Hydropower floating quick vertical ship lift

Abstract

The invention relates to a hydraulic floating type fast vertical ship lift, which belongs to the technical field of ship lift. The ship lift which is provided by the invention substantially comprises a balanced system, a hoisting system and a mechanical synchronous system. The working principle is that the total weight of a surge drum balances the total weight of a ship chamber, a lifting vertical shaft is filled with water or the water in the lifting vertical shaft is discharged through operating a feed valve or a drain valve, thereby achieving the purpose of changing the weight of the lifting surge drum, and overcoming the frictional resistance and impelling the ship chamber to lift. The hydraulic floating type fast vertical ship lift is capable of replacing locks flights or a wire rope hoisting ship lift to complete a lifting ship operation, thereby being capable of saving massive operation water. The lifting speed is rapid, massive time is capable of being saved when a ship crosses a dam, complex making and installment process of a miter gate and complex construction of a water-carriage system and a drainage system of a lock chamber are avoided, thereby saving massive project investment. The workload of repair and maintenance is small, and the cost is low.

Description

technical field [0001] The invention relates to a ship lift, in particular to a hydraulic floating fast vertical ship lift which utilizes changes in water levels to complete ship lift operations. Background technique [0002] The applicant applied for an invention patent named "Hydraulic Floating Torque Balance Weight Ship Lift" on May 18, 1999. The patent number is 99116476.8, and the authorized announcement number is CN1240859. With a certain weight of water, the balance weight moves in the shaft, and the shaft is connected through the connecting pipe, and the lifting operation of the ship can be controlled by filling and draining the shaft to complete the lifting operation. The ship lift can synchronize the lifting points of the ship lift Lifting, safe operation and high reliability, it is very convenient to realize the water-type docking between the ship receiving box and the downstream. But still there is the shortcoming that operation water consumption is bigger in th...

AI Technical Summary

Problems solved by technology

However, there is still the disadvantage that the operating water consumption is relatively large during the working process.

[0003] The fully balanced vertical ship lift with wire rope hoisting is also widely used in my country, but its safety device cannot cope with the extreme accident state that the water body in the ship tank is completely empty.
