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 perpendicular to a waterway and a navigation method thereof. 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 arranged perpendicular to the waterway and a navigation method thereof, which can greatly reduce the waiting time between ships leaving and entering the compartment, thereby significantly improving the navigation efficiency of the ship lift.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a double-pilot channel ship lift arranged perpendicular to the waterway, including a ship lift located on the downstream side of the dam, an upstream entrance pilot channel and an upstream exit pilot channel are respectively provided between the upper part of the ship lift and the upstream water area of the dam, and a downstream entrance pilot channel and a downstream exit 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-carrying box is arranged perpendicular to the natural waterway direction.

[0007] Preferably, the upstream entrance pilot channel, upstream exit pilot channel, downstream entrance pilot channel and downstream exit pilot channel all include vertical channels and transverse channels, wherein the vertical channels are perpendicular to the direction of the natural channels and the transverse channels are parallel to the direction of the natural channels.

[0008] Preferably, an upstream entry turning area is set at the intersection of the vertical channel and the transverse channel of the upstream entry pilot channel, an upstream exit turning area is set at the intersection of the vertical channel and the transverse channel of the upstream exit pilot channel, a downstream entry turning area is set at the intersection of the vertical channel and the transverse channel of the downstream entry pilot channel, and a downstream exit turning area is set at the intersection of the vertical channel and the transverse channel of the downstream exit pilot channel.

[0009] Preferably, the ship lift is provided with four lock heads, including an upstream right bank lock head located on the right bank side at the upstream elevation, an upstream left bank lock head located on the left bank side at the upstream elevation, a downstream right bank lock head located on the right bank side at the downstream elevation, and a downstream left bank lock head located on the left bank side at the downstream elevation.

[0010] Preferably, the vertical channel of the upstream inlet pilot channel is connected to the upstream right bank gate, the vertical channel of the upstream outlet pilot channel is connected to the upstream left bank gate, the vertical channel of the downstream inlet pilot channel is connected to the downstream left bank gate, and the vertical channel of the downstream outlet pilot channel is connected to the downstream right bank gate.

[0011] Preferably, the upstream entry pilot channel and the upstream exit pilot channel are overhead arranged by a plurality of supporting structures, and the parts of the supporting structures spanning the downstream entry pilot channel and the downstream exit pilot channel are provided with gaps for ships to pass through.

[0012] In addition, 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] S1: Downstream ships enter the upstream entrance pilot channel in advance and queue up in order. The ship at the front of the queue adjusts its direction at the upstream entrance turning area and waits for entry. Upstream ships enter the downstream entrance pilot channel in advance and queue up in order. The ship at the front of the queue waits at the downstream entrance turning area.

[0014] S2: When the ship carriage reaches the upstream docking elevation, its right bank side docks with the upstream right bank gate, and its left bank side docks with the upstream left bank gate. Then the upstream ship in the ship carriage sails out of the ship carriage and enters the upstream exit turning area. After adjusting the direction, it sails from the upstream exit pilot channel to the upstream waters. At the same time, ships waiting in the upstream entrance turning area can enter the ship carriage. After the ships have completed the entry and exit, the ship carriage is undocking with the gates at both ends, and the ship carriage can move downward.

[0015] S3: When the ship-carrying compartment descends to the downstream docking elevation, its right bank side docks with the downstream right bank gate head, and its left bank side docks with the downstream left bank gate head. Then the downstream ship in the ship-carrying compartment sails out of the ship-carrying compartment and enters the downstream exit turning area. After adjusting the direction, it sails from the downstream exit pilot channel to the downstream waters. At the same time, the ships waiting in the downstream entrance turning area enter the ship-carrying compartment. After the ships complete the entry and exit, the ship-carrying compartment is undocking from the gate heads at both ends, and the ship-carrying compartment 2a can move upward.

[0016] Preferably, after docking upstream or downstream, if only the ship enters the compartment but not leaves, the exit pilot channel side may not be docked; if only the ship leaves the compartment but not enters, the entrance pilot channel side may not be docked.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention provides dual pilot channels and synchronized docking on both sides of the ship lift, so that after a ship leaves the lift, the next ship can enter the lift immediately, thereby significantly reducing the waiting time between ships leaving and entering the lift. When a large number of ships need to queue up to pass through the lift, the navigation efficiency of the lift can be significantly improved compared to a conventional lift with only one pilot channel upstream and downstream.

[0019] 2. According to the present invention, after docking at upstream or downstream, if only a ship enters the compartment but does not leave, the outgoing compartment pilot channel side may not be docked; if only a ship leaves the compartment but does not enter, the incoming compartment pilot channel side may not be docked, which can streamline the entire operation process and further save time.

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 7 As shown, a dual-channel ship lift arranged perpendicular to the waterway includes a ship lift 2 located on the downstream side of a dam 1. An upstream inlet pilot channel 3 and an upstream outlet pilot channel 4 are respectively provided between the upper portion of the ship lift 2 and the upstream waters of the dam 1. A downstream inlet pilot channel 6 and a downstream outlet pilot channel 7 are respectively provided between the lower portion of the ship lift 2 and the downstream waters of the dam 1.

[0029] Preferably, the ship lift 2 is a fully balanced vertical ship lift. Its civil engineering structure includes four towers, with a ship compartment 2a and a drive mechanism for moving the compartment 2a up and down located between the towers. The compartment 2a is flanked by doors that can be opened for docking. 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 the upper and lower lockheads. Furthermore, maintenance gates, auxiliary lock chambers, and other facilities can be installed in the upstream and downstream pilot channels as needed.

[0030] Preferably, the ship-carrying compartment 2a is arranged perpendicular to the natural channel direction. Furthermore, in addition to being arranged perpendicular to the natural channel direction, the ship-carrying compartment 2a can also be arranged at a certain angle to the original channel as needed.

[0031] Preferably, the upstream entrance pilot channel 3, upstream exit pilot channel 4, downstream entrance pilot channel 6 and downstream exit pilot channel 7 all include vertical channels and transverse channels, wherein the vertical channels are perpendicular to the direction of the natural channels and the transverse channels are parallel to the direction of the natural channels.

[0032] Preferably, an upstream entry turning area 3a is set at the intersection of the vertical channel and the transverse channel of the upstream entry pilot channel 3, an upstream exit turning area 4a is set at the intersection of the vertical channel and the transverse channel of the upstream exit pilot channel 4, a downstream entry turning area 6a is set at the intersection of the vertical channel and the transverse channel of the downstream entry pilot channel 6, and a downstream exit turning area 7a is set at the intersection of the vertical channel and the transverse channel of the downstream exit pilot channel 7.

[0033] Preferably, the ship lift 2 is provided with four gates, including an upstream right bank gate 2b located on the right bank side at the upstream elevation, an upstream left bank gate 2c located on the left bank side at the upstream elevation, a downstream right bank gate 2d located on the right bank side at the downstream elevation, and a downstream left bank gate 2e located on the left bank side at the downstream elevation.

[0034] Preferably, the vertical channel of the upstream inlet pilot channel 3 is connected to the upstream right bank gate 2b, the vertical channel of the upstream outlet pilot channel 4 is connected to the upstream left bank gate 2c, the vertical channel of the downstream inlet pilot channel 6 is connected to the downstream left bank gate 2e, and the vertical channel of the downstream outlet pilot channel 7 is connected to the downstream right bank gate 2d. In this embodiment, a conventional gate working door is provided in each gate, which can be adjusted in height according to the water level by a hydraulic hoist. When docking, the upper door can be opened to connect the ship-carrying compartment 2a with the corresponding pilot channel.

[0035] In addition, in this embodiment, the left and right bank position relationship of the entrance and exit pilot channels can be interchanged according to different navigation habits or regulations, that is, the upstream entrance pilot channel and the downstream exit pilot channel are set on the left bank side, and the upstream exit pilot channel and the downstream entrance pilot channel are set on the right bank side.

[0036] Preferably, the upstream inlet pilot channel 3 and the upstream outlet pilot channel 4 are overhead arranged by multiple supporting structures 5, and the parts of the supporting structures 5 spanning the downstream inlet pilot channel 6 and the downstream outlet pilot channel 7 are provided with gaps for ships to pass through.

[0037] In addition, 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:

[0038] S1: Downstream ships enter the upstream entry pilot channel 3 in advance and queue up in sequence. The ship at the front of the queue adjusts its direction at the upstream entry turning area 3a and waits for entry. Upstream ships enter the downstream entry pilot channel 6 in advance and queue up in sequence. The ship at the front of the queue waits at the downstream entry turning area 6a.

[0039] S2: When the ship carriage 2a reaches the upstream docking elevation, its right bank side docks with the upstream right bank gate 2b, and its left bank side docks with the upstream left bank gate 2c. Then the upstream ship in the ship carriage 2a sails out of the ship carriage 2a and enters the upstream exit turning area 4a. After adjusting the direction, it sails from the upstream exit pilot channel 4 to the upstream waters. At the same time, ships waiting in the upstream entrance turning area 3a can sail into the ship carriage 2a. After the ships enter and exit the ship carriage, the ship carriage 2a is simultaneously undocking from the gates at both ends, and the ship carriage 2a can move downward.

[0040] S3: When the ship-carrying compartment 2a descends to the downstream docking elevation, its right bank side docks with the downstream right bank gate 2d, and its left bank side docks with the downstream left bank gate 2e. Then the downstream ship in the ship-carrying compartment 2a sails out of the ship-carrying compartment 2a and enters the downstream exit turning area 7a. After adjusting the direction, it sails from the downstream exit pilot channel 7 to the downstream waters. At the same time, the ship waiting in the downstream entrance turning area 6a enters the ship-carrying compartment 2a. After the ships complete the entry and exit, the ship-carrying compartment 2a is simultaneously undocking from the gates at both ends, and the ship-carrying compartment 2a can move upward.

[0041] Preferably, after docking upstream or downstream, if only the ship enters the compartment but not leaves, the exit pilot channel side may not be docked; if only the ship leaves the compartment but not enters, the entrance pilot channel side may not be docked.
