发明名称 Keyless fire hydrant protection system
摘要 The protection system protects a fire hydrant. The protection system includes a nozzle, a protection device, and a bracket assembly. The nozzle defines a bore, is in fluid communication with an interior of the fire hydrant, and is adaptable to receive a fire hose. The protection device is carried by the bore of the nozzle for prohibiting access into the interior of the fire hydrant from the exterior. The protection device includes a first position for preventing access into the fire hydrant from the exterior, and a second position wherein water can flow from inside the fire hydrant externally via the nozzle. The bracket assembly is coupled to the protection device for rotating the protection device and carried by the nozzle, wherein the bracket assembly has sufficient rotational travel for enabling the protection device to move from the first position to the second position, depending on the water pressure.
