Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion treatment, and in particular to an anti-corrosion treatment device and method for offshore wind power equipment. Background Art

[0002] As an important form of clean energy, offshore wind power equipment is exposed to the marine environment for a long time and faces multiple corrosion factors such as seawater, salt spray, and moisture. In particular, the columnar components of metal structures such as towers, foundation columns, and support frames are susceptible to corrosion. In order to extend the service life of these components and ensure the safe and stable operation of wind power equipment, anti-corrosion spray treatment has become a necessary protective measure. The anti-corrosion spray device sprays the anti-corrosion paint evenly on the metal surface to form a dense protective layer, thereby effectively preventing corrosive substances such as salt spray, seawater and oxygen from directly contacting the metal surface. The structure of the anti-corrosion spray device includes a spray gun, a paint storage system, an air compression system, a paint delivery system, a control system, a protective cover, and a dust suction system. The spray gun is responsible for spraying the paint onto the target surface, and the control system adjusts the parameters during the spraying process to ensure that the coating is uniform and accurate. As disclosed in the authorization announcement number CN116371650B, an offshore wind power equipment anti-corrosion treatment device and a method of use include a liquid storage tank for storing anti-corrosion liquid, the liquid outlet end of the liquid storage tank is connected to a branching piece, and the branching piece is located outside the liquid storage tank; a reflux component, including a reflux cylinder fixed at the top of the liquid storage tank, a driving piece is rotatably connected in the reflux cylinder, one liquid outlet end of the branching piece is connected to the reflux cylinder and drives the driving piece to rotate; a conveying stirring piece is arranged below the driving piece, the fixed end of the conveying stirring piece is fixedly connected and connected to the liquid storage tank, and the movable end of the conveying stirring piece is transmission-connected and connected to the bottom end of the driving piece; a spraying component, including a spraying piece and a smearing piece, the other liquid outlet end of the branching piece is connected to the spraying piece, which can reduce the probability of sedimentation of the anti-corrosion liquid while being simple to operate, and can simultaneously spray and smear the wall surface. The existing offshore wind power equipment anti-corrosion treatment technology and device operation method are basically the same, that is, the paint is atomized and evenly covered on the metal surface by a high-pressure airflow, and after being solidified After quenching, a solid protective film is formed, which effectively delays the corrosion process. However, the above technical solution is mainly used to spray and apply anti-corrosion paint on the outer wall of columnar components such as towers and foundation columns in wind power equipment during use. In large-scale offshore wind power equipment, the height of the tower (composed of several tower sections) may reach tens of meters or even hundreds of meters. It is difficult for the spraying device to directly spray the inner wall surface of such a long tower section evenly, that is, during the spraying process, the nozzle of the spray gun needs to maintain a certain distance and angle to obtain the best coating effect. However, inside the hollow structure, due to the small space and complex angles, it is difficult for the spray gun to accurately control the coverage of the spraying, resulting in uneven coating of the paint in some areas or failure to achieve the ideal anti-corrosion effect. In the design of components such as towers and foundation columns, the diameter, length and curvature of the hollow structure often have large differences. This size change limits the adaptability of the spraying device and makes it difficult to adjust according to the characteristics of different components. Summary of the invention

After the externally threaded rod 1304 is screwed, the staff rotates the nut 1305, and the nut 1305 compresses the second spring 1306 to ensure the stability of the position of the externally threaded rod 1304, so that through precise distance control, excessive diffusion or uneven distribution of paint during spraying can be avoided, thereby ensuring the thickness and uniformity of the coating.

[0024] When the embodiment of the present application is in use, the operator first needs to adjust the height and position of the hanging frame 8, the elastic connection structure 9, the long L-shaped arm 10, the outer electric roller 11, the outer linear spraying module 12, the distance adjustment structure 13, the inner electric roller 14, and the inner linear spraying module 15 according to the size and weight of the wind power hollow cylindrical component to be treated with anti-corrosion spraying, to ensure that after the hollow cylindrical component is placed on the double-axis roller module 6, the outer electric roller 11 and the inner electric roller 14 can be firmly suspended and respectively located at the outer wall surface and the inner wall surface of the hollow cylindrical component. In this process, the pipe wall of the hollow cylindrical component needs to pass between the outer electric roller 11 and the inner electric roller 14 until the hollow cylindrical component is stably covered by the double-axis roller module 6. The roller module 6 supports; the outer electric roller 11, the outer linear spray module 12, the inner electric roller 14, the inner linear spray module 15 and the double-axis roller module 6 need to be checked one by one. The inspection items include whether the electric drive system is normal, whether the nozzle is unobstructed, whether the transmission mechanism is working properly, and whether the distance adjustment structure 13 can be accurately adjusted. In particular, it is necessary to ensure that the adjustment system of the electric roller and the spray module is fault-free to ensure the smooth progress of the spraying operation. Then the outer linear spray module 12 and the inner linear spray module 15 are connected to the external paint pumping end. At this time, according to the material and anti-corrosion requirements of the wind power hollow cylindrical components, select the appropriate anti-corrosion paint; after the device is ready, first start it through the PLC control panel 4 The double-axis roller module 6 makes the wind power hollow cylindrical component start to rotate. Through the self-rotation action, the surface of the hollow cylindrical component can evenly contact the paint spray sprayed by the spray module, especially the internal surface of the component. In this process, it is necessary to adjust the nozzle angle, spray distance and spray pressure of the spray module according to the actual situation to ensure that the paint can evenly cover every inch of the surface. Then the outer electric roller 11 and the inner electric roller 14 are started at the same time, and the two act on the outer wall and inner wall of the hollow cylindrical component respectively. The applicator is electrically driven to continuously and evenly apply the anti-corrosion paint to the surface. This synchronous operation ensures that the paint is evenly covered on both sides of the wall to avoid missing or uneven coating. During the spraying process, the X-axis primary belt The wheel electric traction module 2 is responsible for controlling the U-shaped frame 3, C-shaped bracket 5, hanging frame 8, spray module, and applicator to move along the longitudinal extension of the hollow cylindrical component until the spray module and applicator act on the entire hollow cylindrical component. At this time, it is necessary to adjust the speed and distance of the X-axis primary pulley electric traction module 2 in real time according to the specific situation of the component to ensure the uniform thickness of the paint layer and avoid missing spraying or re-coating; after spraying, the operator should check the adhesion, uniformity and integrity of the anti-corrosion coating, and observe whether the coating surface is smooth, without bubbles, peeling or falling off. After spraying, all equipment must be cleaned, especially the spray module and roller, to prevent paint residue from clogging the nozzle or affecting the performance of the device.
