Sand and stone discharging device for hydropower station
The sand and stone discharging device comprises an air storage bin, a sand and stone discharging pipe set and a sand and stone transferring mechanism, the bottom of the air storage bin is open, the air storage bin is used for being buried in a water body on the inner side of a dam body of the hydropower station, and the air pressure in the air storage bin divides the interior of the air storage bin into an air cavity located above the water surface and a water cavity located below the water surface; the inlet end of the gravel discharging pipe set communicates with the air cavity, a valve set is arranged on the gravel discharging pipe set, the outlet end of the gravel discharging pipe set is used for extending to the outer side of the dam body of the hydropower station, the valve set is used for preventing air pressure in the air storage bin from leaking, and the gravel transferring mechanism is arranged in the air storage bin. The sand and stone transferring mechanism is used for transferring sand and stone at the bottom of the water cavity into an inlet of the sand and stone discharging pipe set. According to the equipment, sand and stone are separated from a water body in the sand discharging process, the water body cannot be discharged in the sand and stone discharging process, and the technical problem that an existing sand and stone discharging device can discharge a large amount of water body when used is effectively solved.
本公开涉及一种水电站用排沙石装置，包括存气仓、排沙石管组和沙石转运机构，存气仓的底部敞口设置，存气仓用于埋设于水电站坝体内侧的水体内，存气仓内的气压将存气仓内部分隔为位于水面上方的气腔和位于水面下方的水腔，排沙石管组的入口端与气腔连通，排沙石管组上设置有阀门组，排沙石管组的出口端用于延伸至水电站坝体的外侧，阀门组用于防止存气仓内气压外泄，沙石转运机构设置在存气仓内，沙石转运机构用于将水腔底部的沙石转运至排沙石管组的入口内。该设备在排沙过程中将沙石与水体分离，排沙石的过程中不会排出水体，有效解决了现有的排沙石装置使用时会一同排出大量水体的技术问题。
