Description

Technical Field

[0001] The utility model relates to the technical field related to anti-icing devices, in particular to an anti-icing device for a reservoir hub. Background Art

[0002] Reservoirs are a special type of lake resource used to store water, prevent floods, and generate electricity. At present, my country is vigorously developing new energy industries and planning a large number of pumped storage power stations in cold regions. Frost damage is one of the main reasons for the damage to reservoir slopes in cold regions. The freezing period in winter is long, and the thickness of the reservoir is too high. After the water freezes, it drives the soil to expand and bulge, causing the slope to be uneven. When the ice layer freezes with the slope, when the temperature rises, it will produce ice bending moment, which will push the slope to move, thus damaging the slope.

[0003] At present, the more effective and feasible method for preventing dam icing is mainly the pump disturbance deicing method, which mainly arranges dozens of submersible pumps along the dam. Each pump generates water flow disturbance at a depth of 0.5-1.0m where the dam contacts the water surface. Since the water temperature under the ice layer is significantly higher than the ambient air temperature, this method can easily achieve the purpose of preventing ice formation or deicing on the dam surface in the area where the pump is located.

[0004] However, when the water level in the reservoir changes, if the pump is submerged too deep, the water surface disturbance is not obvious; if it is submerged too shallow, the pump may heat up and burn or form a local jet without disturbance. The submerged depth of the pump cannot be automatically sensed and adjusted, and manual adjustment is required later. The workload is large when multiple pumps are used for batch processing, and the risk of working near the dam is also high, making it inconvenient to use. Utility Model Content
