(Mounting method)
Next, in the fire hydrant device 100 configured as described above, an attachment method for attaching the fire detector 2 to the fire hydrant device 100 will be described. 18 to 20 are side views for explaining how to attach the fire detector.

The method of attaching the fire detector 2 is arbitrary, but in the present embodiment, generally, after the fire detector 2 is attached to the first holding plate 4 and the second holding plate 5, the fire detection is performed. The case where the vessel 2 is attached to the front panel 3 will be described as an example.

First, the fire detector 2 of FIGS. 8 and 9 is positioned with respect to the first holding plate 4 of FIGS. 13 to 15 (hereinafter, also referred to as “first step”). In the "first step", for example, by arranging the first portion 21 of the fire detector 2 in the opening 41 on the first holding plate side from the back surface side (-X direction) of the first holding plate 4, FIG. As shown in, the fire detector 2 is positioned with respect to the first holding plate 4. In this case, the first portion 21 of the fire detector 2 is fitted into the opening 41 on the first holding plate side.

Next, the fire detector 2 of FIG. 18 is fixed to the first holding plate 4 (hereinafter, also referred to as “second step”). In the "second step", for example, the second holding plate 5 of FIGS. 16 and 17 is provided on the back surface portion 221 of the fire detector 2, and then the holding bolt 62 is secondly held as shown in FIG. By screwing into both the second holding plate side bolt hole 51 of the plate 5 and the first holding plate side nut 42 of the first holding plate 4, the first holding plate 4 and the second holding plate 4 and the second holding plate are screwed through the holding bolt 62. 5 are connected. In this case, the second portion 22 of the fire detector 2 is sandwiched between the first holding plate 4 and the second holding plate 5, so that the fire detector 2 presses against the first holding plate 4. Will be fixed.

Next, the fire detector 2 of FIG. 19 is exposed via the front panel 3 of FIGS. 10 to 12 (hereinafter, also referred to as “third step”). In the "third step", for example, first, as shown in FIG. 19, the first holding plate 4 to which the fire detector 2 is fixed is transferred from the back side (-X direction) of the front panel 3 to the front panel 3. Make a contact. In this case, the first portion 21 of the fire detector 2 is arranged in the panel side opening 32 of the front panel 3, and the panel side nut 33 of the front panel 3 is a long hole of the first holding plate 4. It is arranged at 43. Then, the first portion 21 of the fire detector 2 projects from the front panel 3 to the front side (+ Z direction) via the first holding plate side opening 41 and the panel side opening 32, and is on the monitoring area side in the tunnel. Will be exposed to.

Next, the mounting angle of the fire detector 2 in FIG. 19 is adjusted (hereinafter, also referred to as “fourth step”). The step here corresponds to, for example, "a step of adjusting the mounting angle of the fire detector with respect to the mounting target so that the fire detector can be mounted". 21 to 26 are views for explaining the adjustment of the mounting angle of the fire detector. 21 and 24 are front views of the front panel 3 and the fire detector 2, and FIGS. 22 and 25 are rear views of the front panel 3 and the fire detector 2 and the like. 23 and 26 are front views showing the installation state of the fire hydrant device 100.

In the "fourth step", for example, the rotation angle of the fire detector 2 is adjusted so that the viewing space 200 of the fire detector 2 described with reference to FIG. 7 is appropriately set according to the slope of the road surface 91. Then, the mounting angle of the fire detector 2 is adjusted.

Specifically, it is optional, but for example, as shown in FIGS. 21 and 22, the fire detector is so that the reference line 2A on the fire detector side in FIG. 21 is parallel to the horizontal direction (Y-axis direction). When 2 is attached, as shown in FIG. 23, a part of the lower surface boundary 201 of the viewing space 200 (in the example of FIG. 23, the other side (−Y direction) end) is above the road surface 91 ( Since it is provided in the + Z direction), the viewing space 200 is not properly set. In this case, the fire detector 2 is rotated together with the first holding plate 4 by an arbitrary angle in the direction indicated by the arrow A1 in FIGS. 21 and 22 around the rotation shaft 300 shown in FIGS. 10 to 12. As shown in FIGS. 24 and 25, the fire detector side reference line 2A in FIG. 24 is tilted by an arbitrary angle with respect to the horizontal direction (Y-axis direction). In this case, as shown in FIG. 26, since the entire lower surface boundary 201 of the visual field space 200 coincides with the road surface 91, the visual field space 200 is appropriately set.

The method of rotating the fire detector 2 and the first holding plate 4 in the direction indicated by the arrow A1 in FIGS. 21 and 22 is arbitrary. For example, the lower surface 951 in the accommodating portion 95 in FIG. 2 is horizontal. Since it is parallel to the direction (Y-axis direction) and the fire extinguisher device 100 is installed horizontally, the upper and lower sides of the rectangle of the front panel 3 of FIGS. 22 and 25 are horizontal (Y-axis direction). You may rotate it as follows, paying attention to the fact that it is parallel to the above. For example, it may be rotated by an arbitrary angle while grasping the angle to be rotated by paying attention to the relative positional relationship between the plurality of scale lines of the scale 34 in FIG. 22 and the triangular arrow 44.

Next, the fire detector 2 of FIG. 19 is fixed to the front panel 3 (hereinafter, also referred to as “fifth step”). In the "fifth step", for example, the fixing bolt 61 (FIG. 6) is screwed into the panel side nut 33 arranged in the elongated hole 43 shown in FIG. 20, and the first holding plate 4 is brought to the front surface. By pressing and fixing to the panel 3, the fire detector 2 fixed to the first holding plate 4 is fixed to the front panel 3. In this way, as shown in FIG. 26, the fire detector 2 is attached to the fire hydrant device 100. This completes the mounting method.

The sex can be improved. Further, for example, it is possible to prevent the fire detector 2 from directly contacting and rubbing against the front panel 3.

Further, by making the fire detector 2 rotatable in a state where the panel side nut 33 which is a guide portion is arranged in the elongated hole 43, for example, the rotation of the fire detector 2 can be rotated by the panel side nut which is a guide portion. Since it can be guided by the 33 and the elongated hole 43, the adjustment accuracy of the mounting angle of the fire detector 2 can be improved.

Further, since the guide portion is the panel side nut 33 and the fixing means is the fixing bolt 61, for example, at least a plurality of functions (for example, a function of guiding the rotation of the fire detector 2 and a fire detector) are provided to the guide portion. Since it is possible to have a function of fixing 2), it is possible to reduce the number of parts for realizing each function.

Further, the first holding plate side opening 41 has a non-circular shape (for example, an elliptical shape) corresponding to the outer shape of the first portion 21 of the fire detector 2, and the panel side opening 32 has the first holding plate side opening 41. By having a circular shape having a major axis 411 of a non-circular shape (for example, an elliptical shape) as a diameter, for example, the fire detector 2 can be reliably rotated, and the first portion 21 of the fire detector 2 can be formed. The fire detector 2 can be appropriately held in a state of being projected toward the monitoring area.

Further, by providing a second holding plate 5 for holding the fire detector 2 by sandwiching a part of the fire detector 2 with the first holding plate 4, for example, the fire detector 2 can be held more firmly. can do.
