Underground water exploitation apparatus manufacturing technology

An underground water exploitation apparatus manufacturing technology comprises a water level detector, a roller, a measuring band, a signal receiving unit and a water pump motor. The water level detector is fixed one end of the hollow measuring band winding the roller; the other end of the measuring band is connected with a wireless signal emitting module; a signal transmission line is placed in the hollow measuring band; the signal transmission line is connected with the water level detector and the wireless signal emitting module; the signal receiving unit is formed by a wireless receiving module, a one-chip microcomputer control module and a DC motor driving module; and the wireless receiving module, the one-chip microcomputer control module and the DC motor driving module are orderly connected with each other. During the use, the water pump motor can be opened or closed according to the signal detected by the water level detector, so water level changes during the exploitation can be effectively controlled; and effective solutions can be provided for underground water over exploitation.
