This creation relates to the improvement of a three-dimensional aquaculture device, in particular, a plurality of culture tanks are arranged side by side in multiple layers, and a water injection pipe and a drainage pipe are respectively connected in series between each culture box, and in each culture A siphon discharge unit is provided at the position where the box is connected to the drainage pipe, and a siphon phenomenon can be generated. The water in each breeding tank is quickly and continuously discharged into the drainage pipe from the bottom, and the sinking can be discharged. The design of the aquaculture equipment that continuously discharges the waste and the remaining feed to keep the water quality clean and shorten the aquaculture time is a novel, progressive and industrially applicable creation.本創作係有關一種立體水產養殖裝置之改良，尤指一種以複數個養殖箱以多層疊置併排，並於每一養殖箱間分別串聯設有注水管路及排水管路，且於每一養殖箱體與排水管路相連接之位置，均設有一虹吸排出單元，而可產生虹吸現象，將每一養殖箱內之水由底部快速持續排入排水管路中，而可將沉底之排泄物及剩餘飼料持續排出循環，保持水質乾淨，縮短水產養殖時間之養殖裝置設計，為一甚具新穎性、進步性及可供產業上應用之創作。
