promptly the two-way rocker type switch plays to change manually, automatically interlocking in control circuit.At K 1-1When closed, electric current the elementary of transformer B of flowing through, its secondary induction output 12V alternating current is through D 1-D 4The bridge rectifier circuit rectification of forming, capacitor C 1Filtering, 7812 regulator block voltage stabilizings, output 12V stable DC.Resistance R 1, red light emitting diodes ZD 1Be serially connected between power supply and the ground, constitute power indicating circuit.At K 1-1Disconnect K 1-2When closed, the power supply of control circuit disconnects, and former manual operation system circuit is connected, the purpose of promptly realized manually, changeing automatically.Probe K 2In installation, an end by the signal wire connection control circuit+12V power supply, the other end and probe K 3Signal wire link to each other the current-limiting resistance R of this link serial connection control circuit 2To triode Q 1The b utmost point, capacitor C 2Be connected in parallel on Q 1B, the c utmost point, Q 1E utmost point ground connection, resistance R 3Be serially connected in Q 1The c utmost point and power supply between, R 3With Q 1The c polar contact meet triode Q 2The b utmost point, resistance R 4With red light emitting diodes ZD 2Behind the polyphone, with J 1Coil, J 1Protection diode D 5Be connected in parallel on power supply and Q 2The c utmost point between, Q 2E utmost point ground connection.Triode Q 3The b utmost point be connected to Q 2The c utmost point, Q 3The c utmost point connect power supply, the e utmost point connects probe K by signal wire when mounted 3The other end.J 1Normally closed contact 1 termination power.Above circuit constitutes the water source exploration circuit.Resistance R 5With capacitor C 3Be serially connected in J 1Between normally closed contact 2 ends and the ground, C 3Minus earth.R 5, C 3Contact connect NE555 2., 6. pin, resistance R 6Be connected on J 14. between the pin of normally closed contact 2 ends and NE555, the 1. pin ground connection of NE555,8. pin meets J 13. normally closed contact 2 ends are connected in series by resistance R between pin and the ground 7, yellow light-emitting diode ZD 3The delay indicating circuit that constitutes.This part constitutes delay circuit.Probe K 4In installation, an end is by signal wire connection control circuit J 12 ends, the other end and probe K 5Signal wire link to each other, this link is connected to control circuit, serial connection current-limiting resistance R 8To triode Q 4The b utmost point, resistance R 9Be connected to J 1Normally closed contact 2 ends and Q 4The c utmost point between, Q 4The e utmost point connect the 3. pin of NE555, C 4Be connected in parallel on Q 4B, the c utmost point.Triode Q 5The b utmost point meet R 9With Q 4The c polar contact, resistance R 10With green LED ZD 4Behind the polyphone, with relay J 2Coil, relay protection diode D 6Be connected in parallel on Q 5The c utmost point and J 1Between normally closed contact 2 ends, Q 5The e utmost point connect the 3. pin of NE555.Triode Q 6The b utmost point meet Q 5The c utmost point, Q 6The c utmost point meet J 1Normally closed contact 2 ends, the e utmost point meets K by signal wire in installation 5The other end.Controller in installation process, J 2The K of the two-way rocker type switch of the QA of normally opened contact and former manual operation system, TA, control circuit 1-2In parallel.This part constitutes the cistern water level circuit.When well has water, i.e. probe K 2, probe K 3All during adhesive, power supply is through R 2Saturated and conducting Q 1, Q 2Because of Q 1Conducting and end J 1Do not work, power supply is through J 1Normally closed contact is to cistern water level control circuit and delay circuit power supply, Q 2When ending, power supply is through J 1Coil, resistance R 4, ZD 2Conducting Q 3The well water level is reduced to K 2Disconnect K 3During adhesive, because Q 3Conducting, Q 1, Q 2, Q 3, J 1Duty remain unchanged, promptly power supply is through J 1Normally closed contact continues to cistern water level circuit and delay circuit power supply.Continue to drop to K at water level 3During disconnection, Q 3End Q 1Because of no bias current ends, Q 2By R 3Provide bias current and conducting, J 1Coil gets electric, J 1Normally closed contact disconnects, i.e. cistern water level circuit and delay circuit non-transformer, ZD 2The indication water source is anhydrous.Again rise to K at the water source 3During adhesive, because Q 3End Q 1, Q 2, J 1Duty remain unchanged, rise to K until water level 2During adhesive, Q 1Again conducting, Q 2End J 1Coil losing electricity, its normally closed contact closure, power supply is through J 1Normally closed contact is again to cistern water level circuit and delay circuit power supply.So repeatedly, it is anhydrous promptly to play the water source, protection automatically, and when water is arranged, the effect that protection automatically terminates.Delay circuit is delayed time and was controlled the power supply of cistern water level circuit in 5-10 minute in the biliquid level controller, and the one, when manual switch is automatic, play the delay protection effect.The 2nd, in tap water supply system, during pump working, the water source when cutting in and out, worked to prevent the water pump Fraquent start in 5 minutes.The 3rd, in pump working, civil power had a power failure repeatedly, when sending a telegram here, works to prevent the water pump Fraquent start in 5 minutes.The cistern water level circuit after delay circuit time-delay 5-10 minute, when water tank water is full, i.e. K 4, K 5The adhesive conducting, power supply is through current-limiting resistance R 8Conducting Q 4, because of Q 4Conducting, Q 5End J 2Do not work, its normally opened contact disconnects, and water pump is not worked, and simultaneously, power supply is through J 2Coil, R 10, ZD 4Conducting Q 6Drop to K at cistern water level 4During disconnection, power supply is through Q 6, K 5, R 8Conducting Q 4, i.e. Q 4, Q 5, J 2Duty remain unchanged, water pump keeps off position.Reduce to K at water level 5During disconnection, Q 6End Q 4End Q 5Conducting, J 2Work, water pump draws water, simultaneously ZD 4Indication is drawn water.When water level rises to K 5During adhesive, because of Q 6End Q 4End Q 5Conducting, circuit continue to keep the state that draws water, until K 4During adhesive, water pump quits work again.So change the control pump working according to cistern water level.Aforesaid full-automatic biliquid level controller is implemented control to water pump, thereby plays the effect of Automatic Control.
The power switch of the full-automatic biliquid level controller of the present invention connects into interlocking with former manual operation system, water source exploration circuit control delay circuit, and delay circuit time-delay cistern water level circuit just plays manually, changes automatically the effect of interlocking and delay protection; In pump working, meet in the civil power (or tap water) 5 minutes, have a power failure (or cutting off the water) repeatedly, during incoming call (or coming water), can prevent the water pump Fraquent start effectively; When the water source is anhydrous, protection automatically, when water was arranged, protection automatically terminated; Thereby water tower, water tank pumping system are played Automatic Control.This controller architecture is simple, and is multiple functional, and starting material are easily purchased, and manufacturing easy to implement has considerable DEVELOPMENT PROSPECT and using value, can produce very high economy and society benefit soon.
Below in conjunction with drawings and Examples the utility model is further specified
