Description

Technical Field

[0001] The present invention belongs to the technical field of wind turbine blade recovery, and in particular relates to a device and method for recovering and disposing of retired wind turbine blades. Background Art

[0002] As the scale of the wind power industry continues to increase, my country's wind turbine blades will usher in a large-scale retirement wave. Since the main materials of the wind turbine blade shell are glass fiber and reinforced resin, in order to make effective use of resources, retired wind turbine blades are usually recycled and the glass fiber inside is separated and extracted.

[0003] When performing the recycling operation, the first step is to cut the fan blades into the required length to facilitate their loading into the subsequent crushing device. Therefore, there are many cutting devices for fan blades in the prior art, such as a mobile waste fan blade processing device with patent number CN202410371553.1, which includes a movable frame and a vertical cutting mechanism. The vertical cutting mechanism includes an angle-adjustable rock cutter, and a vertical cutting mechanism is installed on one side of the movable frame. A slide is installed on the inner side of the top of the movable frame, and a winding steel cable is slidably connected to the bottom of the slide, one side of the winding steel cable is connected to an adjusting platform, and a side cutting mechanism is installed at the bottom of the adjusting platform, and a temporary storage support is installed on one side of the movable frame.

[0004] The length of the fan blades in the prior art is relatively large, and the length of the fan blades involved in large fans can reach tens of meters or even hundreds of meters. Therefore, in the above-mentioned prior art, it is to set up a longer slide rail to move the cutting assembly on the slide rail, and then change the cutting position, so as to adapt to the cutting of extra-long fan blades. At the same time, in the prior art, when performing the cutting operation, a conveyor belt matching the length of the fan blades will be built to meet the requirements of cutting and conveying the extra-long fan blades (the cutting position remains unchanged, and after the cutting is completed, the position of the fan blades needs to be conveyed to the cutting position). However, the above two methods will lead to the problems of complex overall structure of the cutting device, large floor space, and high cost. Summary of the invention

[0034] like Figure 1 to Figure 6As shown, a device for recycling and disposing retired wind turbine blades 23 of the present invention comprises a concrete mounting base 1, a rotating plate 2 is symmetrically arranged in the length direction of the concrete mounting base 1, a rotating seat 3 is arranged on one end of the rotating plate 2, and the rotating seat 3 rotatably connects the rotating plate 2 to the concrete mounting base 1, and a supporting plate 24 is arranged between the two rotating plates 2, and both sides of the supporting plate 24 are fixedly connected to the surface of the rotating plate 2, and the length of the supporting plate 24 is less than the length of the rotating plate 2. This design method is to ensure that there is no obstruction of the supporting plate 24 near the other end of the rotating plate 2, so as to facilitate the installation and operation of subsequent components, and one end of the supporting plate 24 is close to the end of the rotating plate 2 away from the rotating seat 3. The two rotating plates 2 are arranged flush, and the limit clamping components for limiting the position of the fan blades 23 are symmetrically arranged on the two rotating plates 2. A mounting frame 9 is arranged on the concrete mounting base 1 near the rotating seat 3. The lower end of the mounting frame 9 is fixed on the concrete mounting base 1. The upper end of the mounting frame 9 is provided with a lifting component, which is used to drive the rotating plate 2 to rotate around the rotating plate 2. The portion of the mounting frame 9 near the concrete mounting base 1 is provided with a cutting component that can reciprocate along the width direction of the mounting frame 9. The cutting component is used to cut the fan blades 23. A conveyor belt 10 is arranged below the cutting component. The conveyor belt 10 is used to convey the fan blade 23 segments after cutting. It is not difficult to understand that a number of support rods can be arranged on the mounting frame 9 to enhance the stability of the mounting frame 9.

[0035] The working principle of this technical solution is:

[0036] The fan blade 23 is placed on the support plate 24, and then the position of the fan blade 23 is limited on the support plate 24 by the limit clamping assembly to prevent the fan blade 23 from shaking and sliding when the support plate 24 rotates, and then the lifting assembly is started to drive the rotating plate 2 to rotate to a vertical tilted state, that is, at this time the fan blade 23 is converted from a horizontal state to a vertical state, that is, at this time the clamping degree of the clamping assembly on the fan blade 23 can be reduced, so that the fan blade 23 falls onto the conveyor belt 10 under the action of gravity, and then the cutting assembly is started to cut the fan blade 23, and the cut segments will move with the movement of the conveyor belt 10, and then be transported Sent to the next process, it is not difficult to understand that the conveyor belt 10 can stop running during cutting, and the conveyor belt 10 can start running after the cutting is completed. The advantage of this is that it can avoid the continuous movement of the conveyor belt 10, and the friction at the end of the fan blade 23 will cause the conveyor belt 10 to wear. Of course, the operation of the conveyor belt 10 can be set according to actual conditions. When a segment is cut, it will automatically fall to the cutting position under the action of gravity of the fan blade 23, and then continue cutting until a fan blade 23 is cut, and then control the support plate 24 to reset and install the next fan blade 23 that needs to be cut.

[0037] Specifically, in an implementable manner, the limit clamping assembly includes a first linear push rod 4 (either electric or hydraulically driven, such as a hydraulic rod), the first linear push rod 4 is fixed on the rotating plate 2, and the output end of the first linear push rod 4 is directed to the middle part of the symmetrically arranged rotating plate 2, a push plate 5 is provided on the output end of the first linear push rod 4, the push plate 5 is fixed on the output end of the first linear push rod 4, a second linear push rod 6 is provided on the upper end of the push plate 5, the second linear push rod 6 is fixed on the push plate 5, and the output end of the second linear push rod 6 is perpendicular to the support plate 24, a pressure plate 7 is provided on the output end of the second linear push rod 6, one end of the pressure plate 7 is connected to the output end of the second linear push rod 6, and when the other end of the second linear push rod 6 is in a working state, it is arranged toward the middle part of the symmetrically arranged rotating plate 2.

[0038] Through the operation of the first linear push rod 4, the push plate 5 pushes the fan blade 23 placed on the support plate 24 to the middle of the support plate 24 for clamping, and then the second linear push rod 6 is started to drive the pressure plate 7 to move downward, squeeze and clamp the upper surface of the fan blade 23, so that the position of the fan blade 23 is relatively fixed, which is convenient for the subsequent rotation of the rotating plate 2.

[0039] In one practicable manner, an external thread is provided on the output end of the second linear push rod 6, the end of the second linear push rod 6 is threadedly connected to the output end of the second linear push rod 6, and when the pressure plate 7 rotates close to the rotating seat 3, the pressure plate 7 is gradually locked on the external thread.

[0040] The pressure plate 7 is rotatably arranged to avoid interference when the fan blades 23 are placed on the support plate 24. At the same time, this arrangement of threaded rotation avoids the friction between the fan blades 23 and the pressure plate 7, which may cause the pressure plate 7 to rotate loosely.

[0041] In one practicable manner, the lifting assembly includes a winch 11 , which is fixed to the upper end of the mounting frame 9 , and the end of a traction rope 12 of the winch 11 is fixed to the outer surface of one end of the rotating plate 2 away from the rotating seat 3 .

[0042] In one practicable manner, the cutting assembly includes a mounting ring 15, the mounting ring 15 can be adjusted in height on the mounting frame 9, the mounting ring 15 can be limited by a clamp or the like, so that position adjustment can be achieved and the stability of the mounting position can be ensured after adjustment. At least one slide 16 is provided between the two mounting rings 15, and a reciprocating cutting saw 17 is provided on the slider of the slide 16, and the saw blade of the reciprocating cutting saw 17 is arranged toward the direction of the rotating plate 2. A fixed beam 26 is provided on the side of the slide 16 facing the rotating plate 2, and the fixed beam 26 is arranged parallel to the saw blade of the reciprocating cutting saw 17. An inclined spring 27 is provided below the fixed beam 26, one end of the inclined spring 27 is fixed to the fixed beam 26, and an inclined pressure plate 25 is provided on the other end of the inclined spring 27, and the middle part of the inclined pressure plate 25 is fixed to the inclined spring 27, one end of the inclined pressure plate 25 is rotatably connected to the slide 17, and the other end of the inclined pressure plate 25 is arranged toward the fan blade 23.

[0043] The slide 16 drives the reciprocating cutting saw 17 to move horizontally to cut the fan blades 23. It is not difficult to understand that the reciprocating cutting saw 17 is a prior art and will not be described in detail here. Preferably, the cutting assembly in the present technical solution is a bidirectional cutting assembly, such as the saw blade of the reciprocating cutting saw 17 is a bidirectional cutting saw blade, that is, saw teeth are set on both sides. The advantage of such a setting is that the reciprocating movement of the slide 16 can cut the fan blades 23, which can reduce the reset process after cutting.

[0044] At the same time, it is not difficult to understand that when the reciprocating cutting saw 17 cuts the fan blade 23, the fan blade 23 will vibrate, that is, when it is disengaged, it may rotate, and thus cannot fall onto the conveyor belt 10 in a manner parallel to the conveyor belt 10, resulting in the problem of conveying being stuck. Therefore, when the fan blade 23 slides downward, it will contact the inclined pressure plate 25 and drive the inclined pressure plate 25 to rotate downward, thereby stretching the inclined tension spring 27, and then applying a force to the fan blade 23, that is, the inclined pressure plate 25 is under the action of the inclined tension spring 27, The middle part of the fan pressure plate 23 is squeezed to prevent it from rotating. At the same time, when the arc-shaped lever 19 pushes the end of the cutting part, the inclined pressure plate 25 will be squeezed and rotated upward, that is, it will not interfere with the process of the cut fan blades 23 falling onto the conveyor belt 10, thereby ensuring that the fan blades 23 fall onto the conveyor belt 10 in a posture parallel to the conveyor belt 10, thereby improving the transportation effect; it is not difficult to understand that the advantage of setting it on the side of the slide 16 is that it can change with the height of the slide 16, thereby adapting to and matching different cutting lengths.

[0045] In one practicable manner, a buffer assembly is provided on one end of the conveyor belt 10 which is arranged close to the rotating plate 2, and the buffer assembly is used to support the conveyor belt 10. The buffer assembly includes an external mounting tube, and a buffer spring is provided in the external mounting tube. One end of the buffer spring is fixed to the inner wall of the lower end of the external mounting tube, and a slider is provided at the other end of the buffer spring. The slider is fixed on the buffer spring, and the slider is slidably connected to the external mounting tube. A sliding rod is provided above the slider, and one end of the sliding rod is fixed on the sliding rod, and the other end of the sliding rod is rotatably connected to the roller end of the conveyor belt 10. This buffer assembly can be understood as a mounting bracket for the conveyor belt 10.

[0046] Avoid the problem that the ends of the fan blades 23 or the segments of the fan blades 23 fall onto the conveyor belt 10 and cause impact damage to the conveyor belt 10 .

[0047] In one feasible manner, a limit plate 8 is provided on the outer side surface of the rotating plate 2, one end of the limit plate 8 is fixed on the rotating plate 2, a baffle rod 13 corresponding to the position of the limit plate 8 is provided on the mounting frame 9, one end of the baffle rod 13 is fixed on the mounting frame 9, and a buffer rubber pad 14 is provided on the other end of the baffle rod 13, and the length of the baffle rod 13 is greater than the distance between the rotating plate 2 and the mounting frame 9 when the rotating plate 2 is rotated to a vertical state.

[0048] The setting of the stopper 13 is to limit the rotation angle of the rotating plate 2, so that the rotating plate 2 can be rotated to a vertical tilted state. When the rotating plate 2 is tilted, there is an obtuse angle between the end of the fan blade 23 and the moving direction of the conveyor belt 10, that is, the cut blade will fall backward under the moving action of the conveyor belt 10, and then lie flat on the conveyor belt 10 as a whole. If the rotating plate 2 is set vertically or at an acute angle to the moving direction of the conveyor belt 10, it is difficult to control the conveying form of the cut fan blade 23 segment on the conveyor belt 10. At the same time, the tilted setting also facilitates the rapid automatic reset of the subsequent support plate 24 under its own gravity.

[0049] In summary, the advantage of the present technical solution is that it transforms the traditional method of cutting the fan blades 23 while lying flat into a method of cutting after rotating the fan blades 23 to a vertical position. In this method, there is no need to establish a longer conveying assembly to change and convey the position of a segment of the fan blade 23 after cutting. Instead, the fan blade 23 is advanced and conveyed to its position after cutting by its own gravity, which greatly simplifies the equipment complexity when cutting extra-long fan blades 23.

[0050] In one feasible manner, a fixed seat 18 is symmetrically provided on one end of the support plate 24 close to the rotating seat 3, one end of the fixed seat 18 is fixed to a side surface of the support plate 24 facing the concrete mounting foundation 1, an arc-shaped lever 19 is rotatably provided on the fixed seat 18, one end of the arc-shaped lever 19 is rotatably connected to the fixed seat 18, and the other end of the arc-shaped lever 19 is located between the symmetrically arranged rotating plates 2, a tensioning spring 20 is provided on the arc-shaped lever 19, one end of the tensioning spring 20 is fixed to the support plate 24, and the other end of the tensioning spring 20 is fixed to the arc-shaped lever 19, under the action of the tensioning spring 20, the arc-shaped lever 19 applies a driving force to the lower end of the cut fan blade 23 segment, and a baffle is provided between one end of the symmetrically arranged rotating plate 2 close to the rotating seat 3, both ends of the baffle are fixed to the rotating plate 2, and the arc-shaped lever 19 is located above the baffle.

[0051] The working principle of the above technical solution is that when the fan blade 23 slides downward on the support plate 24, its outer wall will contact the end of the arc lever 19, and then squeeze the arc lever 19 backward, so that the arc lever 19 rotates backward. At this time, the tension spring 20 is in a stretched state, that is, the end of the arc lever 19 has a pushing force on the contact part of the fan blade 23. When the fan blade 23 segment is cut, the force applied by the arc lever 19 will push the end of the segment in the direction of the conveyor belt movement, thereby further improving the effect of the segment lying flat on the conveyor belt 10 after cutting. Of course, it is not difficult to understand that the degree of compression and timing of the pressing sheet can be set according to actual conditions. For example, when cutting, the pressing sheet presses the fan blade 23, and when the segment cutting is completed and the segment is conveyed to the moving distance, the pressing sheet is released to move the remaining fan blades 23 downward.

[0052] In one feasible manner, a receiving groove 21 is provided on the concrete mounting base 1 at a position corresponding to the position of the arc-shaped lever 19. When the rotating plate 2 is horizontal, the arc-shaped lever 19 is located in the receiving groove 21. A blocking rod 22 is provided at the upper portion of one end of the receiving groove 21 close to the rotating seat 3. Both ends of the blocking rod 22 are fixed on the inner wall of the receiving groove 21. The installation position of the blocking rod 22 corresponds to the position of the protruding portion of the arc-shaped lever 19 in the receiving groove 21.

[0053] The purpose of setting the accommodating groove 21 is to make the arc-shaped lever 19 and other parts located under the "ground" so that the support plate 24 can contact the ground and maintain a horizontal state, thereby improving the convenience of placing the fan blades 23. At the same time, when the support plate 24 moves down to reset, the blocking rod 22 first contacts the protruding part of the arc-shaped lever 19, and then compresses the tension spring 20. The compressed tension spring 20 will buffer the downward movement of the support plate 24, avoiding the problem of excessive impact force between the support plate 24 and the concrete when the support plate 24 is quickly reset, that is, the rapid rotation and reset of the support plate 24 can be achieved (the winch 11 can loosen the lock on the traction rope 12, so that the support plate 24 can be quickly rotated and reset under the action of gravity).

[0054] A method for a retired fan blade 23 recycling and disposal device to cut a fan blade 23 comprises the following steps:

[0055] S1, hoisting and transporting the fan blade 23 to the support plate 24, starting the first linear push rod 4 to push the fan blade 23 to the middle of the support plate 24, and clamping it;

[0056] S2, start the second linear push rod 6 to move the pressure plate 7 downward, pressurize and clamp the upper surface of the fan blade 23, and then clamp and limit the fan blade 23;

[0057] S3, start the winch 11, rotate the support plate 24 by pulling the rope, so that the limit plate 8 of the support plate 24 abuts against the limit rod;

[0058] S4, start the second straight line push rod to make the pressure plate 7 break away from the contact with the fan blade 23, so that the fan blade 23 moves downward under the action of gravity, and the end of the fan blade 23 falls onto the baffle;

[0059] S5. Adjust the position of the mounting ring 15 on the mounting frame 9 so that the cutting length of the reciprocating cutting saw 17 meets the cutting requirements, and then start the reciprocating cutting saw 17 to cut the fan blade 23. After the cutting of one fan blade 23 segment is completed, it is transported to the next process by the conveyor belt 10, and then the fan blade 23 moves downward under the action of gravity to cut the second fan blade 23 segment, and this cycle is repeated until the cutting of the fan blade 23 is completed.

[0060] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
