Abstract

The invention relates to a hydraulic ship-lifting system, wherein a sluice chamber is internally provided with a floating ship cabin; a sluice chamber water-filling and discharging system comprises an upstream water supplying tank, below which a water-filling valve chamber is connected; the water-filling valve chamber is internally provided with a first ball valve set and a first flat valve set; the water-filling valve chamber is communicated with a water-filling passage through the first ball valve set and the first flat valve set; the water-filling passage is communicated with the sluice chamber; the other side of the sluice chamber is provided with a discharging passage; the discharging passage is communicated with a tailrace tank through a second ball valve set and a second flat valve set in a drain valve chamber; the floating ship cabin comprises floating barrels which are arranged at two side walls of the sluice chamber by using a guide device; bottoms of the two floating barrels are connected with a current-stabilizing grid plate; and each floating barrel is internally provided with a power device. According to the hydraulic ship-lifting system, the water level lifting speed of the sluice chamber is improved, so that the water level lifting speed of the sluice chamber is controllable, constant and steady; and the speed can be reduced from the maximum to zero, so that the running time is greatly shortened.

Description

technical field

[0001] The invention belongs to the field of water conservancy, and in particular relates to a water conservancy ship lift system. Background technique

[0002] Ship lifts and ship locks are important components of water conservancy projects. The ship lift and ship lock of the water conservancy project are responsible for the transportation of ships across the dam. Therefore, the function of the ship lift and ship lock directly affects the function and economic benefits of the water conservancy project. The completed five-level ship lock and the planned ship lift of the Three Gorges Water Conservancy Project are the largest and most advanced engineering projects in the world, with international advanced level.

[0003] There are two main economic indicators of ship locks, one is the tonnage of ships crossing the dam, and the other is the time of ships crossing the dam. The Three Gorges Ship Lock has a designed annual transportation capacity of 50 million t...
