Embodiment Construction

[0024] This embodiment is a cylindrical gate structure with a gate chamber, 6 water inlets are evenly arranged around the gate chamber, and the 6 water inlets are evenly distributed radially around the gate chamber, and the water inlets are from one end to the gate chamber. The connecting end of the chamber is arranged obliquely downward.

[0025] In this example, a water outlet vertically arranged and connected to the gate chamber is provided at the lower end of the gate chamber, and a smooth transition surface is formed on the lower inner wall of the gate chamber, between the water inlet and the water outlet below the gate chamber. The upper end of the gate chamber is provided with a gate well which is vertically arranged and communicated with the gate chamber below, and the lower end of the gate well is formed with a gate through hole with a diameter slightly smaller than the inner diameter of the gate well, and a ring of supporting steps is formed between the gate well and ...

Abstract

The invention relates to a cylinder type gate structure. The structure is a cylinder type gate structure for a vertical shaft intake used for solving the problem of uneven water load and decreasing hoisting capacity needed. The technical scheme of the structure is that the cylinder type gate structure is characterized in that the structure comprises a gate cavity; a plurality of water inlets are evenly mounted around the gate cavity, and communicated with the gate cavity; water inlets are mounted on the lower end of the gate cavity and communicated with the gate cavity; and a gate shaft is mounted on the lower end of the gate cavity and communicated with the gate cavity. The cylinder type gate structure belongs to the field of hydraulic steel gates.

Description

technical field [0001] The invention relates to a mouth barrel gate structure. It is suitable for the field of hydraulic steel gates. Background technique [0002] Most of the traditional plane gates or arc gates are characterized by blocking water flowing horizontally to the cavern. Huge unbalanced water load acts on the front side of the gate panel, and all the load is transmitted to the gate slot track structure through the supporting sliders arranged on the gate. The gate itself is mostly a beam-column welded structure, with a large dead weight, and the friction between the gate and the gate slot track is large, and the required opening and closing force is large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shaft type water inlet cylindrical gate structure to solve the problem of unbalanced water load and reduce the required opening and closing force in view of the above existing problems. [0004] T...
