Rainwater hopper and roof drainage system
The invention relates to the field of building rainwater drainage, and discloses a roof drain and roof drainage system which comprises a shell and a fan wheel, a water guide channel and a drainage channel are arranged in the shell, the fan wheel is rotationally arranged on the shell and arranged in the water guide channel, and the drainage channel penetrates through the lower portion of the shell and communicates with the water guide channel. A water inlet communicated with the water guide channel is formed in the shell, and a first water guide rib is arranged on the inner wall of the drainage channel. The device has the beneficial effects that water flow drives the fan wheel to rotate to form rotational flow, the rotational flow is matched with the first water guide ribs to enable the water flow to fall down along the pipe wall, the water-gas mixed flow phenomenon caused by direct falling of the water flow is avoided, collision between the water flow and the pipe wall is reduced, the water flow speed is increased, and meanwhile noise caused by collision between the water flow and the pipe wall is reduced; and meanwhile, a certain strength increasing effect can be achieved.
本发明涉及建筑雨水引流领域，公开了一种雨水斗和屋顶排水系统，该雨水斗和屋顶排水系统包括：外壳和扇轮，外壳内部设有导水通道和排水通道，扇轮转动设于外壳上并设于导水通道内部，排水通道贯穿外壳下方并与导水通道连通，外壳上设有与导水通道连通的进水口，且排水通道内壁设有第一导水筋。本发明的有益效果为：水流带动扇轮转动形成旋流，并与第一导水筋配合使水流沿管壁下落，避免水流直接下落产生水气混合流现象，并且减少水流与管壁的碰撞，加快水流速度的同时降低了水流碰撞管壁引起的噪音，同时还能起到一定的增加强度作用。
