Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 1, Fig. 2 and shown in Figure 3, the automatic control device of safe water of the present utility model comprise be installed on the water pipe be used for the circulation of control water pipe or the electromagnetic water valve 1 of closing, for detection of the sensor that has non-water flow to pass through in the water pipe, flowing water control circuit of time limit 2, for detection of the probe that has or not ponding on the ground and excess surface water control circuit 3; Described sensor is located at outlet pipe 1.1 places of described electromagnetic water valve 1, and described sensor is connected with described flowing water control circuit of time limit 2; Described probe is located on the ground of easy ponding, and described probe is connected with described excess surface water control circuit 3.
Described sensor comprises spring sheet 4, magnet 5 and hall sensor 6; Described spring sheet 4 is located at outlet pipe 1.1 places of described electromagnetic water valve 1; Described magnet 5 is located on the end of described spring sheet 4; Described hall sensor 6 is located at outside the outlet pipe 1.1 of described electromagnetic water valve 1, described magnet 5 be positioned at described hall sensor 6 under and the magnet S utmost point over against hall sensor, this hall sensor 6 is connected with described flowing water control circuit of time limit 2.
Described probe comprises the first wire A and the second exposed wire B of an end that an end is exposed; The other end of the other end of described the first wire A and the second wire B all is connected on the described excess surface water control circuit 3.Each long 2CM of the exposed part of described the first wire and the second wire, these two wires are fixed on the ground of easy ponding, and are parallel to each other interval 3mm.
Described electromagnetic water valve, the moving iron core in the no electric circuit at ordinary times, valve rests on valve body top under three spring actions, and sealing plug is and then upwards mentioned, and current are unimpeded.Only have when pipeline and leak or during water waste, the normally opened contact of flowing water control circuit of time limit is closed, the solenoid valve energising, electromagnetic coil makes iron core and static iron core adhesive, and sealing plug clogs valve pass water under the promotion of moving iron core.This at ordinary times not power consumption of electromagnetic water valve open in usual can be described as zero energy consumption, energy-conserving and environment-protective, and also when accidental generation had a power failure, user's water can not be affected.
The automatic control device of this specific embodiment safe water, power supply are selected WH0812 power conversion module, and it can directly become the 12V VDC with the 220V AC voltage conversion, for current control circuit of time limit and the electricity consumption of excess surface water control circuit.Not only volume is little for this power conversion module, and is lightweight, durable in use, and can improve the reliability of circuit working.
When the normal water of user, solenoid valve is opening state, this moment is because water tap pass water is timely, stop during stream during water in the pipeline, the signal that hall sensor is transferred to the flowing water control circuit of time limit is also changing every now and then, and therefore the time of every section lasting flowing water is all within the time limit that the flowing water control circuit of time limit arranges, control chip in the flowing water control circuit of time limit is exported high level all the time, the VT1 cut-off, electromagnetic water valve can not closed without electricity, makes current logical.And leak or during water waste, flowing water is successive in the water pipe when water pipe, the sensor reed of being hit by a bullet can not reset under the promotion of water, the magnet displacement exceeds the time limit, and the time of Hall transducer output high level also exceeds the time limit, the control chip output low level, the VT1 conducting, water is closed in the electromagnetic water valve energising.
If the user in the situation of normal water, has also exceeded the time limit that arranges, water supply stops, and the user can click trigger button (lockage button in the circuit, S1, S2) at control panel, makes capacitor C 1, and C2 voltage descends rapidly, control chip output high level.The VT1 cut-off, relay resets, electromagnetic water valve outage water flowing.Meanwhile the user can increase at control panel adjusted knob and set the time limit as required, so just can avoid the phenomenon of cutting off the water in the normal water situation.
The first wire and the second wire exposed part immersion of when excess surface water, popping one's head in, the first wire and the second wire conducting, triode VT2 conducting, control chip output high level, the electromagnetic water valve energising is closed valve and is cut off the water supply.Treat that ground is anhydrous, the first wire and the second wire break, electromagnetic water valve can discharge water by automatic valve opening again.During test circuit, press the button S3, this is equivalent to the situation of excess surface water, the first wire and the second wire conducting, and triode VT2 conducting, the control chip output high level of excess surface water control circuit, relay, electromagnetic water valve are worked in succession, bar up the water source; It is anhydrous that the relieving button is equivalent to ground, the first wire and the second wire break, triode VT2 cut-off, capacitor charging (effect of electric capacity is to postpone discharge time), the control chip output low level of excess surface water control circuit, relay, electromagnetic water valve discharge water without reset.
