QI型曲线铰座水力自控问门,在1985年1。月由湖南省水利水电厅通过了技术鉴定。但限于条件,定量观测和模拟均不够系统,为了弥补这一不足,于198脾9月至12月委托水利电力部、交通部南京水利科学研究院作了验证性的试验,证明QI型闸门突破了拍打失稳问题。南科院试验报告中指出:QI型闸门属复合运动型轻便翻板闸门,采用椭圆形曲线铰座,铰位变化具有连续性,稳定性能好,在设计思思上有所创新。该型闸门在加设通气设施及「〕顶附加角铡的门型试验条件「,运转稳定,开关门过程均无撞击现象.当下游水深超过堰顶1.4-1.8米(试验门高为2米)范围内,闸门虽有慢晃动,但不连续,不随时间加剧,不撞击支墩,无拍打 QI-type curve hinge hydraulic self-control asked the door, in 1985 1. Month by the Hunan Provincial Department of Water Resources and Hydropower passed the technical appraisal. However, due to limited conditions, quantitative observations and simulations are not enough systems. In order to make up for this deficiency, a pilot test was commissioned by Ministry of Water Resources and Electric Power and Ministry of Communications of Nanjing Hydraulic Research Institute from September to December 1988. It proved that QI gate breakthrough Beat the problem of instability. South Institute test report states: QI-type gate is a composite sports lightweight flap gate, the use of oval-shaped curve hinges, hinges change with continuity, stability, and innovation in the design of thinking. This type of gate is fitted with a door type test condition of “Ventilation facilities” and additional “,”, stable operation and no collision during opening and closing process. When the downstream water depth exceeds the weir top by 1.4-1.8 meters (test door height is 2 meters ) Within the scope of the gate, although slow shaking, but not continuous, do not aggravate with time, do not hit the pier, no beating
