Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower technology, specifically to a segmented wind turbine tower ring platform. Background Technology

[0002] As the global energy structure shifts towards cleaner and lower-carbon energy, wind power, as a core industry in the renewable energy sector, is showing a trend of continuously increasing single-unit capacity and tower height. As the core supporting component of wind turbine generators, the wind turbine tower requires an internal working platform for personnel inspection, equipment maintenance, and safety protection. Circular platforms have become the mainstream choice due to their perfect fit with the circular cross-section of the tower and their provision of a 360° working space without blind spots.

[0003] Traditional segmented wind turbine tower ring platforms have the following shortcomings: During the splicing process, the levelness and coaxiality of each unit must be ensured. The levelness error must be controlled within ≤3mm / m, and the coaxiality error within ≤2mm. Construction personnel must gradually fine-tune the unit height and angle using temporary support lugs on the inner wall of the tower (which need to be pre-welded and fixed, and the welding position accuracy must match the platform height). This requires multiple people to work together (usually 2-3 people simultaneously exerting force at different positions on the platform unit), and frequent verification of measurement data is necessary during adjustments. Even slight errors can render previous adjustments ineffective. Furthermore, different connection methods present additional challenges: if bolted connections are used, the bolt holes of adjacent units must be perfectly aligned (a hole deviation exceeding 0.3mm will prevent bolt insertion). Some misaligned holes caused by deviations require on-site enlargement, which is inconvenient. Therefore, improvements are needed. Utility Model Content

[0025] like Figures 1-7 As shown, this invention illustrates a segmented wind turbine tower annular platform according to one embodiment of the present invention. The platform includes multiple annular platforms 1. Assembly mechanisms 6 and installation mechanisms 7 are respectively provided on the bottom sides of the multiple annular platforms 1. The assembly mechanism 6 includes a first rectangular plate 61 welded to the bottom left side of the annular platform 1. The installation mechanism 7 includes a second rectangular plate 71 welded to the bottom right side of the annular platform 1. A rectangular groove 62 is formed on the outer side of the first rectangular plate 61. A rectangular block 63 is welded inside the rectangular groove 62. A movable groove 64 is formed inside the rectangular block 63. An inclined block 65 extending below the rectangular block 63 is slidably installed inside the movable groove 64. A telescopic spring 66 is elastically installed between the inner side of the inclined block 65 and the inner side of the movable groove 64. A slot 72 is formed on the inner side of the second rectangular plate 71, and a locking groove 73 is formed below the slot 72.

[0026] When multiple ring platforms 1 need to be spliced ​​to form a complete structure, the assembly mechanism 6 and the installation mechanism 7 on both sides of the bottom of the ring platform 1 cooperate with each other. In the assembly mechanism 6, a rectangular block 63 is provided inside the rectangular groove 62 on the outer side of the first rectangular plate 61. The rectangular block 63 is aligned with the slot 72 on the inner side of the second rectangular plate 71 in the installation mechanism 7 and inserted. During the insertion process, the inner wall of the slot 72 squeezes the inclined block 65 in the movable groove 64 inside the rectangular block 63, causing the inclined block 65 to slide along the movable groove 64 and compress the telescopic spring 66. When the rectangular block 63 is fully inserted into the slot 72, the telescopic spring 66 releases its elastic force to push the inclined block 65 back to its original position. The lower end of the inclined block 65 is locked into the slot 73 below the slot 72, realizing the connection and fixation of adjacent ring platforms 1, thereby completing the splicing and assembly of multiple ring platforms 1.

[0027] By setting assembly mechanisms 6 and installation mechanisms 7 on the bottom sides of multiple annular platforms 1 respectively, the assembly mechanism 6 has a rectangular groove 62 on the outer side of the first rectangular plate 61 and a rectangular block 63 welded thereon. The rectangular block 63 has a movable groove 64 and a slidably installed inclined block 65 extending below. A telescopic spring 66 is elastically installed between the inclined block 65 and the movable groove 64. The installation mechanism 7 has a slot 72 on the inner side of the second rectangular plate 71 and a locking groove 73 below. At the same time, with the sliding cooperation of the limiting grooves 67 on both sides of the movable groove 64 and the upper limit block 68 of the inclined block 65, the rapid and accurate splicing of adjacent annular platforms 1 is achieved. Simply insert the rectangular block 63 into the slot 72, and the inclined block 65 will automatically lock into the locking groove 73 under the action of the telescopic spring 66 after being squeezed. There is no need for complicated on-site adjustment tools and operations, which solves the technical problems of repeated position adjustment, reliance on professional high-precision tools and low splicing efficiency in the splicing of segmented platforms in the prior art.

[0028] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower ring platform. Weighing mechanisms 2 are provided at the bottom of both ends of the ring platform 1. The weighing mechanism 2 includes a first connecting member 21 welded to the bottom of the ring platform 1. A bearing member 22 is welded to the inner wall of the wind turbine tower. The first connecting member 21 and the bearing member 22 are connected by a second connecting member 23.

[0029] In some examples, when the annular platform 1 needs to be fixed to the inner wall of the wind turbine tower, the weighing mechanisms 2 at the bottom of both ends of the annular platform 1 come into play. The first connecting member 21 of the weighing mechanism 2 is connected to the annular platform 1, and the load-bearing member 22 of the inner wall of the wind turbine tower serves as the supporting foundation. The first connecting member 21 and the load-bearing member 22 are connected together by the second connecting member 23 passing through the adaptation structure between the first connecting member 21 and the load-bearing member 22. This allows the annular platform 1 to be stably fixed to the inner wall of the tower by the weighing mechanism 2. At the same time, the weighing mechanism 2 can sense the load-bearing status of the annular platform 1 in real time, ensuring that the annular platform 1 can be used safely within the load-bearing range.

[0030] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower ring platform. A limit ring 3 is welded to the upper part of the inner end of the ring platform 1, and a guardrail 4 is bolted to the upper part of the ring platform 1. The bottom bolt of the guardrail 4 is connected to the front side of the limit ring 3.

[0031] In some examples, the limiting ring 3 and the shielding protection of the opening 5 work together to ensure the safe use of the space above the annular platform 1.

[0032] like Figures 1-7As shown, on the other hand, this utility model also provides a segmented wind turbine tower ring platform, wherein the surface of the ring platform 1 is provided with an opening 5, which is used for staff to move up and down using the elevator inside the wind turbine tower.

[0033] In some examples, when staff need to move up and down inside the wind turbine tower, they can do so using an opening 5 on the surface of one of the annular platforms 1. After the elevator reaches a position near the annular platform 1, staff can move between the elevator and the annular platform 1 through the opening 5. The opening 5 is positioned to match the elevator entrance and exit, ensuring a smooth transfer process and meeting the staff's need for passage between the annular platform 1 and the elevator at different heights.

[0034] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower annular platform, with limiting grooves 67 opened on both sides of the movable groove 64, and limiting blocks 68 that are slidably connected inside the limiting grooves 67 are welded to both sides of the upper end of the inclined block 65.

[0035] In some examples, when the inclined block 65 in the movable groove 64 inside the rectangular block 63 slides along the movable groove 64, the limiting blocks 68 on both sides of the upper end of the inclined block 65 simultaneously slide inside the limiting grooves 67 on both sides of the movable groove 64. The limiting grooves 67 constrain the sliding trajectory of the limiting blocks 68, preventing the inclined block 65 from deviating or tilting during the sliding process, ensuring that the inclined block 65 always slides along the preset direction of the movable groove 64, ensuring the precise engagement of the inclined block 65 with the slot 73, and improving the stability of the connection between the assembly mechanism 6 and the installation mechanism 7.

[0036] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower annular platform, wherein the length of the limiting block 68 is adapted to the length of the limiting groove 67, and the width of the limiting block 68 is clearance-fitted with the width of the limiting block 68.

[0037] In some examples, the inclined block 65 slides along the movable groove 64, causing the limiting blocks 68 on both sides of the upper end of the inclined block 65 to slide inside the limiting grooves 67 on both sides of the movable groove 64. Because the length of the limiting block 68 is adapted to the length of the limiting groove 67, the limiting block 68 can slide to the maximum stroke in the limiting groove 67 without disengaging from the limiting groove 67. At the same time, the width of the limiting block 68 and the width of the limiting groove 67 are matched with a gap, which not only prevents the inclined block 65 from shaking due to excessive gap between the limiting block 68 and the limiting groove 67, but also prevents the limiting block 68 from sliding due to insufficient gap, ensuring that the sliding process of the inclined block 65 is stable and smooth.

[0038] like Figures 1-7As shown, on the other hand, this utility model also provides a segmented wind turbine tower ring platform, with the outer side of the rectangular block 63 wrapped with a wear-resistant coating made of tungsten carbide, and the size of the rectangular block 63 and the size of the slot 72 are fitted together with a clearance.

[0039] In some examples, when the assembly mechanism 6 and the installation mechanism 7 work together to assemble the ring platform 1, the rectangular block 63 is inserted into the slot 72 and contacts the inner wall of the slot 72. The wear-resistant coating on the outside of the rectangular block 63 can reduce the wear of the rectangular block 63 and the slot 72 during insertion, removal and long-term use, thus extending the service life of the rectangular block 63 and the slot 72. At the same time, the size of the rectangular block 63 and the size of the slot 72 are matched with the clearance, which ensures that the rectangular block 63 can be smoothly inserted into the slot 72, while avoiding excessive clearance that would cause the ring platform 1 to wobble after assembly, thus ensuring the stability of the assembly structure.

[0040] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower annular platform, where the natural length of the telescopic spring 66 is adapted to the depth of the movable groove 64, and when the telescopic spring 66 is in its natural state, the lower end of the inclined block 65 extends to below the rectangular block 63.

[0041] In some examples, when the rectangular block 63 is not inserted into the slot 72, the telescopic spring 66 is in its natural state. Because the natural length of the telescopic spring 66 matches the depth of the movable slot 64, the telescopic spring 66 provides support to the inclined block 65, causing the lower end of the inclined block 65 to extend below the rectangular block 63, preparing for the inclined block 65 to engage with the slot 73 after the rectangular block 63 is inserted into the slot 72. When the rectangular block 63 is inserted into the slot 72 and presses against the inclined block 65, the telescopic spring 66 is compressed and stores elastic force. After the rectangular block 63 is fully inserted into the slot 72, the telescopic spring 66 releases the elastic force to push the inclined block 65 back to its original position, ensuring that the inclined block 65 can smoothly engage with the slot 73, thus achieving a reliable connection between the assembly mechanism 6 and the installation mechanism 7.

[0042] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower annular platform. The limiting ring 3 is distributed in a ring along the inner edge of the annular platform 1, and the axis of the limiting ring 3 is collinear with the axis of the annular platform 1. The guardrail 4 is set along the upper surface edge of the annular platform 1. The inner side of the guardrail 4 is in contact with the outer side of the limiting ring 3. The bolt connection points between the bottom of the guardrail 4 and the front side of the limiting ring 3 are evenly distributed along the circumference of the limiting ring 3.

[0043] In some examples, the limiting rings 3 are distributed in a ring along the inner edge of the ring platform 1 and their axes are collinear with the axis of the ring platform 1, so that the limiting effect of the limiting rings 3 on the upper part of the ring platform 1 is evenly distributed, avoiding local weak limiting. The guardrails 4 are set along the edge of the upper surface of the ring platform 1 and their inner side is attached to the outer side of the limiting rings 3. The bolt connection points between the bottom of the guardrails 4 and the front side of the limiting rings 3 are evenly distributed along the circumference of the limiting rings 3, so that the connection force between the guardrails 4 and the limiting rings 3 is evenly transmitted. The limiting rings 3 provide stable support for the guardrails 4. With the cooperation of the limiting rings 3, the guardrails 4 form a protective structure around the upper part of the ring platform 1, which fully protects the safety of use in the area above the ring platform 1.

[0044] like Figures 1-7 As shown, on the other hand, this utility model also provides a segmented wind turbine tower annular platform, with the opening 5 located in the central region of the surface of the annular platform 1, and the center of the opening 5 and the center of the annular platform 1 being on the same vertical line.

[0045] In some examples, opening 5 is located in the central area of ​​the surface of the annular platform 1, with its center aligned vertically with the center of the annular platform 1, placing opening 5 in the center of the annular platform 1. When the elevator approaches the annular platform 1, the elevator entrance and exit correspond to the position of opening 5. After exiting the elevator, staff can directly enter the central area of ​​the annular platform 1 through opening 5 and then move around the annular platform 1, avoiding the need for staff to detour when moving due to the offset position of opening 5, thus improving the convenience of staff movement.

[0046] Working principle and usage process of this utility model: Multiple components, including the annular platform 1, weighing mechanism 2, limit ring 3, guardrail 4, opening 5, assembly mechanism 6, and installation mechanism 7, were transported to the wind turbine tower installation site in advance. The quantity of each component was counted, and any damage or deformation was checked. Special attention was paid to verifying the sliding performance of the rectangular block 63 and inclined block 65 in the assembly mechanism 6, as well as the elasticity of the telescopic spring 66. The dimensions of the slot 72 and groove 73 in the installation mechanism 7 were checked to ensure they met assembly requirements. Impurities and dust were cleaned from the inner wall of the wind turbine tower. The load-bearing components 22 of the weighing mechanism 2 were welded to predetermined positions on the inner wall of the tower, ensuring that the welding positions of the load-bearing components 22 were horizontal and secure, and that multiple load-bearing components 22 were on the same circumferential surface, providing a stable support foundation for the subsequent installation of the annular platform 1. Simultaneously, inspect the inner wall of the tower for defects such as protrusions or dents that may affect platform installation. If any are found, grind and repair them. For each annular platform 1, first weld the first connecting piece 21 of the weighing mechanism 2 to the bottom of both ends of the annular platform 1, ensuring that there are no incomplete welds or leaks at the weld between the first connecting piece 21 and the annular platform 1, and that the position of the first connecting piece 21 corresponds to the position of the bearing piece 22 on the inner wall of the tower. Weld the limiting ring 3 above the inner end of the annular platform 1, ensuring the perpendicularity of the limiting ring 3 to the annular platform 1 during welding to prevent the limiting ring 3 from tilting. A bolted connection method is used. The guardrail 4 is installed above the annular platform 1. When tightening the bolts, the specified torque must be used to prevent the guardrail 4 from loosening. Using hoisting equipment, the first annular platform 1 is hoisted to a designated height inside the tower, aligning the first connecting piece 21 at the bottom of the annular platform 1 with the supporting member 22 on the inner wall of the tower. The first connecting piece 21 and the supporting member 22 are then connected via the second connecting piece 23, initially fixing the position of the first annular platform 1. The second annular platform 1 is hoisted to the side of the first annular platform 1, aligning the installation mechanism 7 on the right side of the second annular platform 1 with the assembly mechanism 6 on the left side of the first annular platform 1. The second annular platform 1 is pushed, aligning the rectangular groove 62 on the outer side of the first rectangular plate 61 in the assembly mechanism 6 with the second rectangular plate 71 in the installation mechanism 7, causing the rectangular block 63 to insert into the slot 72 inside the second rectangular plate 71. During the insertion of the rectangular block 63 into the slot 72, the inclined block 65 in the movable groove 64 inside the rectangular block 63 is pressed by the inner wall of the slot 72, sliding upwards along the movable groove 64, while simultaneously compressing the telescopic spring 66. After the rectangular block 63 is fully inserted into the slot 72, the inclined block 65 slides down under the elastic action of the telescopic spring 66 and gets into the slot 73 below the slot 72, thus achieving the initial splicing of the adjacent annular platforms 1.During this process, it is necessary to observe the sliding of the limiting block 68 in the limiting groove 67 of the assembly mechanism 6 to ensure that the limiting block 68 slides synchronously with the inclined block 65 and to prevent the inclined block 65 from shifting. Repeat the above operation to hoist the remaining annular platforms 1 in sequence. Through the cooperation of the assembly mechanism 6 and the installation mechanism 7, all annular platforms 1 are spliced ​​to form a complete annular platform structure. After all annular platforms 1 are spliced, check the connection between the first connecting piece 21 at the bottom of each annular platform 1 and the supporting piece 22 on the inner wall of the tower. Further tighten the connection with the second connecting piece 23 to ensure that each annular platform 1 is stably fixed inside the tower. At the same time, check the connection status between the assembly mechanism 6 and the installation mechanism 7 between adjacent annular platforms 1. If there is a situation where the inclined block 65 is not fully inserted into the slot 73, the position of the annular platform 1 needs to be adjusted to ensure reliable connection.
