Description
The utility model relates to a kind of water level automatic control device.
Existing automatic control of liquid device has only the simple function of control water tower level, and adopts direct current to detect, and the electrolysis corrosion phenomenon all occurs when these devices of long-time use, be prone to fault, and the chemical substance that electrolysis is separated out pollutes to water quality.
The purpose of this utility model provides a kind of full-automatic water tower well fluid level controller, and it can control the liquid level of water tower (pond) and well simultaneously, and detecting electrode can polluted water.
The utility model reaches by following technical measures: controller has an elementary transformer B who joins with electrical network, its secondary coil is connected to rectifier UR, be characterised in that: the out-secondary of transformer also links with water level control electrode a, a ' and b, the b ' that are located in well and the water tower respectively, and a, a ' are through resistance R

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof
Accompanying drawing is circuit theory diagrams of the present utility model
As shown in FIG., entire circuit by transformer B electrical network is isolated and step-down is 12 volts of alternating currents, wherein one the tunnel after rectifier UR rectification, send direct current and use for control circuit, the level detection of water level control electrode c, a, a ' and c, b, b ' supply well and water tower is delivered on another road, owing to adopt alternating current, avoided direct current to detect the phenomenon that produces the electrode corrosion polluted water.
Control circuit is taken into account the water level control of well and water tower (pond) simultaneously, and c, a, a ' and c, b, b ' are respectively the water level detecting electrode that is located in Be Controlled well and the water tower.Direct current through rectification output is delivered to resistance R

When the well water level is in when drawing water scope, its detecting electrode c, the detected AC signal of a, a ' are handled the back through JB and are exported a direct current signal, are BG
1Provide bias current, BG
1Conducting, simultaneously, BG
2The ground level current potential descends.This moment, it detected electricity level c, b, the detected AC signal of b ' can not make BG if water tower does not reach certain water level and is in the lack of water position
2Conducting, the relay J no current is by not adhesive, its normally closed contact J
2To drive A.C. contactor CJ work, driven by motor water pump D draws water: the arrival designated water level if water tower level has risen, the detected AC signal of detecting electrode is through JB
2Handle back output one direct current signal, be BG
2Provide bias current, BG
2Conducting, J
2Disconnect, water pump stops pumping.Circulation is carried out according to this, and the controller with this circuit connecting mode can be intake water tower or pond automatically when lack of water, can keep water level certain in the water tower again and can not surpass the upper limit.
In addition, if the well water level has been low to moderate in the time of can't drawing water, not in water, then not having alternating-current detection signal provides JB for detecting electrode c, a, a '
1Can not export direct current signal, BG yet

2All disconnect, CJ is release, and water pump quits work automatically, and protection motor and water pump are unlikely idle running and burn out the protective effect of promptly dallying.A, a ' and b, four positions of electrode in water of b ' can be adjusted arbitrarily, if only use water tower (pond) control function during use, can be with a, c short circuit, and convenient, flexible.Circuit breaker J is the control output element, by its contact the control detection circuit is all isolated with electrical network, guarantees safety, D
2For circuit breaker shields.
The utility model structure and circuit are simple, reliable operation safety, and multi-use, the life-span is long, and is easy to install, saves electric power and polluted water not.
