Abstract
The utility model relates to a protector against the water shortage of a water pump, which comprises a shell, a membrane sheet in a containing chamber in the shell, a pressure block and a pressure spring, wherein the shell is provided with a water inlet and a water outlet, the containing chamber is communicated with the water inlet and the water outlet, and the pressure block and the pressure spring are pressed on the membrane sheet; a check valve which is provided with a magnet is arranged in the water inlet, a magnetic control element is arranged on a position which corresponds to the magnet, and the magnetic control element is connected with a control circuit. When a water pool or a water well is short of water, the check valve falls back, the magnet acts on the magnetic control element, and the water pump is caused to stop working through the control circuit. The utility model has the advantages of accurate control, no requirement of accessory installation under water, simple installation and wide sphere of application.
Description
Technical field
The utility model relates to pump part, particularly a kind of electronic auto-control device of water pump.
Background technique
Water pump is when draining, and the water in pond or well is taken out to the greatest extent, and water pump idle running is not only wasted electric energy, and made water pump pump chamber lack of water, needs water filling again, troublesome poeration when reusing.A kind of water level controller appears recently, utilize ball float perception water level, as Chinese patent 99236731.X disclosed " full-automatic water level controller ", be in the ball float of sealing steel ball, switch to be set, switch is drawn by electric wire, and one end of electric wire is fixed on the pool wall during use, when ball float rises or descend, ball float and horizontal angle of inclination change, and steel ball makes switch motion because action of gravity is slided, and realizes opening or closing.This device need be fixed on an end of electric wire on the pool wall, can't install in some wells, has limited use; In addition owing to influenced by the mounting point, be difficult for accurately being controlled at water and just take out and water pump is quit work when most.
Summary of the invention
The utility model purpose is to provide a kind of water pump water shortage protective device by water flow control, with the raising precise control, and makes its installation simple, applied widely.
Scheme of the present utility model is: the diaphragm in the cavity volume that this device comprises in a housing with water intake and water outlet, the housing with intake-outlet communicates and be pressed on briquetting and stage clip on the diaphragm, in water intake, be provided with safety check, safety check is provided with magnet, be provided with the magnetic control element with the magnet opposite position, the magnetic control element is connected with control circuit.
The utility model has the advantages that: owing to be provided with safety check in water intake, in the pond or during the well lack of water, safety check falls after rise, magnet and the effect of magnetic control element, and water pump is quit work by control circuit.Advantage with precise control, and do not need installation accessories under water, install simple, applied widely.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is the utility model cross-sectional view.
Fig. 2 is the utility model structure explosive view.
Fig. 3 is the utility model circuit theory diagrams.
Among Fig. 1, Fig. 2,1 housing, 2 water intakes, 3 safety check, 4 magnet, 5 check-valve springs, 6 water outlets, 7 diaphragms, 8 briquettings, 9 stage clips, 10 control circuits; K wherein
1Be the magnetic control element, K
2It is switch.
Embodiment
By shown in Figure 1, diaphragm 7 in the cavity volume that the utility model comprises in a housing 1 with water intake 2 and water outlet 6, the housing 1 with intake-outlet communicates and be pressed on briquetting 8 and stage clip 9 on the diaphragm 7, in water intake 2, be provided with safety check 3, safety check 3 is provided with magnet 4, is provided with magnetic control element K with magnet 4 opposite positions
1, K
1Be connected with control circuit 10.The magnetic control element can adopt dry reed-pipe or Hall unit, and what present embodiment adopted is dry reed-pipe.
Briquetting 8 one sides are provided with K switch
2, its button and briquetting 8 contact K switch
2Be connected with control circuit 10, be used for the mobile status of perception diaphragm 7, play the stroke switch.
In conjunction with each figure, when lack of water, safety check 3 falls after rise under the effect of check-valve spring 5, cuts out, and magnet 4 is dry reed-pipe away from magnetic control element K1, and this moment, K1 disconnected, delay time through the delay circuit that resistance R 3, capacitor C 2 are formed, the input end of not gate F1 is high level " 1 ", and F1 exports " 0 ", and triode T2 ends, relay J discharges, and control of pump quits work.This moment, diaphragm 7 was compressed back owing to lack of water, and briquetting 8 descends, and K switch 2 is connected, and F2 input end " 0 " goes out " 1 ", and luminotron tube LED is bright, the indication lack of water.
Vcc is a positive source among the figure, and R4 is the biasing resistor of T2, and R5 is the current-limiting resistance of LED, and D is a T2 protection diode, and R6 is the pull-up resistor of F2.
When restarting, press start button AN, make C1 be discharged to low level, the T1 conducting, C2 discharges through R2, and F1 imports " 0 ", goes out " 1 ", T2 conducting, J adhesive, pump working.This moment, diaphragm 7 was backed down, and briquetting 8 rises, and K switch 2 disconnects, and F2 input end " 1 " goes out " 0 ", and luminotron tube LED does not work.After decontroling AN, because the charging of R1, C1 time-delay, above working state can be kept in this time, after water pump draws water normally, safety check 3 is pushed open by water, and magnet 4 is near dry reed-pipe K1, the K1 closure, and F1 imports " 0 ", go out " 1 ", T2 continues conducting, and J continues adhesive, and water pump works on.
This device has utilized the effect of current to safety check 3, through magnetic control element K
1And then by circuit water pump is controlled, have the advantage of precise control, and do not need installation accessories under water, install simple, applied widely.
