Description

Technical Field

[0001] The present invention belongs to the technical field of ship berthing protection, and particularly relates to a protection device for ship berthing. Background Art

[0002] After a ship sails a certain distance, it will berth in a port for the process of loading and unloading goods. However, the inertia of the ship's movement and the accuracy of control limit the ship, making it impossible to berth in the port by direct braking. Therefore, the ship mostly berths at the shore of the port by berthing, and generally uses two auxiliary tugboats to assist in adjusting the position of the ship to achieve ship berthing.

[0003] There is a prior art Chinese patent with the application number CN202121983739.0, which discloses a new type of outboard protection device, including a plurality of bottom stools detachably connected to the outside of the ship's hull and an anti-seismic component arranged on the bottom stools. The anti-seismic component includes a support longitudinal girder vertically fixed on the bottom stools and diffusion longitudinal girders arranged on both sides of the support longitudinal girder. A first movable girder and a second movable girder are respectively slidably connected to the ends of the support longitudinal girder and the diffusion longitudinal girders away from the ship's hull. First shock-absorbing springs connected to the second movable girders are arranged in the diffusion longitudinal girders. Bottom plates are fixedly connected to the ends of the first movable girder and the second movable girder away from the ship's hull, and a plurality of protective pads are detachably connected to the bottom plates.

[0004] Although the above technical solution reduces the cost of the device and buffers the impact force between ships to a certain extent during berthing. However, when the wind force in the port is relatively large, the ship will hit the shore of the dock under the influence of the wind force during the berthing process. Relying solely on the outboard protection device cannot buffer the impact force of the ship, and when there are other ships staying, it is impossible to control the ship from hitting other ships, which will cause greater harm and losses.

[0019] Technical effects and advantages of the present invention: A protective device for ship berthing proposed by the present invention has the following advantages compared with the prior art:

[0020] 1. By adding an anti-impact mechanism on the shore and installing and distributing a plurality of anti-impact mechanisms along the shore, the shore is covered with sufficient anti-impact mechanisms. When berthing, the hull contacts the anti-impact mechanism, reducing the damage to the hull caused by impacting the shore.

At the same time, it is not necessary to arrange too many rollers, saving resources.

[0022] 3. The buffer columns are successively placed into the feeding port of the feeding cylinder through the chain, and then are successively led out from the outlet of the feeding cylinder and fall on the water surface until all the buffer columns and the chain are tightened. The berthed ship will push the series of buffer columns to prevent the two ships from directly contacting, thereby achieving the isolation and protection effect on the two ships and improving the safety of the ship; and under the action of the chain, the series of buffer columns can ensure that the pulled buffer columns are always between the two ships, which is beneficial to the realization of the isolation and protection purpose between the two ships, and the buffer columns can also be conveniently retrieved through the chain.

[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides Figures 1-7 A protective device for ship berthing is shown.

[0032] Embodiment 1:

[0033] It comprises a base frame 1 installed on the shore, and an anti-impact mechanism 2 is installed on the base frame 1;

[0034] The anti-shock mechanism 2 includes a mounting frame 21, the mounting frame 21 is hinged on the base frame 1, a motor 22 is fixedly mounted on the base frame 1, the motor 22 is connected to the mounting frame 21 through a gear set, a rotating shaft is rotatably mounted between the mounting frame 21, a roller 23 is sleeved on the rotating shaft, and the roller 23 is formed by inflating a capsule;

[0035] A spacing adjustment mechanism 3 is connected between two adjacent chassis 1, and the spacing adjustment mechanism 3 includes a hydraulic telescopic rod 31, and the two ends of the hydraulic telescopic rod 31 are respectively detachably fixed to the two adjacent chassis 1, and a slideway 32 is fixed to the shore, and the chassis 1 is slidably installed on the slideway 32, and the chassis 1 at one edge is fixed to the shore. In order to solve the problem that when the wind force is strong in the port, the ship will hit the shore of the dock under the influence of the wind force during the berthing process, and the impact force of the ship cannot be buffered by the protective device installed outside the ship, and when there are other ships parked, it is impossible to control the collision with other ships, which will cause greater harm and losses, the present invention adds an anti-impact mechanism 2 to the shore, and installs and distributes multiple anti-impact mechanisms 2 along the shore, so that the shore is covered with enough anti-impact mechanisms 2, and the hull contacts the anti-impact mechanism 2 when berthing, reducing the damage to the hull caused by the impact on the shore, and using the anti-impact mechanism 2 in conjunction with the protective device installed outside the ship, a two-pronged approach is taken to achieve the purpose of improving the protective performance of the ship when berthing;

[0036] The specific working process is as follows: first, the base frame 1 is installed on the shore. When a ship is to dock, the control terminal of the present invention controls the motor 22 to drive the gear to rotate, and the gear set is meshed and transmitted to the hinge shaft of the mounting frame 21, so that the mounting frame 21 rotates with the gear set until the mounting frame 21 changes from a horizontal state of being attached to the shore to a horizontal state of extending out of the shore after rotating 180°. Therefore, the roller 23 rotatably installed on the mounting frame 21 extends out of the shore to buffer the impact of the docking ship, thereby protecting the shore and the hull structure; the state of the mounting frame 21 and the roller 23 is adjusted in time by the gear set transmission method. When there is no docking, they are in a retracted state. On the one hand, the space occupied by the anti-impact mechanism 2 is saved, and on the other hand, the maintenance and installation personnel can directly stand on the shore for installation and maintenance, which is very convenient; at the same time, the roller 23 is reduced from being damaged unnecessarily due to long-term protrusion from the shore, thereby improving the service life of the anti-impact mechanism 2;

[0037] When multiple ships need to berth, the berthed ships do not need rollers 23 for buffering after berthing, while the ships to be berthed need more rollers 23 for buffering. Therefore, the present invention provides a spacing adjustment mechanism 3, and uses a control terminal to control the corresponding hydraulic telescopic rod 31 in the spacing adjustment mechanism 3 to shrink the hydraulic telescopic rod 31, thereby pulling the rollers 23 in the berthed area to the berthed area, increasing the number of rollers 23 in the berthed area, and thus enhancing the protective effect during berthing; the present invention adjusts the position of the rollers 23 on the shore and the number of rollers 23 per unit distance through the shrinkage and extension of the hydraulic telescopic rod 31, thereby flexibly and centrally protecting the berthing area, enhancing the effective protection of ships, and at the same time, there is no need to arrange too many rollers 23, saving resources.

[0038] Further, a plurality of grooves 12 are provided on the outer edge of the roller 23. A driven column 13 is installed on the chassis 1. A plurality of leather strips 14 are installed on the outer circle of the driven column 13. The leather strips 14 are matched with the grooves 12. The driven column 13 is rotatably connected to the chassis 1 through a driven shaft; the diameter of the driven column 13 is smaller than that of the roller 23, and the height of the leather strip 14 is greater than the depth of the groove 12. When the ship impacts the surface of the roller 23, there is a certain angle between the outer circle of the roller 23 and the ship. Since the roller 23 rotates freely, the roller 23 will rotate by a certain angle after being stressed, thereby further releasing the impact force of the ship and enhancing the protection effect on the hull; since the height of the leather strip 14 is greater than the depth of the groove 12, when the leather strip 14 is matched with the groove 12, the leather strip 14 will be forcibly squeezed into the groove 12, thereby forming a squeezing effect on the contact part of the roller 23, causing elastic deformation and depression when the roller 23 contacts the driven column 13. The relative friction between the two generates a damping effect on the rotation of the roller 23. The impact force of the hull passes through the impact-elastic roller 23, breaking the relative friction between the roller 23 and the driven column 13, and the roller 23 rotates and is weakened multiple times, comprehensively enhancing the protection effect on the hull.

[0039] Embodiment 2:

[0040] A throwing mechanism 4 is further installed on the shore. The throwing mechanism 4 is used to throw buffer columns 44 between ships;

[0041] The throwing mechanism 4 includes an electric slide rail 41. The electric slide rail 41 is fixedly installed on the shore. A throwing frame 42 is installed on the electric slide rail 41. A throwing cylinder 43 is hingedly installed on the throwing frame 42. The throwing cylinder 43 is inclined, and a plurality of buffer columns 44 are placed in the throwing cylinder 43. The buffer columns 44 are connected to each other by a chain 45. One of the buffer columns 44 is fixed to the mounting frame 21 through the chain 45.

[0042] Further, an air pump 46 is installed on the throwing frame 42. The buffer column 44 is a rubber leather bag and is embedded with an air nozzle 47. The air pipe on the air pump 46 is inserted into the air nozzle 47 to inject air into the rubber leather bag. After the rubber leather bag is inflated and expanded, it forms a buffer column 44. A regular graphic structure 48 is provided on the outer circle of the buffer column 44.

[0043] Furthermore, a plurality of circumferentially distributed card slots 5 are provided on the side wall of the delivery rack 42, a limited slot 6 is provided on the hinge shaft of the delivery tube 43, a sleeve 7 is sleeved on the hinge shaft, a protrusion 8 is provided inside the sleeve 7 and is located in the limited slot 6, a card block 9 is provided outside the sleeve 7, and the card block 9 matches the card slot 5. When there are already ships docked in the port, the newly docked ship is prone to collide with the stopped ship, causing damage to the ship. Therefore, the present invention installs an anti-impact mechanism 2 on the shore to buffer the impact on the shore during berthing, and also uses the delivery mechanism 4 to buffer the delivery buffer column 44 between the two ships to prevent the two ships from being directly contacted and damaged.

[0044] Specifically, before berthing, the electric slide rail 41 is started by the control terminal, and the electric slide rail 41 drives the delivery frame 42 to move to the side of the parked ship. The staff then pulls the sleeve 7, so that the sleeve 7 extends under the sliding cooperation of the protrusion 8 and the limit groove 6, and the block 9 on the sleeve 7 is separated from the groove 5. At this time, the sleeve 7 and the hinge shaft can rotate freely. Since the hinge shaft is fixedly connected to the delivery tube 43, the angle of the delivery tube 43 can be adjusted, so that the outlet of the delivery tube 43 is lower than the delivery port, so that the delivery The barrel 43 faces the side of the parked ship. After the angle adjustment is completed, the staff presses the sleeve 7 to shrink the sleeve 7 back to the hinge shaft, and inserts the fixed block 9 into the corresponding slot 5 to restrict the sleeve 7, the hinge shaft and the delivery barrel 43 from rotating, thereby achieving the purpose of limiting. Through the protrusion 8 and the limiting slot 6 on the sleeve 7, the block 9 and the slot 5 cooperate to facilitate the angle adjustment and limiting of the delivery barrel 43. The inclined delivery barrel 43 can be delivered by the deadweight of the buffer column 44, which is convenient and quick.

[0045] Then the staff fixed one of the buffer columns 44 to the mounting frame 21 through the chain 45, and the other buffer columns 44 were connected in series through the chain 45 and then sequentially placed into the delivery port of the delivery tube 43, and then sequentially led out from the outlet of the delivery tube 43 and fell on the water surface until all the buffer columns 44 and the chain 45 were tightened. The berthed ship would push the buffer columns 44 connected in series to prevent the two ships from directly contacting each other, thereby achieving the isolation and protection effect of the two ships and improving the safety of the ships; and the buffer columns 44 connected in series, under the action of the chain 45, can ensure that the pulled buffer column 44 is always between the two ships, which is conducive to the realization of the isolation and protection purpose between the two ships, and the buffer columns 44 can also be conveniently retracted through the chain 45;

[0046] The air pump installed on the delivery rack 42 can supplement air to the buffer column 44 to be delivered as needed, ensuring that the buffer column 44 is in a full state during working hours, thus ensuring an effective isolation and protection effect. And a regular graphic structure 48 is provided on the outer circle of the buffer column 44, which can increase the surface area of the outer circle of the buffer column 44, making the surface of the buffer column 44 rougher, so that when the hull impacts the buffer column 44, it is not easy for the buffer column 44 to slide out and break away. Thus, the impact force of the hull acts on the elastic deformation of the buffer column 44, further ensuring the protection effect of the buffer column 44.

[0047] Embodiment 3:

[0048] A through groove 10 is left inside the buffer column 44, and a buffer assembly 11 is installed in the through groove 10; the buffer assembly 11 includes a large arc-shaped plate 111, and two hinge rods 112 are hinged on the concave surface of the large arc-shaped plate 111. The middle parts of the hinge rods 112 are both hinged with a support rod 113, and the other ends of the support rods 113 are jointly hinged on the concave surface of a small arc-shaped plate 114. The convex surfaces of the large arc-shaped plate 111 and the small arc-shaped plate 114 are both closely attached to the groove wall of the through groove 10; a number of fins 115 are arranged on the convex surfaces of the large arc-shaped plate 111 and the small arc-shaped plate 114, and the fins 115 are arranged in columns. The assembly process is as follows: the two ends of the support rod 113 are respectively hinged on the small arc-shaped plate 114 and the hinge rod 112, and then the common ends of the two hinge rods 112 are hinged on the large arc-shaped plate 111. Just installing the above-mentioned mechanism components can assemble the complete buffer assembly 11, which is convenient for modular production. Then, the buffer assembly 11 is stuffed into the through groove 10. At this time, the buffer column 44 is in a non-full state. After the buffer assembly 11 is stuffed well, the air pump is used to supplement air to the buffer column 44 to the optimal state. Since the buffer assembly 11 with a hinge structure can adapt to through grooves 10 with different diameters, the full buffer column 44 will press the convex surfaces of the large arc-shaped plate 111 and the small arc-shaped plate 114 and closely fit. The two ends of the hinge rod 112 also abut against the groove wall of the through groove 10 and even sink into the groove wall, and are wrapped by the elastically deformed groove wall, thus forming a buffer mechanism inside the buffer column 44. Once the impact column is impacted, both sides of the hinge rod 112 can also deflect and open along the hinge points on the large arc-shaped plate 111, thereby providing support for the buffer column 44 and further enhancing the buffering performance of the buffer column 44.
