AI Technical Summary

Technical Problem

In existing water conservancy projects, the concrete water-retaining structures on both sides of the river are at a fixed height, which cannot effectively cope with floods with large flow rates. This can cause floods to overflow the water-retaining structures, posing a safety hazard.

Method used

Design a slope protection and flood control device for water conservancy projects, including a sliding retaining wall and a floating shield. The retaining wall is driven by buoyancy to slide out of the dam body to increase its height when floods occur, and the floating shield keeps it closed under normal water levels to prevent silt from entering the cavity and ensure the stable operation of the device.

Benefits of technology

It effectively suppresses flood overflows over the dam body, improves dam safety, and maintains the cleanliness and stable operation of the device during multiple water level changes, reduces the adverse effects of sediment deposition on the device, and enhances flood control capabilities.

Abstract

This invention provides a slope protection and flood control device for water conservancy projects, relating to the field of slope protection and flood control. The invention includes a dam body with a cavity inside, the cavity being connected to the river channel side via an inlet; a retaining wall slidably disposed within the dam body, used to switch between a first state and a second state. In the first state, the retaining wall is located within the dam body; in the second state, the retaining wall extends out of the dam body to increase the dam's height; a driving component disposed within the cavity, configured to use buoyancy to drive the retaining wall to switch from the first state to the second state when the water level in the cavity rises; and a floating shielding component at the inlet, used to open the inlet using its own buoyancy when the river water level rises to the inlet. When encountering a large-flow flood, the retaining wall can form an additional blocking structure, which helps to suppress flood overflowing the dam body, thereby improving the safety of the dam body.
