Description

Technical Field

[0001] This invention relates to a ship lift, specifically a hump-type bidirectional inclined plane ship lift, belonging to the technical field of ship passage through high dam auxiliary facilities. Background Technology

[0002] A hump-type inclined ship lift is a device used by ships to pass through dams with significant water level differences. It has the advantage of utilizing natural terrain to reduce civil engineering costs. Hump-type inclined ship lifts typically have a turntable at the summit to adjust the direction of the ship-carrying compartments, accommodating the transition from uphill to downhill travel. Currently, hump-type inclined ship lifts are not widely used, mainly due to the following issues: First, when the ship-carrying compartments transition from uphill to downhill, a reversal is required at the summit, increasing the time and engineering investment for passing through the dam. Second, the ship-carrying compartments need to travel between upstream and downstream of the dam. Due to the layout of the inclined ship lift, it is impossible to use counterweights to balance the weight of the compartments and ships as in vertical ship lifts. Since the weight of the compartments and ships relies on electric power, the operation of an inclined ship lift consumes a large amount of energy. Third, the smaller the slope of the inclined plane ship lift, the smaller the lifting force required. A more economical slope ratio is typically between 1:10 and 1:12. This means that the further the original slope ratio deviates from this range, the greater the engineering investment, which limits the economic application range of inclined plane ship lifts. Fourth, both inclined plane and vertical ship lifts travel back and forth between upstream and downstream, transporting ships in only one direction at a time. The lift cannot transport downstream ships to upstream while simultaneously transporting upstream ships to downstream, and vice versa, resulting in low operating efficiency.

[0003] To address the issue of reversing the direction of the ship-carrying compartment at the dam crest in inclined ship lifts, Chinese patent document CN106930263A discloses a dry-wet dual-transport inclined ship lift with high and low wheels. This design avoids the problem of traditional inclined ship lifts requiring a turntable at the dam crest for reversing the ship-carrying compartment. However, this solution is unidirectional, allowing only one direction of transport at a time, resulting in low operating efficiency. Furthermore, the upstream and downstream track centerlines must be on the same plane without any horizontal turns, placing high demands on the site layout.

[0004] To improve the operating efficiency of inclined plane ship lifts, Chinese patent document publication number CN104404938A discloses a bidirectional inclined plane ship lift, which arranges two sets of tracks and ship-carrying chambers in parallel to achieve bidirectional transportation. Although this scheme enables bidirectional transportation, the parallel arrangement places high demands on the site and significantly increases the project investment.

[0005] In addition, all the loads of the ship chamber in the existing inclined ship lift are driven by electricity, which consumes a lot of energy. In order to reduce energy consumption, the slope should be as gentle as possible, which leads to an increase in the amount of civil engineering work. Summary of the Invention

[0039] Beneficial effects:

[0040] (1) In the camel-hump type bidirectional inclined ship lift of the present invention, by independently arranging two sets of ship-bearing chambers upstream and downstream, the inclined ship lift can be arranged according to the actual terrain (i.e., the horizontal turning angle of the center line of the upstream and downstream tracks can be designed according to the terrain), reducing the amount of excavation and backfilling earthwork and reducing project investment; and the middle channel can transport two ships at the same time, thereby enabling the upstream and downstream ship-bearing chambers to transport ships at the same time, improving the operating efficiency of the inclined ship lift; the bidirectional inclined ship lift not only realizes the bidirectional operation of the ship lift, but can also be arranged according to the actual terrain, with minimal restrictions on the slope, greatly reducing the project cost.

[0041] (2) In the hump-type bidirectional inclined ship lift of the present invention, a counterweight unit is provided to balance the weight of the upstream ship-bearing box assembly and the water and ship it carries during the lifting process. This unit can balance the lifting force of the ship-bearing box and reduce the energy consumption of the inclined ship lift. Furthermore, since the counterweight unit balances the load, the slope can be set according to the actual terrain without increasing energy consumption, thus greatly saving engineering investment.

[0042] (3) In the hump-type bidirectional inclined plane ship lift of the present invention, a U-shaped water seal is provided at the end of the ship-bearing box structure near the middle channel, and a U-shaped waterstop plate is provided at the docking end of the middle channel and the upstream ship-bearing box assembly for cooperating with the U-shaped water seal; thus, when the upstream ship-bearing box assembly or the downstream ship-bearing box assembly climbs along the ship-bearing box track and docks with the middle channel, the U-shaped water seal on the ship-bearing box structure docks with the U-shaped waterstop plate at the end of the middle channel and compresses to ensure the sealing at the docking point, so as to avoid water leakage between the upstream ship-bearing box assembly or the downstream ship-bearing box assembly and the middle channel during docking. This sealing structure is simple and reliable.

[0043] (4) In the hump-type bidirectional inclined plane ship lift of the present invention, a brake is set to brake the lifting drum, so that the upstream ship carrying box assembly stops at a set position, especially the braking when the upstream ship carrying box assembly is connected to the intermediate channel, to ensure the safety and reliability of ship transport overload.

[0044] (5) In the hump-type bidirectional inclined plane ship lift of the present invention, the counterweight unit can be an inclined plane counterweight unit or a vertical counterweight unit, whichever is selected according to actual needs and terrain.

[0045] (6) In the hump-type bidirectional inclined plane ship lift of the present invention, the water level in the intermediate channel is kept at the navigable level by setting up a water conveyance and discharge unit, thereby ensuring the safety and reliability of ship transportation.

Detailed Implementation

[0054] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0055] Example 1:

[0056] This embodiment provides a hump-type bidirectional inclined ship lift, which is arranged according to the actual terrain to improve the operating efficiency of the inclined ship lift and reduce its energy consumption. This ship lift is mainly suitable for the natural sloping terrain on both sides of a high dam and is suitable for both dry and wet transport.

[0057] like Figure 1 and Figure 2 As shown, the hump-type bidirectional inclined ship lift includes: an upstream inclined ship lift 1, an intermediate channel 2, and a downstream inclined ship lift 3. The upstream inclined ship lift 1 and the downstream inclined ship lift 3 are connected via the intermediate channel 2. The upstream inclined ship lift 1 is used to transport upstream vessels or downstream vessels traveling via the intermediate channel 2, while the downstream inclined ship lift 3 is used to transport downstream vessels or upstream vessels traveling via the intermediate channel 2. Simultaneously, the upstream inclined ship lift 1 transports upstream vessels to the intermediate channel 2, while the downstream inclined ship lift 3 transports downstream vessels to the intermediate channel 2. Upstream vessels enter the downstream inclined ship lift 3 via the intermediate channel 2 and are then transported downstream; simultaneously, downstream vessels enter the upstream inclined ship lift 1 via the intermediate channel 2 and are then transported upstream. The intermediate channel 2 can accommodate two vessels traveling in parallel simultaneously, thus enabling synchronous transport of upstream and downstream vessels and doubling the transport efficiency.

[0058] like Figure 3As shown, the upstream inclined ship lift 1 includes: an upstream ship-carrying box assembly 4, a ship-carrying box track 7, a lifting unit, a brake 13, and a counterweight unit. The counterweight unit balances the weight of the upstream ship-carrying box assembly 4 and the water and ship 6 it carries, achieving a balance in the lifting force of the ship-carrying box and reducing the energy consumption of the inclined ship lift. The ship-carrying box track 7 is connected to the intermediate channel 2. Driven by the lifting unit, the upstream ship-carrying box assembly 4 moves along the ship-carrying box track 7, connecting with the intermediate channel 2, allowing the ship 6 inside the upstream ship-carrying box assembly 4 to enter the intermediate channel 2. The operation of the upstream ship-carrying box assembly 4 is driven by the drive unit in the lifting unit to overcome unbalanced loads such as wind load and friction during operation.

[0059] Specifically: such as Figure 4 As shown, the upstream ship-carrying box assembly 4 includes: a ship-carrying box structure 22, a ship-carrying box frame 21, a ship-carrying box working door, and a U-shaped water seal 20. The ship-carrying box structure 22 is arranged on the ship-carrying box frame 21 and supported on the ship-carrying box track 7 by the ship-carrying box frame 21. The ship-carrying box frame 21 can travel along the ship-carrying box track 7 under the action of the lifting unit. The U-shaped water seal 20 is arranged at the end of the ship-carrying box structure 22 near the intermediate channel 2 for sealing connection with the upstream end of the intermediate channel 2. The ship-carrying box structure 22 extends laterally from the ship-carrying box frame 21 on both sides (i.e., it has lateral extensions on both sides) for connecting the lifting unit and the counterweight unit.

[0060] A cleaning device 8 is provided at the end of the ship-carrying box structure 22 away from the intermediate channel 2. When the upstream ship-carrying box assembly 4 returns after completing the transportation task of the ship 6, it can remove the silt from the ship-carrying box track 7 and its surroundings through the cleaning device 8.

[0061] The lifting unit is used to lift the upstream ship-carrying box assembly 4, enabling it to move along the ship-carrying box track 7. As an example, two sets of lifting units are set up, one on each side of the transverse direction at the connection end between the intermediate channel 2 and the upstream inclined ship lift 1.

[0062] The lifting unit includes a power unit, a lifting drum 14, and a lifting wire rope 11. The power unit drives the lifting drum 14 to rotate around its own axis. One end of the lifting wire rope 11 is wound around the lifting drum 14, and the other end is connected to the lateral extension on the corresponding side of the ship-carrying box structure 22. As an example, the power unit includes a motor 16 and a reducer 15. The motor 16 drives the lifting drum 14 through the reducer 15. The rotation of the lifting drum 14 releases or retracts the lifting wire rope 11, thereby driving the upstream ship-carrying box assembly 4 to move along the ship-carrying box track 7.

[0063] In order to brake the lifting drum 14 and keep the upstream ship carrier assembly 4 in a set position (especially when the upstream ship carrier assembly 4 is connected to the intermediate channel 2), a brake 13 is provided on the lifting drum 14.

[0064] In addition, such as Figure 3 As shown, the ship-carrying chamber working door in the upstream ship-carrying chamber assembly 4 includes: an upstream ship-carrying chamber working door 9 located upstream of the ship-carrying chamber structure 22 (i.e., at the end away from the intermediate channel 2) and a ship-carrying chamber intermediate channel working door 10 located at the end of the ship-carrying chamber structure 22 near the intermediate channel 2; by closing the upstream ship-carrying chamber working door 9 and the ship-carrying chamber intermediate channel working door 10, a closed space for transporting the ship 6 is formed inside the ship-carrying chamber structure 22.

[0065] The downstream inclined ship lift 3 has the same structure and composition as the upstream inclined ship lift 1, and the ship-bearing chamber assembly in the downstream inclined ship lift 3 is called the downstream ship-bearing chamber assembly 23.

[0066] The upstream inclined ship lift 1 and the downstream inclined ship lift 3 are arranged independently (i.e., two sets of ship-carrying chambers are arranged independently upstream and downstream). Therefore, the upstream inclined ship lift 1 and the downstream inclined ship lift 3 can be arranged according to the actual terrain. That is, the slope of the upstream inclined ship lift 1 and the horizontal turning angle of the longitudinal centerline of the downstream inclined ship lift 3 can be designed according to the actual terrain.

[0067] The middle channel 2 connects the upstream inclined ship lift 1 and the downstream inclined ship lift 3 at both ends in the longitudinal direction. By connecting the upstream inclined ship lift 1 and the downstream inclined ship lift 3 through the middle channel 2, it is possible to transport ships 6 simultaneously in the upstream and downstream ship-carrying chambers, thereby improving the operating efficiency of the inclined ship lift.

[0068] The intermediate channel 2 is equipped with intermediate channel working gates at both ends of the longitudinal direction, namely the upstream working gate 121 and the downstream working gate 122. The upstream working gate 121 and the downstream working gate 122 are normally closed gates, and are only opened after the ship-bearing chamber structure 22 of the upstream inclined ship lift 1 or the downstream inclined ship lift 3 is sealed and connected with the intermediate channel 2.

[0069] A U-shaped waterstop 19 is pre-embedded in the concrete structure adjacent to the working gate of the intermediate channel (that is, waterstops are pre-embedded in the concrete structure on both sides and bottom of the upstream working gate 121 and the downstream working gate 122 of the intermediate channel at both ends of the intermediate channel 2, forming a U-shaped waterstop 19); when the upstream ship-carrying box assembly 4 or the downstream ship-carrying box assembly 23 climbs along the ship-carrying box track 7 and docks with the intermediate channel 2, the U-shaped water seal 20 on the ship-carrying box structure 22 docks with the U-shaped waterstop 19 at the end of the intermediate channel 2 and compresses to ensure the seal at the docking point, so as to avoid water leakage between the upstream ship-carrying box assembly 4 or the downstream ship-carrying box assembly 23 and the intermediate channel 2 during docking.

[0070] The width at both ends of the intermediate channel 2 is consistent with the inner net width of the corresponding side-bearing structure 22 (to minimize the size of the sealing connection and ensure the reliability of the seal; at the same time, space is reserved for the arrangement of the lifting unit and the counterweight unit, that is, in this scheme, the lifting unit and the counterweight unit are set on the transverse sides at the ends of the intermediate channel 2); the width and length of the middle section are sufficient for two vessels of the largest size currently on the river to navigate in parallel. The water level in the intermediate channel 2 is kept consistent with the water depth of the upstream and downstream bearing assemblies (that is, the water depth in the bearing structure 22 of the upstream bearing assembly 4 and the downstream bearing assembly 23).

[0071] As an example, a limit plate is also provided at the docking end of the ship-carrying carriage track 7 and the intermediate channel 2 to restrict the movement of the ship-carrying carriage frame 21, while keeping the U-shaped water seal 20 in the optimal compression state, ensuring that there is no water leakage when the upstream inclined ship lift 1 docks with the intermediate channel 2, and that the U-shaped water seal 20 is not damaged due to excessive compression force.

[0072] Example 2:

[0073] Based on implementation 1 above, this embodiment provides a specific implementation of the counterweight unit; the counterweight unit in this embodiment is a slope counterweight unit.

[0074] Taking the counterweight unit installed on the upstream inclined ship lift 1 as an example, such as Figure 3 As shown, there are two counterweight units, which are respectively set on the lateral sides of the upstream ship-carrying box assembly 4 (that is, two counterweight units are set in the upstream inclined ship lift 1, two counterweight units are set in the downstream inclined ship lift 3, and the two counterweight units in the downstream inclined ship lift 3 are respectively set on the lateral sides of the downstream ship-carrying box assembly 23).

[0075] The counterweight unit is located outside the corresponding end lifting unit; it includes: counterweight 5, counterweight roller 30, counterweight fixed pulley 29, counterweight track 28, and counterweight wire rope 24. The counterweight fixed pulley 29 is located outside the lifting drum 14 in the lifting unit; one end of the counterweight wire rope 24 is connected to the counterweight 5, and the other end passes through the counterweight fixed pulley 29 and is connected in the opposite direction to the end of the ship-bearing structure 22 near the middle channel 2, that is, outside the connection of the lifting wire rope 11 on the lateral extension of the ship-bearing structure 22.

[0076] The counterweight tracks 28 in the two counterweight units are symmetrically arranged on the slopes on both sides of the ship-carrying carriage track 7. The plane of arrangement of the counterweight tracks 28 is parallel and lower than the plane of arrangement of the ship-carrying carriage track 7. The counterweight 5 is supported on the counterweight tracks 28 by counterweight rollers 30 and can move along the counterweight tracks 28. The counterweight 5 is arranged parallel to the upper surface of the slope below the ship-carrying carriage structure 22, and does not collide with it when it moves under the sides of the ship-carrying carriage structure 22.

[0077] Example 3:

[0078] Based on embodiment 1 above, this embodiment further provides another specific implementation of the counterweight unit; the counterweight unit in this embodiment is a vertical counterweight unit, and the structure of the bidirectional inclined plane ship lift with the vertical counterweight unit is as follows. Figures 5-7 As shown.

[0079] Taking the counterweight unit set on the upstream inclined ship lift 1 as an example, in this embodiment, there are two counterweight units, which are respectively set on the lateral sides of the docking end between the intermediate channel 2 and the upstream ship carrying chamber assembly 4 (that is, two counterweight units are set in the upstream inclined ship lift 1 and two counterweight units are set in the downstream inclined ship lift 3; the two counterweight units of the downstream inclined ship lift 3 are respectively set on the lateral sides of the docking end between the intermediate channel 2 and the downstream ship carrying chamber assembly 23).

[0080] The counterweight unit in this embodiment includes a counterweight 5 and a counterweight wire rope 24. Counterweight shafts 31 are provided on both sides below the docking end of the intermediate channel 2 and the upstream ship carrier assembly 4. The counterweight 5 is arranged in the counterweight shaft. One end of the counterweight wire rope 24 is connected to the counterweight 5, and the other end is wound on the corresponding side of the lifting drum 14. The winding direction of the counterweight wire rope 24 on the lifting drum 14 is opposite to the winding direction of the lifting wire rope 11 on the lifting drum 14. Thus, when the lifting drum 14 retracts the lifting wire rope 11 to lift the upstream ship carrier assembly 4, the counterweight 5 is released downward through the counterweight wire rope 24.

[0081] Example 4:

[0082] Based on the above embodiments 1-3, a water conveyance and discharge unit is further included.

[0083] A water conveying and discharge unit is located near the upstream inclined ship lift 1 on the side of the intermediate channel 2. This unit includes a lift pump 17, an electric valve 18, a lower water conveying pipe 25, an upper water conveying pipe 26, and a discharge pipe 27. The lift pump 17 is connected at both ends to the lower water conveying pipe 25 and the upper water conveying pipe 26, respectively. The other end of the lower water conveying pipe 25 is positioned below the lowest navigable water level upstream, and the other end of the upper water conveying pipe 26 is positioned at the navigable water level of the intermediate channel 2. The discharge pipe 27 is connected at both ends to the lower water conveying pipe 25 and the upper water conveying pipe 26, respectively. An electric valve 18 is located in the middle of the discharge pipe 27 and is normally open. When the water level in the intermediate channel 2 exceeds the navigable water level due to rainfall or other reasons, water from the intermediate channel 2 is discharged upstream sequentially through the upper water conveying pipe 26, the discharge pipe 27, and the lower water conveying pipe 25 until the water level in the intermediate channel 2 drops to the navigable water level (the lift pump 17 is not activated during this process). When the water level in the intermediate channel 2 is detected to be lower than the navigable water level, the electric valve 18 is closed and the booster pump 17 is started to input the upstream water into the intermediate channel 2 through the lower water pipe 25 and the upper water pipe 26 until the water level in the intermediate channel 2 rises to the navigable water level.

[0084] The aforementioned navigable water level is the water level within the ship-bearing structure 22 of the upstream ship-bearing assembly 4.

[0085] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
