Description

Technical Field

[0001] This utility model relates to the field of river sluice gate technology, and in particular to a reversible sluice gate for river use. Background Technology

[0002] With the acceleration of urbanization and the concentration of population along rivers, the threat of floods to people's lives and property has become increasingly prominent. During the flood season, the water volume of rivers increases sharply and the water level rises rapidly. If the river flow is not properly regulated, floods can easily destroy riverbanks and embankments, and inundate surrounding towns and farmland. For example, the middle and lower reaches of many major rivers are flat and densely populated. After heavy rainfall during the rainy season, the risk of river flooding is extremely high. Although traditional fixed water-retaining structures (such as ordinary concrete dams) can play a certain role in blocking floods, they lack flexibility and cannot flexibly adjust the flood discharge according to the real-time flood flow. Therefore, a gate that can change its opening in a timely manner according to the flood situation and effectively discharge floodwater is needed to reduce the impact of floods on the riverside areas and ensure flood control safety.

[0003] Although tilting gates can achieve a certain degree of opening adjustment, their control precision may not meet the requirements in some situations where water level and flow control accuracy is extremely high. For example, in urban water supply systems, it is necessary to accurately control the flow at river intakes, and tilting gates may not be able to achieve precise micro-flow regulation like some electric regulating valves.

[0004] Therefore, we provide a waterway tilting gate to solve the above problems. Utility Model Content
