摘要
为了满足堰塞湖应急抢险对大流量虹吸装备研发制造的需求,首先分析了堰塞湖应急抢险大功率虹吸技术装备的应用场景与研发难点,对装备系统进行了针对性总体设计,介绍了设计中采用的水力流场流态优化、数字智能化调控、工业模块化装配等关键技术.该装备包含潜水整流单元、液气交换单元、智能监控单元三部分.其中整流单元采用群孔并联射流的管道进流方式,智能监控单元采取数据分布式管理,为系统的稳态运行提供数据支撑.该新装备具有运行稳定、泄水量大、安装简便、启动快速等优点,泄流能力可达3500～15000 m3/h,不仅可以用于堰塞湖应急排水抢险,也可以用于其他领域的大流量输排水作业.
Abstract
In order to satisfy the requirements about siphon equipment of large flow capacity in emergency rescue of barrier lakes,we examine the application scenarios and development challenges of high-powered siphon equipment for emergency rescue in barrier lakes scenarios.A targeted holistic design was conducted for the barrier lakes siphon equipment system.We present crit-ical technologies such as hydraulic flow field optimization,digital intelligent control,and industrial modular assembly for dammed-lake siphon drainage.The equipment contains three parts of submerged flow correct unit,liquid air exchange unit,intelligent monitoring unit.The flow correct unit adopts pipe inflow way of paralleling hole-group jet,and the intelligent monitoring units a-dopts distributed data management.The developed siphon is characterized by steady operation,large flowing quantity,easy assem-bly and fast start-up with discharge capacity surpassing 15000 m3/h.The developed equipment can not only be applied in emer-gency drainage rescue operations for dammed lakes,but also in other fields requiring high volume water extraction and drainage.
