Lifting type water conservancy gate equipment reliable in operation

Lifting type water conservancy gate equipment reliable in operation comprises a gate lifting plate (5) used for opening and closing a sluice gate (15) between walls (1), and a fixed rack (2) fixedly mounted on the walls (1). The upper side of the gate lifting plate (5) is fixedly connected with the lower end of a lifting-driving threaded sleeve (44), an external thread is arranged on the outer circumferential face of the lifting-driving threaded sleeve (44) and used for being matched with an internal thread of a lower driving threaded part (41) which is rotatably mounted in the fixed rack (2) and driven by a lower driving worm (43), and an axial-extending sliding groove (40) is formed in the inner circumferential face of the lifting-driving threaded sleeve (44) and used for being matched with a radial extending part (35) in axial-sliding and circumferential-fixing modes; and the radial extending part (35) is fixedly connected with the lower end of a threaded rod (34) which can penetrate through an inner cavit
