Description

Technical Field

[0001] The invention relates to the technical field of wind turbine blade bonding, and in particular to a carbon fiber wind turbine blade bonding adhesive coating device. Background Art

[0002] Wind turbine blades are large in size and are often manufactured using two half molds, which are then bonded together to form a complete blade. Good bonding between the two half molds is the key to ensuring the structural integrity and performance of the blades. If the bonding between the half molds is not strong, it may cause serious problems such as cracks, delamination, or even breakage in the blades, affecting the service life and power generation efficiency of the blades.

[0003] When applying adhesive to the half molds of wind turbine blades, it is generally done manually. The operator uses simple tools, such as brushes and scrapers, to apply the adhesive to the connection between the two half molds. Manual glue application may require multiple applications to allow the glue to completely cover the glue application area. Multiple applications are difficult to ensure that the thickness is completely matched with the first application, especially in the case of manual operation. This will make the thickness of the glue layer uneven and may form an overly thick glue layer in local areas. An overly thick glue layer will generate greater internal stress during the curing process, increasing the risk of cracking the glue layer and affecting the closing accuracy of the two half molds.

[0004] To this end, the present invention proposes a carbon fiber wind turbine blade adhesive coating device. Summary of the invention

[0015] This device can avoid the situation of multiple coatings, ensure that the glue layer is formed at one time, make the combination inside the glue layer closer, reduce the problem of poor interlayer combination caused by multiple coatings, which helps to improve the delamination resistance of the wind power blade during operation, and ensure that the glue layer can still maintain good bonding performance under the condition that the blade bears complex external forces for a long time;

[0016] By means of the dust suction hood, the dust and impurities on the closing surface at the front end of the electric runner movement are sucked in, which can provide a cleaner and purer attachment surface for the bonding glue. The bonding glue can directly contact the surface of the closing surface of the wind power blade half mold, effectively improving the bonding effect of the glue and making the bonding between the wind power blade half molds more firm;

[0017] By scraping the bonding glue on the closing surface of the wind power blade half mold with the glue scraping plate, the surface of the already coated bonding glue becomes smoother, the thickness of the glue layer is uniform, and the overall quality of the bonding glue is improved. When the two wind power blade half molds are closed, the smooth glue layer can better fit the surface of the wind power blade half mold, reduce the gap, the scraped glue layer closely adheres to the two closed wind power blade half molds, enhancing the bonding stability and reducing the possibility of problems such as delamination and glue peeling during the use of the blade.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiments provided by the present invention:

[0037] Embodiment 1 of the present invention:

[0038] like Figure 1 As shown, a carbon fiber wind turbine blade adhesive coating device is applied to a wind turbine blade half mold 1. The wind turbine blade half mold 1 is an existing known structure. The wind turbine blade half mold 1 is partially displayed in the figure. The top surface of the wind turbine blade half mold 1 is a closing surface that needs to be coated with glue, hereinafter referred to as the closing surface. The existing wind turbine blade half mold 1 has two closing surfaces, only one of which is shown in the figure. The wind turbine blade half mold 1 includes a thicker end a and a narrower end b, and the end a gradually shrinks to the end b. The wind turbine blade half mold 1 shown in the figure is scaled down in order to show the winding surface characteristics.

[0039] like Figures 1 to 7As shown, a carbon fiber wind turbine blade adhesive coating device includes a coating adaptive component that adaptively adjusts the coating path and area according to the winding curved surface of the wind turbine blade half mold 1, and the coating adaptive component includes a guide square column 25, two support plates 24 are slidably arranged on the guide square column 25, and the bottom of the two support plates 24 are rotatably connected to a coupling block 23, and a rotating shaft 21 is fixedly arranged in the middle of the coupling block 23. The top and bottom ends of the rotating shaft 21 are rotatably connected to an electric wheel 22, and the four electric wheels 22 are electrically connected to an external controller. A spring 26 is arranged between the two support plates 24, and the spring 26 is sleeved on the outside of the guide square column 25. Each coupling block 23 is fixedly connected to two symmetrically arranged side blocks 27, and the side blocks 27 are rotatably connected to a telescopic circular tube 28. The telescopic circular tube 28 includes a mounting end and a telescopic end, and the mounting end of the telescopic circular tube 28 passes through the side block 27 and is connected to the side block 27 is rotatably connected, the telescopic end of the telescopic circular tube 28 is fixedly connected with a wheel frame 29, and an auxiliary wheel 210 is rotatably connected inside the wheel frame 29, a spring 211 is connected between the mounting end and the telescopic end of the telescopic circular tube 28, and an auxiliary wheel torsion spring 212 is connected between the mounting end of the telescopic circular tube 28 and the side block 27, and a guide square column 214 is slidably connected to each of the two support plates 24, and a glue storage box 213 is fixedly connected to one end of the two guide square columns 214 close to each other, and a plurality of glue leakage holes 215 are evenly opened on the bottom surface of the glue storage box 213, and a filling pipe is provided on the top surface of the glue storage box 213, and a filling cap 216 is clamped on the filling pipe of the glue storage box 213, and a leakage shielding plate 217 is fixedly connected to the side of the two support plates 24 close to each other, and the two leakage shielding plates 217 are both slidably connected to the outer wall side of the glue storage box 213, and the two leakage shielding plates 217 are both in contact with the bottom surface of the glue storage box 213.

[0040] like Figure 3 , Figure 6 , Figure 8 As shown, an elastic torsion spring is arranged between the coupling block 23 and the adjacent support plate 24. Specifically, when the electric wheel 22 moves, the elastic torsion spring is in an elastic deformation state, so that the electric wheel 22 remains in contact with the wind turbine blade half mold 1, thereby adapting to the curved shape of the side wall of the wind turbine blade half mold 1.

[0041] Specifically: the electric wheel 22 and the auxiliary wheel 210 on the same side form a three-point positioning for the side wall of the wind turbine blade half mold 1, and the electric wheel 22 is always in contact with the side wall of the wind turbine blade half mold 1 through the force of the elastic torsion spring, and the auxiliary wheels 210 on both sides are always in contact with the side wall of the wind turbine blade half mold 1 through the force of the auxiliary wheel torsion spring 212;

[0042] When the electric wheel 22 moves forward to the curved raised portion, due to the rotational connection between the coupling block 23 and the support plate 24, the coupling block 23 will rotate to adjust the position of the electric wheel 22 to fit the raised portion. At the same time, the force of the elastic torsion spring ensures that the electric wheel 22 is in close contact with the raised portion and will not come off.

[0043] As above, when the auxiliary wheels 210 on both sides encounter the raised parts, the telescopic tube 28 will rotate on the side block 27 , and the auxiliary wheel torsion spring 212 ensures that the auxiliary wheel 210 is tightly fitted with the wind turbine blade half mold 1 .

[0044] At the same time, since the electric wheel 22 on the same side and the auxiliary wheels 210 distributed on both sides thereof are three independent individuals, that is, when encountering a raised portion, the three wheels pass through in sequence. Therefore, the three wheels on the same side can adapt to the shape changes of the side wall of the wind turbine blade half mold 1 in sequence, and at the same time, the three wheels can move continuously along the curved and undulating side wall of the wind turbine blade half mold 1.

[0045] like Figure 3 As shown, a suspended plate is provided at a position offset from the glue leakage hole 215 at the bottom of the glue storage box 213. The suspended plate is used to contact the closing surface of the wind turbine blade half mold 1, so that a gap is exposed between the glue leakage hole 215 and the closing surface. The suspended plate is provided at the bottom center of the glue storage box 213.

[0046] like Figure 3 As shown, the two ends of the two leakage shielding plates 217 close to each other are each provided with a rubber block, which is used to fit the curved surfaces of the inner and outer walls of the wind turbine blade half mold 1 to ensure that the leakage hole 215 is not blocked by the leakage shielding plate 217. The leakage portion corresponds to the width of the closed surface of the wind turbine blade half mold 1 at this time.

[0047] Here, the coating of adhesive from end a to end b of the wind turbine blade half mold 1 is taken as an example.

[0048] When in use, the user pulls the two support plates 24 to both sides, so that the spring 1 26 is elastically stretched, and the two support plates 24 move away from each other on the guide square column 1 25, and the two support plates 24 drive the two coupling blocks 23 and the two leakage shielding plates 217 to move away from each other synchronously. At this time, the user places the two support plates 24 on the inner and outer sides of the end a of the wind turbine blade half mold 1 respectively, and then stops pulling the two support plates 24. At this time, under the action of the elastic contraction of the spring 1 26, the two support plates 24 slide toward each other on the guide square column 1 25, and drive the two sets of electric wheels 22 to move synchronously, so that the two sets of electric wheels 22 respectively contact the wind turbine blade half mold 1 On the inner and outer walls, one end of the two leakage shielding plates 217 that is close to each other, that is, the rubber block, is in contact with the inner and outer walls of the wind turbine blade half mold 1, and the four auxiliary wheels 210 are also in contact with the side walls of the wind turbine blade half mold 1. Since the side walls of the wind turbine blade half mold 1 are curved surfaces, the four auxiliary wheels 210 in contact with the side walls are subjected to different pressures according to the different curvatures of the side walls of the wind turbine blade half mold 1, and the corresponding telescopic ends of the telescopic tubes 28 on each auxiliary wheel 210 are subjected to different pressures, so that the spring 211 and the auxiliary wheel torsion spring 212 are both elastically deformed. The auxiliary wheels 210 are provided to improve the stability of the overall device when it moves.

[0049] The user then fills the glue storage box 213 with adhesive, and then starts the four electric wheels 22. The rotation of the electric wheels 22 will generate friction with the side walls of the wind turbine blade half mold 1, thereby driving the device to move toward the b end of the wind turbine blade half mold 1. At this time, the adhesive drips from the part of the glue leakage hole 215 that is not blocked by the leakage shielding plate 217 to the closed surface of the wind turbine blade half mold 1.

[0050] When the spring 26 elastically contracts, the two rubber blocks that are in contact with the wind blade half mold 1 are squeezed toward the direction close to the wind blade half mold 1, so that the rubber blocks are squeezed to produce elastic deformation, so that they fit with the inner and outer curved surfaces of the wind blade half mold 1, and then the exposed width of the bottom of the glue storage box 213 corresponds to the glue coating width required for the closing surface of the wind blade half mold 1.

[0051] During this process, as the distance from end a to end b of the wind turbine blade half mold 1 gradually shrinks, the spring 26 gradually shrinks elastically, so that the two sets of electric wheels 22 always fit the side wall of the wind turbine blade half mold 1, and the width of the glue leakage hole 215 blocked by the leakage shielding plate 217 increases, that is, the exposed width of the bottom of the glue storage box 213 is reduced, so that during the movement of the entire device, the glue coating width can be adaptively adjusted according to the curve and width of the wind turbine blade half mold 1 to ensure accurate gluing in areas of different widths. In the narrower part, the two leakage shielding plates 217 can automatically reduce the exposed width of the bottom of the glue storage box 213; in the wider area, the exposed width of the bottom of the glue storage box 213 can be increased accordingly to ensure that the glue coating area is sufficient, thereby effectively solving the problem of difficult control of the width during manual gluing, and making the glue evenly distributed on the entire closed surface.

[0052] At the same time, multiple coatings can be avoided, ensuring that the glue layer is formed in one step, making the internal bonding of the glue layer tighter and reducing the problem of poor interlayer bonding caused by multiple coatings. This helps to improve the anti-delamination ability of wind turbine blades during operation and ensure that the glue layer can still maintain good bonding properties when the blades are subjected to complex external forces for a long time.

[0053] Embodiment 2 of the present invention:

[0054] like Figure 1 as well as Figures 7 to 9 As shown, the carbon fiber wind turbine blade adhesive coating device also includes a front-end dust suction component arranged on the glue storage box 213, and the front-end dust suction component is used to remove dust and impurities on the closed surface of the wind turbine blade half mold 1, and the front-end dust suction component includes two air guide covers 31, and the bottoms of the two electric wheels 22 located below are rotatably provided with an air guide cover 31, and the bottoms of the two electric wheels 22 located below are each installed with an electric fan 32, and the tops of the two air guide covers 31 are connected to each other and are provided with an air duct 33, one side of the glue storage box 213 is fixedly connected with a support rod 34, and the side of the support rod 34 away from the glue storage box 213 is fixedly connected with a dust cover 35, and the bottom end of the dust cover 35 is fixedly connected with a dust scraper plate 36, and the end of the air duct 33 away from the air guide cover 31 is connected to the side of the dust cover 35 away from the dust scraper plate 36.

[0055] The dust cover 35 is arranged to be wide at one side close to the support rod 1 34 and narrow at one side close to the dust scraper 36, and the narrower end of the dust cover 35 is arranged obliquely downward, and an opening is arranged at the narrower end of the dust cover 35. When in use, the bottom end of the dust scraper 36 is in contact with the closing surface of the wind turbine blade half mold 1.

[0056] When the electric fan 32 rotates, air is discharged toward the bottom of the air guide cover 31 , that is, air is sucked into the dust collection cover 35 through the air guide pipe 33 .

[0057] When the front-end dust suction component is in use, during the operation of the coating adaptive component, the electric fan 32 discharges air toward the bottom of the air guide cover 31 when it rotates, and the electric fan 32 sucks air toward the inside of the dust cover 35 through the air duct 33. At this time, the opening of the dust cover 35 sucks air toward the closing surface of the wind turbine blade half mold 1. As the electric wheel 22 moves, dust and impurities on the closing surface at the front end of the electric wheel 22 are sucked into the dust cover 35, and are discharged from the inside of the air guide cover 31 by the electric fan 32 through the air duct 33. In the process of dust suction by the dust cover 35, the scraper plate 36 moves in close contact with the closing surface of the wind turbine blade half mold 1, so as to shovel up the impurities on the closing surface of the wind turbine blade half mold 1 and separate them from the closing surface of the wind turbine blade half mold 1.

[0058] In the above process, the dust and impurities on the closing surface of the moving front end of the electric wheel 22 are sucked away by the dust hood 35, which can provide a cleaner and purer attachment surface for the adhesive. The adhesive can directly contact the closing surface of the wind turbine blade half mold 1, effectively improving the bonding effect of the glue and making the bonding between the wind turbine blade half molds 1 stronger.

[0059] Embodiment 3 of the present invention:

[0060] like Figure 1 as well as Figures 9 to 12 As shown, the carbon fiber wind turbine blade adhesive coating device also includes a rear end scraping and collecting component arranged on the glue storage box 213, the rear end scraping and collecting component is used to scrape the adhesive coated on the closed surface of the wind turbine blade half mold 1, and collect the excess overflowing adhesive, the rear end scraping component includes a support rod 2 41, the support rod 2 41 is fixedly connected to the side of the glue storage box 213 away from the support rod 1 34, the bottom end of the support rod 2 41 is fixedly connected to a scraper plate 42, both ends of the scraper plate 42 are fixedly connected to a telescopic square tube 43, the top of the telescopic square tube 43 is set to be open, the telescopic square tube 43 includes a fixed end and a telescopic end 2, the fixed end of the telescopic square tube 43 is fixedly connected to the scraper plate 42, the telescopic end 2 of the telescopic square tube 43 is symmetrically fixedly connected to two guide cylinders 44, the two guide cylinders 44 are both slidably connected to the fixed end of the telescopic square tube 43, and the surface of the two guide cylinders 44 is sleeved with a spring 3 45, and the two ends of the spring 3 45 are respectively fixedly connected to the telescopic end 2 and the fixed end of the telescopic square tube 43.

[0061] Among them: Fig. 9 and Fig.12As shown, the overall shape of the glue scraping plate 42 is set as a "V" shape, with the tip of the "V" shape close to the side of the glue storage tank 213. The cross-sectional shape of the glue scraping plate 42 is set as a "Γ" shape. The "V" shape of the glue scraping plate 42 is for guiding the bonding glue, so that the bonding glue moves along both sides of the glue scraping plate 42. The "Γ" shape of the glue scraping plate 42 is to prevent the bonding glue from piling up on the top of the glue scraping plate 42, ensuring that the bonding glue can move along both sides of the glue scraping plate 42.

[0062] During use, there is a gap between the bottom end of the glue scraping plate 42 and the closing surface of the wind turbine blade half mold 1, and this gap is used to scrape the bonding glue flat.

[0063] During use, the third spring 45 is in a compressed state, and the second telescopic end of the telescopic square tube 43 abuts against the side wall of the wind turbine blade half mold 1.

[0064] During the use of the rear-end scraping and collecting assembly, during the operation of the coating adaptive assembly, at this time, the second support rod 41 moves synchronously with the movement of the glue storage tank 213, and then the glue scraping plate 42 is driven by the second support rod 41 to move synchronously. As the glue scraping plate 42 moves, the bonding glue dripping on the closing surface of the wind turbine blade half mold 1 will abut against the glue scraping plate 42, so that the bonding glue is scraped flat in the gap between the glue scraping plate 42 and the closing surface of the wind turbine blade half mold 1, and the excess bonding glue is blocked by the top of the inner wall of the "Γ" shape of the glue scraping plate 42, making it impossible to continue to pile up upward. And at the same time, the excess bonding glue moves along both sides of the glue scraping plate 42 towards the two telescopic square tubes 43. At this time, the bonding glue flows into the inside of the telescopic square tube 43 from the top opening of the telescopic square tube 43.

[0065] As the glue scraping plate 42 drives the telescopic square tube 43 to move, under the action of the third spring 45, the second telescopic end of the telescopic square tube 43 always abuts against the side wall of the wind turbine blade half mold 1, ensuring that the telescopic square tube 43 can always collect the overflowing bonding glue. The bonding glue on the closing surface of the wind turbine blade half mold 1 is scraped flat by the glue scraping plate 42, making the surface of the already coated bonding glue smoother, making the thickness of the glue layer uniform, improving the overall quality of the bonding glue, enhancing the bonding stability, and reducing the possibility of problems such as delamination and debonding of the blade during use.
