Municipal road drainage structure with backflow prevention function
The municipal road drainage structure with the backflow prevention function comprises a shell, a well lid is arranged at the top of the shell, a water inlet is formed in the top of the shell, and a cylinder is installed in the water inlet; the inner wall of the cylinder body is fixedly connected with an annular bulge, and the whole annular bulge is trumpet-shaped; when the device is used, the floating ball can always float on the water surface with the water level rising, the floating ball can continuously rise in the barrel along with continuous rising of the water level in a sewer, and in the process, due to the fact that the interior of the floating ball is hollow and is provided with the balancing weight, the balancing weight is always kept at the vertically-downward position; and the sealing ring mounted on the surface of the floating ball can always keep a vertically upward position on the water surface, and when the water level rises to the water inlet, the sealing ring can be attached to the annular bulge to close the opening of the water inlet, so that the phenomenon that accumulated water flows back to the road surface due to rising of the water level in the sewer is avoided.
本发明公开了一种具有防倒流功能的市政道路排水结构，包括外壳，所述外壳的顶部设有井盖，所述外壳的顶部设有进水口，所述进水口的内部安装有筒体；所述筒体的内壁固定连接有环形凸起，所述环形凸起的整体呈喇叭状；本发明使用时，浮球能够始终漂浮在升高水位的水面上，随着下水道中水位的继续升高，能够使浮球在筒体内持续上升，该过程中，由于浮球内部为中空状，且安装有配重块，使配重块始终保持垂直向下的位置，且浮球表面安装的密封圈能够在水面上始终保持垂直向上的位置，当水位升高至进水口时，密封圈能够与环形凸起贴合，使进水口的开口闭合，从而避免下水道内部水位升高而导致积水倒流至路面现象。
