Description

Technical Field

[0001] This utility model belongs to the field of wind turbine maintenance technology, specifically relating to a foldable wind turbine maintenance platform. Background Technology

[0002] Wind turbine generators are exposed to harsh environmental conditions such as strong gusts, turbulent winds, high temperatures, low temperatures, and large instantaneous impact loads for extended periods. In particular, the effects of natural conditions such as sandstorms, humidity in coastal areas, and smoke corrosion can easily lead to severe localized corrosion, paint peeling, or even complete detachment, thus affecting the service life of the wind turbine generators.

[0003] Currently, when maintaining wind turbines, external lifts or baskets are typically used. These require maintenance personnel to transport the lifts or baskets and install them before use. They cannot be integrated with the wind turbine tower, which greatly reduces maintenance efficiency. In addition, they occupy a lot of space and are greatly affected by environmental factors, thus having limitations. Therefore, we propose a foldable wind turbine maintenance platform. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model provides a technical solution: a foldable wind turbine maintenance platform, including a load-bearing platform 1 as the main load-bearing body, an installation port 6 in the middle of the load-bearing platform 1, the load-bearing platform 1 being fixedly installed on the outer surface of the wind turbine tower, and a first load-bearing grid 2, a second load-bearing grid 4, a third load-bearing grid 5 and a fourth load-bearing grid 7 being rotatably arranged on the four sides of the load-bearing platform 1 respectively. Specifically, the first load-bearing grid 2, the second load-bearing grid 4, the third load-bearing grid 5 and the fourth load-bearing grid 7 are all rotatably connected to the load-bearing platform 1 through a rotating shaft 21, which allows the first load-bearing grid 2, the second load-bearing grid 4, the third load-bearing grid 5 and the fourth load-bearing grid 7 to be unfolded and folded for storage;

[0026] Each of the first load-bearing space frame 2, the second load-bearing space frame 4, the third load-bearing space frame 5, and the fourth load-bearing space frame 7 has an expandable extension platform structure 3 on one side. The extension platform structure 3 includes a triangular connecting platform 32, which is hinged to the first load-bearing space frame 2, the second load-bearing space frame 4, the third load-bearing space frame 5, and the fourth load-bearing space frame 7 via a hinge 31. This allows the gaps between the first load-bearing space frame 2, the second load-bearing space frame 4, the third load-bearing space frame 5, and the fourth load-bearing space frame 7 to be filled, increasing the load-bearing area and facilitating the movement of maintenance personnel.

[0027] First, the support platform 1 is fixed to the wind turbine tower. During use, maintenance personnel rotate and unfold the first support frame 2, the second support frame 4, the third support frame 5, and the fourth support frame 7, so that the first support frame 2, the second support frame 4, the third support frame 5, and the fourth support frame 7 are arranged horizontally with the support platform 1. Then, the four sets of connecting platforms 32 are rotated and unfolded through the hinge 31. After unfolding, maintenance personnel can stand on the first support frame 2, the second support frame 4, the third support frame 5, the fourth support frame 7, and the connecting platforms 32 to carry out maintenance on the wind turbine tower. After maintenance is completed, the four sets of connecting platforms 32 are folded and stored first, and then the first support frame 2, the second support frame 4, the third support frame 5, and the fourth support frame 7 are folded and stored.

[0028] In this application, the first load-bearing space frame 2, the second load-bearing space frame 4, the third load-bearing space frame 5, and the fourth load-bearing space frame 7 are all made of steel, which ensures their load-bearing rigidity.

[0029] Furthermore, a limiting plate 9 is welded to the bottom of the bearing platform 1. The limiting plate 9 is used to position the first bearing space frame 2, the second bearing space frame 4, the third bearing space frame 5 and the fourth bearing space frame 7 after they are unfolded, so as to ensure that the first bearing space frame 2, the second bearing space frame 4, the third bearing space frame 5 and the fourth bearing space frame 7 remain horizontal with the bearing platform 1 after they are unfolded.

[0030] Furthermore, the bearing platform 1 is also welded with a fixing ear plate 8, which is provided with bolt mounting holes. By using fixing bolts, the bearing platform 1 can be fixed to the wind turbine tower.

[0031] Example 2

[0032] Please see Figure 5 as well as Figure 6 A connecting plate 33 is also welded and fixed on one side surface of the connecting platform 32. The connecting plate 33 is snapped into the connecting slot 34. The connecting slot 34 is set on one side surface of the first bearing space frame 2, the second bearing space frame 4, the third bearing space frame 5 and the fourth bearing space frame 7, which can provide auxiliary support for the connecting platform 32 and improve the bearing strength of the connecting platform 32 after it is unfolded.

[0033] When the first load-bearing space frame 2, the second load-bearing space frame 4, the third load-bearing space frame 5 and the fourth load-bearing space frame 7 rotate and unfold, the four sets of connecting platforms 32 are unfolded. After the connecting platforms 32 are unfolded, the connecting plates 33 can be inserted into the corresponding connecting slots 34. With the auxiliary support of the connecting plates 33, the load-bearing strength of the connecting platforms 32 is improved.

[0034] Furthermore, after the connecting platform 32 is folded up, its connecting plate 33 is stored in the positioning slot 35. The positioning slot 35 is set on one side surface of the bearing platform 1 to facilitate the storage of the connecting plate 33.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
