Description

Technical Field

[0001] The utility model relates to the technical field of ship lock water delivery systems, in particular to a vortex-eliminating ship lock. Background Art

[0002] Ship locks play a vital role in inland waterway navigation. Generally, ship locks are equipped with water channels, and the water inlet and outlet of the water channel are set on both sides of the gate. After the ship enters the lock chamber, the ship lock begins to discharge water. After the drainage is completed, the gate opens and the ship sails out of the lock. In order to shorten the time for ships to pass through the lock, improve the shipping capacity, and improve the water transfer efficiency of the ship lock, the most common and effective way is to increase the flow rate of the discharge water of the ship lock. When the flow rate of the discharge water increases, vortices are easily generated at the water inlet of the water channel. Such vortices will cause the gate of the ship lock to vibrate, affecting the durability of the ship lock structure and reducing the overall life of the ship lock. At present, a streamlined vortex-eliminating cover is used to eliminate vortices. The inner and outer surfaces of the cover body are concentric arc structures. Sealing plates integrally formed with the cover body are arranged at both ends of the cover. The cover is provided with columns, which are arranged on both sides of the water inlet of the water transfer channel. However, in this way, water enters the water transfer channel from all sides of the cover, and the water transfer efficiency is low and the time is long.

[0029] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0030] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0031] In order to solve the problem of low water delivery efficiency of ship locks in the prior art, the utility model provides a vortex-eliminating ship lock.

[0032] like Figures 1 to 3 as well as Figure 7 As shown, the vortex elimination ship lock includes a lock chamber and a vortex elimination member 40. The lock chamber includes a side wall 10 and a bottom layer 20, and the lock chamber is provided with a water inlet trough 30, and the side wall 10 is provided with a water inlet 31 of the water inlet trough 30, and the bottom layer 20 is provided with a water outlet 32 ​​of the water inlet trough 30. The vortex elimination member 40 includes a pillar 41 and a cover plate 42, the pillar 41 is arranged on the bottom layer 20, the pillar 41 is spaced apart from the side wall 10, and is arranged corresponding to the water inlet 31, the cover plate 42 is arranged on the top of the pillar 41, and a vortex elimination hole 421 is opened on the cover plate 42, and the cover plate 42 is adapted to the water inlet 31.

[0033] By setting up the vortex-eliminating member 40, the pillar 41 of the vortex-eliminating member 40 is set on the bottom layer 20 of the lock chamber, and the cover plate 42 is set on the top of the pillar 41; in the drainage stage, the water in the lock chamber enters the water inlet 31 along the four sides of the cover plate 42, the vortex-eliminating holes 421 on the top of the cover plate 42, and the gap between the pillar 41 and the side wall 10. The water in the lock chamber is diverted at the water inlet 31 and enters the water inlet trough 30 along multiple paths, which not only improves the efficiency of water delivery but also avoids the formation of vortex at the water inlet 31 to affect the durability of the ship lock. At the same time, the cover plate 42 has a small height in the vertical direction. Even if a ship passes by, it will not scratch the bottom of the ship, which has a higher safety.

[0034] In this embodiment, there is one support column 41 , and the support column 41 is disposed at the center of the cover plate 42 .

[0035] Specifically, the pillars 41 are connected and fixed to the cover plate 42. The cover plate 42 is a thin flat plate structure and a prefabricated structure. During construction, the cover plate 42 and the pillars 41 are connected by hoisting. Of course, the cover plate 42 can also be a structure cast on site.

[0036] Furthermore, the pillar 41 is connected to the bottom layer 20 by casting or detachable connection. Optionally, the pillar 41 is a reinforced concrete structure.

[0037] like Figures 1 to 2 As shown, the lock chamber further includes a flow-blocking structure 50 , and the water inlet 31 is provided with the flow-blocking structure 50 , and the flow-blocking structure 50 is provided corresponding to the support pillar 41 .

[0038] Specifically, the water inlet 31 is opened on the side wall 10 and the pillar 41 is arranged corresponding to the water inlet 31. The flow-blocking structure 50 divides the water inlet 31 into a first water inlet and a second water inlet. The water entering the water inlet groove 30 is diverted at the water inlet 31. The water flow velocity on both sides of the flow-blocking structure 50 is relatively large. The pillar 41 and the flow-blocking structure 50 are arranged on the same straight line. Through this arrangement, the water flow is divided into two when passing through the pillar 41, and enters the first water inlet and the second water inlet respectively, so as to achieve the effect of reducing the erosion of the pillar 41 by the water flow entering the water inlet groove 30, thereby improving the service life of the vortex eliminater 40.

[0039] Further, the flow blocking structure 50 is a flow blocking pier, which is streamlined as a whole to improve the service life of the flow blocking structure 50. Optionally, the flow blocking pier is a concrete structure, and the flow blocking structure 50 is cast at the water inlet 31. Optionally, a flow blocking structure 50 is also provided at the water outlet 32 ​​to facilitate drainage of the water outlet 32.

[0040] like Figures 4 to 7 As shown, the cover plate 42 includes a first cover plate 422 and a second cover plate 423 . The first cover plate 422 is fixedly connected to the support 41 . There are multiple second cover plates 423 , and the multiple second cover plates 423 are pivotally connected to the first cover plate 422 .

[0041] Specifically, the pillar 41 is connected to the center position of the first cover plate 422, the first cover plate 422 is rectangular, there are four second cover plates 423, the four second cover plates 423 are respectively arranged corresponding to the four sides of the first cover plate 422 and are pivotally connected, and the second cover plate 423 is also provided with a vortex elimination hole 421.

[0042] In this embodiment, the cover plate 42 has a first state and a second state. In the first state, the second cover plate 423 and the first cover plate 422 are on the same plane, and the water flows through the vortex elimination holes 421 on the first cover plate 422 and the second cover plate 423, and the water flows are divided into multiple small water flows. In this state, the area of ​​the cover plate 42 is larger and can adapt to the situation where a large vortex is generated at the water inlet 31. In the second state, the second cover plate 423 is folded downward relative to the first cover plate 422. At this time, the water flow passing under the cover plate 42 is diverted by the vortex elimination holes 421 on the second cover plate 423, thereby improving the vortex elimination effect of the vortex elimination member 40.

[0043] In another embodiment of the present application, Figure 8As shown, there are multiple pillars 41 , and the multiple pillars 41 are arranged at intervals on both sides of the water inlet 31 , and the multiple pillars 41 are all connected to the cover plate 42 .

[0044] Specifically, there are four pillars 41, which are arranged at intervals on both sides of the water inlet 31, and are respectively connected to the four corners of the cover plate 42. When draining water, the water flow rate entering the water inlet 31 is fast, and the water flow rate on both sides of the water inlet 31 is slow. The pillars 41 are arranged at this position to reduce the erosion effect on the pillars 41.

[0045] In another embodiment of the present application not shown in the figure, the water inlet 31 is provided with a plurality of flow-blocking structures 50, and the plurality of flow-blocking structures 50 are arranged one-to-one corresponding to the plurality of pillars. The water inlet 31 is divided into a plurality of narrower water inlets, and the plurality of pillars 41 are arranged at intervals to improve the supporting effect of the pillars 41 on the cover plate 42.

[0046] In the present embodiment, there are multiple water inlet grooves 30 and multiple vortex eliminating members 40 , and the multiple vortex eliminating members 40 and the multiple water inlet grooves 30 are arranged in a one-to-one correspondence.

[0047] Specifically, there are two water inlet grooves 30, which are respectively arranged in two side walls 10, and there are two vortex eliminating parts 40, which are respectively arranged at the water inlets 31 of the two water inlet grooves 30. In this embodiment, one of the two water inlet grooves 30 is provided with a flow blocking structure 50, and the vortex eliminating part 40 corresponding to the water inlet groove 30 is provided with a pillar 41, and the pillar 41 is arranged corresponding to the flow blocking structure 50. The other water inlet groove 30 is not provided with a flow blocking structure 50, and the vortex eliminating part 40 corresponding to the water inlet groove 30 is provided with a plurality of pillars 41, and the plurality of pillars 41 are arranged on both sides of the water inlet 31. Of course, both water inlet grooves 30 can also be provided with a flow blocking structure 50 or neither of them can be provided with a flow blocking structure 50.

[0048] In this embodiment, the cover plate 42 is spaced apart from the side wall 10 , the length of the cover plate 42 is adapted to the width of the water inlet 31 , and the width of the cover plate 42 is 1 / 3 to 1 / 2 of the length of the cover plate 42 .

[0049] Specifically, the cover plate 42 is spaced apart from the side wall 10, and water can flow into the water inlet trough 30 along the gap between the cover plate 42 and the side wall 10. The length of the cover plate 42 is adapted to the opening width of the water inlet 31, and the width of the cover plate 42 is adapted to the range of the vortex formed by the water inlet 31 to eliminate the vortex at the water inlet 31.

[0050] like Figure 1 As shown, the vortex-eliminating ship lock further includes a gate 60 , a mounting structure 11 is provided on the side wall 10 , the gate 60 is connected to the mounting structure 11 , and the water inlet 31 and the water outlet 32 ​​are respectively provided on both sides of the gate 60 .

[0051] Specifically, the gate 60 is slidably connected to the mounting structure 11. After the ship enters the lock chamber, the water pump in the side wall 10 is turned on, and the water flows in from the water inlet 31 of the water inlet trough 30 and flows out from the water outlet 32. During this process, the gate 60 is tightly closed. After the drainage is completed, the gate 60 is opened and the ship sails out of the lock chamber. The water inlet 31 is opened at the bottom of the side wall on one side of the gate 60 to facilitate drainage, and the water outlet 32 ​​is opened on the bottom layer 20 on the other side of the gate 60 to achieve water flow moving on both sides of the gate 60. Optionally, a water level monitoring device is also provided at the water outlet 32 ​​to detect the drainage situation. A maintenance room 70 is also provided on the side wall 10 to facilitate the maintenance of the water pump.

[0052] In this embodiment, the vortex elimination hole 421 is rectangular, there are multiple vortex elimination holes 421, and the multiple vortex elimination holes 421 are arranged on the cover plate 42 at intervals. The height of the support 41 is adapted to the height of the water inlet 31.

[0053] Specifically, multiple vortex-eliminating holes 421 are evenly distributed on the cover plate 42, and the height of the pillar 41 is consistent with the height of the water inlet 31, so that when the bottom elevation of the cover plate 42 is flush with the top elevation of the water inlet trough 30, the vertical height of the structure can be greatly reduced to prevent the cover plate 42 from being scratched when the ship passes through the lock. The arrangement of multiple vortex-eliminating holes 421 allows the water flow entering the water inlet trough 30 to enter the water inlet trough 30 along multiple smaller holes rather than one hole. The principle is that water flows into the water inlet trough 30 from multiple directions, and water flows in different directions collide with each other, which can offset the energy they carry, thereby avoiding the formation of large vortices.

[0054] In this embodiment, the area of ​​the vortex elimination hole 421 is 30% to 50% of the area of ​​the cover plate 42 .

[0055] Specifically, if the area of ​​the multiple vortex-eliminating holes 421 is too small, it will be difficult for the cover plate 42 to achieve the vortex-eliminating effect. If the overall area of ​​the vortex-eliminating holes 421 is too large, it means that the number of vortex-eliminating holes 421 opened on the cover plate 42 is too large. Too many vortex-eliminating holes 421 will cause the overall structural strength of the cover plate 42 to decrease. When the drainage time is long or the drainage is repeated multiple times, the cover plate 42 may break, resulting in the inability of the vortex-eliminating component to eliminate the vortex, affecting the navigation safety.

[0056] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: by setting the vortex elimination ship lock including the lock chamber and the vortex elimination member 40, the lock chamber includes the side wall 10 and the bottom layer 20, the lock chamber is provided with a water inlet trough 30, the side wall 10 is provided with a water inlet 31 of the water inlet trough 30, the bottom layer 20 is provided with a water outlet 32 ​​of the water inlet trough 30, the vortex elimination member 40 includes a pillar 41 and a cover plate 42, the pillar 41 is arranged on the bottom layer 20, the pillar 41 is spaced apart from the side wall 10 and is arranged corresponding to the water inlet 31, the cover plate 42 is arranged on the top of the pillar 41, the cover plate 42 is provided with a vortex elimination hole 421, the cover plate 42 and the water inlet 31 Accordingly, a vortex-eliminating member 40 is provided, wherein the pillar 41 of the vortex-eliminating member 40 is provided on the bottom layer 20 of the lock chamber, and the cover plate 42 is provided on the top of the pillar 41; in the drainage stage, the water in the lock chamber enters the water inlet 31 along the four sides of the cover plate 42, the vortex-eliminating holes 421 on the top of the cover plate 42, and the gap between the pillar 41 and the side wall 10. The water in the lock chamber is diverted at the water inlet 31 and enters the water inlet trough 30 along multiple paths, thereby improving the efficiency of water delivery and avoiding the formation of a vortex at the water inlet 31 that affects the durability of the ship lock. At the same time, the cover plate 42 has a small height in the vertical direction, and even if a ship passes by, it will not scratch the bottom of the ship, thereby providing higher safety.
