Abstract
The invention relates to a submerged pump, and belongs to the technical field of submerged pumps. A water level alarm submerged pump comprises a pump body and a direct-current power source. A circuit board is arranged on the top of the pump body. Two copper pieces are arranged on the circuit board in a staggered mode. One copper piece is connected with the positive electrode of the direct-current power source. The other copper piece is connected with a base electrode of a triode. A collector electrode and an emitting electrode of the triode are connected between the positive electrode and the negative electrode of the direct-current power source in series after being connected with a light-emitting diode in series. A resistor is connected between the node between the other copper piece and the base electrode of the triode and the negative electrode of the direct-current power source in series. According to the water level alarm submerged pump, the circuit board arranged on the top of the pump body is used for monitoring whether the water level is still higher than the pump body, a circuit is turned on when water makes contact with the two copper pieces, a base electrode of a triode switch is provided with a high electric level, the triode switch is in an on-state, the light-emitting diode is switched on, and therefore it is indicated that the current water level is higher than the pump body.
Description
Technical field
The present invention relates to a kind of submersible pump, belong to submersible pump technical field.
Background technology
Submersible pump need to completely sink in water and work, its motor radiating rely on shell and water contact realize.When water level deficiency is exposed the pump housing, the accident that may cause motor overheating to burn.
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, a kind of water level automatic alarm submersible pump is provided.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of water-level alarm submersible pump, comprises the pump housing and direct supply; Described pump housing top 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 direct supply; Between the node of base stage of described another sheet copper sheet and triode and the negative pole of described direct supply, 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 direct supply, is also in series with electric capacity.
Such scheme further improves and is, described direct supply is 9V battery.
Utilization of the present invention is arranged in the circuit board on submersible pump summit and whether monitors water level also higher than submersible pump, and natural water all has impurity, therefore has electric conductivity.There are two copper sheets of water contact, connect circuit, triode switch ground level high level, in conducting state, light emitting diode is lit, thereby prompting current water level is higher than submersible pump, and when water level is during lower than submersible pump, between two copper sheets, open circuit, triode switch cut-off, light emitting diode extinguishes, and indication current water level is lower than submersible pump.
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 inlet, 5-water delivering orifice, 6-power lug, K1-switch.
Embodiment
Embodiment
The water-level alarm submersible pump that the present embodiment provides, as shown in Figure 1, the pump housing 2 tops of submersible pump 1 are 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 direct supply; Between the node of base stage of another sheet copper sheet and triode and the negative pole of direct supply, be in series with divider resistance and filter capacitor.
The present embodiment adopts 9V battery as DC power supply.
Can arbitrarily change as required as the shape of Fig. 3 circuit board in the present embodiment, for cost-saving, make fritter and is placed in the pump housing 2 tops.
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, and capable of prompting water level is higher than the pump housing 2.Otherwise diode extinguishes, capable of prompting water level is lower than the pump housing 2.
During work, submersible pump 1 by its bottom water inlet 4 by water intake impeller chamber 3, after vane rotary is exerted pressure, by water delivering orifice 5 connecting tubes, deliver to user place, the top of submersible pump 1 is provided with power lug 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 condition, electric current is less than 5ma, maintains about 3ma, in theory a joint 9V battery can continuous working over 70 hours, for improving service time, can also replace with AC/DC change-over circuit.
The present invention is not limited to the concrete technical scheme of above-described embodiment, and all employings are equal to replaces the technical scheme forming, and is the protection domain of requirement of the present invention.
