Description

TECHNICAL FIELD

[0002] Reservoir ice prevention in an alpine region is a key task to ensure safe operation of a reservoir in winter, water resource scheduling and stability of a surrounding ecological environment, and a reservoir gate is a key facility for controlling water flow and regulating a reservoir water level, and ice formation in winter may cause the reservoir gate to be stuck, fail to open and close, and even be damaged due to excessive ice pressure, thereby seriously threatening safe operation of the reservoir, and therefore, the reservoir gate needs to be prevented from icing.

[0003] Currently, a commonly used reservoir ice prevention technology in engineering is active ice prevention (preventing ice formation), and the most common way in active ice prevention is a bubble ice prevention system, which releases a large number of small bubbles into water through an underwater bubble generator, and the bubbles drive water to circulate up and down in the process of rising, transport warm water in the bottom layer to the surface layer, break the inverse temperature layer, and maintain the surface water temperature above the freezing point; at the same time, bubble disturbance can prevent ice nuclei from forming and inhibit ice layer growth.
