PURPOSE: A no-power automatic water gate system using a water weight and a lever is provided to open and shut a water gate automatically and to promote the convenience and eco-friendliness of a water gate by using a water weight and a lever without. CONSTITUTION: The no-power automatic water gate system using a water weight and a lever comprises a lever(1) which is in a seesaw motion and supported by a fixed shaft, a water gate(2) installed to one side of the lever(1), a water weight(3) installed on the other side of the lever(1), and an aqueduct(4) flowing the upper stream of a submerged weir into the water weight(3). If the water weight(3) comes up from the fixed shaft of the lever(1), a water gate(2) goes down, and if the water weight(3) goes down, the water gate(2) goes up.
