Problems solved by technology

The hydraulic floating torque balance weight ship lift has the advantages of safety, reliability, simple structure, and easy control. However, since the main driving force for driving operation comes from the buoyancy of the buoy, the cross-sectional size of the buoy must be large enough to provide Sufficient buoyancy overcomes the buoyancy generated by the launch of the ship box, resulting in a larger shaft size and a more complex civil structure. Due to the characteristics of the water body, fluctuations in the water level of the shaft are unavoidable, which is unfavorable for the smooth operation of the buoys and the synchronous rise and fall of the water levels of each shaft. The hydraulic problems of water pipelines are also more complicated

Embodiment Construction

[0018] Such as figure 1 As shown, the hydraulic lifting ship lift includes a ship bearing box, a reel, a movable pulley, a wire rope, a shaft, a buoy, etc. By adding a seal 3 between the buoy 1 and the shaft 2, the buoy becomes a piston, passing the upstream and downstream water head The pressure generated between the buoy and the vertical shaft drives the lifting operation of the ship's compartment 4 . The weight of the piston cylinder 1 is equivalent (or theoretically equal) to the weight of the vessel 4, and the product of the cross-sectional area and the head difference between upstream and downstream is equivalent to the volume of water carried by the vessel 4 (or theoretically equal). The piston cylinder 1 is connected with the movable pulley, and is connected with the ship-bearing box 4 through the steel wire rope 6 moving on the movable pulley. A sealing ring 3 is arranged around the piston cylinder 1, and the weight of the piston cylinder 1 is equivalent to the total...

Abstract

The invention provides a hydraulic ship elevator. The ship elevator comprises a ship chamber, a reel, a traveling block, a steel rope and a buoy, wherein the buoy is connected with the traveling block and is connected with the ship chamber through the steel rope which moves on the traveling block. The ship elevator is characterized in that a seal is arranged between the buoy and a vertical shaft, and the buoy becomes a piston, so that a pressure generated due to the differences between water levels of an upper reach and a lower reach drives the ship chamber to raise and fall. The ship elevator has the advantages of: 1, greatly reducing the size of the vertical shaft and the project investment by using the differences between the water levels of the upper reach and the lower reach and improving the structural safety of a tower of the ship elevator and facilitating the arrangement of the tower due to the reduced diameter of the vertical shaft; 2, smooth and reliable operation which ensures the smooth lifting of the ship elevator; and 3, easily ensuring the synchronous raising and falling of the water level in the vertical shaft and the safe and reliable operation of the ship elevator.

Description

technical field [0001] The invention relates to water conservancy and hydropower station foundation construction projects, in particular to a hydraulic lifting ship lift used for navigating high dams in inland rivers. Background technique [0002] In order to effectively use water resources and use the drop of rivers to obtain clean renewable energy, humans have built numerous dams and hydroelectric power projects. With the rapid development of hydropower projects, hydropower projects cover almost all rivers in China, including some shipping channels. To build a hydropower station, it is necessary to build a dam on the natural river to intercept the water flow and generate electricity. The direct passage of ships, so the power station built on the channel must be equipped with navigable dam buildings while building barrage dams. [0003] At present, the conventional ways of navigating through the dam include ship locks and ship lifts. The main types of ship lifts currently ...
