Patent ID: 8113232

Claim:
A water flow control system for regulating water traveling through an existing water supply line, said water flow control system comprising: a housing adapted to be in fluid communication with the existing water supply line and an existing external power supply; a user interface communicatively coupled to said housing and the existing external power supply; and means for automatically preventing water from flowing downstream of said housing upon detection of at least one triggering event; wherein a first triggering event of said at least one triggering event is detected when the external power supply is interrupted; wherein a second triggering event of said at least one triggering event is programmable and selectively adjusted based upon a user input, said second triggering event being detected when a real-time water flow rate exceeds a maximum threshold water flow rate within the existing water supply line; wherein said automatic water flow preventing means comprises a controller situated within said housing and being communicatively coupled to said user interface; and a plurality of motion sensors situated within said housing and being communicatively coupled to said controller; wherein said user interface generates a calibration signal based upon receipt of a user input for adjusting said maximum threshold water flow rate associated with said second triggering event and thereby permitting the user to selectively modify said maximum threshold water flow rate as desired; wherein said automatic water flow preventing means further comprises a rotatable fan situated within said housing and adapted to be centrally aligned along a travel path of the water flowing within the existing water supply line, said fan including a plurality of rotatable blades equidistantly offset from a center of said fan; a plurality of tracks formed within said housing and oppositely spaced apart from a rotational path of said blades; a plurality of triggers slidably attached to said tracks respectively; and a plurality of resilient spring members having first and second ends anchored to said triggers and a corresponding end of said tracks respectively; wherein said fan is caused to rotate as water flows downstream of said housing along said travel path such that a rotational speed of said fan is commensurate with said real-time water flow rate; wherein said blades sequentially engage said triggers while traveling along said rotational path and thereby linearly urging said triggers along mutually exclusive longitudinal paths registered parallel to said travel path, said spring members being reciprocated between compressed and equilibrium positions such that said triggers are automatically returned to a resting position after being linearly urged to a displaced position.
