The transverse beam 11 and the vertical beam 12 are arranged on the backwater side of the panel 13, and the guide plate 14 is arranged at the bottom of the panel 13. The top of the panel 13 and the bottom of the guide plate 14 are smooth curved surfaces. In a specific design, the contact part between the door leaf structure and the water flow is generally rounded.

[0029] The support arm 2 is fixed on the backwater side of the gate leaf 1. The support arm 2 is hinged to the pier 3. The gate leaf 1 is automatically opened and closed with the help of water pressure and the deadweight of the gate. The two ends of the gate hoist 4 are respectively hinged to the support arm 2 and the pier 3. In special working conditions, the gate leaf 1 is assisted by the gate hoist 4 to open and close.

When the distance a between the axis of the support arms and the outer edge of the gate leaf is 0.207 times the total width of the gate leaf l+2a, the positive and negative bending moments of the gate leaf transverse beam are equal, the height of the transverse beam is the lowest, and the transverse beam uses the least material.
