[0002] The offshore wind turbine operation and maintenance platform utilizes advanced technologies such as information technology, the Internet of Things, big data, and cloud computing to achieve real-time monitoring, data analysis, fault diagnosis, and predictive maintenance of offshore wind farm equipment. This platform helps wind farms achieve remote centralized monitoring and unmanned on-site management, reducing operation and maintenance costs and improving the overall operational efficiency and safety of the wind farm.

[0003] Due to the limited space on offshore wind turbine maintenance platforms, components requiring repair are not easily placed on the maintenance platform.

[0004] An existing publicly available technical solution, CN208151997U, discloses an environmentally friendly operation and maintenance platform for offshore wind turbines, comprising a platform body and multiple side plates. The platform body includes shelves, studs, filters, and sealing gaskets. Three or more shelves are stacked and fixed to each other by the studs. Filters and sealing gaskets are provided between adjacent shelves. The filters are located inside the space enclosed by the sealing gaskets on the same layer. By hinged one end of a side plate to the edge of the uppermost shelf, when large components need to be repaired, the side plate can be rotated to be flush with the upper surface of the operation and maintenance platform, increasing the space of the operation and maintenance platform.

[0005] In actual implementation, the side plate is rotated upwards until it is perpendicular to the upper surface of the platform body, and then fixed to the platform body by bolts and other fasteners to expand the space of the maintenance platform. However, the side plate has a weak supporting effect and lacks bottom support, making it inconvenient to use when repairing heavier components. Summary of the Invention

[0006] The purpose of this utility model is to provide an environmentally friendly operation and maintenance platform for offshore wind turbines, which can support the extension plate from the bottom through support components, thereby improving the stability of the extension plate and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly operation and maintenance platform for offshore wind turbines, comprising a platform body, a working compartment at the top of the platform body, a support component at the bottom of the platform body, and an extension component around the platform body, the extension component including an extension plate;

[0008] The support assembly includes a guide base, inside which a transmission screw is installed. A push-out block is mounted on the surface of the transmission screw via a screw nut. A transmission worm gear is positioned above the push-out block, and a transmission worm is mounted on one side of the transmission worm gear. One end of the transmission worm is fixedly connected to a servo motor, which is installed inside the working chamber. The inner wall of the guide base has several oblique movable holes, and a support rod passes through the movable holes. A support plate is fixedly mounted on the top of the support rod, and an arc-shaped head is fixedly mounted on the bottom of the support rod.

[0009] Preferably, a support spring is provided on one side of the arc-shaped head, and a movable ring is connected to the end of the support spring.

[0010] Preferably, the movable ring and the support spring are both sleeved on the outside of the support rod, and the movable ring is movably connected to the support rod, with the movable ring abutting against the inner wall of the guide base.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An environmentally friendly operation and maintenance platform for offshore wind turbines includes a platform body 1, a working cabin 2 on the top of the platform body 1, a support component 4 at the bottom of the platform body 1, and an extension component 3 around the platform body 1, wherein the extension component 3 includes an extension plate 301.

[0028] The support assembly 4 includes a guide base 401, inside which a transmission screw 408 is installed, and an ejector block 405 is installed on the surface of the transmission screw 408 via a screw nut. A transmission worm gear 407 is provided above the ejector block 405, and a transmission worm 406 is installed on one side of the transmission worm gear 407. One end of the transmission worm 406 is fixedly connected to a servo motor, which is installed inside the working chamber 2. The inner wall of the guide base 401 has several oblique movable holes 404, and a support rod 402 passes through the movable holes 404. A support plate 403 is fixedly provided on the top of the support rod 402, and an arc-shaped head 409 is fixedly provided on the bottom of the support rod 402.

[0029] By adopting the above technical solution, when it is necessary to support the expansion plate 301, the servo motor is started. The power output end of the servo motor drives the transmission worm gear 406 to rotate. Then, the transmission worm gear 406 drives the transmission worm wheel 407 to rotate, and the transmission worm wheel 407 drives the transmission screw 408 to rotate synchronously. As the transmission screw 408 rotates, the push block 405 moves downward. Since the push block 405 has an inverted frustum structure, the bottom diameter of the push block 405 is much smaller than the top diameter of the push block 405. As the push block 405 moves, the arc head 409 can be pushed outward. The arc head 409 pushes the support rod 402 to move inside the movable hole 404. As the arc head 409 is pushed outward, the arc head 409 gradually moves away from the vertical center line of the guide base 401, thereby causing the support plate 403 to move towards the expansion plate 301 until the support plate 403 abuts against the bottom of the expansion plate 301, thus supporting the expansion plate 301.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, a support spring 410 is provided on one side of the arc-shaped head 409, and a movable ring 411 is connected to the end of the support spring 410. Both the movable ring 411 and the support spring 410 are sleeved on the outside of the support rod 402, and the movable ring 411 is movably connected to the support rod 402. The movable ring 411 abuts against the inner wall of the guide base 401. The guide base 401 is elastically connected to the arc-shaped head 409 through the movable ring 411 and the support spring 410. The push block 405 moves up and down inside the guide base 401 through the transmission screw 408, and a guide rod is provided on one side of the transmission screw 408 that passes through the inside of the push block 405. The support rod 402 is correspondingly provided with the extension plate 301, and the extension plate 301 is movably connected to the support plate 403. The top surface of the support plate 403 is parallel to the horizontal plane.

[0031] The extension component 3 also includes a connector 302 fixed to one side of the extension plate 301. The connector 302 has a fixing screw 303 connected to its internal thread. The four corners of the platform body 1 are fixedly installed with fixing piles 5 for supporting the platform body 1.

[0032] By adopting the above technical solution, as the arc-shaped head 409 moves, the support spring 410 is squeezed inward, and the distance between the arc-shaped head 409 and the movable ring 411 is reduced. When it is not necessary to support the extension plate 301, the push block 405 moves upward. After the arc-shaped head 409 loses its force, the support rod 402 can be reset under the action of the support spring 410, and the support plate 403 can be moved away from the extension plate 301. The extension plate 301 can be separated from the platform body 1 by fixing screws 303.

[0033] Working principle: When support is needed for the expansion plate 301, the servo motor is started. The power output of the servo motor drives the transmission worm gear 406 to rotate. The transmission worm gear 406 drives the transmission screw 408 to rotate synchronously through the transmission worm wheel 407, causing the push block 405 to move downward and push the arc head 409 outward. The arc head 409 pushes the support rod 402 to move inside the movable hole 404. As the arc head 409 is pushed outward, it gradually moves away from the vertical center line of the guide base 401, and the support spring 4... When the 10 is pressed inward, the distance between the arc-shaped head 409 and the movable ring 411 is reduced, thereby causing the support plate 403 to move closer to the extension plate 301 until the support plate 403 abuts against the bottom of the extension plate 301, supporting the extension plate 301. Conversely, when the transmission worm gear 406 rotates in the opposite direction, the push block 405 moves upward, and after the arc-shaped head 409 loses its force, the support rod 402 can be reset under the action of the support spring 410, causing the support plate 403 to move away from the extension plate 301.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
