Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade processing, and in particular to a feeding mechanism and a wind turbine blade leading edge protective coating device using the same. Background Art

[0002] Wind turbine blade damage is inevitable during long-term operation. Wind turbine blades withstand intense wind loads and the impact of sand and gravel particles, leaving them susceptible to surface defects such as scratches, corrosion, and cracks. Wind turbine blades can be hundreds of feet long and weigh thousands of pounds. Not only do they operate at high altitudes, but many are located miles away, making access difficult and dangerous. Wind turbines are typically installed in windy and sandy environments. During rotation, the blade tips are subject to high linear velocities, exceeding 70 m / s at rated speed. This causes severe wear and tear on the leading edges of the blades from the sand, leading to cracking. Currently, effective preventative measures include applying protective paint to the leading edges of the blades, particularly at the tips.

[0003] Publication number CN117696352A discloses a robot for coating the leading edge of wind turbine blades. This robot applies protective paint to the leading edge of the blades by combining a detection device for detecting direct surface data of the working area, a loading device for applying paint to the bottom and both sides of the leading edge of the wind turbine blades, and a scraping device for evenly smoothing the paint applied by the loading device. While this robot improves coating efficiency and uniformity compared to manual operation, further research and testing revealed the following issues with the robot:

Furthermore, the coating device is driven to move by a connecting rod drive assembly, realizing a non-contact spraying operation between the coating device and the wind turbine blade, avoiding the problem of the wind turbine blade blocking the discharge port of the coating device, and improving the smoothness of the coating device spraying material.

DETAILED DESCRIPTION

[0040] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0041] Example 1:

[0042] See also Figure 3 As shown, this embodiment provides a loading mechanism comprising at least: a storage bin 101 for storing paint, a pump (not shown) located above and connected to the storage bin 101, and at least one coating device 103 connected to the pump. The coating device 103 may be, for example, but not limited to, a nozzle. The pump is connected to the storage bin 101 and the coating device 103 via flexible pipes.

[0043] In terms of the layout, the storage bin 101 is located below the coating device 103, and the pump can be at the same height as the coating device 103, or the pump is located below the coating device 103 but above the storage bin 101. Under this structure, the pump pumps the material in the storage bin 101 into the coating device 103, and finally sprays it out through the coating device 103. The pump here can optionally adopt, for example but not limited to, a peristaltic pump. Based on this structure, the storage bin 101 is arranged below the pump so that the excess paint generated during the coating process that is not sprayed onto the surface of the wind turbine blade can fall back into the storage bin 101 under the action of gravity for reuse.

[0044] On the basis of the above structure, this embodiment also makes the following design:

[0045] Each coater 103 is connected to a connecting rod drive assembly for driving the coater 103 to move; the coater 103 here is designed with a connecting rod drive assembly so that there is a certain gap between the spray port of the coater 103 and the outer surface of the object to be coated, thereby realizing non-contact spraying operation between the coater 103 and the wind turbine blades, avoiding the problem of wind turbine blades blocking the discharge port of the coater 103, and improving the smoothness of the coater 103 spraying materials.

[0046] Taking an optional implementation as an example with reference to the accompanying drawings, the connecting rod drive assembly of this embodiment includes a support base 104 for fixing the coating device 103, a pair of parallel linkage rods 105 connected to the support base 104, and a synchronous pulley structure for driving the pair of linkage rods 105 to move to drive the support base 104 to move synchronously.

[0047] More specifically, the synchronous pulley structure includes a pair of transmission gears 106 connected one by one to a pair of linkage rods 105, a synchronous belt 107 connected to the pair of transmission gears 106, and a driving gear 108 connected to the synchronous belt 107; wherein the driving gear 108 is connected to a motor 109 for driving its rotation.

[0048] In this regard, it should be noted that the connecting lines between the connection points formed by a pair of linkage rods 105 and the support seat 104 and a pair of transmission gears 106 are suitable for forming a parallelogram. For the two linkage rods 105, a pair of transmission gears 106 are respectively connected to the same end of the corresponding linkage rods 105, while the support seat 104 is simultaneously connected to the other end of the pair of linkage rods 105. Based on this, in an optional implementation, a pair of linkage rods 105 adopts the same structure to facilitate the design of connection points on the linkage rods 105 that are respectively connected to the support seat 104 and the transmission gear 106.

[0049] In summary, for the feeding mechanism of this embodiment, the feeding process is simple and easy to operate, and the recycling of residual materials is taken into consideration, which can prevent the residual materials from contaminating components other than the wind turbine blades and achieve the effect of saving paint.

[0050] Example 2:

[0051] See also Figures 1 to 5 As shown, based on the feeding mechanism of Example 1, this embodiment provides a wind turbine blade leading edge protection coating device, including: the feeding mechanism, detection mechanism and scraping mechanism of Example 1 used in conjunction.

[0052] Regarding the feeding mechanism used in this embodiment, a second linear displacement sensor 110 for detecting the side end face in the length direction of the wind turbine blade is also provided on the support seat 104. The second linear displacement sensor 110 here can optionally adopt, for example, but not limited to, a magnetostrictive sensor. The second linear displacement sensor 110 is arranged side by side with the coating device 103, so that during the process of the coating device 103 spraying the coating material, the second linear displacement sensor 110 provided here can obtain the distance between the coating device 103 and the side face in the length direction of the wind turbine blade in real time, thereby facilitating the adjustment of the operating state of the motor 109 in the connecting rod drive assembly in combination with the obtained distance data, thereby driving a pair of linkage rods 105 to move through the operation of the motor 109 to adjust the distance between the coating device 103 on the support seat 104 and the wind turbine blade, thereby realizing a non-contact spraying operation between the coating device 103 and the wind turbine blade.

[0053] It should be noted that the wind turbine blade leading edge protection coating device of this embodiment also includes a bottom support frame 201 for fixing the storage bin 101; a drawer-type guide rail is provided between the storage bin 101 and the bottom support frame 201, so that the storage bin 101 can enter and leave the bottom support frame 201 along the drawer-type guide rail, thereby facilitating the addition of paint to the storage bin 101 or cleaning the storage bin 101.

[0054] Specifically, first, the feeding mechanism includes four paint applicators 103 located on both sides of the length direction of the wind turbine blade, and two paint applicators 103 are arranged on each side of the length direction of the wind turbine blade, and the two paint applicators 103 arranged on one side of the length direction of the wind turbine blade are arranged in an upper and lower manner along the width direction of the wind turbine blade. Based on this, the area of the paint spraying on the same side of the wind turbine blade is increased by the two paint applicators 103 arranged in an upper and lower manner.

[0055] Second, the detection mechanism includes at least two lateral detection assemblies located on both sides of the length direction of the wind turbine blade and at least one bottom end detection assembly located at the bottom of the wind turbine blade. Taking an example in combination with the drawings, the lateral detection assembly adopts a laser range finder 301, and the bottom end detection assembly includes a supporting block 302 suitable for supporting the bottom of the wind turbine blade, an elastic support connected with the supporting block 302, and a first linear displacement sensor 306 arranged on the elastic support and used for detecting the supporting block 302. The first linear displacement sensor 306 here can be selected, for example, but not limited to, a magnetostrictive sensor.

[0056] It should be noted here that the pair of supporting frame bodies 203 are arranged above the bottom support frame 201, and two paint applicators 103 are arranged on each supporting frame body 203 in an upper and lower manner, and two connecting rod driving assemblies corresponding to the two paint applicators 103 are arranged on each supporting frame body 203, and a laser range finder 301 is further arranged on each supporting frame body 203.

[0057] Taking an example of an elastic support in combination with the drawings, the elastic support includes a connecting rod 303 arranged between the pair of supporting frame bodies 203, a pair of guide columns 304 fixed on the connecting rod 303, and a pair of elastic members 305 sleeved on the pair of guide columns 304, respectively; the supporting block 302 is in sliding fit with the pair of guide columns 304 at the same time. The first linear displacement sensor 306 is fixed on the connecting rod 303, and can detect the distance of the supporting block 302 sliding relative to the guide column 304 relative to the connecting rod 303. The supporting block 302 in combination with the elastic support can form reliable cooperation with the wind turbine blade. In combination with different wind turbine blades, the force generated by the supporting block 302 is different, so the pressure generated by the supporting block 302 on the elastic member 305 is also different, so the distance of the supporting block 302 relative to the connecting rod 303 is also different for different wind turbine blades.

[0058] It should be further explained that the wind turbine blade leading edge protection coating device of the present embodiment further comprises a lifting driving mechanism arranged at the bottom of the bottom support frame 201 for driving the bottom support frame 201 to perform lifting movement, and an omnidirectional movement chassis for controlling the continuous movement of the wind turbine blade leading edge protection coating device as a whole. As for the lifting driving mechanism and the omnidirectional movement chassis herein, any mature means capable of achieving lifting driving and omnidirectional movement in the prior art can be adopted, such as but not limited to the lifting structure and omnidirectional movement chassis disclosed in publication CN117696352A. In this regard, the bottom detection assembly detects the lower edge of the wind turbine blade in the height direction, and then drives the bottom support frame 201 to perform lifting movement through the lifting driving mechanism, so as to maintain the fitting degree of the entire wind turbine blade leading edge protection coating device with the surface of the wind turbine blade in the height direction. The two lateral detection assemblies mainly perform distance measurement and comparison on the outer surface of the corresponding wind turbine blade, so as to ensure that the wind turbine blade leading edge protection coating device advances along the generatrix direction of the blade under the action of the omnidirectional movement chassis.

[0059] Finally, as for the squeegee mechanism, it at least comprises a squeegee support 408 and a plurality of squeegee hand claw assemblies arranged at intervals along the length direction of the wind turbine blade and arranged on the squeegee support 408.

[0060] As an example of an optional implementation, referring to the accompanying drawings, each scraping claw assembly includes two claw plates 401 arranged relative to each other to form a V-shaped receiving area for accommodating wind turbine blades, and a driving assembly for driving the two claw plates 401 to perform relative closing and opening movements. Each claw plate 401 is made of silicone material, and the hardness of the silicone material used this time can be in the range of 25 to 45a, for example, but not limited to 30a. Both the smooth scraper and the toothed scraper are made of flexible material, and the flexible material here can be, for example, but not limited to, rubber. The smooth scraper 412 and the toothed scraper 413 made of flexible material can not only meet the needs of scraping paint, but also prevent damage to the outer surface of the wind turbine blade. Most importantly, when applying paint to wind turbine blades, the claw plates 401 can leverage the micro-deformation properties of silicone to reliably adhere to the outer surface of the wind turbine blade. This effectively ensures reliable contact between the claw plates 401 and the wind turbine blade, eliminating the need for a separate structure to drive the movement of the claw plates 401, thereby ensuring the reliability of the paint application process. Specifically, the claw plates 401 can leverage the micro-deformation properties of silicone to contour to the slope of the side surfaces along the length of the wind turbine blade, ensuring a reliable fit between the claw plates 401 and the blade surface and improving the uniformity of the leading edge protective paint thickness. Furthermore, this embodiment adjusts the opening angles of the two claw plates 401 by moving them together and apart relative to each other, making the paint application gripper assembly of this embodiment suitable for wind turbine blades of varying sizes. Therefore, the scraping claw assembly of this embodiment can meet the scraping requirements for wind turbine blades of different sizes based on a relatively simple structure, and can also utilize the characteristics of the silicone material of the claw plate 401 to achieve the adaptive matching effect of the claw plate 401 with the surface to be scraped of the wind turbine blade.

[0061] On the basis of the above structure, further speaking, the driving assembly in this embodiment includes a pair of connecting frames 404 connected to the bottom corner ends of the V-shaped placement area corresponding to the two claw plates 401, a pair of linkage plates 405 connected one-to-one to the bottom corners of the two claw plates 401 away from the V-shaped placement area, and a movable plate 406 connected to the pair of linkage plates 405; wherein the pair of connecting frames 404 are simultaneously connected to a fixed plate 410, and the fixed plate 410 is fixedly connected to the scraping bracket 408 through a pair of connecting plates 407. Furthermore, the fixed plate 410 is also provided with a driving force 409 for driving the movable plate 406 to move within the movable range formed by the pair of connecting frames 404. The driving force 409 here can be directly a linear motion driver, such as but not limited to a cylinder or a linear screw module, and this embodiment does not make an absolute limitation on this.

[0062] On the basis of the above structure, it should be noted that in order to facilitate the adjustment of the inclination angle of the two claw plates 401 relative to the scraping bracket 408, the matching angle between the pair of connecting plates 407 and the scraping bracket 408 in this embodiment can be adjusted. Specifically, a plurality of connecting holes 403 are provided on the portion of the scraping bracket 408 used to match the connecting plate 407, and the plurality of connecting holes 403 include at least one connecting hole 403 located in the center and a plurality of connecting holes 403 located on the periphery distributed at intervals along the circumferential direction. Three matching holes 411 are provided on the connecting plate 408 at intervals along a straight line, wherein the matching hole 411 located in the center is matched with the connecting hole 403 located in the center, and the matching holes 411 located at both ends are selected to match with different connecting holes 403 located on the periphery, thereby realizing the adjustment of the matching angle formed by the connecting plate 407 and the scraping bracket 408.

[0063] In addition, it should be noted that the scraping bracket 408 in this embodiment is connected to the bottom support frame 201 through at least four buffer floating components. Here, an example is given in conjunction with the accompanying drawings. Each buffer floating component includes a guide column 501 fixed on the bottom support frame 201, a slider 502 mounted on the guide column 501, a connecting piece 503 connected to the slider 502, and a spring 504 mounted on the guide column 501 and suitable for being compressed and deformed as the slider 502 slides along the guide column 501. The connecting piece 503 is fixed to the scraping bracket 408. Here, through the design of the buffer floating component, the contact pressure between the claw plate 401 and the surface of the wind turbine blade to be scraped can be evenly distributed, and at the same time, the scraping claw assembly can be prevented from causing damage to the top of the leading edge of the wind turbine blade due to the large scraping force generated during the scraping process.

[0064] Finally, it is necessary to explain that, based on the loading process for spraying paint on the surface of the wind turbine blade or the scraping process for scraping paint on the surface of the wind turbine blade, there may be a problem of excess paint that needs to be recycled. Regarding the storage bin 101 of this embodiment, it is also necessary to explain that the end face of the storage bin 101 facing the paint dispenser 103 and the claw plate 401 is an open opening, and the open opening extends along the direction in which the storage bin 101 enters and exits the bottom support frame 201, so that the open opening can extend from the bottom of the several scraping claw assemblies of the scraping mechanism to the bottom of the paint dispenser 103. Based on this, both the support frame 203 and the scraping bracket 408 adopt a frame structure, so that the support frame 203 and the scraping bracket 408 are formed with a structure suitable for excess paint to fall into the storage bin 101 directly through the open opening of the storage bin 101 from the parts of the wind turbine blade corresponding to the paint dispenser 103 and the several scraping claw assemblies in the direction of gravity. This structure directly utilizes the gravity of the paint and the material receiving function of the storage bin 101 itself to realize the recycling of excess paint, without the need for an additional paint recycling structure. Therefore, it can simplify the structure of the overall wind turbine blade leading edge protection coating device to a certain extent.

[0065] In summary, the wind turbine blade leading edge protection coating device of this embodiment can not only improve the efficiency and uniformity of the wind turbine blade leading edge coating operation, but also simplify the structure of the entire device, thereby reducing production costs and failure rates in use.
