Description

Technical Field

[0001] The invention relates to the technical field of navigation buildings, and in particular to a docking-free rapid navigation ship lift and a working method thereof. Background Art

[0002] A ship lift is a navigation structure in a river that uses a mechanical device to lift ships to overcome the concentrated water level difference in the waterway. Compared with a lock device with the same function, it shortens the time for ships to pass through the dam, improves navigation efficiency, and saves energy and water resources under the condition of basically the same investment scale.

[0003] At present, the ship lifts studied and built at home and abroad can be divided into two types according to the ship transportation method: dry transportation and wet transportation; according to the ship transportation track, they can be divided into two types: vertical ship lift and inclined ship lift. Among them, the vertical wet transportation ship lift is widely used in ship lift projects at home and abroad because it can easily adapt to the changes in upstream and downstream water levels. Vertical wet transportation ship lifts can be divided into several types according to the lifting device, such as wire rope winch type, gear rack climbing type, hydraulic ship lift, etc. The wire rope winch ship lift is a type of ship lift that is widely used at home and abroad. It consists of a ship holding compartment, a main lifting system, a counterweight, etc. The counterweight is used to balance the weight of the ship holding compartment and the water in the compartment.

[0004] Regardless of the type of the above-mentioned ship lift, it must go through three processes of docking, lifting (or lowering) and docking to achieve navigation. For example, the patent application with publication number CN110374079A discloses a vertical ship lift docking device and method. Even if the structure of the docking device is simplified and the docking process is simplified, the time used for the two docking processes still accounts for more than half of the time for one lock. Therefore, the above-mentioned ship lift is mainly used to solve the problem of high dam cargo navigation. For the case of concentrated water level difference below 20mm, from the perspective of navigation efficiency, the ship lock has a greater advantage than the ship lift. With the development of domestic water transport engineering construction and the need for low carbon and environmental protection, the ship lift still needs to further improve its navigation efficiency while maintaining its water-saving and energy-saving characteristics. Especially for the case of low concentrated water level difference, how to reduce the docking time of the ship lift is an important issue in the industry. Summary of the invention
