Description

Wharf anti-collision buffer protection device Technical Field

[0001] The present invention relates to the technical field of dock facilities, and in particular to a dock anti-collision buffer protection device. Background Art

[0002] A pier is a building on the seaside or riverside for passengers to get on and off, and for loading and unloading cargo. It is usually found in commercial cities with developed water and land transportation. Humans use piers as a place for ferries to dock and pick up passengers and cargo. Secondly, it may also be a landmark to attract tourists and for meetings. Common buildings or facilities around piers include cruise ships, ferries, container ships, warehouses, customs, pontoons, seagulls, fish markets, seaside promenades, stations, restaurants, or shopping malls. When ships dock at the pier, they often collide with the pier due to inertia. Long-term collisions can cause damage to the pier and the ship. To avoid this as much as possible, people usually tie some rubber tires to the side of the pier with ropes, using the elasticity of the rubber tires to absorb some of the impact force. However, this buffering method is relatively simple, and the rubber tires have limited energy absorption, resulting in poor buffering effect and inability to cope with collisions with larger impact forces.

[0028] As shown in Figures 1, 2, and 3, the present application provides a dock anti-collision buffer protection device, comprising:

[0029] The dock body 10 has a plurality of receiving slots 19 arranged side by side on its side;

[0030] There are multiple anti-collision buffer mechanisms, which are arranged corresponding to each receiving slot 19, and the anti-collision buffer mechanism includes:

[0031] A moving block 21 is movably inserted into the accommodating groove 19. A power conversion chamber 2 and a hydrodynamic chamber 7 located below and in communication with the power conversion chamber 2 are provided in the moving block 21. The bottom of the hydrodynamic chamber 7 is connected to the river and the sea through a water channel 20. A horizontal transmission screw 3 is rotatably provided in the power conversion chamber 2. A transmission sleeve 22 is movably screwed on the transmission screw 3 and a transmission gear 5 is fixedly provided. A first piston 6 is lifted and lowered in the hydrodynamic chamber 7.

[0032] The anti-collision member 24 is arranged on the side of the moving block 21 facing the river and the sea, and is detachably connected to the transmission sleeve 22 through multiple connecting rods 23 that are inserted into corresponding moving holes on the moving block 21 and are parallel to the transmission screw 3. The side of the anti-collision member 24 facing the river and the sea is detachably provided with multiple anti-collision rubber wheels 26.

[0033] The dock anti-collision buffer protection device provided by the present technical solution is mainly composed of a dock body 10 and a plurality of anti-collision buffer mechanisms for buffering the impact force of ships, wherein a plurality of receiving grooves 19 corresponding to the anti-collision buffer mechanisms are arranged side by side on the side of the dock body 10, and each anti-collision buffer mechanism includes a moving block 21 and an anti-collision member 24. The moving block 21 is movably inserted in the corresponding receiving groove 19. A power conversion chamber 2 and a hydrodynamic chamber 7 are arranged in the moving block 21. The hydrodynamic chamber 7 is located below the power conversion chamber 2 and is connected with it. The bottom of the hydrodynamic chamber 7 is connected with the river and the sea through a water transfer channel 20. The water in the river and the sea enters and exits the hydrodynamic chamber 7 through the water transfer channel 20. A horizontal transmission screw 3 is rotatably arranged in the power conversion chamber 2, and a transmission gear 5 coaxial with it is fixed on the transmission screw 3. A first piston 6 below the water surface is provided in the hydrodynamic chamber 7 for lifting and lowering, and a transmission gear 5 coaxial with it is vertically provided on the top of the first piston 6.

The rotation of the transmission screw 3 drives the transmission gear 5 to rotate, and then drives the transmission rack 4 and the first piston 6 to move up and down; the anti-collision part 24 is arranged on the side of the moving block 21 facing the river and the sea. The moving block 21 is provided with a plurality of moving holes connected to the power conversion chamber 2. A connecting rod 23 parallel to the transmission screw 3 is inserted into the moving hole. A transmission sleeve 22 is movable on the transmission screw 3.

The transmission sleeve 22 is detachably connected to one end of the connecting rod 23, and the other end of the connecting rod 23 is connected to the anti-collision part 24. The movement of the anti-collision part 24 drives multiple connecting rods 23 to move, and pushes the transmission sleeve 22 to move along the transmission screw 3 while driving the transmission screw 3 to rotate. The side of the anti-collision part 24 facing the river and the sea is detachably provided with a plurality of anti-collision rubber wheels 26 to provide a primary buffer for the impact force of the ship.

[0034] The working principle of the dock anti-collision buffer protection device of the present technical solution is as follows: the ship collides with the anti-collision rubber wheel 26 of the anti-collision member 24, performing a primary buffer, and then the anti-collision member 24 moves toward the dock body 10 under the pushing action of the ship, pushing the connecting rod 23 and the transmission sleeve 22 to move along the transmission screw 3. The movement of the transmission sleeve 22 causes the transmission screw 3 to rotate and the transmission gear 5 to rotate synchronously, thereby driving the transmission rack 4 and the first piston 6 to descend, and the first piston 6 pushes the water in the hydrodynamic chamber 7 along the water transfer channel 20 to flow into the river and the sea, while providing the ship with a thrust away from the dock body 10, thereby performing a secondary buffer for the impact of the ship; after the ship moves away from the dock body 10, the anti-collision member 24 is pushed in the direction away from the dock body 10, so that the anti-collision member 24 returns to its initial position before the initial ship collision, and at the same time, under the direct or indirect drive of the anti-collision member 24, the transmission sleeve 22, the transmission rack 4, and the first piston 6 return to their initial positions.

[0035] In this technical solution, a hydraulic telescopic rod or an electric telescopic rod can be set at the corresponding position of each anti-collision block on the side of the moving block 21 to push the anti-collision member 24 so that the anti-collision member 24 returns to its original position.

[0036] This technical solution includes at least the following beneficial effects: a plurality of accommodating grooves 19 are provided on the side of the dock body 10, a moving block 21 is provided in the accommodating groove 19, a connected power conversion chamber 2 and a hydrodynamic chamber 7 are provided in the moving block 21, a transmission screw 3 is rotatably provided in the power conversion chamber 2, a transmission sleeve 22 is movably screwed on the transmission screw 3 and a transmission gear 5 is fixedly provided, a first piston 6 is provided for lifting in the hydrodynamic chamber 7, a transmission rack 4 meshing with the transmission gear 5 is vertically provided on the top of the first piston 6, the bottom of the hydrodynamic chamber 7 is connected to the river and the sea through the water supply channel 20, the anti-collision member 24 located on the river and sea side of the dock body 10 is detachably connected to the transmission sleeve 22 through a plurality of movable connecting rods 23, and a plurality of anti-collision rubber wheels 26 are provided on the river and sea side of the anti-collision member 24, when a ship collides with the anti-collision member 24, the anti-collision rubber wheel 26 plays a primary buffering role on the impact force, and under the push of the ship The anti-collision part 24 moves, and then directly or indirectly drives the connecting rod 23 and the movable sleeve to move along the transmission screw 3, driving the transmission screw 3 and the transmission gear 5 to rotate synchronously, and then directly or indirectly drives the transmission rack 4 and the first piston 6 to move downward. The first piston 6 pushes the water in the hydrodynamic chamber 7 into the river and the sea through the water transfer channel 20, and provides the ship with a thrust in the direction back to the dock body 10, performing secondary buffering on the impact of the ship, that is, the present technical solution can perform multi-stage buffering on the impact impact of the ship, which can greatly improve the impact resistance of the device and effectively protect the dock body 10; the moving block 21 is movably inserted in the accommodating groove 19, which is convenient for the disassembly and assembly of the moving block 21; the anti-collision rubber wheel 26 is detachably connected to the anti-collision part 24, and the anti-collision part 24 is detachably connected to the transmission sleeve 22 through multiple connecting rods 23. The anti-collision rubber wheel 26 and the anti-collision part 24 are both wearing parts, which facilitates the disassembly and assembly of the two.

[0037] In another technical solution, as shown in Figures 1 and 2, in the dock anti-collision buffer protection device, the anti-collision member 24 is a U-shaped groove structure with a side opening. A plurality of vertical rotating shafts 25 are rotatably arranged between the top and bottom walls of the anti-collision member 24. A plurality of anti-collision rubber wheels 26 are rotatably sleeved on the rotating shafts 25. A plurality of pairs of horizontal movable grooves 29 are correspondingly arranged at the top and bottom of the anti-collision member 24. A connecting hole 30 is provided on the bottom wall of the movable groove 29. The two ends of the rotating shaft 25 respectively pass through their corresponding connecting holes 30 and are detachably connected to a limit block 31 slidably arranged in the movable groove 29. The limit block 31 is provided with a threaded hole, and the two ends of the rotating shaft 25 are inserted into the threaded hole and connected by a threaded structure. After the limit block 31 is removed and the rotating shaft 25 is pulled out from the connecting hole 30, the anti-collision rubber wheel 26 is left between the top and bottom walls of the anti-collision member 24, and the anti-collision rubber wheel 26 can be replaced.

[0038] In another technical solution, as shown in FIG2 , in the dock anti-collision buffer protection device, the connection hole 30 and the movable groove 29 are both rectangular, and a first buffer spring 32 is disposed within the movable groove 29 between the stop block 31 and the sidewall of the movable groove. When a vessel collides with the anti-collision rubber wheel 26, the rotating shaft 25 drives the stop block 31 to move along the movable groove 29, compressing the first buffer spring 32 and reducing the impact force.

[0039] In another technical solution, as shown in FIG1 , in the dock anti-collision buffer protection device, the water delivery channel 20 is tapered with a size gradually decreasing from the hydrodynamic chamber 7 to the river and sea direction, thereby increasing the impact force of the water flow on the ship.

A connecting block is disposed at one end of the second buffer spring 17, and a plurality of connecting grooves are disposed on the sidewall of the movable block 21. The connecting blocks are locked into their corresponding connecting grooves. The connecting blocks and connecting grooves can both be cylindrical and connected by a threaded structure. The other end of the second buffer spring 17 is free and can contact and abut against the sidewall of the receiving slot 19.

After the anti-collision member 24 moves to the moving block 21 and pushes the moving block 21 to move into the receiving groove 19, it pushes the second buffer spring 17 to compress it; the second buffer spring 17 pushes the second piston 14 to move in the air cavity 13, pushing the gas in the air cavity 13 to flow to the elastic airbag 16 through the air passage 15, causing the elastic airbag 16 to swell and buffer the impact force again.

[0043] In another technical solution, as shown in FIG1 , in the dock anti-collision buffer protection device, a baffle 12 with a vent hole is provided within the air cavity 13 between the second piston 14 and the connection point between the air channel 15 and the air cavity 13. The baffle 12 prevents the second piston 14 from excessive movement.

[0044] In another technical solution, as shown in FIG1 , in the dock anti-collision buffer protection device, the air channel 15 is located below the air cavity 13, and a horizontal slot is provided on the energy absorbing block 11 between the air cavity 13 and the air channel 15. A horizontal support plate 18 is provided below the second buffer spring 17 on the movable block 21, and the support plate 18 is movably inserted into the slot. The support plate 18 supports the second buffer spring 17 to prevent it from bending and sinking.

A horizontal locating plate 9 is provided at the bottom of the locating member 8, which is connected to the first openable cover 27 and the dock body 10 via a screw structure. The locating member 8 prevents the first openable cover 27 from being opened arbitrarily due to misoperation or strong winds. Opening the first openable cover 27 allows for maintenance operations on the components within the accommodating groove 19.

[0046] In another technical solution, as shown in FIG1 , in the dock anti-collision buffer protection device, a lifting ring 28 is provided at one end of the first openable cover 27 away from the hinge point between the first openable cover 27 and the dock body 10.
