Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-line lock technology, specifically to a submerged water-saving double-line lock. Background Technology
[0002] Traditional ship locks are mostly single-line locks, where all upstream and downstream vessels pass through a single lock chamber, with water draining downstream, resulting in significant water waste. With the continuous development of shipping and a surge in cargo volume, modern ship locks are mostly double-line locks, consisting of a single line and a second line, allowing upstream and downstream vessels to pass through separately, greatly improving vessel throughput. However, double-line locks are larger in scale and hold more water, leading to even greater waste.
[0003] To reduce water waste and achieve water conservation, the utility model patent "A Water-Saving Lock" (patent number: CN201621444422.9) proposes a transverse connecting corridor between the side walls of the first and second lock chambers. Water can flow between the two chambers, allowing for mutual irrigation and drainage, thus achieving a certain water-saving effect. However, because the transverse connecting corridor is located on the side wall of the lock chamber, its bottom plate is higher than the lock chamber bottom plate, resulting in a high position. When water flows from the high-water-level lock chamber to the low-water-level lock chamber, it is equivalent to being forced into the low-water-level lock chamber from the side. The high transverse flow velocity directly impacts the sides of the vessels, causing significant fluctuations in the water level within the lock chamber, which is detrimental to vessel safety and the normal operation of the lock. This structure is particularly unsuitable for double-line locks designed for larger vessels with more complex lock chamber structures and water flow conditions. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a submerged water-saving double-line lock, which solves the problem of large water surface fluctuations caused by lateral water flow when the two lock chambers of a double-line lock are connected, which is detrimental to the safety of ships and the normal operation of the lock.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A submerged, water-saving double-line lock, the double-line lock comprising: a first-line lock chamber and a second-line lock chamber;
[0007] The first corridor is located inside the outer side wall of the first-line gate, and the second corridor is located inside the inner side wall of the first-line gate; the third corridor is located inside the inner side wall of the second-line gate, and the fourth corridor is located outside the outer side wall of the second-line gate.
[0008] The first corridor is connected to the first-line gate chamber, the second corridor to the first-line gate chamber, the third corridor to the second-line gate chamber, and the fourth corridor to the second-line corridor through multiple branch holes;
[0009] The first corridor is connected to the third corridor, and the second corridor is connected to the fourth corridor via U-shaped connecting corridors;
[0010] The middle section of the U-shaped corridor is equipped with two working gates and two maintenance gates, with the two maintenance gates located outside the two working gates.
[0011] Preferably, the extension directions of the first corridor and the second corridor are both parallel to the extension direction of the first gate chamber; the extension directions of the third corridor and the fourth corridor are both parallel to the extension direction of the second corridor.
[0012] Preferably, the U-shaped connecting corridor includes: a horizontal connecting corridor and a vertical shaft;
[0013] The two ends of the horizontal connecting corridor are connected to the corresponding corridors through vertical shafts extending upwards;
[0014] Two working gates and two maintenance gates are located in the middle section of the horizontal connecting corridor.
[0015] Preferably, the cross-sections of the horizontal connecting corridor and the vertical shaft are both rectangular.
[0016] Preferably, the bottom elevations of the first-line gate chamber and the second-line gate chamber are the same;
[0017] The top elevation of the horizontal connecting corridor is lower than the bottom elevation of the first and second gate chambers.
[0018] This invention provides a submerged, water-saving, double-line ship lock. Compared with existing technologies, it has the following advantages:
[0019] In this invention, when water flows between the lock chamber and the corridor, multiple branch holes are used to disperse the water flow, which can effectively reduce the lateral flow velocity and lateral impact force. When water flows between the two lock chambers, two U-shaped connecting corridors that connect the first and third corridors and the second and fourth corridors are used as channels. The two U-shaped connecting corridors are staggered, but their shape, specifications and length are the same. This can not only speed up the water flow exchange speed between the two lock chambers, but also ensure that the water flow in the two U-shaped connecting corridors has the same time and distance, thus meeting the synchronization requirement. The water level in the two lock chambers rises and falls synchronously, the water surface is stable and the fluctuations are small, which is conducive to the safety of ships and the normal operation of the lock.
