[description of drawings]
Fig. 1 is the automatic submersible pump structural representation of the utility model.
[embodiment]
See also shown in Figure 1ly, a kind of automatic submersible pump comprises water level monitoring circuit, control executive circuit and power converting circuit, and above-mentioned control executive circuit connects water level monitoring circuit and power converting circuit.Described water level monitoring circuit comprises high water level electrode A, low water level electrode B and main electrode C.Described control executive circuit comprises relay K 1, oxide-semiconductor control transistors V, A.C. contactor KM and diode D5.Described power converting circuit comprises supply convertor T, motor M, rectification circuit, filter capacitor C1, and above-mentioned rectification circuit comprises four commutation diode D1-D4.
The control executive circuit also comprises 1/4 fixed carbon resister R1, R2.The emitter of oxide-semiconductor control transistors V is connected with main electrode by resistance R 2; The base stage of oxide-semiconductor control transistors V directly is connected with main electrode; The collector electrode of oxide-semiconductor control transistors V is connected with high and low level electrode with resistance R 1 by relay K 1.The anode of diode D5 connects the collector electrode of oxide-semiconductor control transistors V, and its negative electrode is connected with rectification circuit.Relay K 1 is chosen 12V direct current double-contact relay.A.C. contactor KM chooses the 380V three-phase ac contactor.Commutation diode D1-D4 is the IN4007 silicon rectifier diode.
Too high in order to prevent the motor M temperature, and cause its damage, therefore a temperature controller T ' is set preferably and is connected with relay K 1.
Its working principle of the automatic submersible pump of the utility model is as follows: threephase AC is after power transformer T coupling, through four commutation diode D1-D4 rectification, become the 12V direct current after the filter capacitor C1 filtering again through resistance R 1 to high water level electrode A, add to the base stage of oxide-semiconductor control transistors V then through the conductive resistance of water and main electrode C, make the positively biased conducting of base stage of oxide-semiconductor control transistors V, relay K 1 work, K1-1, K1-2 normally opened contact closure, A.C. contactor KM work, therefore submersible pump begins to draw water, water level slowly descends, when water level is lower than low water level electrode B point, owing to low water level electrode B exposing of ordering makes not conducting between low water level electrode B point and the main electrode C, the base stage of oxide-semiconductor control transistors V does not have current potential and makes oxide-semiconductor control transistors V not work, relay K 1 work, K1-1, the K1-2 normally opened contact is because of no magnetic force adhesive tripping.Submersible pump stops pumping.When water level slowly rises, by low water level electrode B point to high water level electrode A, submersible pump such as the above-mentioned work that goes round and begins again.
The utility model has been introduced a kind of automatic submersible pump by being example with water level monitoring circuit, control executive circuit and temperature controller, and this can not be considered to the restriction to the utility model claim.If those skilled in the art has made change unsubstantiality, conspicuous or improvement according to the utility model, all should belong to the scope of the utility model claim protection.
