Description

A segmented wind turbine tower storage rack Technical Field

[0001] This utility model belongs to the field of wind power technology, specifically a segmented wind turbine tower storage bracket. Background Technology

[0002] Wind turbine towers are a crucial component of wind power generation equipment. Typically constructed from rolled and welded steel plates, they form a hollow cylindrical structure used to support the nacelle and blades of the wind turbine generator. Wind turbine towers play a critical role in the entire wind power system, providing load-bearing capacity, wind resistance, and maintaining the equipment's height. To ensure stable operation of the wind turbine at high altitudes, wind turbine towers require high strength and dimensional accuracy, resulting in a large structural size. Their diameter is typically 4-5 meters, their length between 20-30 meters, and their overall weight is extremely high.

[0003] Chinese utility model patent CN205394493U describes a wind turbine tower with a diameter of 4-5m and a length of 20-30m. Currently, after manufacturing, these towers are simply stacked in the workshop, making them prone to rolling. Due to the large mass of the wind turbine towers, this could damage workshop equipment or workers, which is detrimental to workshop management and safe production. This patent solves the problem of using wind turbine towers for temporary storage to prevent them from rolling and causing safety accidents.

[0004] However, the support device is an open structure and lacks full coverage protection for the tower end face and outer surface. During long-term storage, the tower is easily affected by external environmental factors such as dust and rain, which can lead to external surface pollution or even corrosion, affecting the service life of the tower and the quality of subsequent construction. Summary of the Invention

[0005] The purpose of this utility model is to provide a segmented wind turbine tower storage bracket to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] A segmented wind turbine tower storage rack is provided, comprising several support components, each of which is equipped with a protective component. Adjacent protective components are interlocked by connecting components, and end caps can be detachably connected to the first and last protective components.

[0007] Furthermore, the support assembly includes a main support frame, on which a support plate is provided. The support plate is an arc-shaped plate with an arc radius that matches the outer diameter of the wind turbine tower being stored. The arc surface faces upward and can fit against the outer arc surface of the tower, thereby providing a larger contact support area, effectively dispersing the weight of the tower, and avoiding structural damage caused by point contact. A rubber anti-slip pad can be attached to the surface of the support plate to absorb micro-vibrations, enhance friction, and further protect the outer wall surface of the tower from scratches or wear.

[0008] Furthermore, several V-shaped support arms are provided on both sides of the main support frame to enhance the overall structural stability of the bracket and provide multi-point lateral support for the support plate.

[0009] Furthermore, the protective assembly includes a lower cover, which is mounted on the main support frame. An upper cover is mounted on the lower cover, and two adjacent upper covers are interlocked by connecting components. The lower cover is then installed onto the main support frame, ensuring that the arc-shaped surface fits snugly against the arc of the tower bottom. The upper and lower covers are installed piece by piece and interlocked. Two adjacent upper covers are interlocked and locked together by connecting components to form a continuous closed arc surface. After all components are assembled, they together form a complete arc-shaped protective cover that wraps around the end of the tower, preventing rainwater, dust, debris, etc. from entering.

[0010] Furthermore, a snap-fit ​​plate is provided on the lower cover, and a plug-in seat is provided on the upper cover. The snap-fit ​​plate snaps into the plug-in seat, and the snap-fit ​​plate is inserted longitudinally into the snap-fit ​​groove in the plug-in seat. After being inserted to the bottom, the snap-fit ​​plate is locked in the plug-in seat and is not easy to loosen. In order to enhance the connection firmness, the snap-fit ​​plate only needs to be pulled upward when disassembling. The structure is simple, the maintenance is convenient, and it effectively prevents the upper cover from loosening during transportation or use.

[0011] Furthermore, the connecting component includes a guide limiting post, which is disposed on one side of the upper part of the upper cover. A receiving sleeve is provided on one side of the upper part of the upper cover. The guide limiting post is snapped into the receiving sleeve, and the receiving sleeve is snapped into the guide limiting post. The guide limiting post is inserted into the receiving sleeve to form a snap-fit ​​connection, forming a stable mating relationship. This structure can realize the rapid assembly and precise positioning of the protective components, prevent misalignment or detachment between upper covers, and facilitate installation and subsequent maintenance.

[0012] Furthermore, the upper cover and the lower cover are provided with several mounting holes on one side of the upper part. The two upper covers and the lower cover are detachably connected to each other through the mounting holes. The upper cover and the lower cover together usually form the outer shell of the equipment. The installation of the end cover can seal the opening of the cover, prevent dust and impurities from entering the inside of the equipment, and protect the storage safety of the internal tower.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The large protective cover is broken down into multiple modular arc-shaped protective pieces that are easy to transport and assemble. These pieces are then combined using connecting components to form a complete protective ring around the tower. The structure has good rigidity and sealing properties, and is easy to install and disassemble quickly on site. The protective components cover the end face of the tower.

[0015] Through support components, protective components, and connecting components, stable support and full end-face protection of the tower are achieved during temporary or long-term storage, preventing the tower surface from being affected by external environmental factors such as dust and rain, thereby improving the preservation quality and service life of the wind turbine tower.

[0027] Please refer to Figures 1-3. In this embodiment of the present invention, a segmented wind turbine tower storage bracket includes several support components 1, each of which is provided with a protective component 2. Adjacent protective components 2 are interlocked with each other by a connecting component 3.

[0028] Support component 1 is used to support the wind turbine tower body. Protective component 2 is set on support component 1, preferably with an arc-shaped cover structure, to cover the end section of the wind turbine tower. Protective component 2 adopts a segmented structure. Two adjacent protective components 2 are spliced ​​together by connecting component 3 to form a complete protective ring around the tower. Connecting component 3 is used to realize the connection between adjacent protective components 2. Through the assembly of connecting component 3, adjacent protective components 2 can be quickly assembled and connected to form a continuous and closed protective surface, ensuring the stability and protective integrity of the entire structure.

The end cover plate 101 can be detachably connected to both sides of the first and last protective components 2 to form a fully enclosed structure, effectively preventing the inside of the tower from being polluted by rainwater, dust and other environmental factors.

[0029] On-site, support components 1 are pre-arranged according to the tower diameter; protective components 2 are then placed piece by piece on the support components 1 and spliced ​​in sequence; adjacent protective components 2 are securely connected using connecting components 3; end caps 101 are installed at both ends to form a closed protective structure. Through the support components 1, protective components 2, and connecting components 3, stable support and full end-face protection of the tower are achieved during temporary or long-term storage, preventing the tower surface from being affected by external environmental factors such as dust and rain, thus improving the preservation quality and service life of the wind turbine tower. The segmented modular design makes assembly convenient, the structure reliable, and transportation and unloading more efficient, making it suitable for wind turbine tower manufacturing, transportation, and other application scenarios.

[0030] In one embodiment, as shown in Figures 1 and 2, the support assembly 1 includes a main support frame 11, on which a support plate 12 is provided. The main support frame 11 is a steel structure frame, which can be integrally welded or a profile splicing structure, providing an overall load-bearing foundation for supporting and positioning the protective assembly 2 and the tower. The support plate 12 is located on the upper part of the main support frame 11. The support plate 12 is an arc-shaped plate, and its arc radius is adapted to the outer diameter of the wind turbine tower on which it is stored. Its arc surface faces upward and can fit against the outer arc surface of the tower, thereby providing a larger contact support area, effectively dispersing the weight of the tower, and avoiding structural damage caused by point contact. The surface of the support plate 12 can be attached with a rubber anti-slip pad to absorb micro-vibrations, enhance friction, and further protect the outer wall surface of the tower from scratches or wear.

[0031] In one embodiment, as shown in Figures 1 and 3, a plurality of V-shaped support arms 13 are provided on both sides of the main support frame 11. The V-shaped support arms 13 on both sides of the main support frame 11 are used to enhance the overall structural stability of the bracket and provide multi-point lateral support for the support plate 12.

[0032] In one embodiment, as shown in Figures 1 and 3, the protective component 2 includes a lower cover 21, which is mounted on the main support frame 11. An upper cover 22 is mounted on the lower cover 21. Two adjacent upper covers 22 are interlocked by a connecting component 3. The lower cover 21 is mounted on the main support frame 11 (or its support plate 12) to form the bottom arc-shaped base of the protective component 2. The upper cover 22 is an upwardly extending arc-shaped protective plate structure used to cover the upper and side parts of the wind turbine tower end. The connecting component 3 is used to realize the mechanical connection between two adjacent upper covers 22. The lower cover 21 is installed on the main support frame 11 to ensure that the arc surface fits the arc of the bottom of the tower. The upper covers 22 are installed piece by piece and interlocked with the lower cover 21. Two adjacent upper covers 22 are interlocked and locked by the connecting component 3 to form a continuous closed arc surface. After all the components are assembled, the protective components 2 together form a complete arc-shaped protective cover, which wraps around the end of the tower to prevent rainwater, dust, debris, etc. from entering.

[0033] In one embodiment, as shown in Figures 2 and 3, a snap-fit ​​plate 211 is provided on the lower cover 21, and a plug-in seat 221 is provided on the upper cover 22. The snap-fit ​​plate 211 is snapped into the plug-in seat 221, and the lower cover 21 is installed on the support plate 12.
