Description

Inclined axis river power plant

technical field

The utility model relates to an inclined-axis river power generation device, which belongs to the field of new energy utilization.

Background technique

Energy is the material basis for human survival. With the increasingly severe energy crisis, human beings have turned their attention to the field of new energy. The kinetic energy of water flow is a kind of clean energy with concentrated energy density and abundant reserves. The development and utilization of water energy in rivers It plays a very important role in energy saving, emission reduction and sustainable development of energy.

At present, the main way to utilize the water energy of rivers is to use hydropower stations to generate electricity. However, hydropower stations are only suitable for large rivers, and there is still a lack of water energy utilization devices for small rivers. Some existing river power generation devices have poor flexibility and low efficiency. .
