Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices, and in particular relates to a grinding device for wind turbine blades. Background Technology

[0002] Wind turbine blades are typically made of composite materials, such as glass fiber reinforced resin and carbon fiber reinforced resin. After molding, these composite materials often have rough, uneven surfaces with excess adhesive and fiber protrusions. Therefore, a grinding process is needed to remove these surface defects and achieve a smooth and flat blade surface. However, in traditional grinding processes, grinding equipment is difficult to effectively remove dust, resulting in workers inhaling the generated dust over a long period, which can severely irritate and damage the human respiratory tract, potentially causing coughs, asthma, pulmonary fibrosis, and other diseases. At the same time, grinding also causes the dust to be highly dispersed, spreading throughout the working environment. This not only seriously affects the operator's vision, increasing the difficulty and danger of operation, but also causes the dust to easily spread to the surrounding area, polluting the surrounding environment. Therefore, a grinding device for wind turbine blades is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a grinding device for wind turbine blades. By incorporating a dust collection component, specifically, during the rotation of the shaft, a driving gear drives several driven gears to rotate together. The rotation of these driven gears, in turn, generates a powerful airflow through the rotation of several impellers, creating a negative pressure inside the dust collection hood. At this point, the dust generated during the grinding process is sucked into the dust collection hood. This solves the problem of traditional grinding equipment failing to effectively collect dust, leading to long-term inhalation of dust by workers, causing severe irritation and damage to the respiratory tract, potentially leading to coughs, asthma, pulmonary fibrosis, and other diseases. Furthermore, grinding causes dust to be highly dispersed, permeating the entire working environment. This not only severely affects the operator's vision, increasing the difficulty and danger of operation, but also causes dust to easily spread to surrounding areas, polluting the environment.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a grinding device for wind turbine blades, including a placement platform that provides a stable support foundation for the entire device, and further comprising: A grinding mechanism is disposed above the placement platform and is used to grind burrs on the surface of the blade. The placement platform has a drive robotic arm mounted on its back side.

[0005] Furthermore, the grinding mechanism includes a drive assembly, which is connected to the output end of the drive robotic arm and provides power output for the grinding operation; A dust collection component is connected to a drive component and is used to collect dust generated during the polishing operation. A filter assembly is disposed below the dust collection assembly and is used to filter the dust-containing air drawn in by the dust collection assembly. And a vibration component, which is connected to the filter component and is used to remove dust adhering to the surface of the filter in the filter component; The drive component includes a dust collection hood.

[0006] Furthermore, the top of the dust collection hood is connected to the output end of the driving robotic arm, a motor is installed on the inner wall of the dust collection hood, a fixed cylinder is provided below the motor, and a grinding disc is provided below the fixed cylinder.

[0007] Furthermore, a plurality of fixing brackets are welded to the outer ring of the fixing cylinder, and the side of the plurality of fixing brackets away from the fixing cylinder is welded to the inner wall of the dust collection hood; The fixed cylinder is rotatably connected to a rotating shaft, which passes through the fixed cylinder and extends to the top and bottom. The bottom output end of the motor is connected to the top of the rotating shaft through a coupling. The side of the rotating shaft away from the motor is welded to the top of the grinding disc.

[0008] Furthermore, the vacuuming assembly includes a drive gear, which is disposed above the fixed cylinder. Several driven gears are meshed on the outer surface of the drive gear. Rotary rods are welded inside each of the driven gears. The rotary rods pass through the fixed frame and extend to the bottom. Each of the fixed frames has an impeller at its bottom, the interior of each of the impellers is welded to the outer surface of the rotating rod, and the outer surface of each of the rotating rods is rotatably connected to the interior of the fixed frame.

[0009] Furthermore, the filter assembly includes a filter plate disposed below a plurality of sliders, and a drive bushing is provided on the inner ring of the filter plate, the inner ring of the drive bushing being welded to the outer surface of the rotating shaft; The drive shaft sleeve has a drive groove on its outer surface, and a slider is connected to the inner ring of the filter plate. The outer surface of the slider is slidably connected to the inner wall of the drive groove, and the inside of the drive groove is adapted to the outer surface of the slider.

[0010] Furthermore, the vibration assembly includes a number of fixed blocks, the sides of which are far apart from each other are welded to the inner wall of the dust collection hood, and the bottom of each of the fixed blocks is welded with a sliding rod, which penetrates the filter plate and extends to the bottom.

The bottom of several springs is connected to the top of the filter plate, and the side of several springs away from the filter plate is connected to the bottom of the fixing block.

[0011] This utility model has the following beneficial effects: 1. This utility model incorporates a dust collection component. Specifically, during the rotation of the shaft, a drive gear drives several driven gears to rotate together. As these driven gears rotate, several impellers generate a strong airflow, creating a negative pressure inside the dust collection hood. At this time, the dust generated during the grinding process is sucked into the dust collection hood, reducing the high dispersion of dust and its spread throughout the working environment. This reduces the impact on the operator's vision, lowers the difficulty and danger of the work, and also reduces the spread of dust into the surrounding environment, thus minimizing its impact.

[0012] 2. This utility model uses a vibration component, specifically a rotating shaft that drives the drive bushing to rotate, which in turn drives the drive slide groove to rotate. The slide block causes the filter plate to move up and down reciprocally. The filter plate slides on the slide rod and compresses or stretches the spring. After the spring is limited by the fixed block and stores energy, it pushes the filter plate to reset, thus increasing its vibration amplitude. This vibration filtration method reduces impurity blockage, maintains the permeability of the filter plate, and improves the effective dust collection effect during the grinding process.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5As shown, this utility model is a wind turbine blade grinding device, including a placement platform 111, which provides a stable support foundation for the entire device. It also includes a grinding mechanism 2, which is positioned above the placement platform 111 and is used to grind burrs on the blade surface. A drive robotic arm 112 is mounted on the back of the top of the placement platform 111. The grinding mechanism 2 includes a drive assembly 21, which is connected to the output end of the drive robotic arm 112 and provides power output for the grinding operation. A dust collection assembly 22 is connected to the drive assembly 21 and is used to collect dust generated during the grinding operation. A filter assembly 23 is also included. Below the suction assembly 22, a filter assembly 23 is used to filter the dust-containing air sucked up by the suction assembly 22. A vibration assembly 24 is connected to the filter assembly 23 and is used to remove dust adhering to the filter surface in the filter assembly 23. The drive assembly 21 includes a dust collection hood 211, the top of which is connected to the output end of the drive robotic arm 112. A motor 212 is installed on the inner wall of the dust collection hood 211. A fixed cylinder 214 is located below the motor 212, and a grinding disc 213 is located below the fixed cylinder 214. Several fixing brackets 215 are welded to the outer ring of the fixed cylinder 214, and the side of each fixing bracket 215 away from the fixed cylinder 214 is welded to the inner wall of the dust collection hood 211. A rotating shaft 216 is rotatably connected inside the fixed cylinder 214. The rotating shaft 216 passes through the fixed cylinder 214 and extends to the top and bottom. The bottom output end of the motor 212 is connected to the top of the rotating shaft 216 via a coupling. The side of the rotating shaft 216 away from the motor 212 is welded to the top of the grinding disc 213. The dust collection assembly 22 includes a drive gear 221, which is located above the fixed cylinder 214. Several driven gears 222 are meshed on the outer surface of the drive gear 221. A rotating rod 223 is welded inside each of the driven gears 222. The rotating rods 223 pass through the fixed frame 215 and extend to the bottom. Impellers 224 are provided at the bottom of each of the fixed frames 215. The interior of each impeller 224 is welded to the outer surface of the rotating rod 223. Several rotating rods 223 have their outer surfaces rotatably connected to the inside of the fixed frame 215. During the rotation of the rotating shaft 216, several driven gears 222 are driven to rotate together via the driving gear 221. The rotation of the driven gears 222 generates a strong airflow through the rotation of several impellers 224, creating a negative pressure inside the dust collection hood 211. At this time, dust generated during the grinding process of the grinding disc 213 is sucked into the dust collection hood 211, reducing the high dispersion of dust and its spread throughout the working environment. This reduces the impact on the operator's vision, lowers the difficulty and danger of the work, and also reduces the spread of dust into the surrounding environment, minimizing its impact. The filter assembly 23 includes a filter plate 231.A filter plate 231 is positioned below several sliders 234. A drive bushing 232 is located within the inner ring of the filter plate 231. The inner ring of the drive bushing 232 is welded to the outer surface of the rotating shaft 216. A drive groove 233 is formed on the outer surface of the drive bushing 232. Sliders 234 are connected to the inner ring of the filter plate 231. The outer surface of the sliders 234 is slidably connected to the inner wall of the drive groove 233. The interior of the drive groove 233 is adapted to the outer surface of the sliders 234. The vibration assembly 24 includes several fixed blocks 241. The sides of the fixed blocks 241 that are far apart from each other are welded to the inner wall of the dust collection hood 211. Slide rods 242 are welded to the bottom of each fixed block 241. The slide rods 242 penetrate the filter plate 231 and extend to the bottom. The outer surface of the slide rod 242 is slidably connected to the inside of the filter plate 231. Several slide rods 242 have springs 243 fitted on their outer surfaces. The bottom of several springs 243 is connected to the top of the filter plate 231, and the side of several springs 243 away from the filter plate 231 is connected to the bottom of the fixing block 241. The rotating shaft 216 drives the drive bushing 232 to rotate, which in turn drives the drive groove 233 to rotate. The slider 234 causes the filter plate 231 to move up and down reciprocally. The filter plate 231 slides on the slide rod 242, compressing or stretching the springs 243. After the springs 243 are limited and stored by the fixing block 241, they push the filter plate 231 back to its original position, increasing its vibration amplitude. This vibration filtration method reduces impurity clogging, maintains the permeability of the filter plate 231, and improves the effective dust collection effect during the polishing process.

[0019] A specific application of this embodiment is as follows: In use, the blade is first fixed to the top of the placement platform 111 by a lifting device. Then, the position of the dust collection hood 211 is adjusted according to the grinding position by a drive robotic arm 112. Then, the motor 212 is started to drive the grinding disc 213 to rotate via the rotating shaft 216. When the grinding disc 213 rotates, it grinds the surface of the blade. At the same time, the rotating shaft 216 rotates inside the fixed cylinder 214. Several fixing brackets 215 are welded to the surface of the fixed cylinder 214. The side of the fixing brackets 215 away from the fixed cylinder 214 is welded to the inner wall of the dust collection hood 211. At the same time, the top of the motor 212 is welded to the inner wall of the dust collection hood 211. Thus, the dust collection hood 211 provides a certain support for the motor 212. Meanwhile, during the rotation of the rotating shaft 216, the blade surface is ground. When the driving gear 221 rotates, it drives several driven gears 222 to rotate together. During the rotation of the driven gears 222, several impellers 224 are driven to rotate through the action of the rotating rod 223. At the same time, the rotating rod 223 rotates inside the fixed frame 215. During the rotation of the impellers 224, a strong airflow is generated, which creates a negative pressure state inside the dust collection hood 211. At this time, the dust generated during the grinding process of the grinding disc 213 is sucked into the dust collection hood 211, reducing the high dispersion of dust and its spread throughout the working environment. This reduces the impact on the operator's vision, reduces the difficulty and danger of the work, and also reduces the spread of dust into the surrounding environment, thus reducing the impact on the surrounding environment. Simultaneously, during the rotation of the rotating shaft 216, the drive shaft sleeve 232 will rotate, which in turn will drive the drive slide 233 to rotate as well. The rotation of the drive slide 233 will, through the action of the slider 234, cause the filter plate 231 to reciprocate up and down. During this movement, the inner edge of the filter plate 231 will slide on the outer surface of several slide rods 242. Simultaneously, the sliding of the filter plate 231 will compress or stretch several springs 243. These springs 243, limited by several fixing blocks 241, will store energy and cause the filter plate 231 to reset. Furthermore, the action of the springs 243 increases the vibration amplitude of the filter plate 231, achieving the effect of vibration while filtering. This reduces the likelihood of impurities in the dust clogging the filter plate 231, thereby improving its permeability and maintaining its performance, ultimately achieving effective dust extraction during the polishing process.
