Abstract
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 supply. A circuit board is arranged at the water inlet of the pump body, and two copper sheets are arranged on the circuit board in a staggered mode. One copper sheet is connected with the positive electrode of the direct-current power supply, and the other copper sheet is connected with the base of an audion. The collector and the emitter of the audion are connected between the positive electrode and the negative electrode of the direct-current power supply in series after being connected with a light-emitting diode in series. A resistor is connected between the node of the other copper sheet and the base of the audion and the negative electrode of the direct-current power supply. According to the submersible pump, the circuit board arranged at the water inlet of the submersible pump monitors whether the submersible pump can suck water currently; if water makes contact with the two copper sheets, a circuit is switched on, an audion switch is in the on-state, the light-emitting diode is lightened, and then it is reminded that the current water level is normal and the submersible pump can suck the water normally.
Description
Technical field
The present invention relates to a kind of submersible pump, belong to submersible pump technical field.
Background technique
Submersible pump need to completely sink in water and work.Especially home-use submersible pump, is placed in well and uses.The position of placing due to submersible pump is not easy to observe very much, is therefore difficult to learn water level situation.Once water level is too low, water pump can not be drawn to water, will make motor idle running.Motor idle running can make motor overheating, possible motor damage.
Summary of the invention
The present invention wants technical solution problem to be: overcome the shortcoming of above-mentioned technology, for the water position status of submersible pump present position, observe inconvenience, provide a kind of water level too low, submersible pump with automatic alarming when submersible pump can not be drawn.
In order to solve the problems of the technologies described above, the technological scheme that the present invention proposes is: a kind of Water free alarming submersible pump, comprises the pump housing and DC electrical source; The water inlet of the described pump housing is provided with circuit board, on described circuit board, interlocks and is provided with two copper sheets; Described a slice copper sheet connects described DC power anode; Described another sheet copper sheet is connected with the base stage of a triode; After the collector and emitter of described triode is connected with a light emitting diode, then be connected between the both positive and negative polarity of described DC electrical source; Between the node of base stage of described another sheet copper sheet and triode and the negative pole of described DC electrical source, be in series with resistance.
Such scheme further improves and is, between the node of base stage of described another sheet copper sheet and triode and the negative pole of described DC electrical source, is also in series with electric capacity.
Such scheme further improves and is, described DC electrical source is 9V battery.
Can the circuit board that utilization of the present invention is arranged in the water inlet of submersible pump be monitored submersible pump and be drawn to water at present.Natural water all has impurity, therefore has electric conductivity, once there be two copper sheets of water contact, connect circuit, triode switch ground level high level, on state, light emitting diode is lit, thereby prompting current water level is normal, and submersible pump can normally be drawn water, and when water level is too low, between two copper sheets, open circuit, triode switch cut-off, light emitting diode extinguishes, indication current water level is lower than the water intake of submersible pump, and submersible pump can not be drawn to water again.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, to of the present invention, be described further.
Fig. 1 is the submersible pump structural representation of a preferred embodiment of the present invention.
Fig. 2 is the warning circuit structural representation of the present embodiment.
Fig. 3 is K switch 1 board structure of circuit schematic diagram in Fig. 2.
Number in the figure is schematically as follows: 1-submersible pump, the 2-pump housing, 3-impeller cavity, 4-water intake, 5-water outlet, 6-wire terminal, K1-switch.
Embodiment
Embodiment
The Water free alarming submersible pump that the present embodiment provides, as shown in Figure 1, the inwall of the water intake 4 of the pump housing 2 is provided with circuit board as shown in Figure 3, the staggered K switch 1 of two copper sheets formation that is provided with on circuit board.As shown in Figure 2, wherein a slice copper sheet connects DC power anode; Another sheet copper sheet is connected with the base stage of a triode; After the collector and emitter of triode is connected with a light emitting diode, then be connected between the both positive and negative polarity of DC electrical source; Between the node of base stage of another sheet copper sheet and triode and the negative pole of DC electrical source, be in series with divider resistance and filter capacitor.
Due to this DC electrical source contact water body, so the present embodiment adopts 9V battery as DC power supply, to guarantee that water body can be not charged.
Can arbitrarily change as required as the shape of Fig. 3 circuit board in the present embodiment, for cost-saving, make fritter and settles on water intake 4 inwalls.
In order to prevent light emitting diode damage, in the circuit pathways at its place, be also installed with current-limiting resistance.
Two copper sheets on circuit board form the effect of K switch 1, after being connected on circuit, water is by two copper sheet conductings, divider resistance resistance is got 1 megaohm to 2 megaohm, by divider resistance, share most of voltage, this voltage drives triode switch conducting, also makes circuit of LED conducting, light emitting diode starts luminous, points out in current impeller cavity 3 and has water.Otherwise diode extinguishes, in prompting impeller cavity 3, there is no water.
During work, submersible pump 1 by its bottom water intake 4 by water intake impeller chamber 3, after vane rotary is exerted pressure, by water outlet 5 connecting tubes, deliver to user place, the top of submersible pump 1 is provided with wire terminal 6, facilitates drawing of electric wire for motor, circuit board electric wire.
Circuit in the present embodiment only needs position light emitting diode power consumption under normal state, electric current is less than 5ma, maintains about 3ma, in theory a joint 9V battery can continuous operation over 70 hours, for improving service time, can also replace with AC/DC change-over circuit; Must use insulating power supply.
The present invention is not limited to the concrete technological scheme of above-described embodiment, and all employings are equal to replaces the technological scheme forming, and is the protection domain of requirement of the present invention.
