Description

Technical Field

[0001] The utility model belongs to the technical field of gates, and in particular relates to a river flood discharge gate. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. In water conservancy facilities, gates can intercept water flow, control water levels, regulate flow, and discharge sediment and floating objects. However, existing water conservancy gates are prone to wear and tear due to frequent lifting and lowering, which reduces the service life of the gates.

[0003] After searching, the announcement number: CN220352748U announced a lifting type hydraulic gate. In the utility model, the gate plate is set and the auxiliary gate assembly is set in the middle of the gate plate to meet the needs of daily flood discharge and large-volume flood discharge in the river. In addition, the operation of the gate plate and the opening and closing of the auxiliary gate assembly are adjusted only by adjusting the driving assembly. However, this device completes the lifting transmission by meshing. Although the transmission is smooth, the speed is slow, and the turbulent water flow has a large impact on the gate plate during the flood discharge process, thereby reducing the service life of the gate plate.

[0004] Therefore, a river flood discharge gate is designed to solve the above problems. Utility Model Content

When the two sets of steel gate plates are closed, their outer surfaces are interlocked, so that the two steel gate plates present a V-shaped structure. The tip of the V-shaped steel gate plate is the water-facing surface. The turbulent water flow impacts the steel gate plate to reduce the overall force strength, effectively preventing excessive positive impact from causing damage to the steel gate plate, and the silicone sealant layer at the connection further strengthens the tightness of the connection to prevent water leakage, and the multiple sets of buffer rubber pads opened on the water-facing surface can effectively alleviate the impact of the water flow, thereby increasing the service life of the steel gate plate.

[0006] When opening the gate, the thrust cylinder on the top is started through the control end, and its piston end pulls the hinged rod, which rotates along the central axis of the hinged ear plate 1 and drives the connecting plate to deflect. Through the hinged cooperation of the outer positioning block and the hinged ear plate 2 on the top of the steel gate plate, the thrust cylinder can pull the steel gate plate to rotate along the positioning axis and the water retaining frame to form an opening effect; in order to avoid the excessive water pressure caused by deep floods making it difficult to open the steel gate plate, the device can pre-start the electric telescopic rod inside the blind hole when discharging water, and its output end pulls the push rod, and the push rod pulls the water-permeable plate to move steadily upward on the inner wall of the groove surface of the limit groove, thereby making the bottom of the steel gate plate present a multi-flood discharge opening effect, thereby balancing the pressure difference between the inlet and outlet sides, and ensuring the normal opening and closing of the steel gate plate.
