Abstract

The utility model provides an electronic water level controller. The utility model is composed of a power circuit, two sets of water level detecting circuits, and a control circuit, wherein, the water level detecting circuits respectively automatically detect the water level of a water tank and the water level of a water well, detection signals are sent to the control circuit, and a water pump is controlled to start or stop. The utility model has the functions that when the water level of the water well is not sufficient, and water is urgently needed, the water pump can be forcibly to start to pump the water; when the water level of the water well is too low, and the water is not proper to be continuously pumped, the water pump automatically stops. The utility model has the advantages of simple circuit, complete function, and convenient maintenance and operation.

Description

The electronics water level controller
The utility model relates to a kind of water level controller, particularly a kind of water tank, the electronics water level controller that the well water level detects automatically.
Raising along with scientific progress and people's living standard, drink, fire water box is more and more, the condensate tank of dehumidifier of various water tanks and well is Application and Development in succession, but there are some defectives to some extent, row fairly simple but automaticity is not high, have too complicated and make the cost of device higher and safeguard inconvenience.
The purpose of this utility model provides a kind of simple in structure, easy to maintenance, function is more and cost is low electronics water level controller.
The purpose of this utility model realizes by following technical proposals, and it is made up of power circuit, two groups of water level detection circuits and control circuit etc.Two groups of testing circuits detect the water level of water tank and well respectively and signal are sent into control circuit, so control water pump startup and close.
Control circuit is by R 3, C 5And J 1, D 6Back in parallel respectively series connection, an end and positive source link, another termination BG 4Collector, base stage is through R 7, C 4Series connection back is with emitter and connect power cathode and form.
A low level water level detecting e is through K in the water tank 3, normally closed contact J 1-1The series connection back is with the interior high-order water level detecting d of water tank and connect R 3, again through C 2, R 2Meet BG 1Base stage, form the cistern water level testing circuit.
Well bottom water level detection head b and normally opened contact J 1-2The series connection back is with the high-order water level detecting a of well and connect R 6, through C 3, R 5Meet BG 2Base stage is again through BG 2Anti-phase composition well water level detection circuit.
K switch 4One end is with detection head a and connect R 6, the other end (c, f are respectively well, water tank electric potential signal source) in parallel with c, f meets R 9One end, R 9Another termination power.
The utility model circuit is simple, multiple functional, existing well water storage is not enough but can start water pump by force when being badly in need of water and draw water, have again at well water and cross the low function that stops pump working in the time of should not continuing to draw water again automatically, the actual use under various conditions, have safe and reliable, operating maintenance convenient, advantage such as economical and practical.
Below contrast drawings and Examples, the utility model described in further detail,
Accompanying drawing is electronics water level controller circuit theory diagrams, and symbolic representation is as follows among the figure:
K 1-power switch K 2-manual switch
K 3-test switch K 5-change-over switch
A-well B-water tank
A, b, e, d-detection head c, f-electric potential signal source
J 1, J 2-relay BG 1~BG 4-triode
Learn that by accompanying drawing AC power is through the transformer isolation step-down, through D 1~D 4Rectification, C 1Be filtered into circuit dc supply is provided, R 10, D 7Series connection back and C 1Parallel connection is as C 1Stockpile the charge discharging resisting loop, to guarantee pump motor M smooth operation, D 7Be light emitting diode, indicate as power supply.By R 9, J 1, D 6, C 5, R 7, C 4And BG 4Form control circuit; By low-water level detection head e, test switch K 3, normally closed contact J 1-1, high water stage detection head d, R 3, C 2, R 2And BG 1Form the cistern water level testing circuit; By low-water level detection head b, normally opened contact J 1-2, high water stage detection head a, R 6, C 3, R 5, BG 3, R 4And BG 2Form the well water level detection circuit.
BG 1With BG 2Collector and connect R 1After connect positive source, and through D 5Meet R 7, C 2, C 3, C 4Respectively through R 2, R 5, R 7Meet BG 1, BG 3, BG 4Base stage, the other end also connects power cathode, wherein C 1, C 2Disturb C in order to absorption detecting 4Cushion in order to decoupling.
The course of work of the present utility model is such.
K closes 1, K 3When the low dried detection head e of water tank B water level, BG 1The base stage no current injects and ends, and this moment is if well A water level is higher than detection head a, BG 3Base stage must conduct, BG 2Also end, the H point is noble potential, BG 4Conducting, J 1The energising adhesive.J 1After the adhesive, normally opened contact J 1-3Closure makes J 2The energising adhesive, contact J 2-1, J 2-2Closure, pump motor M starts working.While normally closed contact J 1-1Disconnect, still keep BG when making cistern water level surpass detection head e 1Cut-off state, until cistern water level up to detection head d, BG 1Base stage must conduct.The H point is electronegative potential, BG 1End J 1Discharge J 1-3Disconnect J 2Discharge J 2-1, J 2-2Disconnect.Pump motor M quits work.
If well A water storage deficiency, or water tank B for some reason can not retaining to detection head d because pump motor M works always, cause well A water level to reduce to detection head b when following, owing to BG always 3Base stage is ended BG because of no detection signal electric current injects 2Conducting, the H point is an electronegative potential, BG 4End J 1Discharge J 2Discharge, pump motor M quits work, and rises to more than the detection head a until the well water level, and cistern water level is reduced to below the detection head e, pump motor M such as controlled resuming work.
If the low dried detection head a of well A water level, water tank B is anhydrous, and this moment, pump motor was not worked, and the user is badly in need of water, and hand switch K then can directly close 2Starting water pump by force draws water.
Test switch K 3Whether be in normal condition, when between dried detection head d in water tank B water level place and the detection head e, pump motor M does not work or works, the K switch of cutting off the electricity supply if being used for advance copy utility model circuit 1, pump motor M promptly quits work, and K closes 1Still do not work, if this moment is the open test K switch 3, water pump is promptly worked again, closes again, and water pump is still worked, and illustrates that circuit working is normal.
As the K that closes 4, then the water level detection circuit of well A is inoperative, and the testing circuit of water tank B is still normal, and the utility model can replace single container water level detecting controller.
If testing circuit and control circuit are malfunctioning or damage, hand switch K can close 2, directly make relay J 2Closure starts water pump M and draws water.
