The invention relates to water level elevation self-control full-automatic water pumping equipment. The water level elevation self-control full-automatic water pumping equipment comprises a control box placed on the ground. The control box is close to a well mouth of a water well. A water pumping device and a water level monitoring device are connected to the control box. The water pumping devicecomprises a drain pipe extending into the water well, and a water pump is fixedly arranged at the bottom of the drain pipe. The water level monitoring device comprises a heavy hammer limiting switch arranged at the top of the water well, a measuring rope is connected to the bottom of the heavy hammer limiting switch, and a balancing weight capable of floating on the water surface is arranged at the bottom of the measuring rope. An automatic water pumping circuit for controlling the water pump to work by pushing the balancing weight to control on and off of the heavy hammer limiting switch through buoyancy of water in
