DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of the present application are described in detail below in conjunction with the drawings.

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

[0039] In the description of the embodiments of the present application, “plurality” means two or more, unless otherwise precisely and specifically specified.

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

[0041] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0042] The wind turbine tower is a crucial component of wind turbine equipment and serves as the mast for wind power generation. As the connecting member between the wind turbine and the foundation ring, it transmits the hundreds of tons of wind turbine weight above it. It is a crucial component for wind turbine maintenance and power transmission and transformation. It primarily supports the wind turbine and absorbs vibration, ensuring its safety and proper 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 boast extensive coverage, abundant resources, and enormous development potential. With the advent of onshore wind power parity, some manufacturers, in an effort to reduce wind power costs and improve product profitability, have established development goals of increasing unit capacity and lightweighting towers to enhance their competitiveness and maximize market benefits.

[0045] One of the development trends in wind turbine towers is taller towers. Under high shear conditions, increasing height significantly increases wind speed. Solutions for taller tower technology include flexible steel towers (flexible towers), concrete towers (hybrid towers), truss towers, and cable-stayed towers. Compared to the uncertainties in construction quality of hybrid towers, flexible towers are favored by wind turbine manufacturers due to their superior economic advantages, short manufacturing cycles, and easy decommissioning and disassembly. A second trend is lightweighting, reducing tower weight while increasing unit capacity.

[0046] Wind turbine towers are typically constructed in several sections, typically welded from high-strength low-alloy steel. Each section is connected by flanges and high-strength bolts. To ensure the quality of each wind turbine tower, wind turbine manufacturers impose stricter inspection requirements on the installation quality of internal accessories, paint corrosion protection, and tower cleanliness. This improves the overall appearance of the wind turbine and enhances 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 outer wall of the large-megawatt wind turbine tower is currently cleaned or sprayed mainly by rotating the tower. The large-megawatt wind turbine tower is placed on a roller frame, and the rollers of the roller frame are protected by plastic mulch. The motor drives the rollers to rotate at a certain speed. The cleaning staff uses a pressurized water gun to clean the large-megawatt wind turbine tower, or the staff uses spray painting equipment to spray the tower.

[0048] The weight of a single section of a large-megawatt wind turbine tower is large, about 120 tons. The outer wall of the tower has been coated with a paint protective coating after anti-corrosion treatment. The tower of a large-megawatt wind turbine rotates on a roller frame, and the contact surface between the roller and the tower generates a strong extrusion pressure, which squeezes the paint protective coating. In severe cases, the contact surface coating may crack, and the coating surface loses its protective ability, which has a serious impact on the anti-corrosion quality of the tower and greatly reduces the anti-corrosion life of the tower, resulting in an increase in subsequent maintenance costs, affecting the company's benefits and brand quality.

[0049] As mentioned above, the existing cleaning and painting methods and equipment were inadequate. They failed to consider that contact between the rollers and the wind turbine tower would cause varying degrees of damage or even destruction to the protective paint coating, resulting in a loss of protective coating and a serious impact on the tower's corrosion resistance. This significantly reduced the tower's corrosion lifespan, leading to increased maintenance costs and negatively impacting the company's profitability and brand quality. Furthermore, the rollers' slow rotation speed resulted in low cleaning efficiency, wasted labor, and inadvertently increased costs.

[0050] Based on the above technical problems, an embodiment of the present application provides a device for spraying and cleaning the outer wall of a wind turbine tower. In this technical solution, the device comprises a first support frame, a second support frame, and a connecting beam. The first support frame and the second support frame are spaced apart, and a storage space for accommodating the tower is formed between the first support frame and the second support frame. 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 support frame and the second support frame is provided with an operating platform that can be used to carry workers to facilitate high-altitude operations. By providing an operating platform on at least one of the support frames, workers can perform high-altitude operations, such as spraying 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 operations. Since there is no need to rotate the tower, 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 is used in the painting of towers, which can provide a convenient and reliable support and protection device for tower painting and improve the production efficiency of painting.

[0052] It should be noted that Figures 1 to 3 The schematic diagram of each component of the wind turbine tower outer wall spraying and cleaning device is shown. The specific structure of the remaining components of the wind turbine tower outer wall spraying and cleaning device is not limited to Figures 1 to 3 of examples.

[0053] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0054] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the present 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 from each other, and an accommodating 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 , and the operating platform 400 can be used to carry operating personnel.

[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. This is equivalent to the first support frame 100, the second support frame 200, and the connecting beam 300 forming a "door"-like support frame. In this embodiment of the present application, the first and second support frames 100 and 200 can also be plate-like structures to reduce the number of connection points with the connecting beam 300 and facilitate assembly. Of course, the connecting beam 300 in this embodiment of the present application can also include connecting rods corresponding to the first and second legs 110, 210, respectively. To improve structural stability, multiple connecting plates are provided between the two first legs 110, multiple connecting plates are provided between the two second legs 210, and multiple connecting plates are provided between the two connecting rods. This application does not limit the specific implementation forms 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-plate operating platform 400, a hanging basket-shaped operating platform 400, or an operating platform 400 fixed by a hanging rope. The operating platform 400 only needs to be able to accommodate the operator to work.

[0060] The operating platform 400 can be used to carry workers for elevated work. 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 elevated work, such as spray painting or cleaning surface debris, in a relatively safe and stable environment. This reduces the risks of working at height and improves operational safety and convenience. Since the tower 20 does not need to rotate, damage to the protective paint coating on the tower 20 surface is reduced. This helps maintain the corrosion resistance and aesthetic appearance of the wind turbine tower 20.

[0061] In addition, the operator can more conveniently stand on the top of the tower 20 when it is lying flat, thereby improving the efficiency of the cleaning and spray painting operations.

[0062] In the application scenario of the above-mentioned wind turbine tower outer wall spraying and cleaning device, such as Figure 1As shown in , the wind turbine tower 20 needs to lie flat on the ground to facilitate the operators to carry out surface cleaning and spray painting operations. The diameter of the wind turbine tower 20 can reach 6 meters, and the weight of a single section is relatively large. In the embodiment of the present application, the accommodating space 10 for accommodating the tower 20 needs to be at least greater than 6 meters on both the major axis and the minor axis. Specifically, the height H of the accommodating space in the vertical direction is set to between 8.5 meters and 9.5 meters, and the length of the accommodating space in the horizontal direction is set to between 6.5 meters and 7.5 meters. By setting the length of the accommodating space in the vertical direction to be greater than the length of the accommodating space in the horizontal direction, it is possible to facilitate the tower 20 to be placed on a bracket that is only used to fix the tower 20, such as an existing roller frame, but the tower 20 does not need to rotate. The tower 20 is provided with the accommodating space 10 in its length direction, so that the operators can use the above-mentioned wind turbine tower outer wall spray painting and cleaning device to spray paint and clean the tower 20.

[0063] In one possible implementation, please refer to Figures 1 to 3 As shown, the bottom ends of the first support frame 100 and the second support frame 200 are both provided with universal wheels 500, and the wind turbine tower outer wall spraying and cleaning device can be moved through the universal wheels 500, making it convenient for operators to push the wind turbine tower outer wall spraying and cleaning device to a suitable working position.

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

[0065] The operating platform 400 is disposed 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 accommodation space 10. The operating platform 400 is disposed at the top of the first support frame 100 and extends toward the tower 20, allowing operators to get closer to the tower 20.

[0066] In the above-described embodiment, the operating platform 400 in the present application extends toward the second support frame 200, allowing operators to easily access various parts of the tower 20 without leaving the operating platform 400, especially those areas that require detailed painting or cleaning. This reduces the inconvenience caused by frequent body movements or the use of additional tools to reach distant parts of the tower 20. In the present application, the operating platform 400 extends toward the tower 20, effectively expanding the operator's operating range. When spraying patterns, whether using a spray gun or other painting tools, the surface of the tower 20 can be more comprehensively covered, including some higher or more marginal locations, such as the top of the tower 20 cross-section. When cleaning surface debris, every corner of the tower 20 can be cleaned more conveniently, ensuring that there are no blind spots, thereby improving the integrity and quality of the work. This avoids the need for frequent climbing up and down or using climbing equipment due to long distances, thereby greatly reducing auxiliary time and allowing more time to be spent on actual spraying and cleaning work, significantly improving overall work efficiency.

[0067] Furthermore, the operating platform 400 extends toward the tower 20, providing a more stable support for workers. When working at height, workers standing on the operating platform 400, relatively close to the tower 20, can more easily maintain their center of gravity within a stable range, reducing the risk of falling due to imbalance.

[0068] In a 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 . Relative to the first end of the inclined portion 120 , the second end of the inclined portion 120 is close to the second support frame 200 .

[0070] In the above embodiment, the inclined portion 120 changes the structural form of the first support frame 100, making the center of gravity distribution of the entire wind turbine tower outer wall spraying and cleaning device more reasonable. When the operator and the spraying or cleaning equipment are placed on the operating platform 400, the structure of the inclined portion 120 can guide gravity to be transmitted in a direction that is more conducive to stability. Compared with the traditional vertical structure support frame, this design with the inclined portion 120 can reduce the risk of the device tipping over due to the shift of the center of gravity, especially when the operating platform 400 carries heavier equipment or multiple operators, it can ensure that the device remains stable, providing a safe operating environment for spraying and cleaning operations.

[0071] In the embodiment of the present application, the first support frame 100 may be provided with an inclined portion 120 in a partial area, or the entire first support frame 100 may be provided with an inclined portion 120. The inclined portion 120 increases the structural strength of the bottom of the first support frame 100. When facing external forces, such as the lateral pressure of strong winds on the device and the 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 the overturning force caused by wind or other external forces, so that the entire device can remain stable under various complex working conditions, reduce the risk of collision with the tower 20 caused by the shaking of the device, and protect the quality of the surface of the tower 20 and the safety of the device itself.

[0072] In one possible implementation, refer to Figure 3 As shown, the first support frame 100 and the second support frame 200 are both tilted, and the top of the first support frame 100 and the top of the second support frame 200 are both tilted toward 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 entire device can remain stable under various complex working conditions, reducing the risk of collision with the tower 20 caused by shaking of the device.

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

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

[0075] In the above embodiment, the climbing structure 600 is located outside the inclined portion 120, providing the operator with a clearer and more defined climbing path. The operator can move up and down the operating platform 400 more conveniently and safely along the climbing structure 600. This helps to reduce accidents of falling from heights due to climbing difficulties or mistakes, and ensures the personal safety of the operators. When the operator is performing spray painting or cleaning operations, it may be necessary to make adjustments at different heights and positions. The presence of the climbing structure 600 provides the operator with a more stable support point during movement, allowing the operator to better maintain body balance. When spray painting or cleaning the wind turbine tower 20, it is sometimes necessary to process different parts of the tower 20. The climbing structure 600 allows the operator to quickly adjust his position according to actual needs and expand the operating range.

[0076] In a possible implementation, the climbing structure 600 is arranged at an angle, and the top of the climbing structure 600 is connected to the operating platform 400 .

[0077] With respect to the vertical direction, the inclination angle of the climbing structure 600 is greater than or equal to the inclination angle of the inclined portion 120 .

[0078] In the above embodiment, referring to Figure 1 As shown, relative to the vertical direction, the inclination angle of the climbing structure 600 is A, the inclination angle of the inclined portion 120 is B, and A is greater than or equal to B.

[0079] In one possible embodiment, when A is greater than B, the climbing structure 600 is tilted at a larger angle, so that the component of gravity acting on the worker during the climbing process is more conducive to climbing. Compared to a vertical climbing structure 600 or a climbing structure with a smaller tilt angle, this reduces the gravitational resistance that the worker must overcome during climbing, making climbing easier and more labor-saving. For example, when a worker climbs upward along the tilted climbing structure 600, the component of gravity acting on the worker's body is dispersed 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 tilt angle helps the worker maintain a stable center of gravity during the climbing process. When A is equal to B, the climbing structure 600 can be attached to the inclined portion 120, providing the climbing structure 600 with more support points and improving its stability. In the embodiments of the present application, the climbing structure 600 can be a ladder or a climbing structure 600 known in the relevant art. This application does not limit the specific structure of the climbing structure 600.

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

[0081] The plurality of connectors 700 are arranged in a vertical direction, and the climbing structure 600 can be connected to the first support frame 100 via the plurality of 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 dispersed across multiple points. During the climbing process, the external forces exerted on the climbing structure 600 by the operator's weight and the climbing motion are evenly distributed across each connector 700. This effectively reduces the stress on each connection point and mitigates the risk of loosening, deformation, or even damage to the connectors 700 due to excessive local stress, thereby enhancing the overall stability and safety of the climbing structure 600.

[0083] Of course, in a possible implementation, both the first support frame 100 and the second support frame 200 are provided with a climbing structure 600 , which helps workers to perform cleaning and spray painting operations from both sides of the tower 20 through the climbing structure 600 .

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

[0085] At least a portion of the cleaning component is disposed on the connecting beam 300, and at least a portion of the inkjet printing component is disposed on the connecting beam 300. In the embodiment of the present application, by disposing at least a portion of the cleaning component on the connecting beam 300 and at least a portion of the inkjet printing component on the connecting beam 300, it is possible to facilitate the operation of the operator, thereby improving efficiency.

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

[0087] The inkjet printing assembly includes an inkjet printing tube, which extends from the first support frame 100 to the connecting beam 300 .

[0088] In the above embodiment, the cleaning pipe and the inkjet printer pipe extend from the first support frame 100 to the second support frame 200 through the connecting beam 300. This prevents the inkjet printer pipe and the cleaning pipe from contacting the surface of the tower 20 during operation, thereby avoiding wear on the surface of the tower 20.

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

[0090] An operating platform 400 is mounted on top of the second support frame 200 and extends toward the first support frame 100, bringing it closer to the tower 20 within the receiving space 10. The installation of the operating platform 400 on the second support frame 200 increases the space available for operators, further facilitating cleaning and inkjet 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. Workers can grasp the protective cable 800 to facilitate movement from the first support frame 100 to the second support frame 200. Alternatively, workers can use a protective rope to move along the protective cable 800, thereby improving worker safety. Furthermore, the presence of the protective cable 800 helps maintain the relative position between the first support frame 100 and the second support frame 200, stabilizing the overall structural shape of the device.

[0092] The present embodiment of the present invention provides a wind turbine tower exterior wall painting and cleaning device. The device comprises 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, while 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 providing the operating platform 400 on at least one of the support frames, 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 safety and convenience. Since the tower 20 does not need to rotate, damage to the protective paint coating on the tower 20 surface is reduced. This helps to maintain the anti-corrosion quality and beautiful appearance of the wind turbine tower 20.
