Tail water power generation system of hydroelectric power plant

Abstract

The invention discloses a tail water power generation system of a hydroelectric power plant. The power generation system comprises a water turbine, a speed increasing device and a generator; the water turbine is horizontally positioned above a river bed; two ends of a turbine shaft of the water turbine are rotationally connected with bases on two sides of the river bed; a driving gear is arranged on one end of the turbine shaft; a driven gear of the speed increasing device is in engaged transmission with the driving gear; a one-way clutch includes a center bearing, and an inner ring body and an outer ring body at the outer periphery; the outer ring body and the driven gear are both fixed on a transmission shaft, and coaxially rotate; the inner ring body is connected with the transmission shaft through a center bearing; an inertia force disc is rotationally connected with the transmission shaft; the inner ring body is connected with the inertia force disc through multiple pin pieces; and a transmission wheel of the generator is in transmission connection with the inertia force disc. The power generation system effectively adjusts the condition of unbalanced power generation of the generator caused by flowing speed fluctuation of water currents.

Description

technical field [0001] The invention relates to a water conservancy power generation system, in particular to a tail water power generation system of a hydropower station. Background technique [0002] As we all know, hydropower is an inexhaustible clean energy source. The use of hydropower does not require fuel, nor will it produce radiation or air pollution, so it has attracted the attention of countries all over the world. However, because the traditional hydroelectric power generation needs to build embankments and dams, the cost is high, and the blades of the water turbine are restricted, so it can only drive the generator matching the water turbine and many other factors, hindering the development of hydropower generation, so an investment can be invented. A small, quick-return hydroelectric power generation system is one of the goals that countries all over the world are looking for. [0003] Hydropower generation can generally be divided into stream type, reservoir ...

Problems solved by technology

However, due to the high cost of building dikes and dams for traditional hydropower generation, and the fact that the blades of the water turbines are restricted, they can only drive generators that match the water turbines and many other factors hinder the development of hydropower generation. Therefore, an investment A small, quick-acting hydroelectric power generation system is one of the goals that countries all over the world are looking for
