Abstract
The utility model relates to a water level controller, which belongs to a water tower or well water level automatic control device. The water level controller is composed of a transformer, a rectifying filter circuit and a control circuit. Signals are provided by two control points a and b in water; triodes BG[1] and BG[2] are mutually conducted and cut off for controlling the starting and stopping of a motor. The utility model has simple circuit, reliable work, convenient installation and use, no attracting of relays under normal state, electricity saving and long lifetime. The water level controller can automatically control the water level of a water tower, and can also control the water level of a water well or a water pool.
Description
The utility model belongs to a kind of water tower or pond (well) automatic control of liquid device.
Present many water towers mostly are equipped with automaton, but it is reported, these control device are the circuit complexity mostly, and install and use not too conveniently, because the circuit complexity, control system breaks down easily, is not easy to maintenance again.Also there is not well Water Level Control device at present, decline of water table sometimes, water inlet can surface, and causes motor idle running, burns out equipment.
The purpose of this utility model is a kind of water level controller of design, and this water level controller circuit is simple, reliable operation, and electric power is saved in not adhesive of relay under normal condition.
Circuit of the present utility model is by coil B(4), filter rectifier (3), control circuit (2) is formed, and reference mark a, b are located among controlled water tower or the well, and a point is through resistance R
1Connect positive source, the b point is through resistance R
2Meet triode BG
1Base stage, BG
1Collector and emitter connect power cathode; Triode BG
2Base stage through resistance R
3Connect positive source, the coil of collector connecting relay J, emitter is through capacitor D
3Connect power cathode.
Just control water tower level and pond respectively or the well water level is described in detail below in conjunction with accompanying drawing.
The circuit of Fig. 1 is used for controlling the water tower middle water level, and b is a lower-limit point, and b ' is a upper change point, will keep certain water level because of water tower but can not surpass the upper limit, so when 2 of a, b are all in water, by resistance R
1, R
2And the resistance in the water is triode BG
1Provide bias current, triode BG
1Conducting, BG
2End; When 2 of a, b leave the water surface more arbitrarily the time, BG
1End R
3Be triode BG
2Provide bias current, BG
2Conducting makes to be connected on BG
2The relay J adhesive of collector, the normally opened contact closure of relay J, normally closed contact disconnects, thereby makes A.C. contactor CJ adhesive action, motor D operation, water pump just begins to supply water in water tower; B and b ' are two points in parallel, are connected to one group of normally closed contact of relay J on the lead that connection b is ordered, and normally closed contact disconnects after the relay J adhesive, so water pump is when work, when having only water level to reach the b point, at this moment by R
1, R
2With the resistance in the water be triode BG
1Provide bias current, triode BG
1Conducting, triode BG
2End, relay J disconnects simultaneously, and A.C. contactor CJ quits work.
The circuit of Fig. 2 is the water level that is used for controlling pond or well.Because draw water for a long time, can make the decline of water table of pond and well a lot, the water inlet of pump can surface sometimes, will cause motor idle running like this, a waste electric power, two burn out motor easily, and three damage water pump.2 of a, b are located in the well or in the pond, when 2 of a, b are all in water, and resistance R
1, R
2And the resistance in the water is triode BG
1Provide bias current, triode BG
1Conducting, BG
2End.At this moment, if need draw water, can start and open knob QA, energized makes pump working.After being extracted into certain hour, 2 of a, b surface triode BG more arbitrarily
1End, and by resistance R
3Be triode BG
2Provide bias current, BG
2Conducting, the relay J adhesive, its normally closed contact disconnects, and A.C. contactor disconnects, and motor quits work, and this has just been avoided water level to cross motor idle running when hanging down, and has protected equipment, has saved electric power.The position that a, b are 2 can be adjusted arbitrarily.
The utility model has the advantages that, circuit is simple, reliable operation, not adhesive of relay under the normal condition, power saving, life-span are long, multi-use, easy to install.
