Description
Technical field
The utility model belongs to a kind of water system.
Background technology
At present, use water pump to fetch water in some rural areas, water is stored in water tank or the water tower, when the water in water tank or the water tower was used up, the feed pump energising was again with water tank or water pump fills with water.When needs were used hand, if the water of storing has been used up, also need wait for a period of time got to water in water tank or the water tower water pump again, and when fetching water, all was the feed pump energising of manually operating a switch usually, existed certain dangerous.
The utility model content
A purpose of the present utility model is to provide a kind of auto-watering system, when can the water level in water tank being lower than certain altitude, makes the water pump energising automatically, with the water tank fills with water.
For achieving the above object, auto-watering of the present utility model system comprises water tank, water pump and switch board, and described water tank is provided with water inlet pipe, outlet pipe and leak-off pipe, is provided with control circuit in described switch board; In described water tank, be provided with high water level sensor and low water level sensor, described sensor is electrically connected with described control circuit, the pump working power supply passes through line breaker, contactor links to each other with pump motor with thermal relay, one circuitry phase of described working power links to each other with current rectifying and wave filtering circuit with transformer, one end of described two sensors links to each other with an end of rectification filter circuit output end, the other end of described high water level sensor connects an end of solid-state relay SSR1 input, the other end of described solid-state relay SSR1 input links to each other with the other end of described rectification filter circuit output end, the other end of described low water level sensor connects an end of solid-state relay SSR2 input, the other end of described solid-state relay SSR2 input links to each other with the other end of described rectification filter circuit output end, an output of described transformer connects an end of two described solid-state relay outputs respectively, one end of auxiliary reclay KA1 output, the other end of described solid-state relay SSR1 output links to each other with an end of auxiliary reclay KA1 input, the other end of described solid-state relay SSR2 output links to each other with an end of auxiliary reclay KA2 input, the other end of described auxiliary reclay KA1 output links to each other with an end of described contactor input, and the other end of the input of described auxiliary reclay KA1 and KA2 links to each other with another output of described transformer with the other end of described contactor input.
When water level was lower than contact B2, water pump was connected power supply automatically, fetched water in water tank.When water level reaches contact B2, the automatic disconnection pump power, water pump quits work.
The beneficial effects of the utility model are: safety improves greatly, and simple to operation.
Description of drawings
Fig. 1 is the schematic diagram of the system of fetching water described in the utility model.
Fig. 2 is the circuit theory diagrams of the system of fetching water described in the utility model.
The specific embodiment
Fig. 1 is the schematic diagram of the system of fetching water described in the utility model, and with reference to Fig. 1, the system of fetching water of the present utility model comprises water tank 1, water pump and switch board 2, and described water tank is provided with water inlet pipe 3, outlet pipe 4 and leak-off pipe 5; In described water tank, be provided with high water level sensor and low water level sensor, wherein contact B1 and B2 constitute high water level sensor, contact B1 and B3 constitute low water level sensor, are provided with control circuit in described switch board, and described sensor is electrically connected with described control circuit.
Fig. 2 is the circuit theory diagrams of the system of fetching water described in the utility model, with reference to Fig. 2, the pump working power supply is by circuit breaker Q F, contactor KM links to each other with pump motor M with thermal relay FR, one circuitry phase of described working power links to each other with current rectifying and wave filtering circuit with transformer, described contact B1 end links to each other with an end of rectification filter circuit output end, described B2 end connects an end of solid-state relay SSR1 input, the other end of described solid-state relay SSR1 input links to each other with the other end of described rectification filter circuit output end, described B3 end connects an end of solid-state relay SSR2 input, the other end of described solid-state relay SSR2 input links to each other with the other end of described rectification filter circuit output end, an output of described transformer connects an end of two described solid-state relay SSR1 and SSR2 output respectively, one end of auxiliary reclay KA1 output, the other end of described solid-state relay SSR1 output links to each other with an end of auxiliary reclay KA1 input, the other end of described solid-state relay SSR2 output links to each other with an end of auxiliary reclay KA2 input, the other end of described auxiliary reclay KA1 output links to each other with an end of described contactor input, and the other end of the other end of the input of described auxiliary reclay KA1 and KA2 and described contactor KM input links to each other with another output of described transformer.
When water level is lower than B1 and B2 and forms the high water level sense switch, between this moment B1 and the B2 owing to drawdown disconnects, solid-state relay SSR1 outage, switch S SR1 disconnects, thereby causes the constant open contact disconnection of auxiliary reclay KA1, constant close contact closure.And B1 and B3 are below water level, be in channel status, so solid-state relay SSR2 is in "on" position always, make auxiliary reclay KA2 be in closure state always, the constant open contact closure of KA2, thus make contactor KM closure, connect the power supply of water pump, water pump is started working, and fetches water in water tank.
When water level reaches contact B2, conducting between B1 and the B2 at this moment, solid-state relay SSR1 energising, the constant close contact of auxiliary reclay KA1 disconnects.This moment, contactor KM disconnected, and disconnected the power supply of water pump, and water pump quits work.
FU1 and FU2 are fuse, and control circuit is had protective effect.SA1 is a revolution switch, can carry out manual operation to water pump.
