The other end of the stretching assembly 8 is connected to the clamping block 702. It can be understood that a clamping groove that is adapted to the shape of the clamping block 702 is provided at the top of the tower 2. By setting the connection method between the clamping block 702 and the clamping groove, the nacelle 3 and the tower 2 can be quickly positioned and connected, thereby reducing the situation where the nacelle 3 is placed on the tower 2 and is affected by wind and causes excessive deflection or shaking.

[0029] For details, please refer to Figure 3 , Figure 4 , Figure 5On the basis of the above embodiment, the stretching component 8 includes a support rod 801, a wire wheel 802 and a pull rope 803. A plurality of support rods 801 are arranged on the support frame 601, and a plurality of support rods 801 are arranged on the wire wheel 802. The pull rope 803 is wound around the wire wheel 802, and one end of the pull rope 803 is connected to the telescopic plate 602, and the other end of the pull rope 803 is connected to the clamping component 7. It can be understood that in the process of the crane lifting the cabin 3, when the hoist squeezes the telescopic plate 602, the pull rope 803 can be used to realize the movement of the clamping block 702, thereby realizing the unlocking action of the clamping block 702 when the telescopic plate 602 is squeezed, and the clamping action of the clamping block 702 is realized when the telescopic plate 602 is released.

[0030] For details, please refer to Figure 4 , Figure 5 On the basis of the above embodiment, it also includes a cylindrical groove. A cylindrical groove is opened on the side of the clamping block 702 close to the second spring 703. One end of the second spring 703 extends into the cylindrical groove and is connected to the clamping block 702. It can be understood that one end of the second spring 703 is extended into the clamping block 702, which can provide a certain guiding effect when the second spring 703 is compressed, and at the same time, increase the movable distance between the clamping block 702 and the fixed plate 701.

[0031] For details, please refer to Figure 2 , Figure 4 On the basis of the above embodiment, it also includes a guide rod 9. A plurality of guide rods 9 are arranged on the cabin 3. One end of the stretching component 8 passes through the guide rod 9 and is connected to the supporting component 6. The other end of the stretching component 8 passes through the guide rod 9 and is connected to the clamping component 7. It can be understood that by setting the guide rod 9, it can play a guiding role for the pull rope 803 during the movement of the pull rope 803.

[0032] For details, please refer to Figure 4 On the basis of the above embodiment, it also includes a limiting ring (not shown in the figure), two limiting rings are arranged on the support rod 801, and a guide wheel 802 is arranged between the two limiting rings; it can be understood that by setting the limiting ring, the position of the guide wheel can be effectively limited to prevent the guide wheel 802 from sliding on the support rod 801, and the guide rope 803 is pulled back and forth to reduce the service life of the rope 803.

[0033] For details, please refer to Figure 2 , Figure 4 On the basis of the above embodiment, a plurality of first threaded holes are opened on the nacelle 3, and a plurality of second threaded holes are opened on the tower 2. The plurality of first threaded holes and the plurality of second threaded holes are connected by bolts 10. It can be understood that through the above arrangement, a further stable connection between the tower 2 and the nacelle 3 can be achieved.

[0034] In summary, when a wind turbine is in use, the telescopic plate 602 is connected to the hook on the crane through a sling. The sling can specifically be a lifting ring and a steel wire rope. A number of lifting rings are arranged on the portion of the telescopic plate 602 protruding from the support frame 601, and the connection between the lifting ring and the hook is achieved through the steel wire rope. This ensures that when the hook lifts the cabin 3, the telescopic plate 602 moves in the direction of compression of the first spring 603. At the same time, the pull rope 803 is pulled, and the clamping block 702 moves in the direction of compression of the second spring 703. Then, the crane is controlled to move the cabin 3 closer to the top of the tower 2, so that the clamping block 702 is aligned with the clamping slot provided on the tower 2. After alignment, the cabin 3 is slowly lowered. After the bottom of the cabin 3 is completely in contact with the top of the tower 2, the hook is allowed to lift. After detaching from the wire rope, the telescopic plate 602 is reset under the action of the first spring 603, and the clamping block 702 is reset under the action of the second spring 703. At this time, the clamping block 702 is just stuck in the clamping slot, thereby realizing the rapid positioning and connection of the cabin 3 and the tower 2. At this time, the staff can manually pass the bolt 10 through the first threaded hole and the second threaded hole inside the tower 2 to further fix the cabin 3 and the tower 2. Through the above arrangement, the cabin 3 and the tower 2 can be quickly positioned and fixed after the cabin 3 is placed, without the need to use a crane to tow or adjust the cabin 3 all the time, which is convenient for subsequent staff to take further fixing measures. Compared with the traditional method of aligning the screw holes and then manually tightening, it is more secure overall.
