The invention discloses a self-adaptive sewer cover plate which comprises a rectangular frame, wherein a plurality of mounting bars are arranged in the rectangular frame, the mounting bars are parallel to each other, the distances between adjacent mounting bars are equal and are two times of those between the outer mounting bars and the side wall of the rectangular frame, a pair of shielding plates is rotatably and symmetrically mounted on the lower side of each mounting bar, a plurality of mounting pipes are fixedly connected below the mounting bars, a pair of piston blocks is symmetrically,slidably and hermetically mounted in each mounting pipe, a low temperature evaporation liquid is arranged between the two piston blocks, the boiling point of the low temperature evaporation liquid is20-30 DEG C, the ends, far away from each other, of the two piston blocks are fixedly connected to a push rod, and the end, far away from the piston blocks, of the push rod penetrates the mounting pipes and leans against the shielding plates. The sewer cover plate provided by the invention achieves a self-adaptive effect. The cover plate is opened in rainy days, and rain water can enter a sewer through the cover plate, and the cover plate is closed in sunny days, so that peculiar smells in the sewer cannot be blown out.
本发明公开了一种自适应下水道盖板，包括矩形框，所述矩形框内设有多个安装杆，多个所述安装杆均相互平行，相邻两个安装杆之间的距离相等，且为外侧安装杆与矩形框侧壁之间距离的两倍，所述安装杆下侧对称转动安装有一对遮板，所述安装杆下方固定连接由多个安装管，所述安装管内对称滑动密封安装有一对活塞块，两个所述活塞块之间设有低温蒸发液，所述低温蒸发液的沸点在20℃‑30℃之间，两个所述活塞块相互远离的一端均固定连接有推杆，所述推杆远离活塞块的一端穿出安装管与遮板相抵。本发明提出的下水道盖板实现了自适应效果，在雨水天盖板开启，雨水能够通过盖板进入到下水道内，在晴天盖板关闭，使得下水道内的异味无法飘出。
