Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and particularly relates to a high-strength arc gate structure. Background Art

[0002] The gates used for overflow dams and various types of sluice gates have the following structural forms: plane gates, arc gates, arch gates, round roller gates, sector gates, roof gates, tongue flap gates, etc. Among them, the arc gate has significant functions. Its main functions are to regulate water levels, control the flow rate and velocity of water flow, and prevent floods. Compared with other types of gates, the arc gate has the advantage that no gate slots need to be set. This not only reduces the manufacturing and installation costs of the gate but also avoids the influence of the resistance generated by the gate slots on the water flow, making the gate more stable during operation. During the opening and closing process of the arc gate, since the acting force of the water flow on the gate is distributed along the curvature direction of the gate, the force required for opening and closing is relatively small. This makes the arc gate more convenient to operate, reduces the requirements for the opening and closing equipment, and also reduces energy consumption. When the arc gate is closed, the gap between the top of the gate and the bottom sill is small, so the water leakage is also relatively small. At the same time, because the gate is arc-shaped, the water flow can flow through more smoothly when passing through, reducing the turbulence of the water flow and energy loss. This excellent hydraulic condition helps to improve the operation efficiency of the gate and reduce the waste of water resources. However, the existing arc gate structure has high production costs and a short service life. Therefore, a high-strength arc gate structure with high structural strength, low production costs, and a long service life is needed. Content of the Utility Model
