Abstract
The utility model relates to an automatic water supply monitor, which uses a 555 time base integrated circuit to control the operation of a water pump motor. The utility model automatically supplies water according to the height variation of water level, and solves the problem that water in a water storage device overflows or is insufficient. The utility model has the characteristics of simple and convenient operation, low cost and energy saving. The utility model can be used in fields of household living water storage, aquacultures, etc.
Description
The utility model relate to a kind of can be according to the automatic water-supply supervising device of water level height automatic water-supply.
Urban and rural residents provide the small-sized tap water facility for oneself and supply water, and what adopt at present is traditional with the manually-operated mode of plug-in strip, controls the operation of pump motor, realize supplying water or stop to supply water.The weak point of its existence is trivial operations, and water level control is difficult for grasping, or overflows or owe water.
It is a kind of according to the high low energy automatic water-supply of water level or stop the automatic water-supply supervising device to supply water automatically, both energy-conservation that its purpose of the utility model just is to provide, and operates simple and conveniently again, and solves the problem that water overflows or owe water.
The technical scheme that realizes above-mentioned purpose and take comprises by pump motor M, transformer B, and rectification circuit and control circuit are formed, and also comprise sensing element A, B, C and relay J
1, control circuit adopts 555 o'clock basis sets to become IC, 555 time base circuit IC the 2nd pin water receiving site B, and the 6th pin water receiving site A exports the 3rd pin and succeeds electrical equipment J
1Coil, its normally opened contact water pump motor M.
Below in conjunction with accompanying drawing this device is further described,
Accompanying drawing is this device electric control schematic diagram.
This device is by pump motor M
1Transformer B, rectification circuit and control circuit are formed, and also comprise sensing element A, B, C and relay J
1, control circuit adopts 555 o'clock basis sets to become IC, 555 time base circuit IC the 2nd pin water receiving site B, and the 6th pin water receiving site A exports the 3rd pin and succeeds electrical equipment J
1Coil, normally opened contact water pump motor M.
The principle of work of automatic water-supply watch-dog adopts the main element of time-base integrated circuit 555 as the center, because this element has low triggering end 2 pin, and high-triggering end 6 pin and reset terminal 4 pin, when water level is lower than the B point, time base circuit IC3 pin output high level, relay J
1The electric adhesive of coil, its normally opened contact closure, the pump motor M operation of switching on realizes supplying water.When water level is higher than the A point, 6 pin outer ring resistance R
4Drop-down, make the output of 3 pin become low level, relay J
1The disconnection that resets of coil losing electricity, its normally opened contact, Pump Failure stop to supply water, this moment 4 pin presets.Monitoring and so forth.
Because the fluctuation of line voltage, transformer B secondary voltage fluctuates with voltage ripple of power network, and time base circuit IC555 needs more specific voltage, therefore in prime for time base circuit, adopt 7812 three-terminal voltage-stabilizings, burning voltage make the main center part of this watch-dog be in steady operation in the best voltage range all the time, thereby the voltage of guaranteeing good sensitivity and super wide range also can operate as normal.
Compared with prior art this device has the following advantages:
Therefore because its control center part adopts 555 o'clock integrated IC of base, it is simple to have a control circuit, The characteristics that cost is low, and easy to operate, need not manually on duty.
