Problems solved by technology

Although this device improves the balance control ability of the ship lift, it greatly increases the construction cost of the ship lift; the device only sets the water inlet valve and the drain valve at the connecting pipe, which makes these valves vulnerable to cavitation The service life is shortened due to the impact, and it is more difficult to replace these large valves

Embodiment Construction

[0016] exist figure 1 And in Fig. 2, dam (1) and reservoir (2) are built in river (3), and ship sails into reservoir (2) from river (3) through dam (1), or sails into from reservoir (2) Rivers (3). The ship-bearing box (4) is a place for parking ships. It is a box-shaped structure filled with a certain amount of water, and its draft meets the draft requirements of various ships. After opening the sealed door, the ship can enter and exit freely. The bottom of the ship-bearing compartment (4) is equipped with track wheels (12), and under the support of the track wheels (12), the ship-bearing compartment (4) can move on the track (5). The track (5) is a steel rail, arranged along the vertical direction of the dam (1), and the foundation below the track (5) is a reinforced concrete structure. The shaft (6) is a reinforced concrete structure, which can be built in the reservoir (2) or on the bank of the reservoir (2). One end of the steel wire rope (7) is connected and fixed wi...

Abstract

The invention relates to a new ship high-efficiency over-dam device, which comprises: a ship support bank, a rail, an upright well, a torque balance weight, a coiling cylinder, a crown block, a steel wire, a gate, a sealing device, an inlet/outlet tube, and an inlet/outlet water valve. The invention utilizes the float and gravity to quickly lift and fall the ship on the rail via ship support bank. The invention can increase the over-dam efficiency, with high stability and reliability.

Description

technical field [0001] The invention relates to the navigation technology of river ships in water conservancy and hydropower engineering facilities, and specifically provides a novel high-efficiency dam crossing device for ships. Background technique [0002] With the rapid development of my country's social economy, more and more water conservancy and hydropower projects are erected in rivers. These numerous water conservancy and hydropower projects, on the one hand, play a very important role in the development and construction of industry, agriculture and electric power industry, on the other hand, they also bring inconvenience to the navigation of ships. In order to keep the ships in the big rivers unimpeded, ship locks or ship lifts are usually built at home and abroad at present. The ship lock is composed of a lock chamber and upstream and downstream gates. By filling and draining the lock chamber, the elevation of the ship entering the lock ch...
