Description
Technical field
The utility model relates to a kind of water pump, especially relates to the brushless starting mode of pump circuit of a kind of solar energy.
Background technology
Existing solar energy view pump is provided with solar panels and water pump, because the power of solar panels has very big relation with the light of environment, the input power of ambient light is in the continuous variation, power when particularly just come out morning on the solar panels is in the process of constantly strengthening, brushless starting mode of pump needs a bigger starting power, but the power of solar panels is owing to can't provide bigger starting power in constantly changing, cause water pump to have a bigger electric current to flow through all the time, and water pump can't start, water pump must could start after solar panels reach a bigger power like this, and before starting, water pump has electric current to flow through all the time, causes water pump to damage easily.
Summary of the invention
The purpose of this utility model is to provide a kind of solar energy brushless starting mode of pump circuit.
The utility model is provided with solar panels, storage capacitor, the voltage acquisition bleeder circuit, single-chip microcomputer, dummy load, dummy load switch control valve, the pump switch control valve, voltage detecting circuit and voltage stabilizing circuit, the output of solar panels connects storage capacitor respectively, voltage acquisition bleeder circuit and voltage stabilizing circuit, storage capacitor connects dummy load and water pump respectively, voltage acquisition bleeder circuit and voltage detecting circuit output connect the single-chip microcomputer input interface respectively, dummy load switch control valve and pump switch control valve input connect the single-chip microcomputer output interface respectively, dummy load switch control valve connects dummy load, the outer water pump of pump switch control valve, output end of stabilized voltage supply connects single-chip microcomputer and voltage detecting circuit respectively.
Dummy load (dummy load also claims load resistance) is used to test the power of solar panels at that time and the power resistor set.
Because the utility model adds storage capacitor at the solar panels two ends, and not direct water pump, when the internal resistance of solar panels is bigger,, and then connect water pump to the storage capacitor charging, water pump obtains the big electric current of short time, just can start, after the startup, solar panels just can be kept the running of water pump with less power, thereby reach the purpose that starts water pump ahead of time, allow pump operation.
In addition; the utility model the time does not allow the electric current of the solar panels water pump of flowing through in beginning; but allow the power of the present solar panels of electric circuit inspection; when the power that detects solar panels reaches the minimum running power that can keep water pump; allow electrochemical capacitor pass through solar panel charging earlier; storage starts necessary energy; connect water pump then; just can allow starting mode of pump keep on the go then; in pump operation, detect the voltage of water pump solar panels; when solar panels voltage can't be supported the running of water pump, block the water pump power supply, thereby play the purpose of protection water pump.
