Brief description of the drawings
Fig. 1 is invention overall structure and circuit theory diagrams, 2 is transistor circuit wherein 1 is probe, 3 is A.C. contactor, 4 is water pump.
Embodiment
Invention is by popping one's head in（1）, transistor circuit（2）, A.C. contactor（3）And water pump（4）Composition, probe（1）Water level information in water tank is detected, and is transferred to transistor circuit（2）, transistor circuit（2）Control A.C. contactor（3）And then control water pump（4）Draw water；Probe（1）Including electrode P1, electrode P2, electrode P3, electrode P1 is in water tank upper, and electrode P2 is in the middle part of water tank, and electrode P3 is in water tank bottom；Transistor circuit（2）Including transistor Q1, resistance R1, potentiometer W, relay J1, diode D1 and D2, relay J1 includes coil J1 and contact J1；A.C. contactor（3）Including coil C and contact C1, C2, C3, C4, contact C1, C2, C3 are normally opened, and coil C is closed when being powered；Contact C4 is normally closed, and coil C disconnects when being powered.Resistance R1 and potentiometer W partial pressures provide transistor Q1 base bias, D1 and J1 parallel connections are followed by the colelctor electrode in transistor Q1, and D2 is connected on transistor Q1 emitter stage, and electrode P3 is connected to power supply 12V, electrode P2 and A.C. contactor（3）Contact C4 series connection after be connected to resistance R1, electrode P1 is directly connected to resistance R1.A.C. contactor（3）Coil C connected with the contact J1 of relay, contact J1 is normally closed；Flow contactor（3）Contact C1, C2, C3 be connected to water pump（4）Three-phase coil.
In this experimental example, knife switch connects 380V three-phase alternating-current supplies, and when knife switch closes, control circuit will complete automatic pumping control.Its course of work is that, when waterline is less than electrode P2, transistor Q1 ends without base bias, relay J1 no currents and make contact J1 close, cause A.C. contactor（3）Coil C be powered, contact C1, C2, C3 connect, contact C4 disconnect, water pump（4）Work is drawn water, and water level rises；When water level rises to electrode P2, because contact C4 has disconnected, transistor Q1 base current can not be provided, transistor Q1 keeps cut-off, continues to draw water；When water level reaches electrode P1, electrode P1 is supplied to transistor Q1 base currents, causes transistor Q1 to be powered, and relay J1 work, contact J1 is disconnected by being closed into, A.C. contactor（3）Coil C power-off, contact C1, C2, C3 disconnect, contact C4 closure；Work as water level decreasing, but when electrode P2 is still immersed in water, electrode P2 provides base current by contact C4 for transistor Q1, keeps working condition, and state of drawing water also is kept；When water level decreasing is to below electrode P2, transistor Q1 is provided and ended without base current again, repeats pump process.
In this experimental example, resistance R1 is 10k, and potentiometer W is 5k, and transistor Q1 uses 8050, and diode D1, D2 use 4148, and relay J1 uses J-121 type supersensitive relays, A.C. contactor（3）Using C1-CJO-40 types, transistor circuit（2）Power supply use 12V DC power supply.
