Description

Technical Field

[0001] This invention relates to the field of semi-submersible vessel float-over technology, and more particularly to a float-over guiding and buffering device for semi-submersible vessels. Background Technology

[0002] The semi-submersible vessel float-over guiding and buffering device is a specialized marine engineering equipment auxiliary system that integrates guidance, limiting and buffering functions. It is installed on the deck of the semi-submersible vessel or in the float-over operation area. Its core function is to prevent collisions between the vessel and the semi-submersible vessel or the working structure during the entire process of vessel entry, float-over docking and withdrawal, and to ensure the accuracy, safety and stability of the float-over docking.

[0003] A search revealed that Chinese Patent CN220391487U discloses a guide device for floating over a large platform semi-submersible vessel, comprising: a box-shaped main structure; an I-beam steel structure fixedly connected to one side of the box-shaped main structure; a reinforcing pad fixedly connected to the section of the I-beam steel structure away from the box-shaped main structure; the side of the reinforcing pad away from the I-beam steel structure fixedly connected to the semi-submersible vessel; a lateral side reinforcing plate fixedly connected to the end of the box-shaped main structure near the semi-submersible vessel; the lateral side reinforcing plate being adapted to and fixedly connected to the shape of the semi-submersible vessel's bottom; and several horizontal main ribs fixedly connected to the side of the lateral side reinforcing plate away from the box-shaped main structure; the horizontal main ribs being adapted to and fixedly connected to the shape of the semi-submersible vessel's bottom. This device can assist the semi-submersible vessel in smoothly entering the relatively narrow guide frame slot during floating over operations. However, in practical use, this solution still has the following shortcomings: During the ship-entry phase of a semi-submersible vessel's float-over operation, the vessel needs to be towed by tugboats to move and position itself towards the float-over area. However, existing ship-entry guidance devices generally adopt a fixed installation method. The arrangement angles of their guide frames and limiting structures, as well as their effective guidance range, are designed for a single preset ship-entry direction, lacking directional adaptability. When the vessel enters from other directions, the fixed guidance device cannot form an effective guidance path. This not only leads to an increase in the vessel's lateral offset and deviation of the ship-entry trajectory from the safety envelope, increasing the difficulty of tugboat operation and operation time, but also limits the flexibility of semi-submersible vessel float-over operations because the guidance components cannot accurately match the vessel's entry attitude. It cannot adapt to the actual operational needs of multi-directional ship entry, seriously affecting the efficiency and safety of the float-over operation.

[0004] Therefore, it is necessary to design an inboard guiding buffer device for semi-submersible vessel floating to solve the above problems. Summary of the Invention

[0009] As a preferred embodiment of the present invention, both the inner wall of the support plate and the outer wall of the adjustment plate are provided with anti-slip textures.

[0010] As a preferred embodiment of the present invention, the control structure includes a support plate slidably mounted on the inner wall of the guide shell, a support ring fixedly mounted at the end of the support plate, a dual-head servo motor fixedly mounted on the inner wall of the support ring, an electric push rod fixedly mounted on the inner bottom surface of the guide shell, the telescopic end of the electric push rod fixedly mounted on the bottom surface of the support plate, two through holes opened on the top surface of the guide shell, and two lifting plates corresponding to the positions of the through holes symmetrically fixedly mounted on the top surface of the support ring.

[0011] As a preferred embodiment of the present invention, the top surface of the lifting plate is provided with a plurality of evenly distributed mounting ball grooves, and a supporting ball is rotatably mounted on the inner wall of the mounting ball groove.

[0012] As a preferred embodiment of the present invention, the guide assembly includes a sliding shell slidably mounted on the inner wall of the slot. A top plate is rotatably mounted on the inner wall of the sliding shell via a rotating shaft. An elastic support bladder is provided between the bottom surface of the top plate and the top surface of the sliding shell. A connecting plate is fixedly mounted at the end of the top plate. An opening is provided on the inner side of the ship entry guide plate. A pull rope is provided on the inner side of the opening, and one end of the pull rope is fixedly connected to the connecting plate. Two fixing plates are symmetrically fixedly mounted at the end of the sliding shell. A spring is fixedly mounted between the fixing plate and the inner wall of the slot.

[0013] As a preferred embodiment of the present invention, the top surface of the sliding shell and the retracted state of the top plate are flush with the top surface of the ship entry guide plate.

[0014] As a preferred embodiment of the present invention, the buffer assembly includes a mounting base fixedly installed on the buffer end of the hydraulic damping rod, a shaft is rotatably mounted on the inner wall of the mounting base, a buffer plate is fixedly fitted on the outer wall of the shaft, a buffer seat is fixedly installed on the end of the buffer plate away from the mounting base, and the end of the pull rope away from the connecting plate is fixedly connected to the end of the buffer plate.

[0015] As a preferred embodiment of the present invention, the buffer seat is made of elastic and wear-resistant rubber material, and a limiting rod corresponding to the buffer plate is fixedly installed on the inner wall of the mounting seat.

[0016] The present invention has the following beneficial effects: 1. In this invention, the direction of the ship entry guide plate can be adjusted by a dual-head servo motor and an electric push rod. During adjustment, the electric push rod is lifted to make the connecting spline fit into the spline groove, driving the adjustment plate to rotate the ship entry guide plate. The two ship entry guide plates always remain parallel and accurately correspond to the ship entry direction. After adjustment, the electric push rod retracts, and the adjustment plate is fixed under the action of gravity and anti-slip texture to avoid deviation. This design can adapt to different ship entry angles without moving the entire ship, greatly improving the adaptability to complex loading scenarios. 2. In this invention, the guide shell can slide along guide groove one and two. During adjustment, the dual-head servo motor switches to drive the drive wheel. First, the guide shell of guide groove two is moved to guide groove one. Then, the positions of the two guide shells are adjusted synchronously to match the ship entry point. After a single ship is loaded, the ship submerges to separate the guide plate from the ship. The guide shell can then be quickly moved to another loading position. After the ship floats up, the operation is repeated. There is no need to frequently adjust the ship's anchoring position, which shortens the loading interval and improves the efficiency of continuous loading of multiple ships. 3. In this invention, the ship entry guide plate is equipped with a protective structure consisting of a hydraulic damping rod and a buffer plate. When the ship contacts the ship entry guide plate, it presses down on the top plate and pulls the buffer plate to a vertical position through the pull rope. When the ship impacts, the hydraulic damping rod buffers the impact force. At the same time, when the hydraulic damping rod extends and retracts, the pull rope drives the sliding shell to slide along the slot, avoiding structural interference that affects the damping effect, absorbing the collision energy when the ship enters the ship, preventing damage to the ship and semi-submersible ship structure, and reducing safety risks during loading.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-4 A semi-submersible vessel hull guide buffer device for floating, comprising a semi-submersible vessel hull 11, a guide groove 12 formed on the float of the semi-submersible vessel hull 11, a guide groove 2 13 formed on the float of the semi-submersible vessel hull 11 perpendicular to and communicating with the guide groove 12, a guide shell 14 slidably installed on the inner wall of the guide groove 12 and the guide groove 2 13, a boat entry guide plate 15 provided on the top surface of the guide shell 14, a drive structure provided on the inner bottom of the guide shell 14, a slot 61 formed at one end of the boat entry guide plate 15, and a hydraulic damping rod 51 fixedly installed at the end of the boat entry guide plate 15 away from the slot 61. The drive structure includes a drive wheel 21 rotatably mounted at the center of the bottom surface of the guide housing 14. The guide housing 14 has mounting openings 22 on both adjacent sides. Two adjusting wheels 23 corresponding to the positions of the mounting openings 22 are rotatably mounted on the bottom surface of the guide housing 14, and the outer wall of the drive wheel 21 is in contact with the outer wall of the two adjusting wheels 23.

[0021] In use, the staff first need to drive the semi-submersible vessel hull 11 to the location where the vessel is loaded. The staff can then operate the two guide shells 14 on the float of the semi-submersible vessel hull 11. When the drive wheel 21 rotates, it can drive the adjusting wheel 23 to rotate. The outer wall of the adjusting wheel 23 passes through the mounting port 22 and fits against the inner wall of the first guide groove 12 and the second guide groove 13. Then, when the adjusting wheel 23 rotates, it can drive the guide shell 14 to slide along the first guide groove 12 and the second guide groove 13. First, the guide shell 14 in the second guide groove 13 is driven into the first guide groove 12. Then, the two guide shells 14 can be driven simultaneously to adjust their positions in the first guide groove 12 so as to correspond to the vessel loading position.

[0022] Reference Figure 3-6The inner side of the guide shell 14 is provided with an adjustment assembly for adjusting the direction of the ship entry guide plate 15. The adjustment assembly includes a support plate 31 fixedly installed on the top surface of the guide shell 14. An adjustment plate 32 is provided on the inner wall of the support plate 31. Both the inner wall of the support plate 31 and the outer wall of the adjustment plate 32 are provided with anti-slip textures. The ship entry guide plate 15 is fixedly installed on the top surface of the adjustment plate 32. A dual-head servo motor 34 is provided on the inner side of the guide shell 14. The top output end of the dual-head servo motor 34 passes through the top surface of the guide shell 14 and is located inside the support plate 31. A connector 33 is fixedly installed on the inner top surface of the adjustment plate 32. Spline grooves 36 are opened on the bottom surface of the connector 33 and the top surface of the drive wheel 21. Connecting splines 35 corresponding to the spline grooves 36 are fixedly installed on both sides of the output end of the dual-head servo motor 34. A control structure adapted to the dual-head servo motor 34 is provided on the inner side of the guide shell 14. The control structure includes a support plate 41 slidably mounted on the inner wall of the guide shell 14, a support ring 42 fixedly mounted at the end of the support plate 41, and a dual-head servo motor 34 fixedly mounted on the inner wall of the support ring 42. An electric push rod 43 is fixedly mounted on the inner bottom surface of the guide shell 14, and the telescopic end of the electric push rod 43 is fixedly mounted on the bottom surface of the support plate 41. Two through holes 44 are opened on the top surface of the guide shell 14. Two lifting plates 45 corresponding to the positions of the through holes 44 are symmetrically fixedly mounted on the top surface of the support ring 42. Several evenly distributed mounting ball grooves 46 are opened on the top surface of the lifting plates 45, and a support ball 47 is rotatably mounted on the inner wall of the mounting ball grooves 46.

[0023] The electric push rod 43 controls the position adjustment of the dual-head servo motor 34. The electric push rod 43 extends, causing the support plate 41, support ring 42, and dual-head servo motor 34 to move upwards. When the dual-head servo motor 34 moves upwards, the connecting spline 35 on its upper output end can be inserted into the spline groove 36 on the bottom surface of the connector 33 on the top surface of the adjusting plate 32. The lifting plate 45 on the top surface of the support ring 42 can pass through the through-hole 44 on the top surface of the guide shell 14. When the connecting spline 35 is fully inserted into the spline groove 36, the electric push rod 43 continues to extend. The support ball 47 in the ball groove 46 at the top of the lifting plate 45 contacts the top surface of the adjusting plate 32 and pushes the adjusting plate 32 upwards. The adjusting plate 32 can then separate from the support plate 31, and the dual-head servo motor 34 can be started to drive the adjusting plate 32 through the connecting spline 35 and spline groove 36. The guide plate 15 is rotated to change the direction of the ship entry guide plate 15. In the initial state, the two ship entry guide plates 15 are placed parallel to the hull of the semi-submersible vessel 11. After the two ship entry guide plates 15 are adjusted, they can correspond to the ship entry direction, and the two are always in a parallel state. After the ship entry guide plates 15 are adjusted, the electric push rod 43 can be shortened, and the support ball 47 can be separated from the adjustment plate 32. Under the action of gravity, the adjustment plate 32 can be inserted into the support plate 31, and under the action of the anti-slip texture, the adjustment plate 32 and the ship entry guide plate 15 can maintain the ship entry direction. Then the electric push rod 43 is shortened, and the connecting spline 35 on the bottom output end of the dual-head servo motor 34 can be inserted into the spline groove 36 on the top surface of the drive wheel 21. After the connecting spline 35 is fully inserted into the spline groove 36, the dual-head servo motor 34 can be started to drive the drive wheel 21 to rotate.

[0024] Reference Figure 2 and Figure 8 The inner wall of the slot 61 is provided with a guide assembly, which includes a sliding shell 62 slidably installed on the inner wall of the slot 61. A top plate 63 is rotatably installed on the inner wall of the sliding shell 62 via a rotating shaft. An elastic support bladder 64 is provided between the bottom surface of the top plate 63 and the top surface of the sliding shell 62. The top surface of the sliding shell 62 and the top plate 63 are flush with the top surface of the ship entry guide plate 15 when they are in the retracted state. A connecting plate 65 is fixedly installed at the end of the top plate 63. An opening 66 is opened on the inner side of the ship entry guide plate 15. A pull rope 67 is provided on the inner side of the opening 66, and one end of the pull rope 67 is fixedly connected to the connecting plate 65. Two fixing plates 68 are symmetrically fixedly installed at the end of the sliding shell 62. A spring 69 is fixedly installed between the fixing plate 68 and the inner wall of the slot 61.

[0025] Reference Figure 2 and Figure 7The buffer end of the hydraulic damping rod 51 is provided with a buffer assembly. The buffer assembly includes a mounting base 52 fixedly installed on the buffer end of the hydraulic damping rod 51. A shaft 53 is rotatably installed on the inner wall of the mounting base 52. A buffer plate 54 is fixedly fitted on the outer wall of the shaft 53. A buffer seat 55 is fixedly installed on the end of the buffer plate 54 away from the mounting base 52. The end of the pull rope 67 away from the connecting plate 65 is fixedly connected to the end of the buffer plate 54. The buffer seat 55 is made of elastic wear-resistant rubber material. A limit rod 56 corresponding to the buffer plate 54 is fixedly installed on the inner wall of the mounting base 52.

[0026] After adjusting the two guide plates 15, the semi-submersible hull 11 can be submerged. Once submerged to the predetermined depth, the vessel to be loaded is towed by a tugboat into the buoyancy shield above the semi-submersible hull 11. During the submersion process, the vessel can be positioned between the two guide plates 15 and move along the guide plates 15. When the vessel contacts the guide plates 15, it can press against the top plate 63, causing the top plate 63 to rotate into the sliding housing 62. During the rotation of the top plate 63, the buffer plate 54 in the mounting base 52 can be pulled by the pull rope 67. When the buffer plate 54 is pulled, it can rotate via the shaft 53 and, under the action of the limit rod 56, can rotate to a vertical position. The vessel moves along the guide plates... After the plate 15 enters the float, it can contact and impact the buffer seats 55 on the two ship entry guide plates 15. During the impact, the hydraulic damping rod 51 can buffer the impact force. When the hydraulic damping rod 51 buffers the extension and retraction, the top plate 63 and the sliding shell 62 can be pulled by the pull rope 67. The sliding shell 62 can slide along the slot 61 to avoid affecting the damping effect of the hydraulic damping rod 51. As the entry of a single ship is completed, the semi-submersible hull 11 can continue to submerge until the ship entry guide plate 15 is separated from the loaded ship. Then, the guide shell 14 is moved to another ship entry position, and the semi-submersible hull 11 is normally floated to the loading position. The above steps can be repeated to guide and load the ship.

[0027] The specific working principle of this invention is as follows: In use, the operator first needs to drive the semi-submersible hull 11 to the loading location. The operator can then manipulate the two guide shells 14 on the hull 11's float, controlling the position of the dual-head servo motor 34 via an electric push rod 43. The electric push rod 43 extends, causing the support plate 41, support ring 42, and dual-head servo motor 34 to move upwards. When the dual-head servo motor 34 moves upwards, the connecting spline 35 on its upper output end can be inserted into the spline groove 36 on the bottom surface of the connector 33 on the top surface of the adjusting plate 32. Furthermore, the lifting plate 45 on the top surface of the support ring 42 can pass through the through-hole 44 on the top surface of the guide shell 14. When key 35 is fully inserted into spline groove 36, electric push rod 43 continues to extend. The support ball 47 in ball groove 46 at the top of lifting plate 45 can contact the inner top surface of adjustment plate 32 and push adjustment plate 32 upward. Adjustment plate 32 can be separated from support plate 31. Then, dual-head servo motor 34 can be started to drive adjustment plate 32 and ship entry guide plate 15 to rotate through spline 35 and spline groove 36, so as to change the direction of ship entry guide plate 15. In the initial state, the two ship entry guide plates 15 are placed parallel to the hull of semi-submersible vessel 11. After the direction of the two ship entry guide plates 15 is adjusted, they can correspond to the ship entry direction, and the two are always in a parallel state. After adjusting the inlet guide plate 15, the electric push rod 43 can be shortened, and the support ball 47 can be separated from the adjustment plate 32. Under the action of gravity, the adjustment plate 32 can be inserted into the support plate 31, and under the action of the anti-slip texture, the adjustment plate 32 and the inlet guide plate 15 can maintain the inlet direction. Then, the electric push rod 43 is shortened, and the connecting spline 35 on the bottom output end of the dual-head servo motor 34 can be inserted into the spline groove 36 on the top surface of the drive wheel 21. After the connecting spline 35 is fully inserted into the spline groove 36, the dual-head servo motor can be started. Servo motor 34 drives drive wheel 21 to rotate. When drive wheel 21 rotates, it can drive adjustment wheel 23 to rotate. The outer wall of adjustment wheel 23 passes through mounting port 22 and fits against the inner wall of guide groove 12 and guide groove 23. When adjustment wheel 23 rotates, it can drive guide shell 14 to slide along guide groove 12 and guide groove 23. First, guide shell 14 in guide groove 213 is driven into guide groove 12. Then, the two guide shells 14 can be driven synchronously to adjust their positions in guide groove 12 so as to correspond to the ship entry position. After adjusting the two guide plates 15, the semi-submersible vessel hull 11 can be submerged. Once it reaches the predetermined depth, the vessel to be loaded is towed by a tugboat into the buoyancy shield above the semi-submersible vessel hull 11. During the submersion process, the vessel can be positioned between the two guide plates 15 and move along the direction of the guide plates 15. When the vessel contacts the guide plates 15, it can press against the top plate 63, causing the top plate 63 to rotate into the sliding housing 62. During the rotation of the top plate 63, the buffer plate 54 in the mounting base 52 can be adjusted via the pull rope 67. When the buffer plate 54 is pulled, it can rotate through the shaft 53 and rotate to a vertical state under the action of the limit rod 56. After the ship enters the floating platform along the ship entry guide plate 15, it can contact and impact the buffer seats 55 on the two ship entry guide plates 15. During the impact, the hydraulic damping rod 51 can buffer the impact force. When the hydraulic damping rod 51 buffers the extension and retraction, the top plate 63 and the sliding shell 62 can be pulled by the pull rope 67. The sliding shell 62 can slide along the slot 61 to avoid affecting the damping effect of the hydraulic damping rod 51. Once a single vessel has entered the vessel, the semi-submersible hull 11 can continue to submerge until the entry guide plate 15 separates from the loaded vessel. Then, the guide shell 14 is moved to another entry position, and the semi-submersible hull 11 is raised to the loading position normally. The above steps can then be repeated to guide and load the vessel.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
