Novel gate structure for water conservancy project

A novel gate structure for a water conservancy project comprises a gate lifting plate used for opening and closing a gate opening in a wall body and a fixed rack fixedly mounted on the wall body. The upper side of the gate lifting plate is fixedly connected with the lower end of a lifting drive threaded sleeve. An external thread is arranged on the outer circumferential face of the lifting drive threaded sleeve and used for being matched with an internal thread in a lower drive gear, and the lower drive gear is rotationally mounted in the fixed rack and engaged with a lower driving gear. The lower driving gear is driven by a lower drive motor fixedly mounted in a cavity of the fixed rack. An axially-extending sliding groove is formed in the inner circumferential face of the lifting drive threaded sleeve and used for being in sliding and circumferential fixed fit with a radial extending part in the axial direction, wherein the radial extending part is fixedly connected with the lower end of a threaded rod capa
