Description

The present invention relates to a fire hydrant device that stores a fire hose, a fire extinguisher, etc. and is installed in a tunnel, and a fire extinguisher box that stores a fire extinguisher and is installed in a tunnel.

Conventionally, fire hydrant devices have been installed as tunnel emergency equipment in tunnels such as expressways and motorways. A fire hydrant device has a fire hydrant storage compartment in a housing equipped with a forward-tiling door (fire hydrant door), in which a fire hose with a nozzle attached to the tip and valves including a fire hydrant valve are stored, and a fire hydrant door is also provided. For example, two fire extinguishers are stored in the fire extinguisher storage section. Additionally, fire hydrant devices are generally installed by cutting out boxes in the tunnel wall and embedding them at intervals of, for example, 50 meters in the longitudinal direction of the tunnel.

By the way, in tunnels made using shield construction methods, etc., it is difficult to box out the tunnel wall and embed a fire hydrant device due to the cost and labor involved, due to the structure of the tunnel body. It is necessary to install the fire hydrant system in an exposed manner in the passageway.

In addition, in order to install the fire hydrant device on the tunnel wall without removing the box, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a pedestal installed on the tunnel wall. It is composed of a support portion, a posture holding member that maintains the posture of the fire hydrant device, etc. (Patent Document 2).

In addition, there are issues with wall-mounted fire hydrant devices, such as the labor and time it takes to install them on tunnel walls, so it is recommended that the fire hydrant device be exposed on a pedestal installed on the road surface of the lifeguard passageway, which is easy to install. It is being considered to have a so-called stationary structure in which the device is installed and fixed.

Japanese Patent Application Publication No. 2016-055073 Japanese Patent Application Publication No. 2020-078429

By the way, even if the fire hydrant device has a wall-mounted structure or a stationary structure, for example, two fire extinguishers are stored in the fire extinguisher storage section of the casing equipped with a fire extinguisher door, and when a fire breaks out, road users When using a fire extinguisher, the person must open the fire extinguisher door sideways (the door pivots on one side and rotate) and take out the fire extinguisher from the fire extinguisher storage compartment to extinguish the fire. If the fire extinguisher door remains open sideways after the fire extinguisher is removed, there is a problem in that it obstructs the passage of evacuees evacuating from the lifeguard passage.

This problem also applies to fire extinguisher boxes installed as emergency equipment in low-rank tunnels divided by traffic volume, tunnel length, etc.

DESCRIPTION OF EMBODIMENTS Below, embodiments of a fire hydrant device and a fire extinguisher box according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited to the following embodiments.

[Basic concept of embodiment]
First, the basic concept of the embodiment will be explained. Embodiments generally relate to a fire hydrant apparatus in which a fire hydrant device and a fire extinguisher are arranged within a housing.

Here, a "fire hydrant system" is a type of emergency equipment that is installed in tunnels of expressways and motorways that are targeted for fire extinguishing. Fire hydrant equipment, electrical equipment such as red indicator lights and transmitters, and fire extinguishers are arranged or housed in electrical doors, and the concept includes fire hydrant equipment equipped with fire hydrant devices.

Further, the fire hydrant device is installed in an exposed state at a predetermined height above the road surface of a lifeguard passage provided along the inner wall surface of a tunnel having a road. Here, the "predetermined height" is the height at which the fire hydrant device can be installed in close proximity to or in contact with the tunnel wall. It can be installed at a predetermined height by attaching and fixing the casing to the top, or by attaching and fixing the casing to the front part facing the road of a pedestal installed on the tunnel wall above the road surface of the lifeguard passage. It is something that

Furthermore, the term "frame" refers to a structure that supports something using pillars and beams, and includes concepts such as a support stand, a foundation, a base, a pedestal, and a base, although specific examples are not shown.

The fire hydrant device of this embodiment is characterized by being provided with a fire extinguisher drawer structure that allows a fire extinguisher placed horizontally in a fire extinguisher storage section in a housing to be taken out and taken out from the side of the housing, When a road user uses a fire extinguisher to extinguish a fire, it is possible to pull the extinguisher out toward the side of the hydrant device's housing without obstructing traffic through the lifeguard path. . Here, "laying the fire extinguisher horizontally" means placing the fire extinguisher in a horizontal position, which makes it possible to reduce the storage space for the fire extinguisher in the height direction within the housing.

The "fire extinguisher drawer structure" is for storing and pulling out two fire extinguishers individually corresponding to the upper and lower, in this embodiment, two side fire extinguisher doors, and its structure and shape are as follows. Although it is optional, for example, the fire extinguisher drawer structure may include an upper fire extinguisher drawer structure and a lower fire extinguisher drawer structure. The upper drawer structure includes an upper fire extinguisher storage section, an upper drawer main body, an upper side fire extinguisher door, and an upper drawer mechanism. The fire extinguisher storage structure on the lower side includes a lower fire extinguisher storage section, a lower drawer main body, a lower side fire extinguisher door, and a lower drawer mechanism.

Here, taking the fire extinguisher drawer structure on the upper side as an example, the "upper fire extinguisher storage section" refers to the fire extinguisher storage section in the housing corresponding to the upper drawer opening that is divided into upper and lower parts. This is a storage section formed on the upper side. Moreover, the "upper drawer main body" is located at the bottom side of the upper drawer opening and is installed in the upper fire extinguisher storage part so that it can be freely taken in and taken out.

(Wall-mounted fire hydrant device)
The above embodiment takes as an example a fire hydrant device with a stationary structure in which the casing is attached and fixed to the top of a pedestal that is installed on the road surface of the lifeguard passageway in close proximity to or in contact with the tunnel wall side. This is not limited to this, and similarly, fire hydrant devices with a wall-mounted structure in which the casing is attached and fixed to the front part facing the road of a pedestal installed on the tunnel wall above the road surface of the lifeguard passageway are also covered. A side door is provided on the casing, and by opening the side door, it is possible to work on the inside of the casing from outside the side.

(When the tunnel wall has a cross section other than circular)
The tunnel cross-sectional shape in the above embodiment is circular, but if the tunnel cross-section is other than circular, for example, tricentric, the horizontal line at the widest horizontal width of the tunnel cross-sectional shape is The present invention can be applied by using the tunnel center line SL1 in the description.

(Structure of fire hydrant device compatible with thinning)
In the fire hydrant device in the above embodiment, in response to the thinning of the fire hydrant device, the width of the first casing and the second casing are widened to secure the internal volume reduced by the thinning. The vertical widths of the first casing and the second casing may be widened to secure the internal volume reduced due to thinning.

(Diagonally downward drawer mechanism)
The drawer mechanism of the above embodiment may support the drawer main body so as to be movable in a direction at a predetermined angle that is inclined diagonally downward with respect to the horizontal direction of the drawer. Although the diagonally downward angle is arbitrary, for example, by supporting the drawer main body so that it can move freely in the direction of the diagonally downward inclination angle of about 2 to 3 degrees with respect to the horizontal direction, road users can use the door handle to When the fire extinguisher door is unlocked, the fire extinguisher can be pulled out with a light force and exposed to the removal position, and the fire extinguisher can also be moved in an inclined direction by the weight of the drawer body placed vertically. Even if a force is applied and the door handle is released, the fire extinguisher can be moved to the removal position. Here, "horizontal" is not limited to being parallel to the level indicated by the spirit level, that is, perpendicular to the vertical, but is also approximately parallel to the tunnel road surface, or at least corresponds to the installation location if the road surface has a varying slope. This includes being approximately parallel to the road surface, and furthermore, when the width direction of the casing is installed approximately parallel to the road surface, it is approximately parallel to the lateral direction (left-right direction, width direction) of the casing in the installed state, or This is a concept that includes being substantially perpendicular to the vertical direction (vertical direction, height direction). Moreover, a "horizontal line" is a line substantially parallel to the "horizontal" direction.

(Drawer mechanism)
The pull-out mechanism of the fire extinguisher pull-out structure in the above embodiment is a pull-out mechanism using two guide rails in which the pull-out guide rail of the drawer body is slidably fitted into the guide rail of the fixed side housing. However, a drawer mechanism using three guide rails in which an intermediate guide rail is arranged between the housing guide rail and the drawer guide rail may also be used.
