Abstract

The invention discloses a roller energy dissipation device. The roller energy dissipation device comprises a roller supporting frame, a roller and a steel shaft. The roller support frame is arranged on the foundation of the sea flood section, the steel shaft is arranged in the roller supporting frame, and the roller is arranged on the steel shaft to rotate along with the steel shaft. The roller energy dissipation device is arranged behind a stilling basin and is simple in structure, easy to operate and low in manufacturing cost. The roller energy dissipation device can effectively solve the scouring effect of the high-speed water flow on the downstream riverbed of a low-head hydraulic structures (sluices) for retaining water and discharging water in the discharging process, further protectthe riverbed, the riverbank and improve the water flow condition, and save the cost for reinforcing and repairing the riverbank.

Description

technical field [0001] The invention relates to a drum energy dissipation device, which belongs to the field of energy dissipation for sluices of water conservancy and hydropower projects. Background technique [0002] Sluices, as low-head hydraulic structures for retaining and releasing water in water conservancy and hydropower projects, are mostly built on the banks of rivers, canal systems, reservoirs, and lakes. Closing the gates can block floods, block tides, and raise water levels to meet the needs of upstream water diversion and navigation; opening gates can release floods, drain water, flush sand, or adjust flow according to downstream water needs. Sluices are widely used in water conservancy projects. [0003] During the discharge process of the sluice, the potential energy is converted into kinetic energy, and the flow velocity increases. Although most of the excess energy has been eliminated by the water flow through the stilling basin, there is still some excess...
