Hydraulic turbine generator

The invention relates to a hydraulic turbine generator. The hydraulic turbine generator comprises a turbine generator shell and a radial flow turbine device arranged in the turbine generator shell. The turbine generator shell comprises a water inlet pipe, a radial flow turbine device chamber and a water outlet pipe. The water inlet pipe comprises a reducing water inlet and a diverging water outlet. The radial flow turbine device chamber comprises a cylindrical chamber body and end covers, wherein the two ends of the cylindrical chamber body are covered with the end covers in an airtight mode. The water outlet pipe comprises a reducing water catchment port and a diverging drainage outlet. The radial flow turbine device comprises flow guide tubes and radial flow turbines arranged in the flow guide tubes. Each flow guide tube comprises a plurality of flow guide blades. Each radial flow turbine comprises a plurality of turbine blades and a turbine shaft, wherein the radial flow turbine is arranged on the corresponding end cover through the turbine shaft in a penetrated mode. According to the hydraulic turbine generator, a built-in flow guiding device is used for adjusting the impact direction of water flow, the built-in radial flow turbines are adopted to convert and output energy, the potential energy conversion rate of the water flow is increased, and the hydraulic turbine generator has the advantages of being appropriate in size and convenient to use and maintain.
