Siltation-preventing water intake facility achieving automatic flood prevention and pollution discharge
The invention discloses a siltation-preventing water intake facility achieving automatic flood prevention and pollution discharge. The siltation-preventing water intake facility comprises a sand flushing slope, an overflow dam, a water collection groove and a setting basin. The sand flushing slope is arranged between connected mountains. A flood-preventing dam is arranged on the left side of the sand flushing slope, the overflow dam is arranged on the right side of the sand flushing slope, a sand turning nozzle is arranged between the sand flushing slope and the flood-preventing dam, the water collection groove is formed in the sand flushing slope in the water flow direction and matched with the sand flushing slope in a bearing mode, an overflow slope is arranged in the direction, parallel to the sand flushing slope, of the water collection groove, the right side of the water collection groove is provided with the overflow dam, the left side of the water collection groove is led to a residue filter bed, the residue filter bed is provided with an overflow groove in the water flow direction and matched with the overflow groove in a bearing mode, a water stop dam is arranged at the front end of the overflow groove, the overflow groove is connected with the setting basin, and the setting basin is provided with a water intake gate and a sand discharge gate. The water intake problems of a mountain river hydropower station, a tap water plant and farm irrigation are fundamentally solved, and the purposes that siltation and blockage are never caused on a water intake dam in the flood period, and natural water intake is achieved in the drought period are achieved.
