Description

Technical Field

[0001] The present invention relates to the technical field of ship lifts, and in particular to a double-channel ship lift arranged along a waterway for reversing ships into a box, and a navigation method. Background Art

[0002] Existing ship lifts generally only have one pilot channel each upstream and downstream, and when the ship carriage docks with the upstream and downstream, only one side is connected to the pilot channel. Since the pilot channel usually only allows ships to sail in one direction, piers, pontoons, etc. are usually set up in the open part of the pilot channel at a certain distance from the ship carriage as waiting points for ships. After the ship leaves the ship carriage, it must first pass through the waiting point to make way for the waterway. Only ships heading in the opposite direction can enter the ship carriage from the waiting point. During this period, the ship carriage is generally in a docking state waiting for the ship to enter. When a large number of ships need to queue up to pass through the lock, this waiting time between the two carriages significantly reduces the navigation efficiency of the ship lift. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a double-channel ship lift and navigation method arranged along the waterway, which can greatly reduce the time for ships to wait for ships heading in the opposite direction to enter the cabin after leaving the cabin, thereby significantly improving the navigation efficiency of the ship lift.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a double-pilot channel for reversing ships into a box-type ship lift arranged along the waterway, including a ship lift located on the downstream side of the dam, an upstream straight pilot channel and an upstream reversing ship pilot channel are respectively provided between the upper part of the ship lift and the upstream water area of the dam, and a downstream straight pilot channel and a downstream reversing ship pilot channel are respectively provided between the lower part of the ship lift and the downstream water area of the dam.

[0005] Preferably, the ship lift is a fully balanced vertical ship lift, and its civil engineering structure includes four towers, between which a ship compartment and a driving mechanism for driving the ship compartment to move up and down are provided, and on both sides of the ship compartment are provided ship compartment doors that can be opened during docking.

[0006] Preferably, the ship lift is provided with four lock heads, including an upstream upper lock head located on the upstream side of the upstream elevation, an upstream lower lock head located on the downstream side of the upstream elevation, a downstream upper lock head located on the upstream side of the downstream elevation, and a downstream lower lock head located on the downstream side of the downstream elevation.

[0007] Preferably, the upstream straight pilot channel is connected to the upstream upper gate; the downstream straight pilot channel is connected to the downstream lower gate.

[0008] Preferably, after the upstream ship-turning pilot channel bypasses the tower column, it turns around and connects with the upstream lower lock head; the area where the direction is turned is the upstream ship-turning area.

[0009] Preferably, the upstream straight pilot channel and the upstream reverse ship pilot channel are overhead arranged by a plurality of supporting structures, and the parts of the supporting structures spanning the downstream straight pilot channel and the downstream reverse ship pilot channel are provided with gaps for ships to pass through.

[0010] Preferably, the upstream straight pilot channel and the upstream reverse ship pilot channel share a middle retaining wall.

[0011] Preferably, after the downstream ship-turning pilot channel bypasses the tower column, it turns around and connects with the downstream upper lock head; the area where the direction is turned is the downstream ship-turning area.

[0012] The present invention also discloses a navigation method for transferring a ship into a box-type ship lift using the double-guideway arranged along the waterway, which comprises the following steps:

[0013] When a large number of ships need to queue up to pass through the ship lift, navigation is carried out by synchronous docking of both sides of the ship support compartment. Specifically:

[0014] S1: Downstream ships enter the upstream ship-turning pilot channel in advance and queue up in order. The ship at the front of the queue adjusts its stern at the upstream ship-turning area and waits for the ship to turn into the carriage; upstream ships enter the downstream ship-turning pilot channel in advance and queue up in order. The ship at the front of the queue waits at the downstream ship-turning area;

[0015] S2: When the ship carriage reaches the upstream docking elevation, its upstream side docks with the upstream upper lock head, and its downstream side docks with the upstream lower lock head. Then the upstream ship in the ship carriage sails out of the ship carriage and sails to the upstream waters through the upstream straight pilot channel. At the same time, the ship waiting in the upstream reverse ship area can reverse into the ship carriage. After the ship enters and exits the ship carriage, the ship carriage is undocking with both ends at the same time, and the ship carriage can move downward;

[0016] S3: When the ship-carrying compartment descends to the downstream docking elevation, its upstream side docks with the downstream upper lock head, and its downstream side docks with the downstream lower lock head. Then the downstream ship in the ship-carrying compartment sails out of the ship-carrying compartment and sails to the downstream waters through the downstream straight pilot channel. At the same time, the ship waiting in the downstream reverse ship area can reverse into the ship-carrying compartment. After the ship enters and exits the compartment, the ship-carrying compartment is undocking from both ends at the same time, and the compartment can move upward.

[0017] The present invention also discloses a navigation method for the above-mentioned double-pilot channel ship-into-box ship lift arranged along the waterway, which includes the following steps: when the number of ships is small and there is no need to queue, navigation is carried out by adopting a single-sided docking method of the ship receiving box. At this time, the upstream ship-inverting pilot channel and the downstream ship-inverting pilot channel are not put into use, and ships directly enter and exit the ship receiving box through the upstream straight pilot channel and the downstream straight pilot channel.

[0018] Beneficial effects of the present invention:

[0019] 1. The present invention provides dual pilot channels and synchronized docking on both sides of the ship receiving compartment, so that after a ship leaves the compartment, the next ship can enter the compartment immediately, thereby greatly reducing the waiting time between ships leaving and entering the compartment. When a large number of ships need to queue up to pass through the ship lift, compared with a conventional ship lift with only one pilot channel upstream and downstream, the time it takes for a ship to wait for a ship heading in the opposite direction to enter after leaving the compartment can be greatly reduced, thereby significantly improving the navigation efficiency of the ship lift.

[0020] 2. The ship-carrying compartment is arranged along the direction of the waterway, and a reverse ship pilot channel is provided for ships to queue up and reverse the traveling compartment. Compared with the double pilot channel ship lift arranged perpendicular to the waterway, the structure is more compact and the civil engineering workload is smaller.

[0021] 3. When there are fewer ships and no need to queue, the lock can be navigated using the single-sided docking method of the ship-carrying compartment. At this time, the ship does not need to reverse the ship, which is conducive to reducing the time required for a single ship to pass through the lock. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 7As shown, a double-channel ship-turning-entry ship lift arranged along the waterway includes a ship lift 2 located on the downstream side of the dam 1, an upstream straight pilot channel 3 and an upstream ship-turning pilot channel 4 are respectively provided between the upper part of the ship lift 2 and the upstream water area of the dam 1, and a downstream straight pilot channel 6 and a downstream ship-turning pilot channel 7 are respectively provided between the lower part of the ship lift 2 and the downstream water area of the dam 1. Furthermore, in addition to being located behind the dam 1, the ship lift 2 described in this patent can also be located on the downstream side of other water barriers such as mountains according to actual project conditions, and the pilot channel can also be set as a pilot culvert.

[0031] Preferably, the ship lift 2 is a fully balanced vertical ship lift, its civil engineering structure comprising four towers, a ship carriage 2a positioned between the towers, and a drive mechanism for driving the ship carriage 2a up and down. Both sides of the ship carriage 2a are provided with doors that can be opened for docking. Furthermore, the main structure of the fully balanced vertical ship lift described in this patent can be replaced by other types of ship lift main structures capable of simultaneous docking with both upper and lower lockheads. Maintenance gates, auxiliary lock chambers, and other facilities can be installed in the upstream and downstream pilot channels as needed.

[0032] Preferably, the ship lift 2 is equipped with four gates, including an upstream upper gate 2b located upstream, an upstream lower gate 2c located downstream, an upstream upper gate 2d located upstream, and a downstream lower gate 2e located downstream. In this embodiment, each gate is equipped with a conventional gate operating door, which can be adjusted in height according to the water level via a hydraulic hoist. During docking, the upper gate can be opened to connect the ship compartment 2a with the corresponding pilot channel.

[0033] Preferably, the upstream straight pilot channel 3 is connected to the upstream upper gate 2b; and the downstream straight pilot channel 6 is connected to the downstream lower gate 2e.

[0034] Preferably, after the upstream ship-turning guide channel 4 bypasses the tower column, it turns around and connects with the upstream lower lock head 2c; the area where the direction is turned is the upstream ship-turning area 4a.

[0035] Preferably, the upstream straight pilot channel 3 and the upstream reverse ship pilot channel 4 are overhead arranged by multiple supporting structures 5, and the parts of the supporting structures 5 spanning the downstream straight pilot channel 6 and the downstream reverse ship pilot channel 7 are provided with gaps for ships to pass through.

[0036] Preferably, the upstream straight pilot channel 3 and the upstream reverse pilot channel 4 share a common intermediate retaining wall. In this embodiment, sharing the intermediate retaining wall can reduce the amount of construction work and save construction materials. Furthermore, in actual practice, the two upstream pilot channels can also be set up as two independent pilot channels without sharing the intermediate retaining wall, and their supporting structures can be set up separately.

[0037] Preferably, after the downstream ship-turning pilot channel 7 bypasses the tower column, it turns around and connects with the downstream upper lock head 2d; the area where the direction is turned is the downstream ship-turning area 7a.

[0038] The present invention also discloses a navigation method for transferring a ship into a box-type ship lift using the double-guideway arranged along the waterway, which comprises the following steps:

[0039] When a large number of ships need to queue up to pass through the ship lift 2, navigation is carried out by synchronous docking of the two sides of the ship carriage. Specifically:

[0040] S1: Downstream ships enter the upstream ship-turning pilot channel 4 in advance and queue up in sequence. The ship at the front of the queue adjusts its stern direction at the upstream ship-turning area 4a and waits for the ship to turn into the carriage; upstream ships enter the downstream ship-turning pilot channel 7 in advance and queue up in sequence. The ship at the front of the queue waits at the downstream ship-turning area 7a;

[0041] S2: When the ship-carrying compartment 2a reaches the upstream docking elevation (such as Figure 4 and 5 As shown in the figure), its upstream side is docked with the upstream upper lock head 2b, and its downstream side is docked with the upstream lower lock head 2c. Then the upstream ship in the ship holding compartment 2a sails out of the ship holding compartment 2a and sails to the upstream waters through the upstream straight pilot channel 3. At the same time, the ship waiting in the upstream reverse ship area 4a can reverse into the ship holding compartment 2a. After the ship enters and exits the compartment, the ship holding compartment 2a is simultaneously undocking with both ends, and the ship holding compartment 2a can move downward;

[0042] S3: When the ship-carrying compartment 2a descends and reaches the downstream docking elevation (such as Figure 6 and 7 As shown), its upstream side is docked with the downstream upper lock head 2d, and its downstream side is docked with the downstream lower lock head 2e. Then the downstream ship in the ship holding chamber 2a sails out of the ship holding chamber 2a and sails to the downstream waters through the downstream straight pilot channel 6. At the same time, the ship waiting in the downstream ship reversing area 7a can reverse into the ship holding chamber 2a. After the ship enters and exits the chamber, the ship holding chamber 2a is undocked from both ends at the same time, and the ship holding chamber 2a can move upward.

[0043] The above technical solution can be adjusted according to actual conditions. The straight pilot channel can be used for ships entering the cabin, and the reverse pilot channel can be used for ships reversing out of the cabin. Ships leaving the cabin will first reverse into the reverse area, adjust the bow direction, and then leave in the forward direction. Ship traction devices can be installed in the reverse area and the ship receiving area to enable ships to reverse into the cabin by traction, rather than relying on their own power.

[0044] The present invention also discloses a navigation method for the above-mentioned double-pilot channel ship-turning-entry-box ship lift arranged along the waterway, which includes the following steps: when the number of ships is small and there is no need to queue, navigation is carried out by adopting a single-sided docking method of the ship-holding box (that is, navigation by a conventional single-sided docking method of the ship-holding box), at this time, the upstream ship-turning pilot channel 4 and the downstream ship-turning pilot channel 7 are not put into use, and ships directly enter and exit the ship-holding box 2a through the upstream straight pilot channel 3 and the downstream straight pilot channel 6.

[0045] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The embodiments and features in the embodiments of this application may be arbitrarily combined with each other unless they conflict. The scope of protection of the present invention shall be the technical solutions described in the claims, including equivalent alternatives to the technical features of the technical solutions described in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
