The utility model discloses a reversing plate discarding device, which is arranged in a rainwater inspection well, and comprises a short pipe and a discarding reversing plate. The short pipe is respectively connected with the inlet pipe and the outlet pipe of the rainwater inspection well, and the discarded overturning plate is arranged in the rectangular hole directly below the short pipe, and a rotating shaft is arranged in the middle of the discarded overturning plate, and the discarded overturning plate rotates around the rotating shaft. The weight of the front end of the discard turnover plate is larger than that of the rear end of the turnover plate, and the backwater of the discard turnover board is provided with a collecting tank. In the early stage of rainfall, the small flow rainwater enters the downhole from the hole at the front end of the overturning plate and discards it from the branch pipe. In the later stage of rainfall, the rainwater flow increases and the weight of the back end of the overturning plate increases gradually to the level. The rainwater flows through the short pipe into the outlet pipe for subsequent rainwater collection. The utility model has the advantages of simple structure, strong applicability, convenient operation and maintenance, and can realize the timely diversion of discarded rainwater and rainwater collection.

一种翻板弃流装置
本技术涉及雨水利用技术,具体涉及一种雨水弃流装置。
技术介绍
近年来,雨水收集回用在工程中应用广泛。降雨初期,由于雨水溶解了空气中的大量污染性气体,落到地面后,又冲刷沥青混凝土道路等,使得初期雨水中含有大量的污染物质。雨水的污染程度较高,甚至超出普通城市污水的污染程度。因此,污染物浓度较高的初期雨水,需进行弃流后再收集。常用的初期雨水弃流方式有以下几种:(1)容积弃流法根据初期雨水弃流厚度及汇水面积计算水池容积,水池充满后雨水再进入后续处理构筑物。此弃流方式需另建水池,汇水面很大时,容积较大,投资增加。(2)切换式弃流在雨水检查井中同时埋设连接下游雨水井和下游污水井的两根连通管,在两个连通管入口处设置手动或自动闸阀进行切换。进水管道上安装雨量计,当雨量计流量达到设定弃流量时,弃流管上闸阀关闭,开启下游管道闸阀,后期雨水进入收集系统。此弃流方式需增加自控设备,安装复杂且后期维护成本较高。
技术实现思路
针对现有雨水弃流方式存在的问题,本技术推出一种翻板弃流装置,通过弃流翻板控制,在降雨初期降雨强度较小时弃流初期雨水,降雨后期降雨强度增大后实现雨水收集。此装 ...
