Abstract

The invention provides a hydroelectric turbine device. The device comprises a water pressing machine, a mechanical transmission device, a water turbine and a turbine device, wherein the water pressingmachine is arranged on the upstream of a river channel with a water level difference, the water turbine is arranged at the downstream of the river channel, the turbine device is arranged at the downstream of the river channel, the turbine device is connected with the mechanical transmission device, and the mechanical transmission device is connected with the water pressing machine. According to the device and method, the energy utilization efficiency of a hydropower station is improved, the water level difference required by upstream and downstream is lower for the specified power output, sothat the construction of the hydropower station saves materials and cost, and or else, the power generation effect of the hydropower station is better if the same water level difference are provided.

Description

technical field [0001] The invention belongs to the technical field of hydropower generation, and in particular relates to a turbine device and method for hydropower generation. Background technique [0002] The basic principle of hydroelectric power generation is to use the water level drop to cooperate with the hydroelectric generator to generate electricity, that is, to use the potential energy of the water to convert the mechanical energy of the waterwheel, and then use the mechanical energy to drive the generator to obtain electricity. It is cheap and non-polluting. [0003] At present, the usual process of hydroelectric power generation is as follows: after the water from the river is captured by the water blocking facilities, it is sent to the power plant through waterway facilities such as pressure tunnels and pressure steel pipes. The water turbine rotates and drives the generator to rotate. After the generator is excited, the generator builds up voltage and starts...
