Abstract
The utility model relates to a water level inductive controller. The utility model is provided with a power supply circuit, a detecting circuit, and a control circuit. Probe heads (3) (4) and a base pole (2) use water as a conductive body. A water level signal is detected and is supplied for the control circuit, and a water pump is controlled to work through the suction and release control of a relay J1 for realizing the automatic control of water level. The utility model which has the advantages of accurate detection for the water level, high sensitivity for automatic control, high work reliability, good safe performance, long service life, low cost, and little production investment is a wide automatic control device for industrial water and domestic water.
Description
The utility model relates to a kind of water-level control apparatus, particularly a kind of induction type water level controller that is used for water tower, pond, the control of well water level.
At present, the automatic control technology of water level is used very extensive, and the particularly water level in water tower or pond control is the assurance of industry and domestic water.In the prior art, the technology that is used for water level autocontrol mainly contains three kinds of float-ball type, photo-electric and electric pole types.The float-ball type control circuit is comparatively simple, and cost is low, but serviceable life is shorter, and is bad easily, can not automatic control; The control circuit complexity of photo-electric and electric pole type, operation circuit is many, because electronic component is many, is easy to generate fault, causes out of controlly, and influence is used, and the cost cost of control device is higher.
The purpose of this utility model is for the shortcoming that overcomes above-mentioned prior art provides a kind of water level induction controller, with simple structure, and the automatic control of high reliability guaranteed water level, the use of convenient industry and domestic water.
The purpose of this utility model can realize by following measure: this controller is by two secondary winding power supplies of transformer, in the pond, be provided with a basic utmost point at least, a high-order probe and a low level probe, high-order probe is connected one group of contact of relay with the low level probe, can inhale to connect or discharge and disconnect, the low level probe positions is lower than high-order probe in the pond, the position of the basis utmost point is lower than the low level probe, the basis utmost point is with high, can connect by water between the low level probe, the basis utmost point is connected secondary winding and bridge rectifier circuit respectively with high-order probe, two divider resistances of bridge rectifier circuit output terminal series connection, the base stage of control triode is connected between two divider resistances, the collector of control triode connects to inhale puts transistor base, suction is put transistor collector and is connected relay, one group of contact of relay connects height, the low level probe, another group contact connects the suction pump power supply, another secondary winding output of supply transformer is by putting transistor base through resistance connection control transistor base and suction respectively behind the diode rectification, also connect relay, the negative terminal of rectification connects the positive output end of bridge rectifier circuit.When the basic utmost point when water is connected probe, bridge rectifier circuit has output, control transistor base voltage is reduced to negative pressure and ends, and inhales to put transistor base voltage and raise and conducting the relay adhesive; When water level is lower than the basic utmost point and opens circuit, the bridge rectifier circuit no-output, the control transistor base is in noble potential and conducting, inhales that to put transistor base voltage low and end, and relay discharges, and utilizes the suction of relay to put control suction pump power supply.Thereby realization water level autocontrol.
Concrete structure of the present utility model and embodiment are provided by following figure:
