Abstract
Description
Technical Field
[0001] This application relates to the field of wind power technology, and in particular to a device for correcting the concavity of the wall of a wind turbine tower. Background Technology
[0002] As the supporting structure of wind turbines, the stability and safety of wind turbine towers directly affect the operating efficiency and service life of the turbines. Currently, the single-unit capacity of offshore wind turbine towers is increasing, leading to a corresponding increase in tower diameter. To reduce costs, the amount of steel used in the steel structure needs to be reduced, resulting in thinner tower walls. During manufacturing, inward concavity defects inevitably occur at the support locations, reducing the tower's load-bearing capacity and threatening the safe operation of the wind turbine. Therefore, developing an efficient and reliable wind turbine tower wall concavity correction device to improve correction efficiency is particularly important. Utility Model Content
[0003] The present invention introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0005] In view of this, embodiments of this application propose a device for correcting the concavity of the wind turbine tower wall, comprising:
[0006] Column;
[0007] An arc-shaped plate, which is detachably connected to one end of the column;
[0008] A jack, which is connected to the other end of the main body;
[0009] The jack is curved away from the bottom surface of the column.
[0010] In one feasible implementation, there are multiple arc-shaped plates, and the curvature of the different arc-shaped plates is different.
[0011] In one feasible implementation, the column comprises:
[0012] Multiple splicing sections are spliced together to form the column, and the top of the column is provided with an assembly part, to which the arc-shaped plate is connected.

[0024] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
[0027] like Figure 1 As shown in the figure, this application embodiment proposes a concave correction device for the wall of a wind turbine tower, comprising: a column 1; an arc plate 2, the arc plate 2 being detachably connected to one end of the column 1; and a jack 3, the jack 3 being connected to the other end of the main body; wherein the jack 3 is curved away from the bottom surface of the column 1.
[0028] The wind turbine tower wall concavity correction device provided in this embodiment includes a column 1, an arc-shaped plate 2, and a jack 3. Based on this, during use, before correction, the arc-shaped plate 2 is aligned with the concave part according to its position. The hydraulic jack 3 is then activated, causing the arc-shaped plate 2 to press against the concave part, gradually restoring the concave part to its original shape through gradual pressure increase. During the correction process, the positions of the column 1 and the jack 3 can be adjusted multiple times as needed until the concave part is completely corrected. This wind turbine tower wall concavity correction device is easy to manufacture, has low production cost, simple tooling structure, low operation difficulty, and strong operability.
[0029] Understandable, Figure 1 To better illustrate jack 3, the actual proportion of jack 3 has been increased. In actual use, the length of column 1 can be larger.
[0030] like Figure 1 As shown, in one feasible implementation, there are multiple arc-shaped plates 2, and the curvature of different arc-shaped plates 2 is different.
[0031] In this technical solution, each wind turbine tower wall concavity correction device can be equipped with an arc plate 2 of different curvature. Based on this, a suitable arc plate 2 can be selected according to the different concave areas and the different diameters of the wind turbine tower, so that the wind turbine tower wall concavity correction device can be adapted to wind turbine towers of different diameters, increasing the applicability of the wind turbine tower wall concavity correction device.
[0032] In one feasible implementation, the column 1 includes: a plurality of splicing sections 1014, the plurality of splicing sections 1014 being spliced together to form the column 1, the top end of the column 1 being provided with an assembly part, and the arc-shaped plate 2 being connected to the assembly part.
[0033] In this technical solution, the style of column 1 is further provided. Column 1 may include multiple splicing sections 1014. Based on this, by setting the number of splicing sections 1014, the actual height of column 1 can be adjusted. Thus, the number of splicing sections 1014 can be selected based on the inner diameter of the wind turbine tower, which can further increase the applicability of the wind turbine tower wall concavity correction device.
[0034] like Figure 1 As shown, in one feasible implementation, the area of the bottom surface of the jack 3 is larger than the area of the arc-shaped plate 2. This configuration reduces the pressure of the jack 3 on the wind turbine tower wall when the concave correction device is installed inside the wind turbine tower, thus lowering the probability of damage to the wind turbine tower wall.
[0035] like Figure 1 As shown, in one feasible embodiment, the wind turbine tower wall concavity correction device further includes a buffer layer 5, which is disposed at the bottom of the bottom surface. This configuration, through the buffer layer 5, can further reduce the pressure of the jack 3 on the wind turbine tower wall, thereby further improving the reliability of maintenance. Example
[0036] like Figure 1 As shown, this device has been applied in an offshore wind power project undertaken by China Water Resources and Hydropower Engineering Bureau No. 4 (Yangjiang) Marine Engineering Equipment Co., Ltd. The application of this device effectively solved the problem of correcting the concave wall of the wind turbine tower.
