Description

Technical Field

[0001] This invention relates to wind turbine transportation and installation technology, and more particularly to an offshore wind turbine transportation and installation platform. Background Technology

[0002] The biggest difference between offshore wind turbine construction and onshore wind power lies in their location. Because offshore wind turbine foundations are located at sea, they incur additional loads and uncertainties, leading to more complex designs and diverse structural forms depending on sea conditions. For rock-based seabed offshore wind turbines, the two most common types of fixed foundations are rock-embedded monopiles and gravity foundations. Gravity foundations require large "centipede trucks" for transport within the prefabrication yard, as well as large floating cranes and other equipment.

[0003] The installation of offshore wind power equipment includes the installation of the wind turbine casing, which consists of a seabed section and an offshore section. The seabed section needs to be fixed to the seabed, and then multiple casings are gradually stacked and connected before the wind turbine is finally erected. The wind turbine requires the cooperation of transport and lifting vessels to lift the casing using hoisting equipment. Accurate positioning is crucial during casing installation, and the challenges of wave and weather conditions can increase the difficulty of hoisting and positioning. Therefore, a convenient installation platform for transporting offshore wind turbine casings is provided. Summary of the Invention

The wind turbine body is inserted and installed through the insertion hole. The arc-shaped groove and the insertion hole are kept in communication and the center lines of the arc-shaped groove and the insertion hole are perpendicular to each other. The support base has a limiting component, which is used to limit the wind turbine body in case of accidental disengagement. A driving component is disposed on one side of the support base, and a pushing component is provided on the driving component; A rotating component is hinged to the pusher component. The rotating component has a protrusion and a support opening. The support opening is located at the lower end of the protrusion. The rotating component is driven to rotate by the wind turbine cylinder. A buffer member is hinged to a rotating component, with one end of the buffer member hinged to the rotating component and the other end placed inside the support base, allowing the buffer member to slide inside the support base; A carrier member hinged to a buffer member, one end of which is placed inside a support opening, and the other end is hinged to the buffer member via a hinge block.

[0006] In this invention, the support base is composed of a support plate, a first side plate and a second side plate. The arc-shaped groove and the insertion hole are provided on the support plate.

[0007] In this invention, the insertion hole is provided with a blocking surface and a first guiding slope, and the blocking surface and the first guiding slope are arranged opposite to each other.

[0008] In this invention, the rotating member is provided with symmetrically arranged first hinge portions, and a hinge area is formed between the first hinge portions. The pushing member is arranged in the hinge area through a first hinge rod and is hinged to the first hinge portion through the first hinge rod. The lower end of the support plate is provided with guide portions on both sides, and a first strip hole is provided in the middle of the guide portion. The first hinge rod is located in the first hinge hole.

[0009] In this invention, the protrusion is provided with a second guide slope, the support opening is provided with a sliding slope, and the lower end of the rotating member is provided with a guide slope.

[0010] In this invention, the bearing member is composed of a plate and symmetrically arranged second hinge parts, with a clearance area formed between the symmetrically arranged second hinge parts. The second hinge parts are hinged to the hinge block by a second hinge rod. The second hinge parts are arranged at one end of the plate, and a buffer arc segment that cooperates with the support opening is provided on the other side of the plate. A buffer gap is formed between the buffer arc segment and the plate.

[0011] In this invention, the second hinge rod is provided with a reset member, which consists of a blocking part and symmetrically arranged spiral parts and support rods. The blocking part is in contact with the buffer, the spiral part is sleeved on the second hinge rod, and the support rod is located at the lower end of the bearing member.

[0012] In this invention, the buffer consists of a pressure plate, a reinforcing plate, and symmetrically arranged connecting arms and hinge arms.

One end of the support block is hinged to the middle of the sliding seat via a fifth hinge rod, and the other end is hinged to the first cylinder via a sixth hinge rod. The second cylinder is used to push the sliding seat to move on the support seat.

[0015] The offshore wind turbine cylinder transportation and installation platform of this invention has the following beneficial effects: The platform is equipped with movable rotating components, buffer components, and load-bearing components. The load-bearing components achieve closure, separating the seawater from the transport vessel's deck and preventing accidents. The installation of offshore wind power equipment includes the installation of wind turbine cylinders. During installation, the movable rotating components limit the movement of cylinders of different diameters, preventing incorrect cylinder hoisting and subsequent errors. This can be achieved by changing the distance between the rotating components and the blocking surface to allow different cylinders to pass through, enhancing the stability of the overall stacking installation process and effectively reducing accidents caused by incorrect cylinder installation.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1 to 18As shown, this offshore wind turbine casing transportation and installation platform of the present invention includes a lifting vessel 1, a transport vessel 2, and an installation platform 3 mounted on the transport vessel 2. The installation platform 3 can hold... The lifting vessel 1 is equipped with a lifting device 4, which is used to lift the wind turbine casing 5. The wind turbine casing 5 can be equipped with multiple lifting lugs 6, which are used to cooperate with the lifting device 4 to lift the wind turbine casing 5 from a horizontal state to a vertical state, so that the wind turbine casing 5 can be vertically inserted into the insertion hole 7 of the installation platform 3.

[0020] The transport vessel 2 works in conjunction with the hoisting vessel 1. The hoisting equipment 4 on the hoisting vessel 1 is used to hoist and install the wind turbine cylinder 5 on the transport vessel 2. The transport vessel 2 is equipped with an installation platform 3 for positioning and installing the wind turbine cylinder 5.

[0021] During the installation of offshore wind power equipment, the seabed portion of the wind turbine casing 5 is installed first. This seabed portion needs to be fixed to the seabed, and then multiple wind turbine casings 5 ​​are gradually stacked and connected before finally erecting the wind turbine. The offshore wind power equipment requires the cooperation of the transport vessel 2 and the crane vessel 1 to lift the wind turbine casing 5 using the lifting equipment 4. The wind turbine casing 5 must be positioned accurately during installation.

[0022] The installation platform 3 includes a support base 8, a limiting component 9, a driving component 10, a rotating component 11, a buffer component 12, and a bearing component 13. The rotating component 11 is hinged to the lower end of the support base 8, the buffer component 12 is hinged to the rotating component 11, and the bearing component 13 is hinged to the buffer component 12. When the diameter of the wind turbine casing 5 to be installed is greater than the distance between the rotating component 11 and the blocking surface 33, the wind turbine casing 5 to be installed can push the second guide slope 35 on the rotating component 11, keeping the rotating component 11 rotating around the first hinge rod 15. When the diameter of the wind turbine casing 5 to be installed is smaller than the distance between the rotating part 11 and the blocking surface 33, the wind turbine casing 5 cannot be placed on the second guide slope 35. As a result, the lower end of the wind turbine casing 5 to be installed will not push the rotating part 11. When the rotating part 11 is not rotating, its bearing part 13 is in the support port 16 of the rotating part 11. Therefore, the wind turbine casing 5 inserted into the insertion hole 7 will be blocked by the bearing part 13, preventing it from moving further down. This effectively avoids incorrect docking and installation of the wind turbine casing 5.

[0023] The support base 8 is provided with an arc-shaped groove 17 and an insertion hole 7. The wind turbine casing 5 is inserted and installed through the insertion hole 7. The arc-shaped groove 17 and the insertion hole 7 are kept in communication, and their center lines are perpendicular. During transportation, the wind turbine casing 5 is placed horizontally in the arc-shaped groove 17 and then fixed to the support base 8 by anchor cables, achieving horizontal positioning of the wind turbine casing 5 and facilitating transportation. The anchor cable structure can adopt existing technology, so it will not be described in detail here.

[0024] The support base 8 is equipped with a limiting component 9, which is used to limit the wind turbine casing 5 in case of accidental disengagement. When the wind turbine casing 5 is being hoisted and inserted into the insertion hole 7, it may fall due to accidental operation. The limiting component 9 can support and limit the lifting lug 6.

[0025] The limiting assembly 9 comprises a first cylinder 18, a second cylinder 19, a sliding seat 20, and a support block 21. The first cylinder 18 pushes the support block 21, and the second cylinder 19 pushes the sliding seat 20. The sliding seat 20 is mounted on the support base 8 via a slide rail 22. One end of the support block 21 is hinged to the middle of the sliding seat 20 via a fifth hinge rod 23, and the other end is hinged to the first cylinder 18 via a sixth hinge rod 24. The second cylinder 19 pushes the sliding seat 20 to move on the support base 8.

[0026] The sliding seat 20 has a rotating area 25 for accommodating the support block 21. The support block 21 has a push arm 26 and a support surface 27. The support surface 27 supports the wind turbine casing 5, while the push arm 26 has a notch 28. The first cylinder 18 extends into the notch 28 and is hinged to it via a sixth hinge rod 24. When the support block 21 needs to support the wind turbine casing 5, the sliding seat 20 can be pushed by the second cylinder 19, while the first cylinder 18 pulls the push arm 26, causing the support block 21 to rotate and keeping the support surface 27 facing upwards. When the support block 21 is not needed, the sliding seat 20 can be pulled by the second cylinder 19. When the lifting lug 6 of the wind turbine casing 5 reaches the position of the support block 21, the first cylinder 18 can push the push arm 26, keeping the support block 21 rotating, thereby causing the support surface 27 to rotate into the rotating area 25 without limiting the position of the wind turbine casing 5.

[0027] The support base 8 is composed of a support plate 29, a first side plate 30, and a second side plate 31. An arc-shaped groove 17 and an insertion hole 7 are provided on the support plate 29. A driving component 10 is provided on the first side plate 30. A sliding plate 32 is provided on the second side plate 31 and is located at the lower end of the support plate 29.

[0028] The insertion hole 7 is provided with a blocking surface 33 and a first guide slope 14, which are arranged opposite to each other. The first guide slope 14 is used to guide the wind turbine cylinder 5 to be installed and inserted, so that it moves closer to the blocking surface 33.

[0029] The driving component 10 is located on one side of the support base 8. The driving component 10 is a cylinder. The driving component 10 is provided with a pusher 36. The pusher 36 is used to push the rotating component 11, so that the rotating component 11 slides on the guide part 43 through the first hinge rod 15, thereby changing the distance between the rotating component 11 and the blocking surface 33.

[0030] The rotating member 11 is hinged to the pushing member 36. The rotating member 11 is provided with a protrusion 38 and a support port 16. The protrusion 38 is used to cooperate with the wind turbine cylinder 5 so that it can push the rotating member 11 and keep the rotating member 11 rotating around the first hinge rod 15, and make the bearing member 13 disengage from the support port 16, thereby making the bearing member 13 rotate and keeping the reset member 63 deformed under force.

[0031] The protrusion 38 is provided with a second guide slope 35, the support opening 16 is provided with a sliding slope 39, and the lower end of the rotating part 11 is provided with a guide slope 40.

[0032] The support opening 16 is located at the lower end of the protrusion 38. The rotating component 11 is driven to rotate by the wind turbine cylinder 5, causing it to separate from the bearing component 13, facilitating the downward movement of the wind turbine cylinder 5 into the seabed. The rotating component 11 is provided with symmetrically arranged first hinge portions 41, forming a hinge area 42 between the first hinge portions 41. The pushing component 36 is disposed within the hinge area 42 via a first hinge rod 15, and is hinged to the first hinge portion 41 via the first hinge rod 15. The lower end of the support plate 29 is provided with guide portions 43 on both sides, and a first strip hole 44 is provided in the middle of the guide portion 43. The first hinge rod 15 is located within the first strip hole 44, guiding the position of the first hinge rod 15 through the first strip hole 44, allowing it to move closer to or away from the blocking surface 33, suitable for limiting or allowing passage of wind turbine cylinders 5 of different diameters.

[0033] Of course, to prevent the first hinge rod 15 from rotating within the first slot 44 when pushed by the driven member 10, sliding blocks can be set at both ends of the first hinge rod 15 to keep the first hinge rod 15 from rotating, and keep the rotating member 11 rotating around the first hinge rod 15.

[0034] The buffer 12 is hinged to the rotating member 11. One end of the buffer 12 is hinged to the rotating member 11, and the other end is placed inside the support base 8, allowing the buffer 12 to slide inside the support base 8. The buffer 12 consists of a pressure plate 45, a reinforcing plate 46, and symmetrically arranged connecting arms 47 and hinge arms 48. An opening region 49 is formed between the connecting arms 47, and a through region 50 is formed between the hinge arms 48. A pushing protrusion 37 is provided at the connection between the hinge arms 48 and the connecting arms 47.

[0035] The articulated arm 48 is provided with a third hinge portion 51, which is hinged to the rotating member 11 via a third hinge rod 52. The pressure plate 45 is provided with a fourth hinge portion 53, which is hinged to the hinge block 54 via a fourth hinge rod 55. The hinge block 54 realizes the hinged connection between the buffer member 12 and the bearing member 13, and when the bearing member 13 is under force, the external force can be transmitted to the spring 56 on the buffer member 12 through the hinge block 54.

[0036] A symmetrically arranged positioning rod 57 is provided at the lower end of the pressure plate 45. A spring 56 is sleeved on the positioning rod 57. A second strip-shaped hole 58 that cooperates with the positioning rod 57 is provided on the sliding plate 32. The spring 56 is located on the sliding plate 32, and the blocking part 59 is in contact with the positioning rod 57. The positioning rod 57 can keep the buffer 12 sliding on the sliding plate 32, so that the buffer 12 can move along with the rotating part 11. When the bearing member 13 is subjected to a wind turbine cylinder 5 with a small diameter placed directly on the bearing member 13, the bearing member 13 can pull down the buffer 12, and the external force is applied to the spring 56.

[0037] The support member 13 is hinged to the buffer member 12. One end of the support member 13 is placed inside the support opening 16, and the other end is hinged to the buffer member 12 through the hinge block 54. The support member 13 consists of a plate 60 and symmetrically arranged second hinge parts 61. A clearance area 62 is formed between the symmetrically arranged second hinge parts 61. The clearance area 62 is used to avoid the reset member 63, so that it can be extended to the lower end of the support member 13 of the buffer member 12 through the support rod 64.

[0038] The second hinge part 61 and the hinge block 54 are hinged together by the second hinge rod 65. The second hinge part 61 is located at one end of the plate 60, and the other side of the plate 60 is provided with a buffer arc segment 66 that cooperates with the support port 16. A buffer gap 34 is formed between the buffer arc segment 66 and the plate 60. When the smaller diameter wind turbine cylinder 5 is placed on the support member 13, the buffer arc segment 66 and the spring 56 provide double buffering.

[0039] A reset member 63 is provided on the second hinge rod 65. The reset member 63 is used to push the carrier member 13 to rotate and reset into the support opening 16. The reset member 63 consists of a blocking part 59, a symmetrically arranged spiral part 67, and a support rod 64. The blocking part 59 contacts the buffer part 12, the spiral part 67 is sleeved on the second hinge rod 65, and the support rod 64 is located at the lower end of the carrier member 13. When the wind turbine casing 5 pushes the rotating part 11, the rotating part 11 no longer restricts the position of the carrier member 13, allowing the carrier member 13 to rotate around the second hinge rod 65, keeping the carrier member 13 open, and the wind turbine casing 5 falls.

[0040] After the wind turbine casing 5 is installed, the rotating part 11 is reset first. As the bearing part 13 is pushed by the reset part 63, it is kept in place and pushed to reset. In this way, the guide slope 40 pushes the lower end of the rotating part 11 toward the driving part 10. The buffer part 12, which is hinged to the rotating part 11, will be moved toward the driving part 10. Since the buffer part 12 and the bearing part 13 are hinged, they will not affect each other. The bearing part 13 is pushed by the reset part 63 and passes over the guide slope 40 to re-enter the support opening 16.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
