Abstract

The invention discloses a sand suction and sand discharge device in front of the water inlet tower of the flood discharge tunnel of a hydropower station, which is installed at the front of the flood discharge tunnel of the water inlet tower of the hydropower station, and is connected and fixed through the front platform of the water inlet tower and the gate pier of the flood discharge tunnel. It mainly includes a fork-shaped connection device, a suction and discharge device A sand pipe and a sand suction table, the sand suction and discharge pipe includes several sections of pipeline units whose diameters increase sequentially along the direction from the head to the tail, and the several sections of pipeline units are connected in sequence through hinged devices. The end is connected to the sand suction table, the end of the pipeline unit at the tail is connected to one end of the fork-shaped connection device, and the other end of the fork-shaped connection device is connected to the two openings of the flood discharge tunnel group through the n-shaped gate. The invention has the advantages of strong plasticity, wide application range, and easy implementation of engineering measures, and can realize clear water sand discharge and high water level sand discharge in front of the water inlet tower, and solve the silt caused by the collapse of sand and sand at the front of the water inlet tower and the opening of the flood discharge hole. blocking problem.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a suction and sand discharge device in front of the water inlet tower of a flood discharge tunnel of a hydropower station, which uses the natural head pressure of the reservoir of the power station to expand and extend the influence range of the flood discharge and sand discharge hole to realize the suction and discharge of sand in the power station. Suction and discharge of sediment in front of the water inlet prevents sediment deposition in front of the water inlet tower from collapsing the sediment in the high beach and deep groove and blocking the entrance of the flood discharge tunnel of the hydropower station. Background technique [0002] After the river water flows into the reservoir, the sediment carried in the water flow will continue to deposit due to the gradual decrease of the flow velocity, resulting in the continuous sedimentatio...
