为解决高低水测流时过河索吊船挂鉤脫离的困难,我站制成了一种“低水挂鉤脫勾器”,如附图所示。它是由挂在过河索上的滑輪、升降鍊索、弯形鈎和地錨环組成。在低水測流时,将弯形鉤和地錨环如附图安装 In order to solve the difficulty of hooking and disengaging the river and gondola when measuring the water level, I made a “low-water hook-off device”, as shown in the attached drawing. It is linked by the pulley on the river, lifting chain, curved hook and anchor ring composition. In low water flow, the curved hook and anchor ring installed as shown in the drawings
