[0002] A wind power tower barrel is the tower pole of a wind power generation unit, which mainly plays a supporting role in the wind power generation unit. Through the tower barrel, wind energy is converted into electric energy. When installing a wind power tower barrel, it needs to be connected through a flange. When the flange of the wind power tower barrel is in use, its safety and stability are relatively high. However, after installation, problems such as wind impact will occur at high altitudes. These changes and impacts may cause displacement at the connection, and in severe cases, it will affect the overall verticality of the tower barrel, resulting in the tower barrel being in an inclined state as a whole and affecting the overall safety performance.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0019] As Figures 1 to 3 shown, a preferred embodiment of the present invention is: a device for strengthening the connection of the tower barrel flange, including flange 1. A connection ring 2 is fixedly connected to the right end of flange 1 at the left end, and the right end of connection ring 2 is slidably connected to the left end of flange 1 at the right end. An outer sleeve assembly 3 is provided outside flange 1, and an inner sleeve assembly 4 is slidably connected to the inner side of outer sleeve assembly 3. A groove 5 is formed on the side of inner sleeve assembly 4 close to the flange. Connecting plates 6 are fixedly connected to both the front and rear ends of outer sleeve assembly 3, and the lower end of the connecting plate 6 located above is slidably connected to the upper end of the connecting plate 6 located below. By externally setting the outer sleeve assembly 3 and the inner sleeve assembly 4 to fix the two flanges 1 on both sides and compensate and limit the displacement during displacement, the overall stability and safety are improved.

[0020] A first limit block 7 is fixedly connected to the upper end of the connecting plate 6 located below, and a second limit block 8 is fixedly connected to the lower end of the connecting plate 6 located above. The first limit block 7 penetrates through the connecting plate 6 located above, and the outer side of the first limit block 7 is slidably connected to the inner side of the connecting plate 6 located above. The second limit block 8 penetrates through the connecting plate 6 located below, and the outer side of the second limit block 8 is slidably connected to the inner side of the connecting plate 6 located below. By the first limit block 7 and the second limit block 8, the connecting blocks 6 at the upper and lower ends are quickly positioned together, improving the assembly speed of installing the outer sleeve assembly 3.

[0021] A fixing block 9 is slidably connected to the lower end of the connecting plate 6 located below. Support rods 10 are fixedly connected to both the left and right ends of the lower end of the fixing block 9. A connecting block 11 is provided at the lower end of the fixing block 9. Deformation rods 12 are fixedly connected to both the left and right ends of the connecting block 11, and the end of the deformation rod 12 close to the fixing block 9 is fixedly connected to the lower end of the support rod 10. A screw 13 is screwed to the upper end of the connecting block 6 located above. By setting the deformation rod 12 and the support rod 10 into a component that can produce an expansion effect, the stability of the screw 13 in the connecting plate 6 after installation is improved.

[0022] The screw 13 passes through the connecting block 6, the fixing block 9 and the connecting block 11. The outer sides of the screws 13 are in screw connection with the inner sides of the fixing block 9 and the connecting block 11. A nut 14 is screwed on the outer side of the screw 13, and the upper end of the nut 14 is in sliding connection with the lower end of the connecting block 11. The screw 13 is fixed in the connecting plate 6 by the nut 1, thereby facilitating the fixing of the outer sleeve assemblies 3 at the upper and lower ends.

[0023] The working process of this embodiment is as follows: When in use, first put the inner sleeve assembly 4 on one side flange 1, then make the flanges 1 with the connecting rings 2 contact each other relatively, and fix them by conventional fixing methods. After fixing the flanges 1, move the inner sleeve assembly 4 with the groove 5 to the connection of the flanges 1 to cover the connection gap. At this time, snap the outer sleeve assembly 3 on the outside of the inner sleeve assembly 4. When snapping, the first limiting block 7 at the lower end contacts the connecting plate 6 at the upper end, and the second limiting block 8 at the upper end contacts the connecting plate 6 at the lower end, achieving the effect of rapid positioning. At this time, place the fixing block 9 with the tensioning assembly at the lower end of the lower connecting plate 6, insert the screw 13 from top to bottom into the connecting plate 6 until the screw 13 passes through the connecting block 11. Under the action of the screw 13, the connecting block 11 moves upward therein, and the connecting block 11 drives the deformation rod 12 to move upward together. During the movement, the upper support rod 10 is squeezed. Since the support rod 10 is made of deformable material, at this time, the support rod 10 deforms to the left and right sides, pushing the deformation rod 12 to both sides and changing the overall shape. When the screw 13 rotates, the connecting block 11 contacts the upper fixing block 9. At this time, the deformation rod 12 and the support rod 10 are in contact with each other under the action of the force, increasing the contact area with the lower connecting plate 6. Then just install the nut 14. By providing the outer sleeve assembly 3 that is convenient for installation on the outside, when the flange 1 is displaced and a gap appears under the impact of the external impact, the outer sleeve assembly 3 makes up for it.

[0024] The above embodiment is a preferred implementation solution of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the scope of the present invention patent.

And for the sake of clarity, some other elements have also been omitted in this application document. Those of ordinary skill in the art should be aware that these omitted elements may also constitute the content of the present invention.
