Description

Technical Field

[0001] This invention relates to the field of wind turbine blade recycling technology, specifically to a wind turbine blade dismantling device and dismantling method. Background Technology

[0002] Wind turbine blades are mainly made of composite materials, with glass fiber reinforced resin (GRP, accounting for over 90%) as the core component. Some large blades contain carbon fiber reinforced resin (CFRP). A single blade can weigh several tons and occupy a large area. At present, environmentally friendly recycling methods involve cutting the blades and then crushing them (physical) to obtain fillers or building materials, or decomposing and recycling the cut blades (solvent, high temperature or catalyst decomposition) to obtain recycled high-value materials.

[0003] For example, Chinese patent CN205888252U describes a wire saw cutting device for wind turbine blades, comprising: a wire saw main unit, a fixture frame, a first hydraulic pump, and a second hydraulic pump. A traveling mechanism is installed at the lower end of the fixture frame. A push rod perpendicular to the plane of the fixture frame is provided on the side end of the fixture frame. One end of the push rod is mounted on the fixture frame, and the other end has a handle. At least two sets of guide wheels for winding the rope are installed on the push rod. All guide wheel sets are located on the same plane, which is perpendicular to the plane of the fixture frame and does not intersect with the fixture frame. Fastening buckles are installed at the upper and lower ends of the fixture frame. Two support plates perpendicular to the plane of the fixture frame are also installed on the side of the fixture frame away from the push rod. The wire saw main unit is fixed on the fixture frame and connected to the first and second hydraulic pumps respectively via hydraulic pipes. This design facilitates clamping and improves cutting efficiency.

[0004] However, as the cutting depth increases, the required saw rope length for wind turbine blades decreases. The aforementioned structure cannot tension the saw rope, which easily leads to the saw rope being in a slack state. A slack saw rope has low cutting efficiency and is not conducive to rapid cutting. At the same time, water is added during cutting to cool it down. The water causes the cutting debris to stick to the saw rope. The debris moves along the guide wheel, and the squeezing pressure can easily damage the saw rope, shortening its service life. In addition, adding water can easily cause the saw rope to slip on the drive wheel, which is not conducive to stable drive and results in high energy consumption.

[0005] Based on this, the present invention designs a wind turbine blade disassembly device and disassembly method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wind turbine blade dismantling device and dismantling method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A wind turbine blade dismantling device includes a chassis, a tracked drive unit, and a sawing rope;

[0009] Two sets of track drive devices are symmetrically fixedly installed at the bottom of the chassis, and the movement direction of the track drive devices is set perpendicular to the cutting direction of the saw rope;

[0010] The top of the chassis is fixedly connected to an adjustable rope guide assembly for guiding the saw rope. When not disassembled, the adjustable rope guide assembly is adjusted to a folded state, and when disassembled, the adjustable rope guide assembly is adjusted to an unfolded state.

[0011] The adjustable guide rope assembly is connected to a follow-up counterweight guide assembly for guiding the saw rope. The follow-up counterweight guide assembly and the adjustable guide rope assembly work together to tension the saw rope.

[0012] The side wall of the chassis is connected to a drive assembly for moving the saw rope, a linkage striking assembly for striking the saw rope, a first guide wheel for guiding the saw rope, and a second guide wheel for guiding the saw rope. The drive assembly is connected to an auxiliary clamping assembly for squeezing the saw rope inside the drive assembly. The auxiliary clamping assembly, drive assembly, linkage striking assembly, first guide wheel, and second guide wheel are all located below the follow-up counterweight guide assembly. The linkage striking assembly is located between the drive assembly and the second guide wheel and is connected to the drive assembly. The second guide wheel is located below the first guide wheel, and the central axis of the linkage striking assembly is higher than the central axis of the drive assembly and the central axis of the second guide wheel. The top of the second guide wheel is higher than the bottom of the drive assembly.

[0013] The chassis houses a battery and a controller. The battery is electrically connected to the controller, track drive equipment, adjustable guide rope assembly, and follow-up counterweight guide assembly. The controller is communicatively connected to the follow-up counterweight guide assembly, adjustable guide rope assembly, and drive assembly.

[0014] Furthermore, an L-shaped hanging rod is symmetrically and fixedly connected to the end face of the chassis away from the second guide wheel.

[0015] Furthermore, the drive assembly includes a drive wheel and a first motor. The first motor is fixedly installed on the inner wall of the chassis. The drive end of the first motor passes through the chassis and is fixedly connected to the drive wheel. The drive wheel is connected to the auxiliary clamping assembly and is connected to the linkage striking assembly via transmission.

[0016] Furthermore, the auxiliary clamping assembly includes an arc-shaped plate, ball bearings, a first spring, and a pressing post. The drive wheel, with its circumferentially spaced sliding holes near the side wall of the chassis, slides in contact with the pressing post. The end of the pressing post away from the chassis is in contact with the saw rope inside the drive wheel. The two ends of the first spring are fixedly connected to the drive wheel near the side wall of the chassis and the end of the pressing post near the chassis, respectively, and the first spring is sleeved on the pressing post. The ball bearings are rotatably mounted on the end of the pressing post near the chassis. The arc-shaped plate is fixedly mounted on the outer side wall of the chassis, and the center of the arc-shaped plate coincides with the center of the drive wheel. The arc-shaped plate has inclined grooves at both ends, and the arc length of the arc-shaped plate is less than the arc length of the saw rope inside the drive wheel. The position where the saw rope contacts the drive wheel completely covers both ends of the arc-shaped plate.

[0017] Furthermore, the linkage striking assembly includes a first pulley, a belt, a second pulley, a connecting shaft, a rotating plate, and rotating bearings. The connecting shaft is rotatably connected to the outer wall of the chassis via bearings. The rotating plate is fixedly mounted on the connecting shaft. Two sets of rotating bearings are rotatably mounted at both ends of the rotating plate. The second pulley is fixedly mounted on the outer end of the connecting shaft. The first pulley is fixedly mounted on the outer end of the drive wheel. The belt is rotatably connected to the first and second pulleys. The saw rope moves below the rotating bearings.

[0018] Furthermore, the adjustable guide rope assembly includes an adjustable guide structure, an adjustable drive assembly, a guide wheel assembly, and a position monitoring assembly. The adjustable guide structure is fixedly connected to the top of the chassis, the adjustable guide structure is rotatably connected to the adjustable drive assembly, the adjustable drive assembly is movably connected to the guide wheel assembly, the guide wheel assembly is connected to the position monitoring assembly, and the position monitoring assembly is connected to the adjustable guide assembly.

[0019] Furthermore, the adjustable guide structure includes a support plate, hooks, hinges, connecting plates, hanging rods, first guide rods, second guide rods, circular insert rods, a top plate, a second push plate, and a second spring. The support plate is fixedly installed on the top of the chassis. The top of the side wall of the support plate away from the drive assembly is fixedly connected to the hinge. The hinge is fixedly connected to the connecting plate. The connecting plate is fixedly connected to the top plate. Two sets of first guide rods are symmetrically fixedly installed inside the top of the top plate. The adjustable drive assembly is rotatably connected to the top of the top plate. The hooks are rotatably installed on the side wall of the support plate and are used in conjunction with the hooks. The hanging rod is fixedly installed on the side wall of the connecting plate. The bottom of the first guide rod has a sliding hole, and the first guide rod has a first movable groove on the side wall of the sliding hole. The first movable groove is slidably connected to the second push plate. The second push plate is fixedly connected to the circular insert rod, and the circular insert rod is slidably connected to the sliding hole. The second spring is fixedly installed between the top of the circular insert rod and the top of the sliding hole. The top of the second guide rod has a circular insertion hole for inserting into the circular insert rod. The second guide rod is fixedly installed on the top of the chassis. Both the second guide rod and the first guide rod are slidably connected to the guide wheel assembly.

[0020] Furthermore, the adjustable drive assembly includes a first threaded rod, a second threaded rod, a second motor, a polygonal insert, a first push plate, and a third spring. The second motor is fixedly installed inside the chassis, and the drive end of the second motor is fixedly connected to the bottom of the first threaded rod. The top of the first threaded rod has a first polygonal insertion hole, and the bottom of the second threaded rod has a second polygonal insertion hole. The second threaded rod has a second movable groove on the side wall of the second polygonal insertion hole. The first push plate is slidably connected to the second movable groove. The first push plate is fixedly connected to the polygonal insert. The polygonal insert is slidably connected to the second polygonal insertion hole and the first polygonal insertion hole. The third spring is fixedly installed between the top of the polygonal insert and the top of the second polygonal insertion hole. When the bottom of the second threaded rod and the top of the first threaded rod are in contact, a complete set of threaded rods is formed.

[0021] Furthermore, the guide wheel assembly includes a second slider and a fourth guide wheel. The second slider is slidably connected to the first guide rod or the second guide rod through a sliding hole. Two sets of fourth guide wheels are rotatably mounted on the end of the second slider near the drive assembly. The second slider is threadedly connected to the second threaded rod or the first threaded rod through a threaded sleeve.

[0022] A method for disassembling a wind turbine blade disassembly device includes the following steps:

[0023] Step 1: Loop the saw rope around the outside of the wind turbine blades, and then wrap the saw rope around the drive assembly, the second guide wheel, the first guide wheel, the follow-up counterweight guide assembly, and the adjustable guide rope assembly. The drive assembly drives the saw rope to rotate along the drive assembly. The saw rope moves towards the wind turbine blades through the adjustable guide rope assembly, the follow-up counterweight guide assembly, and the first guide wheel. The saw rope moves on the wind turbine blades to cut them.

[0024] Step 2: As the length of the saw rope covering the wind turbine blades decreases, the follow-up counterweight guide assembly moves downward adaptively under the action of gravity. When the guide end of the follow-up counterweight guide assembly moves to the bottom, the guide end of the adjustable rope guide assembly moves upward. The adjustable rope guide assembly drives the follow-up counterweight guide assembly to move through the saw rope until the follow-up counterweight guide assembly is in the set position. Repeat the position adjustment of the guide ends of the adjustable rope guide assembly and the follow-up counterweight guide assembly, and the saw rope is always in a taut state.

[0025] Beneficial Effects: This invention involves placing a saw rope around the outside of a wind turbine blade, then winding the saw rope around a drive assembly, a second guide wheel, a first guide wheel, a follow-up counterweight guide assembly, and an adjustable guide rope assembly. The drive assembly drives the saw rope to rotate along the drive assembly. The saw rope moves towards the wind turbine blade through the adjustable guide rope assembly, the follow-up counterweight guide assembly, and the first guide wheel. The saw rope moves on the wind turbine blade to cut it. As the length of the saw rope covering the wind turbine blade decreases, the follow-up counterweight guide assembly adaptively moves downwards under gravity. When the guide end of the follow-up counterweight guide assembly moves to its lowest point, the guide end of the adjustable guide rope assembly moves upwards. The adjustable guide rope assembly drives the follow-up counterweight guide assembly to move through the saw rope until the follow-up counterweight guide assembly is in a set position. The guide end of the adjustable guide rope assembly then moves upwards repeatedly. The position adjustment of the guide end of the follow-up counterweight guide component ensures that the saw rope is always under tension, guaranteeing a stable connection between the saw rope and the fan blades, thus ensuring cutting effect and improving cutting efficiency. When the drive component rotates, it drives the linkage striking component to rotate. The rotating linkage striking component intermittently contacts the moving saw rope, intermittently striking the saw rope, which helps to knock away impurities adhering to the saw rope, reducing the friction coefficient between the saw rope and the drive component, reducing the load on the drive component, and extending the service life of the saw rope. When the drive component rotates, the auxiliary clamping component can squeeze the saw rope inside the drive component, keeping the saw rope and the drive component in a relatively fixed state, preventing relative sliding of the saw rope within the drive component, and ensuring the driving stability of the drive component.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] The present invention will be further described below with reference to embodiments.

[0045] Example 1: Please refer to Figures 1-14 A wind turbine blade dismantling device includes a housing 1, a track drive device 3, and a saw rope 8;

[0046] Two sets of track drive devices 3 are symmetrically fixedly installed at the bottom of the chassis 1, and the moving direction of the track drive devices 3 is set perpendicular to the cutting direction of the saw rope 8.

[0047] An adjustable rope guide assembly 9 for guiding the saw rope 8 is fixedly connected to the top of the chassis 1. When not disassembled, the adjustable rope guide assembly 9 is adjusted to a folded state, and when disassembled, the adjustable rope guide assembly 9 is adjusted to an unfolded state.

[0048] The adjustable rope guide assembly 9 is connected to a follow-up counterweight guide assembly 7 for guiding the saw rope 8. The follow-up counterweight guide assembly 7 and the adjustable rope guide assembly 9 work together to tension the saw rope 8.

[0049] The side wall of the chassis 1 is connected to a drive assembly 5 for moving the saw rope 8, a linkage striking assembly 6 for striking the saw rope 8, a first guide wheel 10 for guiding the saw rope 8, and a second guide wheel 11 for guiding the saw rope 8. The drive assembly 5 is connected to an auxiliary clamping assembly 4 for squeezing the saw rope 8 inside the drive assembly 5. The auxiliary clamping assembly 4, drive assembly 5, linkage striking assembly 6, first guide wheel 10, and second guide wheel 11 are all located below the follow-up counterweight guide assembly 7. The linkage striking assembly 6 is located between the drive assembly 5 and the second guide wheel 11. The linkage striking assembly 6 is connected to the drive assembly 5 in a transmission manner. The second guide wheel 11 is located below the first guide wheel 10, and the central axis of the linkage striking assembly 6 is higher than the central axis of the drive assembly 5 and the central axis of the second guide wheel 11. The top of the second guide wheel 11 is set higher than the bottom of the drive assembly 5.

[0050] The chassis 1 houses a battery 12 and a controller 13. The battery 12 is electrically connected to the controller 13, the track drive device 3, the adjustable guide rope assembly 9, and the follow-up counterweight guide assembly 7. The controller 13 is communicatively connected to the follow-up counterweight guide assembly 7, the adjustable guide rope assembly 9, and the drive assembly 5.

[0051] The saw rope 8 is looped around the outside of the wind turbine blade, and then wound around the drive assembly 5, the second guide wheel 11, the first guide wheel 10, the follow-up counterweight guide assembly 7, and the adjustable guide rope assembly 9. The drive assembly 5 drives the saw rope 8 to rotate along the drive assembly 5. The saw rope 8 moves towards the wind turbine blade through the adjustable guide rope assembly 9, the follow-up counterweight guide assembly 7, and the first guide wheel 10. The saw rope 8 moves on the wind turbine blade to cut it. As the coverage length of the saw rope 8 on the wind turbine blade decreases, the follow-up counterweight guide assembly 7 moves downward adaptively under the action of gravity. When the guide end of the follow-up counterweight guide assembly 7 moves to the lowest point, the guide end of the adjustable guide rope assembly 9 moves upward. The adjustable guide rope assembly 9 drives the follow-up counterweight guide assembly 7 to move through the saw rope 8 until the follow-up counterweight guide assembly 7 is in the set position. The movement of the guide end of the adjustable guide rope assembly 9 and the follow-up counterweight guide assembly 9 is repeated. The position adjustment of the guide end of the movable counterweight guide component 7 ensures that the saw rope 8 is always in a taut state, guaranteeing a stable connection between the saw rope 8 and the fan blades, thus ensuring the cutting effect and improving cutting efficiency. When the drive component 5 rotates, it drives the linkage striking component 6 to rotate. The rotating linkage striking component 6 intermittently contacts the movable saw rope 8, achieving intermittent striking of the saw rope 8. This helps to knock away impurities adhering to the saw rope 8, reducing the friction coefficient between the saw rope 8 and the drive component 5, reducing the load on the drive component 5, and extending the service life of the saw rope 8. When the drive component 5 rotates, the auxiliary clamping component 4 can squeeze the saw rope 8 inside the drive component 5, keeping the saw rope 8 and the drive component 5 in a relatively fixed state. This prevents the saw rope 8 from sliding relative to the drive component 5 and ensures the driving stability of the drive component 5.

[0052] Please see Figure 1 An L-shaped hanging rod 2 is symmetrically and fixedly connected to the end face of the chassis 1 away from the second guide wheel 11;

[0053] The saw rope 8 is wound in a figure-eight shape around the two sets of L-shaped hanging rods 2, so that the saw rope 8 can be stored without disassembling it.

[0054] Please see Figure 1 , Figure 4 , Figure 10 The drive assembly 5 includes a drive wheel 51 and a first motor 52. The first motor 52 is fixedly installed on the inner wall of the housing 1. The drive end of the first motor 52 passes through the housing 1 and is fixedly connected to the drive wheel 51. The drive wheel 51 is connected to the auxiliary clamping assembly 4 and is connected to the linkage striking assembly 6.

[0055] The first motor 52 of the drive assembly 5 drives the drive wheel 51 to rotate, and the drive wheel 51 drives the saw rope 8 to rotate along the drive wheel 51. The moving saw rope 8 cuts the wind turbine blade. When the drive wheel 51 rotates, it drives the linkage striking assembly 6 to rotate. The rotating linkage striking assembly 6 intermittently contacts the moving saw rope 8, realizing intermittent striking of the saw rope 8. This helps to knock away impurities adhering to the saw rope 8, reduces the friction coefficient between the saw rope 8 and the drive wheel 51, reduces the load on the first motor 52, and extends the service life of the saw rope 8. When the drive wheel 51 rotates, the auxiliary clamping assembly 4 can squeeze the saw rope 8 inside the drive wheel 51, so that the saw rope 8 and the drive wheel 51 are relatively fixed, which can prevent the saw rope 8 from sliding relative to the drive wheel 51 and ensure the driving stability of the drive assembly 5.

[0056] Please see Figure 1 , Figure 5 , Figure 6 The auxiliary clamping assembly 4 includes an arc-shaped plate 41, a ball bearing 42, a first spring 43, and a pressing post 44. The drive wheel 51 is slidably connected to the pressing post 44 by sliding holes that are equally spaced along the circumference of the side wall of the housing 1. The end of the pressing post 44 away from the housing 1 is in contact with the saw rope 8 inside the drive wheel 51. The two ends of the first spring 43 are fixedly connected to the drive wheel 51 near the side wall of the housing 1 and the end of the pressing post 44 near the housing 1, respectively. The first spring 43 is sleeved on the pressing post 44. The ball bearing 42 is rotatably installed on the end of the pressing post 44 near the housing 1. The arc-shaped plate 41 is fixedly installed on the outer side wall of the housing 1, and the center of the arc-shaped plate 41 coincides with the center of the drive wheel 51. The arc-shaped plate 41 has inclined grooves 45 at both ends. The arc length of the arc-shaped plate 41 is less than the arc length of the saw rope 8 inside the drive wheel 51. The position of the saw rope 8 in contact with the drive wheel 51 completely covers both ends of the arc-shaped plate 41.

[0057] When the drive wheel 51 rotates, it drives the saw rope 8 and the first spring 43 of the auxiliary clamping assembly 4 to rotate. The first spring 43 drives the pressing post 44 to rotate, and the pressing post 44 drives the ball 42 to rotate. The ball 42 rotates until it contacts the inclined groove 45 at one end of the arc plate 41. The inclined groove 45 guides the ball 42 to move toward the drive wheel 51. The ball 42 drives the pressing post 44 to move toward the drive wheel 51. The pressing post 44 contacts the saw rope 8 and presses the saw rope 8 against the drive wheel 51. When the drive wheel 51 rotates, the auxiliary clamping assembly 4 can squeeze the saw rope 8 inside the drive wheel 51, so that the saw rope 8 and the drive wheel 51 are relatively fixed. This can prevent the saw rope 8 from sliding relative to the drive wheel 51, ensuring the driving stability of the drive assembly 5. When the ball 42 contacts the arc plate 41, the first spring 43 is always in a compressed state.

[0058] When the ball bearing 42 moves to the inclined groove 45 at the other end of the arc plate 41, the first spring 43 drives the ball bearing 42 to move towards the housing 1. The ball bearing 42 drives the pressing post 44 to move towards the housing 1. The pressing post 44 separates from the part of the saw rope 8 that it contacts. Then the drive wheel 51 separates from the part of the saw rope 8 that it contacts.

[0059] Please see Figure 1 , Figure 4 The linkage striking assembly 6 includes a first pulley 61, a belt 62, a second pulley 63, a connecting shaft 64, a rotating plate 65, and a rotating bearing 66. The connecting shaft 64 is rotatably connected to the outer wall of the housing 1 through the bearing. The rotating plate 65 is fixedly installed on the connecting shaft 64. Two sets of rotating bearings 66 are rotatably installed at both ends of the rotating plate 65. The second pulley 63 is fixedly installed at the outer end of the connecting shaft 64. The first pulley 61 is fixedly installed at the outer end of the drive wheel 51. The belt 62 is rotatably connected to the first pulley 61 and the second pulley 63. The saw rope 8 moves below the rotating bearing 66.

[0060] While the drive wheel 51 moves the saw rope 8, it also drives the first pulley 61 of the linkage striking assembly 6 to rotate. The first pulley 61 drives the second pulley 63 to rotate via the belt 62. The second pulley 63 drives the connecting shaft 64 to rotate, which in turn drives the rotating plate 65 to rotate. The rotating plate 65 then drives the rotating bearing 66 to rotate. The rotating bearing 66 intermittently contacts the saw rope 8, thus intermittently striking the saw rope 8. This helps to knock away impurities adhering to the saw rope 8, reduces the coefficient of friction between the saw rope 8 and the drive assembly 5, reduces the load on the drive assembly 5, and extends the service life of the saw rope 8.

[0061] Please see Figures 1-5 , Figures 7-14 The adjustable guide rope assembly 9 includes an adjustable guide structure, an adjustable drive assembly, a guide wheel assembly, and a position monitoring assembly. The adjustable guide structure is fixedly connected to the top of the chassis 1, the adjustable guide structure is rotatably connected to the adjustable drive assembly, the adjustable drive assembly is movably connected to the guide wheel assembly, the guide wheel assembly is connected to the position monitoring assembly, and the position monitoring assembly is connected to the adjustable guide assembly.

[0062] The adjustable guide structure includes a support plate 91, a hook 92, a hinge 94, a connecting plate 95, a hanging rod 96, a first guide rod 99, a second guide rod 910, a circular insert rod 915, a top plate 918, a second push plate 924, and a second spring 927. The support plate 91 is fixedly installed on the top of the chassis 1. The top of the side wall of the support plate 91 away from the drive assembly 5 is fixedly connected to the hinge 94. The hinge 94 is fixedly connected to the connecting plate 95. The connecting plate 95 is fixedly connected to the top plate 918. Two sets of first guide rods 99 are symmetrically fixedly installed inside the top of the top plate 918. The adjustable drive assembly is rotatably connected to the top of the top plate 918. The hook 92 is rotatably installed on the side wall of the support plate 91. The hanging rod 96, which cooperates with the hook 92, is fixedly installed on the top of the support plate 91. The first guide rod 99 is fixedly installed on the side wall of the connecting plate 95. The bottom of the first guide rod 99 has a sliding hole 920. The first guide rod 99 has a first movable groove 925 on the side wall of the sliding hole 920. The first movable groove 925 is in close contact with the second push plate 924 and is slidably connected. The second push plate 924 is fixedly connected to the circular insertion rod 915. The circular insertion rod 915 is in close contact with the sliding hole 920 and is slidably connected. The second spring 927 is fixedly installed between the top of the circular insertion rod 915 and the top of the sliding hole 920. The top of the second guide rod 910 has a circular insertion hole 917 for insertion into the circular insertion rod 915. The second guide rod 910 is fixedly installed on the top of the chassis 1. The second guide rod 910 and the first guide rod 99 are both in close contact with the guide wheel assembly and are slidably connected.

[0065] The top plate 918 is rotatably connected to the second threaded rod 97;

[0066] The outer end of the first push plate 923 is located on the inner side of the outer wall of the second threaded rod 97.

[0067] The guide wheel assembly includes a second slider 913 and a fourth guide wheel 914. The second slider 913 is slidably connected to the first guide rod 99 or the second guide rod 910 through a sliding hole. The two sets of fourth guide wheels 914 are rotatably mounted on the end of the second slider 913 near the drive assembly 5.

[0069] When disassembly is not required, the second motor 919 of the adjustable drive assembly drives the first threaded rod 93 to rotate, the first threaded rod 93 drives the second threaded rod 97 to rotate, the second threaded rod 97 drives the guide wheel assembly to move the second slider 913 downward, the second slider 913 drives the fourth guide wheel 914 to move downward, and at the same time, the follower counterweight guide assembly 7 moves downward to the lowest point under the action of gravity, and the second slider 913 continues to move downward until it comes into contact with the follower counterweight guide assembly 7, pushing the first push plate 923 and the second push plate upward. Plate 924, first push plate 923 drives polygonal insert rod 922 to separate from first polygonal insert hole 916, second push plate 924 drives circular insert rod 915 to separate from circular insert hole 917, drives connecting plate 95 to rotate along hinge 94, connecting plate 95 rotates to contact support plate 91, connecting plate 95 drives the bottom of first guide rod 99 and second threaded rod 97 to rotate upward, then hook 92 to hang rod 96, folding and storing adjustable guide rope assembly 9 to reduce space occupation and facilitate transportation or storage.

[0070] When disassembly is required, separate the hook 92 from the hanging rod 96, push the connecting plate 95 to rotate along the hinge 94, the hinge 94 drives the top plate 918 to rotate, the top plate 918 drives the first guide rod 99 and the second threaded rod 97 to rotate, push the first push plate 923 and the second push plate 924 upward, the first push plate 923 drives the polygonal insert rod 922 to move completely into the second polygonal insert hole 921, the second push plate 924 drives the circular insert rod 915 to move completely into the sliding hole 920, and continue to drive the first guide rod 99 and the second threaded rod 97 to rotate until the first guide rod 99 and the second guide rod 910 are in contact, and the second threaded rod 97 and the first threaded rod 93 are in contact. Release the first push plate 92. 3. The second push plate 924 and the second spring 927 drive the circular insert 915 into the circular insertion hole 917, realizing the alignment and connection of the first guide rod 99 and the second guide rod 910. The third spring 928 drives the polygonal insert 922 into the first polygonal insertion hole 916, realizing the alignment and connection of the second threaded rod 97 and the first threaded rod 93. Since the polygonal insert 922 is polygonal, it can ensure that the first threaded rod 93 can drive the second threaded rod 97 to rotate. The second motor 919 drives the first threaded rod 93 to rotate. The first threaded rod 93 drives the second slider 913 to move along the first threaded rod 93. The second slider 913 drives the fourth guide wheel 914 and the second sensing block 911 to move. The third sensing... When the second sensor 912 senses the second sensing block 911, the second motor 919 stops. The guide end of the follow-up counterweight guide assembly 7 is adjusted to its highest position. The saw rope 8 is then wrapped around the top of the drive assembly 5, the second guide wheel 11, the first guide wheel 10, the follow-up counterweight guide assembly 7, and the fourth guide wheel 914. The drive assembly 5 drives the saw rope 8 to rotate along it. The saw rope 8 moves towards the wind turbine blades via the fourth guide wheel 914, the follow-up counterweight guide assembly 7, and the first guide wheel 10. The saw rope 8 cuts the wind turbine blades as it moves along them. As the length of the saw rope 8 covering the wind turbine blades decreases, the follow-up counterweight guide assembly 7 adaptively moves downwards under gravity. When the guide end of component 7 moves to the lowest point, the second motor 919 drives the first threaded rod 93 to rotate, the first threaded rod 93 drives the second threaded rod 97 to rotate, and the first threaded rod 93 or the second threaded rod 97 drives the second slider 913 to move upward. The second slider 913 drives the fourth guide wheel 914 to move upward. The fourth guide wheel 914 drives the follow-up counterweight guide component 7 to move through the saw rope 8 until the follow-up counterweight guide component 7 is in the set position. The position adjustment of the guide end of the fourth guide wheel 914 and the follow-up counterweight guide component 7 is repeated to ensure that the saw rope 8 is always in a taut state, ensuring that the saw rope 8 and the fan blade are in a stable engagement state, ensuring the cutting effect, and improving the cutting efficiency.

[0071] The first guide rod 99 or the second guide rod 910 is in close sliding connection with the follow-up counterweight guide assembly 7.

[0072] Please see Figure 1 , Figure 3 , Figure 4 The follow-up counterweight guide assembly 7 includes a first position sensor 71, a second position sensor 72, a first slider 73, a counterweight 74, a third guide wheel 75, and a first sensing block 76. The first slider 73 is slidably connected to the first guide rod 99 or the second guide rod 910 through a sliding hole. The third guide wheel 75 is rotatably mounted on the end of the first slider 73 near the drive assembly 5, and the first slider 73 is located between two sets of fourth guide wheels 914. The counterweight 74 is fixedly mounted on the end of the first slider 73 away from the drive assembly 5. The first sensing block 76 is fixedly mounted on the side wall of the counterweight 74. The first position sensor 71 and the second position sensor 72 are fixedly mounted on the side wall of the support plate 91, with the first position sensor 71 located above the second position sensor 72.

[0073] As the saw rope 8 rotates and cuts, the length of the saw rope 8 covering the fan blades decreases. The counterweight block 74 of the follow-up counterweight guide assembly 7 drives the first slider 73 to move downwards along the first threaded rod 93. The first slider 73 drives the third guide wheel 75 to move downwards. The fourth guide wheel 914 and the third guide wheel 75 work together to tension the saw rope 8. The counterweight block 74 drives the first sensing block 76 to move downwards. When the first position sensor 71 senses the first sensing block 76, the second motor 919 drives the first threaded rod 93 to rotate. The first threaded rod 93 drives the second threaded rod 97 to rotate. The first threaded rod 93 or the second threaded rod 97 drives the second slider 913 to move upwards. The slider 913 drives the fourth guide wheel 914 to move upward. The fourth guide wheel 914 drives the third guide wheel 75 to move upward through the saw rope 8. The third guide wheel 75 drives the first slider 73 to move upward. The first slider 73 drives the counterweight 74 to move downward. The counterweight 74 drives the first sensing block 76 to move upward. When the second position sensor 72 senses the first sensing block 76, the first sensing block 76 moves to the top. At this time, the second motor 919 stops rotating. The position adjustment of the fourth guide wheel 914 and the third guide wheel 75 is repeated to ensure that the saw rope 8 is always in a taut state, ensuring that the saw rope 8 and the fan blades are in a stable engagement state, ensuring the cutting effect, and improving the cutting efficiency.

[0074] Because the two sets of fourth guide wheels 914 and one set of third guide wheels 75 work together to temporarily store the saw rope 8, the cutting of the wind turbine blade at the current position can be completed before the third position sensor 98 senses the second sensing block 911.

[0075] When the third position sensor 98 detects the second sensing block 911, the second motor 919 stops rotating and cannot continue to adjust the second slider 913 to move upward, thus performing the top protection.

[0076] A method for disassembling a wind turbine blade disassembly device includes the following steps:

[0077] Step 1: Place the saw rope 8 on the outside of the wind turbine blade, and then wrap the saw rope 8 around the drive assembly 5, the second guide wheel 11, the first guide wheel 10, the follow-up counterweight guide assembly 7, and the adjustable guide rope assembly 9. The drive assembly 5 drives the saw rope 8 to rotate along the drive assembly 5. The saw rope 8 moves towards the wind turbine blade through the adjustable guide rope assembly 9, the follow-up counterweight guide assembly 7, and the first guide wheel 10. The saw rope 8 moves on the wind turbine blade to cut the wind turbine blade.

[0078] Step 2: As the length of the saw rope 8 covering the wind turbine blades decreases, the follow-up counterweight guide assembly 7 moves downward adaptively under the action of gravity. When the guide end of the follow-up counterweight guide assembly 7 moves to the lowest point, the guide end of the adjustable rope guide assembly 9 moves upward. The adjustable rope guide assembly 9 drives the follow-up counterweight guide assembly 7 to move through the saw rope 8 until the follow-up counterweight guide assembly 7 is in the set position. The positions of the guide ends of the adjustable rope guide assembly 9 and the follow-up counterweight guide assembly 7 are adjusted repeatedly, and the saw rope 8 is always in a taut state.
