Background technique

Hydropower refers to the science and technology that studies technical and economic issues such as engineering construction and production operation of converting water energy into electrical energy. The water energy utilized in hydropower generation is mainly the potential energy contained in the water body. In order to convert water energy into electrical energy, different types of hydropower stations need to be built.

When hydropower is generated, the potential energy of the water level is used to impact the impeller to generate electricity. When the water flow falls from a high place, it will produce a large impact force. At this time, if the water flow is mixed with foreign objects such as driftwood, aquatic plants, and stones, it may directly cause damage to the impeller. However, when a filter is used to filter the water flow, the potential energy of the water flow will be lost, so a device that can filter impurities without reducing the potential energy of the water flow is needed.
