A fire hydrant什麼意思

"A fire hydrant" is a device used by firefighters to connect hoses to a water supply in order to provide water for fighting fires. It is typically a red, upright, cylindrical object with a valve that can be opened to release water, often with a network of underground pipes connecting it to a water main. Fire hydrants are usually found on streets or in public areas and are an important part of a community's fire protection system.
