Description

Technical Field

[0001] The utility model relates to the technical field of dam gates, in particular to an arc-shaped hydraulic lifting steel gate capable of adjusting water levels. Background Art

[0002] With global climate change and accelerating urbanization, the frequency and intensity of floods are increasing. Effective flood prevention and drainage require precise control of water levels in rivers, lakes, and reservoirs. Adjustable curved hydraulic lift gates can quickly adjust the gate opening height according to flood conditions, controlling water flow and water level, thereby mitigating the impact of floods. For example, during rainy seasons, timely raising the gates can increase the river's flood discharge capacity and prevent flooding. During dry seasons, the gates can be lowered to retain a certain amount of water to meet irrigation and ecological needs. The uneven distribution of water resources is a major global issue. To achieve the rational allocation of water resources, water conservancy projects need to be built to regulate and allocate water resources to different regions. Adjustable curved hydraulic lift gates can play an important role in various water conservancy projects, such as reservoirs, sluices, and canals, by controlling the gate opening height to achieve the rational allocation and utilization of water resources.

[0003] However, during the water blocking process, the existing water-blocking gates cannot adjust their water blocking height. When the river water accumulates too much, the water-blocking gates need to be fully opened for release. In the rainy season, full release is likely to cause floods downstream, and failure to release is likely to cause damage to the water-blocking gates. When the impact of the water flow is large, the gates may be partially deformed, resulting in an increase in the gap between the gates and the gate slots, resulting in water leakage, or the deformed gates may interfere with surrounding structures during the lifting process, affecting normal operation.

[0004] Therefore, we provide a curved hydraulic lifting steel gate with adjustable water level to solve the above problems. Utility Model Content
