Idling alarming submersible pump

一种空转报警潜水泵

Abstract

本发明涉及一种潜水泵,属于潜水泵技术领域。该潜水泵包括泵体和直流电源;所述泵体的叶轮腔内设有电路板,所述电路板上交错设有两片铜皮;所述一片铜皮连接所述直流电源正极;所述另一片铜皮与一个三极管的基极连接;所述三极管的集电极和发射极与一个发光二极管串联后,再串联在所述直流电源的正负极之间;所述另一片铜皮与三极管的基极的节点与所述直流电源的负极之间串联有电阻。本发明利用布置在潜水泵的叶轮腔内的电路板来监测潜水泵目前能否吸取到水。有水接触两片铜皮,则接通电路,三极管开关处于导通状态,发光二极管即被点亮,从而提示目前水位正常,叶轮腔内有水,潜水泵可以正常吸取水。
The invention relates to a submersible pump, and belongs to the technical field of submersible pumps. The submersible pump comprises a pump body and a direct current power source, wherein a circuit board is arranged in an impeller cavity of the pump body, two copper sheets are arranged on the circuit board in a staggered mode, one copper sheet is connected with a positive electrode of the direct current power source, the other copper sheet is connected with a base electrode of an audion, a collector electrode and an emitting electrode of the audion are connected with a light-emitting diode in series and then connected between the positive electrode and a negative electrode of the direct current power source in series, a resistor is connected between the other copper sheet and a joint of the base electrode of the audion in series, and another resistor is connected between the copper sheet and the negative electrode of the direct current power source in series. According to the submersible pump, the circuit board in the impeller cavity of the submersible pump is used for monitoring whether the submersible pump can suck water at present. Water makes contact with the two copper sheets to enable a circuit to be powered on, an audion switch is on, the light-emitting diode is lightened on, and therefore it is indicated that the water level is normal at present, water exists in the impeller cavity, and the submersible pump can suck water normally.
