Constant-flow automatic ecological discharge method and constant-flow automatic ecological discharge device
The invention discloses a constant-flow automatic ecological discharge method and constant-flow automatic ecological discharge device, and belongs to the technical field of water conservancy projects. The constant-flow automatic ecological discharge method comprises the following contents: A, acquiring the average minimum discharge water head difference deltaH, which is used for maintaining the requirement of the ecological environment of a reach under the current climate, of the reach; B, acquiring the actual water level H1 of an upstream reach and the water level H2 of an overflowing hole for discharge on a gate in real time, wherein the overflowing hole is formed in the gate, and the height of the overflowing hole is adjustable; C, judging whether actual discharge water head difference (H1-H2) is equal to the average minimum discharge water head difference deltaH, if yes, not adjusting the height of the overflowing hole, and if not, adjusting the height of the overflowing hole to enable H1-H2 to be equal to deltaH so as to meet the minimum ecological discharge amount requirement under the current climate. The position of the overflowing hole for discharge on the gate is automatically regulated according to an upstream water level in real time to realize constant-flow automatic ecological discharge, and a novel method is provided for solving the downstream ecological environmental protection problem of the downstream.
