Arranged by drawing. The triangular mark 80 is black with no brightness, and has a strong contrast with the white back surface 76.

  Also, the downward triangle mark 80 is the same as the mark indicating the entrance of the fire brigade displayed on the glass surface of the building in the field of fire fighting equipment, and has high visibility in terms of shape. One of the most prominent identification marks.

  The triangular mark 80 is arranged such that the triangular mark 80 is hidden by the fire extinguisher 37 through the viewing window 35 in a state where two fire extinguishers 37 are accommodated as shown in FIG.

  By providing the positioning member 74 on the pedestal 72 against such an arrangement of the triangular mark 80, the arrangement position of the fire extinguisher 37 on the pedestal 72 is determined, and the positional relationship for hiding the triangular mark 80 arranged on the white back surface 76 is determined. It is set correctly.

  FIG. 5 is an explanatory view showing the fire extinguisher door closed in a state where the fire extinguisher is not accommodated. As shown in FIG. 5, when the fire extinguisher is not housed, a part of the triangular mark 80 arranged on the white back surface inside the housing can be visually recognized through the observation window 35 of the fire extinguisher door 32. At this time, since the triangular mark 80 is arranged by being drawn on a white background with high brightness, the triangular mark 80 has a strong contrast and can be seen as if the triangular mark 80 is raised in the viewing window 35. .

  Checking whether a fire extinguisher is stored in the fire hydrant device is performed while traveling in a tunnel with an inspection vehicle. Tunnels such as roads dedicated to automobiles are provided with the fire hydrant apparatus of the present embodiment shown in FIG. 1 at intervals of 50 m in the part of a supervisor passage provided along the side wall of the tunnel.

  Inspecting the fire extinguisher, an inspector gets on the inspection vehicle, holding the inspection light at the installation height of the tunnel fire hydrant device on the side wall of the tunnel, for example, the legal maximum speed in the tunnel is 80 km / h or less, for example Check while driving at 70 km / h.

  When passing through the tunnel hydrant device in which the fire extinguisher is housed, as shown in FIG. 2, it is determined by the fire extinguisher 37 that the triangle mark 80 is not visible and the fire extinguisher is housed normally. Can do.

  On the other hand, when a fire extinguisher is not stored in the fire hydrant device, irradiation light from the inspection light is radiated inside through the viewing window 35, and as shown in FIG. When the inspection vehicle passes the black triangular mark 80 in the white back surface illuminated by the light through 35, it immediately appears to float with a strong contrast, and it is immediately understood that the fire extinguisher is not housed.

  Here, in the inspection method according to the present embodiment, the height of the inspection light mounted on the inspection vehicle from the road surface is, for example, 1 corresponding to the installation height of the fire extinguisher storage portion 39 of the tunnel hydrant apparatus 10. The height is 2 meters.

  Further, when the inspection vehicle travels while irradiating light from the light toward the side wall of the tunnel, a range in which the triangular mark 80 can be visually recognized through the observation window 35 of the fire extinguisher door 32 of the tunnel hydrant apparatus 10 is shown in FIG. As shown in the plan view of FIG.

  In FIG. 6, assuming that the inspection vehicle is traveling in the direction of arrow A, the right end of the four triangular marks 80 arranged on the white back surface 78 starts to be visible as indicated by the line of sight a when the point P1 is reached. When the point P2 is reached, as shown by the line of sight b, the leftmost triangular mark 80 that has been visible until then disappears.

  In this way, the triangular mark 80 is arranged not only in front of the observation window 35 but also in the front position by arranging the triangular marks 80 on both sides of the white back surface 76 relative to the observation window 35. It can be seen while traveling from P1 to the rear position P2.

  Specifically, when the inspection vehicle travels at a position 3.5 meters away from the tunnel hydrant device, the triangle mark 80 is visible within a range of about 6 meters as the distance from the P1 point to the P2 point. .

  In addition, when checking the presence or absence of a fire hydrant device with the light irradiation light while traveling at an inspection vehicle speed of 70 km / h, the passing time of the fire hydrant device installed at intervals of 50 m is about 2.6 seconds. If the fire extinguisher is not continuously stored, if the presence or absence of the triangle mark 80 is confirmed from the inside of the inspection vehicle, the triangle mark 80 can be seen at intervals of about 2.6 seconds. The time during which the triangular mark 80 can be seen is about 0.3 seconds corresponding to a traveling range of 6 meters.

  In reality, there is no such thing as a fire extinguisher being stored in a row, and only a few of the tunnel hydrants have no fire extinguisher, or all of the tunnel hydrants are properly extinguished. As a result, the inspection vehicle is run while irradiating light in the tunnel, and if there is a fire hydrant device with a visible triangle mark 80, the fire hydrant device immediately extinguishes fire. It can be confirmed that the container is not stored.

  As an inspection vehicle, it can be confirmed sufficiently even at a speed of 70 km / h, but if this is 60 km / h, for example, the passing time of the installation interval of 50 m will be about 3 seconds. The presence or absence of a fire extinguisher can be reliably determined from the presence or absence of 80.

  Furthermore, even if the tunnel length is as long as several kilometers, it is possible to check for the presence of a fire extinguisher while traveling at a speed of, for example, 70 km. It is possible to check whether or not there is any.

  In the above embodiment, a plurality of black triangle marks are arranged side by side in a white background to check the presence or absence of a fire extinguisher, but the background color is an achromatic color with high brightness, That is, light gray may be used, and the triangle mark may be an achromatic color with low lightness, i.e., dark gray, as long as there is a sufficiently high contrast between them, and this relationship may be a combination with a chromatic color. good.

  In the above embodiment, a case where a plurality of downward triangular marks are arranged side by side as an example is taken as an example, but the shape of the marker may be an appropriate shape. Also, the height and arrangement interval of the markers can be appropriately set so as to be hidden or visible depending on the presence or absence of the fire extinguisher.

  Moreover, although said embodiment took the tunnel fire extinguisher apparatus integrated in the fire hydrant apparatus as an example, it can be applied as it is also to the tunnel fire extinguisher apparatus independently installed in a tunnel.

  That is, the tunnel fire hydrant device integrally provided with the fire extinguisher storage portion shown in FIG. 1 is installed in a tunnel with a large amount of traffic, but a tunnel with a small amount of traffic or a tunnel with a short distance even if the amount of traffic is large. A tunnel fire extinguisher device (fire extinguisher box) is installed, and in this case as well, the configuration for confirming the presence or absence of the fire extinguisher according to the present invention can be applied as it is.

The present invention includes appropriate modifications without impairing the object and advantages thereof, and is not limited by the numerical values shown in the above embodiments.
