Description

A smart fire hydrant

technical field

The invention relates to the technical field of fire fighting equipment, in particular to the technical field of an intelligent fire hydrant.

Background technique

Fire hydrant is used for municipal water supply and fire water intake. It is a fixed fire fighting facility. It is divided into indoor fire hydrants and outdoor fire hydrants. Most of them are columnar water supply pipe sections installed on the ground. The wall-mounted water outlet mostly adopts a mechanical water valve. When in use, the water valve is opened or closed with a special tool to complete the water intake and closing. Fire hydrant sets are generally composed of fire boxes, fire hoses, water guns, connectors, bolts and clips. Fire hydrant is one of the important fire facilities and the foundation of fire safety.
