Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to a river channel lifting gate. Background Art

[0002] A waterway gate is one of the devices installed in some water bodies or rivers to regulate water flow, also known as an overflow gate. A waterway gate usually consists of a horizontal bridge structure in the water and a hinge mechanism, which can be raised or lowered when needed to increase or decrease the water flow. Waterway gates are mainly used to control water levels, prevent floods, supply water, and generate electricity. Waterway gates are widely used in water conservancy projects and water resources management.

[0003] Existing waterway gates are mostly opened and closed by lifting. At the same time, in order to ensure the stability of the gate, the size and weight of the gate are often made relatively large. This means that when the discharge volume is low, personnel also need to start the gate to discharge the water. The frequent opening and closing of the gate will cause increased wear due to its size and weight. At the same time, the energy required for the opening and closing of the gate is also relatively large. In this way, opening the gate when the discharge volume is low will increase the wear of the gate and waste energy. Therefore, the existing river lifting gates still have certain shortcomings.

[0004] In summary, it is necessary to invent a river lifting gate. Utility Model Content
