Concave overflow well lid
The invention discloses a concave overflow well lid which is suitable for an overflow occasion with the flow smaller than 0.12 m < 3 >/s. The concave overflow well lid comprises a well lid body used for being arranged in the water inlets of overflow wells or the water inlet ends of drainage pipes in a supported mode, and the upper surface of the well lid body is concaved inwards towards the interior of an overflow well or the interior of a drainage pipe to form an overflow cavity with an upper portion open. The opening position of the overflow cavity is equal to or lower than the water inlet of the overflow well or the water inlet end of the drainage pipe; a plurality of overflow ports penetrating through the wall surface are formed in the wall surface of the overflow cavity, and the overflow ports are used for intercepting and filtering impurities in overflow water flowing into the overflow cavity and then introducing the impurities into corresponding overflow wells or the drainage pipes; the wall face of the overflow cavity is further provided with a first turbulent flow strip protruding outwards, and the first turbulent flow strip is used for enabling the overflow water in the overflow cavity to generate turbulent flow. According to the concave overflow well lid, the overflow capacity is high, rainwater loss can be effectively reduced, the rainwater collection and reutilization rate is increased, and the problem that the overflow amount becomes small due to the fact that sundries are accumulated on the outer edge of the overflow well or the drainage pipe can be effectively solved.
本发明公开了一种凹形溢流井盖，适用于流量小于0.12m3/s的溢流场合，凹形溢流井盖包括：用于支设于溢流井的进水口或排水管的进水端中的井盖本体，井盖本体的上表面朝溢流井内或排水管内方向内凹形成上部敞口的溢流腔，且溢流腔的敞口位置等于或低于溢流井的进水口或排水管的进水端位置；溢流腔的壁面上开设有若干贯穿壁面的溢流口，溢流口用于对流入溢流腔的溢流水中的杂质进行拦截过滤后引入对应设置的溢流井或排水管内；溢流腔的壁面上还设有外凸的第一紊流条，以用于使溢流腔中的溢流水产生紊流。本发明的凹形溢流井盖的溢流能力强，可有效减少雨水流失，提高雨水收集再利用率，还可有效避免杂物堆积在溢流井或排水管外边缘导致溢流量变小的问题。
