Flat plate weir ecological flow transformation and metering system and control method
The invention relates to a flat plate weir ecological flow transformation and metering system and a control method, and belongs to the technical field of hydraulic engineering, a water retaining device comprises a water retaining baffle, a first open groove is formed in the middle of the water retaining baffle, water stopping convex grooves are formed in the two side walls of the first open groove respectively, a connector is installed on the water retaining baffle, and the connector is connected with the first open groove. The connector is located on the backwater side of the water blocking baffle. The water measuring device comprises a water measuring weir plate, water stopping grooves are formed in the two sides of the water measuring weir plate respectively, a second open groove is formed in the water measuring weir plate, and the second open groove is in a triangular weir notch thin-wall weir form; the water retaining control mechanism comprises an electric control hydraulic rod, the top end of the electric control hydraulic rod is connected with the connector, and the tail end of the electric control hydraulic rod is fixed under the riverbed ground. Accurate metering and real-time regulation and control of the discharged flow can be achieved, the applicability of the device is enhanced, and it is effectively ensured that the ecological flow of a downstream river reaches the standard.
本发明涉及一种平板堰生态流量改造和计量系统及控制方法，属于水利工程技术领域，所述挡水装置包括阻水挡板，所述阻水挡板中间设置有第一开槽，所述第一开槽的两侧壁上分别设置有止水凸槽，所述阻水挡板上安装有连接器，且所述连接器位于所述阻水挡板的背水侧；所述量水装置包括量水堰板，所述量水堰板的两侧分别设置有止水凹槽，所述量水堰板上设置有第二开槽，所述第二开槽采用三角堰缺口薄壁堰形式；所述挡水控制机构包括电控液压杆，所述电控液压杆的顶端与所述连接器相连接，所述电控液压杆的末端固定于河床地面以下。本发明能够对实现下泄流量的准确计量与实时调控，增强了装置的适用性，有效确保了下游河道生态流量达标。
