PT107726A - WATER LEAK DETECTION SYSTEM WITH AUTOMATIC CUTTING - Google Patents

Abstract

THE SYSTEM THAT IS PRESENT DETECTS WATER LEAKS IN PIPELINE AND AUTOMATICALLY CUT THEIR SUPPLY IN CASE OF EXISTING FLOW, FOR A TIME PERIOD BEYOND THE PRESET. THE SYSTEM IS CONSISTENT BY A WATER INLET PIPE (1) THAT CONNECTS DIRECTLY TO AN ELECTROVALVE (2). FOR YOUR TIME, CONNECT TO THE FLOW SENSOR (3) THAT FINALLY CONNECTS TO THE WATER OUTLET (4) FOR THE REMAINING PIPELINE. THE MICROCONTROLLER (5) COLLECTS FLOW SENSOR DATA (3). IN ACCORDANCE WITH THE TIME DEFINED IN THE SELECTOR (9), THE MICROCONTROLLER ACTIONS THE ELECTROVALVE (2) TO MAKE THE WATER CUT. WHEN THE WATER IS CUT OUT The LED (7) is ON. THE KNOB (8) PERMITS MANUAL RESETTING THE WATER PASS, BY TURNING OFF THE SOLENOID VALVE (2). EVERY SYSTEM IS POWERED BY THE ENERGY MODULE (6).

TECHNICAL FIELD OF THE INVENTION The system is in the field of electronics, sensors and actuators, applied in the detection and prevention of water leakage.

Water leakage from domestic, industrial or other piping is a reality that is sometimes overlooked because of its insignificance. The system shown has a flow sensor (3) to sense the passage of water in the pipe, and the solenoid valve (2) to make the water pass through. The microcontroller 5 activates the cutout 2 when there is water passage in the flow sensor 3 and is maintained for a period of time greater than that defined in the time selector 9 which may be for example 1 minute , 5 minutes, 15 minutes or 1 hour. If the water flow is zero before reaching the time limit, the time count is reset.

When the microcontroller (5) cuts off the water by activating the solenoid valve (2), a light signal is activated via the LED (7). To re-establish the passage of water in the pipes, press the button (8) by hand.

State of the art • The system does not use wired or wireless communications. (US 20 12/0026004 Ai) • The system detects no power consumption. (US 20 12/0026004 Ai) • The displayed system will cut the water automatically and not by the user's order. (US 20 12/0026004 Ai) • The system shown does not calculate the difference in flow to determine a water leak. It only counts time. (CN201749334U, US 20 12/0026004 Ai) • The system uses only one flow sensor. (CN2 017 4 9334U) • The microcontroller is located near the electrovalve and the flow sensor and not remotely. (US 2008/0295895 Ai) • The system does not store data or flow patterns to determine water leaks. (US 2008/0295895 A1)

SUMMARY OF THE INVENTION The present system detects leakage of water in pipes and automatically cuts off its supply, if there is a flow, for a longer period of time than the predefined one. The system consists of a water inlet pipe (1) which connects directly to an electrovalve (2). In turn, it connects to the flow sensor (3) which finally connects to the water outlet pipe (4) for the remaining pipe. The microcontroller (5) collects data from the flow sensor (3). According to the time set in the selector (9), the microcontroller switches on the solenoid valve (2) to cut off water. When the water is cut off, the LED (7) lights up. The button (8) allows you to manually reset the water flow by deactivating the solenoid valve (2). The entire system is powered by the power module (6).

Detailed Description The solenoid valve (2) is an electromagnetic device that at rest allows the passage of water. As soon as it is supplied with energy, it closes the water. The flow sensor (3) or flowmeter is an electrical device that generates electrical impulses only when there is water flow. The time selector (9) consists of a set of buttons connected to digital ports of the microcontroller (5). Together, they provide an electrical combination that allows the microcontroller (5) to recognize the maximum permissible water passage time. The microcontroller (5) collects data from the flow sensor and time selector to then time the water passage and make the cut. The light signal (7) consists of an LED that lights up when the water is cut off. The pushbutton (8) when pressed activates a digital port of the microcontroller (5) so that the water passage is restored by opening the solenoid valve (2). The power module 6 consists of supplying the circuit with a low voltage DC current, by means of a battery or power transformer connected to the distribution network.
