Description

Technical Field

[0001] The present invention relates to the technical field of retired wind turbine blade processing, and particularly to a cutting device for retired wind turbine blades. Background Art

[0002] Since wind power projects are mostly located in remote areas with long transportation distances, and retired wind turbine blades are large in size and high in recycling cost, the current economic efficiency of processing wind turbine blades is poor. Before physically recycling waste wind turbines, the wind turbine blades should be removed and cut into plates, blocks, strips, etc. of different sizes according to actual uses. The main materials of wind turbine blades are generally composites of glass fiber and epoxy resin, with high strength and good mechanical properties, and can maintain good structural quality even after retirement.

[0003] In related technologies, mechanical cutting or water cutting methods are usually used to cut the composite materials of wind turbine blades. When cutting the blades, a clamping component is required to clamp the blades to keep them fixed. Among them, when using the water cutting method to cut the blades, due to the large weight of the water knife component, generally the water knife component is fixed and the blade moves following it. However, each time the blade is moved, the clamping of the blade by the clamping component needs to be unlocked to ensure the smooth movement of the blade. This setting makes the movement operation of the blade cumbersome and prone to tipping left and right during the movement, resulting in low cutting efficiency of the blade. Summary of the Invention

Detailed implementation manners

[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0029] The following will be combined with Figures 1 - 4 Describe a retired wind turbine blade cutting device according to an embodiment of the present invention.

[0030] The retired wind turbine blade cutting device according to the embodiment of the present invention includes a workbench 1, a water jet assembly 2, a blade supply assembly 4 and a clamping assembly 3. The workbench 1 is used to support the part of the blade 6 to be cut. The water jet assembly 2 is installed on the workbench 1 and is used to cut the blade 6. The blade supply assembly 4 is used to drive the blade 6 to move in the first direction. The clamping assembly 3 is arranged upstream of the workbench 1 along the first direction. The clamping assembly 3 includes two clamping members and two elastic members. The two clamping members are arranged at intervals along the second direction, and the second direction is orthogonal to the first direction. One of the elastic members connects one of the clamping members and the workbench 1, and the other elastic member connects the other clamping member and the workbench 1. The two clamping members are adapted to clamp the blade 6 under the pressure of the two elastic members.

[0031] For the retired wind turbine blade cutting device according to an embodiment of the present invention, when the blade 6 is placed between the two clamping members, the two elastic members will be deformed by the pressing of the two clamping members. Under the action of the resilience of the two elastic members, the two clamping members can clamp and limit the blade 6, ensuring that the position of the blade 6 is fixed during the cutting process, and the cutting reliability of the blade 6 is high. Moreover, when it is necessary to move the blade 6 in the first direction, it is not necessary to release the clamping and limiting of the blade 6 by the two clamping members. During the movement of the blade 6, the two clamping members also play a role in limiting the blade 6 in the second direction, and the movement consistency of the blade 6 in the first direction is higher, and thus the cutting efficiency of the blade 6 is higher.

[0032] It should be noted that the water jet assembly 2 includes an ultra-high pressure water pump, a cutting robotic arm, a water tank and an abrasive supply device. The cutting robotic arm is equipped with a cutting head, and the cutting head is connected to the ultra-high pressure pump through a high-pressure pipe. The water tank and the abrasive supply device are used to ensure the continuous supply of water and abrasive. The skid-mounted cutting equipment for retired wind turbine blades further includes a power system, which can be a diesel generator set to supply power to electrical components such as the water jet assembly 2 and the winch 41, ensuring the independent and reliable operation of the skid-mounted cutting equipment for retired wind turbine blades in the wild.

[0033] In some embodiments, the clamping assembly 3 further includes two substrates 31 installed on the workbench 1. The two substrates 31 are arranged at intervals in the second direction and are arranged in mirror symmetry. The two clamping members and the two elastic members are located between the two substrates 31. One clamping member is connected to one substrate 31 through one elastic member, and the other clamping member is connected to the other substrate 31 through the other elastic member.

[0034] That is, the elastic member is connected to the workbench 1 through the substrate 31. The setting of the substrate 31 makes the layout flexibility of the elastic member in the height direction higher, and the clamping and limiting reliability of the two clamping members for the blade 6 is higher.

[0035] Exemplarily, as Figure 4 described, the two substrates 31 are parallel to each other and vertically arranged above the workbench 1. The clamping assembly 3 further includes two sets of triangular reinforcing rib plates. The two sets of triangular reinforcing rib plates are both connected to the workbench 1 and are respectively arranged on both sides of the two substrates 31 relative to each other. Thereby, while further improving the connection strength between the substrate 31 and the workbench 1, it also effectively avoids the deformation of the substrate 31 from affecting the clamping reliability of the two clamping members for the blade 6.

[0036] In some embodiments, the clamping assembly 3 further includes two brackets 32. The two brackets 32 are arranged at intervals in the second direction and are located between the two substrates 31. Each bracket 32 is movably connected to the adjacent substrate 31 in the second direction. The elastic member includes a first spring 36. Each bracket 32 is connected to the adjacent bracket 32 by the first spring 36. The clamping member includes a first roller 33. The axial direction of the first roller 33 is consistent with the up-and-down direction. The first roller 33 is mounted on each bracket 32.

[0037] Under the action of the first spring 36, the two clamping members apply at least a clamping force in the second direction to the blade 6, and the limiting reliability of the blade 6 in the second direction is higher. By arranging the bracket 32 to be movably connected to the substrate 31 in the second direction, it effectively ensures that when the first spring 36 is compressed and deformed, it undergoes radial deformation and does not affect the clamping reliability of the clamping member on the blade 6. At the same time, by clamping and limiting the blade 6 with the first roller 33, when the blade 6 is moved, the first roller 33 and the blade 6 are in rolling cooperation, the movement of the blade 6 is more labor-saving, and the service life of the clamping assembly 3 is longer.

[0038] Specifically, as Figure 4 shown, four groups of first springs 36 are correspondingly arranged on each bracket 32. On the projection plane perpendicular to the second direction, the projections of the four groups of first springs 36 are arranged at the four corners. The bracket 32 is slidably connected to the substrate 31 through four guide posts extending in the second direction. The first spring 36 is sleeved on the guide post and is clamped between the bracket 32 and the substrate 31.

[0039] It should be noted that the guide posts on the side of the substrate 31 facing away from the bracket 32 are connected to the other guide posts through baffles, thereby effectively preventing the guide posts and the bracket 32 from detaching from the substrate 31.

[0040] In some embodiments, the clamping member includes two groups of second rollers 34 and two groups of first guide rods. The two groups of second rollers 34, the two groups of first guide rods, the two brackets 32 and the two substrates 31 correspond one by one. The second roller 34 is located above the bracket 32. The axial direction of the second roller 34 forms an angle with the up-and-down direction and the second direction and is orthogonal to the first direction. The lower end of the second roller 34 is pivotally connected to the corresponding bracket 32. The upper end of the second roller 34 is located on the side of the corresponding bracket 32 facing away from the corresponding substrate 31. The upper end of the second roller 34 is pivotally connected to the lower end of the corresponding first guide rod. The upper end of the first guide rod is movably connected to the corresponding substrate 31 along the axial direction of the first guide rod. The elastic member further includes a second spring 37. The second spring 37 is sleeved on the first guide rod and is located between the lower end of the first guide rod and the corresponding substrate 31.

[0041] Under the action of the rebound force of the second spring 37, the second roller 34 will exert an oblique downward force on the blade 6, effectively preventing the blade 6 from gradually deviating upward during the movement along the first direction, and the part to be cut of the blade 6 can be moved to the set position more accurately, and the cutting reliability of the blade 6 is higher. In addition, the second roller 34 and the blade 6 are in rolling cooperation, and the second roller 34 is less worn when clamping the limiting blade 6, and the service life of the clamping assembly 3 is longer.

[0042] Specifically, a limiting flange is provided at the lower end of the first guide rod, and the second spring 37 is sandwiched between the limiting flange and the base plate 31. Three second springs 37 are correspondingly provided for each bracket 32, and the three second springs 37 are arranged at intervals along the first direction.

[0043] In some embodiments, the clamping member includes two groups of third rollers 35 and two groups of second guide rods, and the two groups of third rollers 35, the two groups of second guide rods, the two brackets 32 and the two substrates 31 correspond to each other. The third roller 35 is located below the bracket 32, the axial direction of the third roller 35 is at an angle with the up-down direction and the second direction and is orthogonal to the first direction, the upper end of the third roller 35 is pivotally connected to the corresponding bracket 32, the lower end of the third roller 35 is located on the side of the corresponding bracket 32 ​​away from the corresponding substrate 31, the lower end of the third roller 35 is pivotally connected to the upper end of the corresponding second guide rod, and the lower end of the second guide rod is movably connected to the corresponding substrate 31 along the axial direction of the second guide rod, and the elastic member also includes a third spring 38, which is sleeved on the second guide rod and located between the upper end of the second guide rod and the corresponding substrate 31.

[0044] The third roller 35, under the action of the rebound force of the third spring 38, will exert an oblique upward force on the blade 6, and the clamping assembly 3 will exert a greater upward supporting force on the blade 6, so that the blade 6 is less likely to deviate in height and left and right angles during movement, and the part to be cut of the blade 6 can be moved to the set position more accurately, and the cutting reliability of the blade 6 is higher. In addition, the third roller 35 and the blade 6 are in rolling cooperation, and the third roller 35 is less worn when clamping the limited blade 6, and the service life of the clamping assembly 3 is longer.

[0045] For example, Figure 4 As shown, a limiting flange is provided at the upper end of the second guide rod, and a third spring 38 is sandwiched between the limiting flange and the base plate 31. Three third springs 38 are provided correspondingly to each bracket 32, and the three third springs 38 are arranged at intervals along the first direction. At this time, the first roller 33, the second roller 34 and the third roller 35 located on the same side surround to form a V-shaped clamping space with an opening toward the other side.

[0046] In some embodiments, the two clamping members are arranged in mirror symmetry, and the two elastic members are arranged in mirror symmetry.

[0047] That is, the clamping assembly 3 forms two clamping modules arranged at intervals in the second direction and mirror-symmetrical to each other. The structure of the clamping assembly 3 is simple, and the manufacturing and installation costs are low. Moreover, this setting also enables the clamping assembly 3 to have a good clamping and limiting effect on the blade 6, and the blade 6 is more easily limited to the central position of the workbench 1 in the second direction.

[0048] In some embodiments, the blade supply assembly 4 includes a lifting platform 42 and a winch 41. The lifting platform 42 is movably arranged upstream of the clamping assembly 3 in the first direction and is used to support the root of the blade 6. The winch 41 is installed on the workbench 1, and the wire on the winch 41 is connected to the lifting platform 42.

[0049] When the blade 6 needs to be moved, the winch 41 on the workbench 1 pulls the lifting platform 42 in the direction close to the workbench 1 through the wire, and the lifting platform 42 pushes the blade 6 to move synchronously. Among them, the blade 6 can achieve the feeding operation in the first direction without displacement in the height direction, the moving efficiency of the blade 6 is high, and the cutting efficiency is high. And during the movement of the blade 6, the clamping assembly 3 can still maintain the clamping and limiting of the blade 6.

[0050] Exemplarily, the blade supply assembly 4 further includes a first guide roller group and a second guide roller group. The first guide roller group is installed on the first table portion 11, the second guide roller group is installed on the third table portion 13, and the wire passes through the first guide roller group and the second guide roller group. Under the guidance of the first guide roller group and the second guide roller group, it effectively avoids the interference between the wire and the workbench 1, the water jet assembly 2 and the clamping assembly 3, and the pulling reliability of the winch 41 on the lifting platform 42 is higher. At the same time, the wire is in rolling cooperation with the first guide roller group and the second guide roller group, the friction between the wire and the first guide roller group and the second guide roller group is smaller, and the service life of the wire is longer.

[0051] In addition, walking wheels are installed at the bottom of the lifting platform 42. There are two winches 41, and the two winches 41 are arranged at intervals in the second direction. This makes it more labor-saving when the winch 41 pulls the lifting platform 42 to move, and the setting of the two winches 41 jointly pulling the lifting platform 42 makes the moving consistency of the lifting platform 42 in the first direction higher.

[0052] In some embodiments, the workbench 1 includes a first table portion 11, a second table portion 12 and a third table portion 13 arranged in sequence in the first direction. The clamping assembly 3 is installed on the first table portion 11, the water jet assembly 2 is installed on the second table portion 12, the second table portion 12 is used to support the to-be-cut part of the blade 6, and the winch 41 is installed on the third table portion 13.

[0053] At this time, the lifting platform 42 is located on the side of the first table portion 11 away from the second table portion 12. By arranging the winch 41 on the third table portion 13, more parts of the blade 6 can be pulled to the water jet assembly 2 for cutting treatment, and the cutting efficiency of the blade 6 is higher.

[0054] For example, Figures 1 - 3 As shown, the first platform 11 and the third platform 13 are both pivotally connected to the second platform 12, that is, after the retired fan blade cutting device completes the cutting operation, the first platform 11 and the third platform 13 can be folded so that the clamping assembly 3, the winch 41 and the water jet assembly 2 thereon are all hidden in the accommodating cavity formed by the workbench 1, so that the retired fan blade cutting device is smaller in size and more convenient to move.

[0055] In some embodiments, Figure 1 and Figure 3 As shown, a plurality of first conveying rollers 5 for supporting blades 6 are installed on the first stage 11, and the plurality of first conveying rollers 5 are located between two clamping members and are configured as a plurality of groups spaced apart along the first direction, and each group of first conveying rollers 5 includes two first conveying rollers 5 spaced apart along the second direction and arranged in a V shape, and the second direction is orthogonal to the first direction and the up-down direction. A plurality of second conveying rollers spaced apart along the first direction are provided on the second stage 12, and the water jet assembly 2 has two groups and is located on opposite sides of the second conveying rollers along the second direction, and the second direction is orthogonal to the first direction and the up-down direction.

[0056] When the blade 6 moves under the pull of the capstan 41, it will roll with the first conveying roller 5 and the second conveying roller. When the first side plate and the bottom plate support the blade 6 through the first conveying roller 5 and the second conveying roller respectively, the movement of the blade 6 is more labor-saving and smooth. In addition, the two first conveying rollers 5 arranged in the second direction surround the V-shaped supporting space with the opening facing upward, which can support the blade 6 and effectively limit the position of the blade 6 in the second direction.

[0057] It should be noted that part of the first conveying roller 5 is located between the two clamping members, and the other part of the first conveying roller 5 is located on the side of the clamping assembly 3 away from the water jet assembly 2. The axial direction of the second conveying roller is consistent with the second direction, thereby ensuring that the second conveying roller can support the blade 6 while not interfering with the water jet assembly 2 in cutting the bottom of the blade 6 located above the bottom plate, so that the water jet assembly 2 has a better cutting effect on the blade 6.

[0058] In some embodiments, the retired wind turbine blade cutting device further includes a wastewater recovery component, which is connected to the workbench 1 and is used to collect wastewater generated when the water jet component 2 is working.

[0059] The wastewater recovery component can collect the wastewater, on the one hand to prevent the wastewater from polluting the local environment, and on the other hand to achieve the reuse of water resources and abrasives in the wastewater.

[0060] For example, a liquid storage tank is provided on the second platform 12, and the wastewater recovery assembly is connected to the liquid storage tank. The liquid storage tank can store wastewater generated when the water jet assembly 2 is working, so as to facilitate the wastewater recovery assembly to recover wastewater and abrasive.
