Description
Technical Field
[0001] This utility model relates to the field of wind power technology, specifically to a wind power tower conversion section that is easy to transport. Background Technology
[0002] As the hub height of wind turbine generators continues to increase, the traditional single-tube steel tower structure faces challenges. To adapt to the ever-increasing hub height requirements, the wind power industry has successively developed truss-type wind turbine generator solutions. This tower structure has a support frame at the bottom and a tower tube directly or indirectly connected to the top. The support frame and the tower tube are connected through a tower transition section. Due to the large number of steel pipes in the existing transition section structure and its large volume, considering the transportation size, the steel pipes often need to be pre-disassembled and then transported to the construction site for assembly. The problem is that there are many scattered steel pipe units to be assembled, making the assembly process cumbersome and resulting in slow construction progress. Summary of the Invention
[0003] The purpose of this invention is to provide a conveniently transportable wind power tower conversion section to solve the problems mentioned in the background art.
[0004] This utility model provides a conveniently transportable wind power tower conversion section, comprising an upper conversion support section and a lower conversion support section. The upper conversion support section includes an upper mounting support plate and inclined support plates I. The upper mounting support plate is a rectangular plate with a circular hole in its center, into which a conversion section flange is installed. Four inclined support plates I are provided, with their upper edges connected to the four sides of the upper mounting support plate. The sides of adjacent inclined support plates I are sequentially fixedly connected. A slot I is formed on the lower center of each of the four inclined support plates I, dividing the bottom of each plate into four triangular legs I. Upper support connecting plates are fixed to the outer bottom of each triangular leg I. The upper support connecting plates are evenly distributed with… The lower conversion support section includes four inclined support plates II, whose sides are sequentially fixedly connected. A flange for the lower conversion support section is fixed to the top of each of the four inclined support plates II. A slot II is formed on the lower middle side of each of the four inclined support plates II, dividing the bottom of each plate into four triangular legs II. A lower support connecting plate is fixed to the outer bottom of each triangular leg II. Multiple connection holes are evenly distributed on the lower support connecting plate. In the transport state, the upper conversion support section retracts into the lower conversion support section; in the installation state, the upper conversion support section extends out from the lower conversion support section, and its lower end is connected to its upper end.
[0005] Both slot I and slot II are trapezoidal slots, and the height of slot I and slot II does not exceed the centerline of inclined support plate I and inclined support plate II.
[0006] The upper support connecting plate is located below the lower conversion support section flange, and multiple connecting bolts are fixed on the lower conversion support section flange, with the ends of each connecting bolt pointing downwards.
[0007] The four inclined support plates I are parallel to the four corresponding inclined support plates II.
[0008] The cross-sections of the upper and lower conversion support sections gradually decrease from bottom to top, so that the upper and lower conversion support sections as a whole have a frustum-shaped structure.
[0009] This utility model provides a convenient transportable wind power tower conversion section. Its advantages lie in the fact that it is equipped with an upper conversion support section and a lower conversion support section. In the transport state, the upper conversion support section retracts into the lower conversion support section, thus reducing its size and facilitating transportation. In the installation state, the upper conversion support section extends from the lower conversion support section, and its lower end connects to the upper end of the lower conversion support section, thereby realizing the extension and installation of the telescopic conversion section. This facilitates assembly, ensures reliable connection, solves the problem of large transition section size and difficult transportation, effectively reduces transportation costs, and is simple and efficient to install.

[0012] Example Reference Figures 1-2This embodiment provides a conveniently transportable wind power tower conversion section, comprising an upper conversion support section 1 and a lower conversion support section 2. The upper conversion support section 1 includes an upper mounting support plate 5 and inclined support plates I. The upper mounting support plate 5 is a rectangular plate with a circular hole in its center. A conversion section flange 6 is installed in the circular hole. There are four inclined support plates I, with the upper edges of the four inclined support plates I respectively connected to the four sides of the upper mounting support plate. The sides of two adjacent inclined support plates I are sequentially fixedly connected. Each of the four inclined support plates I has a slot I7 on its lower center, which divides the bottom of the four inclined support plates I into four triangular legs I8. An upper support connecting plate is fixed to the outer bottom of each triangular leg I8. The upper support connecting plate has multiple connecting holes evenly distributed on it. The lower conversion support section 2 includes four... The inclined support plate II consists of four inclined support plates II, whose sides are sequentially fixedly connected. A lower conversion support section flange 4 is fixed to the top of each of the four inclined support plates II. A slot II9 is opened on the lower middle side of each of the four inclined support plates II, dividing the bottom of the four inclined support plates II into four triangular support legs II10. A lower support connecting plate 3 is fixed to the outer bottom of each triangular support leg II10. Multiple connecting holes are evenly distributed on the lower support connecting plate 3. In the transportation state, the upper conversion support section 1 retracts into the lower conversion support section 2, thus reducing its size and facilitating transportation. In the installation state, the upper conversion support section extends from the lower conversion support section, and its lower end connects to the upper end of the lower conversion support section, thereby realizing the extension and installation of the telescopic conversion section. Assembly is convenient and the connection is reliable.
[0013] Both slot I and slot II are trapezoidal slots, and the height of slot I and slot II does not exceed the centerline of inclined support plate I and inclined support plate II.
[0014] The upper support connecting plate is located below the lower conversion support section flange 4. The upper support connecting plate is not shown in the diagram, but its structure and connection method are the same as the lower support connecting plate 3. Multiple connecting bolts are fixed to the lower conversion support section flange 4, with the ends of each bolt pointing downwards. In the installation state, the upper support connecting plate and the lower conversion support section flange 4 are fixedly connected by the connecting bolts, thereby fixing the upper conversion support section 1 and the lower conversion support section 2.
[0015] The four inclined support plates I are parallel to the four corresponding inclined support plates II.
[0016] The cross-sections of the upper conversion support section 1 and the lower conversion support section 2 gradually decrease from bottom to top, so that the upper conversion support section and the lower conversion support section as a whole have a frustum-shaped structure, which further improves the structural stability and reliability of the conversion section.
[0017] During installation and use, the upper end of the support frame is connected to the lower end of the lower conversion support section 2, and the upper end of the upper conversion support section 1 is connected to the lower end of the tower. The structure is stable and reliable, meeting the installation requirements of megawatt-class wind turbine units. The lower end of the lower conversion support section 2 is equipped with four triangular legs II10, each corresponding to one of the four corners of the support frame. A lower support connecting plate 3 is fixed to the outer side of the lower end of each triangular leg II10, and the support frame is fixedly connected via the lower support connecting plate 3 and bolts. A circular hole is opened in the center of the upper mounting support plate 5, and a conversion section flange 6 is installed in the circular hole. The flange at the lower end of the tower is connected to the conversion section flange 6, thereby achieving stable and reliable installation of the tower on the conversion section.
