Embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

A kind of multi-functional full-automatic water level controller, it is to constitute by movement circuit is installed in the flat box-shaped shell, on shell [1] leading flank 8 binding post a is arranged ₁, a ₂, a ₃, a ₄, a ₅, a ₆, a ₇, a ₈, referring to accompanying drawing 1.

The movement circuit board is installed in the shell 1, and movement circuit is by K switch ₁, K ₂Power transformer T, diode rectifier bridge D ₁-D ₄, relay J and contact J thereof _H, control chip IC, triode Q ₁, Q ₂, diode D ₅, LED ₁, LED ₂, LED ₃, resistance R ₁-R ₈, capacitor C ₁-C ₃Being electrically connected is connected into multi-functional full-automatic water-level control circuit, and referring to accompanying drawing 2, IC chip model is NE555.

When the utility model is used to control being connected when being communicated with the water system that sink [5] forms through water pump [3], water pipe [4] by upper pool [2] shown in the accompanying drawing 3, at this moment, the wiring pile a of multi-functional full-automatic water level controller ₁, a ₂Connect to hand over and cross AC220V power supply, wiring pile a ₃, a ₄Be connected to water pump [3] motor M, a ₅, a ₆, a ₇, a ₈Be connected to water-level probe A, B, F, E respectively, water-level probe B is again through resistance R ₈Be connected to water-level probe G, the full-water level position that probe B places upper pool [2] to set, the lowest water level position that probe A, G place upper pool [2] to set, probe E, F place sink [5] lowest water level position.

Principle of work is as follows:

(1) water supply control: with K switch ₁, K ₂Be connected to a little 1 position respectively, connect the AC220V AC power through transformer T and rectifier bridge D ₁-D ₄Provide dc supply to control circuit.

When upper pool [2] middle water level was lower than probe A, G position, probe A, G and water broke away from, and the IC chip 2., 6. the pin electric current is zero, and IC is pin output noble potential 3., through R ₃To the b utmost point of triode Q, Q ₁Saturation conduction, relay T energising, its contact J _HSplice grafting water flowing pump motor M, pump working draws water to upper pool [2], at this moment pilot lamp LED ₁Bright, LED ₂Put out, upper pool [2] middle water level rises gradually.

When upper pool [2] middle water level rose to the probe B position, water contacted with probe B, and IC 6. pin obtains noble potential, and 3. pin current potential vanishing of IC, relay J dead electricity, contact J _1-1Disconnect the motor M feed circuit, water pump quits work, and can prevent pond [2] water spill-over water, at this moment, and pilot lamp LED ₂Bright, LED ₁Put out.

When pond [5] water level was lower than probe E, F position under water, probe E, F and water disengaged, and the electric branch road that E, F connect through water disconnects triode Q ₂The vanishing of b electrode potential, Q ₂End, IC 4. pin obtains zero potential, LED ₃Extinguish, IC 3. pin becomes zero potential, makes relay T dead electricity, contact J _HDisconnect the motor M feed circuit, water pump quits work, thereby can prevent that the water pump tick over from burning out motor M.

(2) draining control:

When the utility model was used for draining control, referring to accompanying drawing 4, water was discharged through water pipe [4] by water pump [3] from upper pool [2], and this timed unit is with K switch ₁Be allocated to 1, K ₂Be allocated to 2, the E that will pop one's head in, F short circuit, LED ₃Bright.

When water level was higher than probe B in the water level, probe A, B connected circuit by water, and IC 6. pin obtains noble potential, and IC is the pin zero potential 3., relay J energising, contact J _HClosure, LED ₁Bright, LED ₂Extinguish pump motor M energising, pump working draining; Decline of water table is between probe A, B the time, IC 2. 6. pin still be high potential, the relay J adhesive of still switching on, the water pump draining that works on, when decline of water table when probe A is following, probe A breaks away from water, IC 2. 6. pin be zero potential, IC 3. pin is a noble potential, and relay J discharges, contact J _HDisconnect, water pump quits work, LED ₁Extinguish, LED ₂Bright.The unlikely idle running of same protection pump motor M burns out.

(3) when the utility model control circuit breaks down, can adopt manual operation, with K switch ₁Be allocated to 2, the control worker does not work on the road, by K switch ₁, directly connect electric pump motor M power supply, pump working.In the time of must shutting down, with K switch ₁Be allocated to 0, K ₁Disconnect, water pump shuts down.

But the utility model advantage is automatic controlling water supplying, draining, both can prevent storage cistern water spill-over water, again can Water pump idle running burns out motor when avoiding feed cistern anhydrous, and has manual operation switch, when control circuit is malfunctioning, Manual operation still can guarantee normal operation.
