Description

Technical Field

[0001] This invention belongs to the field of navigation technology for high dams, and particularly relates to a device and method for dry transport of vessels for navigation through high dams. Background Technology

[0002] The high mountains and deep valleys possess abundant hydropower potential. Currently, several dams ranging from 200 to 300 meters in height have been built or are planned in these areas, forming a cascade hydropower network. While these dams bring power generation benefits, they also create a "half-cut" barrier to traditional waterways due to the huge water level difference and complex terrain conditions, posing a severe challenge to ship navigation and becoming a key bottleneck restricting the connectivity of the western waterway network.

[0003] Traditional solutions include using vertical ship lifts, combinations of vertical ship lifts and locks, and multi-stage locks. However, vertical ship lifts have high construction and maintenance costs, limited lifting capacity, and relatively poor adaptability to changes in water level upstream and downstream. While multi-stage locks can overcome the difficulties of high-head lock water conveyance systems and cavitation in valve sections, they significantly reduce navigation efficiency.

[0004] Therefore, there is an urgent need for a device and method for dry transport of ships navigating high dams. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for dry transport of vessels navigating high dams, in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] A navigation device for vessels operating through high dams, comprising:

[0008] A magnetic levitation channel is provided, which is arranged along the upstream to downstream direction of the water flow, with the high end of the magnetic levitation channel located upstream of the water flow and the low end of the magnetic levitation channel located downstream of the water flow.

[0009] The upstream inclined ship lift is connected at its outlet to the high end of the magnetic levitation channel;

[0010] The downstream inclined ship lift has its inlet end connected to the lower end of the magnetic levitation channel;

[0011] Both the upstream and downstream inclined ship lifts have the same slope as the corresponding construction site.

[0012] The magnetically levitated ship carrier is connected to the upstream inclined ship lift, the magnetically levitated channel, and the downstream inclined ship lift. The magnetically levitated ship carrier moves along the track formed by the upstream inclined ship lift, the magnetically levitated channel, and the downstream inclined ship lift. The magnetically levitated ship carrier is used to hold ships.

[0013] Optionally, the magnetic levitation ship carriage and the magnetic levitation channel are connected by magnetic levitation transmission.

[0014] Optionally, gates are provided at both ends of the magnetic levitation ship carrier, and the line connecting the two gates is parallel to the direction of water flow.

[0015] Optionally, an anti-collision mooring facility is fixed inside the magnetic levitation ship carrier, and the anti-collision mooring facility is used to secure the ship.

[0016] Optionally, the upstream inclined ship lift has the same structure as the downstream inclined ship lift.

[0017] Optionally, the upstream inclined ship lift includes:

[0018] Several parallel tracks are provided, with supporting bottom ends slidably connected to the tracks. The supports constitute a support structure for supporting the bottom of the magnetically levitated ship carriage.

[0019] Optionally, the spacing between two adjacent tracks is equal.

[0020] Optionally, it also includes a large-scale energy storage device for providing the electrical energy required for the operation of the upstream inclined ship lift, the magnetic levitation channel, and the downstream inclined ship lift.

[0021] Optionally, the large-scale energy storage device is used to output electrical energy during peak electricity consumption periods, and the large-scale energy storage device is used to store electrical energy during off-peak electricity consumption periods;

[0022] The large-scale energy storage device is electrically connected to the dam power plant.

[0024] The vessel located upstream moves to the magnetically levitated ship carrier;

[0025] The upstream inclined ship lift raises the magnetically levitated ship carriage to the high end of the magnetically levitated channel;

[0026] The magnetically levitated ship carrier moves along the magnetically levitated channel to the entrance of the downstream inclined ship lift;

[0027] The downstream inclined ship lift moves the magnetically levitated ship carrier to the water surface;

[0028] The vessel moves out of the magnetic levitation ship carrier and enters the downstream section;

[0029] The magnetically levitated ship returns to its starting point.

[0030] Compared with the prior art, the present invention has the following advantages and technical effects:

[0031] This invention improves traffic efficiency by setting up a magnetic levitation channel along the mountainside, eliminating the need for multiple sluice gates and water level adjustments. By using magnetic levitation technology to replace ship self-propulsion, it saves water energy, significantly reduces the risk of ship collisions, and substantially improves navigation efficiency. The invention utilizes a magnetic levitation ship-carrying chamber designed to accommodate different ship types, and tunnels are excavated to accommodate these chambers.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figures 1 to 3This invention discloses a vessel navigating a high dam, comprising:

[0040] The magnetic levitation channel 3 is set along the upstream to downstream direction of the water flow, with the high end of the magnetic levitation channel 3 located upstream of the water flow and the low end of the magnetic levitation channel 3 located downstream of the water flow.

[0041] The upstream inclined ship lift 1 is connected to the high end of the magnetic levitation channel 3 at its outlet.

[0042] The downstream inclined ship lift 4 is connected at its inlet end to the lower end of the magnetic levitation channel 3;

[0043] Both the upstream inclined ship lift 1 and the downstream inclined ship lift 4 have the same slope as the corresponding construction site.

[0044] The magnetic levitation ship carrier 2 is connected to the upstream inclined ship lift 1, the magnetic levitation channel 3 and the downstream inclined ship lift 4. The magnetic levitation ship carrier 2 moves along the track formed by the upstream inclined ship lift 1, the magnetic levitation channel 3 and the downstream inclined ship lift 4. The magnetic levitation ship carrier 2 is used to hold the ship 5.

[0045] In use, the upstream vessel 5 moves to the magnetic levitation ship carrier 2, and the upstream inclined ship lift 1 raises the magnetic levitation ship carrier 2 to the high end of the magnetic levitation channel 3. The magnetic levitation ship carrier 2 moves along the magnetic levitation channel 3 to the entrance of the downstream inclined ship lift 4. The downstream inclined ship lift 4 moves the magnetic levitation ship carrier 2 to the water surface, the vessel 5 moves out of the magnetic levitation ship carrier 2 and enters the downstream area, and the magnetic levitation ship carrier 2 returns to the starting point. This invention improves traffic efficiency by setting up a magnetic levitation channel 3 along the mountain, eliminating the need for multiple sluice gates and water level conversion. By using magnetic levitation technology to replace ship self-propulsion, it saves water energy, significantly reduces the risk of ship collisions, and significantly improves navigation efficiency. The invention designs magnetic levitation ship-carrying chambers 2 that can adapt to different ship types, and excavates tunnels based on these chambers, laying the magnetic levitation channel 3 at the bottom of the tunnels. It also utilizes the mountain slope to construct an upstream inclined ship lift 1 and a downstream inclined ship lift 4, significantly reducing engineering costs. This device can adapt to large water level fluctuations, consumes no water, significantly improves navigation efficiency and safety, and enables the efficient operation of the inland waterway transport system.

[0046] Inclined ship lifts utilize the slope of the hillside to construct the lift, reducing the amount of excavation required while significantly increasing the lifting capacity and cargo throughput.

[0047] When the bottom of the upstream inclined ship lift 1 meets the minimum navigation water level, the ship 5 can enter and exit the magnetic levitation ship carrier 2; when the bottom of the downstream inclined ship lift 4 meets the minimum navigation water level, the ship 5 can enter and exit the magnetic levitation ship carrier 2.

[0048] The gradient of the maglev channel is determined based on the gradient of the upstream mountain, which reduces the amount of excavation while significantly increasing the lifting capacity of the ship lift and increasing cargo throughput.

[0049] As an optional implementation, the magnetic levitation ship carriage 2 and the magnetic levitation channel 3 are connected by magnetic levitation transmission.

[0050] The maglev channel 3 includes a tunnel and a maglev track 10 laid at the bottom of the tunnel. The maglev track 10 is located at the bottom of the tunnel and provides a maglev carriage 2 for travel by magnetic levitation. Since there is no physical contact point between the carriage and the navigation tunnel, the throughput efficiency can be greatly improved and the collision risk caused by the self-propulsion of ships in traditional navigation tunnels can be reduced.

[0051] As an optional implementation, gates 9 are respectively installed at both ends of the magnetic levitation ship carriage 2, and the line connecting the two gates 9 is parallel to the direction of water flow.

[0052] As an optional implementation, the magnetic levitation ship carrier 2 is equipped with a collision protection mooring facility 8, which is used to secure the ship 5.

[0053] The anti-collision mooring facility 8 has a grid-shaped structure for its anti-collision mooring.

[0054] The magnetic levitation ship carrier 2 is used to moor ships 5. The magnetic levitation ship carrier 2 is equipped with anti-collision mooring facilities 8 to ensure the stability of the ship 5. It can also freely change size according to the ship type, hold the ship tightly, and facilitate the rapid movement of the ship carrier. The upstream and downstream gates 9 can be opened freely to facilitate the entry and exit of ships 5. The operation of the ship carrier does not consume water, which solves the problem of water shortage in some hubs. The specific dimensions of the magnetic levitation ship carrier 2 should be determined by the main ship dimensions of the river.

[0055] As an optional implementation, the upstream inclined ship lift 1 and the downstream inclined ship lift 4 have the same structure.

[0056] As an optional implementation, the upstream inclined ship lift 1 includes:

[0057] Several parallel tracks 6 are connected to the bottom of supports 7, and the supports 7 form a support structure to support the bottom of the magnetic levitation ship carriage 2.

[0058] As an optional implementation, the spacing between two adjacent tracks 6 is equal.

[0059] The upstream inclined ship lift 1 is equipped with a total of 5 tracks 6 to assist the magnetic levitation ship carrier 2 to move smoothly up and down. The magnetic levitation ship carrier 2 is supported by a support 7 below to ensure that the magnetic levitation ship carrier 2 is horizontal.

[0060] As an optional implementation, a large-scale energy storage device 11 is also included, which is used to provide the electrical energy required for the operation of the upstream inclined ship lift 1, the magnetic levitation channel 3, and the downstream inclined ship lift 4.

[0061] As an optional implementation, the large-scale energy storage device 11 is used to output electrical energy during peak electricity consumption periods and to store electrical energy during off-peak electricity consumption periods.

[0062] Large-scale energy storage device 11 is electrically connected to the dam power plant.

[0063] In this specific embodiment, the large-scale energy storage device 11 is used for energy storage. During peak electricity consumption periods, each device of the magnetic levitation trunk transport method can use the electrical energy stored in the energy storage device; during off-peak electricity consumption periods, it uses the electrical energy generated by the dam power plant; it can store the excess electrical energy generated by the dam power plant during off-peak electricity consumption periods, and can also be used for emergency energy of the entire hub.

[0064] A method for dry transport of vessels navigating high dams, using the aforementioned dry transport device for vessels navigating high dams, comprising:

[0065] The ship 5, located upstream, moves to the magnetic levitation ship carrier 2;

[0066] The upstream inclined ship lift 1 lifts the magnetic levitation ship carriage 2 to the high end of the magnetic levitation channel 3;

[0067] The magnetic levitation ship carrier 2 moves along the magnetic levitation channel 3 to the entrance of the downstream inclined ship lift 4;

[0068] Downstream inclined ship lift 4 moves the magnetically levitated ship carrier 2 to the water surface;

[0069] Ship 5 moves out of the magnetic levitation carrier 2 and enters the downstream section;

[0070] The magnetically levitated ship carriage 2 returns to the starting point.

[0071] Application example:

[0072] Taking a proposed second-line ship lock as an example, the highest navigable water level upstream of the hub is 293.00m, the lowest navigable water level is 278.00m, the lowest navigable water level downstream is 211.40m, and the maximum operating head is 81.6m.

[0073] The bottom elevation of the upstream inclined ship lift 1 is 275.00m, which can allow ships 5 to enter and exit the magnetic levitation ship carrier 2 when the minimum navigable water level is 278.00m; the bottom elevation of the downstream inclined ship lift 4 is 209.00m, which can allow ships 5 to enter and exit the magnetic levitation ship carrier 2 when the minimum navigable water level is 211.40m.

[0074] The slope of the upstream inclined ship lift 1 is determined based on the slope of the upstream mountain, and the slope of the downstream inclined ship lift 4 is determined based on the slope of the downstream mountain. This reduces the amount of excavation while significantly increasing the lifting capacity of the ship lift, thereby increasing the cargo throughput.

[0075] In this application example, the upstream inclined ship lift 1 is equipped with a total of 5 tracks 6 to assist the magnetic levitation ship carrier 2 to move smoothly up and down, and the magnetic levitation ship carrier 2 is supported below the magnetic levitation ship carrier 2 to ensure that the magnetic levitation ship carrier 2 is horizontal.

[0076] The magnetic levitation ship carrier 2 is used to moor ships 5. It is equipped with anti-collision mooring facilities 8 to ensure the stability of the ship 5. It can also freely change its size according to the ship type, hold the ship tightly, and facilitate the rapid movement of the ship carrier. The upstream and downstream gates 9 can be opened freely to facilitate the entry and exit of ships 5. The operation of the ship carrier does not consume water, which solves the problem of water shortage in some hubs. The dimensions of the magnetic levitation ship carrier 2 should be determined by the main ship dimensions of the river.

[0077] The maglev channel 3 includes a tunnel and a maglev track 10 set at the bottom of the tunnel. The maglev track 10 is used for the maglev ship carriages 2 to travel. There is no physical contact point between the ship carriages and the navigation tunnel, which can greatly improve the throughput efficiency and reduce the collision risk caused by ships self-propelled in traditional navigation tunnels.

[0078] Large-scale energy storage device 11 is used for energy storage. During peak electricity demand periods, the various devices of the magnetic levitation trunk transport method can use the electrical energy stored in the energy storage device; during off-peak electricity demand periods, the electrical energy generated by the dam power plant is used; it can store the excess electrical energy generated by the dam power plant during off-peak electricity demand periods, and can also be used for emergency energy of the entire hub.
