Integrated hydraulic generator

Abstract

The invention relates to the technical field of hydroelectric generation, in particular to an integrated hydraulic generator which comprises a supporting shell, a transmission shaft, a turbine, a rotor and a stator. A turbine cavity, a closed cavity and a sealing assembly are arranged in the supporting shell. The sealing assembly comprises a separation cover plate, a supporting frame and an isolation cover shell, the separation cover plate is installed in the turbine cavity, the supporting frame is installed on the separation cover plate, and the isolation cover shell is installed on the supporting frame; the transmission shaft is arranged in the turbine cavity and penetrates through the separation cover plate and the supporting frame, the rotor is installed on the transmission shaft and arranged in the isolation cover shell, and the turbine is installed at the other end of the transmission shaft. The stator is connected with the supporting shell and is arranged in the closed cavity; air gaps are respectively arranged among the stator, the isolation cover shell and the rotor; the design of a coupler between the transmission shaft and the generator is omitted, the design size of the hydro-generator is effectively shortened, the friction loss between sealing parts is reduced, the generation power of the hydro-generator is improved, and the hydro-generator is convenient to use. 本发明涉及水力发电技术领域，更具体地，尤其涉及一体化水轮发电机，包括支撑壳体、传动轴、涡轮、转子、和定子；支撑壳体内设有涡轮腔、封闭腔，和密封组件；密封组件包括分隔盖板、支撑架、和隔离罩壳，分隔盖板安装在涡轮腔内，支撑架安装在分隔盖板上，隔离罩壳安装在支撑架上；传动轴设在涡轮腔内并且贯穿分隔盖板和支撑架，转子安装在传动轴上并且设在隔离罩壳内，涡轮安装在传动轴的另一端；定子与支撑壳体连接并且设在封闭腔内；定子、隔离罩壳及转子三者之间分别设有气隙；本发明取消了传动轴与发电机间的联轴器设计，有效地缩短水轮发电机的设计尺寸，并且减少密封部件之间的摩擦损失，提高水轮发电机发电功率，便于水轮发电机的使用。
