Furthermore, dust adhering to equipment can affect its normal operation and service life.

[0003] Currently, existing dust control measures for wind turbine blade cutting are relatively simple, typically involving only basic shielding, which is ineffective and allows dust to still escape in large quantities.

[0028] Reference Figures 1 to 4This invention relates to a dust prevention device for wind turbine blade cutting, as described in some embodiments of the present invention. The device prevents dust from escaping during the cutting process of wind turbine blades 7 by the wind turbine blade cutting device 6. It includes a support base 1, a drive mechanism 2, a curtain assembly 3, a telescopic frame mechanism 4, and a dust filtration and recovery mechanism 5. The telescopic frame mechanism 4 is mounted on the support base 1 and can move horizontally along the support base 1. The drive mechanism 2 is mounted on the support base 1 and drives the telescopic frame mechanism 4. The curtain assembly 3 includes a front curtain 31, a middle curtain 32, and a rear curtain 33. These three curtains work together to prevent dust from escaping during the cutting of the wind turbine blades 7. The front curtain 31 is mounted on the wind turbine blade cutting device 6, the middle curtain 32 is mounted on the telescopic frame mechanism 4 and is connected to the front curtain 31, and the rear curtain 33 is mounted at the end of the middle curtain 32 furthest from the front curtain 31. The dust filtration and recovery mechanism 5 is used to recover and filter the dust generated during the cutting of the wind turbine blades 7.

[0029] The support base 1 is formed by welding rectangular tubes, with a protective paint finish and rust prevention treatment. The mounting reference surface has an anti-rust coating, while the non-installation surfaces are painted. The carbon steel structural components are blackened. The dust filtration and recovery mechanism 5 is used to recover and filter the dust generated during the cutting of the wind turbine blades 7. It can utilize existing dust filtration and recovery equipment, such as a recovery box with a filter and fan. The fan's suction port is located within the space enclosed by the curtain assembly 3, and the fan draws the dust into the recovery box for filtration and recovery. Under the suction of the dust filter, a negative pressure is maintained within the space enclosed by the curtain assembly 3, reducing dust leakage. Furthermore, the rear curtain 33 can be manually operated, while the front curtain 31 can be electrically operated.

[0030] Understandably, this dustproof device for wind turbine blade cutting, by setting up a curtain assembly 3, including a front curtain 31, a middle curtain 32, and a rear curtain 33, can effectively block the dust generated during the cutting process and prevent dust from spilling into the working environment. The telescopic frame mechanism 4 can move horizontally along the supporting base 1, and under the drive of the drive mechanism 2, it can be flexibly adjusted according to the length of the wind turbine blade 7 and the cutting position, improving the applicability of the device. The dust filtration and recovery mechanism 5 can recover and filter the dust generated during cutting, which not only reduces dust pollution but also allows for dust recycling, saving resources.

[0031] like Figure 1As shown, the telescopic frame mechanism 4 includes multiple column assemblies 41 and multiple connecting rod assemblies 42. The column assemblies 41 are arranged separately along the horizontal direction of the supporting base 1. Each adjacent column assembly 41 is connected by multiple connecting rod assemblies 42. The intermediate curtain 32 includes multiple curtain units 321, which are installed between adjacent column assemblies 41 and connected by zippers. This structure, using multiple column assemblies 41 and connecting rod assemblies 42 to form the telescopic frame mechanism 4, enables telescopic functionality, thereby allowing the intermediate curtain 32 to extend and retract to adapt to different cutting scenarios. The zipper connection between adjacent curtain units 321 ensures the sealing of the intermediate curtain 32 during extension and retraction, preventing dust from escaping through the gaps between the curtain units 321. The telescopic frame mechanism 4 has a total extension stroke of approximately 4000 mm, a total length of approximately 4500 mm when extended, and approximately 500 mm when shortened.

[0032] Each column assembly 41 includes a pair of connecting columns 411 and a connecting beam 412 connected to the pair of connecting columns 411. Each connecting rod assembly 42 includes a pair of connecting rods 421, which are hinged together. The two ends of the connecting rods 421 are connected to adjacent connecting columns 411 or adjacent connecting beams 412. This structural design of the column assemblies 41 and connecting rod assemblies 42 makes the telescopic frame mechanism 4 more flexible and stable in its extension and retraction, and better adaptable to different working requirements. The hinged connection between the connecting rods 421 ensures the smoothness of the extension and retraction process.

[0033] The support base 1 is equipped with a slide rail 11, and the connecting column 411 is mounted on the slide rail 11 via a slider 12. The cooperation between the slide rail 11 and the slider 12 provides guidance for the movement of the connecting column 411, making the telescopic frame mechanism 4 move more smoothly and reliably along the horizontal direction of the support base 1, and reducing friction and resistance during the movement.

[0034] like Figure 3 and Figure 4As shown, the drive mechanism 2 includes an active end connecting plate 21, a driven end connecting plate 22, an active end mounting base 23, a driven end mounting base 24, an active sprocket 25, a driven sprocket 26, a drive motor 27, and a drive chain 28. The active end connecting plate 21 and the driven end connecting plate 22 are both mounted on the support base 1. The active end mounting base 23 is mounted on the active end connecting plate 21. The drive motor 27 is mounted on the active end mounting base 23, and its output end is connected to the active sprocket 25. The driven end mounting base 24 is mounted on the driven end connecting plate 22. The driven sprocket 26 is connected to the driven end mounting base 24. The drive chain 28 is meshed with both the active sprocket 25 and the driven sprocket 26. The drive motor 27 drives the active sprocket 25 to rotate. Through the meshing transmission of the drive chain 28 with the active sprocket 25 and the driven sprocket 26, power is transmitted, thereby driving the telescopic frame mechanism 4 to move. This sprocket and chain drive method has advantages such as high transmission efficiency, large torque transmission, and reliable operation.

[0035] The driving end connecting plate 21 is provided with a driving end adjustment hole 211 for connecting to the driving end mounting base 23, and the driven end connecting plate 22 is provided with a driven end adjustment hole 241 for connecting to the driven end mounting base 24. The driving end adjustment holes 211 and 241 can be elongated holes. The driving end mounting base 23 and the driven end mounting base 24 are fixed to appropriate positions in the driving end adjustment holes 211 and 241 respectively using bolts. The provision of the driving end adjustment holes 211 and 241 facilitates the adjustment of the positions of the driving end mounting base 23 and the driven end mounting base 24, thereby adjusting the distance between the driving sprocket 25 and the driven sprocket 26, facilitating the installation and tensioning of the drive chain 28, and ensuring the stability of the transmission.

[0036] The drive mechanism 2 also includes a guide rod 201 and a connecting block 202. The two ends of the guide rod 201 are connected to the active end connecting plate 21 and the driven end connecting plate 22, respectively. The connecting block 202 is movably connected to the guide rod 201 and fixedly connected to the drive chain 28. One of the connecting columns 411 is fixedly connected to the connecting block 202. The guide rod 201 provides guidance for the movement of the connecting block 202, ensuring the stability of the connecting block 202 as it moves with the drive chain 28. The connecting block 202 transmits the movement of the drive chain 28 to the connecting column 411, thereby driving the entire telescopic frame mechanism 4 to move, making power transmission more direct and reliable.

[0037] The curtain unit 321 is equipped with a transparent plastic film 3211. The transparent plastic film 3211 allows operators to easily observe the cutting process without opening the curtain, thus preventing dust from escaping due to observation. The bottom of the curtain unit 321 is equipped with Velcro, which allows the bottom of the curtain unit 321 to be attached to the support frame 1 or the ground, further enhancing the sealing of the curtain assembly 3 and preventing dust from escaping from the bottom of the curtain.

[0038] The front curtain 31 and the middle curtain 32 are connected by a dustproof cloth, which is then connected to both the front curtain 31 and the middle curtain 32 using buttons and Velcro. The dustproof cloth enhances the sealing of the connection between the front curtain 31 and the middle curtain 32. The buttons bear weight and prevent pulling, while the Velcro prevents dust from escaping. The button and Velcro connection is not only secure but also easy to disassemble and install, facilitating cleaning and replacement of the curtains. The double connection between the dustproof cloth and the front curtain 31 and the middle curtain 32 further enhances the sealing and security of the connection.

[0039] The working principle of the dustproof device used in the wind turbine blade cutting process is as follows: Before cutting the wind turbine blade 7, according to the size and cutting position of the wind turbine blade 7, the drive motor 27 drives the drive sprocket 25 to rotate. The drive sprocket 25 drives the driven sprocket 26 to rotate through the drive chain 28. When the drive chain 28 moves, it drives the connecting block 202 to move along the guide rod 201. The connecting block 202 drives the connecting column 411 connected to it to move along the slide rail 11, thereby causing the telescopic frame mechanism 4 to extend and retract, adjusting the position and length of the middle curtain 32 so that the curtain assembly 3 can completely surround the cutting area. During the cutting process, the front curtain 31, the middle curtain 32, and the rear curtain 33 work together to prevent dust from escaping. At the same time, the dust filtration and recovery mechanism 5 recovers and filters the dust generated during cutting. The operator can observe the cutting situation through the transparent plastic film 3211 on the curtain unit 321.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] This utility model, by setting a curtain assembly 3, including a front curtain 31, a middle curtain 32 and a rear curtain 33, can effectively block the dust generated during the cutting process and prevent the dust from spilling into the working environment. The telescopic frame mechanism 4 can move horizontally along the support base 1. Driven by the drive mechanism 2, it can be flexibly adjusted according to the length of the wind turbine blade 7 and the cutting position, thus improving the applicability of the device.

[0042] The dust filtration and recycling unit 5 can recycle and filter the dust generated during cutting, which not only reduces dust pollution but also allows for the recycling and reuse of dust, thus saving resources.

[0043] A transparent plastic film 3211 is installed on the curtain unit 321 to facilitate the operator's observation of the cutting process. The Velcro at the bottom of the curtain unit 321 enhances the dustproof effect.

[0044] The drive mechanism 2 has a reasonable structural design. Through the cooperation of the drive sprocket 25, the driven sprocket 26 and the drive chain 28, it drives the telescopic frame mechanism 4 to move smoothly. The setting of the drive end adjustment hole 211 and the driven end adjustment hole 241 makes it convenient to adjust the tension of the drive chain 28, ensuring the stable operation of the mechanism.

[0045] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
