Tower drum section, tower, wind turbine, mold, and forming method

A tower, comprising:

• two or more tower drum sections, wherein the two or more tower drum sections are disposed coaxially, and each two adjacent tower drum sections of the two or more tower drum sections are connected to each other, wherein each tower drum section comprises:
• a drum section base, comprising two or more tower drum pieces successively distributed along a circumferential direction of the drum section base;
• and
• a connecting assembly,
• wherein in the circumferential direction, two adjacent tower drum pieces are connected by the connecting assembly,
• wherein the connecting assembly comprises a first connecting member and a second connecting member, the first connecting member comprises an adapter portion and an anchoring portion that are located inside a first one of the two adjacent tower drum pieces, and the second connecting member is at least partially located inside a second one of the two adjacent tower drum pieces,
• wherein the adapter portion is connected to the second connecting member, and the anchoring portion is connected to the adapter portion on a first side of the adapter portion facing away from the second connecting member,
• wherein the adapter portion comprises a first adapter sleeve and a second adapter sleeve,
• wherein the anchor portion on the first side of the adapter portion extends at least partially into the first adapter sleeve through an end of the first adapter sleeve, and
• wherein the first adapter sleeve is connected to the second adapter sleeve, and the second connecting member on a second side of the adapter portion extends into the second adapter sleeve through an end of the second adapter sleeve that is away from the first adapter sleeve.

A wind turbine, comprising:

• a generator;
• and
• a tower, wherein the generator is disposed on the tower, wherein the tower comprises:
• two or more tower drum sections, wherein the two or more tower drum sections are disposed coaxially, and each two adjacent tower drum sections of the two or more tower drum sections are connected to each other, wherein each tower drum section comprises:
• a drum section base, comprising two or more tower drum pieces successively distributed along a circumferential direction of the drum section base;
• and
• a connecting assembly, wherein in the circumferential direction, two adjacent tower drum pieces are connected by the connecting assembly,
• wherein the connecting assembly comprises a first connecting member and a second connecting member, the first connecting member comprises an adapter portion and an anchoring portion that are located inside a first one of the two adjacent tower drum pieces, and the second connecting member is at least partially located inside a second one of the two adjacent tower drum pieces,
• wherein the adapter portion is connected to the second connecting member, and the anchoring portion is connected to the adapter portion on a first side of the adapter portion facing away from the second connecting member,
• wherein the adapter portion comprises a first adapter sleeve and a second adapter sleeve,
• wherein the anchor portion on the first side of the adapter portion extends at least partially into the first adapter sleeve through an end of the first adapter sleeve, and
• wherein the first adapter sleeve is connected to the second adapter sleeve, and the second connecting member on a second side of the adapter portion extends into the second adapter sleeve through an end of the second adapter sleeve that is away from the first adapter sleeve.
