1965年,我们为北庙水库设计、制造出一鹰嘴式杠杆机构,用以起闭检修闸门。它既使检修闸门在一定水头下动水关闭,以便检遂洞和工作闸门;又可不设置构造复杂的充设备,仅用手拉葫芦通过杠杆即可获得较大初始起吊力,将在设计水头作用下的检修闸开起一个小开度,待造成平压条件后,再将门全部开启。 In 1965, we designed the Bei Mia Reservoir to create an olecranon lever mechanism for starting and closing the inspection gates. It makes the maintenance gate closed under a certain head of water in order to check the tunnel and work gate; also do not set the complex structure of the charge equipment, only by hand chain hoists can get a larger initial lifting force will be designed head Under the action of the gate opened a small opening, to be flat pressure conditions, and then all the doors open.
