Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model is with respect to prior art, and is simple in structure, and cost is low.It adopts electrode and relay that liquid level is detected automatically, controls automatically, reports to the police automatically.
Embodiment:
As shown in Figure 1, the electric pole type fluid level controller in this example comprises transformer TM, first relay, second relay, the 3rd relay, electrode a, electrode b, electrode c, electrode d, electrode e, fan, hummer and bulb; Electrode a, electrode b, electrode c arrange to low from height; Electrode b connects the coil 1 of first relay by transformer TM; The coil 1 of first relay is by normally opened contact switch 5 connection electrode c; Another normally opened contact switch 4 of first relay is connected between live wire N and the zero line L by the coil 2 of second relay; A normally opened contact switch 6 of second relay is connected between live wire N and the zero line L by motor 7; The horizontal level of electrode d, electrode e is higher than electrode a, and electrode d connects the coil 3 of the 3rd relay by transformer TM, and electrode e connects the coil 3 of the 3rd relay; A normally opened contact switch 8 of the 3rd relay is connected between live wire N and the zero line L by hummer 9; Another normally opened contact switch 10 of the 3rd relay is connected between live wire N and the zero line L by bulb 11, and fan 12 directly is connected between live wire N and the zero line L.
Its principle of work is: transformer TM changes the 220V alternating voltage into the 24V alternating voltage, with as security control voltage.When liquid level in the groove was higher than electrode b height of living in, electrode b, electrode c were by the liquid conducting; If liquid level continue to rise arrives or when surpassing electrode a height of living in, electrode a, electrode b are by the liquid conducting, the coil 1 of first relay gets electronic work, normally opened contact switch 5 closures of first relay, normally opened contact switch 4 closures of while first relay, the coil 2 of second relay gets electronic work, normally opened contact switch 6 closures of second relay then, motor 7 gets electric startup and keeps running, drives submerged pump liquid in the groove is transported to liquid storage tank.When liquid level in the groove drops to when being lower than electrode a height of living in, electrode a was disconnected with being connected of electrode b, but because electrode b and electrode c still are in by the liquid conducting, and the normally opened contact switch 5 of first relay remains closed, so motor 6 remains in operation and drives submerged pump and continues liquid in the delivery chute.When liquid level in the groove drops to when being lower than b electrode height of living in, electrode b was disconnected with being connected just of electrode c, and motor 6 shuts down, and enters readiness.When liquid level in the groove reached electrode a height of living in once more, motor 6 started again, and work so moves in circles.
Cause in the groove liquid to overflow for the damage that prevents electric equipments such as motor 6, submerged pump or the control of operative employee's mistake and cause the environmental protection accident, utilize same principle also to be provided with electrode d, electrode e, their residing height will be higher than electrode a, when liquid in the groove arrives electrode d, electrode e height of living in and when being about to overflow, electrode d, electrode e conducting, the coil 3 of the 3rd relay gets electronic work, drive the normally opened contact switch 8 of the 3rd relay, normally opened contact switch 10 closures of the 3rd relay simultaneously, bulb 11 glows, hummer 9 begins the sounding of reporting to the police.Because transformer TM wants long-term charging operation, heating easily, because the too high damage coil insulation of temperature causes turn-to-turn short circuit, we have also designed a fan 12 on voltage device next door it have been carried out the forced draft cooling in order to avoid it.
Because the coil control circuit of first relay, the 3rd relay will come conducting with liquid, need to consider the operating current and the holding current of its coil.With liquid is that phosphoric acid is example, the resistance of the phosphoric acid of 41%46% concentration is between 65 ohm to 95 ohm, therefore just should to select model for use be the relay of AC24V for the HH54P coil voltage for first relay and the 3rd relay, its AC impedance is big, operating current and holding current are little, and coil is not easy heating.If select other model relay for use, may be because AC impedance be little, the cause that adhesive and holding current are big causes coil heating to damage.The material of electrode should be selected the strong stainless steel material of corrosion resistance for use.
The foregoing description only illustrates for one in the utility model, and those skilled in the art is easy to describe slightly according to it, and do change reaches same technique effect, and it all belongs to protection domain of the present utility model.
