Abstract
The utility model relates to a water resistance detecting controlled full-automatic water supplying device, which belongs to the device for automatic detecting position control water pump switches. The water resistance detecting controlled full-automatic water supplying device comprises a signal detection circuit (1), a radiating dipole bistability detection circuit (2), a relay driving loop (3) and a power circuit (4). When the water level rises to an upper water level electrode, and contacts with the upper water level electrode, the input resistance of the radiating dipole input end gets small, and the radiating dipole bistability turns over to export high potential to switch off the power of a complementary dynatron, a relay and a contactor in order to cause to switch off the power of the water pump to stop pumping water. When the water in the water tower descends to a lower water level detection electrode, and does not contact with the lower water level detection electrode, the BG3 exports high potential because the water resistance is increased. The BG2 exports low potential to cause the relay and the contactor to obtain power to pump water. The automatic detection of the water level is realized, and the control of the switch of the water pump is realized. The water resistance detecting controlled full-automatic water supplying device has the advantages of simple structure, low cost and high reliability.
