Eccentric bearing radial gate for water conservancy and hydropower engineering
The invention discloses an eccentric support radial gate for water conservancy and hydropower engineering, which comprises a radial gate leaf, a support arm, a support hinge and a gate support point, and when the eccentric support radial gate is used for retaining water, a water pressure resultant force action line does not pass through the gate support point. When the gate closing force is insufficient, a gate supporting point is arranged above the direction of a water pressure resultant force action line; when gate closing force is abundant and gate opening force needs to be reduced, a gate supporting point is arranged below the direction of a water pressure resultant force acting line. On the premise that the requirement for gate closing force of the gate is met, the gate opening force of the gate can be effectively reduced through eccentric torque generated by water pressure.
本发明公开了一种用于水利水电工程的偏心支承弧形闸门，包括弧形门叶、支臂、支铰和闸门支承点，偏心支承弧形闸门在挡水时，水压力合力作用线不通过闸门支承点。当闸门闭门力不足时，采用闸门支承点在水压力合力作用线方向的上方；当闸门闭门力富裕，需要减小闸门启门力时，采用闸门支承点在水压力合力作用线方向的下方。在满足闸门闭门力要求的前提下，可以利用水压力产生的偏心力矩有效降低闸门的启门力。
