Embodiment 1

[0030] This embodiment is a 1000t large-scale vertical ship lift on the Jinsha River in my country. The ship lift is a rack and pinion climbing fully balanced type, and the docking locking mechanism bears the unbalanced load caused by the change of the water depth of the cabin by ±40cm. The ship lift ship The design water depth of the cabin is 3.0m, and the draft of a 1000t class single ship is 2.0m, while the size of a 1000t class single ship is 58m×10.8m×2.8m (length×width×draft), that is, the draft of the ship is 2.8 when loading 1000t m, and according to the 2.0m draft standard of the ship lift, the ship only loads about 400t, and the shipping efficiency of the ship is greatly affected, but there has been no suitable method to improve the draft standard of the ship.

Abstract

A ship lift navigable ship draft standard improving method actively utilizes a ship lift docking locking mechanism to bear large unbalanced load, when a ship chamber is docked, the threshold water depth of a ship lift lock head working door is increased, meanwhile, the docking elevation of the ship chamber is reduced to make the ship chamber water level lower than an approach channel water level,and the ship chamber is filled with water through a ship chamber water depth adjusting device to make the water level flush with the approach channel water level, so after docking, the water depth ofthe ship chamber is increased, conditions are provided for improving the draft standard of the ship, and load change caused by increase of the water depth of the ship chamber is borne by the docking locking mechanism; when docking of the ship chamber is relieved, the ship chamber is drained through the ship chamber water depth adjusting device, and the water depth of the ship chamber is reduced toa designed water depth, so it is guaranteed that the lifting load of the ship lift is not changed, and normal lifting operation is not affected. The method is ingenious and easy to implement, and theship draft standard improving effect is remarkable.

Description

technical field [0001] The invention relates to a method, which is a method for raising the draft standard of a navigable ship by a ship lift, and belongs to the field of high dam navigation. Background technique [0002] Navigational structures are important node projects for inland water transport, mainly including ship locks and ship lifts. Ship locks are mainly used when the water level difference between upstream and downstream is less than 40m, while ship lifts are mainly used for high dam navigation. In recent years, my country's ship lifts have developed rapidly, and a number of large-scale vertical ship lifts have been built and put into operation one after another. The representative ones include: the Shuikou 2×500t class wire rope hoist ship lift that was put into operation in 2007, and the ship lift that was put into operation in 2014. The Pengshui 500t-class wire rope hoisting ship lift, the Three Gorges 3000t-class rack and pinion climbing ship lift that was put...
