Water wheel-shaped washdown type hydraulic turbine generator set

Abstract

The invention discloses a water wheel-shaped washdown type hydraulic turbine generator set. The water wheel-shaped washdown type hydraulic turbine generator set comprises a metal water wheel (1), a metal water wheel groove (2), a transmission case (3), a large capacity generator set (5) and a small capacity generator set (6), wherein the metal water wheel (1) is capable of rotating along a center rotary shaft (1a), the metal water wheel groove (2) leads water flow to the blades of a metal water wheel impeller (1b) of the metal water wheel, the transmission case (3) is connected to the outer end of the metal water wheel center rotary shaft, and the large capacity generator set (5) and the small capacity generator set (6) are connected to the two ends of an output shaft of the transmission case through a coupling (4) respectively. The water wheel-shaped washdown type hydraulic turbine generator set can efficiently use water energy, and the generating efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of hydropower generation, in particular to the technical field of hydroelectric generators. Background technique [0002] In today's world, with the rapid economic development, the demand for electric energy in various countries is getting higher and higher. Hydropower generation has always been one of the main ways of power supply, and developing the hydropower resources of rivers in an environmentally friendly way is one of the main directions for future power development. The traditional hydropower generation model must flood a large amount of land, induce geological disasters, cause serious ecological damage, and generate a large number of immigrants. Moreover, traditional low-head hydropower stations basically use tubular turbines, relying on water pressure and flow velocity to impact the impeller of the turbine, which is similar to the blades of an electric fan. , the utilization rate of water energy...

AI Technical Summary

Problems solved by technology

First of all, the basic way of using this kind of device is to place the power generation device in a natural or artificially constructed river channel, and simply use the water flow to impact the blades of the waterwheel to rotate to drive the generator set to generate electricity. The impeller of the waterwheel is open on the side, and the impact A large amount of water flow to the impeller is lost from the side of the impeller, and only a very limited momentum of the water flow can be used. The utilization rate of the potential energy of the water body is extremely low or even almost non-existent, and the power generation efficiency is limited; secondly, due to the nature of its "device", this type of It is difficult for the power generation device to produce scale effect, so it cannot become an important way of electricity production; thirdly, due to the power generation device placed in the stream, the speed of the waterwheel changes indefinitely when the flow, water level, flow velocity and waves are constantly changing. The generated electricity cannot be controlled, and the frequency of the current is unstable, which will cause damage to electrical equipment; fourth, this type of power generation device is small and installed in streams and rivers, and its ability to resist floods is poor
