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, wherein a circuit board is arranged at the bottom of a sealed cavity in the pump body, two copper sheets are arranged on the circuit board in a staggering manner, one copper sheet is connected to the cathode of the direct current power supply while the other copper sheet is connected to the base of a triode, the collector and the emitter of the triode is connected between the cathode and the anode of the direct current power supply in series after being connected to the coil of a relay in series, a normally-closed contact of the relay is connected into the power supply line of the motor of the submersible pump in series, a resistor is connected between the node of the other copper sheet and the base of the triode and the cathode of the direct current power supply. According to the submersible pump provided by the invention, the copper sheets arranged at the bottom in the sealed cavity in the staggering manner are used for monitoring whether water enters, once water contacts the two copper sheets, a circuit is connected, the base of the triode switch is in a connected state at a high level, the coil the relay is connected, so that the normally closed contact to the power supply line of the motor in series is opened, and thereby the motor is in outage.
Description
Technical field
The present invention relates to a kind of immersible pump, belong to immersible pump technical field.
Background technology
The motor position of immersible pump is because need electricity consumption, thus the necessary cavity that forms a sealing, so that electric water is isolated.But immersible pump is positioned at underwater operation, therefore, it is unknown whether whether it leaked in annular seal space, and any leaks, and gently damages equipment, heavy cause water body charged, injury user of service.
Summary of the invention
The present invention wants technical solution problem to be: overcome the shortcoming of above-mentioned technology, the shortcoming of observing for immersible pump sealing state inconvenience, provides the one auto-breaking immersible pump that leaks.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: the one power-off immersible pump that leaks, comprises the pump housing and DC power supply; In the described pump housing, annular seal space bottom 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 relay coil, then be connected between the both positive and negative polarity of described DC power supply; The normally-closed contact of described relay is connected in series in described motor for submerged pump supply line, between the node of base stage of described another sheet copper sheet and triode and the negative pole of described DC power supply, is 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 power supply, is also in series with electric capacity.
Such scheme further improves and is, described DC power supply is 9V battery.
Whether utilization of the present invention is arranged in the staggered copper sheet of annular seal space inner bottom part and monitors and intake, natural water all has impurity, therefore there is certain conductivity, once have two copper sheets of water contact, connect circuit, triode switch ground level high level, in conducting state, relay coil is connected, thereby the normally-closed contact being connected in motor supply line is opened, and makes motor power-off.
Brief description of the drawings
Be described further of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the immersible pump structural representation of a preferred embodiment of the present invention.
Fig. 2 is the power-down circuit structural representation that leaks 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-immersible pump, 2-annular seal space, 3-impeller cavity, 4-water inlet, 5-delivery port, 6-power lug, K1-switch.
Embodiment
Embodiment
What the present embodiment provided leak power-off immersible pump, as shown in Figure 1, annular seal space 2 bottoms of immersible pump 1 are provided with circuit board as shown in Figure 3, staggeredly on circuit board are provided with two copper sheets and form a K switch 1.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 relay coil, then be connected between the both positive and negative polarity of DC power supply; The normally-closed contact of relay is connected in series in motor for submerged pump supply line, between the node of base stage of another sheet copper sheet and triode and the negative pole of DC power supply, is 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 by sealing ring.
In order to prevent relay coil 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, once there be water to be overlapped on two copper sheets by circuit turn-on, divider resistance resistance is got 1 megaohm to 2 megaohm, share most of voltage by divider resistance, this voltage drives triode switch conducting, also makes relay adhesive, the normally-closed contact of relay departs from power-off, thus the safety after guarantee is leaked.
When work, immersible pump 1 by its bottom water inlet 4 by water intake impeller chamber 3, after vane rotary is exerted pressure, by delivery port 5 connecting tubes, deliver to user place, the top of immersible pump 1 is provided with power lug 6, facilitates drawing of electric wire for motor, circuit board electric wire.
Circuit in the present embodiment in off state, only has triode power consumption slightly under normal condition, because triode is in cut-off state, the electric weight of its consumption also can be ignored, and a joint 9V battery can standby exceed 1 year.
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 range of requirement of the present invention.
