Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The tower is the support structure of a wind turbine generator. It plays a crucial role in supporting the turbine and absorbing vibrations. Towers are typically hollow cylindrical structures with flanges at their ends. They are usually transported horizontally; however, the weight of the tower itself during transport can cause deformation of the flanges at the ends. This deformation can lead to misalignment between adjacent tower sections, affecting the safety of the connection between them.

[0022] In the traditional method, when adjacent tower sections are misaligned, the misalignment can be corrected by inserting locating pins. Specifically, the locating pins are inserted into the mating holes of the adjacent flanges and fixed in the flange holes by tapping or hammering. However, this method is time-consuming, labor-intensive, and difficult. The locating pins are difficult to remove after correction and can easily damage the tower flanges.

[0023] In view of this, this application provides a deformation adjustment device for a tower, which positions a positioning rod in the deformation area of ​​the flange structure, and then adjusts the tightness of the rope component through a tightening component. According to the deformation of the flange surface, the tightness of the tightening component is gradually adjusted until the flange surface is restored to the preset flatness. In this way, the deformation of the flange surface is corrected and the flatness of the flange surface is restored by positioning the positioning rod and adjusting the tightness of the locking adjustment component, thereby improving the connection safety between adjacent towers.

[0024] The following is combined with Figure 1 and Figure 2 Describes the deformation adjustment device for the tower of this application.

[0025] refer to Figure 1 and Figure 2 In this embodiment, the deformation adjustment device for the tower 10 has a flange structure 20 at one end, and the flange structure 20 has a plurality of flange connection holes 21 arranged along its circumference. The deformation adjustment device includes a positioning rod 100 and a tension adjustment assembly 200.

[0026] There are two positioning rods 100, which are respectively disposed in two flange connection holes 21 of the flange structure 20. The two flange connection holes 21 can be any two on the flange structure 20. Optionally, the two flange holes can also be two arranged opposite each other along the flange radial direction. At least one of the flange connection holes 21 where the positioning rod 100 is located is in the deformation area of ​​the flange structure 20.

[0027] The tension adjustment assembly 200 includes a rope component 210 and a tightening component 220. There are two rope components 210. The first end of each rope component 210 is fixedly connected to one of the positioning rods 100, and the second end is movably connected to the tightening component 220. The tightening component 220 is used to adjust the tension of the rope component 210. By controlling the tension of the rope component 210, fine adjustment of the flange surface deformation can be achieved. When the rope component 210 is tightened, an inward pulling force is generated, which acts on the positioning rod 100 and the flange surface, thereby correcting the flange surface deformation.

[0028] As can be seen, by positioning the positioning rod 100 in the deformation area of ​​the flange structure 20, and then adjusting the tightness of the rope 210 through the tightening member 220, the tightness of the tightening member 220 is gradually adjusted according to the deformation of the flange surface until the flange surface is restored to the preset flatness. In this way, by positioning the positioning rod 100 and adjusting the tightness of the locking adjustment component, the deformation of the flange surface is corrected, the flatness of the flange surface is restored, and the connection safety between adjacent tower cylinders 10 is improved.

[0029] For example, the tower deformation adjustment device of this embodiment can be provided in multiple sets. Multiple sets of devices can correct a wider range of flange surfaces, thereby improving the overall adjustment effect.

[0030] It should be noted that the deformation adjustment device of the tower in this embodiment can be used for the recovery operation after the flange surface is deformed, or it can be installed on the flange before the tower 10 is transported, so as to reduce or avoid flange surface deformation caused by transportation and reduce the damage that transportation may cause to the tower 10.

[0031] In some embodiments, combined with Figure 1 and Figure 2Two positioning rods 100 are respectively disposed in two radially opposite flange connection holes 21 along the flange structure 20. The radially opposite arrangement of the two positioning rods 100 forms a symmetrical support structure on the flange surface, which helps to resist the lateral forces that may be generated during the recovery process of the deformed area and prevents the flange surface from deforming or twisting. In addition, when the two positioning rods 100 are located in radially opposite positions, the arrangement of the positioning rods 100 and the tension adjustment assembly 200 makes the adjustment force more evenly distributed on the flange surface, improving the efficiency and accuracy of the correction.

[0032] In some embodiments, combined with Figure 1 The side wall of the positioning rod 100 is provided with a fixing groove 121 extending circumferentially along the positioning rod 100. The rope member 210 is sleeved in the fixing groove 121. The fixing groove 121 provides a limit for the rope. After the rope member 210 is sleeved in the fixing groove 121, it can fit closely to the positioning rod 100, making it less likely to slip or fall off, thus enhancing the stability of the connection.

[0033] In addition, the setting of the fixing groove 121 makes the installation and disassembly of the rope component 210 simple and quick. The operator can connect the rope component 210 and the positioning rod 100 by putting the rope component 210 into or taking out the fixing groove 121 without the need for other fixing devices or tools, which improves work efficiency and facilitates inspection and maintenance.

[0034] In some embodiments, combined with Figure 1 The positioning rod 100 includes a rod portion 110 and a head 120. The rod portion 110 passes through the flange connection hole 21 to achieve connection and fixation between the positioning rod 100 and the flange structure 20. The head 120 abuts against the end face of one axial end of the flange structure 20, and a fixing groove 121 is formed in the head 120. Thus, the arrangement of the rod portion 110 and the head 120 of the positioning rod 100 enhances the stability of the connection between the positioning rod 100 and the flange structure 20, and also ensures that the positioning rod 100 disperses stress when under force, avoiding local stress concentration.

[0035] In some embodiments, combined with Figure 1 and Figure 2 The rope component 210 includes a rope body 211 and a connector 212. The rope body 211 is connected to the positioning rod 100. One end of the connector 212 is connected to the rope body 211, and the other end is movably connected to the tightening component 220. This movable connection design allows the tightening component 220 to adjust the tension of the rope body 211 according to actual needs, thereby achieving deformation adjustment of the flange structure 20. Thus, through the cooperation of the rope body 211 and the connector 212, the adjustment force can be transmitted to the flange surface as needed. Specifically, the operator can control the tension of the rope body 211 by adjusting the position of the tightening member 220, thereby achieving fine adjustment of the flange surface deformation to adapt to different deformation conditions of the flange structure 20.

[0036] In some embodiments, combined with Figure 1 and Figure 2 The tightening member 220 has a tightening channel 221. The inner wall of the tightening channel 221 is provided with a connecting thread. The end of the connector 212 away from the rope body 211 is provided with a mating thread. The connector 212 is threadedly engaged with the tightening member 220 so that the connector 212 can move relative to the tightening member 220 along the axial direction of the tightening channel 221.

[0037] Specifically, the connector 212 and the tightening member 220 are connected via a threaded connection. Rotating the tightening member 220 controls the axial movement of the connector 212 within the tightening channel 221, allowing the adjustment device to adapt to different degrees and types of flange surface deformation, achieving both flexibility and stability in adjustment. Correspondingly, when adjusting the tension of the rope body 211, adjustment can be achieved simply by rotating either the tightening member 220 or the connector 212, simplifying operation and improving work efficiency.

[0038] In addition, the threaded fit has self-locking properties. When the tightening member 220 or the connecting member 212 is rotated to a certain position, the connecting member 212 will be locked in the tightening channel 221, which is not easy to loosen or fall off, thus ensuring the stability and reliability of the adjusting device during the adjustment process.

[0039] In some embodiments, the end of the rope body 211 facing the connector 212 is provided with a hanging ring 214, and the end of the connector 212 facing the rope body 211 is provided with a hook 213. The rope body 211 and the connector 212 are connected by hanging the hanging ring 214 through the hook 213.

[0040] The design of the hanging ring 214 on the rope body 211 and the hook 213 on the connector 212 makes the connection between the rope body 211 and the connector 212 simple and quick. The connection is completed simply by hooking the hook 213 into the hanging ring 214, without the need for additional tools or complicated procedures, making it highly operable. Furthermore, the connection method of the hanging ring 214 and the hook 213 facilitates the inspection of the connection points. Problems such as wear, loosening, or damage can be repaired or replaced promptly to ensure the normal operation of the adjustment device.

[0041] Optionally, the hook 213 and the loop 214 can be respectively provided on either the rope body 211 or the connector 212.

[0042] Optionally, the hanging ring 214 and the hook 213 can be set simultaneously, or either one can be set according to actual needs. For example, combining... Figure 1 and Figure 2 The rope member 210 on one side of the tightening member 220 may only have a hook 213, while the rope member on the other side may only have a hanging ring 214.

[0043] In some embodiments, at least one of the hook 213 and the loop 214 is rotatably connected to the rope member 210. Thus, when the connector 212 and the tightening member 220 rotate relative to each other for adjustment purposes, the rotatable connection design of at least one of the hook 213 and the loop 214 allows the rope body 211 to remain relatively stationary or undergo only slight compliant rotation, without experiencing significant twisting following the connector 212 and the tightening member 220. This protects the rope body 211 and prevents damage caused by excessive twisting.

[0044] In some embodiments, combined with Figure 1 and Figure 2 The rope body 211 includes a nylon rope. The nylon rope has good abrasion resistance and strength, can withstand large tensile forces, and facilitates the maintenance of tensile strength of the rope component 210 during adjustment.

[0045] In some embodiments, combined with Figure 1 The positioning rod 100 and the flange structure 20 are detachably connected. This detachable design ensures that the positioning rod 100 can be installed and removed as needed, improving the ease of installation of the tower deformation adjustment device. Furthermore, the detachable connection allows for quick replacement when the positioning rod 100 is damaged or requires repair. Additionally, the detachable connection allows for adjustment of the number and position of the positioning rods 100 to accommodate different deformation areas on the flange structure 20, according to actual needs.

[0046] In some embodiments, combined with Figure 1 The flange connection hole 21 is a threaded hole, and the positioning rod 100 is a threaded rod. The positioning rod 100 and the flange structure 20 are threadedly fitted. The threaded fit has high connection strength, ensuring that the positioning rod 100 will not loosen or fall off when bearing load. In addition, the threaded fit allows the positioning rod 100 to be screwed into the flange connection hole 21, realizing quick assembly between the positioning rod 100 and the flange connection hole 21, and improving work efficiency.

[0047] Optional, combined Figure 1A locking cap 130 is detachably connected to the end of the rod body away from the head 120. The locking cap 130 has a threaded groove and is threaded into the rod body. The threaded engagement between the locking cap 130 and the positioning rod 100 provides additional fastening force for the connection between the positioning rod 100 and the flange structure 20, ensuring that the positioning rod 100 is more stable when bearing load and reducing the risk of loosening or falling off.

[0048] This application provides a tower deformation adjustment device. A positioning rod 100 is positioned in the deformation area of ​​the flange structure 20. The tension of the rope component 210 is adjusted via a tightening component 220. The tension of the tightening component 220 is gradually adjusted according to the deformation of the flange surface until the flange surface returns to a preset flatness. Thus, by positioning the positioning rod 100 and adjusting the tension of the locking adjustment component, the deformation of the flange surface is corrected, and the flatness of the flange surface is restored. This improves the connection safety between adjacent tower sections 10, avoids the need for conventional methods of correcting by inserting positioning pins, and is simple to operate and less complex.
