[0058] In some embodiments, the connecting assembly 3 further comprises a gasket (not shown) which is arranged on the connecting member 32 and between the inner wall surface of the tower drum and the end plate 12 to prevent loosening between the end plate 12 and the inner wall surface of the tower drum.

[0059] Optionally, the gasket is a spring washer, and the gasket is arranged around the connecting member 32, and when the end plate 12 is installed on the inner wall surface of the tower drum through the connecting member 32, the gasket is compressed and tightly attached to the inner wall surface of the tower drum and the side surface of the end plate 12, which can effectively prevent the support 11 from loosening during long-term use.

[0060] In some embodiments, the support 11 comprises a connecting rod body 111 and a first rod body 112. One end of the first rod body 112 is connected with the connecting rod body 111, and the other end of the first rod body 112 extends away from the connecting rod body 111 and is provided with the end plate 12.

[0061] Specifically, the central axis of the first rod body 112 is collinear with the perpendicular bisector of the connecting rod body 111, which increases the contact area of one end of the first rod body 112 with the connecting rod body 111, so that the first rod body 112 is firmly connected with the connecting rod body 111, and the gravity center of the connecting rod body 111 and the gravity center of the first rod body 112 are collinear with the central axis of the first rod body 112, which improves the stability of the structure of the support 11 and the reliability of the installation of the support 11 on the tower drum. Moreover, the structure of the support 11 is simple, easy to manufacture, and cost-saving.

[0062] When the support 11 is installed, the first rod body 112 extends along the radius of the tower drum, which increases the contact area between the end plate 12 arranged on the first rod body 112 and the inner wall surface of the tower drum, and improves the connection strength between the first rod body 112 and the inner wall surface of the tower drum.

[0063] In some embodiments, the cross-sectional area of one end of the first rod body 112 is smaller than the cross-sectional area of the other end of the first rod body 112, which increases the contact area of the other end of the first rod body 112 with the end plate 12, so that the other end of the first rod body 112 is firmly connected with the inner wall surface of the tower drum.

[0064] In some embodiments, the bracket 11 further comprises a second rod body 113, one end of the first rod body 112 and one end of the second rod body 113 are respectively arranged at two ends of the connecting rod body 111 and connected with the connecting rod body 111, the other end of the first rod body 112 and the other end of the second rod body 113 are both extended towards the direction away from the connecting rod body 111, and the other end of the first rod body 112 and the other end of the second rod body 113 are both provided with an end plate 12.
