Hydraulic dam bottom hole desilting device
The invention provides a hydraulic dam bottom hole desilting device. The hydraulic dam bottom hole desilting device comprises a desilting barrel, a desilting pipe which communicates with the desiltingbarrel and a movable cover which is located in the desilting barrel. A desilting hole is formed in the dam surface of a hydraulic dam. The desilting barrel communicates with the desilting hole. The movable cover moves in the desilting barrel so as to cover the desilting hole or leave the desilting hole to make the desilting hole, the desilting barrel and the desilting pipe communicate. By means of the hydraulic dam bottom hole desilting device provided by the invention, the desilting barrel is connected to the desilting hole of the bottom of the dam surface, compressed air is injected into anairtight space through a first air inflation head, and the front cover can be pushed forwards to cover the desilting hole; compressed air is injected into an annular space through a second air inflation head, the front cover can be pulled backwards to leave the desilting hole, thus sandstone which is deposited at the bottom of water can be automatically discharged sequentially through the desilting hole, the desilting barrel and the desilting pipe, the structure is simple, the practicability is high, the desilting efficiency is high, the dam surface does not need to lie down, and the water flow is saved.
本发明提供了一种液压坝底孔排沙装置，包括排沙筒，与排沙筒连通的排沙管，位于排沙筒中的活动盖；所述液压坝坝面上开设有排沙孔，所述排沙筒和排沙孔连通，所述活动盖在排沙筒中移动以遮挡排沙孔或者脱离排沙孔以使排沙孔、排沙筒和排沙管连通。本发明提供的液压坝底孔排沙装置，将排沙筒连接在坝面底部的排沙孔上，通过第一充气头向密闭空间中注入压缩空气，可向前推动前盖遮挡排沙孔，通过第二充气头向环形空间中注入压缩空气，可向后拉动前盖脱离排沙孔，从而可使沉积在水底的沙石依次通过排沙孔、排沙筒和排沙管自动排出，结构简单，实用性强，排沙效率高，且无需坝面卧倒，节约了流水量。
