浙江省庆元县水工器材厂新近发明了一种一改历来传统上下移门型的升降式水闸为卧水式人字形水闸,经1998年11月12日在浙江省水利科学研究院进行模型演示和考核答辩,获得了该院资深专家和省水利厅有关领导的一致好评.认为:这是一个新的发明,构思符合力学原理,巧妙、合理地利用水力学效应来实现其蓄排水功能,并对其如何付诸实施应用和造价及附件配合等方面提出了建议和指导性意见.将它称为人字形水闸是因为这种水闸有两扇门板,它们在水流前进方向的纵剖面上形成一个人字形机构,挡水前闸板则由支撑它的后闸板一端以导轮顶住其背面,并可在其背面的导轨中滑动,前闸板的下端和后闸板的另一端又分别铰接于闸底可以自由转动的横向铰轴上,前闸板下方设有泄水孔,后闸末端铰接轴下设有排水道和出水阀门. 这种新型水闸使用时控制极为方便:要放水时,只要将后闸板末端铰接轴下的排水阀门打开,闸板下水室中的水压降低,人字形闸门因自重和上下水压差而下降,导轮也在导轨中向 Qingyuan County, Zhejiang Province, hydraulic equipment factory recently invented a change has traditionally shifted down the gate type of water gate for the lying water herringbone sluice, on November 12, 1998 in Zhejiang Province Institute of Hydraulic Research model Demonstration and assessment reply, won the hospital senior experts and provincial water conservancy department leaders agree that: This is a new invention, the concept conforms to mechanics, clever and rational use of hydraulic effects to achieve its water storage and drainage functions, And put forward suggestions and guidance on how to put it into practice, cost and accessories, etc. It is called the herringbone sluice because the sluice has two door panels that form a longitudinal section in the direction of water flow Herringbone body, the water gate is supported by its front end of the rear gate with a guide wheel to withstand the back, and can slide in the back of the guide rail, the lower front gate and the other end of the rear gate separately Hinged to the bottom of the hinges can freely rotate on the horizontal hinge shaft, the front gate has a drain hole below the hinges at the rear end of the hinge shaft has a drain and outlet valve. The use of this new type of sluice control extremely convenient: Water, as long as the rear gate hinged shaft under the drainage valve is open, the water pressure in the raft lower chamber, the herringbone gate due to weight and water pressure drop down, the guide wheel is also in the rail to the
