Sand blocking and water collecting system for head hub of hydropower station

The utility model belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a sand blocking and water converging system for a head hub of a hydropower station, which is good in sand flushing effect and low in manufacturing cost. According to the sand-blocking and water-bundling system, an effective water diversion and sand prevention facility can be formed by the mesh screen type slag-blocking wall, the sand-blocking ridge, the water intake and the sand flushing gate, and the system is suitable for being applied to a hub at the head of a hydropower station for water diversion and sand prevention, and is particularly suitable for being applied to silt rivers with high steep ratio; due to the fact that the mesh screen type slag blocking wall is arranged, large-particle-size bed load can be effectively blocked, the mesh screen type slag blocking wall and the sand blocking ridge can effectively prevent silt from entering the water intake, it is ensured that the wa
