Description

The electronics automatic controller for water level

Technical field

The utility model relates to a kind of water-level control apparatus, particularly a kind of electronics automatic controller for water level that is suitable for occasions such as pond, water tower.

Background technology

Pond, water tower, tank etc. are used for retaining and water supply, realize normal water supply, must earlier water be drawn up storage from the water source, supply water to the user by water pipe then again.Its control device that draws water adopts mechanical interlock mode to control pump working, utilizes SEA LEVEL VARIATION, by the mechanical mechanism controls switch, finish the control procedure of drawing water and switching off the pump, its shortcoming is a complicated in mechanical structure, installs and uses trouble, poor reliability, fault is many, and serviceable life is short; And the employing electronic circuit control, three water-level probes are generally arranged, one of them high water stage probe, a low-water level probe, another is the lowest water level probe, when water tower level touches the high water stage probe,, cut off the electricity supply by control circuit, stop pumping, when water tower level drops to low high water stage probe,, make power turn-on by control circuit, pump working, thereby keep water tower level within the specific limits, its shortcoming is the operation circuit more complicated, easy break-down, be difficult to maintenance, inconvenience is installed, and because its water-level probe is perishable, thereby influence the reliability and the serviceable life of its work.For improving above-mentioned situation, people have designed many automatic controller for water level, as patented claim 02214433.1, its electric current by water-level probe is an alternating current, and probe is not vulnerable to corrosion, and is easy for installation, but operation circuit or more complicated, in case be out of order then be difficult to maintenance, and can produce harmful brine electrolysis, thereby influence it and apply.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and provides a kind of operation circuit simple, safe and reliable electronics automatic controller for water level.

The purpose of this utility model can realize by following technical measures: this controller has transformer, the output terminal of transformer is connected to magnetic latching relay, magnetic latching relay is connected to height, low water level sensor, high, connect with magnetic latching relay again after the low water level sensor parallel connection, high, low water level sensor is provided with housing, the housing both ends are provided with positive stop lug boss, diode in series is arranged in the housing, tongue tube, the housing outside is set with floating part, be equiped with magnet on the floating part, floating part and magnet can move up and down between housing two positive stop lug boss, when floating part left tongue tube, tongue tube disconnected, and floating part is during near tongue tube, tongue tube is by the magnet adhesive, the positive extreme direction of the diode of low water level sensor is connected with magnetic latching relay, and during the tongue tube adhesive of low water level sensor, the magnetic latching relay forward is connected, adhesive is connected the pump motor power supply and is drawn water, and keeps the pump motor power supply to draw water; The negative pole direction of the diode of high water level sensor is connected with magnetic latching relay, and during the tongue tube adhesive of high water level sensor, magnetic latching relay disconnects oppositely to be connected, and disconnects the motor power that switches off the pump, and stops pumping.In actual applications, high and low level sensor is installed in the pond correct position respectively, and joins and suitable weight, make its location, when water level was reduced to the tongue tube position of low water level sensor, the energising of magnetic latching relay adhesive feed pump was drawn water; When water level rose, floating part also rose, and magnet leaves the tongue tube position, and tongue tube disconnects, and magnetic latching relay also keeps adhesive, continued energising and drew water; When water level rose to the tongue tube position of high water level sensor, magnetic latching relay disconnected pump power, stops pumping, and finishes the whole control procedure of drawing water automatically so repeatedly.

The utility model is reasonable in design, utilizes the tongue tube adhesive in the high and low level sensor and disconnects control water level, automatically controlled water pump work, have simple in structure, easy to use, the reliability height, operating maintenance is convenient, and economical and practical advantage is widely used in water level and controls automatically.
