The steel dam is composed of gate leaf, embedded parts, bottom shaft, crank arm, door partition device, hydraulic hoist, etc.
The operation mode of steel dam gate is dynamic water opening and
closing, which can be partially opened. A set of hydraulic headstock
gear is set on both sides of the gate to drive the crank arm of the
bottom shaft to move, which is the lifting and horizontal movement of
the gate and the opening and closing of the gate.
The gate hinge is cylindrical hinge, and the material is zg310-750, The
shaft sleeve adopts zqa9, and the hinge bearing adopts the joint
bearing. The hinge is the rotation center of the gate leaf when opening
and closing. The supporting hinge fixing part is fixed on the bottom
plate by the anchor bolt, and the movable part is connected with the
gate leaf structure by the bolt. It bears the external forces such as
the total water pressure, the weight of the gate leaf and the opening
and closing force during the opening and closing process. It is the key
component of the flap gate.

The maximum load of the hinge should occur when the gate is just opened.
The external forces such as the water pressure of the gate, the lifting
force and the dead weight of the gate are all borne by the hinge. Each
gate has multiple hinges, which are distributed in different positions
according to the width of the orifice.
