Warning device for determining water flow status

A warning device for determining water flow status, comprising:

• a main body, including a flow channel formed in the main body and penetrating through both ends of the main body to form a water outlet end and a water inlet end, and an opening formed on a side of the main body, and an intersection of the flow channel and the opening defining and forming a working chamber;
• a power generating device, fixed into the working chamber, and having pivoting turbine blade, and including a light emitting element, so that a water flow can push the turbine blade to generate electric power to be supplied to the light emitting element to emit light;
• a flow diverting element, installed on the power generating device, and including a slot compartment formed by a shaft cover and a sidewall, and the turbine blade being covered into the slot compartment with the flow diverting element, wherein the flow diverting element includes a plurality of flow diverting holes provided for flowing water from the flow diverting holes into the slot compartment to push and move the turbine blade;
• and
• a cover, being translucent, and installed and sealed onto the opening of the main body.
