[0043] Specifically, the prefabricated curved column 31 includes two prefabricated bamboo poles 32 with opposite curvatures. The two prefabricated bamboo poles 32 are arranged opposite to each other, and the bottoms of the two prefabricated bamboo poles 32 are fixed by binding with hemp ropes; adjacent prefabricated bamboo poles 32 of adjacent prefabricated curved columns 31 are overlapped and assembled into a ring-shaped main skeleton 3.

[0044] In this embodiment, the prefabricated curved column 31 includes two prefabricated bamboo poles 32. The prefabricated bamboo poles 32 are fitted with the characteristics of bamboo materials through structural finite element analysis software, which can accurately simulate the stress and deformation conditions of the structure, and can be verified to ensure safety.

Finally, the foundation wooden piles are inserted into the ground to fix the ground ring beam 2 to the ground.

[0048] Specifically, a central support column 7 is arranged between the top ring beam 1 and the ground ring beam 2. The central support column 7 includes a central vertical pole 71. A plurality of curved support rods 72 are arranged in a ring shape on the top of the central vertical pole 71. The bottom of the support rod 72 is connected to the central vertical pole 71 by bolts.

[0056] In this embodiment, the sizes of the small blades 4 and the middle blades 5 fit together at the installation locations, and the small blades 4 and the middle blades 5 are installed at the installation locations between adjacent prefabricated curved columns 31 of the main frame 3 through rotating rods, and the rotating rods pass below the center of gravity of the small blades 4 and the middle blades 5, so that the upper parts of the small blades 4 and the middle blades 5 rotate downward under the action of their own gravity.

[0057] One end of the traction rope 81 is connected to the top of the small blade 4 or the middle blade 5, and the other end of the traction rope 81 passes through the first traction ring 82 and the second traction ring 83 in sequence, and is connected to the limit assembly through the pull ring 84, so that when the traction rope 81 is pulled downward, the upper part of the small blade 4 or the middle blade 5 rises upward, and when the traction rope 81 is released upward, the upper part of the small blade 4 or the middle blade 5 flips downward.

[0058] Specifically, the second traction ring 83 includes an annular plate 85 sleeved on the top of the central vertical pole 71 . Traction holes 86 are evenly opened on the circumference of the annular plate 85 , and the traction rope 81 passes through the traction holes 86 .

The traction rope 81 passes through the traction hole 86, so that the traction rope 81 is guided by the traction hole 86 and the traction rope 81 is placed after passing through the first traction ring 82.

[0060] Specifically, the limiting assembly includes a high-position limiting screw 87 and a low-position limiting screw 88 respectively arranged on the central vertical pole 71; the high-position limiting screw 87 and the low-position limiting screw 88 both include a plurality of tensioning screws 89 staggered and passing through the central vertical pole 71, and the tensioning screws 89 are fixed to the central vertical pole 71 by nuts, and limiting nuts are provided at both end ends of the tensioning screws 89.

[0061] In this embodiment, the limiting assembly includes two groups, namely a high-position limiting screw 87 and a low-position limiting screw 88, both of which are distributed from high to low on the central vertical pole 71, and the high-position limiting screw 87 and the low-position limiting screw 88 both include multiple tensioning screws 89, which are staggered and passed through the central vertical pole 71 and fixed by nuts, so that the pull ring 84 at the end of the traction rope 81 can be sleeved on the tensioning screw 89.

[0062] Furthermore, when the small blade 4 or the middle blade 5 needs to be opened, the pull ring 84 at the end of the traction rope 81 is sleeved on the tension screw 89 of the high-position limit screw 87 and locked by the limit nut to prevent the pull ring 84 from slipping.

[0063] When the small blade 4 or the middle blade 5 needs to be closed, the pull ring 84 at the end of the traction rope 81 is sleeved on the pulling screw 89 of the low-position limiting screw 88 and locked by the limiting nut to prevent the pull ring 84 from sliding off.
