Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment technology, specifically to a blade-type wind turbine tower rust removal device. Background Technology

[0002] Wind turbine towers are the support structures in wind turbine generators, primarily serving a supporting role while also absorbing vibrations. After long-term exposure to harsh environments such as wind, sun, snow, and rain, corrosion can occur. Specific causes include: old coatings exceeding their lifespan, resulting in powdering, peeling, blistering, loosening, and rusting; inadequate or absent surface preparation during initial painting, leading to coating peeling, loosening, and penetration of contaminants and moisture into the substrate; poor control during the painting process resulting in uneven paint film thickness and large areas of ineffective primer, failing to provide adequate corrosion protection; and damage to the coating caused by natural disasters (such as severe sandstorms). Therefore, regular rust removal, cleaning, maintenance, and upkeep of wind turbine towers and other foundation equipment are necessary.

[0003] Currently, rust removal on the surface of wind turbine towers is also done using robots instead of manual labor. However, existing rust removal equipment often has poor rust removal effect in actual use. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the rust removal equipment in the prior art has poor rust removal effect in actual use, and thus provide a blade-type wind turbine tower rust removal device.

[0005] To address the aforementioned technical problems, this utility model provides a flap-type wind turbine tower rust removal device, comprising: a wall-climbing robot body connected to a linear guide rail, wherein an adaptive adjustment component is provided on the linear guide rail; and a rust removal component disposed on the adaptive adjustment component, the rust removal component comprising a base plate and a driving component, a flap wheel, a mounting cover, a sliding mechanism, and a pressing mechanism, wherein the base plate is connected to the adaptive adjustment component, the sliding mechanism and the pressing mechanism are both disposed on the base plate, the driving component is disposed inside the mounting cover and connected to the sliding mechanism, the flap wheel is sleeved on the driving component, the driving component and the flap wheel penetrate the base plate, and the pressing mechanism is used to press the mounting cover.

[0006] Furthermore, the pressing mechanism includes an electric push rod and a thrust shaft, a pressure elastic element, and a guide plate. The electric push rod and the guide plate are both disposed on the base plate. The thrust shaft is disposed at one end of the electric push rod and passes through the guide plate. The pressure elastic element is sleeved on the thrust shaft and is used to press the mounting cover.

[0007] Furthermore, the pressure elastic element is a pressure spring.

[0008] Furthermore, the sliding assembly includes a fixed plate, a guide rail, and a slider. The fixed plate is vertically disposed on the base plate, the guide rail is disposed on the fixed plate, and the slider is connected to the mounting cover.

[0009] Furthermore, the base plate includes two U-shaped plates, which enclose a receiving space.

[0010] Furthermore, the drive unit is provided with an output shaft, and the flap wheel is sleeved on the output shaft.

[0011] Furthermore, the driving component is a motor.

[0012] Furthermore, it also includes multiple magnetic rollers, which are spaced apart at the bottom of the base plate. The magnetic rollers are used to support the base plate and attract the outer wall of the wind turbine tower to generate tension.

[0013] The technical solution of this utility model has the following advantages:

[0014] The present invention provides a flap-type wind turbine tower rust removal device, comprising: a wall-climbing robot body connected to a linear guide rail, wherein an adaptive adjustment component is provided on the linear guide rail; and a rust removal component disposed on the adaptive adjustment component, the rust removal component comprising a base plate and a driving component, a flap wheel, a sliding mechanism, and a pressing mechanism, wherein the base plate is connected to the adaptive adjustment component, the sliding mechanism and the pressing mechanism are both disposed on the base plate, the driving component is disposed on the sliding mechanism, the flap wheel is sleeved on the driving component, the driving component and the flap wheel penetrate the base plate, and the pressing mechanism is used to press the driving component and the flap wheel together.

[0015] By connecting a linear guide rail to the wall-climbing robot body and installing an adaptive adjustment component on the linear guide rail, which is connected to a rust removal component, the wall-climbing robot body drives the linear guide rail, the adaptive adjustment component, and the rust removal component to move on the wind turbine tower. Simultaneously, due to the linear guide rail, the position of the adaptive adjustment component can be adjusted to adapt to the curvature of the wind turbine tower's outer wall, ensuring the rust removal component is completely flush with the tower's outer wall. The base plate is connected to the adaptive adjustment component, allowing the sliding mechanism and the pressing mechanism to be mounted on it. In actual use, the pressing mechanism and the sliding mechanism work together; the pressing mechanism presses down on the mounting cover, causing the drive component and the flapper wheel to press against the wind turbine tower's outer wall, enabling the flapper wheel to perform rust removal. The flapper wheel's complete contact with the wind turbine tower's outer wall perfectly adapts to its curvature, achieving optimal rust removal results.

[0028] The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0029] Please see Figures 1 to 3 As shown, this utility model provides a flap-type wind turbine tower rust removal device, including: a wall-climbing robot body 1, which is connected to a linear guide rail 2, and an adaptive adjustment component 3 is provided on the linear guide rail 2; a rust removal component 4, which is provided on the adaptive adjustment component 3, the rust removal component 4 including a base plate 5, a driving component 6, a flap 7, a mounting cover 17, a sliding mechanism 8, and a pressing mechanism 9, the base plate 5 being connected to the adaptive adjustment component 3, the sliding mechanism 8 and the pressing mechanism 9 both being provided on the base plate 5, the driving component 6 being provided inside the mounting cover 17 and connected to the sliding mechanism 8, the flap 7 being sleeved on the driving component 6, the driving component 6 and the flap 7 penetrating the base plate 5, and the pressing mechanism 9 being used to press the mounting cover 17.

[0030] By connecting the linear guide rail 2 to the wall-climbing robot body 1, and installing an adaptive adjustment component 3 on the linear guide rail 2, which is connected to the rust removal component 4, the wall-climbing robot body 1 can move the linear guide rail 2, the adaptive adjustment component 3, and the rust removal component 4 on the wind turbine tower. Simultaneously, due to the linear guide rail 2, the position of the adaptive adjustment component 3 can be adjusted to adapt to the curvature of the wind turbine tower's outer wall, ensuring that the rust removal component 4 is completely flush with the outer wall of the wind turbine tower. The base plate 5 is connected to the adaptive adjustment component 3. Therefore, the sliding mechanism 8 and the pressing mechanism 9 can be installed on the base plate 5. In actual use, the pressing mechanism 9 and the sliding mechanism 8 work together to press the mounting cover 17 downward, so that the driving component 6 and the flap wheel 7 are pressed down together to the outer wall of the wind turbine tower. The flap wheel 7 can then be used for rust removal. The flap wheel 7 fits perfectly with the outer wall of the wind turbine tower and adapts perfectly to the curvature of the outer wall of the wind turbine tower, thus achieving the best rust removal effect.

[0031] The linear guide 2 and the adaptive adjustment component 3 are both existing technologies, so they will not be described in detail here.

[0032] In some optional embodiments, the pressing mechanism 9 includes an electric push rod 10 and a thrust shaft 11, a pressure elastic element 12, and a guide plate 13. The electric push rod 10 and the guide plate 13 are both disposed on the base plate 5. The thrust shaft 11 is disposed at one end of the electric push rod 10 and passes through the guide plate 13. The pressure elastic element 12 is sleeved on the thrust shaft 11 and is used to press the mounting cover 17.

[0033] With the electric push rod 10 and the thrust shaft 11 installed, and the thrust shaft 11 passing through the guide plate 13, the electric push rod 10 falls down, and the pressure elastic element 12 always applies pressure to the drive element 6, that is, it continuously tightens the mounting cover 17, that is, it presses the drive element 6, so that the flap 7 always fits against the outer wall of the wind turbine tower, and removes rust through the rotational friction of the flap 7.

[0034] In this embodiment, the pressure elastic element 12 is a pressure spring. By setting this pressure spring, the mounting cover 17 can be pressed tightly, thereby pressing the drive component, so that the flap 7 is always in contact with the outer wall of the wind turbine tower, thus ensuring the best rust removal effect.

[0035] Specifically, the sliding assembly includes a fixed plate 14, a guide rail 15, and a slider 16. The fixed plate 14 is vertically disposed on the base plate 5, the guide rail 15 is disposed on the fixed plate 14, and the slider 16 is connected to the mounting cover 17.

[0036] The guide rail 15 and the slider 16 enable the drive component 6 to move up and down relative to the fixed plate 14, that is, the mounting cover 17 and the drive component 6 can move up and down relative to the base plate 5.

[0037] In this embodiment, the pressure elastic element 12 is located between the guide plate 13 and the mounting cover 17. That is, the guide plate 13 and the mounting cover 17 limit the pressure elastic element 12, ensuring that it can only move in the axial direction of the thrust shaft 11. When the electric push rod 10 is lowered, the pressure elastic element 12 continuously applies pressure to the drive member 6, keeping the flapper wheel 7 in constant contact with the outer wall of the wind turbine tower, and removing rust through the rotational friction of the flapper wheel 7.

[0038] The base plate 5 includes two U-shaped plates 18, which together form a receiving space 19. This receiving space 19 is used to accommodate the drive component 6 and the flapper wheel 7, facilitating the fit of the flapper wheel 7 against the outer wall of the wind turbine tower.

[0039] Specifically, the driving component 6 is provided with an output shaft 20, and the flap wheel 7 is sleeved on the output shaft 20. The driving component 6 is a motor.

[0040] The flap-type wind turbine tower rust removal device also includes multiple magnetic rollers 21, which are spaced apart at the bottom of the base plate 5. The magnetic rollers 21 are used to support the base plate 5 and attract the outer wall of the wind turbine tower to generate tension.

[0041] In this embodiment, there are six magnetic rollers 21, which are spaced apart at the bottom of the base plate 5.

[0042] The specific working process of this blade-type wind turbine tower rust removal device:

[0043] The wall-climbing robot 1 moves on the wind turbine tower. Through the connection between the linear guide rail 2 and the adaptive adjustment component 3, the position of the adaptive adjustment component 3 can be adjusted. The adaptive adjustment component 3 then adapts to the curvature of the wind turbine tower's outer wall, ensuring that the rust removal component 4 is completely in contact with the outer wall. When the electric push rod 10 descends, the pressure elastic element 12 continuously applies pressure to the mounting cover 17 and the drive component 6. Under the action of the guide rail 15 and the slider 16, the pressure elastic element 12 continuously tightens the drive component 6, keeping the flap wheel 7 in constant contact with the outer wall of the wind turbine tower. Rust removal is achieved through the rotational friction of the flap wheel 7.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
