Description

Technical Field

[0001] The utility model relates to the technical field of hydropower generation, in particular to a non-drop hydropower generation device. Background Art

[0002] Hydroelectric power generation uses water with potential energy from rivers and lakes to flow to lower places, converting the potential energy contained in it into kinetic energy of turbines, and then using turbines as motive force to drive generators to generate electricity. Water power (with water head) is used to drive the hydraulic machinery (turbine) to rotate, converting water energy into mechanical energy. If another machine (generator) is connected to the turbine, it can generate electricity as the turbine rotates, and then the mechanical energy is converted into electrical energy. In a sense, hydroelectric power generation is the process of converting the potential energy of water into mechanical energy and then into electrical energy. Because the voltage of electricity generated by hydroelectric power plants is relatively low, in order to transmit it to users far away, the voltage must be increased by transformers, and then transmitted to substations in user-concentrated areas by overhead transmission lines, and finally reduced to a voltage suitable for household users and factory electrical equipment, and then transmitted to various factories and households by distribution lines.

[0003] In modern society, science and technology are advancing at a rapid pace, and the demand for energy is also increasing. As the pressure on energy demand continues to increase, people are also increasingly developing energy. Hydropower generation is an important invention of people's new energy and clean energy, but hydropower generation generally uses the kinetic energy generated by the drop in water flow to generate electricity. Therefore, it is necessary to build dams to raise the water level, which is costly and takes a long time to build. my country has a large number of rivers and streams, and many of them have high water flow rates, but it is not easy to build dams for power generation in many places, and people cannot make good use of their water resources, resulting in a huge waste of resources.

[0004] At present, the most mature hydroelectric power generation technology is to build dams to store water and use the potential energy of water to generate electricity. However, due to the geographical location of the dam, it will inevitably involve many problems such as flooding farmland and migrating population. It is not suitable for generating electricity in flowing small rivers. In addition, for mountainous areas or remote rural areas, there are mostly small streams and ditches, and small dams cannot be built for water storage and power generation. The cost of building dams is high and rural residents cannot afford it. In addition, the existing hydroelectric power generation system is to set the hydroelectric generator below the reservoir and use the potential energy of the height difference of the water flow drawn from the reservoir to generate electricity. However, in order to draw the water from the reservoir and generate the potential energy of the height difference, it is necessary to build multiple water diversion channels from top to bottom on the reservoir, resulting in high cost of building water diversion channels, which does not meet the requirements of low cost. In addition, the existing hydroelectric generator is driven by a giant rotating cylinder to generate electricity. It is large in size and requires a large space. The structure is complex and costly, which does not meet the requirements of simple structure and low cost. Utility Model Content
