Detailed Description

To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:

referring to fig. 1-4, a tower barrel component with stably connected upper and lower barrel sections comprises an upper tower barrel 1 and a lower tower barrel 2, wherein the upper tower barrel 1 and the lower tower barrel 2 are connected through a bolt group 3, and a cambered surface gasket 4 is arranged between the outer side walls of the upper tower barrel 1 and the lower tower barrel 2 and the bolt group 3; a convex ring 5 which is integrated with the lower tower drum 2 into a whole is arranged in the middle of the upper end face of the lower tower drum 2, an annular groove 6 which is integrated with the upper tower drum 1 into a whole is arranged in the middle of the upper end face of the upper tower drum 1, and the annular groove 6 and the convex ring 5 are the same in width; the inner side wall of the lower tower barrel 2 is lower than the outer side wall, and the inner side wall of the upper tower barrel 1 is longer than the outer side wall; the upper tower barrel 1 is arranged above the lower tower barrel 2 through a convex ring 5 clamped in an annular groove 6, and a plurality of bolt groups 3 are arranged at the connection positions at equal angles; the upper tower barrel 1 and the lower tower barrel 2 are both provided with threaded holes 7 which are matched with each other, and connecting lines of the outer side walls of the upper tower barrel 1 and the lower tower barrel 2 above the threaded holes 7 are arranged in a vertically staggered manner by taking boundary lines as boundary lines; the cambered surface gasket 4 is respectively connected with the upper and lower two adjacent threaded holes 7 and is arranged in parallel.
