Abstract

The invention provides a hydraulic-driving generator unit. The hydraulic-driving generator unit comprises a hydraulic driving device and a power generation assembly. The hydraulic driving device comprises an outer ring and a core. One or more steps of sub flushing flow channels are formed between spraying ports and discharging ports of the outer annular face of the core, the water flow enters liquid inlet channels, is sprayed out through the spraying ports of the core and the sub flushing flow channels step by step and acts on two or more driving concave parts of the outer ring in the circumference direction, thrust is generated to the driving concave parts to push the outer ring to rotate for working, power output is achieved, and finally the water flow is discharged through the discharging ports of the core via liquid discharging channels. Rotation working of the outer ring is used as kinetic energy for power generation of the power generation assembly.

Description

technical field [0001] The invention relates to the field of hydroelectric power generation, in particular to a hydraulically driven generating set with small volume and high conversion efficiency. Background technique [0002] A hydroelectric generator set is a mechanical device that converts the potential energy of water into electrical energy. A traditional hydroelectric generator set includes a water turbine and a generator. A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery in fluid machinery. Most of the modern water turbines are installed in the hydropower station to drive the generator to generate electricity; Then it is discharged downstream through the tail water pipe, the higher the water head and the greater the flow, the greater the output power of the turbine. [0003] Existing water turbines generally consist of volutes, fixed guide vanes, water guiding mechanisms, r...
