The invention provides a river sluice structure for an urban water conservancy project, and relates to the technical field of water conservancy projects. The river sluice structure aims at solving theproblems that most existing river sluices are of knife switch type structures and are straight up and down, a traction mechanism is needed for continuous traction when an existing river sluice is open, and fatigue of the traction mechanism is easily caused; that in urban water conservancy projects, a straight up and down mode requires that a dam body is high and the mode is not suitable for an urban environment; and that a push type gate is large in stress and high in load on a driving mechanism, and meanwhile, a horizontally-pushed gate is prone to accumulating sludge in the long-time use process. The river sluice structure comprises a river sluice main frame body, and two symmetrical gate frames are fixedly mounted on the side wall of the front end of the river sluice main frame body. Due to the fact that vertical rail grooves parallel to short plate parts are formed in the rear ends of the inner walls of left side plates and right side plates of the gate frames, stress of a gate plate can be shared conveniently, downstream fishes can be prevented from swimming back to the upstream in the water discharging process, and loss is reduced especially for fish schools cultivated in aregion.
本发明提供一种城市水利工程用拦河闸结构，涉及水利工程技术领域，以解决现有的拦河闸多为刀闸式结构，直上直下的方式，在开放式需要牵引机构持续牵引，从而易造成牵引机构的疲劳，而在城市水利工程中，直上直下的方式要求坝体较高不适应于城市环境，而推式的闸门受力较大，对驱动机构负荷较高，同时平推的闸门易在长时间的使用过程中积攒淤泥的问题，包括拦河闸主架体；所述拦河闸主架体的前端侧壁上固定安装有两个对称的闸门架。本发明中由于闸门架左右侧板的内壁后端处开设有与短板部分相互平行的竖轨槽，以便于分担闸门板的受力，并且还可在放水过程中防止下游的鱼类回游到上游，尤其针对区域养殖类的鱼群，减少损失。
