[0023] It should be noted that, since the resistance at the top is greater than that at the bottom, the sizes of the two upper rotating assemblies are smaller than the sizes of the two lower rotating assemblies, in order to make the power generation efficiency of the four rotating assemblies the same.

[0024] Among them, an anti-falling block is fixedly installed on the top of the connecting rod 3, so as to achieve the purpose of preventing the supporting rod 4 from falling off, thereby making the supporting rod 4 safer when in use.

[0025] By adopting the above technical solution, a mounting mechanism is provided, which can stably mount the wind turbine body, thereby preventing the wind turbine from tipping over when used in harsh environments, thereby avoiding danger to personnel and improving the practicality and safety of the vertical axis wind turbine.

[0026] It should be added that the vertical axis wind turbine in the present invention is suitable for use by household users, and thus needs to be stably installed.

[0027] Example 2: Please refer to Figure 1-2 On the basis of the first embodiment, the installation mechanism includes a screw rod 801 rotatably installed between the left and right side walls of the inner cavity of the installation box 1, the outer surface of the screw rod 801 is threadedly connected to two screw blocks 802, the bottoms of the two screw blocks 802 are fixedly installed with a moving rod 803 with one end penetrating and extending to the outside of the installation box 1, the opposite sides of the two moving rods 803 are fixedly installed with a mounting column 804, the opposite sides of the two mounting columns 804 are fixedly installed with a clamping block 805, the outer surface of the screw rod 801 is fixedly installed with a No. 1 conical tooth 806, and the top of the installation box 1 is rotatably installed with a moving rod 803 with one end penetrating and extending to the outside of the installation box 1. A rotating rod 807 extends into the interior thereof, a second conical tooth 808 is fixedly installed at the bottom of the rotating rod 807, the outer surface of the first conical tooth 806 is meshed with the outer surface of the second conical tooth 808, a limit frame 809 is fixedly installed on the top of the installation box 1, a clamping rod 810 with one end passing through and extending to the outside thereof is movably installed on the left side of the limit frame 809, a movable plate 811 is fixedly installed on the outer surface of the clamping rod 810, a spring 812 is movably installed on the outer surface of the clamping rod 810, and the left and right ends of the spring 812 are respectively fixedly connected to the left side wall of the inner cavity of the limit frame 809 and the left side of the movable plate 811.

[0028] Among them, a slider is fixedly installed on the top of the screw block 802, and two sliding grooves are opened on the inner top wall of the installation box 1. The outer surfaces of the two sliders are slidably connected with the inner walls of the two sliding grooves respectively, so as to achieve the purpose of limiting the two screw blocks 802, so that the two screw blocks 802 can move left and right.

[0029] The outer surface of the screw rod 801 is provided with two kinds of threads, which are in opposite directions. The function of the two threads is to enable the screw rod 801 to drive the two screw blocks 802 to move in opposite directions at the same time, thereby clamping the wind turbine generator at the same time.

[0030] A limit slot is provided on the left side of the rotating rod 807, and the size of the clamping rod 810 matches the size of the limit slot. The purpose is to limit the rotating rod 807 so that the rotating rod 807 will not rotate after use, and the wind turbine can be stably installed.

[0031] Among them, fixing grooves are opened on the left and right sides of the fixing block 7. The sizes of the two fixing grooves are respectively matched with the sizes of the two clamping blocks 805, which can fix the wind turbine and make the wind turbine remain stable when in use.

[0032] In addition, the fixing block 7 is a prior art and is fixedly connected to the ground. The wind turbine generator can be placed above the fixing block 7, thereby stably installing the wind turbine generator.

[0033] By adopting the above technical solution, the purpose of stably installing the wind turbine is achieved by setting the coordination between the screw rod 801, two screw blocks 802, the movable rod 803, the mounting column 804, the clamping block 805, the No. 1 conical tooth 806, the rotating rod 807 and the No. 2 conical tooth 808, so that the wind turbine can remain stable during use. By setting the coordination between the limit position frame 809, the clamping rod 810, the movable plate 811 and the spring 812, the rotating rod 807 can be fixed, so that the rotating rod 807 will not rotate after use, thereby making the wind turbine more stably installed.

[0034] The working principle of the above embodiment is:

[0035] When the wind turbine needs to be fixed, first place the installation box 1 above the fixing block 7, then pull the clamping rod 810 to move the clamping rod 810 out of the limiting groove, and at the same time, the clamping rod 810 drives the movable plate 811 to move and squeeze the spring 812. After the clamping rod 810 is completely moved out of the limiting groove, rotate the rotating rod 807 so that the rotating rod 807 drives the second conical tooth 808 to rotate, the second conical tooth 808 drives the first conical tooth 806 to rotate, and the first conical tooth 806 drives the screw rod 801 to rotate, and the screw rod 801 drives the two screw blocks 802 to the opposite sides at the same time. The two screw blocks 802 respectively and simultaneously drive the two moving rods 803 to move to the opposite side, and the two moving rods 803 respectively and simultaneously drive the two installation columns 804 and the two clamping blocks 805 to move to the opposite side, so that the two clamping blocks 805 are respectively clamped with the two fixing grooves. When the two clamping blocks 805 are completely clamped with the two fixing grooves, the rotation of the rotating rod 807 is stopped, and then the clamping rod 810 is loosened, so that the spring 812 drives the clamping rod 810 to clamp with the limiting groove, thereby completing the installation of the wind turbine. Repeat the above steps in reverse to disassemble the wind turbine.
