Capsizing-resistant hydraulic power type ship elevator with stable balanced hydraulic driving system

Abstract

The invention provides a capsizing-resistant hydraulic power type ship elevator with a stable balanced hydraulic driving system. The ship elevator comprises a ship bearing compartment arranged in a lock chamber, a mechanical lifting system and the stable balanced hydraulic driving system, wherein the mechanical lifting system and the stable balanced hydraulic driving system are connected with the ship bearing compartment. The stable balanced hydraulic driving system comprises vertical shafts, float bowls arranged in the vertical shafts, a main water conveying pipe with a water conveying valve, and a plurality of branch water pipes with lower ends connected with the main water conveying pipe. Each branch water pipe is formed by a straight pipe of the lower portion, a corner pipe and / or a branch pipe in the middle, and a straight pipe of the upper portion, wherein the water outlet end of the straight pipe of the upper portion is arranged at the bottom of the corresponding vertical shaft, and an energy dissipater is arranged at the water outlet end of the straight pipe. All the vertical shafts are connected through a water level balance gallery. The ship elevator is characterized in that the stable balanced hydraulic driving system further comprises first resistance balancing parts arranged at the corners of the branch water pipes, or / and second resistance balancing parts arranged on the branch pipes, a circumferential direction reinforcing ventilating mechanism arranged in front of the water conveying valve of the main water conveying pipe, and a pressure stabilizing and vibration damping box arranged behind the water conveying valve of the main water conveying pipe. The ship elevator has a high capsizing-resistant ability.

Description

technical field [0001] The invention relates to a hydraulic ship lift, in particular to a hydraulic ship lift with a stable and balanced hydraulic drive system and anti-overturning capability, which belongs to the field of navigable buildings. Background technique [0002] The ship lift has the advantages of short dam crossing time, large water head, small investment and water saving, and has been widely used in high dam hubs with navigation requirements at home and abroad. The hydraulic ship lift is a new type of ship lift. On both sides of the lock room containing the ship-holding compartment, a plurality of shafts that can be filled and discharged are separated from the lock room and communicated with each other. Set up buoys, multiple buoys are connected to multiple parts of the ship-holding box through corresponding steel ropes, reels, and pulleys (that is, multiple lifting points are formed on the ship-holding box), when the vertical shaft is filled with water, the buo...

AI Technical Summary

Problems solved by technology

In order to reduce the initial value of the tilting moment of the ship, reduce the water level difference in the shaft and the fluctuation of the operating speed of the ship, reduce the uneven load of the hydraulic drive system on the ship and the disturbance of the water in the ship, and solve the problem of valve cavitation, cavitation, etc. The slow lifting speed and low efficiency of the ship lift caused by hydraulic problems such as vibration provide a guarantee for the safe, stable and efficient operation of the hydraulic ship lift
