[Operation of fire hydrant equipment]
(during normal monitoring)
During normal monitoring when a vehicle is traveling on the road of the tunnel 10 shown in FIG. 1, as shown in FIG. Since the supply of fire-fighting water from the mechanism is stopped, the hydraulic cylinder 60 of the elevating mechanism 46 positions the piston 61 at the lowest point, thereby causing the elevating mechanism 46 to bury the hose storage section 44 in the guard passage 14. Even if the fire hydrant is stored in the fire hydrant storage box 25 installed in advance, the fire hydrant entrance 42 is closed by the road surface board 50 on the upper surface of the housing 48, and the fire hydrant equipment 16 is installed in the observer passage 14, It does not impede or endanger the passage of persons passing through the guard passage 14.例文帳に追加

(in case of fire)
On the other hand, if a vehicle accident accompanied by a fire occurs in the tunnel 10, the user goes to the fire hydrant facility 16 near the place where the fire broke out, presses the transmitter 32 of the notification device panel 28, and the disaster prevention reception panel of the monitoring center displays the fire. A notification signal is transmitted, and an acknowledgment signal is received from the disaster prevention receiving panel to turn on the response lamp 34 and blink the red indicator light 30 to confirm completion of notification to the monitoring center side.

Subsequently, in order to carry out the fire extinguishing work, the raise switch 36a provided on the notification device panel 28 is pushed and turned on. When the lift switch 36 is turned on, fire-extinguishing water is sent from the control mechanism housing portion 45 to the hydraulic cylinder 60 of the lifting mechanism 46, and the fire-extinguishing water supplied into the cylinder lifts the piston 61, which is linked via the piston rod 63. The distance between the arm 46a and the link arm 46b is widened.

When the distance between the link arms 46a and 46b is increased, the angle of the link arms 46a and 46b widens around the fulcrum 47c, and the rollers 49a and 49b at the right end of the link arms 46a and 46b move leftward, resulting in the attachment. The base 43 is pushed upward, and the hose housing portion 44 attached to the mounting base 43 is pushed up.

As a result, the road surface plate 50 closing the fire hydrant entrance 42 of the fire hydrant storage box 25 is lifted, and the hose storage portion 44 stored inside slowly emerges from the road surface, rises to the exposed position shown in FIG. 4, and stops. , hold this exposed position.

At this time, as the hose housing portion 44 rises, the distance to the lower water supply pipe 58 connected by the connecting hose 62 becomes longer. Since the hose has a predetermined length that is longer than the distance to the floor surface, the connection state with some slack is established, and the connection between the water supply pipe 58 and the hose 54 is reliably maintained.

When the hose housing portion 44 is held in an exposed state above the guard passage 14 in this way, the user can simply and easily remove the hose by taking out the nozzle 56 through the front opening of the housing 48 from the road side. 54 can be drawn.
