  The present invention relates to a hydroelectric power generation apparatus, and in particular, can efficiently generate power by using flowing water flowing through an intake channel such as an agricultural channel that leads to a river.

  2. Description of the Related Art Conventionally, as an example of a hydroelectric power generation apparatus, there is an apparatus in which a water turbine is arranged in the middle of an agricultural waterway connected to a river, the water wheel flowing through the agricultural waterway is rotated, and a generator is driven to generate electricity.

According to the above configuration, power generation is performed using running water that has been wastefully discharged and is not used for anything other than farm work, so it is economical and does not generate carbon dioxide during power generation. There is also an advantage of being friendly. In addition, in the case of solar power generation, power generation is not possible at night, the power generation amount is significantly reduced when it is cloudy or rainy, and a charging device is required to charge the power generation amount during the daytime at night. . On the other hand, in the case of hydroelectric power generation, there is an advantage that power can be generated continuously for 24 hours regardless of day or night. In addition, there exists what was described in patent document 1 as a related technique.
