For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Please refer to Figure 1 , the present utility model provides a technical solution:

[0029] A tower barrel, comprising a tower barrel main body 1, a main support plate 4 is arranged at the center of the bottom of the tower barrel main body 1, an extension plate 5 is arranged at the top corner of the main support plate 4, a sealing plate 6 is arranged along the outside of the top of the extension plate 5, and a plurality of auxiliary support frames 2 are obliquely arranged on the surface of the tower barrel main body 1, and auxiliary support plates 3 are arranged at the bottoms of the plurality of auxiliary support frames 2.

[0030] Further, fixing openings 7 are formed through both sides of the top of the main support plate 4.

[0031] Specifically, a plurality of auxiliary support frames 2 are arranged at the bottom of the surface of the tower barrel main body 1, and a triangular stable structure is formed between the auxiliary support frames 2 and the tower barrel main body 1, thereby improving the overall stability of the tower barrel.

[0032] Please refer to Figures 2 - 5 This utility model provides a technical solution: a support structure for a wind turbine tower barrel, comprising the above-mentioned tower barrel and a fixed bearing platform 8. A second through hole 13 is formed at the center of the top of the fixed bearing platform 8. The main support plate 4 is arranged at the bottom of the second through hole 13. The surface of the second through hole 13 is in contact with the extension plate 5. The bottom of the sealing plate 6 is in contact with the top of the fixed bearing platform 8. A plurality of first through holes 12 are arranged on the top of the fixed bearing platform 8 and outside the second through hole 13. The auxiliary support plate 3 is arranged at the bottom of the first through hole 12. The second concrete 10 is filled in the first through hole 12. Anchor bolts 11 are arranged at the fixing openings 7. The first concrete 9 is filled in the second through hole 13.

[0033] Specifically, before installation, the factory will produce the tower barrel main body 1 as shown in Figure 1 . Then, the on-site construction personnel will produce a fixed bearing platform 8 with matching dimensions according to the drawings. The diameters of the first through hole 12 and the second through hole 13 with openings in the fixed bearing platform 8 respectively match the main support plate 4 and the auxiliary support plate 3. After completion, the main support plate 4 is inserted into the second through hole 13, and the auxiliary support plate 3 is inserted into the first through hole 12. Then, through the prior art, the main support plate 4 and the auxiliary support plate 3 are fixed to the fixed bearing platform 8 through the anchor bolts 11.

[0034] Then, the second concrete 10 and the first concrete 9 are respectively filled at the first through hole 12 and the second through hole 13 to separate the anchor bolts 11 from the environment and prevent rusting.

[0035] Further, a first waterproof sealing strip 14 is adhered to the gap between the top of the sealing plate 6 and the first concrete 9.

[0036] Further, a second waterproof sealing strip 15 is adhered to the gap between the outside of the sealing plate 6 and the fixed bearing platform 8.

[0037] It should be noted that, in addition, a third waterproof sealing strip is adhered to the gap between the second concrete 10 and the fixed bearing platform 8, so that the connection between the tower main body 1 and the fixed bearing platform 8 is waterproofed by the waterproof sealing strip, preventing water from entering the first through hole 12 and the second through hole 13 from the gap. Since the auxiliary support plate 3 and the main support plate 4 are fixed through the anchor bolts 11 in the first through hole 12 and the second through hole 13 respectively, if water enters from the gap, it will cause the anchor bolts 11 to rust and affect the stability of the overall connection of the wind turbine generator set.

[0038] Furthermore, the anchor bolt 11 includes an anchor bolt rod 16, a waterproof ring 18, a gasket 20, and a nut 21. A first backing plate 17 is provided at the top surface of the anchor bolt rod 16. A waterproof ring 18 is provided at the top of the first backing plate 17 and sleeved on the anchor bolt rod 16. A second backing plate 19 is provided at the top of the waterproof ring 18 and located at the anchor bolt rod 16. A gasket 20 and a nut 21 are sleeved on the surface of the anchor bolt rod 16 and located at the top of the second backing plate 19. The nut 21 is located above the gasket 20.

[0039] Specifically, by providing the waterproof ring 18 in the anchor bolt 11, the waterproof performance of the bolt 11 can be improved through the waterproof ring 18.

[0040] Furthermore, the bottom of the first backing plate 17 is located on the top surfaces of the main support plate 4 and the auxiliary support plate 3.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
