Background technology
When different, when water level is below or above warning line, all can bring certain harm, need water level alarm to detect in real time water level for this reason.Water level alarm is the warning being carried out water level by the method for mechanical type or magnetic induction, can be reported to the police control starting or stoping of the equipment such as water pump simultaneously by audible-visual annunciator or magnetic.Water level alarm is reported to the police by electronic level switch or float switch, the principle of electronic level switch is detected water level by electronic probe, by water level detecting special chip, the signal detected is processed again, when fluid to be measured arrives operating point, export high or low level signal, then hydrous water level controller, output relay switching signal, or directly power supply is to alarm, thus realize the warning function to liquid level; The principle of float switch is by the fluctuate magnetic reed switch that attract pole inner band have tongue tube of inside with ring-shaped magnet ball float water level at any time, sends switch alarm signal.
Current water level alarm structure relative complex, the components and parts related to are more, and not only cost is higher, and power consumption increases, and is unfavorable for long use, change battery continually and also make operation pretty troublesome.
Utility model content
The purpose of this utility model is to provide a kind of low-power consumption level alarm for water, solves current low water alarm power consumption comparatively large, is unfavorable for long use, changes battery continually and also makes to operate pretty troublesome problem.
The utility model for achieving the above object, realizes by the following technical solutions:
A kind of low-power consumption level alarm for water, comprise triode Q1, triode Q2, triode Q3, resistance R1, resistance R2, resistance R3, electric capacity C, loudspeaker Y, power supply and two probe S, the collector of described triode Q1 connects the positive pole of power supply, the emitter of triode Q1 connects the collector of triode Q2, the emitter of described triode Q2 connects the base stage of triode Q3, the grounded emitter of triode Q3, described in one of them, probe is connected to the base stage of triode Q1, the positive pole of power supply is connect after another probe S series resistor R1, the emitter of the one termination triode Q1 of described resistance R2, the base stage of another terminating diode Q2 of resistance R2, the base stage of the one terminating diode Q2 of described electric capacity C, the other end ground connection of electric capacity C, the base stage of the one termination triode Q3 of described resistance R3, the other end ground connection of resistance R3, the one termination positive source of described loudspeaker Y, the collector of another termination triode Q3.
In this programme, when the S that pops one's head in does not contact water, two probe S disconnect, and the base stage of triode Q1 is in open-circuit condition, and triode ends, thus make triode Q2, triode Q3 ends equally, now loudspeaker Y does not work, after water level rises to and contacts with the S that pops one's head in, the base stage of triode Q1 is connected, and conducting is realized under the effect of power supply, triode Q2, the conducting successively of triode Q3 correspondence, D resistance R2 and electric capacity C produces vibration signal, and export loudspeaker Y to by triode Q3, thus make loudspeaker Y realize sounding alarm, the alerting signal frequency of loudspeaker Y depends on the value of electric capacity C and resistance R2, in whole circuit, required electric current is the leakage current of transistor, therefore, the electric current that this circuit consumes is very little, general battery can realize long use, battery need not be changed continually.In addition, by the change to probe S, water level alarm can be used as rainfall alarm or short-circuit alarming device.
Further, preferably, the model of described triode Q1 is BC107.
Further, preferably, the model of described triode Q2 is 2SA1012Y.
Further, preferably, the model of described triode Q3 is BFY51.
Further, preferably, the resistance of described resistance R1 is 100K Ω, and the resistance of resistance R3 is 120 Ω.
Further, preferably, the resistance of described resistance R2 is 200K Ω, and the capacitance of electric capacity C is 0.01 μ F.
Further, preferably, the resistance of described loudspeaker Y is 16 ~ 90 Ω.
The utility model compared with prior art, have the following advantages and beneficial effect: after water level rises to and contacts with the S that pops one's head in, the base stage of triode Q1 is connected, and conducting is realized under the effect of power supply, triode Q2, the conducting successively of triode Q3 correspondence, D resistance R2 and electric capacity C produces vibration signal, and export loudspeaker Y to by triode Q3, thus make loudspeaker Y realize sounding alarm, the alerting signal frequency of loudspeaker Y depends on the value of electric capacity C and resistance R2, in whole circuit, required electric current is the leakage current of transistor, therefore, the electric current that this circuit consumes is very little, general battery can realize long use, battery need not be changed continually.
