Description

Technical Field

[0001] This invention relates to the field of wind power equipment processing technology, specifically to an integrated cleaning device and method for processing wind turbine blades. Background Technology

[0002] Wind turbine blade processing and cleaning is a crucial step in blade manufacturing and operation and maintenance, spanning the entire lifecycle of production, installation, and operation. It is suitable for the industrial production of megawatt-class wind turbine blades and the regular maintenance scenarios of wind farms. During the processing stage, cleaning focuses on removing oil and dust from the blade mold and prepreg surface, using high-pressure spraying with specialized cleaning agents to ensure the bonding strength during blade casting. During the operation and maintenance stage, it addresses surface dust, insect remains, and salt spray deposits by using high-altitude cleaning equipment or drone cleaning technology to remove surface dirt and corrosion, restoring the blade's aerodynamic shape. The cleaning process requires strict control of water pressure and the pH of the cleaning agent to avoid damaging the fiberglass substrate and surface protective coating. However, existing wind turbine blade cleaning methods still present certain challenges. In the prior art, such as the wind turbine blade cleaning device and method with application number 202410256637.0, the technical solution is as follows: it includes two protective sleeves, which are respectively fixedly connected to two steel cables. A hanging plate is fixedly connected between the two protective sleeves. A fixed bending plate is fixedly connected to one side of the hanging plate. A wiping mechanism is set between the support plate and the fixed bending plate. The operator starts a servo motor, and the output shaft of the servo motor rotates back and forth, driving the two wiping strips to move back and forth left and right. Several squeezing rods can press the wiping strips to wipe the blade surface. However, the existing cleaning methods for wind turbine blades are simple, mostly using single high-pressure water washing or dry wiping, which makes it difficult to remove complex pollutants such as dust, oil, and release agents at the same time. The cleaning residue rate is high, and the cleaning range is limited. Complex parts such as the curved surface, leading edge, and trailing edge of the blade are prone to forming cleaning dead corners, and the cost of manual cleaning is high.

[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0004] To address the aforementioned issues, an innovative design was developed based on the existing wind turbine blade cleaning device. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated cleaning device and method for processing wind turbine blades, so as to solve the problems of the single cleaning method and incompatibility with the curved surface of the blades mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An integrated cleaning device for wind turbine blade processing includes a cleaning base, a support base fixedly mounted on the front side of the cleaning base, and several casters on the bottom of both the cleaning base and the support base. A control cabinet is mounted on top of the support base. A transmission roller is mounted on the upper surface of the cleaning base, and sliding grooves are provided on both the front and rear sides of the cleaning base. A cleaning robot is mounted on the rear side of the cleaning base, and the cleaning robot includes several mechanical transmission arms. A curved cover is provided at the output end of each mechanical transmission arm. Several cleaning brushes are mounted on the front side of the curved cover, and the curvature of the front side of the cleaning brushes is adapted to the wind turbine blade. The surface curvature of the plate is such that a cleaning agent support is provided on the upper front side of the cleaning base, and a fixed bracket is provided on the upper front side of the cleaning agent support. A first cleaning agent tank and a second cleaning agent tank are fixed inside the fixed bracket. The first cleaning agent tank is connected to a discharge pipe via a hose, and the discharge pipe is connected to a cleaning agent mixing tank. The second cleaning agent tank is connected to a cleaning agent tank via a hose. The bottoms of the first and second cleaning agent tanks are both connected to a discharge box, and the discharge box is provided with several discharge channels. Several piston rods are provided inside the discharge channels. The piston rods are evenly distributed on the rear side of the push plate.

[0007] Preferably, the cleaning base is provided with a filter screen inside, and a drain hole is provided on the side of the cleaning base.

[0008] By adopting the above technical solution, the filter screen inside the cleaning base is cleaned, the filtration rate of cleaning wastewater impurities is improved to avoid sewage blockage, the side drain hole quickly discharges wastewater, the cleaning efficiency is improved, the wastewater treatment time for a single cleaning is shortened, and it is suitable for continuous cleaning operations.

[0009] Preferably, a first servo motor is provided on the rear side of the cleaning base, and a second servo motor is provided on the front side of the cleaning base, and the output ends of the first servo motor and the second servo motor are both connected to threaded rods.

[0010] Using the above technical solution, the first and second servo motors on the front and rear sides of the cleaning base drive the threaded rod, improving the movement accuracy of the cleaning mechanism. The dual motors are independently controlled, which improves the cleaning range coverage efficiency compared to a single motor and is suitable for cleaning blades of different lengths.

[0011] Preferably, each of the threaded rods is threadedly connected to a slider, and the slider is slidably connected to the internal groove of the cleaning base. A first column is fixedly connected above the slider on the rear side of the cleaning base, and a cleaning robot is provided on the right side of the first column, forming a lifting structure.

[0012] Using the above technical solution, the outer slider of the threaded rod and the guide groove of the cleaning base improve the stability of the first column movement. The lifting structure of the cleaning robot on the right side of the first column improves the cleaning coverage of the upper and lower ends of the blades compared to a fixed height, and is suitable for blades of different diameters.

[0013] Preferably, the front side of the cleaning base has two sliders, and each slider is fixedly connected to a second column. A cleaning agent support is fixedly installed between the second columns. A cylinder is fixedly installed on the rear side of both the left and right sides of the cleaning agent support, and a movable frame is connected to the output end of the cylinder.

[0014] The above technical solution uses a double slider and a second column to support the cleaning agent support seat on the front side of the cleaning base, which improves the stability of the support. The cylinder drives the moving frame, which improves the efficiency of cleaning agent delivery compared to manual pushing, and is suitable for large-scale batch cleaning of blades.

[0015] Preferably, the lower part of the movable frame is slidably connected to the slide rod, and the slide rod is fixedly installed between the supports on the upper surface of the cleaning agent support seat. The push plate is fixedly welded to the middle of the movable frame, and the back-and-forth movement of the push plate drives the piston rod to be located inside the discharge channel of the discharge box to form a back-and-forth pushing structure.

[0016] By adopting the above technical solution, the sliding connection of the movable frame to the slide rod reduces the movement deviation of the push plate. The push plate drives the piston rod to push back and forth, which improves the discharge accuracy of the cleaning agent compared to gravity, and avoids waste of cleaning agent.

[0017] Preferably, the first cleaning agent tank is located on the front side above the discharge box, and the second cleaning agent tank is located on the rear side above the discharge box, and both the bottom of the first and second cleaning agent tanks and the top surface of the discharge box are provided with discharge pipes.

[0018] With the above technical solution, the first and second cleaning agent tanks are located above the discharge tank, which is a relatively dispersed layout. This shortens the cleaning agent delivery distance, improves delivery efficiency, and ensures that the bottom discharge pipe is precisely connected to the discharge tank, reducing leakage rate and maintaining a clean cleaning environment.

[0019] Preferably, the bottom of the discharge pipe is connected to a distribution pipe, and the distribution pipe below the first cleaning agent tank is connected to a first spray pipe, and the distribution pipe below the second cleaning agent tank is connected to a second spray pipe. The first spray pipe and the second spray pipe are arranged at equal intervals and alternately on the rear side of the discharge box.

[0020] Using the above technical solution, the feed pipe is connected to the distribution pipe and the first spray pipe and the second spray pipe are arranged in an alternating pattern, which increases the coverage area of ​​the cleaning agent. The two spray pipes spray cleaning agents of different pH values ​​simultaneously, which shortens the cleaning time and significantly improves the removal efficiency of complex stains compared to spraying in multiple stages.

[0021] Preferably, both the cleaning agent mixing tank and the cleaning agent tank are fixedly installed above the cleaning structure support plate, and a connecting pipe is provided between the cleaning agent mixing tank and the cleaning agent tank. The cleaning agent mixing tank is equipped with a stirring structure inside, and a pump is fixedly installed on the side of the cleaning agent support base and connected to the discharge pipe.

[0022] Using the above technical solution, the detergent mixing tank and the detergent tank are fixed to the cleaning structure support plate, which improves space utilization. The connecting pipe enables the two tanks to communicate with each other. Compared with independent storage, the detergent mixing flexibility is improved. The pump drives the discharge pipe to transport the detergent, which improves the stability of the conveying pressure.

[0023] An integrated cleaning method for wind turbine blade processing includes the following steps: detecting surface stains on the blade to be cleaned using a sensor structure, transmitting the collected stain information to a central processing system for analysis, generating a stain cleaning plan based on the stain information, controlling and mixing cleaning agents with different pH levels, and spraying them onto the surface of the wind turbine blade to achieve cleaning.

[0024] Using the above technical solution, the control cabinet automatically links the first servo motor, the second servo motor, the cylinder, and the cleaning robot based on the detected stains on the blade surface. This improves the cleaning automation rate, reduces labor costs, and allows different acid and alkalinity cleaning agents to be used for different stains. Compared with a single cleaning method, the cleaning residue rate is reduced, ensuring the quality of blade processing.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the integrated cleaning device and method for wind turbine blade processing, 1. Curved surface adaptation cleaning, completely eliminating dead corners in blade cleaning: Through the collaborative structure of mechanical transmission arm, curved mask, and arc-shaped cleaning brush, the robot achieves all-round contact cleaning of the complex curved surface of the blade. The mechanical transmission arm of the cleaning robot can flexibly adjust the angle, with an adjustment range of 0-180°, driving the curved mask to fit tightly against the blade surface. The cleaning brush on the front side of the curved mask adopts an arc design consistent with the curvature of the wind turbine blade surface, improving the blade curved surface contact rate. For areas that are difficult to cover by traditional cleaning methods, such as the leading edge, trailing edge, and variable cross-section curved surface of the blade, the cleaning brush can penetrate deep into the contact area for cleaning, reducing the cleaning dead corner area and adapting to the cleaning needs of blades of different lengths and diameters. 2. Precise spraying of cleaning agents with varying pH levels for efficient removal of complex contaminants: Utilizing a dual-tank cleaning agent system with precise volume control, the system enables on-demand supply and simultaneous spraying of cleaning agents with different pH levels. The first and second tanks can store acidic and alkaline cleaning agents respectively, suitable for various types of contaminants such as dust, oil, and release agents during blade processing. A cylinder-driven moving frame moves a pusher plate and piston rod to expel the cleaning agent from the tanks. Combined with a distribution pipe and staggered first and second spray pipes, precise volume control and uniform coverage of the cleaning agent are achieved, increasing the removal rate of complex contaminants, reducing cleaning residue, ensuring the surface cleanliness of the blades after processing, and meeting the bonding strength requirements of subsequent injection molding.

[0035] The curved mask 13 integrates multiple cleaning components and is compatible with various cleaning methods. Based on the "curved mask 13 and cleaning brush 14" in Example 1, the curved mask 13 is modularly modified: Curved mask 13 function expansion: Three sets of detachable installation interfaces are reserved on the front side of the curved mask 13, which are respectively adapted to the cleaning brush 14, the mini high-pressure spray gun and the silent fan. The interface adopts a quick-release buckle structure. The mini high-pressure spray gun is connected to the newly added high-pressure pump of the cleaning structure support plate 32 through a special hose 28. The spray pressure is adjustable and adapted to the cleaning of stubborn oil stains on the blades. The silent fan has a power of 500W and a wind speed of up to 15m / s. The air outlet is tilted at 15° to avoid direct airflow damaging the blade coating. It is suitable for quick drying of the blade surface after cleaning or pre-blowing of dust. Control linkage: A new "cleaning mode switching" module has been added to the control cabinet, which can simultaneously control the pressure of the mini high-pressure spray gun, the wind speed of the silent fan and the movement trajectory of the mechanical transmission arm 12, so as to realize the continuous operation of "pre-dust blowing-brushing-high pressure rinsing-drying". Example

[0036] Based on the "dual cleaning agent tank" in Example 1, a three-level cleaning agent supply system of "acidic, neutral and alkaline" is constructed, and the quantity control logic is optimized. The sensor structure set at the front end of the cleaning base 1 detects surface stains on the blades to be cleaned. The collected stain information is transmitted to the central processing system of the control cabinet 31 for analysis. According to the stain cleaning plan, the control cabinet 31 mixes cleaning agents with different pH levels in the cleaning agent mixing tank 33 and the cleaning agent tank 34, and sprays them on the surface of the wind turbine blades to achieve cleaning. Cleaning solution preparation: First cleaning agent box 26: Acidic cleaning agent pH2-3, citric acid solution, used to remove inorganic contaminants such as oxide layer and rust from the surface of leaves; Second cleaning agent box 27: Alkaline cleaning agent pH9-10, weak alkaline solution, used to remove mold release agents, heavy oil stains and other organic contaminants; The "acid-base neutralization" function of the detergent mixing tank 33: It can mix acidic and alkaline detergents in a 1:1 ratio to generate a neutral cleaning solution with a pH of 6.5-7.5, which is suitable for cleaning sensitive coated blades. Results: Improved removal rate of release agent residue; no corrosion marks after cleaning of sensitive coated blades; completely solves the problem of difficulty in both stain removal and coating protection in traditional cleaning.

[0037] Working principle: When using this invention, Equipment positioning and blade conveying stage: The device is moved to the blade cleaning station by the casters 3 at the bottom of the cleaning base 1 and the support base 2. The blade is conveyed to the cleaning area by the transmission roller 4. The first servo motor 7 and the second servo motor 8 drive the threaded rod 9, which in turn moves the first column 10 and the second column 15. The positions of the cleaning robot 11 and the cleaning agent support 16 are adjusted and aligned with the area to be cleaned on the blade. Cleaning agent preparation and spraying stage: According to the type of stains on the blades, the cylinder 17 is activated through the control cabinet, which pushes the moving frame 18 to move along the slide bar 19. The push plate 20 drives the piston rod 21 to squeeze the cleaning agent in the discharge box 22. The cleaning agents in the first cleaning agent box 26 and the second cleaning agent box 27 are sprayed onto the blade surface through the discharge pipe 25 and the distribution pipe 29, and alternately from the first spray pipe 23 and the second spray pipe 24. When it is necessary to mix the cleaning agents, the pump 36 sends the cleaning agent in the first cleaning agent box 26 into the cleaning agent mixing tank 33 through the hose 28 and the discharge pipe 37, and mixes it with the cleaning agent in the cleaning agent tank 34 before use. Automated cleaning stage of curved surface: The cleaning robot 11 is started, the mechanical transmission arm 12 drives the curved cover 13 to fit the curved surface of the blade, and the cleaning brush 14 rotates at high speed to brush the blade surface; the cleaning robot 11 can be raised and lowered along the first column 10, and move horizontally in conjunction with the threaded rod 9 to achieve cleaning of the entire surface of the blade without dead corners; the wastewater generated by brushing flows into the cleaning base 1, and after the impurities are filtered by the filter screen 5, it is discharged from the drain hole 6.
