The invention belongs to the technical field of river channel dredging, and discloses a river channel dredging device for hydraulic engineering construction. The device comprises an extraction pipe; a mud pump is fixedly mounted on the top surface of the extraction pipe; connecting frames are fixedly mounted at the left and right ends of the extraction pipe; a liquid storage pipe is fixedly mounted at the other end of each connecting frame; a servo motor is fixedly installed on the top faces of the liquid storage pipes; and the output end of the servo motor is fixedly connected with a first ball screw in a sleeving mode. According to the river channel dredging device for hydraulic engineering construction, when the first ball screw moves downwards, liquid in the liquid storage pipes is pressed into an arc-shaped guide pipe; when an arc-shaped push block rotates downwards, two digging shells can be driven to be closed, so that mud is dug; and when the mud is cleaned, the contact position of the device and the mud is only the middle and the front and rear ends of the digging shells, so that the flowing and diffusion of the mud are effectively reduced, the thickness of the mud is prevented from being reduced, the proportion of river water in the excavated mud under the unit working condition is effectively reduced, and the working efficiency of the device is improved.
本发明属于河道清淤技术领域，且公开了一种水利工程施工用河道清淤装置，包括抽取管，所述抽取管的顶面固定安装有抽泥泵，所述抽取管的左右两端均固定安装有连接架，所述连接架的另一端固定安装有存液管，所述存液管的顶面固定安装有伺服电机，所述伺服电机的输出端固定套接有滚珠丝杠一。本发明通过滚珠丝杠一在下移时，将存液管内的液体压入弧形导管内，在弧形推块向下旋转时可以带动两个挖取壳闭合，从而对淤泥进行挖取，在清理淤泥时，装置与淤泥的接触位置只有挖取壳的中部和前后两端，从而有效的减少了淤泥的流动和扩散，避免淤泥的稠度变小，从而有效的减小了单位工况下挖取淤泥中的河水占比，提高了装置工作效率。
