Description

Technical Field

[0001] This invention relates to the field of wind power generation equipment, and more particularly to a coating device and coating method for wind power generation blades. Background Technology

[0002] In the production process of wind turbine blades, a coating needs to be applied. In existing technologies, spraying is a common method for applying the coating. For example, patent application number 201921368760.2 discloses a wind turbine blade coating device, including a housing. A horizontal plate is fixedly connected to the left side of the housing, and an electric telescopic rod is fixedly connected to the top of the horizontal plate. A connecting block is fixedly connected to the output end of the electric telescopic rod. A spraying plate is movably connected to the opposite side of the connecting block via a rotating rod. A first motor is fixedly connected to the front of the connecting block. This invention, through the cooperation of the electric telescopic rod, connecting block, spraying plate, first motor, vertical pipe, solenoid valve, and hose, achieves adjustable functionality. It allows adjustment of the height and angle of the spraying mechanism according to usage requirements, facilitating smooth spraying, improving the user experience of the wind turbine blade coating device, meeting current market demands, enhancing the practicality and usability of the wind turbine blade coating device, and solving the problem of previous wind turbine blade coating devices lacking adjustment functionality.

[0003] However, using spraying has two drawbacks. First, the sprayed paint is easily dispersed into the air, which can harm the health of nearby workers. Second, the spraying method results in a lot of paint not being sprayed onto the blades, leading to a certain amount of waste. Summary of the Invention

[0004] The purpose of this invention is to provide a coating device and coating method for wind turbine blades to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A coating device for wind turbine blades includes a coating box, two partitions fixedly disposed inside the coating box, and paint tanks disposed at the top and bottom of the coating box. The paint tanks are fixedly connected to the partitions by multiple connecting blocks. Multiple coating mechanisms are disposed on the side of the paint tank near the partitions, and the coating mechanisms penetrate through the partitions.

[0007] Preferably, a feeding pipe is fixedly installed through the coating tank, the feeding pipe passes through the coating tank and extends outside the coating tank, and a sealing cap is provided on the feeding pipe.

[0008] Preferably, the coating box has blade insertion slots on both the left and right sides, and a guide tube is provided in the blade insertion slot. Multiple springs are fixed on both the upper and lower sides of the guide tube. The end of the spring away from the guide tube is fixedly connected to the bracket. The bracket is fixedly connected to and communicates with the coating box.

[0009] Preferably, the coating mechanism includes a transfer box, which is fixedly connected to the paint box. Two support frames are fixedly provided on the side of the transfer box away from the paint box. The two support frames are arranged side by side. A slide is provided on the support frame. A rotating shaft is provided between the two support frames. The front and rear ends of the rotating shaft are respectively located in the slides of the two support frames. A limiting ring is fixedly sleeved on the end of the rotating shaft. A paint brush is rotatably sleeved on the rotating shaft.

[0010] Preferably, a second spring is provided inside the slide rail, with the lower end of the second spring fixedly connected to the rotating shaft and the upper end of the second spring fixedly connected to the slider.

[0011] Preferably, the transfer box has several through holes on the side away from the paint box.

[0012] Preferably, a guide cylinder is fixedly installed on the side of the transfer box away from the paint box, and a guide column is slidably connected inside the guide cylinder. One end of the guide column is fixedly connected to the slider, and the other end of the guide column is fixedly connected to one end of the adjusting tube. The other end of the adjusting tube passes through the paint box and extends into the interior of the paint box. Openings are provided at both ends of the adjusting tube.

[0013] Preferably, a limiting plate is fixed at one end of the regulating tube extending into the paint tank.

[0014] The beneficial effects of this invention are:

[0015] 1. This invention utilizes the shape of the blade to design a roller coating method. The blade is inserted into the device and then pulled out to complete the coating operation. This not only avoids waste of paint, but also effectively inhibits paint diffusion and protects the health of surrounding workers.

[0016] 2. During the blade insertion process, the regulating tube moves up and down intermittently, which allows some of the pigment in the paint box to enter the transfer box and then drip onto the paint brush through the through hole, automatically replenishing the paint brush and preventing insufficient paint on the paint brush.

However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0022] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1-3 As shown, a coating device for wind turbine blades includes a coating box 7 made of aluminum alloy. Two partitions 2 are fixedly installed inside the coating box 7, arranged vertically. Paint tanks 4 are located at both the top and bottom of the coating box 7, and are fixedly connected to the partitions 2 via multiple connecting blocks 3. The paint tanks 4 are used to store paint. Multiple coating mechanisms are located on the side of the paint tank 4 near the partitions 2, and these mechanisms penetrate the partitions 2. A feeding pipe 6 is fixedly installed through the paint tank 4, extending beyond the coating box 7. The feeding pipe 6 allows for the application of paint. Paint is added to the material box 4. A sealing cap 5 is installed on the feeding pipe 6. By connecting the sealing cap 5 to the feeding pipe 6, paint leakage from the paint box 4 can be prevented. The coating box 7 has blade insertion ports 24 on both the left and right sides. A guide tube 23 is installed in the blade insertion port 24. The blade 1 is inserted into the guide tube 23. Multiple springs 26 are fixed on both the upper and lower sides of the guide tube 23. The end of the spring 26 away from the guide tube 23 is fixed to the bracket 25. The bracket 25 is fixed to and connected to the paint box 4. By setting the springs 26, the blade 1 can shake to a certain extent when it is inserted into the device.

[0025] The coating mechanism includes a transfer box 12, which is fixedly connected to a paint tank 4. Two support frames 14 are fixedly mounted on the side of the transfer box 12 away from the paint tank 4. The support frames 14 are perpendicular to the transfer box 12 and are arranged side by side. A slide rail 15 is provided on the support frame 14. A rotating shaft 17 is provided between the two support frames 14. The front and rear ends of the rotating shaft 17 are respectively located in the slide rail 15 of the two support frames 14. A limiting ring 18 is fixedly sleeved on the end of the rotating shaft 17. A paint brush 19 is rotatably sleeved on the rotating shaft 17. A second spring 16 is provided in the slide rail 15. The lower end of the 6 is fixedly connected to the rotating shaft 17, and the upper end of the second spring 16 is fixedly connected to the slider 20. Several through holes 21 are opened on the side of the transfer box 12 away from the paint box 4. A guide cylinder 13 is fixedly connected through the side of the transfer box 12 away from the paint box 4. A guide post 22 is slidably connected inside the guide cylinder 13. One end of the guide post 22 is fixedly connected to the slider 20, and the other end of the guide post 22 is fixedly connected to one end of the adjusting tube 8. The other end of the adjusting tube 8 passes through the paint box 4 and extends into the paint box 4. Openings 11 are opened at both ends of the adjusting tube 8. A limiting plate 9 is fixedly provided at the end of the adjusting tube 8 that extends into the paint box 4.

[0026] Working principle: When in use, blade 1 is inserted into coating box 7 through guide tube 23, so that blade 1 comes into contact with paint brush 19. Continuously push blade 1 to move, so that paint brush 19 rolls paint on blade 1. During the movement of blade 1, because blade 1 is in contact with bracket 25 through guide tube 23 and spring 26, blade 1 will produce a certain amount of shaking during the movement. Blade 1 drives adjustment tube 8 to move back and forth through paint brush 19, rotating shaft 17, second spring 16, slider 20 and guide column 22.

[0027] For the transfer box 12 located at the top, when the opening 11 on the regulating pipe 8 near the paint box 4 moves into the paint box 4, the paint stored in the paint box 4 enters the regulating pipe 8 through the opening, and then is discharged into the transfer box 12 through the opening 11 on the other side. Then the paint drips onto the paint brush 19 through the through hole 21, replenishing the paint brush 19 with paint.

[0028] After a period of time, the device is flipped 180 degrees, so that the paint brush 19, which was originally located at the bottom, is flipped to the top, so that paint can drip onto the paint brush 19.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
