Description

The water tower pond of the multiple full-automatic defencive function automatic controller that draws water is arranged

The utility model is water tower, pond that multiple full-automatic defencive function the is arranged automatic controller that draws water, and belongs to electrical application technology equipment.

Automatically the control of drawing water of present high-rise water tower (pond) is general, and to adopt two kinds of machinery or Electronic Control, mechanical control method be to utilize the automatic monitoring as water level of the ball float that is positioned in the water tower (pond).Driving corresponding switch or inlet valve is realized automatic control when ball float floats to the relevant position with water level, is the quite simple automatic control mode of a kind of structure.But this class mechanical control method exists a defective that can not be ignored, be exactly that ball float its activity space size when switch that directly drives or valve is all smaller, thereby the water-head up and down of controlled water level is also less, as user during at water, any falls in water level slightly is that the touch switch start is drawn water, replenish water inlet and ball float is moved and close water pumper and draw water, so again and again just cause the Water-pumping motor Fraquent start once start.And starting current is several times when normally moving, and not only causes the significantly increase of power consumption, but also can cause the very easily damage of motor and switch and other mechanical parts, so the life-span is short, fault rate is high.And present all kinds of electronic control mode generally adopts pass to low-voltage DC in the pond, replenish the low water stage point of water inlet and wish that the high water level point that stops pumping respectively is provided with a detecting electrode in hope again, utilize transistor or integrated circuit and relay etc. to constitute Auto Power On and shutdown control circuit, promptly similar bistable automatic pumping control circuit then.The advantage of this electron-like control mode is the high water level point that the lowest water level point when can be as required optionally determining voluntarily to need to replenish water inlet in the pond and wishing stops pumping after water level in the pond reach a certain height, thereby can avoid the Fraquent start of Water-pumping motor, its reliability and application life all are greatly improved.Control device all exists following shortcomings but draw water automatically in the pond of present all kinds of electronic control modes: the spark that its controlled contact switch open in usual of relay of (1) control motor power switch is produced when regular power on/off is sticked together its switch contact fusion sometimes, thereby make the water level in water tower, pond more and more higher thereby cause Water-pumping motor to close down and suction pump is drawn water always, even may cause water constantly to come down in torrents downwards from the top, pond.Not only cause meaningless waste but also can take place beyond thought as danger such as water loggings.As a same reason, (this fault all once appearred in many electronic automatic control circuits sooner or later) can cause suction pump to close down automatically too if the similar bistable circuit of control motor goes wrong; (2) existing each electron-like is controlled water plug mostly just has automatic monitoring to the water level in water pond effect automatically.Energising starts and draws water to Water-pumping motor when promptly being lower than down water level point, and water level in water pool promptly disconnects the Water-pumping motor power supply it is stopped pumping when rising to high water level point.And do not consider that at all will the switch on inlet channel that must consider the water pump that draws water when drawing water of the water pump that draws water must fill water and could start shooting and draw water, the inlet channel of water pump of drawing water does not else if having water, and (this is recurrent thing, the inlet channel of tap water pressure pump that for example is used for high-rise residential building is because of tap water cut-off or be used for river or well water taken out to leak etc. toward the inlet channel sealant of the water pump of high-rise water tower all causing the pump water inlet road that draws water anhydrous), when at this moment if Water-pumping motor is also switched on start in the same old way, not only take out, but also can cause the damage of the water pump that draws water less than water; (3) the water level situation in the pond does not have any sound, light shows, thereby can't the water level situation in pond be got information about; (4) pass to low-voltage DC because of the pond midium or long term, thereby make whole pond all be equivalent to become weak electrolyte and each is monitored electrode (for example copper electrode) and produce the corrosiveness that can not be ignored, only needed three or five days can make the copper conductive electrode surface in the pond generate the linen electrolysis product of one deck during practical application, the linen electrolysis product of this layer poor electric conductivity, so general continuous use in two to three months just must be struck off the bad electrolysis product of this layer conduction, otherwise a whole set of automatic water level monitor at any time all can " malfunctioning ".For avoiding this bad phenomenon, have to select for use materials such as graphite, carbon-point to make the water-level detecting head sometimes.But may be influential in this material long period of soaking water to drinking water hygiene, and its lead-out wire also draws with copper cash, so this is not best solution; (5) in practicality, the pond is on high building or high tower, and suction pump then is installed in well downstairs or the beneath floor place of tap water is arranged, thereby all long to the distance self-con-tained unit from the pond exploring electrode.The just possible induced interference signal of water-level detecting lead-in wire that it is long, and existing water-level detecting control device, its interference free performance is relatively poor, tends to cause mistake control.

The purpose of this utility model be exactly for overcome and solve existing water tower pond draw water the mechanical control method of control device exist the motor frequent starting, fragile, the life-span is short, fault rate is high, and electronic control mode exist relay switch contacts easily fuse adhesion cause in the accident of drawing water of can't closing down automatically, the suction pump water inlet pipe anhydrous and start draw water can't draw water and water pump fragile, noiseless, light shows water level situation, not directly perceived, the monitoring electrode easily generates electrolyte and makes the supervising device that draws water malfunctioning, is subject to disturb, easily produce the shortcoming and the problem of mistake control etc.; A kind of monitoring electrode of research and design can not generate electrolyte, do not influence water quality, reliability height, fault rate are low, have automatically anti-sealing to overflow function, be not afraid of malfunctioning, the unlikely appearance of the supervising device accident of can't drawing water; have sound, auroral poles police simultaneously; have automatic control/manual conversion equipment can guarantee continuity of pumping, automatic controller draws water in the water tower pond with full-automatic defencive function that antijamming capability is strong, guarantee the device reliably working, be provided with the water level in water pool indicator lamp, be convenient to observe.

Operating principle of the present utility model is as follows: at the low-voltage AC of secondary induction, the one tunnel through D by the elementary of wiring terminal G and H input AC transformer T for 220 volts electric main ₁, D ₂And C ₃Behind the rectifying and wave-filtering again through three-terminal regulator block IC ₁After the voltage stabilizing again by C ₂Become D.C. regulated power supply after the filtering and supply with each circuit application of complete machine.And another road of low-voltage AC is via the C that is connected into polarity free capacitor ₄, C ₅Deliver to wiring terminal A, be connected to exploring electrode d that is installed on basin bottom and the exploring electrode e that is installed on pump water inlet inside as " basic electrode of AC low-tension " by wiring terminal A again; Because what these two basic electrodes inserted is the one positive one negative low-voltage AC that constantly alternately changes, rather than the direct current of one-way flow, so can be by electrolytic etching even use common copper wire rod to make conductive electrode to other exploring electrodes in basic electrode itself and the pond yet.Thereby protected exploring electrode, and also protected water quality, also improved the reliability of complete machine and effectively increased the service life.And for this low-voltage AC that inserts by basic electrode in the pond, when the water level in the pond is lower than detection conductive electrode c, at this moment between wiring terminal B that is attached thereto and the terminals A owing to lose the conductive communication effect of water, so terminals B also can lose low-voltage AC simultaneously.Even and the sharp narrow disturbing pulse that may sense because its line is long, also because R is arranged ₁₅, R ₁₆, D ₁₄, D ₁₅, C ₁₁, C ₁₂Existence and cut little ice.Because its time constant is big more a lot of than sharp burst pulse, sharp narrow disturbing pulse is by filtering automatically effectively.So when the water level in the pond was lower than detection conductive electrode c point, the wiring terminal B that is attached thereto also lost low-voltage AC.And capacitor C ₁₁Original electricity that is filled is also because of R ₁₆Discharge process also can only keep about 1 second time.In other words: survey conductive electrode c point after about 1 second, capacitor C when the water level in the pond is lower than ₁₁Two ends become low level, and it is effective to be input as low level by its triggering of rest-set flip-flop that 1A, 1B, 1Y and 4A, 4B, 4Y among the IC (i.e. two inputs four and non-Schmidt trigger) form.So C ₁₁Low level make the 4Y pin of rest-set flip-flop be output as low level on the one hand, and the 3A through being connected into not gate, 3B, 3Y anti-phase after by 3Y output becoming high level, this high level makes triode BG again ₇Saturation conduction.And BG ₇Saturation conduction just caused controlled relay J ₂Adhesive, thereby make controlled switch KJ ₂The adhesive conducting.And KJ ₂Be and KJ ₁Be serially connected, and KJ ₁Be the normally closed relay switch, it only the water level in the pond will arrive that the super full-water level in pond is caused at the top, pond or when just being forced to during lack of water in the pump water inlet with KJ ₁Disconnect.Promptly generally speaking, KJ1 is closed, and artificial/automatic change-over Ka generally pushes automatic control on one side.The Ka3 point and the Ka1 point that are K switch a join, so Water-pumping motor M is access in 220 volts of AC powers and begins to draw water at this moment, and because triode BG ₇Saturation conduction, thereby also make the light emitting transistor LED be attached thereto ₅There is electric current to flow through and luminous, thereby sends the light indication that the water pump energising is drawn water.And on the other hand, capacitor C ₁₁Low level make the IC that is attached thereto again ₃In the not gate formed of 2A, 2B, 2Y be output as high level, this high level is through R ₁₇Make BG again ₈Saturation conduction and lighted LED ₆Light indication as the pond lack of water.And BG ₉Base stage be through R ₁₈Be connected to BG ₈Colelctor electrode, so BG ₈The saturated BG that caused ₉End, thereby this moment luminous tube LED ₇Do not have luminous demonstration; And when the water level in the pond draws water constantly rising arrival low water stage detection conductive electrode c because of start, because the connection electric action of water at this moment, also is to have connected low-voltage AC on the terminals B.This low-voltage AC is through R ₁₅, D ₁₄, D ₁₅, C ₁₁, C ₁₂, R ₁₆Rectifying and wave-filtering after become the direct current high level, but because of rest-set flip-flop be that low level triggers effectively.So the state of rest-set flip-flop does not change, suction pump still continues to draw water.But then, because capacitor C ₁₁Two ends become high level, and this high level is input to IC ₃In the not gate formed by 2A, 2B, 2Y become low level after anti-phase, this low level is through R ₁₇Make BG ₈Transfer cut-off state to by saturation state.So luminous tube LED of indication pond lack of water ₆Extinguish, and BG ₈By making its collector potential become high level from low level, this high level is through R ₁₈Be input to BG ₉And make BG ₉From having lighted luminous tube LED by transferring conducting to ₇, entered into down the light indication of water level as water level in water pool.

And when the water level in the pond rose to detection conductive electrode b always, because the conductive communication effect of water, terminals C had also connected low-voltage AC, and this low-voltage AC is through R ₁₃, D ₁, D ₁₂, C ₈, C ₁₃, R ₁₄Rectifying and wave-filtering after become the direct current high level, this high level is via IC ₂In by 1A, 1Y form behind the door non-, 1Y output has become the direct current low level, and the army branched out into two columns from this direct current low level of 1Y output, the one tunnel is connected to the 4A input of rest-set flip-flop, thereby RS is overturn.And the upset of RS makes the BG of original conducting ₇Transfer to and ending, the J2 relay discharges.Thereby controlled switch KJ ₂Also become disconnection, thereby also make Water-pumping motor stop drawing water by closure.And because BG ₇Transfer to and ending, so the indicator lamp LED of conduct " drawing water " ₅Also extinguish simultaneously, but then, by IC ₂In this low level of 1Y output through IC ₂In by 2A, 2Y form behind the door non-, 2Y output has become high level, this high level is through R ₂₀Make BG ₆Thereby enter conducting state and lighted the LED of using as the high water level indicator lamp ₄And in actual use, water level in the pond can descend gradually because of user's water, when the drawdown in the pond to surveying conductive electrode b below the high water level exploring electrode b but still when low water stage exploring electrode c is above, also having interrupted the effect that is communicated with the low-voltage AC basic electrode, promptly is that wiring terminal C also no longer includes low-voltage AC.Capacitor C ₈Also discharge off and become low level after 1 second, this low level is via IC ₂In after the not gate formed by 1A, 1Y, 1Y output has become high level, though this high level has also been received an input (IC of rest-set flip-flop ₃In 4A), but rest-set flip-flop is that the low level input trigger is effective, so that rest-set flip-flop is still kept original state is constant, then suction pump still keeps the stopped status of not drawing water.But by IC ₂This high level of middle output is then by IC ₂After the not gate that middle 2A, 2Y form was anti-phase, 2Y had become low level, and IC ₂In the low level of 2Y output again through R ₂₀And make BG ₆Become cut-off state, so just extinguish as the LED4 of " high water level " indication.And in actual use, water level in the pond can descend gradually because of user's water, when the drawdown in the pond to below the high water level exploring electrode b but still when low water stage exploring electrode c is above, surveying conductive electrode b and also interrupted the connection effect of low-voltage AC basic electrode, promptly is that wiring terminal C also no longer includes low-voltage AC.Capacitor C ₈Also discharge off and become low level after 1 second, this low level is via IC ₂In after the not gate formed by 1A, 1Y, 1Y output has become high level, though this high level has also been received an input (IC of rest-set flip-flop ₃In 4A), trigger effectively but rest-set flip-flop is low level input, so that rest-set flip-flop is still kept original state is constant, then suction pump still keeps the stopped status of not drawing water.But by IC ₂In this high level of 1Y output then by IC ₂In the not gate formed by 2A, 2Y anti-phase after, 2Y has become low level and IC ₂In the low level R of 2Y output ₂₀And make BG ₆Become cut-off state.So, as the LED of high water level indication ₄Just extinguish.

And continuing to drop to conductive electrode c when following when the water level in the pond, the wiring terminal B that is attached thereto has not had low-voltage AC again, capacitor C ₁₁After 1 second, also become low level because of discharge off.This low level makes the rest-set flip-flop state that upset takes place again and makes relay J ₂Transfer adhesive again to, original KJ that disconnects ₂Also transfer closure to and connect the power supply of Water-pumping motor, thereby water pumper begins again to draw water.And when the water level in the pond was raised to high water level detection conductive electrode b, as mentioned above, rest-set flip-flop overturn again, relay J ₂Discharge controlled switch KJ ₂Disconnect, because of cutting off the power supply and having stopped drawing water ... so move in endless cycles, the water level in the pond remains between low water stage and the high water level all the time automatically.Actual water level situation in the pond then can clearly show from being loaded on the light emitting diode of respectively representing different water levels on the automatic controller shell; If the relay switch KJ open in usual that control is drawn water is described now again ₂Just in case when because of long-term power on/off switch spark the switch adhesion having taken place, when perhaps causing suction pump constantly to draw water because of the rest-set flip-flop fault, the water level in the pond will surpass high water level detection conductive electrode b and can not shut down.But when the water level in the pond rose to super full-water level and surveys conductive electrode a, situation just at once can be controlled, and this is because the conductive communication effect of water, makes also to have connected the pond mesolow on the wiring terminal D pin and exchange the low-voltage AC that basic electrode d sends here, through R ₁₁, R ₁₂, C ₇, C ₁₄, D ₁₀, D ₁₁The rectifying and wave-filtering effect and become the direct current high level, this direct current high level is through IC ₂In be still high level with twice after anti-phase by the join isolation that forms of 6A, 6Y and 5A, 5Y two not gates.This moment IC ₂In the high level of 5Y output carried out separately hot job by the army branched out into two columns again, the one tunnel through D ₆, R ₂₃And make the BG that is in cut-off state usually ₄Enter conducting state, force cut-off relay J at once ₁Adhesive, thus make the normally closed switch KJ that is serially connected with Water-pumping motor controlled switch group ₁Horse back transfers off-state to from the normally off under the routine.Thereby suction pump outage and horse back are stopped pumping, thereby guaranteed that the water level in the pond is unlikely the danger that occurs overflowing, from IC ₂Another road that the high level of middle 5Y output arrives is through R ₂₂Make BG ₅Enter conducting state, thereby lighted LED as super full-water level indication usefulness ₃From IC ₂The high level of middle 5Y output also has been sent to diode D ₇Negative pole end, D ₇Become reverse blocking state by original conducting state, thereby by IC ₂4A, 4Y the Schmidt's not gate and the C that form ₉And R ₂₁The audio frequency oscillator of forming starting of oscillation at once, this audio oscillator signal is again through C ₁Be coupled to by BG ₁, BG ₂The Darlington single-stage power amplifier of forming amplifies the back by the loudspeaker Y alarm signal of sounding, and reminds the related personnel that the control of drawing water automatically partly fault occurred, so that in time keep in repair or temporarily forward to manual control switch's machine.

In addition; the anti-excessive low water level protection operation principles of suction pump water inlet pipe is described again: the detection of another in pump water inlet conductive electrode water inlet pipe lack of water detection conductive electrode f passes on the wiring terminal F low-voltage AC on the low-voltage alternating-current basic electrode e when the suction pump water inlet pipe has water in its pump water inlet by the conductive communication effect of water, and this low-voltage AC is through R ₉, D ₈, D ₉, C ₆, C ₁₅, R ₁₀The rectifying and wave-filtering effect after become the direct current high level, this direct current high level is through IC ₂It is behind the door non-that middle 3A, 3Y form, and just become the direct current low level by the 3Y output, and this low level both can't make BG ₃Conducting also can't be passed through D ₅Enter BG ₄So when in the pump water inlet not during lack of water, control is drawn water automatically, and things are as usual for part, not influenced.But when the water inlet pipe lack of water of water pump, situation is just different.At this moment, just there has not been low-voltage AC on the wiring terminal F.When water inlet pipe lack of water after 1 second, capacitor C ₆On also discharge off become the direct current low level, this low level is through IC ₂In not gate 3A, 3Y anti-phase after, by 3Y output high level.The army branched out into two columns for this high level, and one the tunnel through D ₅With R ₂₃Make BG ₄Enter the saturation conduction state, force cut-off relay J thereby make ₁Adhesive and with normally closed switch KJ ₁Disconnect, thereby not only avoided the electricity wasting of pump motor, also protected the safety of water pump and motor; And be through R by another road direction of this high level of 3Y output ₂₄And make BG ₃Enter conducting state, thereby lighted LED as lack of water light indication in the pump water inlet ₂, to remind the relevant personnel's attention; And if whole on the other hand automatic control system is when damaging; do not worry yet; because this moment is as long as pull artificial/automatic change-over Ka to artificial one side; be that Ka3 point among the selector switch Ka and Ka2 point are when joining; can draw water and be unlikely influence with the control of artificial method of operating continuation open and close machine and supply water normally; thereby protected the continuity that supplies water, also for keeping in repair or replacing another self-con-tained unit and won the time.Water-pumping motor in the practical example that the utility model is lifted here is a situation of using 220 volts of single-phase alternating currents.But also can alternative use in three phase alternating current motor, this moment is as long as receive three-phase ac contactor to the three-phase alternating current motor, and two terminals of the access of the pulling relay coil in A.C. contactor Fig. 3 Central Plains tag splice motor M of institute got final product when promptly the A.C. contactor pull-in winding is 220 volts (if situation) again.When being 380 volts wiring terminal I and wiring terminal J also reconfiguration to 380 volt alternating current is got final product as A.C. contactor.So the utility model both can be used for the control of drawing water automatically of full guard in the small-sized pond of family expenses, also can be used for the Automatic Control of drawing water of the large-scale water supply water tower of water works, as seen its practicality is great.
