Description

Technical Field

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

[0002] In wind power generation equipment, the wind turbine tower, as a crucial structural component supporting the nacelle and blades, is composed of multiple sections connected by flanges and high-strength bolts. Therefore, during long-term operation, internal connections such as flange joints, bolt tightness, and the presence of peeling internal anti-corrosion coatings require regular manual inspection and maintenance to ensure the integrity of the tower structure and operational safety. Without effective maintenance methods, loosening, corrosion, or fatigue damage at internal connections could potentially lead to equipment failure or even safety accidents. Therefore, regular maintenance of wind turbine towers is a critical step in ensuring the long-term stable operation of wind turbine units.

[0003] Chinese utility model patent CN206860378U discloses a tower clamping device for wind turbine tower maintenance, including a support frame with a fastening mechanism. The fastening mechanism includes a base, a drive shaft, and a mounting frame. The mounting frame is fixedly installed on the base, and the drive shaft is installed on the mounting frame. One end of the drive shaft is connected to a rotating motor via a reducer, and the other end is provided with a positioning disc. The positioning disc has multiple through holes, and each through hole contains a positioning block that slides with the positioning disc. Each positioning block has a connecting through hole. The support frame is provided with a guide rail, and the base slides with the guide rail. The base is also connected to a horizontal position adjustment mechanism. Multiple support platforms are provided between the two fastening mechanisms. The support platforms are installed on the support frame via a lifting mechanism. The upper surface of each support platform has an arc-shaped support surface. This device can stably fix each section of the tower and drive the tower to rotate stably, facilitating comprehensive inspection and preventing safety accidents.

[0004] However, this patented solution mainly focuses on the inspection of the outer wall of the tower and fails to provide a supporting structure that facilitates personnel to enter the tower for maintenance work. In particular, it is quite inconvenient when inspecting internal flange connections, bolt tightness, and damage to the internal protective layer. It is inconvenient for personnel to enter the inner wall of the wind turbine tower for maintenance work and to inspect the internal connections. There are also safety issues such as the wind turbine tower being prone to deflection when personnel are inspecting the inner wall. Utility Model Content

The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-4As shown in the present invention, a segmented wind turbine tower maintenance device includes a support platform 1, a plurality of support rotation components 2 are arranged on both sides of the support platform 1, a wind turbine tower 3 is carried on the plurality of support rotation components 2, limit components 4 are slidably connected on both sides of the support platform 1, a mobile platform 5 is arranged on the support platform 1, and maintenance components 55 are slidably connected on the mobile platform 5.

[0031] Several supporting rotation components 2 are symmetrically arranged on the left and right sides of the supporting platform 1 to support and rotate the wind turbine tower 3 for maintenance. Limiting components 4 can be adjusted according to the placement of the wind turbine tower 3, tightening the outer walls on both sides of the wind turbine tower 3 to prevent loosening. A movable platform 5 is installed inside the wind turbine tower 3 according to maintenance needs, and can slide along the axis of the wind turbine tower 3 to form a movable maintenance channel. After entering the wind turbine tower 3, it is assembled on-site and can carry maintenance personnel and tools. Maintenance components 55 are installed on the movable platform 5. This structure allows maintenance personnel to move axially along the inner wall of the wind turbine tower 3, enabling maintenance work to be carried out on the inner wall of the wind turbine tower 3, including maintenance of internal connections (such as flange connections and bolted connections). In actual use, the wind turbine tower 3... The wind turbine tower 3 is slowly rotated to the target angle by several supporting rotating components 2 and locked by limiting components 4. Then, the operator enters the wind turbine tower 3 through the mobile platform 5 and the maintenance component 55 to carry out the work, realizing the maintenance of the inner wall of the wind turbine tower 3. In addition, during the maintenance process, after the wind turbine tower 3 is rotated and adjusted to the appropriate position by several supporting rotating components 2, the limiting components 4 can limit and tighten the outer walls on both sides of the wind turbine tower 3 to prevent the wind turbine tower 3 from deflecting during the maintenance process. This makes it easy for personnel to enter the inner wall of the wind turbine tower 3 to carry out maintenance work and to carry out maintenance work on the internal connection points. The operation is convenient, and the wind turbine tower 3 is effectively limited when personnel are maintaining the inner wall, preventing it from deflecting and ensuring the safety of the maintenance.

[0032] In one embodiment, see Figure 1 and Figure 2 As shown, the supporting rotating assembly 2 includes a fixed base 21, which is set above the supporting platform 1. A drive motor 22 is set on one side of the upper part of the fixed base 21. A rotating roller 23 is fixedly connected to the output end of the drive motor 22. When the drive motor 22 starts, it directly drives the rotating roller 23 to rotate through its output shaft. The rotating roller 23 contacts the outer wall of the wind turbine tower 3. Through friction, the rotating roller 23 drives the wind turbine tower 3 to be inspected, which is attached to the upper surface of the rotating roller 23, to rotate slowly, supporting and driving the wind turbine tower 3 to rotate at a low speed around its axis to cooperate with the maintenance operation.

[0033] In one embodiment, see Figure 1 and Figure 3As shown, a mounting groove 211 is provided on the fixed base 21, and a rotating roller 23 is rotatably connected in the mounting groove 211. The mounting groove 211 is opened inside the fixed base 21 and has the structural function of accommodating and positioning the rotating roller 23. By providing the mounting groove 211 on the fixed base 21, the installation, maintenance and replacement of the rotating roller 23 can be facilitated, and a stable support foundation can be provided for the rotating roller 23.

[0034] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, a polyurethane layer is provided on the rotating roller 23. The polyurethane layer has a high coefficient of friction, which can enhance the friction of the contact surface when the rotating roller 23 contacts the outer wall of the wind turbine tower 3, prevent slippage caused by the weight of the wind turbine tower 3 or operational vibration, and effectively achieve stable support and precise positioning.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the limiting component 4 includes a limiting frame 41, which is slidably connected to the support platform 1. The limiting frame 41 is installed on the support platform 1 via a lead screw module (not shown in the figure), which is installed inside the support platform 1. (The lead screw module consists of a servo motor, a lead screw, and a lead screw nut. The servo motor drives the lead screw to rotate, which in turn drives the lead screw nut threaded onto the lead screw to rotate, thereby causing the limiting frame 41, which is fixedly connected to the lead screw nut, to move closer to the outer walls on both sides of the wind turbine tower 3.) The limiting frame 41 is provided with an annular mounting base 42, which is provided with several adjusting slide rails 43. Limiting sliders 44 are slidably connected to the several adjusting slide rails 43, and limiting blocks 45 are provided on the limiting sliders 44. The adjusting slide rails 43 and the limiting sliders 44 are connected with limiting blocks 45. The adjustable limiting mechanism is composed of slider 44. The position of the limiting slider 44 changes as it moves along the adjusting slide rail 43 (both the adjusting slide rail 43 and the limiting slider 44 are electric guide rails and slider structures, and each set of adjusting slide rail 43 and limiting slider 44 is composed of an electric guide rail and a ball screw transmission structure). The adjusting slide rail 43 and the limiting slider 44 are controlled by an external controller to move the limiting slider 44 on the adjusting slide rail 43, so that the limiting block 45 can move closer to or away from the outer walls on both sides of the wind turbine tower 3 to be limited, thereby adapting to the limiting requirements of different models of wind turbine tower 3. Multiple limiting blocks 45 are arranged on the annular mounting base 42 through multiple adjusting slide rails 43, which can achieve uniform limiting on the outer periphery of the wind turbine tower 3, avoid local stress concentration, and improve support stability.

[0036] In one embodiment, see Figure 1 and Figure 3As shown, the adjusting slide rail 43 is provided with a positioning hole 431, and the limiting slider 44 is provided with a mounting hole 441. Locking bolts are provided on the positioning hole 431 and the mounting hole 441. The positioning hole 431 on the adjusting slide rail 43 cooperates with the mounting hole 441 on the limiting slider 44, so that the position of the limiting slider 44 on the adjusting slide rail 43 can be adjusted according to the outer diameter of the wind turbine tower 3, thereby adapting to different models of wind turbine towers 3. By passing the locking bolt through the mounting hole 441 and the positioning hole 431 in sequence and tightening it, the limiting slider 44 can be accurately positioned and firmly locked, preventing it from slipping or loosening during equipment operation or maintenance, thereby enhancing the clamping force of the limiting block 45 on the wind turbine tower 3.

[0037] In one embodiment, see Figure 1 and Figure 3 As shown, the limit block 45 is provided with several rubber protrusions 451. The rubber protrusions 451 are made of elastic rubber. When the limit block 45 contacts the wind turbine tower 3, it can effectively absorb the impact force and vibration, avoid damage to the outer wall of the wind turbine tower 3 by hard contact, improve the safety of use, enhance the limiting effect, and prevent the wind turbine tower 3 from deviating, rotating or sliding during maintenance.

[0038] In one embodiment, see Figure 1 and Figure 4 As shown, the mobile platform 5 includes a mobile support frame 51, and a maintenance platform 52 is detachably connected between the two mobile support frames 51. An electric slide rail 53 is provided on the maintenance platform 52, and an electric slider 54 is slidably connected to the electric slide rail 53. A maintenance component 55 is provided on the electric slider 54. In use, the maintenance platform 52 is fixed between the two mobile support frames 51 to form the mobile platform 5. Then, the electric slide rail 53 (driven by a screw module) is activated, so that the electric slider 54 moves smoothly within the range of the electric slide rail 53. The control system can accurately position the components. Maintenance personnel select the appropriate maintenance component 55 according to the location of the tower or the defect location and install it on the electric slider 54 to perform maintenance operations on the target location.

[0039] In one embodiment, see Figure 1 and Figure 4As shown, the maintenance assembly 55 includes an installation platform 551, which is mounted on an electric slider 54. A lifting cylinder 552 is mounted on the installation platform 551, and an operating platform 553 is mounted on the lifting cylinder 552. The installation platform 551 provides the foundation support for the entire maintenance assembly 55, serving both installation and load-bearing functions. Mounted on the electric slider 54, it can move laterally with the operation of the electric slide rail 53, facilitating precise positioning of different parts by the maintenance device. The lifting cylinder 552, mounted on the installation platform 551, is used to vertically lift the operating platform 553. By controlling the extension and retraction stroke of the cylinder, the height of the operator or equipment can be adjusted to meet the operational needs of different height areas. The operating platform 553 provides a standing and working area for personnel and is equipped with safety features such as guardrails and anti-slip layers to ensure stability and operational safety during lifting.

[0040] In one embodiment, see Figure 1 and Figure 2 As shown, a toolbox rack 554 is provided on the operating platform 553. The toolbox rack 554 is designed to facilitate workers to easily access the tools they need during maintenance work, thereby improving maintenance efficiency and safety. The toolbox rack 554 can classify and fix commonly used tools such as wrenches, screwdrivers, power tools, and bolts, so that maintenance personnel do not need to frequently go up and down to retrieve and put away tools when working at heights or in confined spaces, thus improving the continuity of work and the convenience of operation.

[0041] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
