Description

{Fire Hydrant Protection Device}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a technique used to protect a fire hydrant from a collision of a vehicle, and more particularly, to a fire hydrant that protects a fire hydrant by quickly opening a nozzle cap of a fire hydrant, And more particularly, to a fire hydrant protection device for a building, which can facilitate a fastening operation of a hose.

Generally, a fire hydrant is a fire hydrant for connecting a fire hose to a water supply pipe in a fire, and is distinguished by an indoor fire hydrant and an outdoor fire hydrant. Among these, in-ground outdoor fire hydrants are usually installed at the boundary of the roadway and the sidewalk, in order to make it easier to find the fire hydrant at night or when snow falls.

Since such outdoor fire hydrants are installed at the boundary between the roads and the sidewalks, there is a problem that the fire hydrants are conducted or damaged due to the collision of vehicles running around them. Therefore, a protection device for surrounding the fire hydrants is installed in order to protect them .

As shown in FIG. 1, the conventional fire hydrant protection device has a structure in which a pipe-shaped bollard 12 surrounding the hydrants 10 is installed on the foundation floor 14. As shown in FIG.

However, conventionally, before the fire hose (not shown) is coupled to the fire hydrant 10, the nozzle cap 16 installed in the fire hydrant 10 must be removed. However, the nozzle cap 16 The fastening tool is interfered with the bollard 12 when the wrench or pipe wrench is rotated in a narrow space, so that the separation operation of the nozzle cap 16 is delayed and it is difficult to evolve the fire quickly. .

In the conventional fire hydrant protection device, since the bollard 12 is fixed to the floor 14, the fire hose is obstructed by the bollard 12 when the fire hose is connected to the fire hydrant 10, So that it is difficult to tighten the fire hose.
