Hydraulic ship-lifting system

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 specifically relates to a water conservancy ship lifting system. Background technique [0002] Ship lifts and ship locks are important components of water conservancy hubs. The ship lift and ship lock of the water conservancy hub are responsible for the transportation of ships across the dam. Therefore, the function of ship lifts and ship locks directly affects the functions and economic benefits of the water conservancy hub. The five-level ship locks and the ship lift under planning and construction of the Three Gorges Project are the largest and most advanced engineering projects in the world, and are of international advanced level. [0003] The two main economic indicators of the ship lock are the tonnage of the ship passing the dam and the time of the ship passing the dam. The designed annual transportation capacity of the Three Gorges Ship Lock is 50 million tons, which can meet the require...

AI Technical Summary

Problems solved by technology

The designed annual transportation capacity of the Three Gorges Ship Lock is 50 million tons, which meets the short-term and long-term shipping requirements of the Yangtze River (looking at it now, it cannot meet the requirements)

Because of its small dam crossing capacity, it cannot play the backup role that the five-stage ship lock needs to supplement due to accidents or insufficient maintenance capacity.
