Description

Technical Field

[0001] The present invention belongs to the field of ship lock facility protection for water transport engineering, and in particular relates to a floating direction-adjusting and anti-collision device and method for ships entering and exiting a lock through a navigation wall section. Background Art

[0002] The upstream and downstream navigation walls of a ship lock are directly connected to the gates of the lock or ship lift. Their primary function is to guide ships safely and smoothly into and out of the lock or ship lift. When ships pass through these walls, collisions with the walls or even oblique crossings into the approach channel can occur frequently due to mishandling, excessive crosscurrents, excessive speed, or narrow approach channels. This is particularly common in narrow bends and rapids. Because fixed navigation walls are suitable for most situations, they were the primary design used in early ship lock approach channel navigation wall designs.

[0003] In order to improve the situation of navigation walls being hit by ships, domestic locks have adopted anti-collision measures such as installing steel guards and traditional rubber fenders on the lock walls, which have protected the hydraulic structures to a certain extent. However, when anti-collision facilities such as steel guards and rubber fenders collide with ships, since the steel guards are fixed on the lock walls, the collision is basically a rigid collision, which causes great damage to the protection facilities and ships, resulting in poor durability of the protection facilities. It is difficult to repair the protection facilities after collision, and the ship needs to be stopped for on-site inspection and maintenance, which has a great impact on navigation, especially in river sections with busy shipping, where it is not allowed to stop for inspection and maintenance easily. Summary of the Invention

[0004] In order to solve the current technical problems, the main purpose of the present invention is to provide a floating direction-adjusting anti-collision device and method for ships entering and exiting the navigation wall section. The anti-collision device can protect the navigation wall and assist ships in adjusting their directions, reduce the damage to ships caused by rigid collisions, extend the service life of anti-collision facilities, and at the same time realize the rapid replacement of anti-collision devices, reduce the impact on navigation, and save anti-collision materials.

[0005] In order to achieve the above technical features, the object of the present invention is achieved as follows: a floating steering and anti-collision device for ships entering and exiting a lock in a navigation wall section comprises floating steering and anti-collision units arranged at intervals along the lock wall of the navigation wall;

[0006] Each floating direction-adjusting and anti-collision unit includes a buoy bracket body. The upper and lower ends of the buoy bracket body are respectively equipped with bracket guide wheel groups that cooperate with the gate wall guide rails. The outer side wall of the bracket guide wheel group is hinged with a fender base through multiple dampers. An elastic buffer mechanism and a telescopic guide mechanism are arranged between the fender base and the buoy bracket body. A rubber fender body is fixedly installed on the outer wall of the fender base. The bottom end of the buoy bracket body is hinged with a buoy through a connecting rod. The buoy is slidably arranged inside the navigation wall gate wall through the buoy guide wheel group.

[0007] Preferably, the bracket guide wheel group includes a symmetrically arranged first transverse roller and a first longitudinal roller, which respectively roll with the transverse and longitudinal inner walls of the gate wall guide rail, and enable the buoy bracket body to only move up and down along the gate wall guide rail.

[0008] Preferably, a first damper ear seat is symmetrically fixed on the outer wall of the bracket guide wheel group, a corresponding damper pin is hinged on the base of the damper, and both ends of the damper pin are fixedly connected to the first damper ear seat by long bolts.

[0009] Preferably, the elastic buffer mechanism includes a plurality of first spring bases fixed to the back of the fender base, a spring is correspondingly mounted on the first spring base, the other end of the spring is positioned inside the second spring base, and the second spring base is fixed inside the buoy support body;

[0010] The damper restrains the spring from falling off the first spring base and the second spring base.

[0011] Preferably, the telescopic guide mechanism includes a guide rod symmetrically fixed to the back of the fender base, the other end of the guide rod passes through a guide sleeve, and the guide sleeve is fixed to the outer wall of the buoy support body.

[0012] Preferably, when the spring is compressed to its maximum, the guide sleeve still has a certain margin between it and the guide rod; when the spring is extended to its maximum, a portion of the guide rod is still located in the guide sleeve, so that the guide rod can move horizontally in a direction perpendicular to the water flow while bearing the gravity of the rubber fender body and the fender base itself.

[0013] Preferably, the outer contour of the rubber fender body is a cylindrical surface, a hollow cylinder is processed in the center of the rubber fender body, and lugs are provided on both sides of the bottom end of the rubber fender body, which are fixedly connected to the fender base by connecting bolts and nuts.

[0014] Preferably, the back of the fender base is provided with multiple groups of symmetrically arranged second damper ears, the end of the damper piston rod is hinged with a corresponding damper pin, and the two ends of the damper pin are fixedly connected to the second damper ears by long bolts.

[0015] Preferably, the buoy includes an upper buoy body, an upper portion of which is mounted a buoy guide wheel assembly, the buoy guide wheel assembly comprising a second transverse roller and a second longitudinal roller symmetrically arranged, the second transverse roller and the second longitudinal roller respectively rollingly cooperating with the transverse and longitudinal inner walls of the gate wall guide rail, and enabling the buoy to move up and down only along the gate wall guide rail;

[0016] The buoy is provided with a buoy waterline;

[0017] A buoy support lug is provided on the top of the buoy support body;

[0018] A buoy lifting ring is provided on the top of the buoy;

[0019] The top end of the connecting rod is hingedly connected to the bottom end of the buoy support body through an upper fixed pin, and the bottom end of the connecting rod is hingedly connected to the top end of the buoy through a lower fixed pin;

[0020] The buoy support body adopts a box-type structure and is provided with a reinforcing plate inside.

[0021] Preferably, in another aspect, a method for operating a floating steering and anti-collision device for navigation wall sections of ships entering and exiting a lock is provided, comprising the following steps:

[0022] Step 1: Installation of floating steering and anti-collision unit:

[0023] Use hoisting equipment to hoist the buoy and buoy bracket body connected by connecting rods into the navigation wall, and ensure that the bracket guide wheel group and the buoy guide wheel group form a sliding guide fit with the gate wall guide rail;

[0024] Step 2: Floating and lifting of the floating direction adjustment and anti-collision unit:

[0025] After the entire floating steering and anti-collision unit is installed and arranged, the buoyancy of the water keeps the entire floating steering and anti-collision unit in a constant position relative to the water surface; the bracket guide wheel group and the buoy guide wheel group are used to overcome the friction with the gate wall guide rail to ensure smooth up and down movement;

[0026] Step 3, ship collision avoidance:

[0027] When a ship is sailing inside the lock chamber and is impacted by unstable water flow and collides with the lock wall, the ship will first collide with the rubber fender body. At this time, the rubber fender body absorbs energy by rubber extrusion, cushions the impact force, reduces collision noise and vibration, and protects the navigation wall hydraulic structure and the ship itself from damage;

[0028] At the same time, the rubber fender body will synchronously transfer the impact to the elastic buffer mechanism, which will be compressed to absorb the energy of the ship's collision or squeezing;

[0029] Step 4, recovery of ship position:

[0030] After the ship hits the rubber fender body, under the compression and buffering effect of the elastic buffer mechanism, the ship speed gradually drops to 0, and the elastic buffer mechanism slowly recovers, releasing energy and pushing the rubber fender body outward, thereby applying force to the ship in a gentle manner, so that the ship diagonally crossing the pilot channel can be straightened;

[0031] Step 5: Replacement of the floating steering and anti-collision unit:

[0032] When the anti-collision device is damaged, it is lifted out as a whole through the lifting lugs installed on the main body of the buoy bracket, replaced with spare parts, and then transported back to the yard for maintenance, so as to shorten the suspension maintenance time and reduce the impact on navigation.

[0033] The present invention has the following beneficial effects:

[0034] 1. The present invention makes full use of the performance of two different structures, rubber fender and spring, to double absorb and buffer the impact or extrusion energy of the ship, achieve better anti-collision effect, and effectively protect the navigation wall hydraulic structure and the ship itself from damage.

[0035] 2. The present invention utilizes the ability of the spring to compress and stretch. When the spring recovers its deformation, it exerts an outward force on the ship, thereby assisting the ship crossing the pilot channel to adjust its direction and allowing the ship to enter and exit the lock smoothly.

[0036] 3. The present invention utilizes a combined anti-collision mode of rubber fenders and springs, which can achieve a better shock absorption effect and reduce collision noise and vibration.

[0037] 4. The present invention utilizes the buoyancy of the water acting on the buoy as the lifting power source of the anti-collision device, which can well adapt to the situation where the water level of the pilot channel fluctuates greatly.

[0038] 5. The present invention utilizes the compressibility of the spring. When a ship collides with the anti-collision device, the anti-collision device can move within a certain range, thereby playing a better force-relieving role, better protecting the rubber fender and the ship itself, and avoiding serious damage.

[0039] 6. The anti-collision device of the present invention can be quickly repaired and replaced. The anti-collision device adopts a floating type that can be lifted up and down. It is not fixed on the gate wall. When repair is needed, it can be quickly lifted out in whole or in part and quickly replaced with spare parts, which greatly reduces the time of suspension of navigation for maintenance and reduces the impact on navigation.

[0040] 7. The present invention utilizes the buoyancy of the water acting on the buoy as the lifting power source of the anti-collision device, which can well adapt to the situation where the water level of the pilot channel fluctuates greatly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0052] Example 1:

[0053] See also Figure 1-8A floating steering and anti-collision device for ships entering and exiting a lock in a navigation wall section comprises floating steering and anti-collision units arranged at intervals along the navigation wall lock wall 28; each floating steering and anti-collision unit comprises a buoy bracket body 12, and the upper and lower ends of the buoy bracket body 12 are respectively provided with bracket guide wheel groups that cooperate with the lock wall guide rails 29, and a fender base 5 is hingedly connected to the outer wall of the bracket guide wheel group through a plurality of dampers 10, and an elastic buffer mechanism and a telescopic guide mechanism are provided between the fender base 5 and the buoy bracket body 12, and a rubber fender body 1 is fixedly installed on the outer wall of the fender base 5, and the bottom end of the buoy bracket body 12 is hingedly connected to a buoy 20 through a connecting rod 25, and the buoy 20 is slidably arranged inside the navigation wall lock wall 28 through the buoy guide wheel group. By adopting the above-mentioned floating direction-adjusting and anti-collision device, it is possible to protect the navigation wall and assist the ship in adjusting its direction, reduce the damage to the ship caused by rigid collision, extend the service life of the anti-collision facility, and realize the rapid replacement of the anti-collision device, reduce the impact on navigation, and save anti-collision materials.

[0054] During operation, the buoyancy of the buoy 20 maintains its relative position to the water surface. The support and buoy guide wheel assemblies are used to overcome friction between the mechanism and the gate wall guide rails 29, ensuring smooth up and down movement. The upper end of the connecting rod 25 is connected to the buoy support via a connecting pin, while the lower end is connected to the upper cylinder of the buoy via a connecting pin, forming a single unit with the buoy and buoy support.

[0055] Specifically, the floating steering and anti-collision unit can simultaneously meet three functions. First, it can float up and down with the water level of the channel, making it ideal for situations where the water level of the navigation wall pilot channel fluctuates greatly. Second, it utilizes a dual anti-collision structure of the rubber fender body 1 and the elastic buffer mechanism, which has better anti-collision capabilities. The anti-collision device can move within a certain range, playing a better force-relieving role, while effectively protecting the rubber fender and the ship itself, and avoiding serious collision damage. Third, the elastic buffer mechanism is used. By utilizing the elastic buffer mechanism's ability to recover after being compressed, it can push out a deviating ship and assist the ship in adjusting its direction.

[0056] Furthermore, the support guide wheel assembly includes a symmetrically arranged first transverse roller 14 and a first longitudinal roller 15, which respectively roll with the transverse and longitudinal inner walls of the gate wall guide rail 29, and enable the buoy support body 12 to move up and down only along the gate wall guide rail 29. The above-mentioned support guide wheel assembly plays a good guiding role, thereby ensuring smooth sliding inside the gate wall guide rail 29.

[0057] Furthermore, first damper lugs 17 are symmetrically fixed to the outer wall of the bracket guide wheel assembly, and corresponding damper pins 32 are hingedly connected to the base of the damper 10. The two ends of the damper pins 32 are fixedly connected to the first damper lugs 17 by long bolts 31. The above-mentioned first damper lugs 17 can achieve reliable hinged installation of the damper 10.

[0058] Furthermore, the elastic buffer mechanism includes multiple first spring bases 7 fixed to the back of the fender base 5. A spring 11 is mounted on each of the first spring bases 7. The other end of the spring 11 is positioned inside a second spring base 16, which is fixed inside the buoy support body 12. The damper 10 restrains the spring 11 from falling out of the first and second spring bases 7 and 16. The elastic buffer mechanism can be used to cushion the impact of a ship and restore the ship to its original position.

[0059] By utilizing the compressible properties of the spring, the anti-collision device can move within a certain range when it encounters a ship collision, thereby playing a better force unloading role, better protecting the rubber fender and the ship itself, and avoiding serious collision damage.

[0060] After the ship hits the compression spring, there is an outward pushing force on the ship during the process of the spring recovering its deformation, which helps the ship crossing the pilot channel diagonally to adjust its direction so that the ship can enter and exit the lock smoothly.

[0061] Furthermore, the telescopic guide mechanism includes a guide rod 6 symmetrically fixed to the back of the fender base 5. The other end of the guide rod 6 passes through a guide sleeve 18, which is fixed to the outer wall of the buoy support body 12. The telescopic guide mechanism can achieve telescopic guidance of the fender base 5, thereby ensuring its smooth extension and retraction.

[0062] Furthermore, when the spring 11 is compressed to its maximum, the guide sleeve 18 still has a certain amount of clearance from the guide rod 6. When the spring 11 is extended to its maximum, a portion of the guide rod 6 is still located within the guide sleeve 18, allowing the guide rod 6 to move horizontally in a direction perpendicular to the water flow while also bearing the weight of the rubber fender body 1 and the fender base 5. This dimensional structure effectively prevents the spring 11 from falling off and ensures that it can provide a good cushioning effect.

[0063] Furthermore, the outer contour of the rubber fender body 1 is a cylindrical surface, a hollow cylinder 2 is processed in the center of the rubber fender body 1, and ear plates 3 are provided on both sides of the bottom end of the rubber fender body 1. The ear plates 3 are fixedly connected to the fender base 5 by connecting bolts 4 and nuts 8.

[0064] Furthermore, the back of the fender base 5 is provided with multiple groups of symmetrically arranged second damper ears 8, and the end of the piston rod of the damper 10 is hinged with a corresponding damper pin 32, and the two ends of the damper pin 32 are fixedly connected to the second damper ears 8 by long bolts 31.

[0065] Furthermore, the buoy 20 includes an upper buoy body 21, and a buoy guide wheel assembly is installed on the upper part of the buoy upper body 21. The buoy guide wheel assembly includes a second transverse roller 24 and a second longitudinal roller 23 that are symmetrically arranged. The second transverse roller 24 and the second longitudinal roller 23 respectively roll with the transverse and longitudinal inner walls of the gate wall guide rail 29, so that the buoy 20 can only move up and down along the gate wall guide rail 29.

[0066] Furthermore, a buoy waterline 22 is provided on the buoy 20. The buoy waterline 22 facilitates displaying the draft position of the buoy 20.

[0067] Furthermore, the top of the buoy support body 12 is provided with a buoy support lifting lug 13. This facilitates the lifting of the buoy support body 12. If the anti-collision device is damaged, it can be lifted out of the vessel using the lifting lug installed on the buoy support, replaced with a spare part, and then transported back to the shipyard for repair. This significantly shortens downtime for repairs and minimizes the impact on navigation.

[0068] Furthermore, a buoy lifting ring 27 is provided on the top of the buoy 20. The buoy lifting ring 27 facilitates the lifting of the buoy 20. If the anti-collision device is damaged, it can be lifted out of the vessel using the lifting lugs installed on the buoy bracket, replaced with a spare part, and then transported back to the shipyard for repair, significantly shortening the downtime for repairs and minimizing the impact on navigation.

[0069] Furthermore, the top end of the connecting rod 25 is hingedly connected to the bottom end of the buoy bracket body 12 through the upper fixed pin 19, and the bottom end of the connecting rod 25 is hingedly connected to the top end of the buoy 20 through the lower fixed pin 26; the connection structure of the above-mentioned connecting rod 25 facilitates the hinge between the buoy bracket body 12 and the buoy 20.

[0070] Furthermore, the buoy support body 12 adopts a box-shaped structure and is provided with a reinforcing plate 30 inside. The reinforcing plate 30 enhances the structural strength and stability of the buoy support body 12.

[0071] Example 2:

[0072] Provide step 1, installation of floating steering and anti-collision unit:

[0073] Use hoisting equipment to hoist the buoy 20 and the buoy support body 12 assembled and connected by the connecting rod 25 into the navigation wall 28, and ensure that the support guide wheel group and the buoy guide wheel group form a sliding guide fit with the gate wall guide rail 29;

[0074] Step 2: Floating and lifting of the floating direction adjustment and anti-collision unit:

[0075] After the entire floating steering and anti-collision unit is installed and arranged, the buoyancy of the water keeps the entire floating steering and anti-collision unit in a constant position relative to the water surface; the bracket guide wheel group and the buoy guide wheel group are used to overcome the friction with the gate wall guide rail 29 to ensure smooth up and down movement;

[0076] Step 3, ship collision avoidance:

[0077] When a ship is sailing inside the lock chamber and is impacted by unstable water flow and collides with the lock wall, the ship will first collide with the rubber fender body 1. At this time, the rubber fender body 1 absorbs energy by rubber extrusion, cushions the impact force, reduces collision noise and vibration, and protects the navigation wall hydraulic structure and the ship itself from damage;

[0078] At the same time, the rubber fender body 1 will synchronously transmit the impact to the elastic buffer mechanism, which will be compressed to absorb the energy of the ship's collision or squeezing;

[0079] Step 4, recovery of ship position:

[0080] After the ship hits the rubber fender body 1, under the compression and buffering effect of the elastic buffer mechanism, the ship speed gradually drops to 0, and the elastic buffer mechanism slowly recovers, releasing energy, pushing the rubber fender body 1 outward, thereby applying force to the ship in a gentle manner, so that the ship diagonally crossing the pilot channel can be straightened;

[0081] Step 5: Replacement of the floating steering and anti-collision unit:

[0082] When the anti-collision device is damaged, the anti-collision device is lifted out as a whole through the lifting lugs installed on the buoy bracket body 12, replaced with spare parts, and then transported back to the yard for maintenance, so as to shorten the suspension maintenance time and reduce the impact on navigation.
