Description

Technical Field

[0001] This utility model relates to the field of wind turbine processing, and in particular to a wind turbine blade spraying device. Background Technology

[0002] The statements in this section merely refer to the background technology related to this utility model and do not necessarily constitute prior art.

[0003] Thermal power generation is very harmful to the environment. In order to reduce environmental pollution, wind power generation has emerged. It uses a super-large blade that is driven by the wind at a certain height to generate electricity. Because the blade is too large and heavy, it is troublesome to install and disassemble. Therefore, painting is used to improve the service life of the blade, and a wind turbine blade painting device has been designed to facilitate the painting process.

[0004] Old-fashioned spraying equipment not only fails to ensure uniform spraying, but also cannot dry and adhere in time. This may cause the sprayed material to flow down to the bottom in a short time, resulting in an excessively thin coating that reduces the service life and also causes harm to the body. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wind turbine blade spraying device, the purpose of which is to achieve precise spraying while making the spraying of wind turbine blades more uniform and complete.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In one embodiment, multiple pulley support rods are fixedly installed on the side of the base plate, and a first pulley is installed at the bottom of each pulley support rod; a second pulley is slidably installed on the upper surface of the base plate, and the second pulley is rotatably connected to the bottom end of the column.

[0009] In one embodiment, a groove is formed on the upper surface of the base plate, and a second pulley is fixed in the groove. The side of the second pulley is rotatably connected to the bottom end of the column.

[0010] In one embodiment, a right-angle rod is fixedly provided on the side of the base plate, and a collection box is provided at one end of the right-angle rod.

[0011] In one embodiment, the device further includes a motor, a rack fixing plate, a rack, a sliding rod, and a gear; the motor is fixed to the base plate, the rack fixing plate is fixed to the bottom of the rear side of the hollow steel pipe, the sliding rod is fixed on the rack fixing plate, the rack is fixed on the sliding rod, and a gear is rotatably mounted on the upper surface of the motor, the gear meshing with the fixed rack.

[0012] In one embodiment, a drying device is provided on the second side plate. The drying device includes an air pump, an air distribution plate, and air pipes. Air pipes are fixedly provided on both sides of the air pump, and an air distribution plate is fixedly provided at one end of each air pipe. The air distribution plate includes an air outlet that passes through the second side plate and is located at the front end of the air distribution plate.

[0013] In one embodiment, the height adjustment assembly includes a first threaded rod support plate, a second threaded rod support plate, a threaded rod, a steel pipe, a first straight rod, and a second straight rod. The first threaded rod support plate and the second threaded rod support plate are disposed on the side of the hollow steel pipe. The lower surface of the first threaded rod support plate is rotatably connected to the bottom end of the threaded rod, and the top end of the threaded rod is rotatably connected to the second threaded rod support plate. A circular steel pipe is rotatably disposed on the outer circumference of the threaded rod, and a second straight rod is fixedly disposed on the outer circumference of the circular steel pipe. One end of the second straight rod is fixedly disposed on one end of the first straight rod, and the other end of the first straight rod is fixed to the lifting rod.

[0014] In one embodiment, a handle is fixedly provided at the bottom end of the threaded rod.

[0015] In one implementation, the column is made of square hollow steel pipe.

[0016] In one embodiment, a track plate is fixedly installed on the front side of the column, and a lifting structure is slidably installed on the track plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This invention can automatically spray paint in a left-right cycle. In the horizontal direction, the nozzle can be circulated and transported back and forth, which can make the spraying of the fan blades more uniform and complete. In the vertical direction, the height adjustment component drives the lifting rod to the appropriate position to achieve precise spraying, which further ensures the quality of the spraying work and prevents insufficient spraying thickness and uneven spraying that may be caused by excessive movement. It also reduces the workload of subsequent quality inspection and improves the efficiency of the spraying work.

[0019] 2. This invention incorporates components such as a motor, gears, and racks. The motor drives the gears to rotate, which in turn moves the racks that mesh with the gears. The racks then move the square hollow steel tube. Furthermore, pulleys are located below the square hollow steel tube, ensuring a more stable and smooth movement. A sliding rod prevents the square hollow steel tube from tilting during movement, thus enabling the device to automatically perform mobile painting.

[0020] 3. This invention incorporates components such as a threaded rod, a hand lever, and a circular steel pipe. By rotating the hand lever, the threaded rod rotates, which in turn moves the circular steel pipe up and down. When the circular steel pipe moves upward, it moves the first and second straight rods, causing the lifting rod to move as well. This increases the spraying height, allowing the device to adapt to different height conditions for spraying operations. Attached Figure Description

[0031] In the horizontal direction, the nozzle can be circulated and transported repeatedly, which can make the spraying of the fan blades more uniform and complete. In the vertical direction, the lifting rod is driven to the appropriate position by the height adjustment component to achieve precise spraying.

[0032] like Figure 1 The diagram shows the overall structure of the wind turbine blade spraying device.

A first pulley 1 is installed at the bottom of each pulley support rod 2. A second pulley 19 is slidably installed on the upper surface of the base plate 24. The side of the second pulley 19 is rotatably connected to the bottom end of the column 15.

[0033] In this embodiment, the column 15 is made of square hollow steel pipe.

[0034] Specifically, the side of the first pulley 1 is rotatably mounted on the bottom end of the pulley support rod 2 via a cylindrical rod, and the top end of the pulley support rod 2 is fixed to the side of the base plate 24; the side of the second pulley 19 is rotatably mounted on the bottom end of the column 15 via a cylindrical rod, and the column 15 can slide on the base plate 24 via the second pulley 19.

The vertical rod of the right-angle rod 25 is fixed to the side of the base plate 24, and a collection box 18 is fixedly installed at one end of the horizontal rod of the right-angle rod 25. The collection box 18 is used to collect the paint that has not yet dried after spraying and prevent it from falling onto the work surface and causing environmental pollution.

[0036] A motor 26 is fixedly installed at the bottom of the base plate 24. A toothed rod fixing plate 32 is installed at the bottom of the rear side of the column 15. A sliding rod 31 is fixed on the toothed rod fixing plate 32, and a toothed rod 23 is fixed on the sliding rod 31. A gear 21 is rotatably installed on the upper surface of the motor 26 through a cylindrical rod. The gear 21 meshes with the fixed toothed rod 23. Power is provided by the motor 26, so that the device can move and spray automatically.

[0037] A fixing block 28 is provided on the column, and the second side plate 12 is fixed to the fixing block 28. A spray box 7 is fixedly provided on the rear side of the second side plate 12, and a conveying pipe 10 is fixedly provided on the upper surface of the spray box 7. A lifting structure 29 is slidably provided at the front end of the column 15. A cavity is provided inside the lifting structure 29, and a nozzle 14 is provided on the surface. The spray box 7 and the cavity are connected through the conveying pipe 10. A first threaded rod support plate 5 and a second threaded rod support plate 9 are fixedly provided on the side of the column 15. The lower surface of the first threaded rod support plate 5 is rotatably connected to the bottom end of the threaded rod 6, and the top end of the threaded rod 6 is rotatably connected to the second threaded rod support plate 9. The outer circumference of the threaded rod 6 is... A circular steel pipe 27 is rotatably mounted, with one end of a second straight rod 17 fixedly connected to the outer circumference of the circular steel pipe 27. The other end of the second straight rod 17 is fixedly connected to one end of a first straight rod 16. A track plate 11 is fixedly mounted on the front side of the column, and a lifting structure 29 is slidably mounted on the track plate 11. The other end of the first straight rod 16 is fixedly connected to the lifting structure 29. A hand lever 4 is fixedly mounted at the bottom end of the threaded rod 6. By rotating the hand lever 4, the threaded rod 6 is rotated, causing the circular steel pipe 27 to move up and down, thereby moving the lifting structure 29. During spraying, under pressure, the spray material stored in the spray box is sprayed out from the nozzle through the cavity via a conveying hose.

[0038] The lifting rod allows for spraying at different heights, making the device adaptable to various situations. A drying device is also installed on the rear side of the second side plate 12. This drying device includes an air pump 20, an air distribution plate 13, and air pipes 22. Air pipes 22 are fixedly installed on both sides of the air pump 20, and an air distribution plate 13 is fixedly installed at one end of each air pipe 22. The air distribution plate 13 includes an air outlet 33 extending from the front of the second side plate 12. Airflow is provided by the air pump 20 and carried out by the air distribution plate 13, allowing the sprayed paint to dry more quickly. A first support plate 8 is fixedly installed on the front side of the second side plate 12, and a spring 30 is fixedly installed on the side of the first side plate 3. One end of the spring 30 is fixedly installed on the side of the first side plate 3, and the other end is fixed to the first support plate 8. When spraying is required, the first side plate 3 is pulled open. After completion, the first side plate 3 can be released and returned to its original position by the spring 30. The first side plate 3 effectively prevents the paint from spreading to areas other than the blades during spraying.

[0039] The working principle of this utility model is as follows:

[0040] To achieve the desired spraying height, open the first side plate 3, rotate the lever 4 to rotate the threaded rod 6, and move the circular steel pipe 27 upward. Then, the circular steel pipe 27 moves the first straight rod 16 and the second straight rod 17 upward, raising the lifting structure 29 to the appropriate position. Release the first side plate 3, and the spring 30 returns the first side plate 3 to its original position. Then, start the motor 26 and the spray box 7. The motor 26 drives the gear 21 to rotate, and the gear 21 moves the rack 23. When the rack 23 reaches one end, change the poles of the motor 26 so that the gear 21 rotates in the opposite direction. The entire nozzle 14 completes a cycle, resulting in a more uniform and complete spray. Start the air pump 20, which sprays air through the air pipe 22 and the air distribution plate 13 to increase the drying speed of the paint.
