Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade technology, specifically to a cutting device for processing decommissioned wind turbine blades. Background Technology

[0002] Wind turbine blades are the core components of wind turbine units. Their shape is similar to that of an airplane wing, and they are asymmetrical. When the wind blows over the blades, the airflow velocity is faster above and slower below, thus generating lift. This lift drives the blades to rotate, thereby converting wind energy into mechanical energy, which is then converted into electrical energy by a generator. To reduce resource waste, retired wind turbine blades are pyrolyzed to recover the high-value-added reinforcing fibers. Before pyrolysis, the blades need to be pre-cut and processed by a cutting device.

[0003] Currently, cutting devices lack adaptive adjustment mechanisms. Due to the asymmetrical structure of wind turbine blades, insufficient cutting depth is often caused by shape limitations during actual cutting, requiring repeated manual cutting and resulting in limited flexibility. Therefore, a cutting device for decommissioned wind turbine blade processing is proposed, which incorporates an adaptive adjustment mechanism. By using guiding, rotating, and positioning methods, the device adapts to the horizontality of the wind turbine blade cutting position, improving the quality of each cut and enhancing the flexibility and adaptability of the device, thereby improving its effectiveness.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To facilitate the use of guiding, rotating, and positioning methods to adapt to the horizontality of the wind turbine blade cutting position, thereby improving the performance, such as... Figure 1-4 As shown, the present invention provides a cutting device for processing decommissioned wind turbine blades, including an electric slide table 1, a leveling component 3, and a recycling component 6. The top of the electric slide table 1 is slidably connected to a frame 2, the frame 2 is provided with the leveling component 3, and the frame 2 is provided with recycling components 6 on both sides.

[0032] The leveling component 3 includes a mounting frame 301, a rotating frame 302 is mounted on the bottom of the mounting frame 301 via a bearing, a protective cover 303 is provided on the bottom of the rotating frame 302, a guide component 4 is provided between the rotating frame 302 and the protective cover 303, and a cutting component 5 is slidably connected inside the protective cover 303.

[0033] The guide assembly 4 includes a sleeve 401, which is slidably connected to the bottom of the rotating frame 302. A sleeve rod 402 is sleeved and connected to the bottom of the sleeve 401, and one end of the sleeve rod 402 is rotatably connected to the top of the protective cover 303 via a rotating shaft.

[0034] In use, the mounting bracket 301, rotating bracket 302, protective cover 303, sleeve 401, and sleeve rod 402 can be used to add an adaptive adjustment mechanism. By rotating, flipping, and positioning, it can automatically adapt to different wind turbine blade cutting positions, thereby improving the accuracy and convenience of cutting and processing.

[0035] The bottom of the protective cover 303 is glued with an anti-slip pad.

[0036] To improve the utilization rate of recycling, for example, such as Figure 1, Figure 5 As shown, the present invention also includes the following: the recycling component 6 includes a recycling box 601, an exhaust fan 602 is bolted to the outside of the recycling box 601, and the air inlet of the exhaust fan 602 is located inside the recycling box 601; the bottom of the recycling box 601 is connected to a material discharge chute 603 by a snap fastener.

[0037] During use, the auxiliary recycling mechanism can be added through the recycling box 601, the exhaust fan 602 and the material drop chute 603. The dust generated during the cutting process is filtered and recycled by suction, so that it can be sent into the pyrolysis equipment for pyrolysis and recycling, while reducing resource waste.

[0038] For example, such as Figure 1 , 3 As shown, this utility model also includes a sliding groove 306 at the bottom of the rotating frame 302, a slider 307 slidably connected in the sliding groove 306, and a sleeve 401 rotatably connected to the bottom of the slider 307 via a rotating shaft. A stepper motor 308 is bolted to the top of the mounting frame 301, and the stepper motor 308 is connected to the rotating frame 302 via a drive shaft. A compression spring 403 is installed in the sleeve 401 at the top of the sleeve rod 402 via a spring seat. A cylinder 7 is bolted to the top of the frame 2, and the output end of the cylinder 7 is bolted to the mounting frame 301.

[0039] In use, the slide groove 306 and slider 307 facilitate the adaptive positioning of the protective cover 303 by sliding to make the guide component 4 tilt accordingly. The stepper motor 308 facilitates the rotation of the rotating frame 302 to adjust the operating angle. The compression spring 403 facilitates the use of elastic force to push the sleeve rod 402 down for adaptive positioning. The cylinder 7 can drive the mounting frame 301 down to adjust the cutting height position. A return spring is installed in the slide groove 306 on one side of the slider 307 via a spring seat.

[0040] For example, such as Figure 2 , 3 As shown in Figure 5, the present invention also includes a filter screen 604 provided in the recycling bin 601 on one side of the material discharge trough 603, a discharge port 304 on both sides of the protective cover 303, and the discharge port 304 is connected to the recycling bin 601 through a flexible hose, and an air inlet 305 is provided on the surface of the protective cover 303.

[0041] During use, the material drawn into the recycling box 601 can be filtered, screened and stored through the filter screen 604. Through the discharge port 304 and the air inlet 305, the heat, dust and impurities generated by cutting can be easily carried away from the protective cover 303 for recycling and treatment by external air. The air inlet 305 includes a one-way valve.

[0042] For example, such as Figure 2 , 6 As shown, this utility model also includes a cutting assembly 5 comprising a support frame 501, a cutting bracket 502 slidably connected to the bottom of the support frame 501, a cutting blade 503 rotatably connected inside the cutting bracket 502 via a rotating shaft, the cutting bracket 502 comprising a protective cover 504, a cutting motor 505 bolted to the surface of the cutting bracket 502, the cutting motor 505 being connected to the cutting blade 503 via a drive shaft, an electric push rod 309 bolted to the top of the protective cover 303, and the output end of the electric push rod 309 bolted to the support frame 501.

[0043] In use, the support frame 501, cutting bracket 502, cutting blade 503, protective cover 504, cutting motor 505 and electric push rod 309 form a cutting mechanism to continuously cut and process retired wind turbine blades.

[0044] For example, such as Figure 6 As shown, the present invention also includes a lead screw 506 mounted on the top of the support frame 501 via a bearing, a corresponding ball slider 507 sleeved around the lead screw 506, and the ball slider 507 connected to the cutting bracket 502 via bolts. A servo motor 508 is bolted to one side of the support frame 501, and the servo motor 508 is connected to the lead screw 506 via a drive shaft.

[0045] In use, the cutting bracket 502 can be adjusted in position and the cutting range and area can be adjusted by using the lead screw 506, ball slider 507, and servo motor 508.

[0046] In use, the electric slide table 1 is manually activated to drive the frame 2 to slide to the cutting position of the decommissioned wind turbine blade. The cylinder 7 is manually activated to drive the mounting bracket 301 to slide down to the top of the wind turbine blade. The spring 403 pushes the sleeve rod 402 to slide down, so that the protective cover 303 can tilt according to the horizontality of the cutting position of the decommissioned wind turbine blade, so that the protective cover 303 can adapt to the shape of the wind turbine blade and form protection around the cutting mechanism. Then, the cutting motor 505 and the servo motor 508 are manually activated. The cutting motor 505 drives the cutting blade 503 to rotate to cut the wind turbine blade. At the same time, the servo motor 508 drives the lead screw 506 to rotate, and the ball slider 507 drives the cutting bracket 502 to move back and forth to adjust the cutting range and area. The electric push rod 309 can also be manually activated to drive the support frame 501 to slide down to adjust the height and cutting depth of the cutting component 5 to adapt to different usage needs.

[0047] Furthermore, during the actual cutting and processing, the exhaust fan 602 can be manually turned on to draw outside air into the protective cover 303 through the air inlet 305. The negative pressure generated by the suction draws the dust and waste generated during cutting into the recycling box 601 through the discharge port 304. The dust and waste are then filtered by the filter screen 604 for auxiliary recycling. This not only reduces dust pollution of the working environment but also reduces the waste of fan blades by recycling them, making them easier to send to the pyrolysis equipment for heat treatment. The overall structure is simple, low-cost, easy to operate, and more flexible and reliable in use.
