Water conservancy project drainage structure
The invention relates to the technical field of water conservancy project devices, in particular to a water conservancy project drainage structure. The flood discharge groove is formed in a dam body; the outer frame is embedded in the flood discharge groove, a plurality of groups of guide grooves are vertically formed in the inner wall of the outer frame, and a plurality of slots are formed in the bottom of the outer frame; a flashboard is connected in each group of guide grooves in a sliding manner, the bottom end of each flashboard can be embedded into one slot, the multiple flashboards are arranged downwards in a stepped manner in the water outlet direction, and a gap is formed between every two adjacent flashboards and is increased in sequence; the traction mechanism is used for simultaneously lifting the multiple flashboards and comprises a vertical first telescopic device, a hinge arranged on the outer frame and perpendicular to the flashboards and a plurality of supporting rods arranged in parallel, the bottom ends of the supporting rods are hinged to the top ends of the flashboards, the top ends of the supporting rods are connected with the outer frame through the hinge, and the supporting rods can rotate around the hinge; the top end of the first telescopic device is fixedly connected with the top end of the outer frame, and the bottom end is fixedly connected with the top of any flashboard; horizontal impact caused by water flow inertia can be relieved.
本发明涉及水利工程装置技术领域，具体涉及一种水利工程疏水结构。包括：设置在坝体上的泄洪槽；嵌设在泄洪槽中的外框，外框的内壁竖向设置有若干组导向槽，外框的底部设置若干插槽；每组导向槽内均滑动连接有一闸板，每个闸板的底端均可与一个插槽镶嵌，多个闸板沿出水方向阶梯向下设置，相邻的闸板之间具有间隔，且间隔依次变大；用于同时升降多个闸板的牵引机构，其包括垂直的第一伸缩装置，设置在外框上、与闸板垂直的铰链，以及多个平行设置的撑杆，撑杆的底端与闸板的顶端铰接，撑杆的顶端通过铰链与外框相连，撑杆可绕铰链转动，第一伸缩装置的顶端与外框的顶端固接，底端与任意一个闸板的顶部固接；本发明可减缓水流惯性造成的水平冲击。
