Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1
Referring to accompanying drawing 1, the present embodiment is high area's water system of the residential building of 23 floor, including by water supply installation, automatically controlled dress
Put 3, floor water tank and its level sensor 4.09-4.23, elevated tank and its level sensor 4.24, with water tank is supporting enters
Water valve 5.09-5.24, the direct current hydrogenerator 6.09-6.23 concatenated with the water intaking valve 5.09-5.23 of each floor water tank, institute
The water supply installation stated can be the water pump or supercharging device using direct current generator 1, and described direct current generator 1 is separate excitation direct current
Machine, its power supply are included by civil power 2 after a/d converter 8 is changed, when controlled source 7 is connected to the first of armature winding power supply
Power supply, and to the second source of Exciting Windings for Transverse Differential Protection power supply, described electricity as caused by above-mentioned direct current hydrogenerator 6.09-6.23
The signal input part of control device 3 is connected with above-mentioned level sensor 4.09-4.24 output ends, when a certain water tank, for narration
It is 12 floor water tanks conveniently to assume the water tank, and when its water level is less than pre-determined lower limit water level, the output end of level sensor 4.12 is by height
Resistance state or intermediate level switch to low level, and electric control gear 3 makes the closure of controlled source switch 7, entered after the level change is detected
Water valve 5.12-5.24 is opened simultaneously, hydrogenerator 6.12-6.23 is rotated and generated electricity, so that the first power supply and second source are same
When to drive water supply installation direct current generator 1 power, start water supply process, when 12 floor cistern water levels are higher than pre-determined lower limit water level
When, the corresponding output end level of level sensor 4.12 switchs to high-impedance state or intermediate level by low level, and water supply continues, when
When 12 floor cistern water levels meet or exceed preset upper limit water level, the corresponding output end level of level sensor 4.12 is by high-impedance state
Or intermediate level switchs to low level, electric control gear 3 after the level change is detected, make controlled source switch 7 disconnect, and make into
Water valve 5.12-5.24 is closed, and causes hydrogenerator 6.12-6.23 to stop operating, the first power supply and second source stop simultaneously
Power supply, makes water supply installation be stopped.The present embodiment uses direct current hydrogenerator and DC motor Driver water supply installation, not only
Multichannel phase transition arrangement is eliminated, moreover, do not increase motor, thus, compared with prior art, have and significantly drop
Low equipment cost and make the more simplified advantageous effects of water system.
Embodiment 2
Referring to accompanying drawing 1, compared with Example 1, difference essentially consists in：Described electric control gear 3 is on cistern water level is higher than presetting
When restricting water supply, the water intaking valve of the water tank is simply turned off, i.e. the water intaking valve of water tank can be by electric control gear 3 in the water tank or lower water
Water level open when being less than pre-determined lower limit water level, but not because the high water preset upper limit water level of other cistern water levels is closed.Cause
This, if a certain water tank needs moisturizing, can not only fill the water tank, moreover, can also from bottom to top all water tanks are one by one on
Fill, therefore, floor cistern water level can be avoided to be higher than pre-determined lower limit water level, and elevated tank water level is less than pre-determined lower limit water level
Situation occurs.Elevated tank is avoided to need moisturizing, but hydrogenerator does not generate electricity, and the motor 1 of water supply installation can not start
Situation occur.
Embodiment 3
Referring to accompanying drawing 2, compared with embodiment 1,2, difference essentially consists in：Described direct current generator 1 employs shunt DC machine,
It is that direct current generator 1 is powered through controlled power switch 7, controlled source switch 7 is by high-order water after first power supply, second source parallel connection
The water intaking valve 5.24 of case controls, and water intaking valve 5.24, which is opened/closed, causes the on/off of controlled source switch 7.Due to separate excitation direct current
Machine needs dual power supply, so, the technical scheme of embodiment 1 can not exclude possibility out of control completely in theory, although pressing embodiment 2
Scheme when can need moisturizing with floor water tank in office, make the water tank and including elevated tank on all water tanks mend
Full water, and generally elevated tank is much larger than floor water tank, there is usually no floor water tank and is not required to moisturizing, and elevated tank needs
The possibility of moisturizing, still, many secondary water-supply conceptual design fire demand waters and domestic water share elevated tank now, at this moment
Floor cistern water level be present and be above lower limit water level, and elevated tank is because fire fighting needs are overused, water level less than setting in advance
Restrict water supply the possibility of position.Because shunt DC machine only needs single supply, the power supply of the present embodiment first and second source parallel operation, institute
With also will not be out of control even if there is the above situation.The present embodiment controlled source switch 7 is controlled by the water intaking valve 5.24 of elevated tank
System, deenergization, can avoid equipment from damaging when the water intaking valve breaks down.Remaining does not address part, same as Example 2.
It is pointed out that every equivalent transformation done using description of the invention and accompanying drawing content, or identical essence
The different expression of implication, and other related technical areas are directly or indirectly used in, in patent protection model of the invention
In enclosing.
