[0027] To facilitate understanding of the tower door provided in this application embodiment, its application scenario is first described. The tower door provided in this application embodiment is applied to the tower of a wind turbine. Currently, in use, the door frame and door panel of the tower door are connected by hinges, with exposed bolts, making them easily disassembled and posing a low level of security. Furthermore, the tower door is not secured after opening, easily creating safety hazards. Therefore, this application embodiment provides a tower door to improve its safety. A detailed description follows with reference to specific drawings and embodiments.

[0028] Please refer to the above. Figure 1 and Figure 2 , Figure 1 A schematic diagram of the tower door structure is shown. Figure 2 An exploded view of the tower door is shown. The tower door provided in this embodiment mainly includes a door frame 10 and a door panel 20. The door frame 10 is fixed to the tower, and the door panel 20 is rotatably engaged with the door frame 10. The tower door provided in this embodiment is an inward-pushing door, meaning that when the tower door is opened, the door panel 20 rotates into the space inside the tower. The various components of the tower door are described in detail below with reference to the specific accompanying drawings.

[0029] Continue to refer to Figure 1 and Figure 2 The door frame 10 provided in this embodiment is a frame structure that can be fixed to the tower by welding. The door frame 10 has a hollow area to accommodate the door panel 20. When the tower door is closed, the door panel 20 blocks the hollow area of ​​the door frame 10; when the tower door is open, the door panel 20 rotates relative to the door frame 10, and the hollow area of ​​the door frame 10 becomes the passage for workers to enter and exit the tower.

[0030] When the door frame 10 and the door panel 20 are rotatably connected, a pivot 40 is fixed on the door frame 10, and a pivot sleeve 60 is provided on the corresponding door panel 20. The pivot sleeve 60 is fitted onto the pivot 40 and can rotate relative to it, thereby realizing the rotatable connection between the door frame 10 and the door panel 20. Specifically, the pivot 40 is located on the side of the door frame 10 facing the interior space of the tower, and the pivot 40 is not exposed in the hollow area of ​​the door frame 10. That is, when the door frame 10 is fixed to the tower, the pivot 40 is obscured by the door frame 10 when viewed from the outside of the tower towards the inside. Similarly, when the pivot sleeve 60 is provided, it extends beyond the edge of the door panel 20 to mate with the pivot 40 on the door frame 10. When the door frame 10 and the door panel 20 are connected in this way, the door frame 10 can block the rotating connection between the door panel 20 and the door frame 10 when the tower door is closed, so that the door panel 20 cannot be removed from the outside, thus improving the safety of the tower door during use.

[0031] Also, please refer to Figure 4 , Figure 4 It shows Figure 2 A partially enlarged schematic diagram at point B. The tower door also includes a locking assembly 80, which can be used to lock the door panel 20. Specifically, the locking assembly 80 is used to lock the door panel 20 to the door frame 10 when the door panel 20 is pushed into the tower cavity to a set position. That is, when the tower door is open, the opened tower door can be locked and fixed, improving the safety of the tower door during use.

[0032] As can be seen from the above description, the tower door provided in this embodiment achieves a rotatable connection between the door panel 20 and the door frame 10 through the cooperation of the pivot 40 and the pivot sleeve 60. The pivot 40 is hidden on the side of the door frame 10 facing the interior space of the tower, thus forming an inward-pushing tower door. With this structure, the tower door cannot be disassembled without bolts or a key, improving security and anti-theft performance. Furthermore, after opening, the door panel 20 can be automatically locked by the locking component 80 to prevent strong winds from closing the door, further enhancing its safety during use.

[0033] Continue to refer to Figure 1 and Figure 2In the specific configuration of the rotating shaft 40 and the rotating shaft sleeve 60, the rotating shaft 40 and the rotating shaft sleeve 60 are respectively fixedly connected to the door frame 10 and the door panel 20. In one feasible embodiment, a support block 50 is provided on the side of the door frame 10 facing the internal space of the tower, and the rotating shaft 40 is fixed to the support block 50. The rotating shaft 40 is fixedly connected to the door frame 10 by the fixing block, and a certain gap is maintained between the rotating shaft 40 and the door frame 10 to provide sufficient assembly space for the assembly of the rotating shaft sleeve 60.

[0034] When specifically setting up the support block 50 and the pivot 40, along the height direction of the door frame 10, the support block 50 is located below the pivot 40. For example... Figure 2 As shown, the support block 50 is a cuboid block, and the pivot 40 is fixed on the upper surface of the support block 50. When arranged, the upper surface of the support block 50 is larger than the end face of the pivot 40, so that when the pivot sleeve 60 is fitted onto the pivot 40, the support block 50 can provide a limit to support the door panel 20.

[0035] When the support block 50 is fixedly connected to the door frame 10, different connection methods can be used, such as welding, riveting, or fixed connection through threaded connectors (bolts or screws), as long as the connection strength between the support block 50 and the door frame 10 is guaranteed. When the pivot 40 is connected to the support block 50, it can also be fixedly connected by welding, or the pivot 40 and the support block 50 can be an integral structure.

[0036] In one feasible embodiment, the door panel 20 and the pivot sleeve 60 are connected by a support assembly 70. Specifically, a support assembly 70 that mates with the pivot sleeve 60 is provided on the door panel 20. This support assembly 70 includes two support plates 71, which are spaced apart along the height direction of the door panel 20. Each of the two support plates 71 is fixedly connected to the pivot sleeve 60. For example, one end of each support plate 71 is fixedly connected to the door panel 20, and the other end extends beyond the edge of the door panel 20. When fixedly connected to the pivot sleeve 60, the end of the support plate 71 extending beyond the door panel 20 is fixedly connected to the pivot sleeve 60. In one feasible embodiment, the two support plates 71 are fixedly connected to the two ends of the pivot sleeve 60 respectively to improve the support strength of the pivot sleeve 60.

[0037] In one feasible solution, the support plate 71 is welded to the door panel 20, and the support plate 71 is also welded to the pivot sleeve 60. Welding facilitates the fixed connection between the support plate 71, the door panel 20, and the pivot sleeve 60, and also provides the connection strength to ensure that the pivot sleeve 60 can stably support the door panel 20 when it is fitted onto the pivot 40.

[0038] Continue to refer to Figure 2To improve the structural strength of the connection between the door panel 20 and the door frame 10, multiple pivots 40 are used, and these multiple pivots 40 are spaced apart along the height direction of the door frame 10. For example... Figure 2 As shown, three pivots 40 are illustrated. These three pivots 40 respectively connect to the door panel 20 near both ends and the middle position in the height direction, providing reliable support for the door panel 20. When setting the pivot sleeves 60, the number of pivot sleeves 60 is the same as the number of pivots 40, and the pivot sleeves 60 and pivots 40 are fitted together in a one-to-one correspondence. It should be understood that the number of pivots 40 and pivot sleeves 60 is not limited to the three shown in the example above. In actual installation, the number of pivots 40 can be two, three, four, or other different numbers.

[0039] Please refer to the above. Figure 2 , Figure 3 and Figure 4 , Figure 3 It shows Figure 1 A magnified view of a portion of point A in the middle. Figure 4 It shows Figure 2 A partially enlarged schematic diagram at point B. The positioning component provided in this application embodiment includes a spring pin 81 and a locking hole 82. The spring pin 81 is disposed on the rotating shaft sleeve 60, while the locking hole 82 is formed on the rotating shaft 40. Specifically, the spring pin 81 passes through the side wall of the rotating shaft sleeve 60 and can be inserted into the hollow cavity of the rotating shaft sleeve 60. The locking hole 82 is formed on the side wall of the rotating shaft 40, and when the rotating shaft sleeve 60 is fitted onto the rotating shaft 40, the height of the spring pin 81 and the locking hole 82 are the same. During the process of the door panel 20 rotating from the closed state to the open state, when the door panel 20 is in the closed state, the spring pin 81 abuts against the side wall of the rotating shaft 40. As the rotating shaft 40 of the door panel 20 rotates, the rotating shaft sleeve 60 rotates relative to the rotating shaft 40. When the door panel 20 is opened to the set position, the spring pin 81 aligns with the locking hole 82 and is inserted into the locking hole 82, thereby locking the door panel 20. When it is necessary to unlock the door panel 20, the spring pin 81 can be pulled out from the locking hole 82 to rotate the door panel 20.

[0040] In one feasible embodiment, when there are multiple rotating shafts 40, a spring pin 81 is disposed on the middle rotating shaft sleeve 60 among the multiple rotating shaft sleeves 60, and a locking hole 82 is formed on the middle rotating shaft 40 among the multiple rotating shafts 40. When the locking assembly 80 is set up with this embodiment, the height of the locking assembly 80 is approximately the same as the height of the worker's hand, which facilitates the worker's operation.

[0041] Please refer to the above. Figure 2 and Figure 5 , Figure 5A schematic diagram of the structure of the sealing strip 30 cooperating with the door frame 10 is shown. To improve the sealing effect of the tower door, the tower door provided in this embodiment of the application further includes a sealing strip 30 disposed on the door frame 10 and used to seal the gap between the door panel 20 and the door frame 10. When fixing the tower door, the sealing strip 30 is fitted onto the inner edge of the door frame 10. With this structure, it is convenient to connect the sealing strip 30 to the door frame 10, and it is also convenient to replace the sealing strip 30.

[0042] This application embodiment also provides a wind turbine tower, which includes a tower and a tower door as described above, with the door frame 10 fixed to the tower.

[0043] In the above technical solution, the door panel and door frame are rotatably connected through the cooperation of a pivot and a pivot sleeve. The pivot is hidden on the side of the door frame facing the interior space of the tower, and the door cannot be disassembled without bolts or a key, thus improving anti-theft performance. Furthermore, the door panel can be automatically locked by a locking component after opening, preventing strong winds from closing the door.
