Stable and reliable lifting type water conservancy gate structure

Abstract

A stable and reliable lifting type water conservancy gate structure 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 cavity of the lifting-driving threaded sleeve (44).

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to a stable and reliable lift-type water conservancy gate structure. Background technique [0002] The lifting of the gate plate can realize the opening and closing control of the gate. In the field of water conservancy, screw lifting is often used to lift the gate plate. [0003] In order to achieve the required height for the lift of the gate plate, the height of the screw rod must have a size that matches the lift height of the gate plate. This makes the screw height or the overall length dimension larger, resulting in an increase in the overall size of the equipment, which results in an increase in cost and difficulty in maintenance. However, if the screw rod is protruded separately from the whole device casing, the screw rod will be exposed, which will cause the screw rod to be damaged by the external environment and affect the service life. Moreover, it affects th...

This makes the height of the screw or the overall length larger, resulting in an increase in the overall size of the equipment, which results in increased costs and difficulties in maintenance

However, if the screw rod is protruded separately from the whole equipment shell, the screw rod is often exposed, which will cause the screw rod to be damaged by the external environment and affect the service life.

Moreover, it affects the appearance of the overall equipment and is difficult to maintain
