Embodiment 1
[0036] Embodiment one, with reference to figure 2As shown, when there is no fire, the second plate 14 stretches into the first groove 16 on the valve stem 6, and the first rack 19 also stretches into the corresponding first limiting hole 20, so that the Personnel cannot turn the handwheel on the fire hydrant 4 so that the fire hydrant 4 cannot be opened, and the pull pin 17 abuts against the first protrusion. The purpose of this setting is to allow the second plate 14 to pass through Pulling the pin 17 and the first protrusion drives the first rack 19 to move, so that we don't need to pull the second plate 14 and the first rack 19 at the same time, which reduces the workload. The second plate 14 pulls out the first groove 16 on the valve stem 6 and manually pulls the first rack 19 out of the first limit hole 20, which will waste firefighters' firefighting time, so we set the following structure Before the fire-fighting interface 7 on the fire hydrant 4 is connected to the fi...
Embodiment 2
[0041] Embodiment two, on the basis of embodiment one, refer to Figure 6 and t Figure 7 As shown, the existing fire-fighting interface 7 is generally exposed in the fire hydrant box 1, and foreign matter can enter the interior of the fire hydrant 4 through the fire-fighting interface 7. When the valve stem 6 cannot be opened to waste rescue time; in order to prevent foreign matter from entering the fire hydrant 4, we have set up the following structure;
[0042] We fixedly install the second bracket on the inner bottom wall of the fire hydrant box 1, we vertically slide and install the holding plate between the second and we place the fire hose 2 and the fire water nozzle 3 on the holding plate, usually When there is no fire, the fire hose 2 and the fire nozzle 3 are placed on the storage board. Once a fire occurs, the firefighters can remove the fire hose 2 and the fire nozzle 3 and connect them to the fire interface 7 to fight the fire. We are provided with trigger sprin...
Embodiment 3
[0045] Embodiment three, on the basis of embodiment two, refer to Figure 6 and Figure 7 As shown, the storage plate moves vertically upwards to drive the second rack 36 fixedly installed on it to move, and the second rack 36 moves to drive the third gear 37, which is installed in engagement with it and installed on the fire hydrant box 1, to rotate. The third gear 37 rotates through the first bevel gear set and the first belt transmission to drive the first rotating plate 29 to rotate, and the first rotating plate 29 rotates to drive the first round sleeve 34 to separate from the fire-fighting interface, and the firefighters connect the fire-fighting hose 2 to the Fire fighting on the fire interface 7;
[0046] After the firefighters extinguished the fire, the firefighters took off the fire hose 2, put the fire hose 2 and the fire hose 3 on the holding board, and the holding board descended under the action of the gravity of the fire water and fire hose 3, The storage plat...
