fire extinguisher" written horizontally on the front side corresponding to the fire extinguisher storage section of the housing.As a result, in addition to the words "fire hydrant" and "fire extinguisher" being displayed on the front of the housing, the words "fire hydrant" and "fire extinguisher" are also displayed on the front mount cover, expanding the visible range of the emergency equipment names and improving visibility.

[0034] (Effect of the mounting structure) Furthermore, when the mount is installed on the road surface at the installation location, the side shape in the depth direction is an inverted trapezoid with the top side longer than the bottom side, which allows the mount to be installed in contact with or close to the tunnel wall, which has an arc cross section, and reduces the risk of the fire hydrant device attached and fixed on the mount protruding into the guard's passage.

[0035] (Effect of storing equipment on the rack) Furthermore, by arranging or storing predetermined equipment attached to the hydrant device inside the mount, it becomes possible to effectively utilize space by storing, for example, wiring and piping for the hydrant device in the storage space inside the mount. Therefore, by storing the attached equipment such as wiring (cables), piping, and valves on the mount side, the fire hydrant device can reduce the overall installation space on the housing side and make it thinner, and it becomes possible to suppress the amount of protrusion of the monitor's walkway above the road surface.

[0037] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fire hydrant device according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0038] [Basic concept of the embodiment] First, a basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device in which a fire hydrant device, an electrical device, a terminal box, and a fire extinguisher are arranged in a housing.

[0039] Here, a "fire hydrant device" is a type of emergency equipment installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways, and is a housing installed in the area subject to fire extinguishing, in which fire hydrant equipment such as fire hoses, electrical equipment such as red indicator lights and transmitters on electrical doors, terminal boxes, and fire extinguishers are placed or stored, and the concept includes fire hydrant facilities in which fire hydrant devices are installed.

[0040] The fire hydrant device is installed in an exposed state at a predetermined height above the road surface of a guard passageway that is provided along the interior wall of a tunnel that has a road. Here, the "predetermined height" refers to a height that allows the fire hydrant device to be installed in a position close to or in contact with the tunnel wall, and is installed at the predetermined height, for example, by attaching and fixing the housing to the top of a stand installed on the road surface of the guard passageway, or by attaching and fixing the housing to the front part of a stand installed on the tunnel wall above the road surface of the guard passageway, which is on the road side.

[0041] Furthermore, the term "mounting" refers to a structure that supports an object using pillars, beams, etc., and although specific examples are not shown, it includes concepts such as a support base, a foundation, a base, a seat, a base, etc. Furthermore, the mounting of this embodiment is intended to be a structure in which steel materials, for example, angle irons, are connected to form a box frame shape.

[0042] In this embodiment, the fire hydrant device has a housing attached and fixed to a base installed on the road surface of a guard passageway that runs along the wall of a tunnel with a road, and base covers are placed to cover the front and both side surfaces of the base. Here, the "base cover" refers to a plate-like member that is placed to cover the front and both side surfaces of a base made of angle bars connected to form a box frame, and is a concept that includes plate-like members made of metal or synthetic resin. The "base cover" is also composed of a front base cover that corresponds to the front of the base and a pair of side base covers that correspond to each of the both side surfaces of the base.

[0043] The fire hydrant device of this embodiment is divided into first to fifth embodiments depending on the arrangement structure of the pedestal cover. The arrangement structure of the pedestal cover is divided into first to fifth embodiments depending on whether the pedestal cover is movably provided on the housing side of the fire hydrant device or movably provided on the pedestal side, and also depending on whether the pedestal cover is rotatably provided or slidably provided.

[0044] In a first embodiment of the fire hydrant device, a mount cover is rotatably supported on the housing side of the fire hydrant device, and for example, the front mount cover is rotatably supported on the bottom edge of the front of the housing in the vertical direction and is held in a position where it rotates toward the mount side to cover the front of the mount, or rotates toward the housing side to open the front of the mount. Also, a pair of side mount covers are rotatably supported on the bottom edges of both sides of the housing in the vertical direction and are held in a position where it rotates toward the mount side to cover each of the both side sides of the mount, or rotates toward the housing side to open each of the both side sides of the mount.

[0045] In a second embodiment of the fire hydrant device, a mount cover is rotatably supported on the upper edge of the mount of the fire hydrant device, for example, the front mount cover is rotatably supported on the upper edge of the front of the mount in the vertical direction and is held in a position where it rotates toward the mount to cover the front of the mount, or rotates toward the housing to open the front of the mount. Also, a pair of side mount covers are rotatably supported on the upper edges of both side surfaces of the mount in the vertical direction, and are held in a position where it rotates toward the mount to cover both side surfaces of the mount, or rotates toward the housing to open both side surfaces of the mount.

[0046] In a third embodiment of the fire hydrant device, a mount cover is pivotally supported on the lower edge of the mount of the fire hydrant device. For example, the front mount cover is pivotally supported on the lower edge of the front surface of the mount so as to be pivotable in the vertical direction, and is held in a position where it rotates toward the mount to cover the front surface of the mount, or rotates toward the road surface of the guard passage to open the front surface of the mount. Also, a pair of side mount covers are pivotally supported on the lower edges of each of the both side surfaces of the mount so as to be pivotal in the vertical direction, and is held in a position where it rotates toward the mount to cover each of the both side surfaces of the mount, or rotates toward the road surface of the guard passage to open each of the both side surfaces of the mount.

[0047] In a fourth embodiment of the fire hydrant device, a mount cover is slidably supported on the housing side of the fire hydrant device, and for example, the front mount cover is supported on the outside of the front surface of the housing on the bottom side of the housing so as to be slidable in the vertical direction, and is held in a position where it slides toward the mount side to cover the front surface of the mount, or a position where it slides toward the housing side to open the front surface of the mount. Also, a pair of side mount covers are supported on the outside of each of both side surfaces on the bottom side of the housing so as to be slidable in the vertical direction, and is held in a position where it slides toward the mount side to cover each of both side surfaces of the mount, or a position where it slides toward the housing side to open each of both side surfaces of the mount.

[0048] In a fifth embodiment of the fire hydrant device, a mount cover is slidably supported on the mount side of the fire hydrant device, and for example, the front mount cover is supported on the outside of the front surface of the mount so as to be slidable in the vertical direction, and is held in a position where it slides toward the mount side to cover the front surface of the mount, or slides toward the housing side to open the front surface of the mount. Also, a pair of side mount covers are supported on the outside of each of both side surfaces of the mount so as to be slidable in the vertical direction, and is held in a position where it slides toward the mount side to cover each of both side surfaces of the mount, or slides toward the housing side to open each of both side surfaces of the mount.

[0049] The front frame cover can be divided into two parts, for example, in the left and right longitudinal direction as required.

[0050] In addition, the front mounting cover has the word "fire hydrant" displayed, for example, horizontally, on the front side corresponding to the fire hydrant equipment storage section of the fire hydrant device housing, and the word "fire extinguisher" displayed, for example, horizontally on the front side corresponding to the fire extinguisher storage section of the housing, thereby improving the visibility of the emergency equipment name.

[0051] Furthermore, when the mounting base is installed on the road surface at the installation location, the side shape in the depth direction is an inverted trapezoid with the top side longer than the bottom side, which allows the mounting base to be installed in contact with or close to the tunnel wall, which has an arc-shaped cross section, and makes it possible to reduce the risk of the fire hydrant device attached and fixed on the mounting base jumping out into the guard's passage.

[0052] In addition, the stand is used to place or store the specified equipment attached to the fire hydrant device. For example, by storing equipment such as wiring (cables), piping, and valves attached to the fire hydrant device on the stand side, space can be used effectively, the overall installation space on the housing side can be reduced, and the thickness can be made thinner, making it possible to limit the amount by which the fire hydrant device's monitor's walkway protrudes above the road surface.

[0053] Specific embodiments will be described below. In the specific embodiments shown below, "a fire hydrant device is attached and fixed to a platform installed above the guard passage in the tunnel," and the embodiments of the fire hydrant device will be described separately as the first to fifth embodiments described above.

[0058] 1(B), the housing of the fire hydrant device 10 of this embodiment is divided into a first housing 11a and a second housing 11b. A decorative frame 13a is attached to the front of the first housing 11a. The door opening of the decorative frame 13a is divided into upper and lower halves, with a fire hydrant door 12 that opens downward by hinge 12a located on the lower side of the door opening and a maintenance door 14 that opens upward by hinge 14a located on the upper side of the door opening. A fire hydrant device storage compartment inside the first housing 11a stores predetermined fire hydrant devices, including fire hoses and valves such as a fire hydrant valve.

[0059] A decorative frame 13b is attached to the front of the second housing 11b. The decorative frame 13b has two door openings, with an electrical door 18 that opens laterally to the right on hinge 18a located in the right door opening, and an auxiliary door 20 that opens laterally to the left on hinge 20a located on the left, allowing access to the internal terminal boxes 26a and 26b. The electrical door 18 is provided with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 25, and a telephone jack is provided inside.

[0060] The red indicator light 22 is always lit, allowing the installation location of the fire hydrant device 10 to be confirmed from a distance. When a fire breaks out and the transmitter 24 is pressed to turn on the push button switch, a transmission signal is sent, which is received by a disaster prevention receiving panel installed in an electrical room or the like and issues a fire alarm. The fire hydrant device 10 receives a response signal from the disaster prevention receiving panel, causing the red indicator light 22 to flash and the response lamp 25 to light up.

[0061] A fire extinguisher door 16 that opens sideways to the left on hinges 16a is provided in the door opening on the left side of decorative frame 13b, and for example, two fire extinguishers can be stored inside fire extinguisher door 16. A viewing window 17 is provided below fire extinguisher door 16, allowing the presence or absence of a fire extinguisher to be confirmed from the outside.

[0062] (a2. Installation of fire hydrant equipment) The installation of fire hydrants in tunnels will be explained in more detail below. A road 46 is constructed in the longitudinal direction (left and right direction) of the tunnel below the cylindrical (circular cross section) tunnel body constructed using the shield tunneling method, and a guard passage 35 is constructed at a predetermined height above the road 46 below the tunnel wall 26 along the rear side of the road 46.

[0063] Since it is difficult to cut out a box from the tunnel wall 26 constructed by the shield construction method to install the fire hydrant device 10, the mount 30 is installed close to the tunnel wall 26 on the road surface of the monitor's passage 35, and the first housing 11a and second housing 11b, which are connected, are attached and fixed to the mount 30, thereby installing the fire hydrant device 10. Here, the height H1 of the mount 30 is set so that the height from the road surface of the monitor's passage 35 to the transmitter 24 installed on the fire hydrant device 10 is within the legally specified range of 800 mm to 1500 mm.

[0064] 1(A), the side shape of the mount 30 of this embodiment is an inverted trapezoid with the upper side longer than the lower side, and the rear side is an inclined surface that slopes diagonally downward along the curved shape of the tunnel wall surface 26. The first housing 11a and second housing 11b connected to the fire hydrant device 10 are attached and fixed to the upper end surface of the mount 30.

[0065] A front mount cover 32 is disposed on the front of the mount 30, covering and closing the front opening of the mount 30. On the right front side of the front mount cover 32, corresponding to the first housing 11a in which the fire hydrant equipment is stored, the character string "fire hydrant" indicating the name of the equipment is displayed horizontally. On the left front side of the front mount cover 32, corresponding to the second housing 11b in which the fire extinguisher is stored, the character string "fire extinguisher" indicating the name of the equipment is displayed horizontally. On both side surfaces of the housing 30, side mount covers 34 are disposed, covering and closing the side openings of the mount 30.

[0066] (a3. Installation height and thinness of fire hydrant equipment) The installation height and thinness of the fire hydrant device will be explained in more detail below. In order to reduce the restriction on the passage width caused by the protrusion (projection) of the fire hydrant device 10, which is installed on the road surface of the guard passage 35 by the mount 30, from the tunnel wall surface 26, the installation height of the fire hydrant device 10 has been optimized, and at the same time, the fire hydrant device 10 has been made as thin as possible.

[0067] First, since the installation height of the fire hydrant device 10 is determined by the mounting base 30, optimization of the height H1 of the mounting base 30 will be described in more detail. Figure 2 shows a schematic diagram of the installation state of the fire hydrant device in a tunnel cross section. The tunnel wall surface 26 on which the fire hydrant device 10 is installed has a circular cross section, and in Figure 2(A), the height H1 of the mounting base 30 is set so that the horizontal housing center line SL2 passing through the center of the height direction of the fire hydrant device 10 installed on the monitor passage 35 is as close as possible to the tunnel center line SL1 in the horizontal direction from the tunnel center (center of the circular cross section) P.

[0068] In this case, the closer the housing center line SL2 is to the tunnel center line SL1, the more the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 26 can be reduced.

[0069] 2(B) shows a case where the height H1 of the mount 30 is set so that the housing center line SL2 coincides with the tunnel center line SL1. In this case, the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 26 can be minimized. However, the height H1 of the mount 30 should be adjusted within the possible range, taking into account factors such as the ease of removing the fire extinguisher.

[0070] Next, a more detailed explanation will be given of how the fire hydrant device 10 can be made thinner. Of the devices housed in the fire hydrant device 10, the fire extinguisher housed in the second housing 11b is the device with the largest size in the front-to-rear direction, and the fire hydrant device 10 can be made thinner as long as the width (thickness in the front-to-rear direction) of the fire hydrant device is up to the minimum value that allows the fire extinguisher to be housed in the second housing 11b, so the width of the fire hydrant device 10 is set to a predetermined width that corresponds to the outer diameter of the fire extinguisher housed in the second housing 11b.

[0071] The outer diameter of the fire extinguisher is about 150 to 160 mm, and if a gap is secured so that the stored fire extinguisher does not come into contact with the second housing 11b, the minimum width of the fire hydrant device 10 will be, for example, within a range of about 180 to 200 mm, and the width of the fire hydrant device 10 is set to a predetermined width within that range. In contrast, the width of a conventional fire hydrant device 10 that is installed by cutting a box out of the wall surface of a tunnel body and embedding it in place is about 300 mm, so the width of the fire hydrant device 10 of this embodiment can be made two-thirds or less of the conventional width, allowing the fire hydrant device 10 to be made thinner.

[0072] (a4. Configuration compatible with thinner fire hydrant devices) If the fire hydrant device 10 is thinned to a predetermined width in the range of about 180 to 200 mm corresponding to the outer diameter of the fire extinguisher, it becomes difficult to store a fire hose of a predetermined length, for example, a 30 m shape-retaining hose, in an inwardly coiled state in the first housing 11a, as in conventional fire hydrant devices. Therefore, in this embodiment, by increasing the width (width in the left-right direction) of the first housing 11a, it becomes possible to store a shape-retaining hose of the same predetermined length as in conventional fire hydrant devices in an inwardly coiled state.

[0073] Furthermore, as the fire hydrant device 10 becomes thinner, it becomes difficult to place a terminal box on the rear surface of the housing behind the fire extinguisher storage section where the fire extinguisher is stored, as in conventional fire hydrant devices. Therefore, in this embodiment, the width (length in the left-right direction) of the second housing 11b is increased to a width that allows for the storage of the fire extinguisher as well as the placement of electrical equipment and a terminal box.

[0074] (a5. Fire hydrant equipment stand) The fire hydrant device mount will be described in more detail below. Figure 3 is a perspective view of the mount on which the fire hydrant device is attached and fixed. Mount 30 is made, for example, by cutting angle irons or the like to a predetermined length and welding them into a box shape, and the angle irons or the like are arranged so that when viewed from the side, it forms an inverted trapezoid with the top side longer than the bottom side.

[0075] Mounting holes 31, each pair consisting of two front and two rear holes, are formed in three locations along the longitudinal direction of the top surface on the upper end surface of the mount 30. The mounting holes 31 are formed at positions corresponding to the mounting holes on the bottoms of the first housing 11a and the second housing 11b of the fire hydrant device 10, and the first housing 11a and the second housing 11b are attached and fixed to the mount 30 by inserting bolts and fitting nuts into the holes while aligning them.

[0076] (a6. Structure of the first housing) The structure of the first housing 11a will be described in more detail. In this description, reference will be made to Fig. 4, which shows the internal structure of the fire hydrant device from the front with the hydrant door and maintenance door open, Fig. 5, which shows the internal structure of the fire hydrant device in cross section as viewed from above, and Fig. 6, which shows a cross section of the hose storage section of the first housing as viewed from the right side. Note that Fig. 5 is a cross section indicated by section line aa in Fig. 4, and Fig. 6 is a cross section indicated by section line bb in Fig. 4. Furthermore, Fig. 6 shows the side view of the fire hydrant door 12 in Fig. 4.

[0077] The interior of the first housing 11a, which serves as the storage section for the fire hydrant equipment, is divided into a valve storage section 50a and a hose storage section 50b. In the valve storage section 50a, a water supply hydrant 52 is connected to a water supply pipe 48 drawn in through the frame 30. The pipe to the water supply hydrant 52 branches downward, and at the end of the branch, a fire hydrant valve 54 and an automatic pressure adjusting valve 56 are provided, and subsequently, a shape-retaining fire hose 60 is connected.

[0078] The hydrant valve 54 is opened and closed by a hydrant valve opening / closing lever 58, and when the hydrant valve opening / closing lever 58 is opened or closed, the hydrant valve 54 is remotely opened or closed by a known wire link mechanism. When the hydrant valve opening / closing lever 58 is opened or closed, a pump start interlock switch provided on the operation box turns on or off. In addition, a pump start switch 64 for use by the fire brigade is provided on the upper right of the hydrant 52.

[0079] A hose storage frame 62 is provided in the hose storage section 50b, and the fire hose 60, drawn in from below, is stored in a clockwise or counterclockwise inward coiled state. The hose storage frame 62 has a wider width to accommodate the increased width of the first housing 11a due to the slimming of the fire hydrant device 10. This allows the same predetermined length of fire hose 60 to be stored with fewer coils than in conventional fire hydrant devices. A nozzle 68 is attached to the tip of the fire hose 60 drawn out through a hose guide 66, and the nozzle 68 is detachably held in a nozzle holder 70. A cable rack 49 for passing cables is disposed above the first housing 11a, and a cable drawn in from outside can be connected to the terminal boxes 26a, 26b on the second housing 11b side via the cable rack 49.

[0080] (a7. Structure of the second housing) The second housing 11b is divided into an electrical equipment side and a fire extinguisher housing side. First, the structure of the electrical equipment side of the second housing 11b will be described in more detail. As shown in Figures 4 and 5, an electrical equipment door 18 that opens sideways to the right on hinges 18a is located in the door opening on the right side of the second housing 11b. From top to bottom, the electrical equipment door 18 is equipped with a red indicator light 22, a transmitter 24, and an answer lamp 25, and a telephone jack 28 is located inside the electrical equipment door 18.

[0081] Here, of the electrical equipment, the red indicator light 22 has the largest size in the front-to-rear direction inside the second housing 11b, and its size is approximately 120 mm. Therefore, even if the fire hydrant device 10 is made thinner to a predetermined width in the range of approximately 180 to 200 mm, each electrical equipment can be arranged while ensuring space for the cables pulled in from the first housing 11a side.

[0082] 4 and 5, terminal boxes 26a and 26b are disposed vertically on the rear surface of the second housing 11b inside the second housing 11b opposite the auxiliary door 20. The auxiliary door 20 is opened together with the electrical door 18 to form an access opening when connecting wiring cables to the terminal boxes 26a and 26b.

[0083] Terminal boxes 26a and 26b are composed of a box body and a lid member, and when placed in second housing 11b, their vertical (top and bottom) x horizontal (left and right) x depth (front and back) dimensions are approximately 220 mm x 140 mm x 80 mm.

[0084] Therefore, even if the fire hydrant device 10 is thinned to a predetermined width in the range of approximately 180 to 200 mm, the depth (front to back) of the terminal boxes 26a, 26b is approximately 80 mm, so sufficient space is secured within the second housing 11b to arrange the terminal boxes 26a, 26b. Furthermore, because the terminal boxes 26a, 26b are arranged in positions close to electrical equipment such as the red indicator light 22 arranged on the first door 18, short wiring can be used to connect the terminal boxes 26a, 26b to the electrical equipment.

[0085] Depending on the fire hydrant device, a transmission unit may be placed to send and receive the fire notification signal from the transmitter 24 located on the electrically equipped door 18 and the response signal to the response lamp 25 via a transmission line between the device and the disaster prevention receiving panel, and sufficient space is provided within the second housing 11b to accommodate the transmission unit in addition to the terminal boxes 26a, 26b.

[0086] Next, the structure of the fire extinguisher storage side of second housing 11b will be described in more detail. As shown in Figures 4 and 5, a space is provided inside fire extinguisher door 16 of second housing 11b that can store two fire extinguishers 72 with an outer diameter of approximately 150 to 160 mm. Also, as mentioned above, in order to make fire hydrant device 10 thinner, the width of fire hydrant device 10 is set to a predetermined width in the range of 180 to 200 mm that corresponds to the outer diameter of fire extinguisher 72. This ensures gaps of approximately 15 to 25 mm in front and behind stored fire extinguisher 72, allowing fire extinguisher 72 to be stored without coming into contact with second housing 11b.

[0087] [b. Mounting cover arrangement structure of the first embodiment] The mount cover arrangement structure of the first embodiment will be described in more detail with reference to Fig. 7, which shows a first embodiment of the cover arrangement structure in which the mount cover is rotatably arranged on the housing side of the fire hydrant device, Fig. 8, which shows the arrangement structure of the front mount cover and the side mount cover relative to the bottom side of the housing, and Fig. 9, which shows the hinged rotation structure of the mount cover relative to the bottom of the housing.

[0088] Here, Fig. 7(A) shows the state in which the casing of the fire hydrant device is in the process of being attached and fixed to the pedestal, and Fig. 7(B) shows the state in which the casing of the fire hydrant device has been attached and fixed to the pedestal. Also, Fig. 8(A) shows the state before the casing cover held on the casing side is placed on the pedestal side, Fig. 8(B) shows a cross section taken along the cutting line cc in Fig. 8(A), Fig. 8(C) shows the state before the side casing cover held on the casing side is placed on the pedestal side, and Fig. 8(D) shows the structure in which the front casing cover is divided into two parts.

[0089] 7(A), in this embodiment, the front frame cover 32 is pivotally supported by hinges 36 on the front bottom edges of the first housing 11a and the second housing 11b of the fire hydrant device 10 so as to be freely rotatable in the vertical direction. As shown in FIG. 9, the pivotal support of the front frame cover 32 by the hinges 36 is structured such that, for example, one mounting plate 36b of the hinge 36 is fixed by screws to a notch 40 formed in the lower end surface of the decorative panel 13a, and the front frame cover 32 is fixed by screws to the other mounting plate 36a.

[0090] The front frame cover 32 is rotated toward the housing and held in contact with the front surfaces of the decorative panels 13a and 13b until the fire hydrant device 10 is carried into the installation location in the tunnel. The method of holding the front frame cover 32 to the front surfaces of the decorative panels 13a and 13b is arbitrary, but for example, as shown in Fig. 7(B), the front frame cover 32 is held by adhesion using a magnetic sheet 38 arranged on the surface of the front frame cover 32. In addition to adhesion using the magnetic sheet 38, if the decorative panels 13a and 13b are made of a non-magnetic material such as stainless steel, the front frame cover 32 may be held in contact with the front surfaces of the decorative panels 13a and 13b using adhesive tape or the like.

[0091] In this way, the front frame cover 32 is held on the housing side of the fire hydrant device 10, so that the work of transporting the fire hydrant device 10 to the installation site is not hindered by the holding of the front frame cover 32. Furthermore, because the front frame cover 32 is held on the outer surface of the housing with its back surface exposed, there is no particular problem even if it hits an object and is slightly scratched.

[0092] A side frame cover 34 is pivotally supported by a hinge 36 on the bottom edge of the right side of the first housing 11a of the hydrant device 10 so as to be freely rotatable in the vertical direction, and until it is transported to the installation location in the tunnel, it rotates toward the housing and is held in contact with the right side of the housing by a magnetic sheet 38 or adhesive tape arranged on the surface of the side frame cover 34. Similarly, a side frame cover 34 is pivotally supported by a hinge 36 on the bottom edge of the left side of the second housing 11b of the hydrant device 10 so as to be freely rotatable in the vertical direction, and until it is transported to the installation location in the tunnel, it rotates toward the housing and is held in contact with the left side of the housing by the magnetic sheet 38 or adhesive tape. Here, the shape of the side frame cover 34 is trapezoidal, corresponding to the trapezoidal shape of the housing 30, whose top side is longer than its bottom side.

[0093] As shown in Figure 7(A), the fire hydrant device 10 is hung using a crane or the like and placed on the stand 30 installed above the guard passage, and the installation work is performed by aligning the housing side with the mounting hole 31 of the stand 30 shown in Figure 3 and attaching and fixing it using bolts and nuts.

[0094] 8(A), (B), and (C), when the installation work of the fire hydrant device 10 on the mount 30 is completed, the front mount cover 32 and the side mount cover 34 held on the housing side are released and rotate toward the mount 30, moving to a position where they cover and close the front and side of the mount 30. The front mount cover 32 and the side mount cover 34 rotated to a position where they cover and close the front and side of the mount 30 are held in the closed position by their own weight, but if a magnetic sheet 38 is also placed on the back surface of the front mount cover 32, they will also be attracted and held by the magnetic force of the magnetic sheet 38.

[0095] In this way, the fire hydrant device 10 is attached and fixed to the mount 30 installed on the road surface of the guard passage, and is provided with a front mount cover 32 and a pair of side mount covers 34 arranged to cover the front and both side surfaces of the mount 30, so that the angle material of the mount 30 arranged below the fire hydrant device 10 is covered and not exposed, thereby ensuring that the equipment is properly finished and does not detract from its appearance.

[0096] Furthermore, by covering the openings on the front and sides of the mount 30 with the front mount cover 32 and the side mount cover 34, it is possible to suppress and prevent the equipment such as pipes, wiring cables, valves, etc. placed or stored within the mount 30 from being soiled by dust in the tunnel space, thereby improving durability.

[0097] In addition, the front stand cover 32 and the side stand cover 34, which cover and hold the front and both side surfaces of the stand 30, can be rotated toward the housing using hinges 36, allowing the front and sides of the stand 30 to be easily opened, making it easy to perform work on the equipment and devices stored inside the stand 30 from outside.

[0098] As shown in Fig. 8(A), the front frame cover 32 has a length corresponding to the width in the left-right direction of the fire hydrant device 10, and is long, for example, about 2 meters. Therefore, as shown in Fig. 8(D), the front frame cover 32 divided into two parts 32 (32-1), 32 (32-2) may be pivotally supported on the lower ends of the decorative panels 13a, 13b by hinges 36 so as to be rotatable in the up-down direction.

[0099] In this way, by dividing the front stand cover into two, 32 (32-1) and 32 (32-2), the width of each cover is reduced, making opening and closing easier, and also making it possible to easily perform work inside the stand by opening the front stand covers 32 (32-1) and 32 (32-2) of the stand portion.

[0100] [c. Second embodiment of pedestal cover arrangement structure] The gantry cover arrangement structure of the second embodiment will be described in more detail with reference to Fig. 10, which shows the cover arrangement structure of the second embodiment in which the gantry cover is rotatably arranged on the upper side of the gantry.

[0101] 10, in this embodiment, a front cradle cover 32 is pivotally supported by a hinge 36 on the upper edge of the front surface of the cradle 30 so as to be freely rotatable in the vertical direction. Therefore, the front cradle cover 32 can be held in a position where it rotates toward the housing side to open the front surface of the cradle 30, as shown in the figure, or in a position where it rotates toward the cradle 30 side to cover and close the front surface, as shown by the arrow.

[0102] Similarly, side cradle covers 34 corresponding to both side surfaces of the cradle 30 are pivotally supported by hinges 36 on the upper edges of the side surfaces of the cradle 30 so as to be freely rotatable in the vertical direction. Therefore, as shown in the figure, the side cradle covers 34 are held in a position where they rotate toward the housing to open the side surfaces of the cradle 30, or as shown by the arrow, they are held in a position where they rotate toward the cradle 30 to cover and close the side surfaces.

[0103] The front base cover 32 and the side base cover 34, which have been rotated to a position where they cover the front and sides of the base 30 and are closed, are held in the closed position by their own weight, and are also attracted and held in the closed position by the magnetic force of the magnet sheets 38 arranged on the back surfaces of the front base cover 32 and the side base cover 34.

[0104] In this way, the fire hydrant device 10 is attached and fixed to the mount 30 installed on the road surface of the guard passage, and is provided with a front mount cover 32 and a pair of side mount covers 34 arranged to cover the front and both side surfaces of the mount 30, so that the angle material of the mount 30 arranged below the fire hydrant device 10 is covered and not exposed, so the equipment is properly finished and does not detract from its appearance.

[0105] Furthermore, by covering the openings on the front and sides of the mount 30 with the front mount cover 32 and the side mount cover 34, it is possible to suppress and prevent the equipment such as pipes, wiring cables, valves, etc. placed or stored within the mount 30 from being soiled by dust in the tunnel space, thereby improving durability.

[0106] In addition, the front stand cover 32 and the side stand cover 34, which cover and hold the front and both side surfaces of the stand 30, can be rotated toward the housing using hinges 36, allowing the front and sides of the stand 30 to be easily opened, making it easy to perform work on the equipment and devices stored inside the stand 30 from outside.

[0107] Furthermore, the front base cover 32 and the side base cover 34 are pivotally supported on the base 30 side so as to be freely rotatable, and therefore can be easily manufactured without affecting the structure of the housing of the fire hydrant device 10. The front base cover 32 may be divided into two in the left-right direction, as shown in Figure 8(D).

[0108] [d. Third embodiment of pedestal cover arrangement structure] The gantry cover arrangement structure of the third embodiment will be described in more detail with reference to Fig. 11, which shows the cover arrangement structure of the third embodiment in which the gantry cover is rotatably arranged on the lower side of the gantry.

[0109] 11, in this embodiment, a front frame cover 32 is pivotally supported by a hinge 36 on the lower edge of the front of the frame 30 so as to be freely rotatable in the vertical direction. Therefore, the front frame cover 32 can be held in a position where it rotates onto the surface of the guard passageway and opens the front of the frame 30, as shown in the figure, or it can be held in a position where it rotates toward the frame 30 and covers and closes the front, as shown by the arrow.

[0110] Similarly, the side mount covers 34 corresponding to both side surfaces of the mount 30 are pivotally supported by hinges 36 on the lower edges of the side surfaces of the mount 30 so as to be freely rotatable in the vertical direction. Therefore, the side mount covers 34 can be held in a position where they rotate onto the surface of the guard passageway to open the side surfaces of the mount 30, as shown in the figure, or in a position where they rotate toward the mount 30 to cover and close the side surfaces, as shown by the arrows.

[0111] The front frame cover 32 and the side frame cover 34, which have been rotated to a position covering the front and sides of the frame 30, are attracted and held in the closed position by the magnetic force of the magnetic sheet 38 arranged on the back side of the front frame cover 32 and the side frame cover 34.

[0112] In this way, the fire hydrant device 10 is attached and fixed to the mount 30 installed on the road surface of the guard passage, and is provided with a front mount cover 32 and a pair of side mount covers 34 arranged to cover the front and both side surfaces of the mount 30, so that the angle material of the mount 30 arranged below the fire hydrant device 10 is covered and not exposed, so the equipment is properly finished and does not detract from its appearance.

[0113] Furthermore, by covering the openings on the front and sides of the mount 30 with the front mount cover 32 and the side mount cover 34, it is possible to suppress and prevent the equipment such as pipes, wiring cables, valves, etc. placed or stored within the mount 30 from being soiled by dust in the tunnel space, thereby improving durability.

[0114] In addition, the front stand cover 32 and side stand cover 34, which cover and hold the front and both side surfaces of the stand 30, can be rotated toward the road surface side of the monitor's passage using hinges 36, allowing the front and sides of the stand 30 to be easily opened, making it easy to perform work on the equipment and devices stored inside the stand 30 from outside.

[0115] Furthermore, the front base cover 32 and the side base cover 34 are pivotally supported on the base 30 side so as to be freely rotatable, and therefore can be easily manufactured without affecting the structure of the housing of the fire hydrant device 10. The front base cover 32 may be divided into two in the left-right direction, as shown in Figure 8(D).

[0116] [e. Mounting cover arrangement structure of the fourth embodiment] The mount cover arrangement structure of the fourth embodiment will be described in more detail with reference to Fig. 12, which shows a fourth embodiment of the cover arrangement structure in which the mount cover is slidably arranged on the housing side of the fire hydrant device, Fig. 13, which partially shows a cover arrangement in which the front mount cover and the side mount cover are slidably supported on the bottom side of the side of the housing, Fig. 14, which shows the sliding structure of the front mount cover, and Fig. 15, which shows the sliding structure of the side mount cover.

[0117] Here, Fig. 12(A) shows the state in which the casing of the fire hydrant device is being attached and fixed to the casing, and Fig. 12(B) shows the state in which the casing of the fire hydrant device has been attached and fixed to the casing. Also, Fig. 14(A) shows the sliding structure of the front casing cover in plan view, and Figs. 14(B) and (C) show the front casing cover partially removed in plan and front views. Also, Fig. 15(A) shows the sliding structure of the side casing cover in plan view, and Figs. 15(B) and (C) show the side casing cover removed in plan and front views.

[0118] As shown in Figures 12(A) and 13, in this embodiment, a front frame cover 32 is supported on the lower front surfaces of the first housing 11a and second housing 11b of the fire hydrant device 10 so as to be freely slidable in the vertical direction, and a side frame cover 34 is supported on the lower right side surfaces of the housings so as to be freely slidable in the vertical direction.

[0119] The sliding structure of the front frame cover 32 is arbitrary, but as an example, as shown in Fig. 14(A), the right end of the decorative frame 13a arranged in front of the first housing 11a is used as a guide rail, and as shown in Figs. 14(B) and (C), a guide part 32c formed by bending the end of the right side of the front frame cover 32 into a U-shape is fitted into the right end face of the decorative frame 13a and supported so as to be slidable in the vertical direction. The sliding structure on the left end side of the second housing 11b is similar.

[0120] 15(A), taking the first housing 11a as an example, the right end surface of the decorative frame 13a arranged on the front of the first housing 11a is used as one guide rail, and a guide rail 42 is fixed in the vertical direction to the right end of the back surface of the first housing 11a, and as shown in Figures 15(B) and 15(C), guide portions 34a, 34b, which are formed by extending both ends of the upper side of the side frame cover 34 and bending them into a U shape, are fitted into the right end surface of the decorative frame 13a and the guide rail 42 at the right end of the back surface of the housing, and are supported so as to be slidable in the vertical direction. The sliding structure of the side frame cover 34 arranged on the lower left side of the second housing 11b is similar.

[0121] The front frame cover 32 and the side frame cover 34 are held in a slidable state toward the housing as shown in Fig. 12(A) until the fire hydrant device 10 is carried into the installation location in the tunnel. The front frame cover 32 and the side frame cover 34 that have been slid toward the housing can be held in place by any method, but they can be held in place using adhesive tape or appropriate stoppers, for example.

[0122] As shown in Figure 12(A), the fire hydrant device 10 is hung using a crane or the like and placed on the stand 30 installed above the guard passage, and the installation work is performed by aligning the housing side with the mounting hole 31 of the stand 30 shown in Figure 3 and attaching and fixing it using bolts and nuts.

[0123] Once the installation of the fire hydrant device 10 on the mount 30 is complete, as shown in Figure 12 (B), the front mount cover 32 and the side mount cover 34 held on the housing side are slid toward the mount 30 to move to a position where they cover and close the front and sides of the mount 30.

[0124] In this way, the fire hydrant device 10 is attached and fixed to the mount 30 installed on the road surface of the guard passage, and is provided with a front mount cover 32 and a pair of side mount covers 34 arranged to cover the front and both side surfaces of the mount 30, so that the angle material of the mount 30 arranged below the fire hydrant device 10 is covered and not exposed, so the equipment is properly finished and does not detract from its appearance.

[0125] Furthermore, by covering the openings on the front and sides of the mount 30 with the front mount cover 32 and the side mount cover 34, it is possible to suppress and prevent the equipment such as pipes, wiring cables, valves, etc. placed or stored within the mount 30 from being soiled by dust in the tunnel space, thereby improving durability.

[0126] In addition, the front stand cover 32 and the side stand cover 34, which cover and hold the front and both side surfaces of the stand 30, can be slid toward the housing to easily open the front and sides of the stand 30, making it easy to perform work on the equipment and devices stored inside the stand 30 from outside.

[0127] Furthermore, the front mount cover 32 and the side mount cover 34 slide up and down along the outer surfaces of the housing and mount 30, and therefore do not protrude into the guard passage and obstruct passage.

[0128] [f. Mounting cover arrangement structure of the fifth embodiment] The fifth embodiment of the mount cover arrangement structure will be described in more detail with reference to Fig. 16, which shows a fifth embodiment of the cover arrangement structure in which the mount cover is slidably arranged on the mount side of the fire hydrant device, Fig. 17, which shows a cover sliding structure in which the front mount cover and side mount cover are slidably supported on the mount side, Fig. 18, which shows a cover sliding structure on the right side of the housing, and Fig. 19, which shows a guide structure for the front mount cover and side mount cover provided on the mount.

[0129] Here, Figure 19(A) shows a plan view of the right side of the guide structure of the front stand cover and side stand cover provided on the stand, Figure 19(B) shows the guide structure from the front, and Figure 19(C) shows the guide structure from the side.

[0130] As shown in Figure 16, in this embodiment, a front frame cover 32 (32-1), 32 (32-2), which is divided into two parts in the left-right direction, is supported so as to be freely slidable in the vertical direction on the front of the frame 30 to which the housing of the fire hydrant device 10 is attached and fixed, and also, a side frame cover 34 is supported so as to be freely slidable in the vertical direction on both the left and right sides of the frame 30, as shown on the right side, for example.

[0131] The sliding structure of the front frame covers 32 (32-1) and 32 (32-2) relative to the front of the frame 30 is arbitrary, but as an example, as shown in Figures 17 and 18, a guide rail 44 bent in a U shape corresponding to the right front frame cover 32 (32-1) is fixed in the vertical direction at two locations, the right end and the center of the frame 30, with its opening side facing each other, and a guide rail 44 bent in a U shape corresponding to the left front frame cover 32 (32-2) is fixed in the vertical direction at two locations, the left end and the center of the frame 30, with its opening side facing each other.

[0132] The right and central guide rails 44 are arranged on the front of the stand 30, and both ends of the front stand cover 32 (32-1) are inserted from above into the guide rails 44, and the front stand cover 32 (32-1) is held in a position where it can slide freely to cover and close the opening on the right front side of the stand 30.

[0133] The left and central guide rails 44 arranged on the front of the stand 30 are also inserted from above at both ends of the front stand cover 32 (32-2), and are held in a slidable position to cover and close the opening on the left front of the stand 30.

[0134] The sliding structure of the side mount cover 34 on both side surfaces of the mount 30 is arbitrary, but as an example, as shown in Figures 17 and 18, a U-shaped bent guide rail 44 is fixed in the vertical direction with its opening sides facing each other at two locations, the front end and the rear end, on the right side of the mount 30. More specifically, as shown in Figure 19, at the front end of the right side of the mount 30, the guide rail 44 is fixed to an angle bar in the vertical direction, but at the rear end of the right side of the mount 30, an angle bar is arranged diagonally, and the guide rail 44 is also arranged diagonally along the angle bar.

[0135] Both ends of the side mount cover 34 are inserted from above into a pair of guide rails 44 arranged on the right side of the mount 30, and are held in a slidable position to cover and close the opening on the right side of the mount 30.

[0136] Once the installation of the fire hydrant device 10 onto the stand 30 above the guard passage is complete, the front stand cover 32 and the side stand cover 34 are inserted from above into a corresponding pair of guide rails 44 fixed to the stand 30 side, as shown in Figure 17, and moved to a position where they cover and close the front and sides of the stand 30.

[0137] In this way, the fire hydrant device 10 is attached and fixed to the mount 30 installed on the road surface of the guard passage, and is provided with front mount covers 32 (32-1), 32 (32-2) and a pair of side mount covers 34 arranged to cover the front and both side surfaces of the mount 30, so that the angle material of the mount 30 arranged below the fire hydrant device 10 is covered and not exposed, thereby ensuring that the equipment is properly finished and does not detract from its appearance.

[0138] In addition, the openings on the front and sides of the mount 30 are covered with the front mount covers 32 (32-1), 32 (32-2) and the side mount covers 34, which suppresses and prevents the pipes, wiring cables, valves, and other equipment placed or stored within the mount 30 from being soiled by dust in the tunnel space, thereby improving durability.

[0139] In addition, the front stand covers 32 (32-1), 32 (32-2) and the side stand covers 34, which are held over the front and both side surfaces of the stand 30, can slide along the guide rails 44 toward the housing, allowing the front and sides of the stand 30 to be easily opened, making it easy to perform work on the equipment and devices stored inside the stand 30 from outside.

[0140] Furthermore, the front frame covers 32 (32-1), 32 (32-2) and the side frame covers 34 slide up and down along the outer surfaces of the housing and the frame 30, and therefore do not protrude into the observer passage and obstruct passage. Note that, although the present embodiment uses the front frame covers 32 (32-1), 32 (32-2) that are divided into two, it is optional whether or not they are divided, and a single front frame cover may also be used.

[0141] [g. Modifications of the present invention] Modifications of the fire hydrant device according to the present invention will be described. In addition to the above-described embodiment, the fire hydrant device of the present invention includes the following modifications.
