Problems solved by technology

[0003] At present, most of the energy dissipation methods and devices for water conservancy and hydropower projects on the market are relatively simple in design, and most of them can only use part of the water potential to perform lateral impact energy dissipation on the rest of the water potential. Although this energy dissipation method can achieve the effect of energy dissipation , but the energy dissipation effect is not ideal. After the actual energy dissipation, the water source still has a relatively fast flow rate, which will still have a great impact on the downstream. Therefore, in view of the above problems, an energy dissipation method and device for water conservancy and hydropower projects are proposed

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to an energy dissipation method and device for water conservancy and hydropower engineering. Background technique [0002] With the development of science and technology and the progress of human life, people gradually began to use water to generate electricity. This method of power generation has the advantages of energy saving, environmental protection and high efficiency. The water energy used by hydropower is mainly the potential energy stored in the water body. To realize the conversion of water energy into electric energy, different types of hydropower stations need to be built, and the original river structure will be destroyed when the hydropower station is built. When discharging water for power generation, the discharged water often has a high velocity and relatively large kinetic energy. In order to To reduce the erosion of downstream ...
