Anti-corrosion gate

The utility model discloses an anti-corrosion gate which comprises a gate leaf structure, a supporting arm structure, a supporting hinge structure and a water seal structure. One side of the gate leaf structure is symmetrically connected with the support arm structures, the support arm structures are arranged to be A-shaped, and one sides of the support arm structures are provided with the support hinge structures; a water seal structure is arranged on the periphery of the gate leaf structure, and one leg of the supporting arm structure is of a detachable structure. The device is simple in structure, the interior of the device can be well subjected to internal anti-corrosion treatment at the beginning of production and manufacturing, a structure body formed after treatment still has enough strength and is convenient to maintain, and the defect that corrosion prevention of the interior of a hydraulic steel gate bearing main structure is difficult is overcome. 本实用新型公开了一种防腐闸门，包括门叶结构，支臂结构，支铰结构，水封结构；在门叶结构的一侧对称连接设置
