Bubble anti-freezing system for reservoir dam in cold region
The invention provides a bubble anti-freezing system for a reservoir dam in a cold region, and belongs to the technical field of reservoir dam anti-freezing. The bubble anti-freezing system for the reservoir dam in the cold region involves a bubble device, a floating body and an air supplying device, wherein the bubble device is arranged underwater and attached to the slope surface of the reservoir dam; the floating body floats on the water surface of a reservoir and is connected with the bubble device; and the air supplying device is used for supplying air to the bubble device to enable the bubble device to generate bubbles flowing towards the water surface of the reservoir. The bubbles move from bottom to top to carry heat of a thermotropic water body on the lower portion of the reservoir to the water surface of the reservoir to prevent water bodies around the upstream side (slope) of the reservoir dam from being frozen; in addition, the system can automatically adjust the position of the bubble device along with rising (or falling) of the water level of the reservoir; a temperature threshold value is set, so that the system automatically starts, adjusts and stops the air supplying device to supply air to the bubble device; and the anti-freezing mode cannot damage the dam body structure, can effectively prolong the service life of a dam body, ensures the safe operation of thereservoir, and can be widely applied to anti-freezing protection of the reservoir dam in the cold region.
本申请提供了一种寒区水库大坝气泡防冻系统，属于水库大坝防冻技术领域。寒区水库大坝气泡防冻系统包括气泡装置、漂浮体和供气装置。气泡装置布置于水下并贴靠于水库大坝的坡面。漂浮体漂浮于库水面上并与气泡装置连接。供气装置用于为气泡装置供气，以使气泡装置产生向库水面流动的气泡。气泡从下向上运动将水库下部正温水体热量携带至库水面，来防止水库大坝迎水侧(坡面)周围水体的冻结。此外，该系统能够随库水位的升高(或降低)自动调节气泡装置的位置。通过设定温度阈值，系统自动开启‑调节‑停止供气装置为气泡装置供气。这种防冻形式不会破坏坝体结构，可有效延长坝体使用寿命，保障水库安全运营，可以广泛地应用于寒区水库大坝的防冻保护中。
