DETAILED DESCRIPTION

[0018] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as a limitation of the utility model.

[0019] As Figure 1 , Figure 2 , Figure 3 And Figure 4As shown, the utility model discloses a kind of foldable vertical axis wind turbine, including the column 1 of being installed on generator assembly, the outside of column 1 is equipped with multiple blades 2, first fixed seat 11 and second fixed seat 10 are uniformly installed on the inner side of blade 2, second fixed seat 10 is equipped with positioning groove, the outer ring surface of column 1 is installed with multiple third fixed seat 12, third fixed seat 12 and first fixed seat 11 are all movably installed with support 3, one end of column 1 towards generator assembly is threadedly connected with inner sleeve 6, one end of inner sleeve 6 is sleeved with fixed ring, the outer ring surface of fixed ring is equipped with multiple parallel surfaces 14, sleeve pipe 7 is all installed on parallel surface 14, support frame 5 is movably installed on sleeve pipe 7, and another end of support frame 5 is inserted into positioning groove.

[0020] In the embodiment, first fixed seat 11 is equipped with first shaft hole, and second fixed seat 12 is equipped with second shaft hole, and support 3 is arranged in frame type structure, and one end of support frame 5 is installed on first fixed seat 11 by penetrating first shaft hole, and the other end is installed on third fixed seat 12 by penetrating second shaft hole.

[0021] In the embodiment, multiple limit frames 4 are installed on column 1 close to first fixed seat 11, and one end of limit frame 4 is arranged in abutment with support 3;Outer sleeve 8 is threadedly connected to the outside of inner sleeve 6, and the one end of outer sleeve 8 is enlarged to form flange 9 outward, and the surface of flange 9 is protruded upward to form support ring 13, and support ring 13 is arranged in abutment with support frame 5;

[0022] By limit frame and support frame, support and support frame can be abutted inward, so that blade, support, support frame and column form a frame structure.

[0023] In the embodiment, support frame 5 is arranged in frame type structure, and the width of support frame 5 matches the width of positioning groove, so that support frame can be smoothly inserted into positioning groove, and the assembly stability between support frame and second fixed seat is increased.
