Description

Technical Field

[0001] This application relates to wind turbine tower technology, and more particularly to a device for spraying and cleaning the outer wall of a wind turbine tower. Background Technology

[0002] The wind turbine tower is a crucial component of wind power generation equipment. Wind turbine towers are typically composed of several sections, usually welded from high-strength low-alloy steel, with each section connected by flanges and high-strength bolts. To ensure the product quality of wind turbine towers, turbine manufacturers have imposed higher inspection requirements on the installation quality of internal accessories, the quality of paint corrosion protection, and the cleanliness of the tower, in order to improve the aesthetics of the wind turbine and enhance the brand image of the wind turbine tower manufacturer.

[0003] In related technologies, before leaving the factory, wind turbine towers need to undergo operations such as spraying patterns or cleaning surface debris on roller frames. The roller frames drive the wind turbine towers to rotate, making it convenient to spray patterns or clean surface debris at positions that are inaccessible to workers or equipment.

[0004] However, the wind turbine tower is coated with a protective paint layer before the pattern is painted or the surface is cleaned. When the roller frame drives the wind turbine tower to rotate, it can easily damage the protective paint layer, which seriously affects the corrosion protection quality of the wind turbine tower.

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. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components.

Therefore, they should not be construed as limitations on this application.

[0039] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0040] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0042] The wind turbine tower is an important component of wind power generation equipment, serving as the support structure for the wind turbine. As the connecting component between the wind turbine and the foundation ring, it transmits the weight of the hundreds of tons of wind turbine above. It is a crucial component for enabling functions such as wind turbine maintenance and power transmission. In the wind turbine generator set, it mainly plays a supporting role, while also absorbing unit vibrations to protect the wind turbine's safety and normal operation.

[0043] In recent years, the energy structure has been adjusted at an accelerated pace, energy transformation has been vigorously promoted, the energy structure has been optimized, and efforts have been made to achieve the goal of green development.

[0044] Among related technologies, onshore and offshore wind power have a wide coverage area, good resource endowment, and huge development potential. With the advent of the era of grid parity for onshore wind power, some manufacturers have established development goals of increasing single-unit capacity and lightweighting towers in order to reduce the cost of wind power and improve product profitability, so as to enhance corporate competitiveness and obtain the greatest market benefits.

[0045] One trend in wind turbine tower development is towards taller towers. Under high wind shear, increased height significantly increases wind speed. Solutions for tall tower technology include flexible steel towers (flexible towers), concrete towers (hybrid towers), truss structure towers, and cable-stayed structure towers. Compared to the uncertainty of construction quality in hybrid towers, flexible towers are favored by wind power manufacturers due to their significant economic advantages, short manufacturing cycle, and convenient decommissioning and dismantling. Secondly, there is a trend towards lightweight development, increasing single-unit capacity while reducing tower weight.

[0046] Wind turbine towers are typically divided into several sections, usually welded from high-strength low-alloy steel, with each section connected by flanges and high-strength bolts. To ensure the product quality of each wind turbine tower, the OEM has imposed higher inspection requirements on the installation quality of internal accessories, the quality of paint corrosion protection, and the cleanliness of the wind turbine tower. This is to improve the overall aesthetics of the wind turbine and enhance the brand reputation of the wind turbine manufacturer. Qualified wind turbine towers must be cleaned before leaving the factory to meet technical requirements and specifications.

[0047] When the wind turbine tower is large, such as a large-megawatt wind turbine tower, the main method for cleaning or painting the outer wall of the large-megawatt wind turbine tower is to rotate the tower. The large-megawatt wind turbine tower is placed on a roller frame, and the rollers of the roller frame are protected by a plastic film. The motor drives the rollers to rotate at a certain speed. Cleaning personnel use pressurized water guns to clean the large-megawatt wind turbine tower, or workers use inkjet printing equipment to paint on the tower.

[0048] Large-megawatt wind turbine towers are heavy, weighing approximately 120 tons per section. After anti-corrosion treatment, the outer wall of the tower is coated with a protective paint layer. However, as the tower rotates on the roller frame, the rollers exert strong pressure on the contact surface with the tower, squeezing the protective paint layer. In severe cases, this can cause cracking of the coating at the contact surface, resulting in the coating losing its protective ability. This seriously affects the anti-corrosion quality of the tower, greatly reducing its anti-corrosion lifespan, leading to increased maintenance costs and impacting the company's profitability and brand quality.

[0049] As mentioned above, the original cleaning and painting methods and equipment have shortcomings. They failed to consider that when the rollers of the roller frame come into contact with the wind turbine tower, they can cause varying degrees of damage or even destruction to the protective paint coating. This results in the coating losing its protective ability, severely impacting the tower's corrosion resistance and significantly reducing its service life. Consequently, it increases subsequent maintenance costs, affecting the company's profitability and brand quality. Furthermore, the roller frame's low rotation speed leads to low cleaning efficiency, wasting manpower and increasing costs.

[0050] Based on the aforementioned technical problems, this application provides a wind turbine tower outer wall painting and cleaning device. In this technical solution, the wind turbine tower outer wall painting and cleaning device includes a first support frame, a second support frame, and a connecting beam. The first and second support frames are spaced apart, forming a space between them for accommodating the tower. The top end of the first support frame is connected to the first end of the connecting beam, and the top end of the second support frame is connected to the second end of the connecting beam. At least one of the first and second support frames is equipped with an operating platform, which can be used to support workers for high-altitude operations. By setting an operating platform on at least one support frame, workers can perform high-altitude operations, such as painting patterns or cleaning surface debris, in a relatively safe and stable environment. This reduces the risks of high-altitude operations and improves the safety and convenience of the work. Since the tower does not need to rotate, damage to the protective paint coating on the tower surface is reduced. This helps maintain the corrosion resistance and aesthetic appearance of the wind turbine tower.

[0051] In addition, this device can be used in the painting of towers, providing convenient and reliable support and protection for the painting process, thereby improving the production efficiency of the painting.

[0052] It should be noted that, Figures 1 to 3 This diagram illustrates a simplified representation of the components in the wind turbine tower exterior painting and cleaning device. The specific structures of the remaining components in the wind turbine tower exterior painting and cleaning device are not limited to... Figures 1 to 3 of examples.

[0053] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, this application provides a wind turbine tower outer wall spraying and cleaning device, including a first support frame 100, a second support frame 200 and a connecting beam 300.

[0055] The first support frame 100 and the second support frame 200 are spaced apart, and a receiving space 10 for accommodating the tower 20 is formed between the first support frame 100 and the second support frame 200.

[0056] The top end of the first support frame 100 is connected to the first end of the connecting beam 300, and the top end of the second support frame 200 is connected to the second end of the connecting beam 300.

[0057] At least one of the first support frame 100 and the second support frame 200 is provided with an operating platform 400, which can be used to support workers.

[0058] In one specific implementation, the first support frame 100 includes two parallel first legs 110, and the second support frame 200 includes two parallel second legs 210. The ends of the first legs 110 facing away from the ground are connected to the first end of the connecting beam 300, and the ends of the second legs 210 facing away from the ground are connected to the second end of the connecting beam 300. Essentially, the first support frame 100, the second support frame 200, and the connecting beam 300 form a "gate"-shaped support. In this embodiment, the first support frame 100 and the second support frame 200 can also be plate-like structures to reduce the number of connection points with the connecting beam 300 and facilitate assembly. Of course, in this embodiment, the connecting beam 300 can also include connecting rods corresponding to the first legs 110 and the second legs 210, respectively. To improve structural stability, multiple connecting plates are provided between the two first legs 110, between the two second legs 210, and between the two connecting rods. This application does not restrict the specific implementation of the first support frame 100, the second support frame 200, and the connecting beam 300.

[0059] Here, the operating platform 400 can be a flat operating platform 400, a suspended platform 400, or an operating platform 400 fixed by suspension ropes. The operating platform 400 only needs to be large enough to accommodate the operator.

[0060] The operating platform 400 can be used to support workers for work at height. By installing the operating platform 400 on at least one of the first support frame 100 and the second support frame 200, workers can perform work at height in a relatively safe and stable environment, such as spraying patterns or cleaning surface debris. This reduces the risks of working at height and improves the safety and convenience of the operation. Since the tower 20 does not need to be rotated, damage to the protective paint coating on the surface of the tower 20 is reduced. This helps maintain the corrosion resistance and aesthetic appearance of the wind turbine tower 20.

[0061] In addition, workers can more easily stand on top of the tower when it is lying flat, which improves the efficiency of cleaning and printing operations.

[0062] In the application scenarios of the aforementioned wind turbine tower outer wall spraying and cleaning device, such as Figure 1As shown, the wind turbine tower 20 needs to lie flat on the ground to facilitate surface cleaning and painting operations by workers. The wind turbine tower 20 has a diameter of up to 6 meters and a relatively large weight per section. In this embodiment, the accommodating space 10 for housing the tower 20 needs to be at least 6 meters long along both its major and minor axes. Specifically, the vertical height H of the accommodating space is set between 8.5 meters and 9.5 meters, and the horizontal length is set between 6.5 meters and 7.5 meters. By setting the vertical length of the accommodating space to be greater than the horizontal length, it is convenient for the tower 20 to be placed on a support used only for fixing the tower 20, such as an existing roller frame, without the tower 20 needing to rotate. The accommodating space 10 extends through the tower 20 along its length to facilitate painting and cleaning operations on the tower 20 using the aforementioned wind turbine tower outer wall painting and cleaning device.

[0063] In one possible implementation, please continue to refer to Figures 1 to 3 As shown, both the first support frame 100 and the second support frame 200 are equipped with casters 500 at their bottom ends. The wind turbine tower outer wall painting and cleaning device can be moved by the casters 500, making it convenient for operators to push the wind turbine tower outer wall painting and cleaning device to a suitable working position.

[0064] In one possible implementation, the first support frame 100 is provided with an operating platform 400.

[0065] The operating platform 400 is positioned at the top of the first support frame 100 and extends toward the second support frame 200 to be close to the tower 20 located in the housing space 10. Positioning the operating platform 400 at the top of the first support frame 100 and extending toward the tower 20 allows operators to approach the tower 20 at a closer distance.

[0066] In the above embodiments, the operating platform 400 extends towards the second support frame 200, allowing operators to easily access various parts of the tower 20 without leaving the operating platform 400, especially areas requiring detailed printing or cleaning. This reduces the inconvenience caused by frequently moving the body or using additional tools to reach distant parts of the tower 20. The extension direction of the operating platform 400 towards the tower 20 effectively expands the operator's operating range. When printing patterns, whether using a spray gun or other printing tools, the surface of the tower 20 can be more comprehensively covered, including higher or more peripheral areas, such as the top of the tower 20's cross-section. For cleaning surface debris, it is also easier to clean all corners of the tower 20, ensuring thorough cleaning and improving the completeness and quality of the work. It avoids the need for frequent climbing or using climbing equipment due to distance, greatly shortening auxiliary time and allowing more time for actual printing and cleaning work, thus significantly improving overall work efficiency.

[0067] Furthermore, the operating platform 400 extends towards the tower 20, providing a more stable support for the workers. When performing work at heights, workers standing on the operating platform 400, which is relatively close to the tower 20, are more likely to keep their center of gravity within a stable range, reducing the risk of falling due to loss of balance.

[0068] In one possible implementation, the first support frame 100 is provided with an inclined portion 120.

[0069] The first end of the inclined portion 120 is located below the inclined portion 120, and the second end of the inclined portion 120 is close to the second support frame 200 relative to the first end of the inclined portion 120.

[0070] In the above embodiment, the inclined section 120 alters the structural form of the first support frame 100, resulting in a more rational distribution of the center of gravity for the entire wind turbine tower outer wall printing and cleaning device. When operators and printing or cleaning equipment are placed on the operating platform 400, the structure of the inclined section 120 guides gravity to be transmitted in a more stable direction. Compared to traditional vertical support frames, this design with the inclined section 120 reduces the risk of the device tipping over due to a shift in the center of gravity. Especially when the operating platform 400 carries heavy equipment or multiple operators, it ensures the device remains stable, providing a safe operating environment for printing and cleaning operations.

[0071] In this embodiment, the first support frame 100 may have a partial inclined portion 120, or the entire first support frame 100 may be configured with inclined portions 120. The inclined portion 120 increases the structural strength of the bottom of the first support frame 100. When faced with external forces, such as the lateral pressure of strong winds on the device and tower 20, the inclined portion 120 can provide additional anti-overturning moment like a diagonal brace. Compared with traditional vertical support structures, it can better resist overturning forces caused by wind or other external forces, enabling the entire device to remain stable under various complex working conditions, reducing the risk of collision with the tower 20 caused by device swaying, protecting the surface quality of the tower 20 and the safety of the device itself.

[0072] In one possible implementation, refer to Figure 3 As shown, both the first support frame 100 and the second support frame 200 are inclined, and the top of the first support frame 100 and the top of the second support frame 200 are inclined to the opposite side. This can further optimize the gravity distribution method, making the wind turbine tower outer wall spraying and cleaning device more stable, so that the whole device can remain stable under various complex working conditions, and reduce the risk of collision to the tower 20 caused by device shaking.

[0073] In specific implementation, the distance between the bottom ends of the first support frame 100 and the second support frame 200 is L1, and the length of the connecting beam 300 is L2. By setting L1 greater than L2, both the first support frame 100 and the second support frame 200 are inclined, and the top ends of the first support frame 100 and the second support frame 200 are inclined to opposite sides. The angles between the first support frame 100 and the connecting beam 300, and between the second support frame 200 and the connecting beam 300, are both set to C, with C set between 93 and 96 degrees. This allows the first support frame 100 and the second support frame 200 to bear more reasonable forces, enhancing stability.

[0074] In one possible implementation, such as Figure 1 As shown, the first support frame 100 is provided with a climbing structure 600, which is located on the outside of the inclined portion 120.

[0075] In the above embodiment, the climbing structure 600 is located outside the inclined portion 120, providing workers with a clearer and more defined climbing path. Workers can more easily and safely ascend and descend the operating platform 400 along the climbing structure 600. This helps reduce falls from heights due to climbing difficulties or mistakes, ensuring the personal safety of workers. When workers are performing painting or cleaning operations, adjustments may be needed at different heights and positions. The presence of the climbing structure 600 provides workers with more stable support points during movement, allowing them to better maintain their balance. When painting or cleaning the wind turbine tower 20, different parts of the tower 20 sometimes need to be treated. The climbing structure 600 allows workers to quickly adjust their position and expand their operating range according to actual needs.

[0076] In one possible implementation, the climbing structure 600 is tilted, and the top of the climbing structure 600 is connected to the operating platform 400.

[0077] The tilt angle of the climbing structure 600 relative to the vertical direction is greater than or equal to the tilt angle of the inclined section 120.

[0078] In the above embodiments, reference is made to Figure 1 As shown, the tilt angle of the climbing structure 600 relative to the vertical direction is A, and the tilt angle of the inclined part 120 is B, where A is greater than or equal to B.

[0079] In one possible implementation, when A is greater than B, the climbing structure 600 is inclined at a larger angle, making the direction of the gravitational force acting on the worker more favorable for climbing. Compared to a vertical or less inclined climbing structure 600, this reduces the gravitational resistance that the worker needs to overcome, making climbing easier and less strenuous. For example, when a worker climbs upwards along the inclined climbing structure 600, the gravitational force acting on the body is decomposed along the direction of the climbing structure 600, reducing the pressure perpendicular to the climbing structure 600, thereby reducing the risk of slipping and improving climbing safety. Furthermore, the larger inclination angle helps the worker maintain a stable center of gravity during climbing. When A equals B, the climbing structure 600 can be attached to the inclined portion 120, providing more support points and improving the stability of the climbing structure 600. In this embodiment, the climbing structure 600 can be a ladder or any climbing structure 600 in the relevant technical field; this application does not limit the specific structure of the climbing structure 600.

[0080] In one possible implementation, the climbing structure 600 is provided with a plurality of connectors 700.

[0081] Multiple connectors 700 are arranged vertically, and the climbing structure 600 can be connected to the first support frame 100 through the multiple connectors 700.

[0082] In the above embodiment, by providing multiple vertically arranged connectors 700, the connection force between the climbing structure 600 and the first support frame 100 is distributed to multiple points. During the worker's climbing process, the external forces generated by the weight of the human body and the climbing action on the climbing structure 600 are evenly distributed to each connector 700. This effectively reduces the stress borne by each connection point, lowers the risk of loosening, deformation, or even damage to the connectors 700 due to excessive local stress, and thus enhances the overall stability and safety of the climbing structure 600.

[0083] Of course, in one possible implementation, both the first support frame 100 and the second support frame 200 are equipped with climbing structures 600, which helps workers to perform cleaning and spraying operations from both sides of the tower 20 via the climbing structures 600.

[0084] In one possible implementation, the wind turbine tower outer wall painting and cleaning device further includes a cleaning component (not shown in the figure) and a painting component (not shown in the figure).

[0085] At least a portion of the cleaning assembly and at least a portion of the inkjet printing assembly are disposed on the connecting beam 300. In this embodiment, by disposing of at least a portion of the cleaning assembly and at least a portion of the inkjet printing assembly on the connecting beam 300, the operation of workers can be facilitated, thereby improving efficiency.

[0086] The cleaning assembly includes a cleaning tube that extends from the first support frame 100 through the connecting beam 300 to the second support frame 200.

[0087] The printing assembly includes a printing tube that extends from the first support frame 100 to the connecting beam 300.

[0088] In the above embodiment, the cleaning tube and the printing tube extend from the first support frame 100 through the connecting beam 300 to the second support frame 200. This prevents the printing tube and the cleaning tube from contacting the surface of the tower 20 during the operator's work, thus avoiding wear on the surface of the tower 20.

[0089] In one possible implementation, the second support frame 200 is provided with an operating platform 400.

[0090] The operating platform 400 is located at the top of the second support frame 200 and extends toward the first support frame 100 to be close to the tower 20 located in the accommodating space 10. By setting the operating platform 400 on the second support frame 200, the accommodation space for operators is increased, further facilitating cleaning and printing operations.

[0091] A protective cable 800 is installed between the first support frame 100 and the second support frame 200. The protective cable 800 is also installed between the two operating platforms 400, allowing workers to grip it for easy movement from the first support frame 100 to the second support frame 200, or for workers to move along the protective cable 800 using a safety rope, thus improving worker safety. Furthermore, the protective cable 800 helps maintain the relative position of the first support frame 100 and the second support frame 200, stabilizing the overall structural shape of the device.

[0092] The implementation principle of the wind turbine tower outer wall spraying and cleaning device according to an embodiment of this application is as follows: The device includes a first support frame 100, a second support frame 200, and a connecting beam 300. The first support frame 100 and the second support frame 200 are spaced apart, forming a receiving space 10 for accommodating the tower 20. The top end of the first support frame 100 is connected to the first end of the connecting beam 300, and the top end of the second support frame 200 is connected to the second end of the connecting beam 300. At least one of the first support frame 100 and the second support frame 200 is provided with an operating platform 400, which can be used to support workers for high-altitude operations. By setting the operating platform 400 on at least one support frame, workers can perform high-altitude operations, such as spraying patterns or cleaning surface debris, in a relatively safe and stable environment. This reduces the risk of high-altitude operations and improves the safety and convenience of the operation. Since the tower 20 does not need to be rotated, damage to the protective paint coating on the surface of the tower 20 is reduced. This helps maintain the corrosion resistance and aesthetic appearance of the wind turbine tower 20.
