Axis-around counter weight type gate for overflow dam and using method of axis-around counter weight type gate
The invention provides a spool counterweight type gate for an overflow dam, which comprises a bearing steel gate, a counterweight steel block is placed on the bearing steel gate, an opening and closing mechanism is arranged above the bearing steel gate, a winch room is arranged on the upstream side of the opening and closing mechanism, and a traffic bridge is arranged on the upstream side of the winch room. The bearing steel gate and the counterweight steel block are parallel to the axis of the dam and are arranged between the two gate piers, a rotating shaft is arranged above the bearing steel gate, two hinge supports are respectively arranged at gate feet on two sides of the bearing steel gate, the length of the rotating shaft is the same as the width of the bearing steel gate, and the rotating shaft is positioned right above the top of the overflow dam. The problem of sluice pier towering caused by too long sluice piers in a traditional overflow dam can be solved, the anti-seismic performance of the dam is greatly improved, the material cost can be greatly saved through the design of the shorter sluice piers, the overflow dam traffic bridge and the dam crest road of the water retaining dam are connected in a straight mode, the design of the overflow dam section is simplified and more reasonable, and the anti-seismic performance of the dam is improved. And the design and construction difficulty is reduced.
本发明提供一种用于溢流坝的绕轴配重式闸门，包括承载钢闸门，所述承载钢闸门上放置有配重钢块，所述承载钢闸门上方设有启闭机构，启闭机构上游侧设有卷扬机房，所述卷扬机房上游侧设有交通桥，所述承载钢闸门和所述配重钢块平行于坝轴线设置在两闸墩中间，所述承载钢闸门上方设有转动轴，所述承载钢闸门两侧门脚处分别设置两个铰接支座，所述转动轴的长度与承载钢闸门的宽度相同，位于溢流坝顶的正上方。本发明可避免传统溢流坝中由于闸墩过长所带来的闸墩高耸问题，大大的提高了大坝的抗震性能，更短的闸墩设计也可大大节约材料成本，溢流坝交通桥和挡水坝坝顶公路顺直连接，简化溢流坝段的设计并且使其更加合理，降低了设计和施工难度。
