The invention discloses a drainage device.Including at least one drainage container,The drainage container has a container body and a drainage unit.Among them,A holding space is formed at the top of the container body.At least one water guide is arranged at the upper end of the circumference of the container body.At least one water outlet is arranged at the lower end of the circumference of the container body；At least one drainage unit,Including a fixed plate,A vertical drainage plate,A horizontal drainage plate and an overflow plate,One end of the fixed plate is connected with the vertical drainage plate.The other end is connected with the overflow plate.The other end of the vertical drainage plate is connected with the horizontal drainage plate.The main function of the drainage unit is to change the direction of water flow. No matter whether the drainage unit is placed in the body of the container or not, the drainage container can be used for planting in the medium type. When the drainage unit is placed in the container body, the drainage container can be used for planting in the immersion type. The drainage device of the invention provides a way to configure more than a plurality of drainage containers. To provide more diversified planting options.本創作揭露一種引流裝置，包括至少一個引流容器，引流容器具有一容器本體與一個引流單元，其中，在容器本體頂部呈開口狀形成一容置空間，在容器本體周緣上端處設置至少一個導水口，在容器本體周緣下端設置至少一個出水口；至少一引流單元，包括一固定板、一垂直面引流板、一水平面引流板與一溢流板，固定板一端與垂直面引流板連結，另一端與溢流板連結，垂直面引流板另一端與水平面引流板銜接。引流單元主要的功能在於改變水流方向，不論容器本體內是否放置引流單元，引流容器皆可以使用在介質式型態的種植，而當引流單元放置於容器本體後，引流容器即可使用於浸水式型態的種植；本創作的引流裝置更提供一種配置複數個引流容器以上下壁掛的方式，提供更多樣化的種植選擇。
