摘要
引水枢纽首部的漂浮物影响水工建筑物和水质,漂浮物高效治理问题亟待解决.以拦、导、排为基本思路,对水库治漂浮槽进行了改造,设计出旋转式浮筒拦排.对旋转式浮筒拦排在不同来水流量、不同安装角度和不同漂浮物的情况进行了试验分析和讨论,结果表明:来水流量越大导排漂效果越好;合理的安装角度对驱动浮筒的转动起到一定作用;一定质量和运动速度的漂浮物对导漂效果起着积极作用.针对改扩建工程和新建工程分别提出导排漂设计方案.本研究可为引水枢纽漂浮物的治理起到积极推动作用,为其他类型建筑物的导排漂设计提供参考.
Abstract
The treatment problem that floating debris at the head of water diversion affect hydraulic structures and water quality cannot be ignored.Based on the basic idea of"block,guide and discharge",the floating bucket barrier-drift of the reservoir is reconstructed and a rotary one is designed.Experimental analysis and discussion of rotary floating bucket in different inflow,different installation angles and different floating objects are carried out.It is found that the bigger the incoming water flow is,the better the effect of drift guiding and drainage is,the reasonable installation angle plays an important role in driving the rotation of the bucket,and the mass and speed of floating objects play a positive role in guiding drift.Meanwhile,the design schemes of guiding and draining drift are given respectively for the reconstruction project and the new project.The design promotes the treatment of floating objects in diversion hydroproject and provide reference for the design of other types of multi-purpose hydroproject.
