Building drainage system adopting quick-drainage type anti-backflow floor drain
The invention is a divisional application of Chinese application 202010957939.2, and particularly relates to a building drainage system adopting a quick-drainage type anti-backflow floor drain. The building drainage system comprises a drainage pipe network, wherein the drainage pipe network comprises an indoor drainage pipe and the quick-drainage type anti-backflow floor drain; the quick-drainage type anti-backflow floor drain comprises a floor drain outer cylinder and a floor drain inner core; the floor drain inner core comprises a sewer pipe, a floating sleeve, a rotating sleeve, an arc-shaped wedge block and a turning plate; the floating sleeve is arranged on the sewer pipe in a sliding and sleeving manner; a plurality of spiral flow guide plates are uniformly distributed on the peripheral wall surface of the floating sleeve; the rotating sleeve is rotationally connected to the lower end of the sewer pipe and is positioned below the floating sleeve; a plurality of overflow structures are uniformly distributed on the peripheral wall surface of the rotating sleeve; the arc-shaped wedge block is fixedly connected with the rotating sleeve and rotates around the sewer pipe; and the turning plate is hinged to the lower end of the sewer pipe. According to the building drainage system disclosed by the invention, the rotating sleeve quickly rotates under the impact of water flow and the dual acting force of the arc-shaped wedge block; and by matching the spiral flow guide plates with the overflow structures, quick and timely drainage of high-flow ground water is realized.
本申请是中国申请202010957939.2的分案申请，具体涉及一种采用快排式防反水地漏的建筑物排水系统，其包括排水管网，排水管网包括室内排水管和快排式防反水地漏，快排式防反水地漏包括地漏外筒和地漏内芯，地漏内芯包括下水管、浮动套筒、转动套筒、弧形楔块以及翻板，浮动套筒滑动套设在下水管上，浮动套筒的外周壁面上均布有若干螺旋导流板，转动套筒转动连接在下水管的下端且位于浮动套筒的下方，转动套筒的外周壁面上均布有若干溢水结构，弧形楔块与转动套筒固定连接，且绕下水管转动，翻板铰接在下水管的下端。本发明转动套筒在水流的冲击以及弧形楔块的双重作用力下快速转动，通过螺旋导流板和溢水结构的配合，实现大流量的地面水快速及时地排出。
