Description

Technical Field

[0001] The utility model relates to the technical field of hydropower generation, in particular to a safety protection device for flow-through components of a hydropower station. Background Art

[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electric power generation device. It is a key water conservancy project that realizes the conversion of water energy into electric energy. The sustainability of electric energy production requires the uninterrupted use of water energy in a hydropower station. Through the construction of a hydropower station reservoir system, the distribution of water resources in time and space is artificially adjusted and changed to achieve sustainable use of water resources.

[0003] In order to effectively convert the water energy in the reservoir into electrical energy, a hydroelectric power station needs to achieve this through a hydro-mechanical system. In order to avoid impact damage to the hydraulic flow components, a filter component will be set at the water inlet end to block and filter foreign matter in the water source to prevent it from flowing into the power generation system and causing damage to the blades. However, the existing filter components will cause blockage and accumulation of foreign matter when used for long-term filtering, requiring frequent manual cleaning and maintenance, which is time-consuming and labor-intensive. Therefore, we propose a safety protection device for the flow components of a hydroelectric power station. Utility Model Content
