Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and power generation, and more specifically, particularly relates to water conservancy and power generation equipment with an anti-blocking function. Background Art

[0002] A hydroelectric generator set is also called a "water turbine generator set". Each turbine and its matching generator in a hydropower station form a power generation unit, which is the main power equipment for producing electricity in the hydropower station. When the water flow used by the hydropower station passes through the turbine, the water energy is converted into mechanical energy that drives the machine to rotate; the generator then converts the mechanical energy into electrical energy for output.

[0003] In the actual use of current hydroelectric generators, since the water flow contains various impurities and particles, the common practice is to add a filter at the water inlet of the turbine, so as to block the impurities and particles in the water flow and prevent the impurities and particles from entering the turbine and affecting the use of the turbine. However, during the use of the filter, the impurities and particles in the water flow can easily cause it to be blocked, and the blocked filter will affect the water inlet, thereby affecting the normal operation of the turbine and reducing the power generation efficiency of the hydroelectric generator.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hydropower generation equipment with anti-blocking function is provided, in order to achieve a more practical purpose. Utility Model Content
