[0037] Specifically, the material 9 fixed by the fixing fixture 1 in the present invention mainly refers to irregularly shaped materials 9, and the irregularly shaped materials 9 have curvatures, such as wind turbine blades for recycling and reuse. If the irregularly shaped materials 9 are not firmly fixed, it will affect the cutting quality and cutting efficiency. The material 9 has two opposite wall surfaces, and the concave surface of the material 9 is defined as the inner wall surface of the material 9, and the convex surface of the material 9 is defined as the outer wall surface of the material 9. The material 9 is placed on a workbench, and the inner wall surface of the material 9 is opposite to the workbench.

The length direction of the material 9 is consistent with the length direction of the workbench, the length direction of the material 9 is the longitudinal direction, and the width direction of the material 9 is the transverse direction. The fixing fixture 1 of the present invention is described in detail below.

[0038] The first telescopic member 101 is a mechanism capable of performing telescopic motion, and may be a mechanism such as a cylinder, an oil cylinder or an electric push rod. For example, the first telescopic member 101 is a cylinder, and this cylinder is defined as a first cylinder, including a first cylinder body and a first piston rod, the first cylinder body is a fixed end, and the first piston rod is a free end. The second telescopic member 102 is also a mechanism capable of performing telescopic motion, and may be a mechanism such as a cylinder, an oil cylinder or an electric push rod. For example, the second telescopic member 102 is also a cylinder, and this cylinder is defined as a second cylinder, including a second cylinder body and a second piston rod, the second cylinder body is a fixed end, and the second piston rod is a free end.

[0039] The two first cylinders are arranged at intervals, and the fixed ends of the two first cylinders are installed on the cross beam 104, that is, the two first cylinder bodies are installed on the cross beam 104 at intervals, and the two first cylinder bodies are movably connected to the cross beam 104, that is, the first cylinder bodies can move along the cross beam 104, the first cylinder bodies can be slidably connected to the cross beam 104, and the first piston rod can perform telescopic movement in the vertical direction, and a through hole is provided at the end of the first piston rod away from the first cylinder body.

[0040] The two second cylinders are arranged at intervals, and the two second cylinders are arranged one by one with the two first cylinders. The second cylinder body can be connected to the outer side of the first cylinder body through a connecting piece, and the second cylinder body can also be connected to the end of the first piston rod away from the first cylinder body through a connecting piece. For example, the second cylinder body is connected to the end of the first piston rod. The second piston rod can perform telescopic movement in the vertical direction, or the second piston rod can perform telescopic movement in the horizontal direction.

[0041] The material of the flexible belt 103 can be flexible materials such as Dupont, polyester or nylon, and the length of the flexible belt 103 is set according to actual needs. One end of the flexible belt 103 is connected to the free end of a second piston plate after passing through a through hole of a first piston rod, and the other end of the flexible belt 103 is connected to the free end of another second piston rod after passing through a through hole of another first piston rod. The free end of the second piston rod can also be provided with a through hole, and the flexible belt 103 is connected to the through hole of the second piston rod through a connecting piece such as a hook after passing through the through hole of the first piston rod, thereby realizing the connection between the flexible belt 103 and the first cylinder and the second cylinder.

[0042] The following is a detailed description of the use of the fixing fixture 1. The material 9 is placed on the workbench, and the inner wall surface of the material 9 is opposite to the workbench. Before the material 9 is fixed, the two first cylinders and the two second cylinders are in the initial position, and the flexible belt 103 is in a relaxed state and away from the material 9. The two first cylinders move in opposite directions along the crossbeam 104, so that the distance between the two first cylinders increases, and the distance between the two first cylinders is greater than the width of the material 9, and then the two first piston rods move downward in the vertical direction until they contact the workbench. The two first piston rods are respectively located on the outside of the first end of the material 9 and the outside of the second end of the material 9. At this time, the two first cylinders move toward each other until one first piston rod abuts against the end face of the first end of the material 9, and the other first piston rod abuts against the end face of the second end of the material 9, thereby clamping the material 9 through the two first piston rods.

[0043] When the two second piston rods are arranged in the vertical direction, the two second piston rods move upward in the vertical direction, driving the two ends of the flexible belt 103 to move in the direction away from the through hole of the first piston rod until the flexible belt 103 is close to the outer wall of the material 9, thereby the flexible belt 103 presses the material 9. When the two second piston rods are arranged in the horizontal direction, the two second piston rods move away from each other in the horizontal direction, driving the two ends of the flexible belt 103 to move in the direction away from the through hole of the first piston rod until the flexible belt 103 is close to the outer wall of the material 9, thereby the flexible belt 103 presses the material 9. The two first piston rods clamp the two opposite end faces of the material 9, and the flexible belt 103 presses the material 9, thereby the material 9 can be firmly fixed on the workbench. Then the material 9 is cut along the longitudinal direction or the horizontal direction of the material 9 by the cutting tool, and the cutting quality is high. After the cutting operation is completed, the first piston rod and the second piston rod move in opposite directions, so that the flexible belt 103 is in a relaxed state, and the cut material 9 can be removed from the workbench.

[0044] In an embodiment of the present invention, two first telescopic members 101 are used to clamp two opposite end faces of the material 9, and two second telescopic members 102 are used to drive both ends of the flexible belt 103 to move in a direction away from the through hole of the first telescopic member 101, so that the flexible belt 103 presses the material 9, thereby ensuring the firmness of the fixation of the material 9, which is beneficial to improving the cutting quality.

[0045] like Figure 1 and Figure 2 As shown, in an optional embodiment, the free end of the second telescopic member 102 is arranged in parallel with the free end of the first telescopic member 101 .

[0046] Specifically, the first telescopic member 101 and the second telescopic member 102 can both be cylinders, the first telescopic member 101 includes a first cylinder body and a first piston rod, and the second telescopic member 102 includes a second cylinder body and a second piston rod. The first piston rod can reciprocate in the vertical direction, and the second piston rod can also reciprocate in the vertical direction. The axis of the second cylinder body is parallel to the axis of the first cylinder body, and the second cylinder body can be connected to the side of the first cylinder body, and the second cylinder body can also be connected to the first piston rod.

[0047] The flexible belt 103 passes through the through hole of the first piston rod and is connected to the end of the second piston rod. The first piston rod and the second piston rod are arranged in parallel, which is conducive to the compactness of the structure. At the same time, the flexible belt 103 can meet the use requirements in a shorter size, which is conducive to reducing the production cost.

[0048] In the embodiment of the present invention, the free end of the first telescopic member 101 is arranged parallel to the free end of the second telescopic member 102, and the flexible belt 103 passes through the through hole of the free end of the first telescopic member 101 and is connected to the free end of the second telescopic member 102, which has a compact structure and low manufacturing cost.

[0049] like Figure 1 and Figure 2 As shown, in an optional embodiment, the fixing fixture 1 also includes a third telescopic member 105; one end of the third telescopic member 105 is connected to the fixed end of a first telescopic member 101, and the other end of the third telescopic member 105 is connected to the fixed end of another first telescopic member 101, so as to adjust the distance between the two first telescopic members 101.

[0050] The third telescopic member 105 can be a mechanism such as a cylinder, an oil cylinder or an electric push rod. For example, the third telescopic member 105 is also a cylinder, and this cylinder is defined as a third cylinder. The third cylinder includes a third cylinder body and a third piston rod. The third cylinder is arranged horizontally, the third cylinder body is connected to one first cylinder body, and the end of the third piston rod is connected to another first cylinder body.

[0051] The third piston rod extends outward, pushing one of the two first telescopic members 101 to move away from the other, thereby increasing the distance between the two first telescopic members 101; the third piston rod retracts inward, driving one of the two first telescopic members 101 to move closer to the other, thereby reducing the distance between the two first telescopic members 101.

[0052] During the process of clamping the material 9, first, a first piston rod abuts against one end of the material 9, and the third piston rod is retracted inward to drive another first cylinder body to move toward the first cylinder body close to the first end of the material 9, until another first piston rod abuts against the other end of the material 9. The spacing between the two first telescopic members 101 is adjusted by the third telescopic member 105 to match materials 9 of different widths, and the operation is convenient.

[0053] In the embodiment of the present invention, the fixed end and the free end of the third telescopic member 105 are respectively connected to the fixed ends of the two first telescopic members 101. The distance between the two first telescopic members 101 can be conveniently adjusted through the telescopic movement of the third telescopic member 105, which is conducive to improving work efficiency.

[0054] In an optional embodiment, the fixing fixture 1 also includes a pressure regulating valve assembly; the pressure regulating valve assembly includes a first pressure regulating valve and a second pressure regulating valve; the first pressure regulating valve is connected to the third telescopic member 105 to adjust the clamping force of the first telescopic member 101 on the material 9; the second pressure regulating valve is connected to the second telescopic member 102 to adjust the clamping force of the flexible belt 103 on the material 9.

[0055] Specifically, the first pressure regulating valve is connected to the third cylinder, and the first pressure regulating valve can adjust the pressure of the compressed air introduced into the third cylinder, so that the two first piston rods can clamp the material 9 at the first preset pressure. The second pressure regulating valve is connected to the second cylinder, and the second pressure regulating valve can adjust the pressure of the compressed air introduced into the second cylinder, so that the two second piston rods can tighten the flexible belt 103, and the flexible belt 103 can be pressed against the outer wall surface of the material 9 at the second preset pressure, thereby ensuring the firmness of the fixation of the material 9. The magnitude of the first preset pressure value and the magnitude of the second preset pressure value are set according to parameters such as the thickness of the material 9.

[0056] In the embodiment of the present invention, the first pressure regulating valve is used to enable the two first piston rods to clamp the opposite ends of the material 9 at a preset pressure, and the second pressure regulating valve is used to enable the flexible belt 103 to be pressed against the outer wall surface of the material 9 at a preset pressure, which is further beneficial to ensure the firmness of the fixation of the material 9.

[0057] Combine the following Figure 3 and Figure 4 A decommissioned wind turbine blade cutting device according to an embodiment of the present invention is described.

[0058] like Figure 3 and Figure 4 As shown, the retired wind turbine blade cutting device provided in an embodiment of the present invention includes: a loading platform 3, a cutting mechanism and the above-mentioned fixing fixture 1; the loading platform 3 is used to be arranged on the top of the loading rack 2, and the loading platform 3 is used to place the wind turbine blade 5; the fixing fixture 1 is arranged on the loading rack 2, and is used to fix the wind turbine blade 5; the cutting mechanism includes a cutting unit, and the cutting unit moves along a first direction to cut the wind turbine blade 5.

[0059] Specifically, the carrier 2 can be a frame structure, and the loading platform 3 is located at the top of the carrier 2. The loading platform 3 is used to place the wind turbine blade 5. The width direction of the carrier 2 is defined as the first direction, and the length direction of the carrier 2 is defined as the second direction. The wind turbine blade 5 is placed on the loading platform 3, and the lateral direction of the wind turbine blade 5 is consistent with the first direction, and the longitudinal direction of the wind turbine blade 5 is consistent with the second direction.

[0060] A support column 4 is provided on one side of the carrier 2. The top of the support column 4 is connected to the crossbeam 104 of the fixing fixture 1. The length direction of the crossbeam 104 is consistent with the first direction. Two first telescopic members 101 are movably connected to the crossbeam 104. The first telescopic member 101 includes a first piston rod, and the second telescopic member 102 includes a second piston rod. In the initial position, the two first piston rods are in a retracted state, and the two second piston rods are in an extended state, so that the flexible belt 103 is in a relaxed state. The concave surface of the wind turbine blade 5 is defined as the inner wall surface of the wind turbine blade 5, and the convex surface of the wind turbine blade 5 is defined as the outer wall surface of the wind turbine blade 5. The two ends of the wind turbine blade 5 in the width direction are defined as the first end of the wind turbine blade 5 and the second end of the wind turbine blade 5, respectively. The wind turbine blade 5 is placed on the loading platform 3. The transverse direction of the wind turbine blade 5 is consistent with the first direction, the longitudinal direction of the wind turbine blade 5 is consistent with the second direction, and the inner wall surface of the wind turbine blade 5 is opposite to the loading platform 3.

[0061] After the wind turbine blade 5 is placed on the loading platform 3, the horizontal spacing between the two first telescopic parts 101 is first adjusted to be larger than the width of the wind turbine blade 5, and then the two first piston rods are moved downward in the vertical direction until the ends of the two first piston rods are in contact with the top surface of the loading platform 3, and the first telescopic part 101 located on one side of the loading frame 2 is moved in the first direction so that the first piston rod abuts against the first end of the wind turbine blade 5, and then the first telescopic part 101 located on the other side of the loading frame 2 is moved in the first direction so that the other first piston rod abuts against the second end of the wind turbine blade 5, thereby clamping the opposite ends of the wind turbine blade 5 by the two first piston rods.

[0062] Then the two second piston rods move upward in the vertical direction, and the two second piston rods drive the two ends of the flexible belt 103 to move in the direction away from the through hole on the first telescopic member 101 until the flexible belt 103 is in a tensioned state, whereby the flexible belt 103 can be pressed against the outer wall surface of the wind turbine blade 5, and the contact area between the flexible belt 103 and the wind turbine blade 5 is large, which is conducive to pressing the wind turbine blade 5. The two first piston rods clamp the opposite ends of the wind turbine blade 5, and the two second piston rods pull the flexible belt 103, so that the flexible belt 103 can press the wind turbine blade 5, thereby achieving a firm fixation of the wind turbine blade 5.

[0063] The cutting mechanism includes a cutting unit, which includes a saw blade 6. The saw blade 6 moves along a first direction from the second end of the wind turbine blade 5 toward the first end of the wind turbine blade 5. The cutting operation is completed by the translational and rotational movement of the saw blade 6. The wind turbine blade 5 is firmly fixed, thereby achieving high cutting quality.

[0064] After cutting, the two second piston rods move downward in the vertical direction, and the two first piston rods move upward in the vertical direction. The two first piston rods and the two second piston rods move to the initial position, and the flexible belt 103 is in a relaxed state, so that the cut recovery blade can be removed from the stage 3.

[0065] Furthermore, the two ends of the third telescopic member 105 are respectively connected to the two first telescopic members 101, and the third piston rod extends outward to increase the distance between the two first telescopic members 101; the third piston rod retracts inward to reduce the distance between the two first telescopic members 101, and the distance between the two first piston rods can be conveniently adjusted by the telescopic movement of the third piston rod. In addition, by adjusting the air pressure entering the third cylinder, the clamping force of the two first piston rods on the wind turbine blade 5 can be controlled. By adjusting the air pressure entering the two second cylinders, the pressing force of the flexible belt 103 on the wind turbine blade 5 can be controlled.

[0066] In the embodiment of the present invention, two first telescopic members 101 are used to clamp the opposite ends of the wind turbine blade 5, and two second telescopic members 102 are used to make the flexible belt 103 press the wind turbine blade 5, so that the wind turbine blade 5 is firmly fixed; the cutting unit moves from the second end of the wind turbine blade 5 to the first end of the wind turbine blade 5 along the first direction, and the wind turbine blade 5 is cut by the translational and rotational movements of the saw blade 6, and the cutting quality is high.

[0067] In an optional embodiment, the cutting mechanism further includes a driving member, which drives the cutting unit to reciprocate along the first direction.

[0068] Specifically, the driving member is a mechanism capable of reciprocating motion, such as a synchronous belt conveying mechanism, a gear rack conveying mechanism, a sprocket chain conveying mechanism or a screw transmission mechanism, etc. For example, the driving member is a synchronous belt conveying mechanism, and the cutting unit is connected to a synchronous belt slide of the synchronous belt conveying mechanism, and the synchronous belt slide drives the cutting unit to reciprocate along the first direction.

[0069] Before the cutting operation starts, the cutting unit is located at the initial position, that is, the second end of the wind turbine blade 5. After the cutting starts, the driving member drives the cutting unit to move along the first direction from the second end of the wind turbine blade 5 toward the first end of the wind turbine blade 5, and a cutting operation is completed through the translational and rotational movement of the saw blade 6.

[0070] After one cutting is completed, the driving member drives the cutting unit to return to the initial position, and then the wind turbine blade 5 moves a preset distance in the second direction and then stops. The preset distance is the width of a recycling blade. The preset distance is set according to actual use requirements, and the cut wind turbine blade is defined as a recycling blade for recycling. The driving member drives the cutting unit to move from the initial position along the first direction from the second end of the wind turbine blade 5 toward the first end of the wind turbine blade 5 to complete the cutting of the next recycling blade. The driving member drives the cutting unit to reciprocate along the first direction to complete the cutting operation of multiple recycling blades, with high work efficiency.

[0071] In the embodiment of the present invention, the driving member drives the cutting unit to reciprocate along the first direction to complete the cutting operation of the plurality of recovery blades, and the working efficiency is high.

[0072] like Figure 3 and Figure 4 As shown, in an optional embodiment, the cutting device for retired wind turbine blades 5 also includes a positioning mechanism 7; the positioning mechanism 7 includes a slider 701 and a positioning member 702, the slider 701 is slidably connected to the carrier 2, and the slider 701 slides along the second direction; the positioning member 702 is movably connected to the slider 701, and the positioning member 702 is used to abut against one side of the wind turbine blade 5; the second direction is perpendicular to the first direction.

[0073] Specifically, a slide rail is provided on the top surface of one side of the object carrier 2, the slider 701 is adapted to the slide rail, the length direction of the slide rail is consistent with the second direction, the slider 701 can slide along the slide rail, the positioning member 702 is movably connected to the slider 701, the positioning member 702 can perform telescopic movement relative to the slider 701 along the first direction, or the positioning member 702 can move toward the direction close to the object carrier 3 or away from the object carrier 3. For example, the positioning member 702 can be a positioning rod, and the positioning rod can perform telescopic movement relative to the slider 701.

[0074] The slider 701 drives the positioning member 702 to move along the slide rail to a preset position. At this time, the distance between the positioning member 702 and the cutting working surface of the saw blade 6 is a distance of a recovered blade width. After the slider 701 moves to the preset position, the positioning member 702 extends. At this time, the wind turbine blade 5 moves along the second direction toward one side of the positioning member 702 until the wind turbine blade 5 abuts against the positioning member 702, and the wind turbine blade 5 stops moving. The fixing fixture 1 fixes the wind turbine blade 5, and the saw blade 6 moves along the first direction to cut the wind turbine blade 5.

[0075] During the cutting process, one end face of the wind turbine blade 5 abuts against the positioning member 702, which can effectively prevent the wind turbine blade 5 from moving in the longitudinal direction, which is beneficial to improving the cutting quality; the wind turbine blade 5 moving in the longitudinal direction not only affects the cutting quality, but also may damage the saw blade 6. The positioning member 702 prevents the wind turbine blade 5 from moving in the longitudinal direction, which is beneficial to ensuring the service life of the cutting unit. After a cutting is completed, the positioning member 702 is retracted, and the cut recovered blade can be removed from the stage 3.

[0076] In the embodiment of the present invention, the slider 701 moves to a preset position, and the positioning member 702 extends out to abut against an end face of the wind turbine blade 5, thereby ensuring the accuracy of the moving distance of the wind turbine blade 5 along the second direction, which is beneficial to improving the cutting accuracy. At the same time, the positioning member 702 can prevent the wind turbine blade 5 from moving along the longitudinal direction, which is beneficial to ensuring the service life of the cutting unit.

[0077] like Figure 3 and Figure 4 As shown, in an optional embodiment, the retired wind turbine blade 5 cutting device further includes a stopper; the stopper is disposed on one side of the top end of the carrier 2 and is used to abut against one end of the wind turbine blade 5 .

[0078] Specifically, the stopper is arranged opposite to the cutting unit, and the stopper includes a baffle 8, and a gap is left between the bottom surface of the baffle 8 and the top surface of the loading platform 3. The wind turbine blade 5 is placed on the loading platform 3, and the end surface of the first end of the wind turbine blade 5 contacts the baffle 8. A first telescopic member 101 is moved along the crossbeam 104 to a position flush with the baffle 8 in the vertical plane, and the third piston rod is extended outward to increase the distance between the two first piston rods, and the distance between the two first piston rods is greater than the width of the wind turbine blade 5. Then the two first piston rods move downward along the vertical direction until the ends of the two first piston rods are close to the top surface of the loading platform 3. In the next step, the third piston rod is retracted inward to reduce the distance between the two first piston rods until the two first piston rods contact the two opposite end surfaces of the wind turbine blade 5 respectively.

[0079] The baffle 8 contacts one end face of the wind turbine blade 5, and performs a preliminary positioning operation on the wind turbine blade 5, which is conducive to the fixing fixture 1 to conveniently fix the wind turbine blade 5. The baffle 8 contacts the first end of the wind turbine blade 5. During the cutting process, the cutting unit moves from the second end of the wind turbine blade 5 toward the first end of the wind turbine blade 5 along the first direction. The baffle 8 can effectively prevent the wind turbine blade 5 from moving in the lateral direction, which is conducive to improving the cutting quality.

[0080] In the embodiment of the present invention, the baffle 8 is in conflict with one end of the wind turbine blade 5, which is beneficial to improving the convenience of fixing the wind turbine blade 5 by the fixing clamp 1; during the cutting process, the cutting unit moves from the other end of the wind turbine blade 5 toward one end of the wind turbine blade 5, and the baffle 8 can effectively prevent the wind turbine blade 5 from moving in the lateral direction, thereby helping to improve the cutting quality.

[0081] like Figure 3 and Figure 4 As shown, in an optional embodiment, the loading platform 3 includes a plurality of rollers 301; the plurality of rollers 301 are spaced apart at the top of the loading frame 2, and the cutting unit is disposed between two adjacent rollers 301; the plurality of rollers 301 rotate synchronously to realize the feeding of the wind turbine blades 5; the rollers 301 on one side of the cutting unit rotate synchronously to realize the discharging of the cut wind turbine blades 5.

[0082] Specifically, multiple rollers 301 are arranged at intervals along the length direction of the carrier 2. The multiple rollers 301 are used to carry the wind turbine blades 5. The wind turbine blades 5 are in contact with the top surfaces of the multiple rollers 301. It can be understood that the top surfaces of the multiple rollers 301 are flush. The cutting unit is located between two adjacent rollers 301, that is, the saw blade 6 for cutting the wind turbine blades 5 is located between the two adjacent rollers 301. The two sides of the saw blade 6 are defined along the length direction of the carrier 3 as the first side of the saw blade 6 and the second side of the saw blade 6. The roller 301 located on the first side of the saw blade 6 is driven to rotate by the first motor, and the roller 301 located on the second side of the saw blade 6 is driven to rotate by the second motor. The rollers 301 on both sides of the saw blade 6 have the same rotation direction.

[0083] The cut wind turbine blades are defined as recycling blades, the saw blade 6 is in the initial position, the first motor and the second motor on both sides of the saw blade 6 are started, and the multiple rollers 301 rotate simultaneously, driving the wind turbine blade 5 to move along the second direction, and the wind turbine blade 5 moves to the preset position. At this time, the distance between the end face of the wind turbine blade 5 and the saw blade 6 is the width of a recycling blade. After the wind turbine blade 5 moves to the preset position, the first motor and the second motor are turned off. The wind turbine blade 5 is fixed by the fixing fixture 1, and then the saw blade 6 cuts the wind turbine blade 5 along the first direction. After the cutting is completed, the fixing fixture 1 releases the fixation of the wind turbine blade 5, and the saw blade 6 returns to the initial position. The first motor is started, and the roller 301 on the first side of the saw blade 6 rotates, driving the cut recycling blade to move, and completing the discharging operation of the recycling blade.

[0084] After the discharge is completed, the first motor and the second motor are started to drive the remaining wind turbine blades 5 to move to the preset position, and the above steps are repeated to perform the next cutting operation. The feeding operation of the wind turbine blades 5 and the discharge operation of the cut and recycled blades can be conveniently realized by the rotation of the roller 301, and the operator does not need to move the wind turbine blades 5, which is conducive to reducing the labor intensity of the operator and improving work efficiency.

[0085] Furthermore, after the recovery blades are discharged, the slide block 701 moves to a preset position along the slide rail, the positioning member 702 extends in the first direction, the first motor and the second motor are started, and the rollers 301 on both sides of the saw blade 6 rotate simultaneously, driving the wind turbine blade 5 to move toward the positioning member 702. After the end face of the wind turbine blade 5 abuts against the positioning member 702, the first motor and the second motor are turned off. The positioning member 702 can accurately control the moving distance of the wind turbine blade 5, thereby facilitating the improvement of cutting accuracy.

[0086] In an embodiment of the present invention, a plurality of rollers 301 are spaced apart at the top of the carrier 2, and the cutting unit is located between two adjacent rollers 301. The rollers 301 on both sides of the cutting unit are driven to rotate by different motors, so that the feeding operation of the wind turbine blades 5 and the discharging operation of the cut and recycled blades can be conveniently realized, with high work efficiency.

[0087] like Figure 3 and Figure 4 As shown, in an optional embodiment, there are multiple fixing clamps 1, and the multiple fixing clamps 1 are arranged on the carrier 2 at intervals.

[0088] Specifically, the number of the fixing clamps 1 is set according to actual needs, and a plurality of fixing clamps 1 are arranged at intervals on the carrier 2. The shape of the wind turbine blade 5 is irregular, and the spacing between the two first piston rods of each fixing clamp 1 can be adjusted according to the shapes of the first end face of the wind turbine blade 5 and the second end face of the wind turbine blade 5 to clamp the two ends of the wind turbine blade 5. The distance that the two second piston rods of each fixing clamp 1 move upward in the vertical direction can be adjusted according to the shape of the outer wall of the wind turbine blade 5, so that the flexible belt 103 can press the wind turbine blade 5.

[0089] The wind turbine blade 5 is clamped and fixed at multiple positions along the longitudinal direction of the wind turbine blade 5 by multiple fixing fixtures 1, so as to improve the firmness of the wind turbine blade 5 and further help improve the cutting quality and cutting accuracy.

[0090] In the embodiment of the present invention, a plurality of fixing clamps 1 are arranged at intervals on the carrier 2 to clamp and fix the wind turbine blade 5 at multiple positions, thereby ensuring the firmness of the wind turbine blade 5 and facilitating the improvement of cutting quality and cutting accuracy.
