Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy engineering, in particular to a navigation facility. BACKGROUND

[0002] In recent years, inland waterway transportation has been rapidly developed as a green and economical transportation mode. With the development trend of large-scale transportation ships and the implementation of the national high-grade waterway network planning, the grade of waterway planning in various regions is continuously improved. In particular, in the Yangtze River Delta and the North China Plain, the transportation system is well developed, and there are many highway and railway bridges crossing the river. In order to achieve balanced development of the comprehensive transportation system, the problem of insufficient navigation clearance height in the existing bridge area often occurs during the upgrading and reconstruction of inland waterways.

[0003] In order to solve the navigation-obstructing problem caused by insufficient navigation clearance height in the existing bridge area, the following methods are usually used:

[0004] (1) The existing bridge crossing the river is reconstructed to improve the navigation clearance height and meet the needs of ship navigation. However, the reconstruction of the bridge crossing the river requires huge investment and causes local traffic interruption. In particular, important bridges such as mainline railway bridges and highway bridges cannot be reconstructed due to the need for important transportation security. Therefore, navigation ships are required to limit the height of the bridge, which causes some large transport ships to be blocked, reduces the overall freight efficiency, and makes it difficult to fully realize the economic benefits of water transportation.

[0005] (2) Connection wharfs are set up on the upstream and downstream of the navigation-obstructing bridge to realize the transfer of goods or personnel through the bridge by land transportation. However, the transfer through the bridge is a discontinuous transportation mode, which has low efficiency and poor economy, and occupies a large amount of land resources. SUMMARY

[0006] The present application provides a navigation facility that can solve the navigation needs under the condition of height limitation of the existing bridge, and also meets the requirements of not affecting the normal use of the bridge, river flood discharge during flood season, fish migration, etc.

[0007] The present application provides a navigation facility, comprising:

[0008] a deep navigation channel formed at the bottom of the normal navigation channel and passing through the bridge crossing the river; and

[0009] a semi-submersible floating ship loader configured to float in the deep navigation channel with controllable water depth and used for carrying ships through the bridge crossing the river.

[0010] In the above-mentioned implementation process, a deep navigation channel is formed by deepening and dredging the bottom of the normal navigation channel under the built bridge across the navigation channel, and the semi-submersible floating ship loader is stationed in the deep navigation channel. The ship, especially the super-high ship, can safely pass through the bridge across the navigation channel in cooperation with the semi-submersible floating ship loader and the adjustment of the water depth of the semi-submersible floating ship loader. Exemplarily, when the super-high ship needs to pass through the bridge across the navigation channel, the semi-submersible floating ship loader adjusts its water depth to an appropriate degree according to the water depth of the super-high ship, and the super-high ship drives into the semi-submersible floating ship loader and is separated from the water area outside the semi-submersible floating ship loader. Then, the semi-submersible floating ship loader continues to adjust its water depth, and the super-high ship sinks with the semi-submersible floating ship loader. When the clearance height under the bridge across the navigation channel meets the passing requirement of the super-high ship, the semi-submersible floating ship loader carries the super-high ship to pass through the bridge across the navigation channel. After the whole passes through the bridge across the navigation channel, the semi-submersible floating ship loader adjusts its water depth to float to the state when the super-high ship enters the semi-submersible floating ship loader, the super-high ship safely drives out of the semi-submersible floating ship loader, completes the passing through the bridge across the navigation channel, and the semi-submersible floating ship loader is ready for the next time. It should be noted that the navigation facility solves the navigation obstruction problem caused by the insufficient clearance height of the bridge across the navigation channel, meets the requirements of not affecting the normal use of the bridge, river flood discharge in flood season, fish migration and the like, greatly increases the overall navigation efficiency and the safety of passing through the bridge of the bridge with limited clearance height, and has the characteristics of ecological friendliness and low maintenance cost.

[0011] In an optional embodiment, the semi-submersible floating ship loader comprises a semi-submersible floating caisson, a traveling system, a ballast system and a monitoring system.

[0012] The semi-submersible floating caisson floats in the deep navigation channel.

[0013] The traveling system is configured to drive the semi-submersible floating caisson to travel in the deep navigation channel.

[0014] The ballast system is configured to control the water depth of the semi-submersible floating caisson.

[0015] The monitoring system is configured to detect the water depth and height of the ship and control the ballast system.

[0016] In the process of the above implementation, when the ultra-high ship needs to pass through the bridge, the monitoring system works to identify the draft depth and height information of the ultra-high ship, and make scheduling instructions to control the ballast system to ballast the semi-submersible floating caisson to adjust the draft depth of the semi-submersible floating caisson, so as to ensure that the ultra-high ship safely enters the semi-submersible floating caisson, and the inside and outside of the semi-submersible floating caisson are separated, so that the ultra-high ship is separated from the water area outside the semi-submersible floating caisson; then the ballast system continues to ballast the semi-submersible floating caisson, and the ultra-high ship and the semi-submersible floating caisson are lowered to the clearance height synchronously to meet the bridge passing requirement of the ultra-high ship, and then the ballast system stops working, the travel system is started, the semi-submersible floating caisson carries the ultra-high ship to pass through the height-limited bridge, and after the semi-submersible floating caisson passes through the bridge and is braked to be stationary, the ballast system is started to be unloaded, the semi-submersible floating caisson is floated up, the ultra-high ship safely exits the semi-submersible floating caisson, and the bridge passing is completed; wherein the semi-submersible floating caisson can return to the initial position under the driving of the travel system.

[0017] In an optional embodiment, the semi-submersible floating caisson comprises a caisson body and a gate.

[0018] Both ends of the caisson body are provided with the gate.

[0019] The monitoring system is further configured to detect the water level inside and outside the caisson body.

[0020] In the process of the above implementation, the gate blocks water, when the gate is closed, water cannot enter or exit the caisson body, so that the inside of the caisson body becomes an independent water area for the ultra-high ship to float, and when the gate is opened, the inside of the caisson body is connected with the outside water area to release the ship; for example, when the non-ultra-high ship needs to pass through the bridge, the gates on both sides of the caisson body are opened, and the non-ultra-high ship directly travels without affecting the fast navigation of the ship, thereby greatly improving the overall navigation efficiency of the height-limited bridge area; when the ultra-high ship needs to pass through the bridge, the monitoring system detects the water level information inside and outside the caisson body, and gradually opens the upstream gate or an additional water conveying system to fill water into the caisson body to make the water level inside and outside the caisson body level, and then opens the upstream gate to ensure that the ultra-high ship stably enters the caisson body, after the caisson body carries the ultra-high ship to pass through the bridge, the caisson body floats up, and after the monitoring system detects that the water level inside and outside the caisson body is level, the downstream gate is opened, and the ultra-high ship smoothly exits. For example, the gate type can adopt a miter gate or a triangular gate, and the opening direction is outward; wherein the miter gate can effectively adjust the water head difference inside and outside the gate of the caisson body, and reduce the width of the caisson body.

[0021] In an optional embodiment, the caisson body is formed with a flow passage, and the flow passage is communicated with the upstream side and the downstream side of the caisson body.

[0022] In the implementation process, the over-flow channel is used to reduce the resistance of the caisson body during driving, and water flow can flow through the over-flow channel; for example, the over-flow channel includes a guide channel formed in the inner wall of the caisson body, and a guide hole formed in the outer side of the caisson body.

[0023] In an optional embodiment, the caisson body is provided with an auxiliary air bag, which is located in the over-flow channel.

[0024] The auxiliary air bag is configured to be controllably inflated and deflated.

[0025] In the implementation process, the auxiliary air bag is used to improve the working efficiency of the ballast system and reduce the time of the super-high ship passing through once; when the caisson body is floated by the ballast system, the inflation and deflation of the auxiliary air bag can improve the floating speed; for example, after the semi-submersible floating caisson as a whole passes through the cross-bridge and is braked to be stationary, the ballast system is unloaded, the auxiliary air bag is inflated, thereby improving the overall buoyancy, so that the semi-submersible floating caisson and the super-high ship can quickly float up; when the caisson body needs to sink or drive, the auxiliary air bag is deflated to reduce the volume, so as not to occupy the over-flow channel, and to ensure the sinking speed and driving speed.

[0026] In an optional embodiment, the caisson body is provided with a mooring device for fixing the ship.

[0027] In the implementation process, when the super-high ship enters the caisson body, it is connected with the mooring device to maintain the relative position with the caisson body, so as to ensure that the semi-submersible floating caisson stably carries the ship; for example, the mooring device includes a plurality of fixed mooring hooks arranged on the inner wall of the caisson body in the horizontal and height directions, or a plurality of floating mooring columns arranged on the inner wall of the caisson body in the horizontal direction; the plurality of fixed mooring hooks or floating mooring columns are respectively connected with the ship, which is beneficial to the stability of the connection between the ship and the caisson body, and ensures that the ship remains stationary relative to the caisson body, which is beneficial to the semi-submersible floating caisson stably carrying the super-high ship through the cross-bridge.

[0028] In an optional embodiment, the ballast system includes a ballast water device and / or a movable counterweight device.

[0029] In the implementation process, the ballast system can include a ballast water device, a movable counterweight device, or a combination of the two. The ballast water device acts on the semi-submersible floating caisson to ballast water, which can be conveniently and quickly obtained from the surrounding; the movable counterweight device is used to movably ballast the semi-submersible floating caisson, so that it can quickly sink, which is beneficial to the efficiency of ship navigation.

[0030] In an optional embodiment, the navigation facility further includes a side guide wall arranged in the width range of the navigation hole of the cross-bridge and extending along the length direction of the deep navigation channel.

[0031] The semi-submersible floating caisson is between two side guide walls;

[0032] The semi-submersible floating caisson is provided with a guide device for cooperating with the side guide walls.

[0033] In the implementation process, the side guide walls divide the channel of the semi-submersible floating caisson, ensuring the orderly passage of the ship; when the semi-submersible floating ship loader carries the ship, the guide device cooperates with the side guide walls to realize the limiting, ensuring the semi-submersible floating ship loader to pass along the correct channel, avoiding the situation that the semi-submersible floating ship loader deviates from the channel and causes an accident, at the same time, the guide device and the side guide wall cooperate with each other, which is beneficial to the smooth progress of the semi-submersible floating ship loader, avoiding left-right translation and rolling; it should be noted that, for example, the side guide wall can adopt a portal structure with a relatively small overall width, a cross brace is arranged in the middle to enhance the overall strength, and a pile foundation is arranged at the lower part of the portal to ensure the strength and stability of the side guide wall.

[0034] In an optional embodiment, the length of the deep navigation channel on each side of the navigation bridge is not less than 1.5 times the length of the semi-submersible floating ship loader.

[0035] The length of the side guide wall on each side of the navigation bridge is not less than the length of the deep navigation channel on each side of the navigation bridge.

[0036] The deep navigation channel has a dredging depth that is not less than the sum of the normal passage height value of the channel design ship type, the thickness of the bottom plate of the semi-submersible floating ship loader, and a safety reserve depth.

[0037] In the implementation process, the length of the deep navigation channel and the side guide wall, and the length of the deep navigation channel and the side guide wall on each side of the navigation bridge are limited, which ensures the safe docking of the semi-submersible floating ship loader and the super-high ship, and ensures the safe carrying of the semi-submersible floating ship loader to pass through the navigation bridge.

[0038] In an optional embodiment, the traveling system includes a traction trolley, the traction trolley is arranged on the side guide wall, and the traction trolley pulls the semi-submersible floating caisson.

[0039] In the implementation process, the semi-submersible floating caisson is pulled by the traction trolley on the side guide wall to run between the two side guide walls, which is beneficial to the safe driving of the semi-submersible floating caisson; at the same time, the traction trolley has low maintenance cost, which is beneficial to the control of the cost of navigation facilities.

[0040] In an optional embodiment, the traveling system can include an engine and a propeller arranged on the semi-submersible floating caisson. The semi-submersible floating caisson automatically travels through the engine and the propeller. BRIEF DESCRIPTION OF DRAWINGS

[0053] The technical solutions in the present application will be described below with reference to the drawings.

[0054] The present embodiment provides a navigation facility which can solve the navigation needs under the height limit of the built bridge, and also meet the requirements of not affecting the normal use of the bridge, river flood discharge during flood season, fish migration, etc.

[0055] Please refer to Figures 1-4 , Figure 1 Fig. 2 is a schematic view of a transverse section of the navigation facility in the present embodiment, Figure 2 Fig. 3 is a schematic view of navigation of an ultra-high ship in the present embodiment, Figure 3 Fig. 4 is a schematic view of a semi-submersible floating ship loader 11 in the present embodiment, Figure 4 Fig. 5 is a top view of the semi-submersible floating ship loader 11 in the present embodiment. It should be noted that in Figure 1 Fig. 6 shows a ship located in the semi-submersible floating caisson 12 in the form of an arrow plus "A". In Figure 2 Fig. 7 shows an ultra-high ship in the form of an arrow plus "B".

[0056] The navigation facility includes a deep navigation channel 10 and a semi-submersible floating ship loader 11.

[0057] The deep navigation channel 10 is formed at the bottom 10a of the normal navigation channel and passes through the crossing bridge 10b.

[0058] The semi-submersible floating ship carrier 11 is configured to float controllably in the deep navigation channel 10 and to carry the ship through the over-bridge 10b.

[0059] In the above-mentioned process, the deep navigation channel 10 is formed by deepening the normal navigation channel 10a under the over-bridge 10b, and the semi-submersible floating ship carrier 11 is stationed in the deep navigation channel 10. The ship, especially the super-high ship, can safely pass through the over-bridge 10b in cooperation with the semi-submersible floating ship carrier 11 and the adjustment of the water depth of the semi-submersible floating ship carrier 11. For example, when the super-high ship needs to pass through the over-bridge 10b, the semi-submersible floating ship carrier 11 adjusts its water depth to an appropriate level according to the water depth of the super-high ship, and then the super-high ship enters the semi-submersible floating ship carrier 11 and is separated from the water outside the semi-submersible floating ship carrier 11. Subsequently, the semi-submersible floating ship carrier 11 continues to adjust its water depth, and the super-high ship sinks with the semi-submersible floating ship carrier 11. When the clearance height under the over-bridge 10b satisfies the passing of the super-high ship, the semi-submersible floating ship carrier 11 carries the super-high ship through the over-bridge 10b. After the whole passes through the over-bridge 10b, the semi-submersible floating ship carrier 11 adjusts its water depth to the state when the super-high ship enters the semi-submersible floating ship carrier 11, and the super-high ship safely exits the semi-submersible floating ship carrier 11, completing the passing of the over-bridge 10b. The semi-submersible floating ship carrier 11 is ready for the next carrying. It should be noted that the navigation facility solves the navigation problem caused by the insufficient clearance height of the over-bridge 10b, and meets the requirements of not affecting the normal use of the bridge, river flood discharge in flood season, fish migration, etc. It greatly increases the overall navigation efficiency and safety of passing through the bridge of the existing limited clearance bridge, and has the characteristics of ecological friendliness and low maintenance cost.

[0060] It should be noted that the semi-submersible floating ship carrier 11 is shown in the process of carrying the super-high ship to sink, and the process of carrying the super-high ship to float after passing through the over-bridge 10b. Figure 2

[0061] In the present disclosure, the semi-submersible floating ship carrier 11 includes a semi-submersible floating caisson 12, a traveling system 13, a ballast system 14, and a monitoring system.

[0062] The semi-submersible floating caisson 12 floats in the deep navigation channel 10. The traveling system 13 is configured to drive the semi-submersible floating caisson 12 to travel in the deep navigation channel 10. The ballast system 14 is configured to control the water depth of the semi-submersible floating caisson 12. The monitoring system is configured to detect the water depth and height of the ship and control the ballast system 14.

[0063] ​In the process of the above implementation, when the ultra-high ship passes through the cross-navigable bridge 10b, the monitoring system works to identify the draft and height information of the ultra-high ship, and gives a dispatch instruction. The ship lock operation dispatch system controls the ballast system 14 to ballast the semi-submersible floating caisson 12 to adjust its draft, so as to ensure that the ultra-high ship safely enters the semi-submersible floating caisson 12. The inside and outside of the semi-submersible floating caisson 12 are separated, so that the ultra-high ship is separated from the water area outside the semi-submersible floating ship loader 11. Then the ballast system 14 continues to ballast the semi-submersible floating caisson 12. After the ultra-high ship and the semi-submersible floating caisson 12 are synchronously lowered to a clearance height to meet the cross-navigable bridge 10b passing through, the ballast system 14 stops working, the travel system 13 is started, the semi-submersible floating caisson 12 carries the ultra-high ship to pass through the height-limited cross-navigable bridge 10b, and after the semi-submersible floating caisson 12 as a whole passes through the cross-navigable bridge 10b and is braked to be stationary, the ballast system 14 is started to be unloaded, the semi-submersible floating caisson 12 is floated up, the ultra-high ship safely exits the semi-submersible floating caisson 12, and the cross-navigable bridge 10b passing through is completed. The semi-submersible floating caisson 12 can return to the initial position under the driving of the travel system 13.

[0064] It should be noted that the monitoring system can include a sensor capable of measuring the draft of the ship, such as a water level gauge.

[0065] It should be noted that in the present disclosure, referring to Figure 1 The navigation facility further includes side guide walls 15 arranged within the navigation hole width range of the cross-navigable bridge 10b and extending along the length direction of the deep navigation channel 10. The semi-submersible floating caisson 12 is between the two side guide walls 15. The semi-submersible floating caisson 12 is provided with a guide device 16 for cooperation with the side guide walls 15.

[0066] In the process of the above implementation, the side guide walls 15 divide the navigation channel of the semi-submersible floating caisson 12 to ensure the orderly passage of the ship. When the semi-submersible floating ship loader 11 carries the ship, the guide device 16 cooperates with the side guide walls 15 to achieve limiting, so as to ensure that the semi-submersible floating ship loader 11 passes along the correct navigation channel, avoid the situation that the semi-submersible floating ship loader 11 deviates from the navigation channel and causes an accident, and at the same time, the guide device 16 cooperates with the side guide walls 15, which is beneficial to the smooth progress of the semi-submersible floating ship loader 11 and avoids left-right translation and rolling. It should be noted that the side guide walls 15 can be a portal type structure with a small overall width, a cross brace is arranged in the middle to enhance the overall strength, and a pile foundation is arranged at the lower part of the portal to ensure the strength and stability of the side guide walls 15. It should be noted that the guide device 16 can include multiple groups of spherical mechanisms arranged on the outer side of the semi-submersible floating caisson 12.

[0067] In the present disclosure, the length of the deep navigation channel 10 on each side beyond the length of the cross navigation bridge 10b is not less than 1.5 times the length of the semi-submersible floating ship loader 11. The length of the side guide wall 15 on each side beyond the length of the cross navigation bridge 10b is not less than the length of the deep navigation channel 10 on each side beyond the length of the cross navigation bridge 10b.

[0068] The deep navigation channel 10 has a depth that is not less than the sum of the normal navigation passage super-elevation value of the channel design ship type, the bottom plate thickness of the semi-submersible floating ship loader 11, and a safety reserve depth.

[0069] In the above-mentioned implementation process, the length of the deep navigation channel 10 and the side guide wall 15, and the length of the deep navigation channel 10 and the side guide wall 15 on each side beyond the length of the cross navigation bridge 10b are limited, which ensures the safe docking of the semi-submersible floating ship loader 11 and the super-elevation ship, and ensures the safe transportation of the semi-submersible floating ship loader 11 and the super-elevation ship through the cross navigation bridge 10b.

[0070] In other specific embodiments, the length of the deep navigation channel 10 and the side guide wall 15, and the depth of the deep navigation channel 10 are not limited, and the normal navigation of the super-elevation ship is sufficient.

[0071] It should be noted that the deep navigation channel 10 and the bottom 10a of the normal navigation channel are naturally connected through an underwater vertical retaining wall or a slope that meets the natural channel bottom quality itself stability.

[0072] It should be noted that the deep navigation channel 10 and the side guide wall 15 can be designed as single-line or multi-line to meet the navigation of one or multiple ships. See Figure 1 , Figure 1 Exemplarily, the deep navigation channel 10 and the side guide wall 15 are designed as two-line, that is, they can meet the navigation of two ships at the same time.

[0073] See Figure 3 and Figure 4 In the present disclosure, the semi-submersible floating caisson 12 includes a caisson body 17 and a gate 18. The caisson body 17 is provided with a gate 18 at both ends. The monitoring system is also configured to detect the water level inside and outside the caisson body 17.

[0074] In the implementation process, the gate 18 functions as a water barrier. When the gate 18 is closed, water cannot enter or exit the caisson body 17, so that the caisson body 17 internally forms an independent water area for suspending the super-high ship. When the gate 18 is opened, the inside of the caisson body 17 is in communication with the outside water area, and the ship is released. Exemplarily, when a non-super-high ship needs to pass through the cross-river bridge 10b, the two side gates 18 of the caisson body 17 are opened, and the non-super-high ship directly drives through, without affecting the rapid navigation of the ship, and greatly improving the overall navigation efficiency of the height-limited bridge area. When a super-high ship needs to pass through the cross-river bridge 10b, the monitoring system can detect the water level information inside and outside the caisson body 17, and gradually open the upstream side gate 18 or an additional water conveying system to fill water into the caisson body 17, so that the water levels inside and outside the caisson body 17 are level, and then the upstream side gate 18 is opened, to ensure that the super-high ship smoothly enters the caisson body 17. After the caisson body 17 carries the super-high ship to pass through the cross-river bridge 10b, the caisson body 17 floats up. When the monitoring system detects that the water levels inside and outside the caisson body 17 are level, the downstream side gate 18 is opened, and the super-high ship smoothly drives out. Exemplarily, the gate 18 can adopt a miter gate 18 or a triangular gate 18, and the opening direction is outward. The miter gate 18 can effectively adjust the water head difference inside and outside the gate 18 of the caisson body 17, and reduce the width of the caisson body 17.

[0075] In the present disclosure, the caisson body 17 is formed with a flow passage 19, which is in communication with the upstream side and the downstream side of the caisson body 17.

[0076] In the implementation process, the flow passage 19 is used to reduce the resistance of the caisson body 17 during driving, and water flow can flow through the flow passage 19. Exemplarily, the flow passage 19 includes a flow guide passage 20 formed in the inner wall of the caisson body 17, and a flow guide hole 21 formed in the outer vertical surface of the caisson body 17.

[0077] In the present disclosure, the caisson body 17 is provided with an auxiliary air bag 22, which is located in the flow passage 19. The auxiliary air bag 22 is configured to be controllably inflated and deflated.

[0078] In the implementation process, the auxiliary air bag 22 is used to improve the working efficiency of the ballast system 14 and reduce the time of a single passage of the super-high ship. When the caisson body 17 is floated by the ballast system 14, the inflation and deflation of the auxiliary air bag 22 can improve the floating speed. For example, after the semi-submersible floating caisson 12 as a whole passes through the cross-river bridge 10b and is braked to be stationary, the ballast system 14 is unloaded, and the auxiliary air bag 22 is inflated, thereby improving the overall buoyancy, so that the semi-submersible floating caisson 12 and the super-high ship quickly float up. When the caisson body 17 needs to sink or drive, the auxiliary air bag 22 is deflated to reduce the volume, so as not to occupy the flow passage 19, and to ensure the sinking speed and driving speed.

[0079] In the present disclosure, referring to Figure 3 and Figure 4 , the caisson body 17 is configured with a mooring device 23 for fixing the ship.

[0080] In the implementation process described above, when the ultra-high ship enters the caisson body 17, it is connected with the mooring device 23, and the relative position with the caisson body 17 is maintained, so as to ensure that the semi-submersible floating caisson 12 stably carries the ship. Exemplarily, the mooring device 23 includes a plurality of fixed mooring hooks arranged on the inner wall of the caisson body 17 in the horizontal and height directions.
