Technical Field

The utility model relates to a river course is administered and flood control technical field especially relates to an ecological sluice device.

Background

The sluice is a low-water-head hydraulic structure built on the river channel and the canal and using the sluice to control the flow and adjust the water level, closing the sluice can block flood, block tide or raise the upstream water level, opening the sluice, can discharge flood, waterlogging, abandon water or waste water, and can also supply water to the downstream river channel or the canal. In the treatment of small rivers or drainage channels, river ecological base flow is often required to be ensured at the sluice so as to ensure the water requirement of river ecological water landscape and protect the river ecological environment.

Prior art floodgates are typically rubber floodgates or hydraulic barrages. The rubber sluice adopts a hollow dam bag made of high-strength synthetic fiber fabric, water is filled or inflated inwards to form a water retaining sluice, the upstream water level is controlled by adjusting the dam height so as to exert the benefits of irrigation, flood control, moisture blocking and the like, and the dam top can overflow. Although the rubber sluice has good anti-seismic and water-stopping effects and large span, the rubber sluice is easily damaged by the pointed floating objects in flood water, and the dam bag is abraded due to the vibration of the dam body caused by the water flow passing through the dam, so that the safety is poor, the rubber is easy to age, and water or gas filling equipment and the like are required, and the manufacturing cost is relatively high.

The hydraulic barrage is a metal structure matched with dredging for comprehensive treatment of river channels, and consists of a gate, a hydraulic system, an electrical system and a management room. Although the landscape water storage effect formed by water retaining of the hydraulic barrage is good, the hydraulic barrage has more matched electromechanical facilities, the construction and operation cost of a small river channel or channel is relatively high and uneconomical, and the gate release time is relatively slow.
