Fixed shaft supporting device suitable for rotary gate and gate mechanism

The invention provides a fixed shaft supporting device suitable for a rotary gate and a gate mechanism and relates to the technical field of hydraulic engineering. The fixed shaft supporting device suitable for the rotary gate comprises shaft assemblies. Each shaft assembly comprises a shaft body and a bearing. One ends of the shaft bodies are fixedly connected to a gate pier while the other endsof the shaft bodies are connected to the bearings, and the bearings are connected to the gate. The gate mechanism comprises the gate and the fixed shaft supporting device. In an operating process of applying the fixed shaft supporting device suitable for the rotary gate and the gate mechanism, the gate rotates relative to the shaft bodies, the shaft bodies are stationary relative to the gate pier,the gate pier is unlikely to leak water, and the bearings are conveniently maintained and replaced. 本发明提供了一种适应旋转式闸门的定轴支承装置及闸门机构，涉及水利工程技术领域。所述适应旋转式闸门的定轴支承装置包括：轴组件，所述轴组件包括轴体和轴承，所述轴体的一端用于与闸墩固定连接，所述轴体的另一端与轴承连接，所述轴承用于与闸门连接。所述闸门机构包
