Background technique

Present known drainage system is all by control manually, observe the depth of water level and then need to judge whether draining by people's naked eyes, so not only lose time and also expend muscle power, especially when the people is tired out, be easy to produce erroneous judgement, easily cause danger, also can cause water to be drained the situation that water pump is still being worked because of people's carelessness of forgeing sometimes, also make the water pump dehydration because of the thing that goes out of use blocks bottom valve the working life that so not only influences motor, leaks gas and do not draw the proper functioning that water influences water pump.

The model utility content

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of accuracy of judgement is provided, and efficient is apparently higher than control manually, and is safer more reliable, and can be because of water pump does not have the malfunction of leaking on a small quantity, the self-draining arrangement of convenient again debugging and maintenance.

To achieve these goals, the technical solution of the utility model is a kind of self-draining arrangement, comprise that fluid level controller, safety check, water pump, bottom valve, control circuit, pump motor and electronic probe is characterized in that: the input end of fluid level controller is connected with the output terminal of electronic probe signal, first electronic probe is contained in upper limit position, second probe is contained in the position concordant with plane on the bottom valve, the 3rd probe is contained in the position concordant with the bottom valve lower end surface, and fluid level controller is electrically connected with pump motor by control circuit.

Self-draining arrangement, described water pump pipeline output terminal is provided with a safety check that has one gap, and with the water pump pipeline scyewed joint, a bottom valve then be housed and also be to be threaded at the water pump pipeline input end with water pump pipeline.

Self-draining arrangement, the signal that first electronic probe elicites directly is connected with the input end of fluid level controller by circuit, the signal of second electronic probe is connected with the input end of fluid level controller through a stop button, the signal that the 3rd electronic probe elicites then directly is connected with the input end of fluid level controller by circuit, and lead connection centre is arranged between first electronic probe and the 3rd electronic probe and be provided with a start button.

Self-draining arrangement, control circuit comprise first relay and second relay, and first relay is connected with the output terminal of fluid level controller, and the output terminal of second relay and fluid level controller connects connection.

Self-draining arrangement also comprises thermorelay and protective relay and is electrically connected with pump motor in the control circuit.

Self-draining arrangement; owing to adopt said structure; control water level accurately; working efficiency is apparently higher than control manually; and it is safe and reliable; and the utility model is connected to thermorelay can disconnects the safety of motor power protection motor and circuit when the super stream of water pump, and is provided with the debugging of debug switch convenient for maintaining.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail

As shown in Figure 1, a kind of self-draining arrangement, comprise fluid level controller 1, safety check 2, water pump 3, pump motor 16, bottom valve 4, first electronic probe 5, second electronic probe 6, the 3rd electronic probe 7, control circuit 15 is characterized in that: the input end of fluid level controller 1 is connected with the signal output part of electronic probe, and wherein first electronic probe 5 is contained in upper limit position, second electronic probe 6 be contained in bottom valve 4 on concordant position, plane, the 3rd electronic probe 7 is contained in and concordant position, bottom valve 4 lower end surfaces, and the signal that first electronic probe 5 elicites directly is connected with the input end Y5 of fluid level controller 1 by circuit, and the signal of second electronic probe 6 is connected with the input end Y6 of fluid level controller through a stop button, the signal that the 3rd electronic probe 7 elicites then directly is connected with the input end Y7 of fluid level controller by circuit, and lead connection centre is arranged between first electronic probe 5 and the 3rd electronic probe 6 and be provided with a start button 14.Fluid level controller 1 is connected with pump motor 16 by control circuit 15.Wherein control circuit 15 comprises that also first relay 8 and second relay, 9, the first relays 8 are connected with the output terminal Y3 of fluid level controller, and the output terminal Y2 of second relay 9 and fluid level controller 1 is connected.

Like this when water level rises to upper limit position, first electronic probe 5 disconnects the normally open contact that the signal that elicites passes to the input end Y5 fluid level controller 1 this moment of fluid level controller 1, first relay 8 discharges, the 9 normally closed interlock conductings of second relay, induction switch 12 adhesive water pumps 3 are started working, when water level is reduced to the position concordant with plane on the bottom valve 4, second probe 6 also passes to the signal that elicites in the fluid level controller 1, fluid level controller 1 normally opened contact conducting this moment, first relay, 8 adhesives, second relay 9 disconnects, induction switch 12 discharges water pump 3 and quits work, and bottom valve 4 just can not surface forever like this.
