The traditional method of hydropower generation is to install the power generation device upstream of the water source, so that the water source flows through the power generation device to generate electricity, and the water source then flows downstream for irrigation or people's livelihood. Use water.

Since the water source flows through the power generation device to generate electricity, the water source is almost lossless output. Therefore, if the water source can be used for power generation multiple times and repeatedly, it can not only supply and transmit more power, but also greatly reduce the cost of power generation.

The stepped hydroelectric power generation device of this invention includes: a channel with an upstream end and a downstream end. The upstream end is used to introduce water source. There are several supporting parts between the upstream end and the downstream end; several power generation units. Separately provided in each supporting part, the power generation unit is composed of a casing with a flow channel. The flow channel has an inlet and an outlet. The inlet faces the upstream end to allow flow from the upstream end to the downstream end. The water source is guided from the inlet through the flow channel and output from the outlet. The outlet is hollow and suspended in each receiving part, so that the water source can fall from the outlet to each receiving part. Each power generation unit has a generator, the shaft of the generator is connected to an impeller, and the impeller is located at the output port; and a current collecting assembly is used to collect and output the electric power generated by the power generation units.

In this way, each receiving portion can collect water from a higher liquid level and then introduce it through the inlet, so as to enhance the impact force of the water source.

Wherein, the downstream end has a reservoir and a water pumping member, and the water pumping member is used to draw the water liquid accumulated in the reservoir to the upstream end. In this way, the water liquid accumulated in the reservoir can be pumped to the upstream end through the water pumping member, so as to reuse the effect of the water resources.
