Rain and sewage diversion anti-backflow device for sponge city
The invention discloses a sponge city rain and sewage diversion anti-backflow device, and belongs to the technical field of rain and sewage diversion. The device comprises a non-return box internally provided with an anti-backflow unit and a filtering unit, the anti-backflow unit comprises a first water inlet plate and a second water inlet plate, the second water inlet plate is provided with a blocking block corresponding to a water inlet hole of the first water inlet plate in position, and the end of the second water inlet plate is in sliding fit with the inner wall of the non-return box; the filter unit comprises a filter plate, one end of the filter plate is inserted into the inner wall of the non-return box, and the other end of the filter plate is connected with the non-return box through a detachable part. When rainwater and sewage flow back, water flow impacts the second water inlet plate, so that the blocking blocks on the second water inlet plate are inserted into the first water inlet holes in the first water inlet plate and are clamped, the water flow cannot flow back through the first water inlet holes, and the anti-backflow effect is obvious. In addition, through the arrangement of the filter unit dismounting and connecting part, the filter plate can be conveniently dismounted and mounted, and the practicability of the device is improved.
本发明公开了一种海绵城市雨污分流防倒灌装置，属于雨污分流技术领域；该装置包括内部具有防倒灌单元和过滤单元的止回箱，防倒灌单元包括第一进水板和第二进水板，第二进水板上设置有与第一进水板进水孔位置对应的堵块，第二进水板端部与止回箱内壁滑动配合；过滤单元包括过滤板，过滤板一端与止回箱内壁插接，过滤板的另一端通过拆接部与止回箱连接。当发生雨污回流时，水流对第二进水板进行冲击，使得第二进水板上的堵块插设到第一进水板上的第一进水孔内部并卡合，水流无法通过第一进水孔进行倒灌，防倒灌效果明显。此外，通过过滤单元拆接部的设置，实现过滤板可以便捷拆装，提高了装置的实用性。
