Abstract
Description
Technical Field
[0001] This invention relates to the field of wind turbine blade cutting technology, and in particular to a water-cutting robot device and water-cutting process for waste wind turbine blades. Background Technology
[0002] Wind power equipment has a limited service life (approximately 20-25 years). After that, its safety and power generation efficiency are significantly reduced.
[0003] Currently, wind turbine blades are gradually reaching their designed lifespan and have entered the aging, scrapping, and replacement period.
[0004] The recycling of decommissioned blades has become a key focus and challenge for the industry. Current research focuses on environmentally friendly cutting, mechanical crushing, pyrolysis (resin decomposition), and chemical degradation (matrix depolymerization), and is accelerating development to achieve environmentally friendly recycling and large-scale application.
[0005] In terms of industrialized crushing processes, the disposal of wind turbine blades has certain requirements, and there are related downstream demands and applications. Wind turbine blades are made of materials such as long fiber composites, glass fiber composites, and carbon fiber composites. These materials are high in strength, lightweight, and the blades are very tough, making them difficult to disassemble using conventional equipment.
[0006] Currently, a large number of discarded wind turbine blades are dismantled on-site into unit blocks of a certain size using manual hand-held cutting saws and excavator rock saws. These unit blocks are then collected and transported by specialized vehicles to professional processing plants for further processing, such as mechanical crushing, pyrolysis, pulverization, and reuse.
[0007] Mechanical cutting generates a large amount of harmful dust (glass fiber and carbon fiber debris), posing a serious threat to the health of operators, causing secondary pollution to the surrounding atmosphere and soil, and producing significant noise pollution. The high temperatures generated by the friction between the saw blade and the material can damage the material structure, hindering subsequent recycling and disposal. Furthermore, it introduces safety risks during construction and does not comply with HSE standards. Relevant departments have clearly stated their intention to gradually phase out this treatment method, necessitating a new, highly automated, and intelligent device and treatment method that meets HSE standards. Summary of the Invention
[0008] The present invention aims to address the shortcomings of the prior art by providing a water-cutting robot device and water-cutting process method for waste wind turbine blades.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:

The industrial robot system has a containerized structure, including two industrial robots, a container, and a monitoring device. The two industrial robots are mounted longitudinally facing each other on a skid at the bottom of the container. One end of the folding track of the blade translation system is connected to the skid of the industrial robot system. The water-jet cutting system is installed on the right side of the industrial robot system, and the cutting nozzle of the water-jet cutting system is fixed on the end of the industrial robot arm.

The generator set is installed on the left side of the industrial robot system to provide power to all equipment. The control system controls the blade translation system, the water-jet cutting system, and the circulating water treatment system to work together through a PLC controller.
[0011] The industrial robot system described above uses an IP67 standard waterproof six-axis cleaning robot with a waterproof cover. Visual cameras are installed at the end of the robot arm and on both sides. The front and rear sides of the industrial robot system are connected to the top surface, and the sides can be opened and closed by rotation. The two sides and the top cover are supported by telescopic support columns.
[0012] The waterjet cutting system is a containerized structure, including an ultra-high pressure plunger pump assembly, an abrasive system, a cutting nozzle, a safety monitoring device, and a waterjet cutting control system installed inside the container.

[0015] A waterjet cutting process for waste wind turbine blades, utilizing a waterjet cutting robot device for waste wind turbine blades, comprises the following steps:
[0016] S1. Waterjet cutting robot installation: Install and position the industrial robot system and blade translation system, install the waterjet cutting system, circulating water treatment system and generator set, and then connect the circuit and water pipes;
[0017] S2. Blade positioning: At the construction site, a crane lifts and places the blade onto three blade support groups and fixes it firmly. The blade with the suction surface SS facing upwards is placed horizontally on the blade support. The V-shaped traveling support is adjusted to move the blade to the initial cutting position. Two robots are positioned on the side of the leading edge and trailing edge of the blade, respectively, according to the set positions. The industrial robot located at the leading edge of the blade is called R1, and the industrial robot located at the trailing edge of the blade is called R2.
[0018] S3. Preset cutting path: The cutting path program of the cutting nozzle is preset by the control system. According to the shape curve size of the blade, the corresponding cutting size and process are determined. The cross-sectional curve of each segment of the blade is different. The cutting path of each cutting segment is compiled by the teach pendant programmer and combined with the actual working state. That is, the cutting process obtained by the first actual cutting is first stored in the PLC controller as the original program, and then the corresponding program is selected according to the segment for cutting.
[0019] S4. Cutting Process: First, the blade translation system moves the blade to the first cutting position and locks it. The cutting nozzle at the end of the industrial robot arm moves from its original position to the starting point of the cutting segment, calibrates and positions itself, selects the corresponding first cutting program, and runs according to the predetermined program to cut the first segment. To cut the second segment, the blade translation system moves the blade to the second cutting position and locks it. The cutting nozzle at the end of the industrial robot arm moves from its original position to the starting point of the cutting segment, calibrates and positions itself, selects the second cutting program, and cuts the second segment. This process is repeated, with each segment having a different cutting path and number of cuts.

Install and lock them firmly to determine the positioning reference for the installation of the entire device.
[0022] P2. Blade translation system installation and positioning: Connect one end of the folding track of the blade translation system to the skid in the industrial robot system box with a V-block and quickly connect and position it with a pin. Adjust to keep the folding track vertical to the skid in the industrial robot system box, and adjust to ensure that the track surface is horizontal. Install the three supports of the blade support group in the set position.
[0023] P3. Installation of waterjet cutting system, circulating water treatment system and generator set: Install the waterjet cutting system in the designated position on the right side of the industrial robot system, install the circulating water treatment system in the designated position on the right side of the waterjet cutting system, and install the generator set in the designated position on the left side of the industrial robot system.

[0026] In step S4, when cutting the blade, the cutting nozzles at the ends of the two industrial robot arms are controlled to maintain two postures: "horizontal cutting" and "vertical cutting". "Horizontal cutting" means that the water jet from the cutting nozzle is in a horizontal plane, and "vertical cutting" means that the water jet from the cutting nozzle is in a vertical plane. When cutting the blade, the direction along the blade length is longitudinal, and the direction perpendicular to the blade length is transverse.

[0064] S2. Blade positioning: At the construction site, a crane lifts and places the blade onto three blade support groups and fixes it firmly. The blade with the suction surface SS facing upwards is placed horizontally on the blade support. The V-shaped traveling support is adjusted to move the blade to the initial cutting position. Two robots are positioned on the side of the leading edge and trailing edge of the blade, respectively, according to the set positions. The industrial robot located at the leading edge of the blade is called R1, and the industrial robot located at the trailing edge of the blade is called R2.
[0065] S3. Preset cutting path: The cutting path program of the cutting nozzle is preset by the control system 6. According to the shape curve size of the blade, the corresponding cutting size and process are determined. The cross-sectional curve of each blade segment is different. The cutting path of each cutting segment is compiled by the teach pendant programmer and combined with the actual working state. That is, the cutting process obtained by the first actual cutting is first stored in the PLC controller as the original program, and then the corresponding program is selected according to the segment for cutting.
[0066] S4. Cutting Process: First, the blade translation system 5 moves the blade to the first cutting position and locks it. The cutting nozzle at the end of the industrial robot arm moves from its original position to the starting point of the cutting segment, calibrates and positions itself, selects the corresponding first cutting program, and runs according to the predetermined program to cut the first segment. To cut the second segment, the blade translation system 5 moves the blade to the second cutting position and locks it. The cutting nozzle at the end of the industrial robot arm moves from its original position to the starting point of the cutting segment, calibrates and positions itself, selects the second cutting program, and cuts the second segment. This process is repeated, with each segment having a different cutting path and number of cuts.
[0067] The specific steps for installing the waterjet cutting robot are as follows:
[0068] P1. Industrial robot system positioning: Install the industrial robot system 2 in the predetermined position and adjust the horizontal positioning.

R2 cuts a "U" shaped trajectory, cutting out a piece of the upper right shell, which is numbered 02-02.
[0078] b. R1 cuts longitudinally from the cross-section along the left edge of the lower beam cap, i.e., the line where the lower beam cap intersects with the lower left shell, to the leaf root to the second cutting surface, and then laterally to the front edge. R1 cuts an "L" shaped trajectory, cutting out a piece of the lower left shell, which is numbered 02-03.
[0079] At the same time, R2 cuts longitudinally from the cross-section along the right edge of the lower beam cap, that is, the intersection line of the lower beam cap and the lower right shell, to the leaf root to the second cutting surface, and then transversely to the rear edge. R2 cuts an "L" shaped trajectory, cutting out a piece of the lower right shell, which is numbered 02-04.
[0080] c.

The cutting process for the third, fourth, fifth, and sixth segments is the same as that for the second segment. The seventh segment is cut at a point 3 1 / 75 degrees from the origin, with the leaf root as the origin. The cutting process for the seventh segment is as follows: A.R1 cuts longitudinally from the left edge of the upper beam cap along the cross-section, i.e., the line where the upper beam cap intersects with the upper left shell, to the leaf root to the second cutting surface, then transversely to the front edge and cuts vertically, then cuts horizontally along the front edge to the cross-section. R1 cuts a "U" shaped trajectory, cutting out a piece of the upper left shell, numbered 07-01. At the same time, R2 cuts longitudinally from the cross-section along the right edge of the upper beam cap, that is, the line where the upper beam cap intersects with the upper right shell, to the leaf root, then laterally to the middle of the upper right shell, and then longitudinally to the cross-section to cut vertically. R2 cuts a "U" shaped trajectory, cutting out the first piece of the upper right shell, numbered 07-02. R2 cuts the remaining upper right shell longitudinally from the rear edge of the cross-section to the cutting surface, and then cuts it horizontally and vertically along the cutting surface. R2 cuts an "L" shaped trajectory to cut out the second piece of the upper right shell, numbered 07-03. B.R1 cuts longitudinally from the left edge of the lower beam cap along the cross section, i.e., the line where the lower beam cap intersects with the lower left shell, to the leaf root, then laterally to the front edge, cutting in an "L" shaped trajectory, cutting out a piece of the lower left shell, numbered 07-04; At the same time, R2 cuts longitudinally from the middle of the lower right shell section to the blade root to the cutting surface, and then laterally to the trailing edge. R2 cuts an "L" shaped trajectory, cutting out the first piece of the lower right shell, numbered 07-05. R2 runs longitudinally from the cross-section along the right edge of the lower beam cap (the intersection line between the lower beam cap and the lower right shell) towards the leaf root to the cutting surface, and then cuts the remaining lower right shell horizontally and vertically. R2 cuts an "L" shaped trajectory to cut out the second piece of the lower right shell, numbered 07-06. C.R1 cuts longitudinally from the cross-section along the intersection line of the left shear web and the lower beam cap towards the leaf root to the cutting surface, then cuts horizontally upwards along the left shear web to the upper beam cap, and vertically cuts the upper beam cap. R1 cuts an "L" shaped trajectory. At the same time, R2 cuts longitudinally from the cross-section along the intersection line of the right shear web and the lower beam cap towards the leaf root to the cutting surface, then cuts horizontally upwards along the right shear web to the upper beam cap. R1 cuts an "L" shaped trajectory, cutting out the "∏" shaped connection between the shear web and the upper beam cap, numbered 07-07. D.R1 cuts from the left side of the lower beam cap along the cutting surface to the middle of the lower beam cap, and R2 cuts perpendicularly from the middle of the lower beam cap along the cutting surface to the right side of the lower beam cap. The straight lines of R1 and R2 are used to cut out the lower beam cap segments, numbered 07-08. The eighth, ninth, and tenth segments are cut at positions 24 / 75, 17 / 75, and 12 / 75 of the origin from the leaf root, respectively. The cutting process for the eighth, ninth, and tenth segments is the same as that for the seventh segment. The eleventh segment is cut on the blade at a distance of 7 / 75 from the origin with the blade root as the origin. The eleventh segment cutting process is as follows: R1 and R2 cut longitudinally from the cross-section along the outer circle to the blade root, and then cut horizontally and vertically along the outer circle to cut out 6 equal pieces. The cutting trajectory is "L" shaped and numbered as 11-01 / 02 / 03 / 04 / 05 / 06 respectively. The twelfth segment is cut on the blade at a position 2 / 75 of the distance from the origin, with the leaf root as the origin. The cutting process for the twelfth segment is the same as that for the eleventh segment. The thirteenth section is cut at the leaf root. The leaf root cutting process is as follows: 1) Cut the inner circular reinforcing plate of the leaf root: R1 and R2 are cut horizontally, and the "1 / 4 circular fan-shaped" trajectory is cut. Two 1 / 4 fan-shaped pieces are cut respectively, numbered 13-01 / 02 / 03 / 04. 2) Cutting the leaf root body: R1 and R2 cut the leaf root tail longitudinally along the outer circle from the cross-section, cut 3 times each, and cut 6 equal pieces, numbered 13-05 / 06 / 07 / 08 / 09 / 10.
