Description

Technical Field

[0001] The utility model relates to the technical field of boarding devices, in particular to a boarding device for an offshore wind power platform. Background Art

[0002] In recent years, the offshore wind power industry has flourished both domestically and globally. Wind farms are experiencing increasing installed capacity, increasing numbers of turbines, and deepening water depths, posing increased risks and challenges to offshore wind farm operation and maintenance. Operation and maintenance vessels (O&M vessels) are vessels specifically designed for the operation and maintenance of offshore wind farms. They play a vital role in the construction, operation, and maintenance of offshore wind farms. Their primary missions include transporting personnel, equipment, and supplies, as well as providing emergency rescue services when necessary. Depending on their function and usage scenarios, O&M vessels can be categorized into various types, including standard O&M vessels, specialized catamaran O&M vessels, high-speed specialized catamaran O&M vessels, operation mother vessels, accommodation vessels, and jack-up O&M vessels. Standard O&M vessels are typically used for offshore wind farms, while specialized catamaran O&M vessels are suitable for operations in more distant waters and generally offer greater stability and seakeeping capabilities. High-speed specialized catamaran O&M vessels are designed for offshore wind farms at greater distances, offering higher speeds and enhanced wind and wave resistance. Operation and maintenance mother ships and living ships are mainly used to provide accommodation for operation and maintenance personnel and store spare parts, while self-elevating operation and maintenance ships are used to replace large components and perform maintenance work on wind turbines.

[0003] Currently, workers must ascend and descend ladders on offshore wind turbine towers to disembark from maintenance vessels (including offshore wind turbine platforms and offshore booster station platforms), as well as to return from platforms to the vessels. Due to the complex and volatile offshore environment, the vessel's own movement is significantly affected by waves. When approaching offshore wind turbine towers, the vessel sways violently, making it difficult for workers to access the platforms and posing a significant safety hazard. Furthermore, some ladders remain below sea level for extended periods, becoming severely corroded and infested with marine life, making them difficult for workers to climb and increasing safety risks. Therefore, mitigating risks and ensuring the safety of offshore workers has become an urgent issue. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0025] Example: Figures 1 to 5As shown, an offshore wind power platform boarding device mainly consists of a lifting platform 3 and a lifting mechanism. The lifting mechanism can drive the lifting platform 3 to rise and fall along the height direction of the offshore wind power tower 1, thereby changing the distance between the lifting platform 3 and the offshore wind power platform 2. When boarding the platform, the lifting platform 3 is pulled up to reduce the distance between the lifting platform 3 and the offshore wind power platform 2, thereby reducing the difficulty of boarding the platform; when leaving the platform, the lifting platform 3 is lowered to reduce the distance between the lifting platform 3 and the operation and maintenance ship, thereby reducing the difficulty of leaving the platform and ensuring safety during the boarding or leaving process. In order to ensure the stability of the lifting platform 3 during the lifting process and reduce the difficulty of operation, the lifting platform 3 is annular and is mounted on the outside of the offshore wind power tower 1. The annular design can also facilitate staff to approach the offshore wind power tower 1 from all directions and land on the lifting platform 3. In actual use, the lifting platform 3 is lowered to sea level via the lifting mechanism. Workers then maneuver the maintenance vessel to dock at the lifting platform 3. Because the lifting platform 3 has a larger surface area than a traditional ladder, workers can more easily and safely land on the lifting platform 3. The lifting mechanism then safely raises the lifting platform 3 to the bottom of the offshore wind turbine platform 2, allowing workers to safely land on the offshore wind turbine platform 2. To ensure the stability of the lifting mechanism, some components of the lifting mechanism are fixedly mounted on the offshore wind turbine platform 2. The lifting platform 3 is located below the offshore wind turbine platform 2. The offshore wind turbine platform 2 has a passage 17 connected to the lifting platform 3. This passage 17, as a stable and secure structure, ensures that personnel can safely move from the lifting platform 3 to the offshore wind turbine platform 2 even in adverse sea conditions. Multiple passages 17 are evenly spaced along the circumference of the offshore wind turbine platform 2, making various parts of the offshore wind turbine platform 2 more accessible and facilitating necessary inspections and maintenance.

[0026] In order to provide a stable power source and ensure the stability and reliability of the lifting operation, the lifting mechanism in this embodiment includes a winch 11 fixedly installed on the offshore wind power platform 2. There are at least two winches 11 and they are symmetrically distributed along the central axis of the offshore wind power platform 2. The winches 11 are all wound with steel wire ropes 12. The winches 11 are connected to the lifting platform 3 through the steel wire ropes 12, thereby realizing the lifting and lowering operation of the lifting platform 13. The symmetrical distribution of the winches 11 helps to achieve load balance when lifting heavy objects and avoid platform tilting or uneven structural stress caused by weight imbalance. Among them, the model of the winch 11 can be JM10T. After the winch 11 is connected to an external power supply, the output shaft of the winch 11 is rotated counterclockwise or clockwise to drive the lifting platform 3 to rise and fall.

[0027] In order to further ensure the stability of the lifting platform 3 during the lifting process and reduce the probability of the lifting platform tilting or shaking, an elastic abutment assembly is provided at the inner wall where the lifting platform 3 contacts the offshore wind turbine tower 1. The elastic abutment assembly is provided in multiple groups, and the multiple groups of the elastic abutment assembly are evenly distributed along the circumference of the lifting platform 3. Specifically, the elastic abutment assembly includes an abutment sleeve 13, an abutment slide rod 14, and an abutment elastic member 15. The abutment elastic member 15 is installed in the abutment sleeve 13 and is fixedly connected to one end of the abutment slide rod 14.

[0028] In order to facilitate movement and reduce the resistance of the lifting platform 3 during the lifting process, a roller 16 is provided at one end of the abutment slide rod 14 away from the abutment sleeve 13, and the roller 16 can roll up and down along the side wall of the offshore wind power tower 1.

[0029] To further reduce the difficulty of climbing onto the platform, a platform-shaped landing board 9 is provided on the top of the lifting platform 3. The landing board 9 has an entrance and exit 9-1 that is compatible with the shape and size of the passage 17. A ladder 10 is provided on the side wall of the lifting platform 3. The ladder 10 is arranged directly opposite the entrance and exit 9-1 and the passage 17, making it easy for workers to climb in and out.

[0030] To prevent workers from falling after landing on the lifting platform 3, guardrail assemblies are installed along the edge of the lifting platform 3. These guardrail assemblies are provided in multiple groups, evenly distributed along the circumference of the lifting platform 3, providing a certain degree of protection for workers landing on the lifting platform 3 from all angles. Each guardrail assembly includes two vertical guardrail sleeves 4 fixedly mounted on the lifting platform 3 at a distance. A first reinforcement rod 5 is installed horizontally between the two guardrail sleeves 4 to ensure the structural strength and performance of the guardrail assembly. After the staff enters the lifting platform 3, they release the guardrail, and the spring adaptively restores the height when it is not pressed down, so that the guardrail slide bar 6 is restored to its original position, so that the guardrail plays a protective role.

[0031] In this embodiment, an offshore wind power platform boarding device is provided. The boarding device has an ingenious structure. By providing a lifting platform 3 and a lifting mechanism, the lifting mechanism can drive the lifting platform 3 to rise and fall along the height direction of the offshore wind power tower 1, thereby reducing the distance between the lifting platform 3 and the offshore wind power platform 2 when boarding the offshore wind power platform; when leaving the offshore wind power platform 2, the distance between the lifting platform 3 and the operation and maintenance vessel is reduced, reducing the difficulty of boarding and leaving the platform, thereby ensuring safety during actual use, enhancing the user experience, and being conducive to the promotion and application of the above-mentioned offshore wind power platform boarding device in the market.
