Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the water pipe burst and water leakage alarm device comprises a micro water flow generator 1, an electromagnetic valve 2, a 12V voltage stabilizer 3, an overvoltage judgment unit 4, a duration judgment unit 5, a 12V dc power supply unit 6, an audible and visual alarm control unit 7, a relay 8, a wireless alarm signal sending unit 9, and an 220/24V ac isolation step-down transformer 10.
The miniature water flow generator 1 is arranged on a water pipe behind the household water meter, and the electromagnetic valve 2 is arranged on the water pipe behind the miniature water flow generator.
The input end of the 12V voltage stabilizer 3, the input end of the overvoltage judging unit 4 and the input end of the duration judging unit 5 are connected in parallel with the output end of the micro water flow generator.
The positive output end of the 12V voltage stabilizer 3 is connected with the positive electrode of the first rectifying diode D1, and the negative output end is used as the power supply negative electrode B; the input end of the 12V direct current power supply unit 6 is connected with commercial power, and the negative output end is used as a power supply negative electrode B; the cathode of the first rectifying diode D1 is connected to the cathode of the second rectifying diode D2 as the power supply anode A. The power supply inputs of the overvoltage judging unit 4, the duration judging unit 5 and the audible and visual alarm control unit 7 are respectively connected with a power supply anode A and a power supply cathode B.
The signal output end of the overvoltage judging unit 4 is respectively connected with one signal input end of the acousto-optic alarm control unit 7 and one signal input end of the relay 8, the signal output end of the duration judging unit 5 is respectively connected with the other signal input end of the acousto-optic alarm control unit 7 and the other signal input end of the relay 8, and the signal output end of the acousto-optic alarm control unit 7 is connected with the wireless alarm signal sending unit 9.
The power input end of the relay 8 is connected with the commercial power, the power output end of the relay 8 is connected with the input end of the 220/24V alternating current isolation step-down transformer 10, and the output end of the 220/24V alternating current isolation step-down transformer 10 is connected with the input end of the electromagnetic valve 2 to control the opening and closing of the electromagnetic valve 2. The 220/24V AC isolation step-down transformer 10 adopts a step-down DC blocking transformer.
The alarm device adopts double power supplies to work: under normal conditions, the electricity generated by the micro water flow generator 1 is converted into stable 12V direct current by the 12V voltage stabilizer 3, then converted into 12V direct current by the first diode D1 and the commercial power through the 12V direct current power supply unit 6, and then supplied to the overvoltage judgment unit 4, the duration judgment unit 5 and the audible and visual alarm control unit 7 through the second diode D2. When no commercial power is available, if a water pipe bursts or a large flow rate leaks, the electricity generated by the micro water flow generator 1 is changed into stable 12V direct current by the 12V voltage stabilizer 3, and then the stable 12V direct current passes through the first diode D1 to provide 12V power for the overvoltage judging unit 4, the duration judging unit 5 and the audible and visual alarm control unit 7, and the second diode D2 is cut off. The output of the relay 8 controls the on-off of the 220/24V AC isolation step-down transformer 9, and the electromagnetic valve 2 adopts a low-voltage normally-open type electromagnetic valve which is supplied with power by AC 24V isolated by the transformer.
The miniature water flow generator 1, the electromagnetic valve 2, the 12V voltage stabilizer 3, the overvoltage judging unit 4, the duration judging unit 5, the 12V direct-current power supply unit 6, the acousto-optic alarm control unit 7, the relay 8, the 220/24V alternating-current isolation step-down transformer 9 and the wireless alarm signal sending unit 10 in the water pipe bursting and water leakage alarm device are mature existing products, can be purchased and can be used by adjusting parameters as required. The water pipe burst and water leakage alarm device has the following specific working process:
when a water pipe burst condition occurs: when the water pipe bursts, the water flow is increased, the output voltage of the miniature water flow generator 1 is large, the amplitude of an input signal received by the overvoltage judging unit 4 is larger than an alarm set value, the overvoltage judging unit 4 sends a signal to trigger the acousto-optic alarm control unit 7 and the relay 8 to work, and meanwhile, the acousto-optic alarm control unit 7 sends a water pipe burst alarm signal to an owner or a management department through the wireless alarm signal sending unit 10. Meanwhile, the mains supply is subjected to voltage reduction through an 220/24V alternating current isolation step-down transformer 9 by a relay 8 and then is supplied to the electromagnetic valve 2 for power supply, the electromagnetic valve 2 works, and a water pipe passage is closed.
When a small-flow water leakage condition occurs: when the water pipe has small flow leakage and the output voltage of the micro water flow generator 1 is too low to trigger the overvoltage judging unit 4, the duration judging unit 5 judges whether a water leakage event occurs according to the duration of the output signal of the micro water flow generator 1, namely the duration of water flow. When the water flow duration is longer than the set value, the water pipe is judged to be leaked, the miniature water flow generator 1 sends a signal to trigger the acousto-optic alarm control unit 7 and the relay 8 to work, and meanwhile, the acousto-optic alarm control unit 7 sends a water pipe leakage warning signal to an owner or a management department through the wireless alarm signal sending unit 10. Meanwhile, the mains supply is subjected to voltage reduction through an 220/24V alternating current isolation step-down transformer 9 by a relay 8 and then is supplied to the electromagnetic valve 2 for power supply, the electromagnetic valve 2 works, and a water pipe passage is closed.
When a power failure condition occurs: when power is off, once a water pipe bursts or large-flow leakage occurs, electricity generated by the miniature water flow generator 1 is supplied to the overvoltage judging unit 4, the duration judging unit 5 and the audible and visual alarm control unit 7 through the 12V voltage stabilizer 3 and the first diode D1, the alarm function is normal, but the electromagnetic valve cannot be turned off.
