Abstract

The invention relates to the technical field of flood discharge channels, in particular to an energy dissipation strip type flood discharge device. The device comprises a straight-section flow channel and a bent-section flow channel. At least one energy dissipation strip set is fixedly installed at the upper end of the bottom of the bent-section flow channel in the flow direction. The energy dissipation strip set comprises three energy dissipation strips which are overlaid and can cover the section of the bottom of the bent-section flow channel. The three energy dissipation strips are distributed at intervals in the flow direction, and every two energy dissipation strips are staggered. Each energy dissipation strip can comprise an energy dissipation rubber strip and a rubber strip installation base for fixing the energy dissipation rubber strip to the bent-section flow channel. The energy dissipation strip type flood discharge device is reasonable and compact in structure and convenient to use. The three energy dissipation strips in each energy dissipation strip set can be overlaid to cover the section of the bottom of the bent-section flow channel and form an energy dissipation barrier, the original water flow trend is disorganized, water flow is disordered, the flow speed is decreased, and water flow potential energy is reduced; the device can be well applied to low-falling-head and small-flow hydraulic potential, impact and scouring intensity of water flow for a flood discharge channel wall is reduced, safe and stable operation of a hydraulic power plant is ensured, and canal collapsing accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of spillway, and relates to an energy-dissipating bar-type flood discharge device. Background technique [0002] The hydropower plant mainly relies on the hydraulic potential energy to drive the water turbine to rotate, and the water turbine drives the generator to rotate and cut the magnetic force line to generate electricity; however, when the hydropower plant suddenly loses pressure due to other external reasons, a large amount of flow cannot be discharged normally and needs to be discharged through the spillway ; For low-head hydropower stations, the flow of the spillway is small, the drop is low, and the slope is gentle. Although the potential energy accumulated by the water flow is small, for the spillway with a certain curvature, the accumulated potential energy of the water flow still exists at the bend. There is a risk of channel collapse due to the impact of the spillway wall, slope or bottom. Co...
