Water delivery open channel turbulent-flow-making anti-freezing method

The method is characterized in that the temperature of water flow in the open channel is detected in real time, and when the temperature of the water flow is reduced to be close to the icing temperature, a turbulence control motor is started to drive an impeller with the lower portion located below the water surface to rotate, water is forcibly stirred to make turbulence, and the water is prevented from being frozen. Water flow energy can be collected when the water temperature is high, turbulent fluctuation is generated when the water temperature is low, freezing prevention is achieved, the situation that the water conveying efficiency is reduced due to water freezing is avoided, and the stability and reliability of water flow conveying of a water conveying open channel can be better guaranteed. 本发明公开了一种输水明渠制紊防冻方法，其特征在于，实时检测明渠内水流温度，当水流温度降低至接近结冰温度时，启动制紊电机带动下部位于水面下方的叶轮转动，强制激荡水体制造紊动，防止水体冻结。本发明能够在水温较高时收集水流能量，并在水温较低时制造紊动实现防冻，避免因水体结冰而致使输水效率下降，可以更好地保证输水明渠对水流输送的稳定性和可靠性。
