The utility model comprises a high and a low level probes which are connected in series and arranged in a control relay power supply return circuit together, and a normally open contact of a relay is connected in series and arranged in a motor power supply return circuit. The utility model has the advantages of simple structure, reliable use, and low cost.
Description
The utility model relates to water level controller.
In a lot of areas, need to use the electric water pump groundwater abstraction, and water is pumped in the water tank of eminence, required for life.Be applied in the automatic control of liquid device in this water tank in the prior art, its water-level probe mostly is the water conductive switch, because the resistance of water is big, probe is starting relay directly, thus need after signal amplifies, just can make relay work, simultaneously, because power output is low, drive the pump working about 1KW, essential corresponding increase device brings cost height, big, the installation inconvenience of volume thus.In addition, because water conduction, the easy oxidation of popping one's head in causes out of controlly, and functional reliability is affected.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of simple in structure, service-strong water level full automatic controller is provided.
The purpose of this utility model is achieved through the following technical solutions:
Design feature of the present utility model is to adopt mercoid switch formula water-level probe or float-ball type magnetic switch water-level probe, comprise high-order probe K 2 and low level probe K 3, described high low level probe K 2, K3 series connection are arranged in the electric power loop of control relay coil J2, and this relay normally open contact j2 series connection is arranged in the motor power loop; Lock-up relay is set, its coil J1 and relay J 2 coils from parallel connection of coils, its contact j1 is in parallel with low level probe K 3.
The purpose of this utility model also can be achieved through the following technical solutions:
Be set to described control relay and lock-up relay the mu balanced circuit of working power is provided, this circuit comprises the current rectifying and wave filtering circuit that is made of diode D1, D2, capacitor C 1, and the three-terminal voltage-stabilizing ic chip.
Compared with the prior art, the utlity model has following advantage:
1, the utility model is owing to adopt mercoid switch formula or float-ball type magnetic switch water-level probe, and its signal output capacity is big, and directly starting relay work has reduced signal amplifying system, and not only cost reduces, and functional reliability is improved.
2, the utility model power output is big, can directly be used for controlling electricity and use water pump, and volume is little, is convenient to install.
3, the utility model has solved the probe oxidation problem out of control that exists owing to employing water conduction formula switch in the prior art, and its probe switch can be isolated with water.
4, the utility model is provided with voltage-stabilizing system by increase, makes still can guarantee operate as normal when line voltage is reduced to 160 volts.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model mercoid switch formula water-level probe structural representation.
Fig. 3 is the utility model float-ball type magnetic switch water-level probe structural representation.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to Fig. 1, present embodiment adopts mercoid switch formula water-level probe or float-ball type magnetic switch water-level probe, comprises high-order probe K 2 and low level probe K 3.High low level probe K 2, the common series connection of K3 are arranged in the electric power loop of control relay coil J2, and this relay normally open contact j2 series connection is arranged in the motor power loop.Lock-up relay is set, its coil J1 and relay J 2 coils from parallel connection of coils, its contact j1 is in parallel with low level probe K 3.
As shown in Figure 1, in the present embodiment, be set to the mu balanced circuit that control relay J2 and lock-up relay J1 provide working power, this circuit comprises the current rectifying and wave filtering circuit that is made of diode D1, D2, capacitor C 1, and the three-terminal voltage-stabilizing ic chip.
Referring to Fig. 2, mercoid switch is in sealing cavity volume 1 mercury bag 2 to be set vertically, and sealing cavity volume 1 is to be hinged on the fixed axis 3 with the one side.When water level rises, owing to buoyancy, sealing cavity volume 1 is held up is level, and mercoid switch is open circuit.Work as drawdown, because loss of buoyance, sealing cavity volume 1 tilts the mercoid switch closure together with the mercury bag in it.
Referring to Fig. 3, in order to be adapted to water level detecting, the magnetic switch that is adopted in the present embodiment should be the float-ball type magnetic switch.Along with the rising of water level, ball float 4 rises together with magnet ring fixed thereon 5, makes the disconnection of the switch in the tube 6 in being arranged on; Otherwise, after drawdown, switch closure.
The course of work is as follows:
Connect power switch K1, transformer T gets electric, three terminal regulator IC output direct current 12V voltage, and LED 1 indication power supply is normal.
When water level was higher than high-order probe K 2, K2, K3 were and cut-off, relay J 1, the equal dead electricity of J2, machine operation power supply open circuit.
When water level is lower than high-order probe, and when being higher than low level control, the K2 closure, K3 disconnects, and at this moment, relay J 2 coils still must not electricity, and motor is not still worked.
When water level was lower than the low level probe, K2, K3 were all closed, and at this moment, relay J 2 coils get electric, and motor is devoted oneself to work.While relay coil J1 gets electric, and its closing of contact drops into the self-insurance to K3.
When being higher than low level, rising of groundwater level pops one's head in, when being lower than high-order the probe simultaneously, and the K2 closure, K3 disconnects, but in because the self-insurance of relay J 1, control relay J2 still electric, motor remains in operation, and is higher than high-order the probe until rising of groundwater level, at this moment, K2, K3 are open circuit, so circulation.
