Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and more specifically, to a cutting method for the tip joint of a blade. Background Art

[0002] Due to environmental factors such as wind, rain erosion, and sun exposure, the blades of wind power generators will be forced to retire after a certain period of use. In addition, due to the expansion of single wind turbines caused by technological progress, more and more wind turbine blades are facing the problems of post-retirement treatment and reuse. Since 2000, the number of retired wind turbine blades has been increasing year by year. Conservatively estimated, by 2040, a total of about 27,000 wind turbines will face retirement, and 6.58 million tons of blades need to be processed. Wind turbine blades are mainly composed of materials such as fiberglass or carbon fiber, epoxy resin, and balsa wood. Currently, the common treatment methods for wind turbine blades are landfill or incineration, which will cause great harm to human life and the environment. Wind turbine blades should be sawed by special cutting tools and cutting equipment to achieve the recycling and value-added comprehensive utilization of retired wind turbine blades.

[0003] Wind turbine blades can be roughly divided into four parts by structure: main beam, blade root, web, and skin. The main beam (the skeleton of the wind turbine blade) is composed of fiber-reinforced composite materials, with high mechanical strength, waterproof, wear-resistant, corrosion-resistant, and good durability. After retirement, the blade still retains 95% of its initial mechanical properties (the static bending strength parallel to the fiberglass cloth direction is about 1000 MPa), and its mechanical strength is much higher than that of materials such as wood. The blade root is composed of fiber-reinforced composite materials and has prefabricated bolt holes. The web is mainly composed of lightweight materials such as balsa wood or PVC foam, and has good heat preservation, sound insulation, and shock absorption effects. The skin is a sandwich structure composed of a surface fiber-reinforced composite material and an internal core material (such as balsa wood, PVC foam material, etc.), as Figure 1 shown. The tip is the thinnest part of the wind turbine blade in terms of material thickness. The force at the tip has a great influence on the performance of the entire wind turbine. The structural strength is mainly provided by a layer of skin material on the surface and the web in the middle. The skin is reinforced by a biaxial composite material layer, which provides the aerodynamic shape and bears most of the shear loads.

[0004] In the existing technologies for dividing and utilizing blades, the tip is first cut off by a transverse cutting device, then divided into multiple smaller sheet materials, and then broken and incinerated or landfilled, which causes great pollution to the environment and fails to utilize the originally excellent properties of the waste wind turbine blade materials. The material utilization rate is low, and the original properties of the materials are damaged after the crushing treatment. Therefore, how to process the tip of the waste wind turbine blade into reusable sheet materials and increase the material utilization rate of the tip part of the waste wind turbine blade is the technical problem to be solved by the present invention. Summary of the Invention

Detailed implementation mode

[0047] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0048] It should be understood that terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0049] The present invention provides a cutting method for the tip mold clamping area, including the following steps:

[0050] S1: Preparation work before processing. By visually inspecting the cross-section, find the mold joint of the leading edge of the blade tip (the windward side of the wind turbine blade, where the wind flows in from the leading edge, with a smooth surface and relatively larger width and thickness compared to the trailing edge) and the trailing edge (the leeward side of the wind turbine blade, where the wind flows out from the trailing edge, with a flat and elongated shape). Since wind turbine blades are huge in size, they are usually manufactured by an assembly method. First, the blade main beam, web, and other components are separately formed on a special mold, and then on the main mold, two shells, the web, and other components are glued and assembled together with an adhesive. After the mold joint is pressurized and cured, the integral blade is formed. The adhesive at the mold joint is very brittle after curing and is easy to cut), as Figure 2 shown, check whether there are metal parts such as sensors inside the blade tip. If there are metal parts, perform step S2; if there are no metal parts, perform step S3;

[0051] S2: Remove the removable metal parts, and mark the non-removable metal parts. Pay attention to avoiding them during cutting to prevent safety accidents;

[0052] S3: Draw the cutting route 3. Use the marking device 2 to draw the cutting route 3 of the cutting device on the surface of the blade tip. The marking device 2 moves along the edge of the adhesive material 1 at the mold joint inside the blade tip, as Figure 3 shown. Thus, when the cutting device cuts, it cuts along the edge of the adhesive material 1 at the mold joint inside the blade tip, which can avoid cutting the adhesive material 1 at the mold joint, reduce the wear of the cutting tool of the cutting device, and prevent safety accidents caused by the flying of the adhesive material during cutting. The cutting route 3 does not pass through the non-removable metal parts to avoid damage to the cutting tool of the cutting device and prevent safety accidents at the same time;

[0053] S4: Cut the two half-surfaces of the blade tip along the cutting route 3 with a cutting device to obtain blank A and blank B. Before the cutting device cuts the blade tip, place the blade tip on the ground, an operating platform, or the cutting device, or place it in the processing position. The specific placement position can be selected according to the cutting device and the cutting method. For example, when using a hand saw, the blade tip can be placed on the ground, as Figure 2 shown. First, cut the top surface, and then turn it over to cut the bottom surface. When the cutting device cuts the blade tip, the half-surface on the upper side of the blade tip is half-surface A, and the half-surface on the lower side is half-surface B. The cutting device is a handheld device or a non-handheld device with a sawing tool. The cutting device is not limited to any form of cutting method such as a handheld cutting device, a wire saw, a water jet cutting, a thermal cutting, a pneumatic cutting, etc. The sawing tool is a saw blade or a milling cutter. The sawing tool is not limited to diamond alloy circular saw blades, diamond milling cutters, diamond-free abrasive saw blades, etc.;

[0054] S5: After taking out the blanks (the relatively flat main beam materials cut from the blade tip), blank A and blank B can be disassembled and packed according to the size on-site to facilitate the subsequent transportation of the blanks.

[0055] Working principle and beneficial effects of the above technical solution: Through the design of the above structure, the blade tip is segmented from the blade tip mold closing position, and two complete upper and lower surfaces of the blade tip can be obtained. The waste that needs to be broken, buried or incinerated in the prior art is further subjected to material extraction and processed into reusable sheet materials, improving the subsequent processability of the blade tip material, reducing material waste, increasing the material utilization rate of the blade tip part of the waste wind power blade. After the sheet material is decomposed into parts of different sizes, the performance of the original fiber-reinforced composite material can still be retained to the greatest extent, so as to realize the high-value recycling and reuse of the blade tip part of the waste wind power blade.

[0056] In this embodiment, step S4 includes multiple implementation manners, and the specific implementation manners can be selected according to the differences of the cutting equipment and the cutting depth. The implementation manners of step S4 include:

[0057] Manner 1: First, separate the sheet material A from the half surface A of the blade tip, and without flipping the blade tip, separate the sheet material B from the half surface B of the blade tip. The specific steps are as follows:

[0058] S411: Cut the half surface A of the blade tip to obtain the sheet material A, and separate the sheet material A from the blade tip;

[0059] S412: Cut the half surface B of the blade tip to obtain the sheet material B, and separate the sheet material B from the blade tip.

[0060] Manner 2: First, separate the sheet material A from the half surface A of the blade tip, and after flipping the blade tip through the hoisting equipment, then separate the sheet material B from the half surface B of the blade tip. The specific steps are as follows:

[0061] S421: Cut the half surface A of the blade tip to obtain the sheet material A, and separate the sheet material A from the blade tip;

[0062] S422: Flip the blade tip through the hoisting equipment to flip the half surface B of the blade tip to the top;

[0063] S423: Cut the half surface B flipped to the top to obtain the sheet material B, and separate the sheet material B from the blade tip.

[0064] Manner 3: Use the cutting equipment to cut the half surface A and the half surface B simultaneously, and separate the two sheet materials at one time. The specific steps are as follows:

[0065] S431: Cut the half surface A and the half surface B of the blade tip simultaneously;

[0066] S432: Separate and obtain the sheet material A and the sheet material B at one time, and separate the sheet material A and the sheet material B from the blade tip.

[0067] In the foregoing embodiments, we mentioned that when the cutting device performs cutting, it is necessary to avoid the bonding material 1 at the mold clamping position as much as possible. Although it is very brittle after curing and easy to cut, cutting the bonding material 1 at the mold clamping position will accelerate the wear of the cutting tool. At the same time, the flying bonding material 1 at the mold clamping position poses a potential safety hazard. In addition, as Figure 2 shown, the bonding material 1 at the mold clamping position at the trailing edge is relatively thick. If it is cut unidirectionally, a part of the cut plate is still connected to the bonding material 1 at the mold clamping position, which is not convenient to take out the plate. Therefore, during the cutting process, it is usually cut along the edge of the bonding material 1 at the mold clamping position, and the bonding material 1 at the mold clamping position is avoided from being cut when not necessary. Because the edge positions of the bonding material 1 at the mold clamping position of each blade tip are different, and the gap inside the blade tip is narrow and inconvenient to observe. If it is directly cut by feeling, in addition to causing material waste (the cutting position is far from the edge of the bonding material at the mold clamping position), it also depends on personal experience, and the sizes of the cut plates vary greatly. Therefore, when drawing the cutting route 3, a special marking device 2 is used to move along the edge of the bonding material 1 inside the blade tip and the place with the smallest vertical distance at the leading edge, and project the inner edge onto the half-plane A and the half-plane B. At the same time, a distance needs to be left between the cutting route 3 projected on the half-plane A and the half-plane B and the inner contour as a tolerance distance. To achieve the above technical effects, we provide a marking device 2 suitable for this cutting method.

[0068] In this embodiment, the marking device 2 is composed of an internal walking device 4 and an external marking device 5. The internal walking device 4 is located inside the blade tip, and the external marking device 5 is located outside the blade tip and above the upper surface of the blade tip (half-plane A or the flipped half-plane B). The internal walking device 4 and the external marking device 5 are connected by a link mechanism 6, and the link mechanism 6 is used to synchronously move the internal walking device 4 and the external marking device 5.

[0069] Before marking the cutting route, first assemble the marking device 2 and install the internal walking device 4 and the external marking device 5 on the link mechanism 6. When in use, place the internal walking device 4 inside the blade tip and make it adhere to the edge of the bonding material 1 at the trailing edge of the mold clamping position (or the place with the smallest vertical distance at the leading edge). At this time, the external marking device 5 adheres to and presses on the upper surface of the blade tip and applies a certain pressure to the upper surface. Push the link mechanism 6 to make the internal walking device 4 move along the inner contour of the blade tip. During the movement of the internal walking device 4, the external marking device 5 will slide on the upper surface of the blade tip and form a scratch (or a marking line). Then take out the marking device 2 and cut along the scratch (or the marking line).

[0070] Further, to facilitate the assembly of the marking device 2 into the storage box, the link mechanism 6 is generally composed of two parallel brackets (the first bracket 61 and the second bracket 62), and a mounting bracket 63 hinged to the two brackets. One end of the first bracket 61 is detachably connected to the internal traveling device 4, and the other end is hinged to the bottom of the mounting bracket 63. One end of the second bracket 62 is detachably connected to the external marking device 5, and the other end is hinged to the top of the mounting bracket 63. Generally, the first bracket 61 and the second bracket 62 are triangular brackets, which can provide good stability. And during the process of drawing the cutting route 3, it can avoid the first bracket 61 touching the bonding material 1 at the mold clamping position (or the place with the smallest vertical distance between the leading edges), thereby preventing the first bracket 61 from getting stuck in the gap during movement. The mounting bracket 63 is a rectangular bracket, and during the process of drawing the cutting route 3, the mounting bracket 63 is always located outside the leaf tip, and there is always a distance d between the bottom surface of the second bracket and the outer surface (half plane A) of the leaf tip to ensure that it will not affect the movement of the external marking device 5.

[0071] When the marking device 2 is not in use, the first bracket 61 and the second bracket 62 can rotate relative to the mounting bracket 63 and be folded, thus facilitating storage and reducing the volume of the marking device 2. When using the marking device 2, just flip the first bracket 61 and the second bracket 62 to open them. Since the internal traveling device 4 is placed on the inner bottom surface (half plane B) of the leaf tip, and the external marking device 5 is pressed on the outer surface (half plane A) of the leaf tip, and both have supports in the vertical direction, the link mechanism 6 only needs to be responsible for the synchronous transmission of the horizontal position. Therefore, generally, the first bracket 61 and the second bracket 62 are hinged to the mounting bracket 63 through screws with wrenches. After adjusting the positions of the first bracket 61 and the second bracket 62, the screws with wrenches can be directly tightened to fix the positions of the first bracket 61 and the second bracket 62.

[0072] Further, the internal walking device 4 is composed of a ball wheel assembly 41, a roller assembly 42, and a mounting sleeve 43. The outer wall of the mounting sleeve 43 is detachably connected to the first bracket 61. The ball wheel assembly 41 is disposed within the mounting sleeve 43, and the roller assembly 42 is disposed at the top of the mounting sleeve 43 and above the ball wheel assembly 41. When using the marking device 2, first connect the mounting sleeve 43 and the first bracket 61 with screws, or a snap structure for detachable connection can be provided on the mounting sleeve 43 and the first bracket 61, as long as the detachable connection between the two can be achieved. During use, the ball wheel assembly 41 is located on the inner bottom surface of the blade tip (half plane B) and can translate 360 degrees horizontally without dead angle on the inner bottom surface of the blade tip (half plane B), so that the internal walking device 4 can change the moving direction arbitrarily when moving. The roller assembly 42 abuts against the edge of the bonding material 1 at the mold closing position (or the place with the smallest vertical distance between the upper and lower leading edges), thereby changing the direction of the internal walking device 4. Usually, the roller assembly 42 is an optional component. The internal walking device 4 can be without the roller assembly 42, and the projection of the inner contour can still be achieved only relying on the ball wheel assembly 41. It should be noted that if the roller assembly 42 is not provided, the projection is the actual edge of the inner contour without a tolerance distance, and it is necessary to manually control away from the actual edge of the projection during cutting to avoid cutting the bonding material 1 at the mold closing position. After the roller assembly 42 is provided, the projection is the cutting route 3 of the inner contour, and this cutting route has a tolerance distance, which can effectively avoid cutting the bonding material 1 at the mold closing position and ensure the consistency of the size of the cut plate.

[0073] Further, the mounting housing 43 is composed of a lower housing 431 and an upper housing 432. The ball wheel assembly 41 is arranged between the lower housing 431 and the upper housing 432. The roller assembly 42 is arranged on the top of the upper housing 432. The ball wheel assembly 41 is composed of a ball 411 and a limiting member 412. The limiting member 412 is arranged in a groove at the bottom of the upper housing 432. A first ball groove adapted to the diameter of the ball 411 is arranged on the bottom surface of the limiting member 412. The ball 411 is located in the first ball groove and is movably connected to the first ball groove through an annular friction pair 413. The ball 411 can rotate relative to the friction pair 413. A second ball groove adapted to the diameter of the ball 411 is arranged on the top surface of the lower housing 431. An opening is arranged on the bottom surface of the lower housing 431, and the diameter of the opening is smaller than the diameter of the ball 411. After the upper housing 432 and the lower housing 431 are connected by screws, the bottom of the ball 411 extends to the outside of the lower housing 431 through the opening. The roller assembly 42 is composed of a roller 421 and a first rotating shaft 422. The first rotating shaft 422 is arranged vertically on the top of the upper housing 432. The roller 421 is arranged on the first rotating shaft 422 and is movably connected to the first rotating shaft 422. Thus, the internal traveling device 4 can be translated on a horizontal plane through the ball 411. The marking point of the external marking device 5 and the first rotating shaft 422 are located on the same central axis. The radius of the roller 421 is used to form the error tolerance distance of the cutting route 3.

[0074] Further, the external marking device 5 is composed of a reset member 51, a transmission rod 52, a fixing member 55 and a marking tool 56. The transmission rod 52 is an L-shaped structure composed of a reset rod 521 and a pressure rod 522. A second rotating shaft 53 is provided at the connection between the reset rod 521 and the pressure rod 522. A detachable shaft seat 54 is provided on the second bracket 62. The transmission rod 52 is movably connected to the shaft seat 54 of the second bracket 62 through the second rotating shaft 53. The reset rod 521 is arranged in the vertical direction and extends away from the second bracket 62 through the second rotating shaft 53. One end of the reset rod 521 away from the second rotating shaft 53 is connected to the second bracket 62 through the reset member 51. The reset member 51 can be a pneumatic structure, a hydraulic mechanism or a spring structure. Under the action of the reset member 51, the reset rod 521 always has a tendency to rotate towards the pressure rod 522 with the second rotating shaft 53 as the rotation axis. The pressure rod 522 is arranged in the horizontal direction and extends away from the second bracket 62 through the second rotating shaft 53. The fixing member 55 is detachably arranged at one end of the pressure rod 522 away from the second rotating shaft 53. The marking tool 56 is detachably connected to the fixing member 55. Usually, the cross-section of the fixing member 55 is T-shaped. The flat end is composed of two planes with grooves. After the two planes are buckled, a hole for accommodating the marking tool 56 is formed. The two planes are connected by screws to fix the marking tool 56. The T-shaped protruding part is a square plate-like structure and is connected to the pressure rod 522 by screws, as Figure 11 shown. The marking tool 56 can be a scratching tool or a drawing tool, such as a metal rod inlaid with diamond, or a marker pen.

[0075] When assembling the external marking device 5, the shaft seat 54 is installed on the second bracket 62, one end of the reset member 51 is movably connected to the second bracket 62 (usually shaft connection), and the marking tool 56 is installed on the fixing member 55. Then, the second rotating shaft 53 is movably connected to the shaft seat 54, and the fixing member 55 installed with the marking tool 56 is installed at the end of the pressure rod 522 (adjust the installation direction of the fixing member 55 according to the on-site requirements. For example, when marking the cutting route 3, make the scratching end or the drawing end of the marking tool 56 face the direction of the first bracket 61. Usually, the marking tool 56 is arranged in the vertical direction, as Figure 10 shown in A of Figure 11 and Figure 10 shown in A of Figure 11As shown in Figure B, a groove for accommodating the scratch end or the marking end is provided at the end of the second bracket 62. Under the action of the reset member 51, the scratch end or the marking end of the marking tool 56 will be located within the groove to avoid being knocked. Finally, the other end of the reset member 51 is movably connected to the end of the reset rod 521 (usually a shaft connection) to provide pressure for the marking tool 56, so as to ensure that the marking tool 56 can always closely adhere to the surface of the leaf tip.
