Technical Field

[0001] This utility model belongs to the field of wind turbine tower support technology, specifically relating to a protective support structure for a vibration-resistant wind turbine tower. Background Technology

[0002] A wind turbine tower is the support structure for wind power generation. It plays a supporting role in wind turbine generator sets and also absorbs vibrations from the generator set.

[0003] Wind turbine towers require a support structure during installation. Existing support structures include precast mounting bases in concrete. During installation, the wind turbine tower is hoisted onto the mounting base, aligning the mounting flange at the bottom of the wind turbine tower with the mounting flange on the mounting base. The two mounting flanges are then fixed together using multiple bolts. However, the connection between the wind turbine tower and the mounting base is entirely through multiple bolts, resulting in poor seismic resistance. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective support structure for an anti-vibration wind turbine tower, comprising: a prefabricated mounting base installed on a concrete foundation, a wind turbine tower body located above the mounting base, a plurality of fasteners for fixed connection provided at the connection between the wind turbine tower body and the mounting base, a plug-in portion inserted into the wind turbine tower body located at the top of the mounting base, and an annular groove for accommodating the wind turbine tower body located between the plug-in portion and the mounting base.

[0006] Preferably, the outer walls of the plug-in portion are provided with inward grooves, and each groove is provided with a positioning block. The plug-in portion is provided with a driving component connected to multiple positioning blocks. The driving component is used to drive multiple positioning blocks to synchronously abut against the inner wall of the wind turbine tower body.

[0007] Preferably, the driving component includes multiple screws, each screw being rotatably mounted on the axis of each groove. Each positioning block has a threaded hole for accommodating the screws. When the screws rotate, they drive the positioning blocks to push outward or retract inward within the groove.

[0008] Preferably, a rotating part is rotatably mounted on the top of the insertion part, and a main bevel gear is provided at the bottom of the rotating part. One end of each of the plurality of screws is provided with a driven bevel gear that meshes with the main bevel gear.

[0009] Preferably, the fastener includes a first mounting flange, a second mounting flange, and a plurality of fixing bolts.

[0010] Preferably, the second mounting flange is further provided with a plurality of reinforcing ribs for support, which are welded in a ring array to the outer wall of the wind turbine tower body.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] (1) This utility model transfers the force at the connection between the wind turbine tower body and the mounting base to the plug-in part by adding a plug-in part and an annular groove that are plugged into the wind turbine tower body. The plug-in part with columnar structure can improve the seismic resistance of the equipment.

[0013] (2) By adding multiple positioning blocks and driving components, the driving components drive the multiple positioning blocks to abut against the inner wall of the wind turbine tower body, thereby improving the stability of the wind turbine tower body installation, strengthening the stability of the connection between the plug-in part and the wind turbine tower body, and further improving the seismic resistance of the equipment.

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.

[0020] refer to Figure 1-3 As shown, the present invention provides a protective support structure for a vibration-resistant wind turbine tower, comprising: a mounting base 2 prefabricated and installed on a concrete foundation 1; a wind turbine tower body 6 above the mounting base 2; a plurality of fasteners for fixed connection at the connection between the wind turbine tower body 6 and the mounting base 2; a plug-in part 9 at the top of the mounting base 2 that plugs into the wind turbine tower body 6; and an annular groove 16 for accommodating the wind turbine tower body 6 between the plug-in part 9 and the mounting base 2.

[0021] As described above, when using the concrete foundation 1, mounting base 2, wind turbine tower body 6, multiple fasteners and plug-in part 9 provided by this utility model to hoist the wind turbine tower body 6 above the mounting base 2, during the descent of the wind turbine tower body 6, the plug-in part 9 is inserted into the wind turbine tower body 6, and the bottom end of the wind turbine tower body 6 is inserted into the annular groove 16. At this time, the wind turbine tower body 6 is connected to the mounting base 2 by multiple fasteners.

[0022] Furthermore, to facilitate the connection between the wind turbine tower body 6 and the mounting base 2, refer to Figure 1-4 As shown, the fasteners include a first mounting flange 3, a second mounting flange 4, and multiple fixing bolts 7. The first mounting flange 3 is welded to the outer wall of the top of the mounting base 2, and the second mounting flange 4 is welded to the outer wall of the bottom of the wind turbine tower body 6. Multiple mounting holes 8 are arranged in a ring array between the first mounting flange 3 and the second mounting flange 4, and the multiple fixing bolts 7 are installed in the corresponding mounting holes 8. When the wind turbine tower body 6 is placed on the mounting base 2, the mounting holes 8 on the first mounting flange 3 and the second mounting flange 4 are aligned, and the fixing bolts 7 are installed in the corresponding mounting holes 8, thereby fixing the first mounting flange 3 and the second mounting flange 4 together, facilitating the fixed installation of the wind turbine tower body 6 on the mounting base 2.

[0023] Furthermore, in order to improve the strength of the connection between the second mounting flange 4 and the wind turbine tower body 6, refer to Figure 1-2 and Figure 4 As shown, the second mounting flange 4 is also welded with multiple reinforcing ribs 5 in a circular array for support, and all the reinforcing ribs 5 are welded to the outer wall of the wind turbine tower body 6. The multiple reinforcing ribs 5 can improve the welding strength of the second mounting flange 4 on the wind turbine tower body 6.

[0024] In this utility model, combined with Figure 2-3 As shown, grooves 17 are provided inward on the outer walls of the plug-in part 9 in this embodiment. A positioning block 15 is movably provided in each groove 17. The plug-in part 9 is provided with a driving member connected to multiple positioning blocks 15.

Each positioning block 15 has a threaded hole 14 for accommodating the screw 13. When the screw 13 rotates, it drives the positioning block 15 to push outward or retract inward in the groove 17.

[0026] As described above, when using the positioning block 15 provided by this utility model, the positioning block 15 is embedded in the outer wall of the insertion part 9 through the groove 17. After the bottom end of the wind turbine tower body 6 is inserted into the annular groove 16, the driving component drives multiple positioning blocks 15 to move outward and abut against the inner wall of the wind turbine tower body 6, thereby improving the stability of the connection between the insertion part 9 and the wind turbine tower body 6.

[0027] Furthermore, in order to synchronously adjust the position of positioning block 15, refer to Figure 2 As shown, a rotating part 10 is rotatably mounted on the top of the insertion part 9.
