Description

Technical Field

[0001] The present application relates to the field of ship navigation technology, and in particular to a ship navigation system and a ship navigation method. Background Art

[0002] The ship navigation system can obtain real-time information on the ship's location, speed, heading, etc. through various sensors and monitoring equipment. This enables the maritime management department to promptly detect potential dangerous situations, such as ships deviating from their routes or being too close to other ships, and notify the captain in advance to take avoidance measures, greatly reducing the risk of collision and ensuring the continuity of water transportation.

[0003] For regions that rely on inland waterway transportation for cargo transportation, this system ensures that bulk commodities such as coal, ore, and grain can be efficiently circulated between different waters, thereby achieving docking with domestic and foreign markets. Compared with other modes of transportation, water transportation has the advantages of large volume and low cost. The dam navigation system enables large cargo ships to continue to use water transportation, reducing the links and costs of cargo transshipment. With the help of the dam navigation system, transportation costs can be greatly reduced and the competitiveness of enterprises can be improved;

[0004] Nowadays, in order to save time for ships to pass through the dam, most dams often use ship lifts to transport ships, so that ships can pass through the dam quickly and easily and enter the next water area for further transportation. However, since the river water contains a large amount of sediment when it flows, the sediment will accumulate at the bottom of the riverbed as the river water flows. Because of the water storage construction of the dam, the sediment at the bottom of the river will accumulate at the root of the dam body. At the same time, the bottom of the ship lift also contains a large amount of sediment. If the sediment is allowed to accumulate, it will affect the normal operation of the ship transporter.

[0062] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] The embodiment of the present application provides a ship navigation system. When a ship passes through a dam, the ship can be lifted by a ship lift of the ship navigation system, so that the ship can quickly pass through the dam and enter the next water area for transportation.

[0064] like Figure 1As shown, the ship navigation system includes a ship lift 1 and a main channel 2, wherein the ship lift 1 is arranged in the main channel 2, and the ship lift 1 is provided with an inlet 15 and an outlet. The ship can enter the ship lift 1 through the inlet 15 of the ship lift 1 through the main channel 2, and rise under the drive of the ship lift 1, and then enter the next water area through the outlet.

[0065] The main channel 2 is also provided with a desilting area 21, which is located at the inlet 15 of the ship lift 1. The river water contains a large amount of silt when it flows, and the silt will accumulate at the bottom of the riverbed as the river water flows. Because of the water storage construction of the dam, the silt at the bottom of the river will accumulate at the root of the dam body. The desilting area 21 is prone to silt accumulation. If not handled in time, it is easy to cause more silt accumulation, affecting the operation of ships.

[0066] The ship navigation system provided in this embodiment further includes a dredging mechanism 3, which is used to clean the sludge in the dredging area 21 to ensure smooth navigation of the ship. Figure 1 and Figure 2 As shown, the silt removal mechanism 3 includes a flushing part 31 and an air filling part 32, wherein Figure 3 As shown, the flushing part 31 includes a first flushing pipe 311 and a second flushing pipe 312. The flushing port of the first flushing pipe 311 is arranged toward the bottom of the silting area 21. The high-pressure water flow flushed out by the flushing port of the first flushing pipe 311 will act on the sediments such as silt accumulated in the silting area 21 and disperse these sediments. The height of the flushing port of the second flushing pipe 312 is higher than that of the flushing port of the first flushing pipe 311, and can be used as a water flow in the silting area 21 to provide rotational power. At the same time, the inflation part 32 The inflation port of the inflation pipe 321 is also arranged toward the dredging area 21, and high-pressure gas is flushed into the dredging area 21. The high-pressure gas is mixed with the water flow, and combined with the rotational power provided by the second flushing pipe 312, the water flow in the dredging area 21 forms a vortex, and the sediment is stirred upward by the vortex, and the upward power of the bubbles is combined to enhance the stirring effect of the sediment, prolong the stirring time of the sediment, and facilitate the discharge of the sediment outside the main channel 2, thereby reducing the amount of sediment in the dredging area 21 and avoiding the sediment from affecting the passage of ships.

[0067] That is to say, in this embodiment, through the arrangement of the flushing part 31 and the inflation part 32, an effective vortex can be formed in the dredging area 21, and the sludge in the dredging area 21 can be cleaned, thereby avoiding the formation of a large amount of sludge accumulation at the entrance 15 of the ship lift 1, thereby avoiding the impact of sludge accumulation on the passage of ships and ensuring the normal use of the ship lift 1.

[0068] like Figure 3 , Figure 4 and Figure 5As shown, the water outlet end of the second flushing water pipe 312 is provided with a seat body 313, an adjusting member 314 and a nozzle 317, wherein the seat body 313 is fixed to the end of the second flushing water pipe 312, and the seat body 313 is provided with a plurality of water spray outlets, each of which is connected to the second flushing water pipe 312, and each of which is connected to a nozzle 317 via an adjusting member 314, that is, the plurality of nozzles 317 at the water outlet end of the second flushing water pipe 312 can form a spray net, and the adjusting member 314 is used to adjust the rotation angle of the nozzle 317 relative to the seat body 313.

[0069] The second flushing pipe 312 is provided with a plurality of nozzles 317 , and each nozzle 317 can adjust its water spraying angle through the adjusting member 314 to ensure that the water flow flushed out through the second flushing pipe 312 can provide rotational power to the water flow in the dredging area 21 , thereby ensuring that a vortex is formed in the dredging area 21 .

[0070] Of course, in the present embodiment, a plurality of second flushing water pipes 312 may also be provided, each of which is provided with a nozzle 317. By arranging the angles of the nozzles 317 of each second flushing water pipe 312, the rotational power provided by the water flow flushed out by each second flushing water pipe 312 can form a vortex in the dredging area 21. By arranging a plurality of nozzles 317 with adjustable angles at the end of the second flushing water pipe 312, the overall structure can be simplified while realizing the formation of a vortex in the dredging area 21.

[0071] Specifically, there is no limit on the number of nozzles 317, which can be set according to actual conditions, and there is no limit on the angle of each nozzle 317 relative to the seat body 313, which can be adjusted according to actual conditions combined with calculations, experiments, etc. to ensure that a vortex can be formed in the dredging area 21.

[0072] like Figure 5 As shown, the regulating member 314 includes a rotary valve 315, which is used to control the water outlet direction of the nozzle 317. The rotary valve 315 and the nozzle 317 are also connected by a ball joint. The nozzle 317 can rotate in any direction relative to the rotary valve 315. The structure is simple and the adjustment is convenient. Figure 5 As shown, the rotary valve 315 is provided with a connecting cavity, the inner wall surface of which is a spherical structure, and the nozzle 317 is provided with a spherical joint 316, which is located in the connecting cavity and can rotate arbitrarily in the connecting cavity.

[0073] Of course, in this embodiment, the nozzle 317 can also rotate around the axis relative to the seat body 313, and the connection of the ball joint can realize the rotation of the nozzle 317 relative to the seat body 313 in any direction, which has better flexibility.

[0074] The structure of the water outlet end of the first flushing water pipe 311 is not limited, and may be consistent with or inconsistent with the structure of the water outlet end of the second flushing water pipe 312 .

[0075] The height of the punch of the second flush pipe 312 is higher than the height of the punch of the first flush pipe 311, and the height difference may be 35 mm-80 mm, so that there is a certain adjustable space between the two flush pipes.

[0076] The flushing part 31 also includes a high-pressure water pump 318. The first flushing pipe 311 and the second flushing pipe 312 are respectively connected to the high-pressure water pump 318, and the high-pressure water flow is provided by the high-pressure water pump 318. The first flushing pipe 311 and the high-pressure water pump 318 can also be set to be detachably connected, such as by using a snap connection, a bolt connection, etc., so that it is convenient to repair or replace the first flushing pipe 311 in case of corrosion or damage after long-term use. The second flushing pipe 312 and the high-pressure water pump 318 can also be detachably connected.

[0077] The inflation part 32 includes two inflation tubes 321, namely a first inflation tube 3211 and a second inflation tube 3212, wherein the height of the inflation port of the first inflation tube 3211 is lower than the height of the inflation port of the second inflation tube 3212, so as to inflate air to different positions of the dredging area 21, and to achieve a better effect of stirring the sludge by bubbles, and to provide sufficient space for position adjustment of the two inflation tubes 321. The height difference of the inflation ports of the two inflation tubes 321 can be determined by calculation, experiment, etc. according to actual conditions, such as the height difference can be within the range of 35mm-80mm, which is not specifically limited here.

[0078] Of course, in the present embodiment, only one air pipe 321 may be used. Compared with inflating the dredging area 21 through one air pipe 321, jetting air into the dredging area 21 through two air pipes 321 can inflate different positions of the dredging area 21, and the effect of stirring the sludge through bubbles is better; and compared with the solution of inflating through three or more air pipes 321, it can simplify the overall structure and reduce costs.

[0079] The inflation part 32 also includes an air compressor 322, which is connected to the inflation tube 321 and is used to compress air to form high-pressure gas and provide high-pressure gas to the inflation tube 321. The air compressor 322 and the inflation tube 321 can be detachably connected, such as by a snap connection, a threaded connection, etc., so that the inflation tube 321 can be repaired or replaced in case of corrosion or damage after long-term use.

[0080] like Figure 1 and Figure 2As shown, the ship navigation system also includes a secondary channel 4, and there are two secondary channels 4. The two secondary channels 4 are respectively located on both sides of the main channel 2, and the secondary channels 4 are connected to the silt removal area 21. The flushing part 31 is fixed to one secondary channel 4 through the first fixing member 5, and the inflation part 32 is fixed to the other secondary channel 4 through the second fixing member 6. The setting of the secondary channel 4 is convenient for fixing the flushing part 31 and the inflation part 32. Of course, in this embodiment, there is no restriction on the specific fixing position and method of the flushing part 31 and the inflation part 32. The setting of the secondary channel 4 can facilitate the fixing of the flushing part 31 and the inflation part 32, and can also prevent the flushing part 31 and the inflation part 32 from affecting the ship navigation of the main channel 2.

[0081] like Figure 3 As shown, the first fixing member 5 includes a first fixing block 51, a first clamp 52 and a first sleeve 53. The first fixing block 51 is fixed to the inner wall (such as the bottom wall) of the secondary channel 4. The first clamp 52 is fixed to the first fixing block 51, such as by bolts or through-clamping. The first sleeve 53 is clamped between the first clamp 52 and the first fixing block 51. The first sleeve 53 is sleeved outside the first flush water pipe 311 and the second flush water pipe 312. The first sleeve 53 can provide protection for the first flush water pipe 311 and the second flush water pipe 312. The first fixing block 51 has a certain height, which can leave a certain gap between the first sleeve 53, the first flush water pipe 311, the second flush water pipe 312 and the bottom surface of the secondary channel 4 to avoid wear caused by direct contact and extend the service life.

[0082] like Figure 6 and Figure 7 As shown, the second fixing member 6 includes a second fixing block 61, a second clamp 62 and a second sleeve 63. The second fixing block 61 is fixed to the inner wall (such as the bottom wall) of the secondary channel 4. The second clamp 62 is fixed to the second fixing block 61, such as by bolts 64 or through-clamping. The second sleeve 63 is clamped between the second clamp 62 and the second fixing block 61. The second sleeve 63 is sleeved outside the inflation tube 321. The second sleeve 63 can provide protection for the inflation tube 321. The second fixing block 61 has a certain height, which can leave a certain gap between the second sleeve 63, the inflation tube 321 and the bottom surface of the secondary channel 4 to avoid wear caused by direct contact and extend the service life.

[0083] The height of the first fixed block 51 is higher than that of the second fixed block 61. This arrangement makes it easier for the height of the flushing port of the first flushing pipe 311 to be higher than that of the inflation port. The inflation port sprays air toward the dredging area 21 from a relatively low position, thereby extending the time that bubbles stay in the water and giving full play to the stirring effect of the bubbles. The nozzle 317 is set at a relatively high position, and the flushing port of the first flushing pipe 311 can spray water downward at an angle to disperse the sludge in the dredging area 21.

[0084] like Figure 8-Figure 13 As shown, the ship lift 1 includes a ship lift frame 11, a lifting plate 12 and a plurality of tension components 13, wherein the ship lift frame 11 is arranged in the main channel 2, an inlet 15 is arranged at the bottom of the ship lift frame 11, an outlet is arranged at the top, a gate 16 may be arranged at the outlet, a lifting chamber 111 is arranged in the ship lift frame 11, and the lifting chamber 111 is communicated with the inlet 15 and the outlet, the lifting plate 12 is arranged in the lifting chamber 111, and can move upward or downward relative to the lifting chamber 111, and the tension component 13 is used to drive the lifting plate 12 to rise and fall.

[0085] The vessel moves along the main channel 2 and can enter the lifting chamber 111 from the entrance 15 to the top of the lifting plate 12. Each pulling assembly 13 can pull the lifting plate 12 so that the lifting plate 12 moves upward in the lifting chamber 111 and drives the vessel to move upward to the exit. Then the gate 16 opens and the vessel can enter the next water area from the exit.

[0086] The boat lift body 11 is provided with a plurality of tension grooves 112 on the two side walls of the lifting chamber 111, and each tension assembly 13 is arranged in each tension groove 112 in a one-to-one correspondence. The tension assembly 13 includes a chain rope 131 and a buoyancy part 132 (such as a floating barrel), the buoyancy part 132 is located in the tension groove 112, the chain rope 131 is connected to the buoyancy part 132, and one end of the chain rope 131 is connected to the lifting plate 12.

[0087] like Fig.11 and Fig.13 As shown, the bottom of the boat lift body 11 is also provided with a water inlet buoyancy part 14 connected with each tension groove 112. The water inlet buoyancy part 14 is used to adjust the amount of water in the tension groove 112 (i.e., adjust the liquid level in the tension groove 112). When the amount of water in the tension groove 112 increases and the liquid level rises, the buoyancy part 132 will rise due to the buoyancy effect, and the lifting plate 12 will fall under the action of gravity. When the amount of water in the tension groove 112 decreases and the internal liquid level falls, the buoyancy part 132 will fall with the liquid level under the action of gravity, and drive the lifting plate 12 to rise through the chain 131. In other words, the amount of water in the tension groove 112 is adjusted by the water inlet buoyancy part 14, and the lifting plate 12 is driven to rise and fall by the gravity and buoyancy of the buoyancy part 132, which has a simple structure, low energy consumption and low cost.

[0088] like Fig.13 , Figure 15-17 As shown, the tension assembly 13 also includes a pulley block 133, which is also located in the tension groove 112. The pulley block 133 includes a plurality of pulleys, such as Fig.16 As shown, the multiple pulleys of the pulley group 133 include a movable pulley 1331 and a fixed pulley 1332, wherein the fixed pulley 1332 can be fixed to the inner wall of the tension groove 112, and the floating bucket is connected to the movable pulley 1331 (such as Fig.17As shown in the figure, the chain rope 131 is a cable wound around each pulley 1331 of the pulley block 133. By setting the pulley block 133, the load-bearing effect of the ship lift 1 can be increased, and the cable can be converted into multiple strands. By changing the height of the floating barrel, the height of the linked lifting plate 12 can be controlled, thereby improving the working efficiency of the ship lift 1.

[0089] like Fig.13 As shown, the water inlet buoyancy part 14 includes a main pipe 141, a branch pipe 143 and a plurality of branch pipes 142 arranged in parallel at intervals, wherein the two ends of the branch pipe 142 are respectively connected to the main pipe 141 and the branch pipe 143, the diameter of the branch pipe 143 is smaller than the diameter of the main pipe 141, and the branch pipe 143 is connected to each of the tension grooves 112. The water entering the main pipe 141 can enter the branch pipe 143 along each branch pipe 142, and then be distributed to each tension groove 112 by the branch pipe 143.

[0090] Of course, the main pipe 141 can also be directly connected to each tension groove 112, and the arrangement of the main pipe 141, the branch pipe 142 and the diversion pipe 143 can improve the uniformity of water entering each tension groove 112, so that the liquid level height in each tension groove 112 is uniform, thereby ensuring that the force of each tension component 13 on the lifting plate 12 is uniform, avoiding the lifting plate 12 from tilting, and at the same time, preventing the lifting plate 12 from "running away".

[0091] The ship navigation system also includes a linkage device 7, such as Figure 1 , Figure 8 Fig.13 and Fig.14 As shown, the linkage device 7 is arranged on a side wall of the ship lift 1 facing the main channel 2, and can be specifically arranged on a side wall of the ship lift frame 11.

[0092] like Fig. 9 As shown, the linkage device 7 includes a laser sensor 71, a camera 72, a scanner 73 and a processor (not shown in the figure), wherein the laser sensor 71 is used to obtain the position and distance of the ship in the main channel 2 by emitting and receiving laser signals; the camera 72 is used to take photos of the ship; the processor is used to calculate the speed of the ship according to the distance and time detected by the laser sensor 71, and can also be used to compare the registered ships stored in the system according to the photos and determine the registered information of the ship; the scanner 73 is used to scan the water holding capacity and the height of the highest point of the ship.

[0093] The laser sensor 71 is used to periodically emit a laser signal to one side of the main channel 2. If there is a ship in the main channel 2, the laser signal is reflected to the laser sensor 71, and the laser sensor 71 can obtain the specific position and distance of the ship. Then the laser sensor 71 emits the laser signal again and obtains the new position and distance. The running speed V= (L1-L2) / (T2-T1) of the ship can be calculated based on the two distances L1, L2 and times T1, T2.

[0094] Combined with the distance and the running speed, the arrival time required for the vessel to reach the ship lift 1 can be known. If the arrival time is less than the preset time, the vessel is photographed by the camera 72, and the photograph is compared with the registered vessels stored in the background database, and the registered information of the vessel is retrieved at the same time, which includes but is not limited to the total height of the vessel.

[0095] The scanner 73 is used to scan the height of the highest point of the ship, and then the processor can calculate the waterline depth of the ship based on the total height of the ship and the height of the highest point of the ship, so as to facilitate the adjustment of the position of the lifting plate 12 of the elevator 1 so that after the ship enters the lifting chamber 111 through the entrance 15, it will not interfere with the lifting plate 12.

[0096] The processor may include two processing units, wherein one processing unit is a calculation unit for calculating the running speed of the ship according to the ship distance and time detected by the laser sensor 71, and the other processing unit is a comparison unit for comparing the photos taken by the camera 72 with the registered ships stored in the database. The calculation unit can also be used to calculate the draft depth of the ship according to the total height of the ship and the height of the highest point of the ship scanned by the scanner 73.

[0097] The processor can also be connected to the ship lift 1 by signal. The processor can send control instructions to the water inlet buoyancy part 14 according to information such as the arrival time of the ship and the water holding depth, so that the water inlet buoyancy part 14 adjusts the water volume in the tension groove 112, and then adjusts the position of the buoyancy part 132 in the tension groove 112, and drives the position of the lifting plate 12 to change through the chain rope 131 to adapt to the water holding capacity of different ships, so as to ensure that the ship can pass through the dam smoothly through the ship lift 1.

[0098] The present application also provides a method for ship navigation, which is applicable to the above-mentioned ship navigation system. Fig.18 As shown, the ship navigation method includes the following steps:

[0099] S1: The sediment in the silt removal area 21 is cleaned by the silt removal mechanism 3 .

[0100] Specifically, high-pressure water flow is sprayed toward the silting area 21 through the first flushing pipe 311 and the second flushing pipe 312 of the flushing part 31 respectively, and high-pressure gas is sprayed toward the silting area 21 through the inflation pipe 321 of the inflation part 32. The first flushing pipe 311 specifically sprays high-pressure water flow toward the bottom of the silting area 21, which can disperse the sediments such as silt gathered at the bottom of the silting area 21. Then, driven by the high-pressure water flow flushed out by the second flushing pipe 312 and the high-pressure gas sprayed from the inflation pipe 321, a vortex can be formed in the silting area 21, so that the dispersed sediments are rolled up by the vortex, and combined with the stirring effect of the bubbles formed by the high-pressure gas, the sediments are brought to a high position in the silting area 21 and moved out of the main channel 2, thereby realizing the cleaning of the sediments at the entrance 15 of the ship lift 1.

[0101] S2: Monitor the vessel information and obtain the vessel information.

[0102] The ship information is monitored through the linkage device 7, and the acquired ship information includes the ship's position, distance, speed, arrival time, height of the highest point of the ship, draft depth of the ship and other information, which is convenient for subsequent control of the actions of other components of the ship passage system according to the ship information.

[0103] S3: adjusting the ship lift 1 according to the ship information so that the ship can enter the ship lift 1 from the main channel 2.

[0104] The ship lift 1 can be adjusted according to the ship information, so that the ship can enter the ship lift 1 from the main channel 2, avoiding interference between the ship lift 1 and the bottom of the ship.

[0105] Specifically, the water volume in the tension groove 112 is adjusted by the water inlet buoyancy part 14, and then the position of the buoyancy part 132 in the tension groove 112 is adjusted, and the position of the lifting plate 12 is changed by the chain rope 131 to adapt to the draft of different ships and ensure that the ship can smoothly enter the ship lift 1 from the main channel 2.

[0106] S4: After the ship enters the ship lift 1, the ship lift 1 drives the ship to rise.

[0107] After the vessel enters the ship lift 1 , the ship lift 1 drives the vessel to rise to the top, and then opens the gate 16 located at the top of the ship lift 1 , so that the vessel can enter the next water area through the exit of the ship lift 1 .

[0108] The order of the above steps S1 and S2 is not particular. In step S1, the silt removal mechanism 3 can clean the sediment in the silt removal area 21 at intervals of a preset time, or in step S2, when the arrival time of the ship in the ship information is less than the set time or the distance of the ship is less than the set distance, step S1 is performed, and the sediment in the silt removal area 21 is cleaned by the silt removal mechanism 3.

[0109] The sediment in the desilting area 21 is cleaned by the desilting mechanism 3 to prevent sediments such as mud and sand at the entrance 15 of the ship lift 1 from affecting the passage of ships, thereby ensuring the normal use of the ship lift 1.

[0110] like Fig.19 As shown, before step S1, step S0 is also included: adjusting the flushing port angle of the first flushing pipe 311, the flushing port angle of the second flushing pipe 312, and the inflation port angle of the inflation pipe 321 respectively, so that the flushing port of the first flushing pipe 311 can be directed toward the bottom of the dredging area 21, and the high-pressure water flow flushed out by the second flushing pipe 312 and the high-pressure gas charged by the jet pipe can form a vortex in the dredging area 21.

[0111] The step S0 is used to debug the flushing part 31 and the inflation part 32 of the silt removal mechanism 3. The step S0 can be performed in the initial installation state. Specifically, during the use process, frequent debugging is not required.

[0112] During the debugging process, the flushing port of the first flushing pipe 311 is adjusted first. If the structure of the water outlet end of the first flushing pipe 311 is the same as that of the water outlet end of the second flushing pipe 312, the water outlet direction is changed by rotating the rotary valve of the first flushing pipe 311, and then the azimuth is adjusted through the ball joint 316, so as to facilitate the angle adjustment of multiple flushing ports so that they can impact the sediments at the bottom of the river.

[0113] The flushing ports of the second flushing pipe 312 and the inflation ports of the inflation pipe 321 are adjusted, the water outlet direction is changed by rotating the valve of the second flushing pipe 312, and the azimuth is adjusted by the ball joint 316, so that the angles of the multiple water outlets can be adjusted so that they exert a rotating force on the river water. The inflation ports of the first inflation pipe 3211 and the second inflation pipe 3212 are position-adjusted, so that the first inflation pipe 3211 and the second inflation pipe 3212 cooperate with the second flushing pipe 312 to cause a vortex in the water flow of the dredging area 21. At the same time, the bottom sediments impacted by the first flushing pipe 311 can be rotated to reduce the sedimentation downwards, which is convenient for the sediments to be discharged from the main channel 2.

[0114] Furthermore, in the above step S2, monitoring the vessel information and obtaining the vessel information specifically includes:

[0115] The laser sensor 71 emits laser signals along the main channel 2 at regular intervals, and determines the position and distance of the vessel based on the received reflected signals;

[0116] The speed of the ship is calculated based on the distance and time of the ship detected twice by the laser sensor 71. Specifically, the speed of the ship V = (L1-L2) / (T2-T1) can be calculated based on the two distances L1, L2 and the time T1, T2. The arrival time of the ship is calculated based on the distance and the speed of the ship;

[0117] If the arrival time is less than the preset time, a photo of the vessel is taken by the camera 72, and the photo is compared with the registered vessels in the database to obtain the registered information of the vessel, wherein the registered information of the vessel includes the total height of the vessel;

[0118] Scanning the height of the highest point of the vessel by means of the scanner 73, and calculating the waterline depth of the vessel according to the total height of the vessel and the height of the highest point;

[0119] In step S3, adjusting the ship lift 1 according to the ship information includes: adjusting the ship lift 1 according to the waterline depth, specifically adjusting the height of the lifting platform 12 of the ship lift 1.
